Endovascular treatment for aortic abnormality is an excellent alternative option for patients who are not good candidates for conventional open surgery. Although the technique of placing endovascular stent grafts has evolved since the first grafts, the basic principles remain the same. Use of endografts is limited by anatomic criteria, and advances in graft design have allowed for more widespread use for a broader patient range. The most important limitations to overcome are achieving high-quality aortic neck "healthy" landing zone, smaller-diameter delivery systems, and endografts that allow for more angled aortic necks.

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.

Purpose: The use of surgeon-modified fenestrated endograft to treat a bleeding complication in the common iliac artery.
Technique: An Endurant limb graft was modified on back table in theater after planning the fenestration using a semi-automated centerline. The Endurant stent was planned to land flush at the aortic bifurcation.

Introduction: The Flow Re-direction Endoluminal Device (FRED) is a novel flow diverter with a unique double stent design, with an inner stent composed of 48 nitinol wires, and an outer stent with 16 nitinol wires. It is designed for endovascular cerebral aneurysm treatment, although, limited data exist regarding in-stent stenosis (ISS) rates associated with FRED devices.
Methods: A registry encompassing two North American comprehensive stroke centers was the base of this study.
Hybrid Repair of Ascending Aortic Intramural Hematoma and Arch Ulcer in a 74-Year-Old Woman - A Case Report.

BACKGROUND Acute intramural hematoma (IMH) of the ascending thoracic aorta and aortic arch is a life-threatening condition, particularly in elderly patients with comorbidities, due to its risk of progression and rupture. Unlike aortic dissection, IMH lacks an intimal tear, influencing both clinical presentation and treatment strategy. This report describes a 74-year-old hypertensive woman with type A IMH and a penetrating atherosclerotic ulcer (PAU), managed with a hybrid surgical approach that combines external Dacron wrapping of the ascending aorta and endovascular stenting of the aortic arch with in-situ fenestration of the supra-aortic arteries.
