Budd Chiari Syndrome: Radiological Aspects of the Disease Pertaining to Infertility and Role of Interventional Radiology in Successful Conception

PurposeTo study the association of infertility in patients with Budd Chiari syndrome, radiological aspects of the disease determining infertility and to see if there are improved chances of conception following radiological intervention. MethodsRetrospective search of the hospital records was done and patients with Budd Chiari syndrome, who underwent radiological intervention between January 2016 till October 2021 were initially included. Patients outside the reproductive age group, unmarried patients, patients who did not attempt conception or attempted for less than 1 year and patients having other causes of infertility were excluded. 90 patients were assessed for presence of primary or secondary infertility using infertility questionnaire. In patients with infertility, conception during 1 year follow-up period following radiological intervention, was assessed. Results146 patients underwent radiological intervention for budd chiari syndrome in the study period. 56 patients meeting the exclusion criteria were excluded from the study and subsequently 90 patients were assessed for infertility. 16.7% (15/90) of our patients with Budd Chiari syndrome had infertility, of which 7 were male, and 8 were female. Infertility is more common in younger age group (mean – 28.8±4.2 years) (p<0.001). In females, presence of pelvic venous congestion on preprocedural imaging showed significant association with infertility(p<0.001). 6 (40%) out of 15 of patients with infertility conceived during a 1year follow-up period after radiological intervention. ConclusionInfertility is a common in patients with Budd Chiari syndrome, with a prevalence of 16.7%. Pelvic venous congestion is associated with women having infertility. Radiological interventions play important role in management of Budd Chiari and may help to overcome infertility in these patients.

Erratum: Role of Interventional Radiology in the Management of Liver Transplant Complications in Children

Erratum: Role of Interventional Radiology in the Management of Liver Transplant Complications in Children

Role of Interventional Radiology in the Management of Liver Transplant Complications in Children

AbstractLiver transplantation (LT) is a common solid organ transplant in the pediatric population. The common indications for LT, as well as its complications, differ between adults and children. This difference necessitates unique pediatric interventional radiology (IR) interventions. This article focuses on unique vascular complications occurring post-pediatric LT and highlights the importance of IR in their management. It explores IR's involvement in the workup of patients' pre-LT and management of complications following portosystemic shunts. We discuss advantages and disadvantages of different access routes as well as the prevalence, clinical picture, diagnosis, and management of complications after pediatric LT. These complications encompass portal vein stenosis, portal vein thrombosis, hepatic artery stenosis, hepatic artery thrombosis, hepatic artery pseudoaneurysm, arterioportal fistula, hepatic vein stenosis, and inferior vena cava stenosis. The choice of endovascular technique for a clinical indication depends on vascular anatomy, time since LT, and patient-specific factors. Transsplenic access is a useful alternative to transhepatic or transjugular access. The decision to place a stent in a child is influenced by the expected growth of the child and risk of focal narrowing at stent edge (because of recipient growth). Technical challenges in pediatric patient management, including uncooperative patients and sedation issues, must be considered. Pediatric LT complications can present with significant challenges in the posttransplant care of recipients and may lead to serious morbidity and graft failure if not managed effectively. IR techniques like balloon angioplasty, stent placement, thrombolysis, and embolization have demonstrated success in treating these complications, improving patient outcomes, and reducing long-term morbidity and mortality. By enhancing the understanding of medical practitioners and interventional radiologists about complex vascular complications, this article aims to contribute to better posttransplant care and improved outcomes for LT in pediatric populations. Continued collaboration between specialties and research will advance the field of pediatric LT and IR, to create even more effective treatment strategies.

Role of Interventional Radiology in Managing Primary and Metastatic Breast Cancer.

