An iatrogenic fistula and consequent pseudoaneurysm developed between the right subclavian artery and right pulmonary artery as a result of misplacement of a hemodialysis access catheter. The patient, who was considered to be at high risk for surgical repair, successfully underwent endovascular treatment that involved insertion of two nitinol stents covered with expanded polytetrafluoroethylene (stent-grafts), one into the right subclavian artery and the other into a right upper lobe pulmonary artery. Multi-detector row computed tomographic angiography played an integral role in the evaluation of the patient's vascular injury and treatment planning.

Management of Anomalous Left Vertebral Artery During Open Total Arch Replacement.
Ann Thorac Surg Short Rep
December 2024
Division of Cardiac Surgery, Department of Surgery, Northwestern University Feinberg School Medicine, Chicago, Illinois.
Background: An anomalous left vertebral artery (aLVA) can complicate aortic arch surgery. We examined the safety of various aLVA revascularization strategies during open total arch replacement.
Methods: We retrospectively evaluated 92 patients undergoing total arch replacement from January 2018 to May 2023 and identified 11 patients with aLVA.
Understanding the Mechanisms of Main Bronchial Compression in Patients with Intracardiac Anomalies.
Ann Thorac Surg Short Rep
September 2024
Department of Pediatric Cardiovascular Surgery, Kanazawa Medical University, Ishikawaken, Japan.
Background: The study focuses on vascular compression of the main bronchus in the aortopulmonary space, examining potential contributors within the same axial plane. Its goal is to uncover mechanisms of bronchial compression in patients with intracardiac anomalies and review surgical outcomes, aiming to enhance future results.
Methods: The morphology and topology of structures within the axial plane of the aortopulmonary space were objectively analyzed, including the sternum, ascending aorta, heart, pulmonary artery, descending aorta, and other relevant elements.

The carotid and vertebral arteries are principal conduits for cerebral blood supply and are common sites for atherosclerotic plaque formation. To date, there has been extensive clinical and hemodynamic reporting on carotid arteries; however, studies focusing on the hemodynamic characteristics of the vertebral artery (VA) are notably scarce. This article presents a systematic analysis of the impact of VA diameter and the angle of divergence from the subclavian artery (SA) on hemodynamic properties, facilitated by the construction of an idealized VA geometric model.

Objectives: Mal-deployment of the thoracic endovascular aortic repair (TEVAR) stent graft during a frozen elephant trunk (FET) procedure for an acute type A aortic dissection (ATAAD) leads to devastating complications. We report a hemiarch replacement with TEVAR stent graft covering the aortic arch vessels salvaged through an endovascular approach.
Methods: A 69-year-old man with ATAAD in 2018, status post-hemiarch repair with TEVAR, presented in 2023 with progressive dizziness/syncope and lower extremity hypertension with inability to tolerate anti-hypertensives.

Managing an adult patient with aortic coarctation and associated anomalies presents a significant surgical challenge. We present a case of an adult male with aortic coarctation, pre-coarctation distal arch 7-cm aneurysm involving the origin of the left subclavian artery, and aberrant (lusoria) right subclavian artery. He was managed with one surgical approach, consisting of right carotid-subclavian bypass, exclusion of the right subclavian artery, proximal descending aortic replacement and reinsertion of left subclavian artery, using partial cardiopulmonary bypass.
