CAR 13. The “Sleeve-Shaping” Technique in the Treatment of Complex Peripheral Artery Aneurysms: Report of Two Cases

Peripheral artery aneurysms (PAAs) include popliteal, femoral, carotid, subclavian, upper limb, and visceral aneurysms, the incidence of which is much lower than that of abdominal aortic aneurysms. The treatment approach most recommended for PAAs is complete resection of the aneurysm sac followed by arterial reconstruction or endovascular repair with a stent graft. Here, we present a new technique, “sleeve shaping,” in the surgical treatment of two complex cases of extracranial carotid and subclavian artery aneurysms.

We evaluate the crimping strain, sealing stress and contact forces on a Nitinol stent deployed in the aorta during endovascular aortic (or aneurysm) repair (EVAR) procedures. Nitinol shape memory effect (SME) is used. We also study the fluid-structure interaction (FSI) of the blood flow on the stented aorta.

This study evaluates the relationship between aneurysm sac regression after EVAR and the presence of morphological features in the thoracic aorta that can be associated with a subclinical aortic dissection, termed dissection morphology in this study.

Hostile infrarenal proximal neck ( β) anatomy of abdominal aortic aneurysm has been associated with increased risk of aneurysm-related complications after endovascular aneurysm repair (EVAR). However, there is a paucity of literature addressing the suprarenal angle (α). The aim of this study was to evaluate short- and long-term out comes after EVAR in patients with severe suprarenal neck angulation (α>60 degrees).

Abstract OBJECTIVE: The aim was to compare peri-operative (30 day and/or in hospital) mortality between women and men in the Netherlands after elective repair of an asymptomatic abdominal aortic aneurysm (AAA). METHODS: This was a retrospective study using data from the Dutch Surgical Aneurysm Audit (DSAA), a mandatory nationwide registry of patients undergoing AAA repair in the Netherlands. Patients who underwent elective open surgical (OSR) or endovascular aneurysm repair (EVAR) of an asymptomatic abdominal aortic aneurysm (AAA) between 2013 and 2018 were included. Absolute risk differences (ARDs) with 95% ...

Authors: Shah M, Patel M, Sanghvi K Abstract An 81-year-old Caucasian male with a known abdominal aortic aneurysm (AAA) was referred to the endovascular clinic. One month after successful endovascular repair, surveillance CTA showed endoleak with presence of contrast within the aneurysmal sac. An elective repair was performed.

AbstractPurposeTo evaluate the incidence of acute renal failure and chronic kidney disease due to occlusion of accessory renal arteries during endovascular aneurysm repair of infrarenal abdominal aortic aneurysm.Material and MethodsWe retrospectively reviewed the course of 181 patients (mean age, 71, SD  ± 9  years) who underwent EVAR of infrarenal abdominal aortic aneurysm. The renal vessel anatomy was analyzed in all pre- and postoperative CT scans. Diameter and origin of accessory renal arteries were evaluated. Renal function was determined by pre- and postoperative serum creatinine and ...

Authors: Catanese V, Sangiorgi G, Sotgiu G, Saderi L, Settembrini A, Donelli C, Martelli E Abstract BACKGROUND: Limb graft occlusion (LGO) is the third reason for hospital readmission after endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm. We reviewed the clinical features, incidence, anatomical and devices related predictive factors for LGO after EVAR, and compared them with our experience. METHODS: EVAR between 2010-2017 were included. Patients with LGO (LGO group) were matched for age and type of endograft with the rest of the entire cohort without LGO (control group). Clinical, anatomical, ...

Authors: Bewley BR, Servais AB, Salehi P Abstract Introduction: Abdominal Aortic Aneurysm (AAA) is a potentially life-threatening condition caused by the ballooning of the patient's aortic wall. One treatment for this condition, Endovascular Aneurysm Repair (EVAR), has demonstrated a greater degree of safety in the short-term and has the potential to be more cost effective than its open surgical counterpart. Areas Covered: EVAR comes with the added risks of late-term failure, however, as the endografts are subject to displacement, loss of seal against the aortic wall, or failure to serve as a means of bypassing the...