Percutaneous image-guided locoregional therapies are emerging in the treatment of primary and metastatic breast cancer. Cryoablation has emerged as the dominant ablative approach as an alternative to surgery for primary breast cancer in patients who do not wish to have surgery or are poor surgical candidates. Cryoablation is well tolerated and provides excellent local control and cosmesis. Thermal ablation may also be used in the treatment of oligometastatic breast cancer, allowing patients to achieve long disease-free intervals. Transarterial therapies have been studied in the treatment of oligoprogressive hepatic metastasis, though further supportive data would be helpful to demonstrate its efficacy.

Role of interventional radiology in obstetrics and gynaecology: a clinical review of an experience in a quaternary care centre.

The study aims to equip both Obstetricians and Gynaecologists with the knowledge of clinical conditions that will benefit from interventional radiology, equipment and materials that are commonly used, benefits, complications and the side effects of these techniques. It was a single-centre, retrospective cohort study with examples from hospital practice during the period of 2015 to 2021, acquired through computerised database including all obstetrics and gynecological cases in which interventional radiology techniques were used. No statistical analysis of data was applicable as it was a single-centre retrospective analysis of cases. We had a total of 35 cases, including but not limited to placenta accreta spectrum disorders, fibroid, pelvic congestion syndrome and arteriovenous malformation who underwent various interventional radiological procedures ranging from embolization of uterine artery, peripheral angiography, embolization, and internal iliac artery balloon placement to ovarian vein embolization and coil insertion. Increased collaborative efforts between interventional radiology and gynaecology would allow patients to be fully informed on the complete spectrum of surgical and nonsurgical treatment options available to them.

Role of Interventional Radiology (IR) in vascular emergencies among cirrhotic patients.

Gastrointestinal hemorrhage remains one of the most common causes of morbidity and mortality among patients with liver cirrhosis. Mostly, these patients bleed from the gastroesophageal varices. However, nonvariceal bleeding is also more likely to occur in these patients. Because of frequent co-existing coagulopathy, cirrhotics are more prone to bleed from a minor vascular injury while performing percutaneous interventions. Ultrasound-guided bedside vascular access is an essential procedure in liver critical care units. Transjugular portosystemic shunts (TIPS) with/without variceal embolization is a life-saving measure in patients with refractory variceal bleeding. Whenever feasible, balloon-assisted retrograde transvenous obliteration (BRTO) is an alternative to TIPS in managing gastric variceal bleeding, but without a risk of hepatic encephalopathy. In cases of failed or unfeasible endotherapy, transarterial embolization using various embolic agents remains the cornerstone therapy in patients with nonvariceal bleeding such as ruptured hepatocellular carcinoma, gastroduodenal ulcer bleeding, and procedure-related hemorrhagic complications. Among various embolic agents, N-butyl cyanoacrylate (NBCA) enables better vascular occlusion in cirrhotics, even in coagulopathy, making it a more suitable embolic agent in an expert hand. This article briefly entails the different interventional radiological procedures in vascular emergencies among patients with liver cirrhosis.

Preoperative Transcatheter Arterial Embolization for Spontaneous Rupture of Huge Amebic Liver Abscess with Massive Intraperitoneal Hemorrhage

An 18-year-old male developed a huge liver abscess with severe anemia over the course of 2 weeks. Abdominal contrast enhanced computed tomography showed ruptured huge liver abscess in the right liver lobe with signs of active hemorrhage (contrast extravasation). Serology examination confirmed amoeba as the suspected pathogen of cause. Angiography was performed followed by transcatheter arterial embolization to localize and control the hemorrhage. Embolization using a combination of polyvinyl alcohol and gelfoam successfully controlled the active hemorrhage. Exploratory laparotomy was performed to evacuate and debride the huge abscess. Metronidazole was given and showed good results. Huge liver abscess size is a predictor of conservative management failure and requires a gradual step-up intervention. The purpose of this paper is to explain the importance of imaging in detecting liver abscess and active hemorrhage along with the role of interventional radiology in this case.

