Early and Late Surgery-Free Rates of Conservative Management Strategy for Thrombosed Type A Acute Aortic Dissection and Acute Intramural Hematoma.

Background: We have employed a conservative management approach, including intensive control of both blood pressure and heart rate, in patients with aortic intramural hematoma (AIMH) and retrograde thrombosed type A acute aortic dissection (RT-TAAAD), sharing common clinical and imaging characteristics. Methods: To evaluate the outcomes of our conservative management approach, we retrospectively reviewed the clinical records of 98 patients diagnosed with AIMH or RT-TAAAD from January 2008 to March 2023. A conservative management approach was applied, except for those patients with an aortic diameter ≥ 55 mm, false lumen expansion, or cardiac tamponade, who underwent emergency aortic repair. Results: Besides 2 patients, who declined surgery and subsequently died from aortic rupture, 18 patients underwent urgent aortic surgery, while 78 did not. Multivariable logistic regression analysis identified the extrusion type of ulcer-like projections (ULPs) on admission and a maximum aortic diameter ≥ 45 mm on Day 1 as risk factors for acute aortic surgery. Among the 78 patients who were discharged, 9 (12%) underwent aortic surgery, while 69 (88%) did not, with a median follow-up of 44 months. The overall actuarial aortic surgery-free rates were 78% at 1 year and 72% at 5 years, respectively. A Cox proportional hazards analysis identified ULPs and an aortic diameter ≥ 45 mm at discharge as risk factors for late aortic surgery. Conclusions: The early and late outcomes of our conservative strategy for AIMH and RT-TAAAD demonstrate favorable surgery-free rates. The extrusion type of ULPs on admission and an aortic diameter ≥ 45 mm on Day 1 are predictors of acute aortic surgery, while ULPs and an aortic diameter ≥ 45 mm at discharge are predictors of late surgery.

Ascending aortic aneurysm after acute aortic dissection in a case with systemic lupus erythematosus

A 50-year-old woman with systemic lupus erythematosus and a history of aortic arch replacement surgery for Stanford type A aortic dissection experienced a reoccurrence of an ascending aortic aneurysm and coronary artery occlusion. Computed tomography revealed that the aneurysm was compressing the superior vena cava and right atrium. The patient underwent urgent surgery to repair the aneurysm. This case highlights that aortic aneurysms can reoccur even after total arch replacement in systemic lupus erythematosus patients.

Postoperative physical rehabilitation in the elderly patient after emergency surgery. Influence on functional, cognitive and quality of live recovery: study protocol for a randomized clinical trial

BackgroundThe progressive aging of the population has meant the increase in elderly patients requiring an urgent surgery. Older adults, especially those with frailty, have a higher risk for complications, functional and cognitive decline after urgent surgery. These patients have their functional and physiological reserve reduced which makes them more vulnerable to the effects of being bedridden. The consequences are at multiple levels emphasizing the functional loss or cognitive impairment, longer stays, mortality and institutionalization, delirium, poor quality of life and increased use of resources related to health.We aim to determine whether postoperative physical rehabilitation can prevent functional and cognitive decline and modify the posterior trajectory.Methods/designThis study is a randomized clinical trial, simple blinded, conducted in the Department of Surgery of a tertiary public hospital in Navarra (Hospital Universitario de Navarra), Spain. Patients > = 70 years old undergoing urgent abdominal surgery who meet inclusion criteria will be randomly assigned to the intervention or control group. The intervention will consist of a multicomponent physical training programme, which will include progressive and supervised endurance, resistance and balance training for 4 weeks, twice weekly sessions with a total of 8 sessions, and the group control will receive the usual care. The primary outcome measure is the change in functional (SPPB) and cognitive status (Mini-Mental State Examination) and the change of quality of life (EuroQol-5D-VAS) during the study period. The secondary outcomes are postoperative complications, length of stay, delirium, mortality, use of health resources, functional status (Barthel Index and handgrip strength tests), cost per quality-adjusted life year and mininutritional assessment. The data for both the intervention group and the control group will be obtained at four different times: the initial visit during hospital admission and at months 1, 3 and 6 months after hospital discharge.DiscussionIf our hypothesis is correct, this project could show that individualized and progressive exercise programme provides effective therapy for improving the functional capacity and achieve a better functional, cognitive and quality of life recovery. This measure, without entailing a significant expense for the administration, probably has an important repercussion both in the short- and long-term recovery, improving care and functional parameters and could determine a lower subsequent need for health resources. To verify this, we will carry out a cost-effectiveness study.The clinical impact of this trial can be significant if we help to modify the traditional management of the elderly patients from an illness model to a more person-centred and functionally oriented perspective. Moreover, the prescription of individualized exercise can be routinely included in the clinical practice of these patients.Trial registrationClinicalTrials.gov Identifier: NCT05290532. Version 1.

