ABSTRACT
A 51-year-old man underwent arch replacement for a thoracic aortic succular aneurysm in December 1996. The pathological examination indicated aortitis to be the cause of the aneurysm. At that time we did not surgically treat the abdominal aortic aneurysm (AAA) which was only 32mm in diameter. Sixteen months after the first operation, he complained of a pulsatile tumor in his left leg. Angiography revealed an aneurysm of the left superficial femoral artery. The artery distal to the aneurysm was occluded, and the left popliteal artery received collateral blood flow from the deep femoral artery. The size of the AAA increased to 48mm, an indication of repair. Aneurysmectomy of the left superficial femoral artery and replacement of the abdominal aorta were performed simultaneously. The operative findings showed that the aneurysm of the left superficial femoral artery had been ruptured and formed a pseudoaneurysm. The pathological findings demonstrated both aneurysm aortitis. After the second operation, he was given steroid therapy to control the inflammatory reaction and he has been well for one year.
ABSTRACT
A 49-year-old man who had no history of cardiac disease or intravenous drug abuse was referred to our hospital complaining of fever despite antibiotic chemotherapy. Blood culture was positive for <i>Streptococcus agalactiae</i>, and transesophageal echocardiography revealed vegetation attached to the tricuspid valve and moderate tricuspid regurgitation. Two-thirds of the anterior leaflet and a part of the posterior leaflet of the tricuspid valve were excised with the vegetation, and the remaining anterior leaflet was sutured to the posterior leaflet after annular plication. DeVega's annuloplasty was added to a diameter of two fingers. Following this procedure tricuspid regurgitation was minimal.
ABSTRACT
Metastasis to the heart is not so rare, but it is not diagnosed easily during patient's lifetime because clinical symptoms are not related to the nature of the tumor. We present a rare case of resection of cardiac metastasis of liposarcoma. A 37-year-old man suffered from dyspnea on effort was given a diagnosis of heart failure. He had already suffered from primary liposarcomas of the right heel which had been resected at age 28 and 32. Echocardiography revealed pericardial effusion and a tumor exiting from the apex. The mass grew rapidly and was excised using a cardiopulmonary bypass. The pathophysiological diagnosis was metastatic liposarcoma to the heart. The surgical margins of tumor were positive and cancer cells were exposed on the epicardial surfaces on some places. Adjuvant chemotherapy was therefore performed for 6 months. The patient was discharged after a good post-operative course and has been in good health for 40 months since the operation. Despite the generally poor prognosis of metastatic liposarcoma to the heart, combination of surgical treatment and chemotherapy yield a long period of survival in this case. It is important not only to establish the therapeutic strategy for metastatic tumor to the heart but also to detect it at an early stage.
ABSTRACT
A Case of abdominal aortic occlusion caused by acute aortic dissection (DeBakey's type III b) is reported. A 59-year-old woman was admitted with sudden onset back pain and sensory disturbance of bilateral lower extremities. The pulsations of bilateral femoral arteries were absent. CT and aortogram revealed dissection of the thoracic descending aorta and infrarenal aortic occlusion. Since ischemic change had progressed, bilateral axillofemoral bypass was performed for limb salvage, and the symptoms improved rapidly. Axillofemoral bypass is an easy and safe procedure even in the acute phase of aortic dissection. It provides fast reperfusion, and so is considered to be useful to preventing myonephrotic metabolic syndrome MNMS.
ABSTRACT
The Chiari network is an embryological remnant. It has rarely clinical importance but may very infrequently cause thrombosis and some other complications. Chest pain and pulmonary thrombosis were developed in a 23-year-old man. Cardiac ultrasonography revealed Chiari network in his right atrium, and no other thrombogenic lesions were found. Although anti-coagulant therapy was performed, pulmonary thrombosis were redeveloped. Chiari network was thought the cause of chest pain and pulmonary thrombosis. Operative removal of Chiari networks performed. The patient was postoperatively free from chest pain and pulmonary thrombosis.
