The duplication of the inferior vena cava (IVC) is a rare congenital anomaly, which also has some variations regarding the complex embryological development of the IVC. In the typical form, infrarenal IVC segments are duplicated and the left IVC joins the left renal vein, which crosses anterior to the aorta in the normal fashion to join the right IVC. In variant forms, the interruption of the intrahepatic segment of the IVC, azygos or hemiazygos continuation, or retroaortic course of the renal vein may be seen...

A 50-year-old male smoker presented with a perforated colon cancer and underwent an extended right colectomy. Feculent peritonitis was treated with empiric antibiotics. Postoperatively he developed severe back pain and rising leukocytosis. Serial computed tomography revealed a rapidly expanding infrarenal aortic aneurysm. He was urgently treated with extra-anatomic bypasses and aortic resection. No organisms grew from the resected aortic wall. He was discharged in stable condition, and the ileostomy was reversed 9 months later...

OBJECTIVE: Endovascular aneurysm repair (EVAR) has progressively expanded to treat more challenging anatomies. Although EVAR in patients with wide infrarenal necks has been reported with acceptable results, there is still controversy regarding the longer-term outcomes. Our aim is to determine the impact of infrarenal neck diameter on midterm outcome following EVAR with a single endograft with suprarenal fixation. METHODS: A retrospective case-control study was designed using data from a prospective multicenter database...

OBJECTIVE/BACKGROUND: Neointimal hyperplasia (NIH) remains one of the leading causes of graft failure after vascular anastomoses. Cytotoxic drugs, such as rapamycin and tacrolimus, have been shown to inhibit the development of NIH. In this study, the aim was to test the impact of a sustained releasing tacrolimus-chitosan-eluting suture on the development of NIH in a rat model. METHODS: After tacrolimus-chitosan coating of a 7/0 polyvinylidene difluoride (PVDF) Trofilen(®) suture, the tacrolimus concentration on the coated suture and in vitro release trials were performed spectrophotometrically...

AIMS: Inflammation drives atherosclerosis complications and is a promising therapeutic target for plaque stabilization. At present, it is unknown whether local stenting approaches can stabilize plaque inflammation in vivo. Here, we investigate whether everolimus-eluting stents (EES) can locally suppress plaque inflammatory protease activity in vivo using intravascular near-infrared fluorescence (NIRF) molecular imaging. METHODS AND RESULTS: Balloon-injured, hyperlipidaemic rabbits with atherosclerosis received non-overlapping EES and bare metal stents (BMS) placement into the infrarenal aorta (n = 7 EES, n = 7 BMS, 3...

PURPOSE: To investigate safety and efficacy of hybrid treatment for infected aortic and iliac aneurysms. MATERIALS AND METHODS: Between July 2007 and May 2011, hybrid treatment was performed in 6 male patients (mean age, 67.7 y; range, 57-76 y). Hybrid treatment consisted of extraanatomic bypass (EAB) and isolation of infected aneurysm with vascular plugs. Aneurysms were divided into primary and secondary infected aneurysms. Primary infected aneurysm refers to an aneurysm arising from bacterial infection of the native arterial wall; secondary infected aneurysm refers to infection involving an aneurysm that was previously treated with graft placement...

We describe a case of a 42-year-old male patient with advanced autoimmune deficiency syndrome (AIDS) (CD4 count of 16 cells/mm(3)) found to have a ruptured infected infrarenal aortic aneurysm. Emergent in situ repair was performed with a Hemashield Dacron graft (Boston Scientific, Natick, MA). Aortic tissue cultures grew group D Salmonella. Patient was placed initially on intravenous ciprofloxacin followed by lifelong oral levofloxacin and trimethoprim. Over 2 years following repair, he remains asymptomatic, with repair intact and no recurrent infection...

We reported a case of spontaneous retroperitoneal hematoma (SRH) simulating a ruptured infrarenal aortic aneurysm. A 72-year-old man with a history of infrarenal aortic aneurysm and end-stage renal disease on hemodialysis presented with malaise and nonspecific central abdominal pain and left loin discomfort. An emergency computed tomography scan showed a large retroperitoneal hematoma and clinical suspicion of ruptured infrarenal aortic aneurysm. However, the hematoma was discontinuous with the aneurysm sac and raised the clinical suspicion on dual pathology...

