Small cardiac vein draining into the inferior vena cava.

Cardiac venous anomalies are rare congenital anatomical anomalies, which are most commonly found on computed tomography scans as an accidental finding. We report a case of a 14-year-old child who was operated for an atrial septal defect, and during the operation, we came across an anomalous drainage of the small cardiac vein into the inferior vena cava. The child's postoperative course was uneventful.

Rare Abdominal Desmoid Tumor: Case Report and Review of Literature

A desmoid tumor is a clonal fibroblast proliferation, occurring in deep soft tissues with a significant recurrence tendency. Aggressive fibromatosis is a rare disease. The prevalence in the population ranges from 2 to 4 cases per million. Mentioned neoplasms are highly unpredictable in terms of development. Typically, in the course of desmoid tumors, metastases do not occur, but they often infiltrate the surrounding tissues, which may be associated with numerous complications. There are currently no randomized standards of therapy designated, which is undoubtedly a challenge when referring to treatment. To a 37 year old patient, due to a pathological mass in the abdomen, the MR examination was performed. It showed the presence of an irregular, heterogeneous structure on the right side of the abdominal cavity. A laparotomy was performed. During the procedure adhesions were released and the giant abdominal tumor was removed in one block with part of the duodenum, caecum, ascending colon and part of ileum. End-to-end duodenal anastomosis and stapled, side-to-side ileo-transverse anastomosis were used. The surgical field was being drained. The postoperative course was uneventful. Tissue material was collected for a routine, histopathological examination in which the intra-abdominal form of fibromatosis was diagnosed. The macroscopic image describes a tumor with dimensions of 25.0 cm x 25.0 cm x 20.0 cm.

A single-center prospective analysis of the impact of glucose metabolism on pancreatic fistula onset after pancreaticoduodenectomy for periampullary tumors

BackgroundGlucose impairment notably affects the postoperative course of gastrointestinal surgeries. However, evidence on its impact on clinically relevant pancreatic fistulas(CR-POPFs) after pancreaticoduodenectomy(PD) is lacking. This study evaluates if and how preoperative glucose metabolism affects the development of CR-POPF after PD. MethodsOne hundred and ten consecutive PDs were included. Patients underwent preoperative metabolic profiling using the Oral Glucose Tolerance Test(OGTT) and the hyperinsulinemic euglycemic clamp procedure. Accordingly, patients were categorized as normal glucose tolerant (NGT), impaired glucose tolerant (IGT), diabetic (DM), and longstanding-DM. Receiver operating characteristics(ROC) analyses were performed to determine the values of metabolic features in prediction of CR-POPF. ResultsThe CR-POPF rate was 36.3 ​%(40 patients). NGT patients had a higher CR-POPF rate (51.7 ​%) compared to IGT(45.2 ​%), DM (15.8 ​%), and longstanding-DM (25.8 ​%) (p ​= ​0.03). CR-POPF patients had lower median fasting glucose levels (p ​= ​0.01) and higher c-peptide values at all OGTT time points (p ​< ​0.05). Fasting glucose and c-peptide levels had high diagnostic accuracy for CR-POPF (AUC>0.8) and were independent risk factors for CR-POPF (OR: 24.7[95%CI: 3.7–165.3] for fasting glucose; OR: 19.9[95%CI: 3.2–125.3] for c-peptide). ConclusionNormoglycemia and normal beta cell function may be risk factors for CR-POPF after PD. Fasting glucose and c-peptide levels effectively predicted CR-POPF development following PD.

Appendiceal Bleeding, A Rare Yet Important Cause of Lower Gastrointestinal Bleed.