Prothrombin complex concentrate for direct factor Xa inhibitor-associated bleeding or before urgent surgery

IntroductionFactor Xa inhibitor (FXaI)-associated bleeding events are common and associated with substantial morbidity. Systematic evaluation of widely available, effective, and affordable FXaI bleed management strategies is needed. Materials and methodsWe conducted a single-center retrospective cohort study of FXaI-treated patients presenting to a tertiary academic medical center from January 2018 to May 2019 who received 25–50 IU/kg 4F-PCC for either FXaI-associated major bleeding or urgent surgery. The primary outcome was hemostatic efficacy, and the safety outcome was the 30-day risk of thromboembolism. ResultsPCC was used to treat FXaI-associated bleeding in 83 cases (79.1 %) and was given before urgent surgery in 22 cases (20.9 %). Sixty-six patients were on apixaban, 38 were on rivaroxaban and one patient was on edoxaban. Intracranial hemorrhage (ICH) and gastrointestinal bleeding accounted for most bleeds (74.7 %). Median interval between last DOAC intake and presentation to triage was 9 h [IQR 5.3–14.8] and median PCC dosing was 40.0 IU/kg [IQR 28.5–46.6]. Forty-two patients (40.0 %) had pre-PCC FXaI levels drawn with median FXaI levels of 114.5 ng/mL [IQR 70.0–175.0]. Effective hemostasis occurred in 66.7 % [95%CI 55.4–76.3] of patients receiving PCC for bleeding and surgical hemostasis was rated as normal in 95.5 % (95%CI 76.5–100.0) for patients having urgent surgery. The 30-day risk of thromboembolism was 7.6 % [95%CI 3.7–14.5] and 22.9 % [95%CI 15.8–31.8] of patients died. ConclusionsPCC for FXaI-associated bleeding was associated with hemostatic efficacy in two-thirds of patients and thromboembolic events were uncommon. PCC represents a promising treatment strategy for FXaI-associated bleeding.

Association of non-English language preference with postoperative hospital visits among California Medicaid enrollees

BackgroundPatients with non-English language preference encounter language barriers across phases of surgical care. Patients with a non-English language preference represent 35% of California households and are disproportionately insured by Medicaid. To determine whether language predicts surgical outcomes, we investigated the association of patient non-English language preference with postoperative emergency department visits and readmissions among California Medicaid enrollees. MethodsOur retrospective analysis of adult Medicaid enrollees undergoing 1 of 10 common inpatient operations using California hospital administrative data (2016–2019) modeled the association between non-English language preference and 30-day postoperative emergency department visits and readmissions using mixed effects logistic regression with hospital random intercept, adjusting for patient, operation, hospital, and community characteristics. Secondary analyses stratified by operation urgency and by insurance type in an all-payor cohort. ResultsOf 115,527 Medicaid enrollees, 17.2% had non-English language preference (n = 19,881), 66% were female (n = 73,653), and 40% were Hispanic/Latino (n = 45,541). Patients with non-English language preference experienced fewer postoperative emergency department visits (non-English language preference: 13.5%, English preference: 17.9%, P < .001) and readmissions (non-English language preference: 7.5%, English preference: 8.5%, P < .001), which persisted in adjusted models (adjusted odds ratio emergency department, 0.80, 95% confidence interval, 0.77–0.85; readmissions: adjusted odds ratio, 0.86, 95% confidence interval, 0.80–0.92). Non-English language preference was associated with fewer emergency department visits after elective (adjusted odds ratio, 0.80; 95% confidence interval, 0.73–0.88) and urgent/emergent surgery (adjusted odds ratio, 0.80; 95% confidence interval, 0.75–0.85) but not readmissions after elective surgery (adjusted odds ratio, 0.89; 95% confidence interval, 0.78–1.01). This pattern was only observed for Medicaid and not other insurance types. ConclusionPatients with non-English language preference who receive Medicaid have fewer postoperative emergency department visits and readmissions, even after urgent surgery. Our findings suggest that patterns of health care seeking after surgery vary by patient language, and investigating explanatory mechanisms is needed.

