BACKGROUND: REBOA is utilized to decrease hemorrhage below the level of aortic occlusion (AO); however, the amount of collateral blood flow below the level of occlusion is unknown. The aim was to investigate blood flow patterns during complete AO in patients who underwent CT scan after REBOA. STUDY DESIGN: Patients between February 2013 and January 2017 who received REBOA and underwent CT scan with intravenous contrast during full AO were included. Patients were excluded if they had a CT scan performed with the balloon partially or fully deflated...

A 77-year-old man presented with acute-onset severe chest pain radiating to the back and elevated blood pressure. Multiphasic computed tomography of the aorta revealed an intimal tear in the descending thoracic aorta which extended both retrograde to the aortic root and antegrade to the infra-renal abdominal aorta. The initial impression, that the images showed a Stanford type B aortic dissection, was because the portion of the false lumen that extended beyond the aortic arch remained unopacified even on delayed phases, making it challenging to assess the extent of the dissection flap...

BACKGROUND: Immunoglobulin G4-related disease (IgG4-RD) is a newly recognized systemic condition characterized by high serum immunoglobulin G4 (IgG4) concentration and IgG4-bearing plasma cell infiltration in affected organs. Although it has become evident that IgG4-RD also involves the systemic aortic/arterial system, the precise details of this condition remain unclear. The present study sought to clarify the clinical features of IgG4-related periaortitis/periarteritis. METHODS: Among 223 patients with IgG4-RD, 179 (131 male, median onset age 67 years) were recruited for this study...

Abdominal aortic aneurysms (AAAs) are usually asymptomatic. The compressive effects of internal iliac aneurysms are well described in the literature; however, we report what we believe to be the first case of rupture of the renal pelvis caused by compression by an infrarenal AAA. We describe the subsequent management and briefly review the literature.

We report, to our knowledge, the first case of a rare syphilitic infrarenal aortouniiliac aneurysm with contained rupture that presented with midepigastric abdominal pain. Review of the patient's medical history revealed untreated syphilis and poorly treated congestive heart failure. Given his comorbidities, the patient was treated with an emergent endovascular aneurysm repair. His 30-day postoperative recovery period was uneventful, and follow-up imaging revealed complete resolution of the aneurysms. Syphilitic infrarenal aortic aneurysm is currently considered a rare entity in this era of antibiotics...

INTRODUCTION: Current methods of teaching endovascular aortic aneurysm repair (EVAR) planning involve non-criteria-based observations that lack validity. The primary aim of this study was to validate an EVAR Planning Objective Structured Assessment of Skill (EpOSAS) tool for the assessment of pre-operative EVAR planning skills. METHODS: Content analysis was performed in order to inform the formulation of EpOSAS domains. Thirty-five participants planned two cases of infra-renal abdominal aortic aneurysm for EVAR, using the OsiriX 7 platform...

Inferior vena cava (IVC) anomalies were rare and usually asymptomatic. Among these, anomalies absence of infra-renal IVC is the rarest anomaly. Absence of infra-renal IVC may present with symptoms of venous insufficiency and idiopathic deep vein thrombosis. Contrast enhanced CT and MRI abdomen play crucial role in diagnosing these anomalies. These patients can be managed conservatively or by venous bypass. Identification of these anomalies is important to avoid surgeries for varicose veins.

The coexistence of abdominal aortic aneurysm (AAA) and congenital pelvic kidney is infrequent. Various treatment modalities have been reported in literature for the treatment of the aforementioned 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 with this previously reported case, we would like to share our experience with additional prototype testing, before 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 endovascular repair (EVAR) planning, operative procedure, and subsequent follow-up is a threat for the onset of end-stage renal disease in patients with preoperative impaired kidney function. The purpose of this study was 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 EVAR (simple aortic-iliac anatomy: proximal and distal neck length ≥15 mm, no severe angulation), underwent EVAR through the following "near-zero contrast" approach, if their glomerular filtration rate (GFR) was <30 mL/min: preoperative planning was performed by noncontrast-enhanced computed tomography 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 <20 cc of isotonic iodinate contrast medium and contrast-enhancement DU (CEUS)...

We report a case of type 1 endoleak with an outflow via a lumbar artery (LA) following Nellix endovascular aneurysm sealing (EVAS) to discuss the specific peculiarities and management of this complication. A 64-year-old man (acetylsalicylic acid 3) underwent Nellix EVAS for an asymptomatic infrarenal aortic aneurysm. The 6-month duplex scanning ultrasound and magnetic resonance imaging showed a type IA endoleak with an outflow via an 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...

Ketura Preya A Wisner, Sarfraz Ahmad, Robert W Holloway
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...
