Progressive dilatation of the false lumen in the arch and descending aorta has been encountered in one-third of survivors as a late sequelae following repair of ascending aortic dissection. Conventional treatment for the same requiring cardiopulmonary bypass and deep hypothermic circulatory arrest is associated with high morbidity and mortality especially in the elderly cohort of patients. Herein we report a case of symptomatic progressive aneurysmal dilatation of residual arch and descending thoracic aortic dissection following repair of type A aortic dissection, successfully treated by total arch debranching and ascending aortic prosthesis to bicarotid and left subclavian bypass followed by staged retrograde aortic stent-graft deployment. This case report with relevant review of the literature highlights this clinical entity and the present evidence on its appropriate management strategies. Close surveillance is mandatory following surgical repair of type A aortic dissection and hybrid endovascular procedures seem to be the most dependable modality for salvage of patients detected to have progression of residual arch dissection.

Background: Intravascular ultrasound (IVUS) use in aortic endovascular interventions, including thoracic endovascular aneurysm repair (TEVAR) and endovascular aneurysm repair (EVAR), may have similar benefits to those seen in coronary and peripheral interventions, but limited utilization and outcome data exist.
Methods: Centers for Medicare and Medicaid Services claims data were used to identify patients undergoing TEVAR and EVAR from 2016 to 2023. Utilization trends were stratified by region, urbanicity, distressed communities index, community versus academic center, Medicare versus dual enrollment status, indication, urgency, and presence of dissection with malperfusion.

Bicuspid aortic valve (BAV), the most common congenital cardiac anomaly, predisposes individuals to aortic stenosis and regurgitation due to valve degeneration. Abnormal hemodynamics, arterial wall characteristics, and genetic factors contribute to ascending aorta dilatation, potentially leading to severe complications like aortic dissection. Presently, the most recent guidelines propose that individuals with BAV requiring valve replacement due to valve dysfunction should undergo simultaneous replacement of the ascending aorta when the diameter of aortic dilatation exceeds 4.

Background: We sought to identify predictors of acute renal failure (ARF) following acute type A aortic dissection (ATAAD) and its implications on postoperative outcomes.
Methods: ATAAD cases were identified from The Society of Thoracic Surgeons - Adult Cardiac Surgery Database (2017-2022). Cases with chronic dissection, prior aortic repair, primary endovascular repair, preoperative extracorporeal membrane oxygenation, preoperative renal failure, and operative room deaths were excluded.

Objectives: Patients that survive acute aortic dissection (AD) remain at high risk of morbidity/mortality from structural changes of the aorta. Aortic surveillance is challenging, especially within a tertiary referral center. Our aim was to identify follow-up imaging and appointment rates, and factors associated with incomplete surveillance in patients with acute AD.

: Contemporary treatments of acute aortic dissection, including medical, surgical, and endovascular options, are remarkably effective at the management of malperfusion and rupture. Unfortunately, long-term studies indicate that 30%-50% of patients need secondary procedures to treat progressive aneurysmal enlargement of the untreated aorta. The Stent-assisted balloon-induced intimal disruption and relamination in aortic dissection repair (STABILISE) technique was introduced to improve long-term outcomes.
