Objective: The aim of this study was to evaluate the midterm outcomes of secondary extension of frozen elephant trunk (FET) by means of thoracic endovascular aortic repair (TEVAR).
Methods: This single-center prospective study was conducted in a tertiary aortic center on consecutive patients having undergone TEVAR with an endograft covering most of the 10 cm FET module with 2 to 4 mm oversizing. All patients were monitored by computerized tomography angiography (CTA) at sixth month and yearly thereafter.
Results: From January 2015 to July 2022, among 159 patients who received FET, 30 patients (18.8%) underwent a TEVAR procedure (13 for a thoracoabdominal aneurysm, 11 for a chronic aortic dissection and 6 for an emergency procedure). All connections were successfully achieved with 2 postoperative deaths (6.6%) and 1 paraplegia (3.3%). At a median follow-up of 21 months (interquartile range [IQR], 4.2-34.7), 5 patients (25%) required a fenestrated-branched endovascular aortic repair (F-BEVAR) extension followed by 4 patients with 5 reinterventions, 3 for a Type 3 endoleak due to disconnection between FET and TEVAR endograft, and 2 unrelated to the FET for a secondary Type 1C endoleak. All reinterventions were successful, without mortality or morbidity.
Conclusions: In this series, FET connection with a TEVAR endograft was effective with low postoperative morbidity but with a risk of aortic reintervention related to disconnection between the FET and TEVAR endograft. These results suggest the need for annual CTA monitoring with no time limit in patients following connection of the FET with a TEVAR endograft.
Clinical Impact: In this series of 30 patients, midterm outcomes of secondary extension of frozen elephant trunk (FET) by thoracic endovascular repair (TEVAR) showed 3 disconnections (10%) with a Type 3 endoleak between FET and TEVAR. These findings suggest the need for annual CTA monitoring with no time limit. But so far, only a few studies provide some information after one year while the risk of disconnection increases over time and becomes a concern after 3 years. This is the new message brought by our study.

Objective: Post-repair surveillance of ruptured abdominal aortic aneurysm (rAAA) is critical for detecting potential complications. Substantial loss to follow-up has been reported in populations undergoing elective endovascular aortic repair (EVAR); however, there is limited data on follow-up rate among patients presenting with rupture. Thus, we investigated follow-up trends and factors influencing retention at a major academic referral center with a wide service area.

We document a case of a 75-year-old patient with a history of hypercholesterolemia and hypertension, who underwent endovascular aortic repair (EVAR) for an infrarenal abdominal aortic aneurysm (AAA) with common iliac artery ectasia. Despite an initially successful procedure, the patient experienced recurrent episodes of acute limb ischemia in his right leg. Subsequent imaging revealed thrombus formation distal to the stent graft, constituting a potential source of embolization, which warranted a reevaluation of the treatment strategy.

Introduction And Importance: Internal iliac artery aneurysms repair represents a life-threatening condition due to their anatomical position and the risk of rupture. Iliac branch devices are strongly recommended for anatomically suitable patients, but limited alternatives exist when their use is unsuitable. The use of custom-made fenestrated endografts is well documented in other aortic territories, however, their application for the treatment of internal iliac artery aneurysm remains limited.

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.

The mainstay of management for uncomplicated type B aortic dissection is currently optimal medical therapy, targeting blood pressure and heart rate, along with serial imaging. There is a paucity of data that informs whether early intervention with thoracic endografting in this group of patients will promote aortic remodeling and better long-term outcomes. Investigations to date, including the Investigation of Stent Grafts in Aortic Dissection (INSTEAD), INSTEAD-XL, and Acute Dissection: Stent Graft or Best Medical Therapy (ADSORB) studies, have compared thoracic endovascular aortic repair (TEVAR) with optimal medical therapy in patients with uncomplicated type B aortic dissection but have not shown a benefit for TEVAR conclusively.
