We describe a 36-year-old woman who presented to our facility after sustaining a gunshot wound to the epigastric region. The gunshot resulted in injury to the left lobe of the liver and the twelfth thoracic vertebral body as well as in a through-and-through injury to the abdominal aorta at the level of the celiac axis. The vascular injury was managed successfully by placement of a thoracic stent graft with coverage of the celiac axis. This case demonstrates the feasibility of managing this uncommon injury with endovascular techniques...

Stents are ubiquitously utilized in coronary and peripheral arterial disease. Interventional nephrologists, however, place stents in the venous outflow of the arteriovenous access. Stenosis is the predominant pathology that causes access dysfunction and will ultimately lead to thrombosis if uncorrected. Angioplasty and stent deployment are the current techniques available to combat stenosis. From initial bare metal stainless steel stents, the current generations of stents used are predominately covered nitinol stents...

The evaluation and management of patients with abdominal vascular trauma or injury requires immediate and effective decision-making in these unfavorable circumstances. The majority of these patients arrive at trauma centers in profound shock, secondary to massive blood loss, which is often unrelenting. Moreover, ischemia, compartment syndrome, thrombosis, and embolization may also be life threatening and require immediate intervention. To minimize the risk of these potentially lethal complications, early understanding of the disease process and emergent therapeutic intervention are necessary...

Aorto-enteric fistulae pose a challenging negative outcome of aortic intervention. Treatment involves graft excision, and recently, more enthusiasm has met in situ revascularization over extra-anatomic bypass. This has been traditionally performed through the transperitoneal approach via a midline abdominal incision. We propose an exclusively total retroperitoneal technique in managing this complication with regard to both the vascular and alimentary tract technical aspects of the procedure. This involves exclusion and bypass of the affected segment followed by en-mass resection of the affected segment with the duodenum, and finally, bowel anastomosis...

OBJECTIVE: In the treatment of an infected aorta, open repair and replacement with a rifampin-impregnated Dacron vascular graft decrease the risk of prosthetic graft infections, with several protocols available in the literature. We hypothesize that the same holds true for endovascular aneurysm repair, and after studying and optimizing rifampin solution concentration and incubation period to maximize the coating process of rifampin on Dacron endovascular stent grafts (ESGs), we propose a rapid real-time perioperative protocol...

BACKGROUND: Neurofibroblastoma (NF) or Von Recklinghausen disease, is an autosomal dominant disorder affecting one in 3000 individuals. Cardinal features of NF include multiple café-au-lait macules, benign neurofibromas, and iris hamartomas. Albeit less common, vascular lesions of medium and large-sized arteries and veins are a well-recognized complication, which can lead to fatal consequences such as rupture. METHOD: A systematic review was conducted as per the Preferred Reporting Instructions for Systematic Reviews and Meta-analysis (PRISMA) guidelines utilizing PubMed, EMBASE, and Cochrane databases...

BACKGROUND: Surgical repair of aortic arch pathology is complex and associated with significant morbidity and mortality. Alternative approaches have been developed to reduce these risks, including the use of thoracic stent-grafts with fenestrations or in combination with bypass procedures to maintain supra-aortic trunk blood flow. Branched stent-grafts are a novel approach to treat aortic arch pathology. METHODS: Consecutive patients with aortic arch disease presenting to a single university hospital vascular centre were considered for branched stent-graft repair (October 2010 to January 2017)...

OBJECTIVE/BACKGROUND: Since the late 1950s, major advances in vascular surgical practice have been closely associated with the introduction of novel vascular implants. These devices have been constructed from a variety of materials and have been designed to be implanted in several different ways. Despite a rigorous regulatory process, regular failures continue to be observed. A systematic review of the literature and of the Geprovas registry was performed in order to improve understanding of the failures...

PURPOSE: To report the endovascular treatment of a spontaneous iliac artery dissection (IAD) involving iliac bifurcation, complicated by a type B intramural aortic hematoma (IMH). CASE REPORT: A 38-year-old female patient came to our institution referring an acute ascending back pain. The angioCT-scan showed the presence of a retrograde right IAD with entry tear at the iliac bifurcation and a concomitant aortic IMH. After hypogastric embolization with a vascular plug, self-expanding stent-graft was placed to cover the iliac entry tear...

