Objective The purpose of the study is to evaluate normal anatomical areas of infrarenal inferior vena cava, common iliac, external iliac and common femoral veins by intravascular ultrasound with the goal of assisting the development of venous-specific stents in the treatment of iliac vein stenosis. Method From February 2012 to December 2013, 656 office-based venograms were performed in our facility. Among them, 576 were stented and 80 were not. The measurements of veins were done intraoperatively using an intravascular ultrasound catheter to record areas of the inferior vena cava, proximal, middle and distal segments of common iliac vein, external iliac vein and common femoral vein...

BACKGROUND: Extended-field chemoradiation therapy is usually performed in patients with locally advanced cervical cancer (LACC) and paraaortic (PA) node metastases. Considering the very low rate of skip metastases above inferior mesenteric artery, ilio-inframesenteric paraaortic lymph node dissection (IM-PALND) seems to be an adequate pattern of PALND. Our objective was to assess the accuracy of this management to determine PA nodal status in comparison with infrarenal paraaortic lymphadenectomy (IR-PALND) in case of squamous or glandular cervical cancer...

Aortic cross-clamping induced ischemia reperfusion (IR) is an important factor in development of postoperative acute cardiac injury following abdominal aortic surgery. We investigated the possible antioxidant/anti-inflammatory effects of fluoxetine (FLX), which used widely as a preoperative anxiolytic, on cardiac injury induced by IR of infrarenal abdominal aorta. FLX was administered to IR (60-min ischemia and 120-min reperfusion) performed rats for 3 days, once daily at 20 mg/kg, i.p. dosage. Results were compared to control and non-FLX treated IR performed rats...

INTRODUCTION: The Nellix Endovascular Aneurysm Sealing (EVAS) System is an alternative endovascular treatment option for infrarenal aortic aneurysms (AAA) with a unique appearance on Computed Tomography Angiography (CTA). Normal evolution of post-EVAS CTA appearance follow-up is still largely unknown and important in order to timely detect eventual complications. OBJECTIVE: To assess the normal appearance of CTA images 30 days and 1 year after EVAS in 50 consecutive patients...

OBJECTIVE: To achieve an optimal sealing zone during endovascular aneurysm repair, the intended positioning of the proximal end of the endograft fabric should be as close as possible to the most caudal edge of the renal arteries. Some endografts exhibit a small offset between the radiopaque markers and the proximal fabric edge. Unintended partial renal artery coverage may thus occur. This study investigated the consequences of partial coverage on renal flow patterns and wall shear stress (WSS)...

BACKGROUND: Increased renal complications have been suggested with suprarenal stent grafts, but long-term analyses have been limited. Therefore, the purpose of this study was to evaluate the effect of endograft choice on perioperative and long-term outcomes. METHODS: We compared Medicare beneficiaries undergoing endovascular AAA repair from 2005-2008 with endografts with infrarenal fixation and a single docking limb (AneuRx, Excluder) to those with suprarenal fixation and two docking limbs (Zenith), or a unibody configuration (Powerlink)...

BACKGROUND: Temporary hepatic ischemia is inevitable during open aortic surgery when supraceliac clamping is necessary, as in thoracoabdominal or pararenal aneurysms. Remote ischemic preconditioning (RIPC) has been described as a potential protective means against ischemia - reperfusion injury (IRI) in various tissues including the liver. The aim of this experimental study was to detect the effect of RIPC on liver IRI in a model of supraceliac aortic cross-clamping. METHODS: An animal study was performed...

OBJECTIVE/BACKGROUND: Abdominal aortic aneurysm (AAA) maximum antero-posterior diameter (MAPD) is the parameter most commonly used to inform the timing of surgical intervention. However, other factors, such as growth rates and patient comorbidities are likely to be important considerations as they may influence AAA related complications including rupture, operative outcomes, and the clinical and cost effectiveness of continued surveillance. METHODS: This was a retrospective analysis of a 20 year period of a single centre AAA surveillance database...

