Effectiveness of Intra-operative Contrast-Enhanced Ultrasound Assessment to Optimize Type II Endoleak Embolization.

Purpose: To analyze the effectiveness of type II endoleaks (T2E) embolization using intra-operative contrast-enhanced ultrasound (CEUS).

Methods: Consecutive patients treated for T2E underwent a standardized protocol with trans-arterial or trans-lumbar access, large volume embolization, onlay fusion, and intra-operative CEUS. Technical success was defined by exclusion of endoleak by CEUS.

Total Transfemoral Percutaneous Endovascular Aortic Arch Repair Using 3-Vessel Inner Branch Stent-Graft.

Endovascular repair has been introduced to decrease the morbidity and mortality associated with open surgical repair of aortic arch pathology. We illustrate total percutaneous transfemoral approach with a 3-vessel inner branch stent-graft to treat aortic arch aneurysm. ().

Outcomes of iliofemoral conduits during fenestrated-branched endovascular repair of complex abdominal and thoracoabdominal aortic aneurysms.

Objective: To describe the technical pitfalls and outcomes of iliofemoral conduits during fenestrated-branched endovascular repair (FB-EVAR) of complex abdominal aortic aneurysms (CAAAs) and thoracoabdominal aortic aneurysms (TAAAs).

Methods: We retrospectively reviewed the clinical data of 466 consecutive patients enrolled in a previous prospective nonrandomized study to investigate FB-EVAR for CAAAs/TAAAs (2013-2021). Iliofemoral conduits were performed through open surgical technique (temporary or permanent) in patients with patent internal iliac arteries or endovascular technique among those with occluded internal iliac arteries.

Single-Center Experience with the Femoral-to-Brachial Preloaded Delivery System for Fenestrated-Branched Endovascular Repair of Complex Aortic Aneurysms.

Purpose: To assess technical aspects and outcomes of fenestrated-branched endovascular aortic repair (FB-EVAR) using a femoral-to-brachial (FTB) preloaded delivery system (PDS) with two separate configurations.

Methods: Clinical data of all consecutive patients enrolled in a prospective study to evaluate FB-EVAR for complex abdominal and thoracoabdominal aortic aneurysms (CAAAs & TAAA) between 2013 and 2020 were reviewed. Patients treated with FTB-PDS were included.

Outcomes of low- and standard-profile fenestrated and branched stent grafts for treatment of complex abdominal and thoracoabdominal aortic aneurysms.

Objective: We compared the outcomes of fenestrated-branched (FB) endovascular abdominal aortic aneurysm repair (EVAR) using low-profile (LP) and standard-profile (SP) stent grafts for the treatment of complex abdominal aortic aneurysms (CAAAs) and thoracoabdominal aortic aneurysms (TAAAs).

Methods: We reviewed the clinical data of 466 consecutive patients (70% male; mean age, 74 ± 8 years) enrolled in a prospective nonrandomized study to investigate FB-EVAR for the treatment of CAAAs and TAAAs (2013-2021). The endpoints compared between the patients treated with LP (18F-20F) and SP (20F-22F) devices included procedural metrics, access-related complications, major adverse events (MAE), patient survival, freedom from secondary intervention, thromboembolic events, stent graft integrity issues, aneurysm sac enlargement, and the rate of sac shrinkage.

Impact of gap distance between fenestration and aortic wall on target artery instability following fenestrated-branched endovascular aortic repair.

Objective: Target artery (TA) instability has been the most frequent indication for secondary intervention after fenestrated and branched endovascular aortic repair (FB-EVAR) of pararenal and thoracoabdominal aortic aneurysms (TAAAs). The aim of the present study was to evaluate the effect of the gap distance between the endograft reinforced fenestration and TA origin at the aortic wall (fenestration gap [FG]) on target-related outcomes after FB-EVAR.

Methods: The clinical data and imaging studies of 430 patients enrolled in a prospective, nonrandomized study to evaluate FB-EVAR using manufactured stent grafts were reviewed.