Surgical outcomes in penile fractures: A single center experience in China

IntroductionPenile fracture is an uncommon urological emergency resulting from tunica albuginea rupture during penile erection. It is a rare condition requiring urgent surgery. Despite immediate surgical repair, the patients' erectile functions may still be impacted by penile fracture. This study aims to investigate the efficacy of surgical repair in penile fractures and its impact on erectile function. MethodsOur cohort was composed of patients diagnosed with penile fractures and received surgical repair from September 2014 to August 2022 in Peking University First Hospital. Penile color Doppler ultrasound confirmed the diagnosis. Surgical exploration was conducted, and postoperative complications were evaluated during follow-up. Erectile function was assessed using the International Index of Erectile Function-5 (IIEF-5) score. Univariate analysis was conducted employing the chi-square test, t-test, and Mann-Whitney U test to identify factors that may impact postoperative erectile function. Furthermore, multivariate analysis was conducted using logistic regression and linear regression to determine the independent risk factors influencing postoperative erectile function. ResultsA total of 58 patients were enrolled in our study. The majority of injuries (69.0 %, 40/58) resulted from vigorous sexual intercourse. Most of the patients (69.0 %, 40/58) presented within 24 h. Sixteen patients (27.6 %) presented with concomitant urethral injury. The median size of the tunical tear was 1.5 (IQR, 1.0–2.0) cm. Presentation delay correlated significantly with the difference in IIEF-5 score before and after surgery, with corresponding p values of 0.028. Urethral injury correlated significantly with postoperative erectile dysfunction (ED), postoperative IIEF-5 score, and the difference in IIEF-5 score before and after surgery, with corresponding p values of 0.002, 0.004, and 0.002, respectively. ConclusionsTo conclude, surgical repair of penile fracture provides good functional results with few morbidities and urethral injury may adversely affect postoperative erectile function after penile fracture repair.

Hepatic compartment syndrome, a rare complication after any liver insult or liver transplantation: Three case reports and literature review.

Hepatic compartment syndrome (HCS) is a rare but life-threatening entity that consists of a decreased portal flow due to intraparenchymal hypertension secondary to subcapsular liver hematoma. Lethal liver failure can be observed. We report three cases, and review the literature. A 54-year-old male was admitted for extensive hepatic subcapsular hematoma after blunt abdominal trauma. Initially, he underwent embolization of the hepatic artery's right branch, after which he presented clinical deterioration, major cytolysis (310 times the upper limit of normal [ULN]), and liver failure with a prothrombin time (PT) at 31.0%. A 56-year-old male underwent liver transplantation for acute alcoholic hepatitis. On postoperative day 2, he presented a hemorrhagic shock associated with deterioration of liver function (cytolysis 21 ULN, PT 39.0%) due to extensive hepatic subcapsular hematoma. A 59-year-old male presented a hepatic subcapsular hematoma five days after a cholecystectomy, revealed by abdominal pain with liver dysfunction (cytolysis 10 ULN, PT 63.0%). All patients ultimately underwent urgent surgery for liver capsule excision, hematoma evacuation, and liver packing, if needed. The international literature was screened for this entity. These three patients' outcomes were favorable, and all were alive at postoperative day 90. The literature review found 15 reported cases. HCS can occur after any direct or indirect liver trauma. Surgical decompression is the main treatment, and there is probably no place for arterial embolization, which may increase the risk of liver necrosis. A 13.3% mortality rate is reported. HCS is a rare complication of subcapsular liver hematoma that compresses the liver parenchyma, and leads to liver failure. Urgent surgical decompression is needed.