Interventional Radiology Management of Advanced Schistosomiasis: State of the Art

AbstractAdvanced schistosomiasis is an infectious disease, endemic in some regions, with long-term implications for patient care. It can be associated with conditions such as portal hypertension, variceal hemorrhage, chronic hepatic encephalopathy, and hepatocellular carcinoma. In this article, an overview of the most recent data about the role of interventional radiology in the management of these conditions will be presented, as well as the authors' experience on interventional management of schistosomiasis patients.

Pediatric Renovascular Hypertension: A Pediatric Interventional Radiologist's Perspective.

Renovascular hypertension (RVH) contributes close to one-fourth of the secondary etiologies of hypertension in children and a delay in diagnosis can result in adverse clinical outcomes. RVH in children is clinically silent with elevations in blood pressure measurements sometimes as its sole manifestation. Only a high index of suspicion by the clinician can prompt its detection. Despite the availability of other imaging modalities like ultrasound, computed tomography, and magnetic resonance imaging, digital subtraction angiography is still considered the gold standard to make a diagnosis of RVH. Angioplasty is considered the treatment of choice in appropriately selected patients. In this article, we shall focus on the various imaging findings, and management of RVH in children, which requires a multidisciplinary approach with a special focus on the role of interventional radiology.

Role of interventional radiology in the management of iatrogenic urinary tract injury: the factors affecting the outcome

To evaluate the efficacy of interventional radiological (IR) procedures in iatrogenic urinary tract injury and investigate the factors affecting the outcome. Fifty-eight patients (21 male) with a mean age of 50.3 ± 15.8 years referred for iatrogenic urinary tract injury were enrolled in this study. Technical success was defined as (i) successful placement of a nephrostomy catheter within the renal pelvis and/or (ii) successful antegrade ureteral stent placement (double J stent) between the renal pelvis and bladder lumen. Complete resolution was defined as maintained ureteral patency without an external drain and ureteral stent. The factors that may affect complete resolution [ureteral avulsion, ureterovaginal fistula (UVF), history of malignancy/radiotherapy, and time to IR management] were also investigated. The receiver operating characteristic analysis was performed to estimate the cut-off time point for the IR management timing affecting complete resolution. The technical success rate for nephrostomy and ureteral stent placement was 100% (n = 58/58) and 78% (n = 28/36), respectively. In 14 patients, non-dilated pelvicalyceal systems were evident. In 18 patients, no further intervention after percutaneous nephrostomy was performed due to (i) poor performance status (n = 6) and (ii) reconstruction surgery upon clinicians' and/or patients' request (n = 12). Reconstruction surgery was required in 11 of the remaining 40 patients due to failure of percutaneous treatment (n = 11/40, 27.5%). In six of the patients, ureteral stents could not be removed due to the development of benign ureteral strictures (n = 6/40, 15%). Our complete resolution rate was 57.5% (n = 23/40). Age, gender, type of surgery (endoscopic or open), side and location of the injury did not statistically affect the complete resolution rate. The presence of ureteral avulsion, history of malignancy and radiotherapy individually or in combination significantly affected the complete resolution rate negatively. The presence of UVF also had a negative effect on the complete resolution rate; however, it did not reach statistical significance. Delayed intervention was also a significant factor related to lower complete resolution. The optimal cut-off point of the time interval for favorable clinical outcome was found to be 0–19th day following the surgery. IR procedures are safe and effective in the management of iatrogenic urinary tract injuries. Antegrade ureteral stenting should be performed as soon as possible to establish ureteral integrity without the development of stricture.

