A Case of Swelling of Lower Extremity due to Iliac Vein Occlusion with IgG4-Related Idiopathic Retroperitoneal Fibrosis / 日本心臓血管外科学会雑誌

A 62-year-old man presented with a chief complaint of swelling of the left lower extremity. Idiopathic retroperitoneal fibrosis had been diagnosed 6 years previously. Enhanced computed tomography demonstrated occlusion of the left common iliac vein, but without deep vein thrombosis, and a thick dense fibrous layer around the abdominal aorta and in front of the sacrum. After we administered steroid and anticoagulant therapy, remission of the swelling of the left lower extremity was obtained. Presently steroids are being gradually tapered, and he has remained free of recurrence of the swelling of his left lower extremity.

Aortic Root Replacement for Bicuspid Aortic Valve and Annuloaortic Ectasia in a Patient with Ankylosing Spondylitis / 日本心臓血管外科学会雑誌

A 48-year-old man was admitted with shortness of breath. He had been given a diagnosis of ankylosing spondylitis by an orthopedic surgeon 20 years previously. A grade III/VI to-and-fro murmur was audible at the left sternal border. Echocardiography revealed moderate to severe aortic regurgitation with annular dilatation. He had also suffered complained rigidity of the neck muscles and back pain for 20 years. He underwent aortic root replacement and his postoperative course was uneventful. Aortic valve regurgitation with ankylosing spondylitis in Japan has been seldom reported, compared with European or American. We discuss surgical problems and the management of these lesions are discussed.

A Case of Cystic Adventitial Disease of the Popliteal Artery and Study of 116 Cases Reported in Japan / 日本心臓血管外科学会雑誌

We report a rare case of cystic adventitial disease of the popliteal artery causing intermittent claudication. About 2 months previously, a 21-year-old man had sudden intermittent claudication in the left leg. The left-sided ankle brachial pressure index (ABI) at rest was 0.66. Computed tomography revealed that the arterial occlusion was segmentally caused by cystic lesions. A cystic adventitial lesion of the popliteal artery, measuring 9 cm in diameter, was surgically removed and reconstruction was performed with a saphenous vein graft. Postoperatively the left ABI improved to 1.01, and his symptoms disappeared. The histopathological diagnosis was cystic adventitial disease and the cysts were in the adventitia. The postoperative course was uneventful and he has been without recurrence for 14 months.
