The coexistence of Abdominal Aortic Aneurysm (AAA) and Congenital Pelvic Kidney (CPK) is infrequent. Various treatment modalities have been reported in literature for treatment of the above condition. We report a complete endovascular modality for the treatment of this association, especially for high-risk patients. Only one such treatment has been reported before. Compared to this previously reported case, we would like to share our experience with additional prototype testing, prior to surgery which provided us with more detailed information about the planning and deployment of the branched endograft...

BACKGROUND: The cumulative amount of iodinated-contrast-medium necessary for EVAR planning, operative procedure and subsequent follow-up is a threat for the onset of end stage renal disease in patients with pre-operative impaired kidney function. Purpose of this study is to describe a mini-invasive approach aimed to minimize the exposure of these patients to iodinated-contrast-medium and the subsequent risk of renal function worsening. METHODS: From 2012 to 2015, all patients with abdominal aortic aneurysm (AAA) at high-surgical risk and fit for standard endovascular repair (simple aortic-iliac anatomy: proximal and distal neck length ≥15mm, no severe angulation), underwent EVAR through the following "near-zero contrast" approach, if their glomerular filtration rate (GFR) was <30 mL/min: pre-operative planning was performed by non-contrast enhanced computed tomography (CT) and duplex-ultrasound (DU); the origin of renal/hypogastric arteries and aortic bifurcation was evaluated and matched with vertebral bone landmarks and the endograft deployed accordingly, using < 20cc of isotonic iodinate-contrast-medium and contrast-enhancement-DU (CEUS)...

We report one case of type 1 endoleak (EL) with an outflow via a lumbar artery following Nellix endovascular aneurysm sealing (EVAS) in order to discuss the specific peculiarities and management of this complication. A 64-year-old man ( ASA 3) underwent Nellix EVAS for an asymptomatic infra-renal aortic aneurysm. The 6-month Duplex scanning ultrasound and magnetic resonance imaging showed a type IA endoleak with an outflow via a lumbar artery (LA) combined with a stable aneurysmal sac size. The subsequent 9-month imaging controls showed no changes of the endoleak cavity but there was a slight enlargement in proximal neck size associated with the distal migration of both Nellix grafts...

Robotic-assisted laparoscopic surgery is the most common approach for the treatment of early-stage endometrial and cervical cancers in the US. Surgical staging requires pelvic and often aortic lymphadenectomy, depending on the primary tumor characteristics. Pelvic and aortic lymphadenectomy procedures may also be indicated for debulking of larger metastases to improve disease control. The infra-renal basin is an important anatomic site of metastasis from pelvic tumors, and robotic dissection techniques for this site have been described...

Covered Endovascular Reconstruction of Aortic Bifurcation (CERAB) is a new technique to treat extensive aortoiliac occlusive disease with covered expandable stent grafts to rebuild the aortoiliac bifurcation. Post stenting Doppler ultrasound (DUS) measurement of maximum peak systolic velocity (PSVmax) in the stented segment is widely used to determine patency and for follow up surveillance due to the portability, affordability and ease of use. Anecdotally, changes in hemodynamics created by CERAB can lead to falsely high PSVmax requiring CT angiography (CTA) for further assessment...

Our objective was to determine the relative merits of intervention or observation of type II endoleaks (T2Ls). A retrospective analysis was performed on 386 infra-renal endovascular aneurysm repair (IR-EVAR) patients from 2006 to 2015. Annual surveillance imaging of patients undergoing EVAR at our centre were analysed, and all endoleaks were subjected to a multidisciplinary team meeting for consideration and treatment. In the 10-year time frame, 386 patients (79.5±8.7 years) underwent an IR-EVAR. Eighty-one patients (21...

BACKGROUND: Deployment of a stent graft for the treatment of aortic dissections is normally performed in the true lumen. However, in some rare occasions landing in the false lumen may be appropriate. METHODS: We present 2 different cases of chronic aortic dissection, where we opted to land the stent graft into the false lumen to treat the associated aneurysm. RESULTS: For the first case, the goal of thoracic endovascular aortic repair (TEVAR) was to exclude the aneurysm from within the false lumen because of a slit-like true lumen...

We report the case for a 44-year-old patient without medical history, admitted in our department for bilateral acute limb ischemia (H6). The patient was hemodynamically stable and the physical examination shows limb sever ischemia (no femoral arterial pulses, coldness, cyanosis and paralysis). Abdominal CT angiography showed a complete occlusion of the infra renal abdominal aorta compatible with embolus. An embolectomy with Fogarty catheters was performed. Echocardiography showed a mass in the left atrium. Pathological examination of the material embolic confirmed the diagnosis of the cardiac myxoma...

Open repair for infra-renal abdominal aortic and iliac artery aneurysms (AAAs) is a robust treatment. On the other hand, endovascular aneurysm repair (EVAR) has been widespread because of its less invasiveness. However, patients after EVAR frequently require postoperative radiographic examinations and may feel anxiety for their endoleaks. We prospectively evaluated Health-related Quality of Life of the patients with these two fashions using the 8-item Short Form (SF-8). From 2011 to 2013, 89 consecutive elective cases of AAAs were treated...

Pericardial patches are commonly used in vascular surgery to close vessels. To facilitate studies of the neointimal hyperplasia that forms on the patch, we developed a rat model of patch angioplasty that can be used in either a vein or an artery, creating a patch venoplasty or a patch arterioplasty, respectively. Technical aspects of this model are discussed. The infra-renal IVC or aorta are dissected and then clamped proximally and distally. A 3 mm venotomy or arteriotomy is performed in the infrarenal inferior vena cava or aorta of 6 to 8 week-old Wistar rats...

BACKGROUND The etiology of deep venous thrombosis (DVT) may pose a significant diagnostic challenge because truly reversible causes of DVT are rare. In this regard, known pelvic anatomic abnormalities such as aortic and iliac aneurysms should be seriously considered as a complicating factor in patients presenting with acute DVT so as not to miss a potentially curable etiology of May-Thurner syndrome (MTS). CASE REPORT We report the case of a 69-year-old man with a known abdominal aortic aneurysm and bilateral iliac artery aneurysms who presented with an acute DVT...

OBJECTIVE: To evaluate the feasibility and results of using serosal patch of small bowel for repair and replacement of inferior vena cava (IVC) after resection of a part of infra-renal IVC in an animal model, as it may be encountered in extensive tumors of retroperitoneal and trauma patients. METHODS: Five healthy sheep of both sexes were prepared. After general anesthesia and laparotomy, a defect with 1 cm width and 4cm length was made on anterior aspect of infra-renal IVC, and then an adjacent loop of small bowel was brought and sutured continuously to cover the defect of IVC as a patch graft...

Chronic mesenteric ischemia (CMI) is a rare disorder caused by severe stenosis of the mesenteric arterial supply that results in postprandial pain and weight loss. Treatment options are surgical or endovascular. Surgical bypass can be performed in an antegrade fashion from the supraceliac abdominal aorta (AA) or the distal descending thoracic aorta or in a retrograde fashion from the infrarenal aorta or the common iliac artery. However, in some patients with disease of the descending thoracic aorta or the AA, another site for the proximal anastomosis needs to be found...
