Endografting, like open surgical repair of the thoracic aorta, can be complicated by paraplegia. We reviewed our thoracic endografting experience regarding the incidence and treatment of spinal cord neurologic events. Between February 2000 and July 2008, 346 patients underwent endoluminal grafting of the descending thoracic aorta. Indications for intervention included atherosclerotic aneurysms (45.9%), acute and chronic dissections (31.5%), miscellaneous lesions (13.6%), and penetrating aortic ulcers (8.9%). Ten women and 4 men (4.0%), with a mean age of 71.3 years, developed either paraparesis (1.7%) or paraplegia (2.3%). Nine (64.3%) of these patients had an aneurysm, 4 (28.6%) had acute or chronic type B aortic dissection, and 1 (7.1%) had a penetrating aortic ulcer; 3 (21.4%) of them had previously undergone open abdominal aortic aneurysm repair, and 13 (92.9%) required coverage of more than 20 cm of the aorta. Cerebrospinal fluid drainage was instituted in 7/8 paraplegic patients. Eight (57.1%) of the 14 patients recovered fully, 2 (14.3%) experienced partial recovery, and 4 (28.6%) had significant neurological deficits. Paraplegia following thoracic endografting appears to be associated with female sex, long-segment coverage of the thoracic aorta, and aneurysmal disease.

Objectives: This study assessed the association between chronic obstructive pulmonary disease (COPD) severity and postoperative mortality among patients undergoing thoracic endovascular aortic repair (TEVAR) and complex endovascular aortic repair (CEVAR).
Methods: A retrospective review of the Vascular Quality Initiative database identified elective TEVAR and CEVAR cases from 2013-2022 with endograft proximal landing zone ≥2 for thoracic or complex abdominal aortic disease. Symptomatic disease, ruptures, and urgent/emergent surgeries were excluded.

The optimal management of acute type A aortic dissection (ATAAD) remains a controversial subject. While some surgeons opt for a hemiarch approach to minimize bypass and cross-clamping time, others prefer partial or total arch replacement to prevent the need for additional operations. The advent of hybrid approaches offers a variety of options to the aortic surgeon in treating ATAAD.

Objective: Paravisceral aortic lesions present significant challenges for endovascular treatment. This retrospective analysis of consecutively treated patients from April 2017 to June 2021 aimed to analyse the outcome of primary intra-operative embolisation of aortic complicated pseudoaneurysms and gutter channels during parallel graft (PG) repair of paravisceral symptomatic aortic pseudoaneurysms.
Methods: Patients with symptomatic pseudoaneurysms of the paravisceral aorta treated with PGs using chimney or periscope configurations were included.

In the past 15 years, fenestrated-branched endovascular aortic repair (F-BEVAR) has progressively become the first-line option for management of most complex abdominal aortic aneurysms (AAAs); with increasing experience, as well as persistent technological refinements, F-BEVAR indications have been expanded to include rescue of failures after prior EVAR. Despite the feasibility and effectiveness, F-BEVAR procedures in the presence of prior infrarenal endografts may come with higher technical complexity that should be properly anticipated, and several anatomical challenges can be expected. Among these, presence of suprarenal bare stents from prior EVAR device are certainly a frequent scenario and may sometimes make target vessel cannulation more difficult because of encroachment on the target vessel origins.

Objective: Emergent complex abdominal aortic diseases are challenging to treat. During in situ laser fenestration (ISLF), aortic branches are covered and flow is restored with in situ fenestration of the stent graft, with promising midterm results. This study aimed to expand on the limited body of knowledge of midterm outcomes of ISLF in renovisceral aortic pathology in a multicentre setting.
