Iliac venous aneurysms are rare vascular abnormalities that may be manifested by abdominal masses, pelvic tenderness, or hypovolemia and may lead to rupture, thrombosis, pulmonary embolism, paradoxical embolism, or death. Inferior vena cava agenesis, like venous aneurysm, is an uncommon condition that may present with deep venous thrombosis. This report describes a patient with inferior vena cava agenesis and iliac venous aneurysm rupture treated with emergent iliocaval reconstruction and endovascular stent graft placement...

Background: The present study tries to compare the unintended outcomes of the Catania stent versus Xience stent in patients undergoing angioplasty. Materials and Methods: In a three month, follow-up, double-blinded, randomized controlled trial, 83 patients undergoing angioplasty, who met the inclusion criteria were entered into the study. After randomization 43 patients were treated with the Xience stent and 40 patients with the Catania stent. Stent-related outcomes such as Cardiac and Non-Cardiovascular Death, Myocardial Infarction (MI), Target Lesion Revascularization (TLR), Stent Thrombosis (ST), Coronary Artery Bypass Grafting (CABG), Peripheral vasculopathy, and Cerebral Vascular Accident (CVA) were compared between the groups...

Drug-eluting stents (DES) are increasingly being used as a less invasive alternative to coronary artery bypass grafting. Early generation DES had durable polymers that provided acceptable efficacy outcomes but had high rates of stent thrombosis leading to myocardial infarction and death. Second-generation DES have improved outcomes by reducing stent thrombosis and recurrent stenosis. Newer DES with biodegradable polymers have similar efficacy as second-generation DES, but have higher rates of stent thrombosis...

Due to the aging population, the number of patients treated with aortic grafts or endografts continues to increase. Although infection after these procedures is uncommon, aortic graft infection is a life-threatening condition, and refinement of management guidelines based on implant pathophysiology is appropriate. In the early 1990s, our European collaborative retrieval program, European Group for Research on Prostheses Applied for Vascular Surgery (GEPROVAS) was commissioned to analyze the degenerative phenomenon occurring on explanted grafts or endografts...

OBJECTIVE: Because of advances in technology and experience of the operator, endovascular aneurysm repair (EVAR) has supplanted open repair to treat abdominal aortic aneurysm (AAA). The low 30-day mortality and morbidity of EVAR make the endovascular approach particularly suitable for patients at high surgical risk. However, endoleak or endograft migration requiring secondary intervention or open surgical conversion is a limitation of EVAR. The Nellix system (Endologix, Inc, Irvine, Calif) has been designed to seal the entire AAA to overcome these limitations with EVAR...

Despite the apparent superiority of arterial conduits for coronary artery bypass grafting (CABG), the long saphenous vein remains the most commonly used graft. The high failure rate of long saphenous vein grafts (SVGs) over time is therefore an important limiting factor for the long-term outcomes of CABG. Various methods to improve SVG patency have been proposed, although few have had a significant impact on clinical practice. External SVG supports have been a focus of research over the past 50 years, with their use intended to minimize well-documented pathophysiological changes that occur in the SVG following implantation into the coronary circulation...

INTRODUCTION: Suprahepatic caval resection and replacement of inferior vena cava (IVC) is standard procedure in deceased donor liver transplantation for patients with Budd-Chiari syndrome (BCS). However, replacement of IVC in living donor liver transplantation (LDLT) is difficult. We report a case of BCS successfully treated by LDLT without replacement of IVC. PRESENTATION OF CASE: A 52-years-old female with a primary BCS due to IVC thrombosis. A vena cava (VC) stent placed after angioplasty without improvement of the hepatic, portal venous flow and liver functions, Transjugular intrahepatic portosystemic shunt was considered and the patient had a rapid deterioration and increased ascites...

Infectious pseudoaneurysm (IPA) is a rare but devastating complication following renal transplantation that typically leads to graft loss and occasionally patient death. IPAs following kidney transplantation are most often mycotic in etiology, but have been sporadically reported to result from Pseudomonas aeruginosa infection. These IPAs occur at various anatomic sites, most commonly at the vascular anastomosis or iliac artery, and very rarely in the transplanted renal artery or hilum. Here we report the occurrence of single donor-derived P aeruginosa IPAs in two kidney transplant recipients with divergent allograft outcomes...