Lower gastrointestinal bleeding accounts for 20 to 25% of all gastrointestinal bleedings. Appendiceal bleeding is a rare, yet important cause of lower gastrointestinal bleed; in many cases, it can be misdiagnosed as obscure gastrointestinal bleeding. Here, we present a case of appendiceal bleeding in an elderly female. A 79-year-old female presented with acute onset of gastrointestinal bleeding of same-day duration. Investigations showed that she had an appendiceal bleed originating from an ulcer secondary to a small appendicolith, which has passed through the appendiceal orifice, combined with her aspirin use. Within 12 hours, a laparoscopic appendectomy was performed. No evidence of malignancy or vascular malformation was detected, and the post-operative course was smooth, with resultant discharge at day 3 after her surgery. For lower gastrointestinal bleeding, it is crucial for the endoscopist to reach the terminal ileum during the colonoscopy, and thoroughly inspect the orifice of the appendix to assess any source of bleed including but not limited to Dieulafoy's lesion, angiodysplasia or any vascular malformation. An effective treatment option for appendiceal bleeding is surgical management with appendectomy. Alternative approaches such as vessel embolization and endoscopic treatment have been reported to successfully control bleeding; nevertheless, the risk of acute appendicitis and recurrent bleeding following these procedures can be challenging to manage, potentially leading the patient to still need a surgical treatment with an appendectomy. Appendiceal bleeding is a rare, yet important cause of lower gastrointestinal bleed; in many cases, it can be misdiagnosed as obscure gastrointestinal bleeding.

An invasive and diffuse cranial actinomycosis with a dura-based mass mimicking a brain tumor: illustrative case.

Actinomycosis is a chronic suppurative infection caused by non-spore-forming, anaerobic, and filamentous gram-positive bacteria. Primary central nervous system involvement is rare, with no specific clinical features, causing a clinical diagnostic dilemma. Imaging can help in localizing and characterizing the lesion; however, a definitive diagnosis relies on culture and/or histopathology. The authors describe a 29-year-old male farmer with a rare case of invasive and diffuse cranial actinomycosis with a dura-based mass mimicking a brain tumor. Brain magnetic resonance imaging showed a moderately enhanced right frontoparietal infiltrative dura-based mass with marked thickening of the skull and multiple scalp actinomycotic abscesses. He underwent microsurgical excision of the mass, orbital decompression, and debridement of the scalp abscess. Histopathology confirmed actinomycosis, and his postoperative course was uneventful. Invasive and diffuse cranial actinomycosis with a dura-based actinomycetoma is a rare presentation that poses a diagnostic challenge due to its nonspecific manifestations. Imaging is helpful in localizing and characterizing the lesion; however, histopathology remains the gold standard for diagnosing actinomycosis. A high index of suspicion is also warranted in patients with predisposing factors to promote an early diagnosis and the initiation of appropriate treatments to improve functional recovery and limit residual deficits. https://thejns.org/doi/10.3171/CASE24210.

Foreign Body Trapped in the Oropharynx Requiring Emergency Tonsillectomy in a Case at Nianankoro Fomba Hospital in Ségou

Introduction: Pharyngeal foreign bodies, particularly in oropharyngeal locations, should raise concerns about the presence of an associated wound. They constitute a common pathology. Their diagnosis is most often easy, but difficult in the case of an unknown foreign body. We report a foreign body embedded in the lateral wall of the oropharynx which required emergency tonsillectomy. Observation: This is a 6-year-old child received urgently at the Nianankoro Fomba Hospital in Ségou 6 hours after the introduction of the foreign body (wheel spoke) into the tonsillar compartment. On admission to the ENT and head and neck surgery department, the child&amp;apos;s general condition was poor, consciousness remained and the conjunctivas were normal-colored. On oropharyngeal examination, we note a sharp metallic foreign body measuring 30 cm and 2 mm in diameter located at the level of the posterior fold of the right amygdala. Furthermore, there is hypersialorrhea with blood streaking. Faced with the failure of an extraction attempt; we decided to take him to the operating room after a minimum assessment. The immediate postoperative course was unremarkable. The evolution was very favorable on the 10th day of the intervention. Conclusion: Pharyngeal foreign bodies constitute a vital emergency due to their appearance or location. Their management requires rapid intervention with suitable equipment. Prevention remains the best solution.