BACKGROUND: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms exposes patients and healthcare professions to the deterministic and stochastic effects of ionization radiation. The study aim was to determine our standard of radiation exposure in infrarenal EVARs and compare it against other published data and national guidelines. METHOD: A retrospective analysis of a prospectively collected database of patients undergoing EVARs was obtained. Radiation dose, fluoroscopy time, aneurysm size and patient characteristics were collected...

BACKGROUND: Complications of endovascular aneurysm repair (EVAR) include endoleaks, proximal neck dilatation and stent migration, which have a greater likelihood with larger neck angulations. To mitigate against these complications endostapling of the stent-graft to the aortic wall is being implemented. With this extra stage in EVARs, this study aims to establish whether use of endostapling increases patient radiation exposure. METHOD: A retrospective analysis of a prospectively collected database of patients undergoing infrarenal EVAR and EVAR with endostapling was obtained...

BACKGROUND AND IMPORTANCE: The median sacral artery (MSA) is a relatively small vessel that always arises from the posterior, terminal part of the infrarenal aorta. In most cases, the MSA runs behind the iliocaval junction. Here, we describe a very rare case of an MSA running in front of this junction. CASE REPORT: During a human cadaveric dissection of the retroperitoneal area, we unexpectedly observed that the MSA passed in front of the left common iliac vein...

Etiologic diagnosis of an eosinophilic pleural effusion (EPE) presents a diagnostic challenge when intrapleural air and blood have been ruled out as its proximate causes. Among the causes of EPE, those that require immunosuppression for the underlying disease include connective tissue diseases, sarcoidosis, vasculitis, and eosinophilic pneumonia. We present a case of clinically suspected Behcet's syndrome based on a 10-year history of recurrent multiple oral ulcers and human leukocyte antigen-B51 positivity who presented with only an EPE...

Although widely used as a preclinical model for studying venous diseases, there is a scarcity of in vivo characterizations of the naïve murine venous system. Additionally, previous studies on naïve veins (ex vivo) have not included the influence of surrounding structures and biomechanical forces. Using MRI, we noninvasively quantified the cross-sectional area, cyclic strain, and circularity of the venous system in young and old, male and female C57BL/6 mice. We investigated the most common venous locations used to perform venous disease research: the common jugular vein, suprarenal inferior vena cava (IVC), infrarenal IVC, common iliac vein, and common femoral vein...

INTRODUCTION: Endovascular aneurysm repair (EVAR) is the most commonly used approach for treatment of abdominal aortic aneurysms (AAA). Testicular infarction is a rare complication of EVAR. A novel case of acute global testicular infarction post-EVAR from cholesterol embolisation mimicking torsion is presented. REPORT: A 75 year old man developed acute right testicular ischaemia requiring orchidectomy following EVAR of an infrarenal aortic aneurysm. The patient was initially diagnosed with testicular torsion as the aetiology of the infarction; however, on re-analysis of histopathology it was found to be secondary to cholesterol emboli...

Arterial conduits are a well-recognized technique used in liver transplantation to achieve allograft arterial inflow when conventional hepatic arterial inflow is compromised. Indications for ectopic inflow include native arterial disease at the time of initial transplantation, as well as reconstruction in the setting of thrombotic complications. Although supraceliac or infrarenal aortic reconstructions are preferred approaches, the right common iliac artery represents a viable alternative. We present the case of a morbidly obese patient with occlusive atheromatous plaque at the celiac origin not amenable to preoperative angioplasty who underwent reconstruction with a donor iliac artery conduit to the recipient right common iliac artery...

BACKGROUND: Several recent reports have demonstrated that the preoperative sensitivity and accuracy of identifying and locating non-palpable testes increases with the use of conventional MRI, in addition to diffusion-weighted imaging (DWI). Therefore, pre-operative prediction of the presence and location of testes using imaging techniques may guide management of intra-abdominal testis. Fowler-Stephens orchiopexy is effective for treating patients with intra-abdominal testis; however, long-term testicular function after this procedure has not been clarified...