AIM: The Nellix was introduced to Asia in 2014. Data in Asians have been sparse. Two balloon expandable stents, each surrounded by a polymer-filled endobag are deployed in parallel to obliterate and seal the aneurysm. This paradigm shift to treating abdominal aortic aneurysms confers advantages for certain adverse aneurysm morphology that is outside the IFU for standard EVAR devices. We examine outcomes of fifteen Asian patients with concomitant infrarenal aortic and iliac artery aneurysms treated with the Nellix at our institution...

BACKGROUND: The treatment of acute limb ischemia (ALI) has barely changed over the last years. However, the progressive implementation of anticoagulants, antiplatelet agents or statins within the population might have modified the profile and prognosis of patients suffering an ALI. The aim of this study was to evaluate the current results of the management of ALI secondary to a native artery occlusion. METHODS: Retrospective study of 220 consecutive patients (mean age 78 years; 49% male) was conducted between 2007 and 2015...

BACKGROUND: Liver resection for intrahepatic cholangiocarcinoma (ICC) with invasion of the inferior vena cava (IVC) and hepatic veins (HV) is a challenging procedure. CASE PRESENTATION: We report a case of a 63-year-old woman with a 6-cm, centrally located liver mass. Her biochemistry results were normal except for a Ca19-9 level of 1199 U/ml. The liver biopsy was consistent with ICC and 60% macrosteatosis. Abdominal CT scans revealed a large central mass invading the left HV, middle HV and right HV, infringing on their junction with the vena cava...

We constructed a UC-VEGF-SMC three dimensional (3D) scaffold to explore its effect on blood vessel regeneration and bladder repair function in a rabbit model with bladder injury. Rabbit adipose tissue-derived stem cells (ADSCs) were cultured to construct pluripotent stem cell systems that can be induced to differentiate into urothelial cells (UCs) and smooth muscle cells (SMCs). Reverse transcriptase-polymerase chain reaction (RT-PCR), enzyme-linked immunosorbent assay (ELISA), immunofluorescence, MTT assay and HE staining were used in our study...

BACKGROUND & AIMS: Portosystemic encephalopathy (PSE) is a major complication of trans-jugular intrahepatic porto-systemic shunt (TIPS) placement. Most devices are self-expandable polytetrafluoroethylene-covered stent grafts (PTFE-SGs) that are dilated to their nominal diameter (8 or 10 mm). We investigated whether PTFE-SGs dilated to a smaller caliber (under-dilated TIPS) reduce PSE yet maintain clinical and hemodynamic efficacy. We also studied whether under-dilated TIPS self-expand to nominal diameter over time...

PURPOSE: To describe the uses and advantages of hybrid vascular grafts (HVGs) for complex iliofemoral revascularization procedures. CASE REPORT: We report 3 cases of iliofemoral occlusions repaired with the Gore HVG, used as an alternative technique to standardized common femoral artery (CFA) endarterectomy associated with iliac stenting or open repair. The indication in each of the 3 cases was different: In the first case, there was an absent CFA secondary to a mycotic pseudoaneurysm, in the second case, an iatrogenic lesion of the posterior wall of the CFA during the intervention was performed, and in the third case, the indication was because of thrombosis of a previous iliofemoral revascularization procedure...

Background In-stent restenosis has been recognized as a distinct clinical entity that warrants a repeat procedure either in the form of percutaneous reintervention or coronary artery bypass grafting. Multivessel grafting with endarterectomy and explantation of the stent is rarely performed, with few cases reported in the literature. We aim to study the pathomorphology of the stent-vascular interface in coronary vessels undergoing in-stent restenosis. Methods Over a period of 3 years, 3 patients who had undergone angioplasty for diffuse coronary artery disease developed in-stent restenosis and were advised coronary artery bypass...