MASSIVE HEMORRHAGE DUE TO RUPTURE OF A RIGHT ILIAC ANEURYSM REVEALING BEHCET'S DISEASE: A CASE REPORT FROM THE FESTOC CENTER IN BAMAKO

INTRODUCTION: Behçet's disease is a chronic inflammatory disorder. It is clinically characterized by oral and genital aphthoses; skin lesions and systemic manifestations. Arterial aneurysms are defined as a loss of parallelism of the arterial walls, localized to an arterial segment, and corresponding to an increase of at least 50% of the normal arterial diameter. We report a case of Behcet's disease revealed by a ruptured aneurysm of the right primitive iliac artery. OBSERVATION: This was a 44-year-old patient with no known history, referred for management of a right inguinal mass that had progressively increased in volume and had been evolving for about 1 month. On admission, the physical examination revealed conjunctival pallor, a pulsatile right inguinal mass approximately 10 cm in diameter, and a suppurating sore on the scrotum. Doppler ultrasound of the lower limbs revealed an aneurysm of the right common iliac artery. The aneurysm ruptured during the short preparation period for surgery, resulting in cataclysmic hemorrhage. This prompted manual compression and the transfusion of several packed red blood cells. During transport to the OR, the patient experienced hemorrhagic shock and altered consciousness, prompting the administration of drugs (noradrenaline) and emergency orotracheal intubation. The aneurysm was controlled upstream and downstream by approaching the right primitive iliac artery, followed by dissection and clamping after general heparinization. The common femoral artery was then approached and checked. Surgical exploration revealed numerous clots which were evacuated, revealing a large neck extending over 7 cm. The procedure involved reconstruction of the common femoral artery with a patch saphenous graft and excision of the necrotic tissue. The post-operative course was marked by suppuration of the surgical wound, which progressed well with appropriate antibiotics and local care. CONCLUSION: Arterial involvement in Behçet's disease manifests as arterial thrombosis or, more frequently, aneurysm. This is due to inflammation of the media, intima and vasa vasorum. Their management can be envisaged in our context.

Minimal Invasive Resection of Large Retrosternal Thyroid Goiter.

Resecting a large goiter extending into the retrosternal space is challenging, especially when a sternotomy or thoracotomy is required. The transthoracic approach is linked to higher postoperative morbidity, reaching up to 30% when compared to the transcervical approach. Although alternative options like thoracoscopic resection have shown promising results, the morbidity of mediastinal dissection remains a concern. Thoracoscopic-assisted transcervical approach might be a feasible, less invasive alternative. This video outlines the steps and potential pitfalls of the procedure. The patient is positioned supine with an extended neck. Initially, the endocrine surgeon mobilizes the thyroid gland through cervical access. If a transcervical resection is not feasible, the patient is mobilized into a lateral decubitus position, and a second team thoracoscopically guides the mediastinal tumor through the thoracic inlet. This allows a stepwise controlled transcervical dissection of the retrosternal mass until complete resection is achieved, thus eliminating the need for mediastinal dissection. To demonstrate the procedure, we present the case of an 84-year-old male with lymph node-positive oncocytic thyroid carcinoma and a large retrosternal goiter extending posteriorly into the mediastinum up to the aortic arch. Thoracoscopic-assisted transcervical resection was performed. The recurrent laryngeal nerve was identified and monitored with a neurostimulation device during dissection. No palsy was noted in the postoperative evaluation. The patient had an uneventful postoperative course and was discharged on the second postoperative day. Thoracoscopic-assisted transcervical resection of large retrosternal goiter seems a feasible alternative to mitigate risks associated with thoracotomy, sternotomy, or thoracoscopic mediastinal dissection. Potential advantages include decreased postoperative morbidity and length of stay. This technique requires thoracoscopic expertise and may be limited depending on the goiter's size and mediastinal positioning.

