  • Title: [Surgery in Elderly Patient for Coronary Arteriovenous Fistula and Giant Coronary Artery Aneurysm Associated with Cardiac Failure;Report of a Case].
    Author: Suzuki K, Yamashita O, Tsuboi H.
    Journal: Kyobu Geka; 2019 Feb; 72(2):140-143. PubMed ID: 30772881.
    Abstract:
    An 82-year-old woman visited the hospital with the chief complaint of dyspnea on light exertion. Computed tomography (CT) showed a coronary artery aneurysm and coronary arteriovenous fistulas. The pulmouary flow/systemic flow (Qp/Qs) ratio was 1.4, and the left-to-right shunt rate was 31%.Two anomalous vessels were identified. One arose from the right coronary artery, formed an aneurysm, and drained into the coronary sinus, while the other originated from the distal circumflex branch and drained directly into the coronary sinus. The aneurysm measured 50×45 mm. The anomalous vessel from the right coronary artery was ligated at the sites of flow from the right coronary artery and at the site of drainage into the coronary sinus. The circumflex artery was ligated at the last branch and at the site of drainage into the coronary sinus. The aneurysm was incised and the vessel flowing into the aneurysm was sutured closed. Postoperative CT showed no anomalous blood vessel and the circumflex artery was visualized up to the last branch.