Role of interventional radiology in upper abdominal cancer pain management

BackgroundThe major indication for celiac plexus block is abdominal pain that is nonresponsive to analgesic interventions; often these patients are nonresponsive to high-dose opioid therapies. One of the most common indications for the celiac plexus block is the treatment of abdominal pain associated with pancreatic cancer.Aim of the workThe differences between two techniques (ultrasound and fluoroscopy guided) are highlighted in terms of effectiveness by means of a Visual Analog Scale (VAS), a percentage reduction in daily morphine consumption and any complications are recorded and evaluated at the time of implementation of each technique from start to finish.ResultsThrough the data that have been recorded and statistically analyzed, we found that the mean values of VAS were decreased in the two groups, and there was statistically significant difference between ultrasound and fluoroscopy groups.ConclusionsIt is noticeable and good in conducting this research that there are no major complications that include a large space on the study sample, despite the presence of some minor with no significant differences between ultrasound and fluoroscopy groups. This effective celiac block, regardless of the technique used, produced immediate analgesics that permitted significant opioid decrease in the study sample with a significant improvement in the unwanted adverse effects on account of opioids.

Role of interventional radiology in surgical diseases of breast.

Since the publication of the first imaging-guided wire localisation technique, the art of breast treatments has made great strides. Radiologists like Hall, Frank, Kopans, DeLuca, and Homer were all the pioneers in innovative breast interventional radiology field. Their approaches and gadgets for enhancing surgical outcomes in cases with breast diseases aided progress in the discipline and have withstood the ravages of time. Many of their methods are still in use. We are all standing together at the beginning of a new chapter in medicine. Cost effectiveness, comparative effectiveness studies, and an older population are all causing clinicians to reconsider what they perform. Similarly, we are now united on a global scale. The studies described in the current narrative review relate to multiple nations around the world. Breast cancer is a worldwide health problem. With the expansion of technological advances, as well as the apparent ease of worldwide travel, we must all collaborate to improve the outcome in the battle against breast cancer.

Placenta accreta spectrum disorders clinical practice guidelines: A systematic review.

To objectively assess the quality of the published clinical practice guidelines (CPGs) on the management of pregnancies complicated by placenta accreta spectrum (PAS)disorders. MEDLINE, Embase, Scopus, and ISI Web of Science databases were searched. The following aspects related to the management of pregnancies with suspected PAS disorders were evaluated: risk factors for PAS, prenatal diagnosis, role of interventional radiology and ureteral stenting, and optimal surgical management. The assessment of risk of bias and quality assessment of the CPGs were performed using the (AGREE II) tool (Brouwers et al., 2010). To define a CPG as of good quality we adopted a cut-off score >60%. Nine CPGs were included. Specific risk factors for referral were assessed by 44.4% (4/9) of CPGs, mainly consisting in the presence of placenta previa and a prior cesarean delivery or uterine surgery. About 55.6% of CPGs (5/9) suggested ultrasound assessment of women with risk factors for PAS in the second and third trimester of pregnancy and 33.3% (3/9) recommended magnetic resonance imaging (MRI); 88.9% (8/9) of CPGs recommended cesarean delivery at 34-37 weeks of gestation. There was not generally consensus on the use of interventional radiology and ureteral stenting before surgery for PAS. Finally, hysterectomy was the recommend surgical approach by 77.8% (7/9) of the included CPGs. Most of the published CPGs on PAS are generally of good quality. There was general agreement among the different CPGs on PAS as a regard as risk stratification, timing at diagnosis and delivery but not on the indication for MRI, use of interventional radiology and ureteral stenting.

Introduction to interventional radiology's role in palliative care for children with cancer: A COG Diagnostic Imaging Committee/SPR Oncology Committee White Paper.

As palliative care continues to be an area of increasing emphasis in pediatric oncology programs, it is important to raise awareness about minimally invasive, image-guided procedures that can supplement more conventional palliative interventions, such as systemic analgesics, external beam radiation, and locoregional anesthesia. These procedures, when performed for appropriately selected patients, can often facilitate discharge from an inpatient facility, and help patients meet their end-of-life goals. This article specifically discusses three palliative procedures performed by interventional radiologists that can assist pediatric palliative care teams in: (a) percutaneous thermal ablation of painful bone metastases, (b) cryoneurolysis, and (c) tunneled drainage catheter placement for malignant pleural effusions and ascites.