Simultaneous beating-heart mitral valve replacement and aortic repair following Bentall procedure via double right mini-thoracotomies: a case report

BackgroundRedo mitral valve surgery by re-sternotomy approach has challenges such as bleeding and organ injury due to adhesion dissection, sternal bone infection, and poor field of view of mitral valve. On the other hand, redo mitral valve surgery via a right mini-thoracotomy approach appears to address these challenges. We successfully performed a double right mini-thoracotomies approach for mitral valve replacement and pseudoaneurysm repair under the beating-heart condition. Herein, we report the effectiveness and the safety of this technique and detailed procedure.Case presentation.The patient is a 71-year-old man with a history of Bentall procedure using a mechanical valve at another hospital 30 years ago. He developed acute heart failure due to severe mitral valve regurgitation. After medication, he was referred to our department for the purpose of surgery for mitral valve regurgitation. Preoperative transesophageal echocardiography showed extensive degenerative change of the both leaflets and chordae tendineae rupture at the P3 segment. Both left atrium and ventricle dilated, and left ventricle contractility reduced. Aortic mechanical valve had no problem. In addition, preoperative contrast enhanced computed tomography revealed a pseudoaneurysm at the distal anastomotic site of Bentall procedure. We performed mitral valve replacement by mechanical valve and repair of distal anastomotic cite under beating heart condition, utilizing a double right mini-thoracotomies approach for mitral valve and ascending aortic pseudoaneurysm respectively. The postoperative course was uneventful, the patient was discharged without complications.ConclusionThe right mini-thoracotomies approach efficiently accessed mitral valve and ascending aorta in reoperations, reducing the adhesion dissection risks and ensuring clear exposure. Moreover, concomitant use of beating-heart technique minimized adhesion dissection for aortic cross-clamp, preserved cardiac function.

Comparison of Outcomes after Autologous Breast Reconstruction: Latissimus Dorsi with Immediate Fat Transfer versus Abdominally Based Free Flaps.

Autologous breast reconstruction confers favorable patient reports of satisfaction and quality of life compared with implant-based reconstruction over a lifetime. The latissimus dorsi with immediate fat transfer (LIFT) is an alternative approach to abdominally based free flaps (Ab-FF), which expands fully autologous reconstruction to nonmicrosurgeons. This study compared the 2 procedures concerning their clinical and patient-reported outcomes 1 year postoperatively. The authors conducted a retrospective review of LIFTs and Ab-FFs performed between March of 2017 and August of 2022. The primary outcomes were postoperative complications, reoperations, and longitudinal BREAST-Q scores. BREAST-Q modules included Satisfaction with Breasts, Satisfaction with Abdomen, Satisfaction with Back, Psychosocial Well-being, Physical Well-being: Chest, Physical Well-being: Abdomen, Physical Well-being: Back, and Sexual Well-being. Of the 281 included patients (408 breasts), 211 received Ab-FF and 70 received LIFT. One-year follow-up (median [interquartile range], 12 [12] months) demonstrated that Ab-FF independently predicted dehiscence, reoperation procedures, and revisional surgery. LIFT independently increased the odds of seroma. Obesity predicted dehiscence, and bilateral reconstructions predicted revisional fat grafting. BREAST-Q scores fluctuated over time but were similar across all measured domains by 1 year postoperatively. Although Ab-FF is the standard approach for fully autologous reconstruction, LIFT procedures may be associated with a less complicated postoperative course while eliciting similar patient-reported outcomes. LIFT may be preferred to limit postoperative complications, particularly in patients with obesity. LIFT can be used by plastic surgeons who are not trained in microsurgical procedures or do not have an environment that fosters Ab-FF. Therapeutic, III.

Early removal of transorbital penetrating traumatic brain injury by a wooden object: a case report

Introduction and Importance: Transorbital penetrating traumatic brain injury (TPTBI) is a rare cause of penetrating head injury, yet the diagnoses can be overlooked in some cases due to incomplete history, trivial trauma, and the absence of immediate neurologic deficits. Case Presentation: A 4-year-old male child was admitted with a diagnosis of TPTBI by a wooden object. Non-contrast enhanced CT scan revealed a linear hypodense structure extending from the superior wall of the right orbit into the frontal lobe with displaced fragments into the brain. Additionally, cerebral contusion, pneumocephalus, and hematoma with surrounding edema were seen in the frontal lobe. Early extraction of the foreign body was performed by a multidisciplinary team of Neurosurgeons and Ophthalmologists. The wooden fragment of size 10 cm×1 cm×1 cm was removed by a small mini-craniotomy of the right frontal supraorbital bone with the gentle pulling of it through the dura mater and frontal cortex. The postoperative course was uncomplicated, vision was restored, and there were no neurologic deficits at the time of discharge on the 7th postoperative day with good postoperative outcomes. Clinical Discussion: Delayed removal of TPTBI may be complicated by misidentification of entry points, extensive scarring around the foreign body, adherence to the intracranial vessels, and increasing mortality due to infectious complications. Therefore, early exploration with the help of a multidisciplinary team will most likely result in successful debridement, good neurologic outcomes, and lower morbidity and mortality. Conclusion: Accurate diagnosis and early intervention for TPTBI may prevent possible infectious and neurologic complications.

