OBJECTIVE: We compared the management of patients with symptomatic, unruptured abdominal aortic aneurysms (AAAs) treated at a tertiary care center between two decades. This 20-year period encapsulated a shift in surgical approach to aortic aneurysms from primarily open to primarily endovascular, and we sought to determine the effect of this shift in the evaluation, treatment, and clinical outcomes of patients with symptomatic AAA. METHODS: We reviewed 1429 consecutive patients with unruptured AAAs treated at a tertiary care hospital by six staff surgeons between 1995 and 2004 (era 1) and between 2005 and 2014 (era 2)...

We report a 78-year-old man who presents progression of his aneurysmatic pathology with previous abdominal infrarenal aortic surgery 20 years later. The computed tomography (CT) scan showed proximal degeneration of the infrarenal aorta, left iliac aneurysm and a new descending thoracic aneurysm close to the aortic arch. The surgical treatment was staged in two times due to the evolution of the aneurysm measures. First, the thoracic and the infrarenal aneurysms were covered each one with endoprosthesis. Four years later the iliac disease was solved with a branched specific iliac endograft...

Unlike autosomal dominant polycystic kidney disease (ADPKD), autosomal recessive polycystic kidney disease (ARPKD) is not generally known to be associated with vascular abnormalities. Only 4 cases of ARPKD patients with intracranial aneurysms have been reported previously. We present 2 ARPKD patients with extracranial vascular abnormalities: a young man with infrarenal aortic and iliac artery aneurysms complicated by dissection and a teenage girl with multiple splenic and gastric artery aneurysms and arterial vascular malformations...

OBJECTIVE: This study aimed to determine the natural history of spontaneous isolated abdominal aortic dissection (SIAAD) and to establish an optimal management strategy for patients with SIAAD. METHODS: We searched the database of thoracoabdominal computed tomography (CT) performed at a single institution from January 2003 to July 2016 using the keywords "aortic dissection" and "dissection AND aorta." Once a diagnosis of SIAAD was made, we investigated the initial clinical and morphologic features and aorta-related events for all patients and morphologic changes of the aortic dissection (AD) during the follow-up period for the patients who underwent follow-up CT scans...

OBJECTIVE: Hostile proximal aortic neck (HN) challenges the suitability for standard endovascular aneurysm repair (EVAR) of patients at high risk for "open" repair. However, there has been little if any focus placed on the individual role of the "nonlength" HN features in EVAR outcomes. The aim of this study was to evaluate their individual and potentially predictive role in outcomes of EVAR under HN conditions. METHODS: Data of 156 consecutive EVAR patients with short (<15 mm) HN, treated with the Endurant device (Medtronic Cardiovascular, Santa Rosa, Calif) at three European academic vascular centers between 2007 and 2015, were collected and retrospectively analyzed...

Herein, we report our experience of performing allogeneic orthotopic liver transplantation (LT) in nonhuman primates. We designed an allogeneic ABO-compatible orthotopic LT model in monkeys in a manner similar to that used in humans. We applied almost the same surgical procedures used for human conventional deceased donor LT. A total of 6 monkeys underwent allogeneic LT. One cynomolgus monkey aged 45 months (3.4 kg) and 5 rhesus macaque monkeys aged 50.2 ± 14.8 months (5.40 ± 0.33 kg) were used as recipients...

Presented herein is a clinical case report concerning the use of a hybrid technique in stagewise surgical management of a patient with distal dissection and an aneurysm of the thoracoabdominal portion of the aorta. The patient at high risk with the connective tissue dysplasia syndrome had a past medical history of prosthetic repair of the descending thoracic aorta with type-1 haemodynamic correction. Three years later, the findings of computed tomography demonstrated fenestration in the area of the distal anastomosis, a patent false channel, and an increase in the diameter of the unoperated thoracoabdominal portion of the aorta...
