OBJECTIVE: Spiral laminar flow was suggested as potentially the predominant arterial blood flow pattern many years ago. Computational fluid dynamics and flow rig testing have suggested there are advantages to spiral laminar flow. The aim of this study was to identify whether spiral laminar is the predominant flow pattern in a cohort of volunteers. METHODS: This study included 42 volunteers (mean age 66.8 years). Eleven arterial sites were examined, comprising bilateral examination of the common carotid artery, internal carotid artery, external carotid artery, common femoral artery, superficial femoral artery, and the infra renal aorta...

OBJECTIVES: Endovascular aortic aneurysm repair (EVAR) is now established as first line treatment for infra-renal aortic aneurysms in the United States. Recent data from randomized trials suggest elective EVAR is cost effective compared to open AAA repair (oAAA). Cost analysis for urgent aneurysm repair has not been reported. We evaluated the cost of elective and urgent EVAR and compared it to oAAA at a tertiary academic medical center. METHODS: All infrarenal AAA repairs performed from 2004-2010 were retrospectively reviewed (n=172)...

OBJECTIVES: The renal safety of suprarenal (SR) fixation stentgrafts has not been demonstrated yet. The principal objective of this study was to analyze the effect of the type of fixation of stentgrafts on the renal function at one year, by calculating the estimated glomerular filtration rate (eGFR). The secondary objective was the evaluation of the morphological repercussion of the implants at the renal level by CT. METHODS: This was a monocentric retrospective study, including all the patients treated electively between 2008 and 2014 with a bifurcated aortic stentgraft...

An off-the-shelf, small diameter tissue engineered vascular graft (TEVG) would be transformative to surgeons in multiple subspecialties. Herein, the results of a small diameter (ID ≈ 1 mm) vascular graft constructed from resorbable, amino acid-based poly(ester urea) (PEU) are reported. Electrospun PEU grafts of two different wall thicknesses (type A: 250 μm; type B: 350 μm) are implanted as abdominal infra-renal aortic grafts in a severe combined immune deficient/beige mouse model and evaluated for vessel remodeling over one year...

An anomalous development of infra-renal inferior vena cava leads to circumcaval ureter or preureteral vena cava, a rare congenital anomaly with an autopsy incidence of 0.9 per 1000. We present a case of circumcaval ureter and review the literature with a special emphasis on the paradigm shift seen during the last decade, in diagnostic and management strategies.

Iliac branch devices (IBDs) are commonly used to treat iliac artery aneurysms and maintain patency of the internal iliac artery or its branches. This case report illustrates another possible application for an IBD. We present the case of a 77-year-old male who underwent repair of his infrarenal aneurysm with an IBD as a bifurcated aortic stent-graft in a small diameter aorta to maintain bilateral common iliac artery patency.

A 73-year-old man was transferred for treatment of abdominal aortic aneurysm. He had no history of abdominal surgeries. Grafting between the infra-renal abdominal aorta and the bilateral common iliac arteries was performed. Proximal and distal cross clamps were applied for grafting. He developed chylous ascites on the 5th post-operative day, 2 days after initiation of oral intake. Fortunately, he responded to treatment with total parenteral hyper-alimentation for 10 days, followed by a low-fat diet. There was no recurrence of ascites...

Type II endoleaks are the most common endovascular complications of endovascular abdominal aortic aneurysm repair (EVAR); however, there has been a divided opinion regarding their significance in EVAR. Some advocate a conservative approach unless there is clear evidence of sac expansion, while others maintain early intervention is best to prevent adverse late outcomes such as rupture. There is a lack of level-one evidence in this challenging group of patients, and due to a low event rate of complications, large numbers of patients would be required in well-designed trials to fully understand the natural history of type II endoleak...

BACKGROUND: The incidence of coagulopathy in patients presenting with rAAA is not clear. The lack of high-quality evidence has led to various speculations, reliance on anecdotal experience, and suggestions about their appropriate haemostatic resuscitation. The aim of this systematic review is to establish the baseline coagulation status of infra renal ruptured abdominal aortic aneurysms (rAAA) against defined standards and definitions. METHODS: An electronic search of literature in Medline, CINHAL, Scopus Embase, and Cochrane library was performed in accordance with the PRISMA guidelines...

OBJECTIVES: Giant cell arteritis (GCA) may affect mid-size and large-size arteries. Although temporal arteritis is a well-characterized clinical entity, GCA of the thoracic aorta remains ill defined. The aim of the study was to evaluate the clinical presentation, surgical and mid-term outcomes in patients operated for GCA of the thoracic aorta. METHODS: A retrospective review of patients operated for GCA of the thoracic aorta was conducted. The diagnosis of GCA was established by the pathology report...

Delivery of therapeutic agents to enhance arteriovenous fistula (AVF) maturation can be administered either via intraluminal or external routes. The simple murine AVF model was combined with intraluminal administration of drug solution to the venous endothelium at the same time as fistula creation. Technical aspects of this model are discussed. Under general anesthesia, an abdominal incision is made and the aorta and inferior vena cava (IVC) are exposed. The infra-renal aorta and IVC are dissected for clamping...

AIM: Although the underlined mechanisms are still unknown, metabolic/coagulation alterations related to childhood obesity can induce vascular impairments. The aim of this study was to investigate the relationship between metabolic/coagulation parameters and endothelial function/vascular morphology in overweight/obese children. METHODS: Thirty-five obese/overweight children (22 pre-pubertal, mean age: 9.52±3.35 years) were enrolled. Body mass index (BMI), homeostasis model assessment index (HOMAIR), metabolic and coagulation parameters, [adiponectin, fibrinogen, high molecular weight adiponectin (HMW), endothelin-1, and vonWillebrand factor antigen] ultrasound early markers of atherosclerosis [flow-mediated dilatation (FMD), common carotid intima-media thickness (C-IMT), and anteroposterior diameter of infra-renal abdominal aorta (APAO)] were assessed...

We report a case of endovascular recanalization of complete thrombotic occlusion of the inferior vena cava (IVC) and bilateral iliac veins using the architectural knowledge of the in situ permanent IVC filter in a 23-year-old male. The infrarenal permanent IVC filter was TRAPEASE permanent vena cava filter (Cordis) placed at an outstation hospital for pulmonary embolism. Being permanent variant of filter, percutaneous removal was not possible. The patient had severe venous claudication and an attempt to recanalize the blocked filter was considered, in view of the age no justifiable indication for a long-term filter...

Takayasu's arteritis is a large vessel vasculitis that can be a challenging diagnosis to make and has a varied clinical presentation. Management largely depends on affected vessel disease severity and individual patient considerations. The diagnosis must be considered in a young patient with large vessel aneurysms. We present a case of a 30 year-old woman of Pacific Islander descent who presented to the Tripler Army medical Center Vascular Surgery Department in Honolulu, Hawai'i seeking repair of her abdominal aortic and renal artery aneurysms prior to conception...

BACKGROUND: In patients undergoing transfemoral transcatheter aortic valve implantation, previous endovascular interventions bear a risk for the valve frame to get stucked to the aortic stents. CASE PRESENTATION: We report on a 75-year-old frail patient with severe aortic stenosis and a rapid increase of an infra-renal aneurysm. He had a history of multiple endovascular interventions on the aorta. Due to his frail preoperative status we decided to perform a transfemoral transcatheter aortic valve implantation in combination with a simultaneous surgical abdominal aneurysm repair...