Giant gallbladder cyst with acute cholecystitis: a case report

BackgroundGallbladder cysts are rare diseases with very few reported cases, and no clinical or histological definition has been established. Furthermore, cases of giant cysts outside the gallbladder wall are extremely rare. We report a rare case of giant gallbladder cyst with acute cholecystitis.Case presentationAn 85-year-old woman with appetite loss and right lower abdominal pain lasting 2 days presented to our hospital. At first, the patient’s abdominal pain was mild to moderate with no fever. Blood tests revealed a white blood cell count of 10,950/mm3, and the C-reactive protein (CRP) level was 14.35 mg/dl. A contrast-enhanced computed tomography (CT) scan of the abdomen revealed a grossly distended gallbladder (14.5 × 14.5 × 8.7 cm) with an incarcerated stone in the cystic duct. The patient was treated by percutaneous transhepatic gallbladder drainage (PTGBD) with 735 ml of drainage fluid. Oral contrast magnetic resonance cholangiopancreatography (MRCP) revealed that gallbladder swelling remained (14.0 × 6.5 cm) 3 days after PTGBD. We performed laparoscopic cholecystectomy 6 days after PTGBD. Because of the severe adhesion around the junction of the cystic and common bile ducts, we performed open cholecystectomy.The resected specimen was 14 × 11 cm in size and consisted of a gallbladder (6 × 7 cm) with a stone (2.4 × 1.8 cm) in the gallbladder and a large cystic lesion (18 × 18 cm) outside the gallbladder wall. The cystic lesion had a wall thickness of 6 to 12 mm and internal septal structures and contained hemorrhagic and necrotic tissue.Histological examination revealed that the specimens showed a mildly swollen gallbladder and a cystic lesion on the outside of the gallbladder wall, adjacent to the gallbladder wall, with wall thickening and inflammation. The cystic lesion suggested gallbladder duplication, gallbladder diverticulum or extension of the Rokitansky-Aschoff sinus (RAS). There was no malignancy. The patient’s postoperative course was uneventful, and she was discharged 5 days after the operation.ConclusionWe present a very rare case of giant gallbladder cyst with acute cholecystitis revealed by cholecystectomy.

Surgical indication and management of obstructive colonic metastasis from primary lung adenocarcinoma: report of a case and review of the literature

