Addressing complications of large bore access in endovascular and cardiovascular procedures: An illustration of treatment options.

Abstract

BackgroundEndovascular procedures requiring large bore access, such as Transcatheter Aortic Valve Replacement (TAVR), Thoracic Endovascular Aortic Repair (TEVAR), and Endovascular Aneurysm Repair (EVAR), have become increasingly common. Despite advancements, complications from these procedures pose clinical challenges, especially in elderly and frail patients. The clinical objective of this paper is to demonstrate the complexities and innovative management strategies for complications that arise from large bore access.Case ReportThis report presents two cases illustrating percutaneous management of complications arising from large bore access during endovascular interventions. The first case involves a 74-year-old Asian female with a history of type A aortic dissection, who underwent TEVAR using a Gore TBE endograft. Post-procedure, the patient developed hemorrhagic shock due to disruption of the right external iliac artery. Interventions included upsizing the left femoral artery sheath, CODA balloon inflation in the distal aorta, and deployment of multiple VBX stents. The second case features a 24-year-old Caucasian female with a large pseudoaneurysm at the cannulation site in the aortic arch following a heart transplant. Successful TEVAR was performed to exclude the pseudoaneurysm. Closure of the right femoral artery access using 6 French ProGlide sutures was complicated, requiring balloon angioplasty to create an opening in the common femoral artery.ConclusionsThese cases highlight the challenges and innovative strategies in managing complications associated with large bore access during endovascular procedures. Insights gained from these experiences contribute to the armamentarium of interventionists, offering valuable guidance in addressing similar scenarios.