Neuraxial anesthesia for non-neurological emergency surgery in a patient with acute ischemic stroke: a case report

BackgroundThe recent guidelines recommend delaying elective non-neurological surgery after an index stroke, but there is a lack of consensus regarding emergency surgery in patients with a recent stroke. Impaired cerebral autoregulation and altered baroreceptor function elevate the risk of recurrent stroke in this group. Moreover, the impact of anesthesia type (general vs. regional) for non-cardiovascular, non-neurological surgery in patients with an index stroke remains inconclusive.Case presentationA 67-year-old male with an acute mild ischemic stroke underwent emergency surgery for an obstructed right-sided direct inguinal hernia under combined spinal-epidural anesthesia. Pre-operative assessment showed stable hemodynamics, and perioperative measures were taken to ensure stable blood pressure. Neuraxial anesthesia was employed successfully, and the patient remained hemodynamically stable throughout the surgery and postoperative period. No neurological deficits were observed post-surgery, and follow-up up to 3 months revealed no cognitive impairment or neurological decline.ConclusionsNeuraxial anesthesia can be considered for patients with acute mild strokes requiring urgent non-neurological surgery, provided they are hemodynamically stable and without coagulopathy. However, the choice of anesthesia should be individualized based on factors such as neurological status, stroke severity, coagulation, and existing disabilities. This case highlights the importance of a personalized approach to anesthesia in emergency surgery for stroke patients.

Abdominal Cocoon: a rare case of small bowel obstruction, a case report

Sclerosing encapsulating peritonitis (SEP), or abdominal cocoon syndrome (ACS), is an uncommon disorder marked by a thick fibrotic membrane that completely or partially envelops the small bowel. For surgeons, preoperative diagnosis is difficult and challenging. The majority of documented, diagnosis were made during a laparotomy. We present a case of SEP that was diagnosed preoperatively. The patient had a complete small bowel obstruction that necessitated urgent surgery. We review the literature and discuss the causes, clinical manifestation, and management of the condition.

Cancer masquerading as an intussusception: Experience at tertiary care rural hospital

One segment of the intestine telescopes into another, resulting in obstruction or intestinal ischemia. A pathological lead point, such as a tumor, causes the disease. A pathologic lead point in the lumen, wall, or outside the wall can cause adult intussusception (AI). Retrospective case series of eight patients diagnosed with AI over 18 years in a tertiary rural tertiary a decade (2010-2020). Out of 8 AI cases6 were women, and 2 were men. The median age at diagnosis was 44 years. AI was verified by USG (25%), with CT scan being (100%) sensitivity preoperatively. AI distribution (2 in the small bowel, four at the ileocecal region, and 2 in the colon). The most commonly reported presenting symptom was abdominal pain. (8/8,100%). 75% (6/8) of patients underwent urgent surgery after presenting with acute intestinal obstruction. At the same time, two cases underwent elective surgery. Out of them, five cases were malignant (adenocarcinoma) (62.5%), and three cases were benign tumors (37.5%). (Inflammatory myofibroblastic tumor, a Meckel’s diverticulum, and appendicitis). Due to the lack of specific symptoms, the diagnosis of AI by clinicians and surgeons is frequently missed out. When dealing with acute abdominal pain and signs of bowel obstruction, it's important to consider this less common diagnostic possibility because intussusception is a surgical emergency with high mortality rates in the case of delayed treatment. A surgical approach must be practiced to avoid missing underlying causes like neoplasm.

Word of caution: early life-threatening complication linked to pulmonary flow restrictors.