BackgroundColonic metastasis from lung cancer is very rare and is typically associated with poor prognosis. Herein, we report the case of a patient who achieved intermediate-term survival using a multimodal treatment approach, including chemotherapy, immunotherapy, radiotherapy, and surgical resection for obstructive colonic metastasis from primary lung adenocarcinoma.Case presentationA woman in her 50s presented with anemia and a positive fecal occult blood test. Computed tomography revealed a tumor in the right upper lobe of the lung with mediastinal lymphadenopathy and wall thickening in the transverse colon. Colonoscopy revealed a stricture involving 50% of the colonic lumen. Biopsy revealed a poorly differentiated adenocarcinoma positive for CK-7 and TTF-1, very focally positive for napsin A, and negative for CK-20 and CDX-2. Furthermore, positron emission tomography/CT (PET/CT) showed a high maximum standardized uptake value (SUVmax) of 8.2 in the iliac bone. Based on these findings, the patient was diagnosed with primary lung adenocarcinoma with simultaneous metastasis to the transverse colon and iliac bone (cT4N3M1c, cStage IVB).After receiving first-line chemotherapy with atezolizumab, pemetrexed, and carboplatin, the tumors shrank after 4 courses. Subsequently, the patient received maintenance therapy with atezolizumab and pemetrexed. However, the tumor enlarged after 10 courses. Second-line chemotherapy with docetaxel and ramucirumab (3 courses) failed to achieve tumor reduction. Colonoscopy revealed an impassable colonic tumor. Nineteen months after diagnosis, surgery was planned for imminent intestinal obstruction.We determined that the colonic tumor was resectable, because laparoscopic exploration revealed no other metastases. The tumor was resected by partial colectomy with ileocolonic anastomosis. The postoperative course was uneventful. Pathological examination revealed a resection margin that was negative for malignancy, and the histological type was consistent with metastatic lung adenocarcinoma.The patient then received nab-paclitaxel therapy; however, she developed symptoms of superior vena cava syndrome after 3 courses. The patient received palliative irradiation (30 Gy/10 fr) followed by nivolumab. She soon developed a solitary brain metastasis, and stereotactic irradiation was planned. After 3 courses of nivolumab, the metastasis was reduced significantly, and stereotactic brain irradiation was canceled. The lung tumor and mediastinal lymphadenopathy gradually shrank, and the patient survived for 13 months after surgery without disease progression.ConclusionsIn this case, surgical resection of colonic metastasis from primary lung adenocarcinoma may have contributed to the short-term prognosis as a bridge-to-next available multimodal treatment.

Laparoscopic Central Pancreatectomy with Modified Blumgart Pancreatojejunostomy for Pancreatic Neuroendocrine Tumor.

This report with a video describes a laparoscopic central pancreatectomy with modified Blumgart pancreatojejunostomy for pancreatic neuroendocrine tumor. A 71-year-old woman presented with a single 17 mm lesion in the pancreatic neck, responsible for dilatation of the main pancreatic duct. Cancer staging showed no additional location. Somatostatin receptor imaging was positive. After a multidisciplinary discussion in the French national reference network for the management of neuroendocrine tumor (RENATEN) surgery with central pancreatectomy was decided. The operation time was 320 min and the estimated blood loss was less than 100 ml. Final pathology confirmed a pancreatic NET of 13 mm staged as T1 N0 M0 R0 G1 with a Ki-67 of 2%. After lymph node dissection, five nodes were analyzed and were found to be noninvaded. The postoperative course was uneventful. Laparoscopic central pancreatectomy is an excellent alternative for sparing pancreatic parenchyma.

Indications and outcomes for locoregional perforator propeller flaps in head and neck reconstruction: Topographical approach in 83 patients

BackgroundLocal perforator flaps have been used in head and neck for coverage of relatively small defects. In this study, we aimed to present our results using a wide spectrum of locoregional flaps in perforator propeller fashion in reconstruction of moderate-to-large sized soft tissue defects of the head and neck. Patients and MethodsFrom August 2012 to June 2023, a total of 83 patients with moderate to large-sized soft tissue defects of the head and neck underwent reconstruction using locoregional perforator propeller flaps. Data on the etiology and location of the defect, the flap of choice and the postoperative course were gathered from patients’ charts retrospectively. Clinical outcome was evaluated based on parameters such as flap survival, color match, duration of hospitalization, and subjective satisfaction of the patient. ResultsA total of 92 locoregional perforator propeller flaps were used in 83 patients with skin and soft tissue defects of the head and neck. The follow-up period ranged from 3 and 36 months, with an average follow-up duration of 12 months. The duration of hospitalization varied between 1 and 6 days, averaging 3 days. Distal partial flap loss occurred in 3 patients, while no postoperative infection, hematomas or seromas were observed. ConclusionLocoregional perforator propeller flaps provide reproducible, functional and aesthetic results in reconstruction of moderate-to-large sized soft tissue defects of the head and neck.

Traumatic middle meningeal arteriovenous fistulas (MMAVFs): an exploratory systematic review.