OBJECTIVE: Coverage of an accessory renal artery (ARA) during endovascular aneurysm repair (EVAR) may result in renal infarction (RI) or decline in renal function. Until now, it remains vague which patients are at risk to develop these complications. We therefore analyzed the effect of ARA sealing by EVAR with respect to the occurrence of RI and renal function. METHODS: A retrospective analysis of the medical records and computed tomographic scans of patients who underwent EVAR within a period of 5 years was performed...

Inferior vena cava (IVC) filter use is widespread in patients with venous thromboembolism (VTE) and temporary contraindication to anticoagulation, though timely removal is often not performed. We report the case of an expectoration of an IVC filter strut. Review of the patient's prior imaging confirmed an infrarenal Bard G2 filter with an absent strut, which was visualised in the left lung base. The strut was presumed to have embolised to a pulmonary artery branch and eroded into an adjacent bronchus. Subsequent fluoroscopically guided filter retrieval was successful...

BACKGROUND: Inferior vena cava repair after planned and unplanned venotomy is performed by either interposition bypass, patch venopasty, or lateral venorrhaphy and primary repair. Primary repair of the inferior vena cava avoids the use of foreign material and allows an all-autologous repair in an expeditious fashion. The purpose of this study was to demonstrate the utility of inferior vena cava repair, determine the degree of inferior vena cava stenosis, and examine clinical outcomes after primary repair...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) is the optimal therapy for complicated acute type B aortic dissection (aTBAD). This study examined clinical outcomes and aortic remodeling parameters after TEVAR for patients with complicated aTBAD. METHODS: From January 2012 to December 2015, 51 patients underwent TEVAR for complicated aTBAD. Preoperative and postoperative imaging studies were analyzed for sizes of the true lumen (TL) and false lumen (FL) and for the FL thrombosis status at five locations in the thoracic and abdominal aorta...

Hostile infrarenal aortic neck anatomy presents a challenge for the endovascular treatment of abdominal aortic aneurysm. Open surgical repair has been seen as the gold standard treatment for juxtarenal abdominal aortic aneurysm; however, endovascular techniques are now becoming more prevalent, particularly in patients deemed high risk for morbidity and mortality with open repair. The morphology of an aneurysm is a determinant of long-term outcomes, and short aneurysm necks are associated with poorer outcomes and a higher rate of secondary reinterventions...

As endovascular treatment of abdominal aortic aneurysms has become established, there has been growing focus on treatment of the aneurysmal iliac artery. Isolated, large iliac aneurysms >30 mm pose a risk of rupture, but, in addition, 20% to 30% of abdominal aortic aneurysms are associated with iliac aneurysmal dilatation, which can compromise long-term outcomes. Endovascular solutions are evolving and until recently have utilized standard stent graft technology. The endovascular aortic sealing system was introduced as a new, effective method for the treatment of infrarenal aortic aneurysms...

BACKGROUND: Bioengineered living autologous valves with remodeling and growth capacity represent a promising concept for future cardiac and venous valve repair. A meticulous understanding of the mechanisms involved in recellularization and remodeling is essential for the safe and efficient clinical translation of this technology. In this context, the first investigations of bioengineered vascular grafts in immune-incompetent or transgenic rodents represented an important step. However, the in-vivo assessment of bioengineered synthetic scaffold-based (biodegradable) valve replacements in rodent models has not been achieved to date...

OBJECTIVE: Percutaneous recanalization and stenting is currently the standard of care for symptomatic chronic total occlusions (CTOs) of the iliofemoral veins. CTO lesions involving the inferior vena cava (IVC) present a more complex patient subset. In this series we describe our single-center experience with endovascular recanalization of symptomatic occlusions of the IVC. METHODS: Patients were evaluated with duplex ultrasound imaging, venous function tests, and venography before intervention...