A 2-month-old female (3.4 kg, 50 cm) with Down syndrome and left-to-right shunting congenital heart defects underwent an unsuccessful transcatheter ductal closure, followed by bilateral implantation of manually modified microvascular plugs (MVP-9Q) from Medtronic (Minneapolis, MN, USA), used as pulmonary flow restrictors. Post-procedure, she developed febrile respiratory distress, leading to admission to the intensive care unit. Despite initial improvement, she was readmitted with respiratory syncytial virus infection, progressing to bilateral pneumonic consolidation. Subsequent complications included pulmonary artery aneurysmal dilatation attributed to pulmonary flow restrictors, which necessitated urgent surgery two months after their implantation. The surgery involved removing the pulmonary flow restrictors and repairing the injuries to the pulmonary artery, followed by management with extracorporeal support and targeted antibiotics. The patient recovered over 12 months.

Early Hip Fracture Surgery in Patients Taking Direct Oral Anticoagulants Improves Outcome.

Background/Objectives: The increasing numbers of already endemic hip fractures in the elderly taking anticoagulants is a growing concern for daily surgical practice. Ample evidence demonstrates decreased morbidity and mortality in the general population when surgery is performed at the earliest possibility. Direct anticoagulants are relatively new drugs that can cause increased perioperative bleeding. Current guidelines propose stopping the drug to allow for elimination before performing elective surgery. Optimal management in urgent hip surgery is presently based on expert opinion with arbitrary cut-offs. In this study, we investigated whether patients taking direct anticoagulants would benefit from early surgical treatment, regardless of the timing since last intake. Methods: A total of 340 patients were included in the analysis, of which 59 took direct anticoagulants. The primary outcomes were time to surgery, postoperative transfusion rate, postoperative hemoglobin decrease, length of postoperative in-hospital stay (LOPS), revision rate, and complication rate (medical and surgical). Results: Our findings showed that the anticoagulated group was fit for discharge earlier when operated on within 24 h (p = 0.0167). Postoperative transfusion and medical complication rate tended to be lower when the operation was performed earlier. Revision rate due to hematomas were higher in the direct anticoagulant group without a relationship to time to surgery. Simple linear regression could not determine a relationship between postoperative hemoglobin change and time to surgery. Conclusions: We suggest that directly anticoagulated patients needing hip fracture surgery must be considered for early surgery.

Management of Ileosigmoid Knotting: A Literature Review

Ileosigmoid knotting (ISK) is a rare double-segment intestinal obstruction form. Urgent surgery is the unique solution in the management of ISK. In surgical treatment, detorsion alone is generally used in patients with viable bowel, while cases with gangrenous bowel require resection. ISK recurrence is uncommon. However, due to the recurrence risk of sigmoid volvulus, the role of recurrence-reducing procedures is unclear. In this review, urgent treatment of ISK as well as the techniques and patient selection criteria of recurrence-reducing management are discussed.

Effect of time of day on outcomes in elective surgery: asystematic review.

The timing of elective surgery could affect clinical outcome because of diurnal rhythms of patient physiology as well as surgical team performance. Waiting times for elective surgery are increasing in many countries, leading to increasing interest in undertaking elective surgery in the evening or at night. We aimed to systematically review the literature on the effect of the timing of elective (but not urgent or emergency) surgery on mortality, morbidity and other clinical outcomes. We searched databases for relevant studies combining the terms 'circadian rhythm' and 'anaesthesia/surgery'. Additional relevant articles were found by hand-searching the references. All studies were screened for bias. Included studies examined daytime vs. evening/night-time surgery, morning vs. afternoon surgery, multiple timeslots or used time as a continuous variable. Nineteen retrospective cohort studies, one prospective cohort study and one randomised controlled trial were included (n = 798,914). Evening/night-time elective surgery was associated with a higher risk of mortality when compared with daytime procedures in three studies (n = 611,230), with odds ratios (95%CI) for mortality ranging from 1.35 (1.16-1.56) to 3.98 (1.54-10.30), while no differences were found in three other studies (n = 142,355). No differences were found for morning vs. afternoon surgery (four studies, n = 3277). However, most studies had a low quality of evidence due to their retrospective nature and because not all studies corrected for patient characteristics. Moreover, the studies were heterogeneous in terms of the reported time slots and clinical outcomes. We found that evening/night-time elective surgery is associated with a higher risk of mortality compared with daytime surgery. However, the quality of evidence was graded as low, and thus, future prospective research should publish individual patient data and standardise outcome measures to allow firm conclusions and facilitate interventions.