This study aims to systematically review case reports and case series in order to compare the postoperative course of conservative, endovascular and surgical treatments for traumatic dural arteriovenous fistulas predominantly supplied by the middle meningeal artery (MMAVFs), which usually occur following head trauma or iatrogenic causes. We conducted a comprehensive search of PubMed, Embase, Scopus, Web of Science, and Google Scholar until June 23rd, 2024. Three cohorts were defined based on the treatment modality employed. The primary outcomes were the rates of overall obliteration and postoperative complications, with all-cause mortlality considered as secondary outcome. A total of 61 studies encompassing 78 pooled MMAVFs were included in the qualitative analysis. The predominant demographic consisted of males (53.9%) with a median age of 50.5 (IQR: 33.5-67.5) years. The main etiologies for fistula formation were head trauma (75.6%), cranial neurosurgical procedures (11.5%) and endovascular embolization (8.97%). Venous drainage patterns were categorized as follows based on anatomical confluence: Class I (16.7%), II (14.1%), III (12.8%), IV (14.1%), V (7.7%), and VI (3.9%). Regarding treatment efficacy, the overall obliteration rate was 89.74%, achieved through endovascular (95.83%), surgical (64.29%) or conservative (93.75%) approaches. In terms of safety, the overall postoperative complication rate was 6.49% with an all-cause mortality rate of 8.97%, predominantly observed in the surgical group (35.71%). Our systematic review highlights the challenging management of traumatic MMAVFs, frequently associated with head injuries. Endovascular therapy has emerged as the predominant treatment modality, demonstrating markedly higher rates of fistula obliteration, reduced all-cause mortality, and fewer postoperative complications.

Liposomal Bupivacaine Does Not Decrease Postoperative Pain in Patients with Intracapsular Femoral Neck Fracture Treated with Hemiarthroplasty: HEAT-A Randomized, Controlled Trial.

Liposomal bupivacaine (LB) is a long-lasting local anesthetic agent that was developed for use in the surgical setting to help manage postoperative pain. The objective of this study was to evaluate the effect of LB on postoperative pain, function, and overall hospital course in patients with intracapsular hip fractures who were treated with hip hemiarthroplasty. This was a single-center, randomized prospective double-blinded study of 50 patients with an isolated intracapsular femoral neck fracture who were treated with hip hemiarthroplasty from 2018 to 2022. The study group consisted of 25 patients who were treated with intraoperative LB and bupivacaine hydrochloride injections, while the control group consisted of 25 patients who were treated with intraoperative bupivacaine hydrochloride injections only. Primary outcomes were a visual analog scale (VAS) score for pain, total morphine milligram equivalents (MME), delirium, and time to ambulation with physical therapy. No significant differences between the study and control groups were found in any of the outcomes measured. Most notably, there were no differences in the average postoperative pain score (VAS, 2.26 versus 2.7; p = 0.34), total MME used postoperatively (11.73 versus 9.98 MME; p = 0.71), and postoperative day of discharge (4.00 versus 3.88 days; p = 0.82). The results of our study suggest that use of LB is not associated with substantially improved postoperative pain or function or with a shorter hospital course following hip hemiarthroplasty for a femoral neck fracture. Given the higher cost of LB compared with standard postoperative pain modalities, it is worth questioning its use in the setting of geriatric hip fractures. Therapeutic Level I.

Evaluating mechanical benefit of wedge osteotomies in endoscopic surgery for sagittal synostosis using patient-specific 3D-printed models.

Endoscopically assisted sagittal strip craniotomy with subsequent cranial orthosis is a frequently used surgical approach for non-syndromic sagittal synostosis. Originally, this technique involved a wide sagittal strip craniectomy with bilateral wedge osteotomies. More recent studies suggest omitting wedge osteotomies, achieving similar outcomes. The controversy surrounding wedge osteotomies and our efforts to refine our technique led us to create models and evaluate the mechanical impact of wedge osteotomies. We conducted a 3D-print study involving preoperative CT scans of non-syndromic scaphocephaly patients undergoing minimally invasive-assisted remodelation (MEAR) surgery. The sagittal strip collected during surgery underwent thickness measurement, along with a 3-point bending test. These results were used to determine printing parameters for accurately replicating the skull model. Model testing simulated gravitational forces during the postoperative course and assessed lateral expansion under various wedge osteotomy conditions. The median sagittal strip thickness was 2.00mm (range 1.35-3.46mm) and significantly positively correlated (p = 0.037) with the median force (21.05 N) of the 3-point bending test. Model testing involving 40 models demonstrated that biparietal wedge osteotomies significantly reduced the force required for lateral bone shift, with a trend up to 5-cm-long cuts (p = 0.007). Additional cuts beyond this length or adding the occipital cut did not provide further significant advantage (p = 0.1643; p = 9.6381). Biparietal wedge osteotomies reduce the force needed for lateral expansion, provide circumstances for accelerated head shape correction, and potentially reduce the duration of cranial orthosis therapy.