The Role of Interventional Radiology and Management of an Angiography Suite in the Treatment of COVID-19 Patients: Single-Center, 2-Year Experience.

Background and Objectives: Hospital angiography suites with negative-pressure ventilation facilities are challenging to equip. During the COVID-19 pandemic, we aimed to introduce interventional radiology procedures performed on COVID-19 patients and understand management of the angiography suite without a negative-pressure ventilation facility before and after the procedures to prevent the spread of infection. Materials and Methods: Between December 2020 and November 2022, 52 COVID-19 patients underwent interventional radiology procedures in an angiography suite, where no negative-pressure ventilation facility was installed. During the procedure, all staff members wore full personal protection equipment, and after the procedure for the COVID-19-positive patient was completed, the angiography suite was disinfected and entry to the angiography suite was prohibited for 1-3 h. In this angiography suite, procedures for COVID-19 patients and non-COVID-19 patients were performed. Results: A total of 61 interventional radiology procedures were performed in 52 patients with COVID-19. Of 52 patients, 21 underwent procedures under intubation and mechanical ventilation. All procedures were performed according to the guidelines set by the Infection Control Committee of our hospital. No major or minor complications were associated with the procedures. There were no cases of infection among staff members or other non-COVID-19 patients related to procedures on COVID-19 patients. Conclusions: Interventional radiology can play an important role in solving the complications of COVID-19 and the problems caused by patients' underlying diseases. In addition, if accurate guidelines are followed, both COVID-19 and non-COVID-19 patients can undergo procedures in an angiography room without negative-pressure ventilation while preventing infection.

Awareness and Knowledge of Interventional Radiology among Clinical Years Medical Students of Umm Al-Qura University

Background: Although the last few years showed growth in the role of interventional radiology (IR) in treating various conditions, the specialty faces several difficulties including a shortage of interventional radiologists and inadequate awareness among undergraduate students because of the limited exposure during medical school. Therefore, this study aims to evaluate the level of knowledge and awareness of IR among Clinical Years Medical Students of Umm Al-Qura University. Methodology: This was a cross-sectional, survey-based study at Umm Al-Qura University, Makkah, Saudi Arabia, which included 358 medical students. Results: Most of the participants rated their knowledge of IR as either adequate or poor (39.1% each), and 7.3% reported that they knew nothing about IR, while 3.4% responded that they had excellent knowledge of IR. Many of the respondents (58.7%) were not interested in considering a career in IR. Only a few students (10.3%) received elective radiology training. Additionally, 55% thought the correct route for training interventional radiologists was from both surgical and radiological fields, while 36% thought they were only radiologically trained. Conclusion: This study demonstrated that medical students\&amp;apos; knowledge and awareness of IR are poor. This can be improved by rotations, electives, and attendance at IR conferences, which will increase undergraduate awareness and promote IR as a career.

Role of Interventional Radiology in the Management of Vascular Lesions around the Knee Joint: A Series of Four Cases

The soft tissue lesions around the knee range from congenital, traumatic, and vascular to neoplastic in aetiology. The various imaging modalities employed for diagnostic work-up include plain radiographs, ultrasonography, Computed Tomography (CT) scan, and Magnetic Resonance Imaging (MRI). Based on the peculiar imaging findings, the differential diagnosis can be narrowed down; however, the final diagnosis relies on histopathological findings. Some of the highly vascular lesions are arteriovenous malformation, malignant fibrous histiocytoma, haemangiopericytoma, and synovial sarcoma. The abundant neovascularity within these lesions poses a major problem during surgery due to potential blood loss. Presurgical interventional management in the form of endovascular embolisation significantly reduces intraoperative blood loss. Here, four different cases, one of each type, presenting as highly vascular lesions around the knee joint, were successfully managed with endovascular embolisation.