Decreased Long-Term Survival of Patients With Newly Diagnosed Cancer Discharged Home After Unplanned ICU Admission: A Prospective Observational Study.

To compare the 18-month survival between patients with newly diagnosed cancer discharged home after early unplanned ICU admission and those without early unplanned ICU admission; we also evaluated the frequency and risk factors for early unplanned ICU admission. Observational study with prospectively collected data from September 2019 to June 2021 and 18 months follow-up. Single dedicated cancer center in São Paulo, Brazil. We screened consecutive adults with suspected cancer and included those with histologically proven cancer from among 20 highly prevalent cancers. None. The exposure was early unplanned ICU admission, defined as admission for medical reasons or urgent surgery during the first 6 months after cancer diagnosis. The main outcome was 18-month survival after cancer diagnosis, and the main analysis was Cox's proportional hazards model adjusted for confounders and immortal time bias. Propensity score matching was used in the sensitivity analysis. We screened 4738 consecutive adults with suspected cancer and included 3348 patients. Three hundred twelve (9.3%) had early unplanned ICU admission, which was associated with decreased 18-month survival both in the unadjusted (hazard ratio, 4.03; 95% CI, 2.89-5.62) and adjusted (hazard ratio, 1.84; 95% CI, 1.29-2.64) models. The sensitivity analysis confirmed the results because the groups were balanced after matching, and the 18-month survival of patients with early ICU admission was lower compared with patients without early ICU admission (87.0% vs. 93.9%; p = 0.01 log-rank test). Risk factors for early unplanned ICU admission were advanced age, comorbidities, worse performance status, socioeconomic deprivation, metastatic tumors, and hematologic malignancies. Patients with newly diagnosed cancer discharged home after early unplanned ICU admission have decreased 18-month survival compared with patients without early unplanned ICU admission.

Vitamin K Antagonist Reversal for Urgent Surgery Using 4-Factor Prothrombin Complex Concentrates

Millions of people take vitamin K antagonists (VKAs). Some people who need urgent surgical procedures require rapid VKA reversal to prevent excessive intraoperative bleeding. To evaluate the hemostatic noninferiority of an investigational 4-factor prothrombin complex concentrate (4F-PCC) to a control 4F-PCC for rapid VKA reversal before urgent surgery. This phase 3, double-blind, noninferiority randomized clinical trial (LEX-209) was conducted in 24 hospitals in the US, Russia, Georgia, Belarus, Ukraine, and Romania from June 7, 2017, through November 8, 2021; the study was stopped in February 2022. Participants were adult patients taking VKA who had an international normalized ratio (INR) of 2 or higher and needed urgent surgery with a substantial bleeding risk (≥50 mL). Patients were randomized 1:1 to a single infusion of either the investigational 4F-PCC or the control 4F-PCC. Data analysis followed intention-to-treat and per-protocol approaches. Single intravenous infusion was dosed by body weight and baseline INR. A dose of 25, 35, or 50 IU/kg of investigational 4F-PCC or control 4F-PCC was administered for baseline INR of 2 to less than 4, 4 to 6, or over 6, respectively. The primary end point was hemostatic efficacy at surgery end. An independent adjudication board, blinded to the 4F-PCC treatment allocation, assessed hemostatic efficacy using an objective 4-point scale. A total of 208 patients (median [range] age, 67.5 [31-92] years; 118 males [56.7%]) received the investigational (n = 105) or the control (n = 103) 4F-PCC. The median (range) dose was 25 (16-50) IU/kg in the investigational group and 25 (15-50) IU/kg in the control group, with a median (range) infusion time of 12 (8-50) minutes and 13 (7-30) minutes and a median (range) time from infusion to surgery start of 1.42 (0.25-15.25) hours and 1.50 (0.42-18.50) hours, respectively. Baseline median (range) INR was 3.05 (1.97-21.10) in the investigational group and 3.00 (2.00-11.30) in the control group. In the intention-to-treat analysis, the investigational 4F-PCC was noninferior to the control 4F-PCC, resulting in effective hemostasis in 94.3% of patients vs 94.2% of patients (proportion difference, 0.001; 95% CI, -0.080 to 0.082; P < .001), meeting the prespecified noninferiority margin of 0.15. An INR of 1.5 or lower at 30 minutes after infusion occurred in 78.1% of patients in the investigational group vs 71.8% of patients in the control group (proportion difference, 0.063; 95% CI, -0.056 to 0.181). Thrombotic events (2.9% vs 0%, respectively) and mortality (4.8% vs 1.0%, respectively) were no different than expected for 4F-PCC use. One patient in each treatment group discontinued due to adverse events (cardiac disorders unrelated to 4F-PCC). This randomized clinical trial found that the investigational 4F-PCC was hemostatically noninferior to the control 4F-PCC for rapid VKA reversal in patients needing urgent surgery with considerable bleeding risk; the safety profile of these two 4F-PCCs was similar. These results support the investigational 4F-PCC as a therapeutic option for surgical patients requiring rapid VKA reversal. ClinicalTrials.gov Identifier: NCT02740335.