Primary aortoduodenal fistula (ADF) is a direct communication between the abdominal aorta and the gastrointestinal tract without any previous vascular intervention and represents a rare but critical cause of repeated and massive gastrointestinal bleeding. Primary ADF often occurs as a result of atherosclerotic aneurysm and infection, but ADF involving a normal-size aorta is rare; furthermore, ADF related to radiation therapy is extremely rare. We present the case of a 56-year-old man with a history of bowel obstruction due to radiation enteritis who was admitted with severe hematemesis and hemorrhagic shock...

A tailored therapy to patient requirements by combining endovascular and surgical steps can be necessary to prolong the life of a vascular access. Stent grafts play a growing role for the therapy of dialytic access complications. Randomized multi-center trials, however, support the on-label use of stent grafts in the treatment of graft venous outflow and in-stent restenosis. The main contraindication to their use is an ongoing infection. We report two cases of new off-label application of Viabahn (Gore, flagstaff, USA) stent graft...

BACKGROUND: Open surgical repair remains the "gold standard" treatment for chronic type B aortic dissection (cTBD) with aneurysm. Thoracic endovascular aortic repair (TEVAR) has gained popularity in recent years for the treatment of thoracic aortic diseases, including cTBD. We assessed the effectiveness of TEVAR in the treatment of cTBD using the Vascular Quality Initiative (VQI) database. METHODS: The VQI registry identified 4713 patients treated with TEVAR from July 2010 to November 2015, including 125 repairs for cTBD...

A 72-year-old man previously treated for an abdominal aortic aneurysm (AAA) was diagnosed with the 70-mm-sized type IIIb aortic dissection. Endovascular repair was considered, but there was no stent graft passing through the 8-mm iliac graft that was used for open repair of the AAA. We sealed the 5-mm-sized intimal tear site, using an Amplatzer Vascular Plug, which successfully repaired. The patient was discharged and had no complications. Serial follow-up computerized tomography scans showed that the vascular plug was positioned without migration, and the size of the aorta decreased...

OBJECTIVES: Ninety-five per cent of those operated on for popliteal artery aneurysm (PA) are men. Thus, PAs in women are difficult to investigate. The aim was to study the disease in women. METHODS: Women treated for PA in 1987-2012, prospectively registered in the Swedish vascular registry, Swedvasc, supplemented by case records, were compared with the larger male cohort. Survival was determined through cross linkage with the National Population Registry. RESULTS: 1509 patients (men and women), 1872 legs, were identified; of these 74 patients (4...

Celiac trunk aneurysms are uncommon vascular lesions; treatment is usually an open surgical operation; in the medical literature, only few cases of celiac aneurysm treated with endovascular technique are reported; coil positioning or stent-graft placement are described using a femoral vascular access as first choice.Here we describe the case of a 57-year-old man with an asymptomatic large celiac trunk aneurysm involving the origin of the splenic, left gastric and hepatic arteries. The patient was treated in an elective clinical setting with a totally endovascular procedure performed through the left radial artery...

Iliac artery occlusive disease can present as a sudden-onset acute thrombotic or thromboembolic event or as a chronic progressive atherosclerotic process that presents as claudication progressing to rest pain. Depending on the clinical presentation, the diagnosis is usually confirmed through Doppler vascular ultrasound, CT angiography, or MR angiography; the choice of imaging is usually based on modality availability and the presence of patient comorbidities such as chronic kidney disease. The Trans-Atlantic Inter-Society Consensus II classification system is commonly used to describe the extent of the peripheral vascular disease...

BACKGROUND: The endovascular management of arterial injuries has resulted in reduced operating time, blood loss, hospital mortality, lower incidence of sepsis, and decrease in mortality rates. For penetrating trauma, however, the benefits of endovascular therapy are questionable. PATIENTS AND METHODS: Data were obtained by retrospective analysis of electronic medical records. All patients with vascular trauma seeking care at our institution from January 2010 to December 2015 were reviewed...
