Treatment of a giant coronary artery aneurysm in an adult with a history of Kawasaki disease by resection and bypass grafting: report of a case.
We report herein the case of a 22-year-old man with a history of Kawasaki disease who developed a giant calcified aneurysm of the left main coronary artery. The aneurysm was successfully resected and coronary bypass surgery was performed using the bilateral internal thoracic arteries. The resected aneurysm, the maximal diameter of which was 27 mm, showed heavy calcification of the inner layer and extended into the adjacent coronary arteries, producing a significant narrowing of the lumen of both the left main trunk (50%) and the anterior descending branch (50%). Extensive intimal calcification presumably prevented normal luminal development and produced a significant narrowing as the patient grew into adulthood. A cause for stenotic lesions developing in the coronary artery adjacent to a coronary aneurysm in adults with a history of Kawasaki disease is suggested here by the resected aneurysm seen in this patient. Thus, adult patients with giant coronary artery aneurysms and significant stenotic lesions of the coronary artery associated with Kawasaki disease may require aneurysmectomy in addition to bypass surgery.
