Showkathali Iqbal, Raiz Iqbal, Faiz Iqbal
The Couinaud's liver segmentation is based on the identification of portal vein bifurcation and origin of hepatic veins. It is widely used clinically, because it is better suited for surgery and is more accurate in localizing and monitoring various intra parenchymal lesions. According to standard anatomy, the portal vein bifurcates into right and left branches; the left vein drains segment II, III and IV and the right vein divides into two secondary branches - the anterior portal vein drains segments V and VIII, and the posterior drains segments VI and VII...

The emerging use of mechanical thrombectomy for acute ischemic stroke treatment focuses on the importance of patient selection. Computed tomography perfusion (CTP) is one of widely used techniques. However, the accuracy and reliability of this modality is in debate among vascular neurologists. We present a case of an 80-year-old man admitted because of acute ischemic stroke. CT angiography demonstrated left proximal M2 occlusion. As CTP demonstrated signs of large ischemic core with no significant penumbra, mechanical thrombectomy was not performed following tPA administration...

BACKGROUND: Interventional radiology and cardiology procedures contribute significantly to the collective dose of radiation exposure from medical interventions. Recent and dedicated studies comparing directly these procedures in term of patient radiation exposure are lacking. Our aim was to compare radiation exposure among different interventional procedures performed under fluoroscopic guidance. METHODS: The RODEO study (NCT: 02972736) is an international observational retrospective multicenter study enrolling all patients undergoing diagnostic or interventional procedures performed by different interventional operators (i...

OBJECTIVES: Hepatocellular carcinoma is the sixth most common cancer worldwide and is the third highest cause of malignancy-related death. Because of its typically late diagnosis, median survival is approximately 6 to 20 months, with 5-year survival of < 12%. Hepatocellular carcinoma typically arises in the background of cirrhosis, with liver transplant regarded as the optimal therapy for selected patients. Initially, orthotopic liver transplant was limited to patients with extensive unresectable tumors, resulting in uniformly dismal outcomes due to high tumor recurrence rates...

BACKGROUND: Compared to permanent inferior vena cava (IVC) filters, higher complication rates occur with long-term use of temporary IVC filters. We aimed to identify patient clinical factors at the time of placement that could predict failure to remove a temporary IVC filter. METHODS: A retrospective review was performed of both vascular surgery and interventional radiology prospective databases between December 2008 and December 2013. We analyzed a total number of 1,024 consecutive, temporary IVC filters stratified by whether retrieval was attempted or made permanent...

Complications related to percutaneous biliary tract interventions (PBTIs) can range from access site discomfort to life-threatening vascular complications. These complications are relatively uncommon, and most of them are self-limiting. However, major complications for which an increased level of patient care and/or a prolonged hospital stay are required and that may lead to death-albeit rarely-can occur. Some of the most common complications related to PBTI include pain, infection, bile leakage, and catheter blockage...

The increasing incidence of morbidly adherent placenta (MAP) is placing women at a higher risk of life-threatening massive hemorrhage. The involvement of interventional radiology to manage this complex condition by performing prophylactic iliac artery balloon occlusion has been reported recently. However, the effectiveness and safety of this technique have not been fully determined. Here we report the case of a 25-year-old woman with placenta increta with preemptive bilateral internal iliac artery balloons who had external iliac artery thrombosis detected by computed tomography angiography (CTA) 72 h post cesarean section...

 The prevalence of peripheral artery disease (PAD) is continuously increasing. In addition, the treatment of PAD has changed substantially over the last decades. Novel treatment modalities and diagnostic tools were developed and endovascular therapy was established as a first-line therapy. In consequence, vascular medicine has become an interdisciplinary field, involving different specialties such as internal medicine/cardiology, internal medicine/angiology, vascular surgery, and (interventional) radiology...

Erectile dysfunction (ED) or impotence is estimated to affect around 20-30 million men in the United States (Rhoden et al, 2002). Vascular etiology is purported to be the most prevalent cause of ED in the elderly population, with venogenic ED being the most common subtype (Shafik et al, 2007; Rebonato et al, 2014). A patient, who developed severe venogenic ED, was referred to interventional radiology after ineffective pharmaceutical treatments. Selective embolization of bilateral external and internal pudendal veins was performed through accessing the deep dorsal vein of penis...