Multiple aortic valve papillary fibroelastomas causing recurrent cerebrovascular events

IntroductionPapillary fibroelastomas (PFE) are benign, rare primary cardiac tumors often discovered incidentally during cardiac imaging or as part of a workup for thromboembolic or obstructive events. We present a case of multiple PFE on the aortic valve's right coronary and non-coronary leaflets, presenting as recurrent cerebrovascular events managed by resection with valve preservation. Case SummaryA 53-year-old male presented with an acute right frontal cerebrovascular accident and a history of recurrent transient ischemic attacks. A transesophageal echocardiogram (TEE) revealed a 10 × 8 mm mass on the right coronary cusp of the aortic valve. Differential diagnosis included PFE versus thrombus. Following a neurology evaluation, the patient was anticoagulated and scheduled for urgent cardiac surgery. During surgery, an 8 × 7 mm mass was sharply excised from the right coronary leaflet's anterior surface. Further examination revealed additional masses: a 3 mm mass on the underside of the right coronary leaflet, a 2 mm mass on the non-coronary leaflet, and another 2 mm mass on its underside. All masses were excised, and pathology confirmed the diagnosis of PFE. The patient's post-operative course was unremarkable, and a pre-discharge transthoracic echocardiogram (TTE) demonstrated complete removal of the aortic valve masses with normal ventricular and aortic valve function. DiscussionPFE are rare benign cardiac tumors with a significant risk of thromboembolic or obstructive events, including stroke. Grossly, they are attached to the endocardium by a short fibrous pedicle with multiple papillary fronds resembling a sea anemone. More than 95 % originate from the left heart, most commonly affecting the aortic valve. Diagnosis is primarily through echocardiography, with TEE being more sensitive than TTE. Surgical excision is curative, offering an excellent long-term prognosis. ConclusionAll patients with suspected embolic cerebrovascular events should undergo echocardiographic evaluation to assess for potential cardiac etiologies. Surgical resection of PFE results in uniformly excellent clinical outcomes, with aortic valve preservation achievable in over 98 % of cases.

Clostridioides Difficile Infection Presenting with Fulminant Colitis

Abstract Clostridioides difficile infection (CDI) is a common hospital-acquired infection, typically presenting with watery diarrhea and colitis. Most cases are managed with clinical support and antibiotics. Recently, more virulent strains have been associated with life-threatening infections. Surgery plays a role for complicated cases failing clinical treatment or with complications, such as bowel perforation and peritonitis. The present study reports the case of a 62-year-old female with CDI and fulminant colitis requiring urgent surgery. Surgeons should be aware of this presentation and involved early in the care of these patients, as clinical deterioration can occur very rapidly.