A rare case of central nervous system pancreatoblastoma metastasis: illustrative case.

Pancreatoblastoma is a malignant neoplasm of the pancreas, occurring usually in children and rarely in adults. Treatment consists of surgery with a variable combination of adjuvant therapies. Liver metastases are common, whereas brain diffusion is exceptionally rare. The authors report the case of a 42-year-old man with a 16-year history of metastatic pancreatoblastoma, previously treated with surgery, chemotherapy, and radiotherapy, demonstrating a partial response. He presented with headache and dizziness, and brain magnetic resonance imaging (MRI) showed a cerebellar lesion. A craniotomy was performed with complete tumor removal, and the postoperative course was uneventful. Brain MRI showed gross-total resection of the lesion, and the patient was discharged with an improvement of the preoperative symptoms. Histopathological analysis confirmed the diagnosis of metastasis from pancreatoblastoma. The patient received adjuvant stereotactic radiotherapy and showed further clinical improvement at the last follow-up. Brain metastases from pancreatoblastoma are exceptionally rare and poorly described in the literature. There is no standard therapy for this condition; hence, patients usually undergo treatments similar to those for other central nervous system metastases. All the described patients have had good clinical outcomes yet short-term follow-ups; therefore, further investigations are needed to better understand the best treatments for this condition. https://thejns.org/doi/10.3171/CASE23764.

Meningiomas in Elderly Subjects: Retrospective Studies of 8 Cases and a Literature Review

Aim. Intracranial meningiomas in adults are mainly benign tumors that develop from the meninges. They are common, accounting for about 18 to 20% of primary intracranial tumors, and they are slow-growing, with a predominance in women. They can occur at any age but are most common after the age of 56. Symptoms vary depending on the location of the tumor, its size, and the anatomical structures it comes into contact with. Surgery is the main treatment modality for meningiomas. The objective of this study is to evaluate the cases of meningiomas in our series and to compare their different aspects, such as epidemiological, clinical, radiological, therapeutic, histological, evolutionary, and prognostic characteristics, with those reported in other series of the literature. We seek to highlight the similarities and differences between our series and previous studies, considering recent advances in this field. Materials and measures. In our series, the retrospective study of 8 cases of intracranial meningioma in elderly subjects diagnosed and operated on at the Neurosurgery Department of a hospital over a period of 4 years. Brain CT and MRI were the primary preoperative diagnostic means. The use of these imaging techniques was essential to establish the diagnosis and plan the surgical procedure. The histopathological study was performed to confirm the post-operative diagnosis and determine the histological type, as well as the grade of the meningiomas, referring to the WHO classification to plan an appropriate follow-up of the management. Results. Meningiomas accounted for 2.33% of intracranial meningiomas in elderly subjects, and 22.22% were in subjects under 65 years of age out of 342 tumors operated on in the Department during the same period. The female predominance was clear, at 62%, compared to 38% for men. The average age of our patients was 69.9 years, with extremes of 65 and 74 years. The main clinical symptoms observed in our patients were headache, motor deficit (hemiparesis, hemiplegia), sensory deficit, convulsions, and cranial pair involvement (optic nerve and facial nerve).On CT, the tumor mass was spontaneously hyperdense in 100% of cases. After the injection of iodine product, there was a homogeneous intense contrast intake in all cases. Only 2 patients in our series performed CT scans, of which we found perilesional edema and mass effect in 100% of cases. No calcifications or bone abnormalities were detected. MRI was performed on all our patients, allowing us to better specify the topographical diagnosis of meningiomas.
