BACKGROUND: Patients with distal residual after proximal repair of aortic dissection (AD) have shown unsatisfactory long-term prognosis. However, possible mechanisms and risk factors for distal aortic segmental enlargement (DSAE) have been poorly understood. METHODS: We analyzed 962 AD patients repaired to the descending aorta between 1999 and 2014. Aortic morphological characteristics of 419 patients (including 75 DSAE and 344 non-DSAE patients) were investigated and compared...

The aim of this review was to investigate presentation, aetiology, management, and outcomes of bowel ischaemia following EVAR. We present a case report and searched electronic bibliographic databases to identify published reports of bowel ischaemia following elective infra-renal EVAR not involving hypogastric artery coverage or iliac branch devices. We conducted our review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement standards. In total, five cohort studies and three case reports were included...

BACKGROUND:  Modified multivisceral transplantation (MMVTx) refers to the use of a graft that includes all abdominal organs except the liver. The use of this type of transplant in children and adults expanded over the last years with good results. However, long-term survival in experimental models has not been reported. Our aim is to describe in detail some technical modifications of MMVTx to obtain long-term survival. MATERIALS AND METHODS:  Syngeneic (Lewis-Lewis) heterotopic MMVTx was performed in 16 male rats (180-250 g)...

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: Radiation exposure during fluoroscopically guided interventions such as endovascular aortic repair (EVAR) is a growing concern for operators. This study aimed to measure DNA damage/repair markers in operators perfoming EVAR. METHODS: Expression of the DNA damage/repair marker, γ-H2AX and DNA damage response marker, phosphorylated ataxia telangiectasia mutated (pATM), were quantified in circulating lymphocytes in operators during the peri-operative period of endovascular (infrarenal, branched, and fenestrated) and open aortic repair using flow cytometry...

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...
