INTRODUCTION: Bilateral common iliac artery (CIA) aneurysm (CIAA) is a rare entity. In the past decade, different endovascular approaches have been adopted for patients with several comorbidities or unfit for open repair (OR). Recently, the use of iliac branch stent graft has been proposed, resulting in satisfactory patency rates and decrease in morbidity. Currently, according to instruction for use, the iliac branch stent graft is to be used with aortobi-iliac stent graft conjunction...

PURPOSE: To report the outcomes of fenestrated endovascular aneurysm repair (FEVAR) and compare early and midterm results in relation to stent-graft complexity. METHODS: Between August 2006 and December 2014, 141 consecutive patients (mean age 72±7.6 years, range 50-89; 120 men) were treated electively with FEVAR for short-neck, juxtarenal, or suprarenal aortic aneurysms. Forty-five patients treated with stent-grafts featuring renal-only fenestrations were assigned to group A, while 96 patients receiving additional fenestrations for the superior mesenteric and/or celiac arteries were assigned to group B...

PURPOSE: To describe a technique suitable for treating severely angulated (>75°) necks during endovascular aneurysm repair using the Endurant stent-graft. TECHNIQUE: In the push-up technique, the suprarenal stent is released early to fix the proximal stent-graft in place so that each stent in the neck can be deployed individually without displacing the device upward. It is important to push the delivery system up after each stent deployment to allow the fabric between the stents to fold up circumferentially...

BACKGROUND: The surgical treatment of Crawford extent II aneurysms after thoracic endovascular aortic repair (TEVAR) remains challenging, because of the need to remove the failed endograft and the complexity of the aortic reconstruction. We retrospectively reviewed our experience with surgical management of Crawford extent II aneurysms after TEVAR using thoracoabdominal aortic replacement (TAAR). METHODS: Eleven patients (10 males, 1 female) with Crawford extent II aneurysm after TEVAR were treated with TAAR between August 2012 and May 2015...

INTRODUCTION: Understanding the relationship between patient risk factors, postoperative complications, and morbidity and mortality is important when considering elective endovascular aortic aneurysm repair (E-EVAR) performed to prevent aneurysm rupture mortality. We aimed to stratify complications in E-EVAR and explore their relationship with postoperative death. METHODS: E-EVAR cases from 2012 NSQIP were identified. 30-day complications were categorized as major (MAJCX) or minor (MINCX) using the Clavien-Dindo classification...

OBJECTIVE: Endovascular aortic aneurysm repair has become the principle technique used to treat abdominal aortic aneurysms. However, its long-term success is limited by complications, including type II endoleaks from lumbar arteries and the inferior mesenteric artery. Treatment of these endoleaks can be difficult. The most commonly performed procedure is embolisation via mesenteric or iliolumbar vessels. Embolic agents currently used include coils, glue and Onyx, all of which have their limitations...

OBJECTIVE: Short neck length, and angulated infrarenal aortic necks, are historically associated with sac expansion following endovascular abdominal aortic aneurysm repair. Aorfix (Lombard Medical, Inc, Irvine, Calif), a conformable stent graft US Food and Drug Administration approved for highly angulated necks, was investigated in the US Pythagoras Trial. We investigated the incidence of, and factors related to, sac regression and expansion following implantation of the Aorfix device...

OBJECTIVE: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs) has gained widespread use through a solid reputation of safety and effectiveness. However, some issues, such as endoleaks and sac growth over time, still arise as important concerns. Antiplatelet therapy, mandatory as secondary prevention of cardiovascular disease, may play a role in both phenomena by interfering with blood clotting properties and the inflammatory process associated with AAA. We analyzed whether different antiplatelet therapies were independent risk factors for type II endoleak (T2E) persistence and midterm sac growth after EVAR...

Spontaneous subarachnoid hemorrhage (SAH) affects people with a mean age of 55 years. Although there are about 9/100 000 cases per year worldwide, the young age and high morbidity and mortality lead to loss of many years of productive life. Intracranial aneurysms account for 85% of cases. Despite this, the majority of survivors of aneurysmal SAH have cognitive deficits, mood disorders, fatigue, inability to return to work, and executive dysfunction and are often unable to return to their premorbid level of functioning...

A 77-year-old man with a descending thoracic aneurysm associated with pseudocoarctation of the aorta underwent thoracic endovascular aortic repair (TEVAR). Computed tomography demonstrated kinking of the descending thoracic aorta. The aneurysm was located distal to a kinking and constricting aortic isthmus. TEVAR was performed because of the patient's comorbidity such as valvular heart diseases and postradiation status for the thoracic Hodgkin disease. TEVAR was successful but small aortic dissection was occurred distal to the stentgraft...

PURPOSE: To describe the planning and technique for implantation of the t-Branch off-the-shelf multibranched aortic endograft. TECHNIQUE: Total endovascular repair of thoracoabdominal aneurysms (TAAAs) with branched endografts is one of the most important paradigm shifts in the past decade. The t-Branch endograft, an off-the-shelf multibranched graft introduced in the European market in late 2012, allows treatment of patients with suitable anatomy in both the elective and urgent settings to avoid delays related to manufacturing time of custom-made devices...

Although small (<5cm) Abdominal Aortic Aneurysm (AAA) have been associated with symptoms and indication for intervention scarcely, the clinicians should never exclude such potential association especially in the absence of other overt pathological findings. In such cases, a surgical exploration with consequent intervention, if feasible, should be justified in order to prevent a detrimental evolution in a dubious scenario. In this article we present two cases of patients with small AAA presenting with severe abdominal pain...

Inferior vena cava (IVC) thrombosis is a rare complication of abdominal aortic aneurysm (AAA). A 70-year-old male patient of Italian origin presented with a 9.3 x 8.4 cm infrarenal AAA, which was treated by endovascular aortic repair (EVAR). He reported a history of ulcerative colitis and was on prednisolone 80 mg daily. Seven weeks postoperatively the patient was readmitted with a deep vein thrombosis including both iliac veins and IVC, and bilateral pulmonary embolism. Venous thrombectomy and decompression of the IVC was performed by partial resection of the aneurysm sac...
