Successful One-Stage Resection of Intravenous Leiomyomatosis with Extension into the Main Pulmonary Artery / 日本心臓血管外科学会雑誌

We report a case of successful one-stage resection of intravenous leiomyomatosis (IVL) with extension into the main pulmonary artery. The patient was a 50-year-old woman, who was admitted to our hospital with clinical signs of syncope. Computed tomography (CT) and 3 D helical CT images showed a tumor arising in the left side of the uterus with extension into the pulmonary outflow tract. One-stage radical operation with cardiopulmonary bypass was performed. Because IVL is related to many fields concerning various organs, it is important that general surgeons, gynecologists and cardiovascular surgeons cooperate with each other.

A Case Report of One-Staged Coronary Artery Bypass Grafting and Revascularization of the Lower Extremities for Severe Ischemic Heart Disease and Leriche's Syndrome / 日本心臓血管外科学会雑誌

A 44-year-old man was given a diagnosis of severe ischemic heart disease and Leriche's syndrome. He had critical ischemia in the lower extremities and ischemic gangrene in a toe of the left foot. We planned a one-stage operation for these fatal diseases. To prevent irreversible ischemia of the lower limbs after mobilization of internal thoracic arteries or during extracorporeal circulation, we performed aorto-ilio femoral bypass grafting with extra-peritoneal approach first. Then conventional coronary artery bypass grafting was carried out for three coronary arteries with bilateral internal thoracic arteries (ITAs) and the saphenous vein. The postoperative course was uneventful.

A Surgical Case of Acute Pulmonary Thromboembolism with Multiple Mononeuritis / 日本心臓血管外科学会雑誌

The patient was a 63-year-old man with a history of multiple mononeuritis with hypergammaglobulinemia since 1980. The symptoms gradually worsened, and he had been bed-ridden since 1992. On February 28, 1997, he had sudden dyspnea after defecation. Echocardiography demonstrated a large thrombus in the right atrium and the right ventricle. Enhanced chest computed tomography revealed thrombi in the bilateral pulmonary arteries. The patient was considered to have acute pulmonary thromboembolism, and an emergency operation was indicated. Thrombectomy was performed under extracorporeal circulation through a median sternotomy. No thrombi were found in the right atrium or the right ventricle, and thrombi in the bilateral pulmonary arteries were removed completely. Four days after the operation, a Greenfield filter was implanted in the vena cava inferior because venography detected a thrombus in the right common iliac vein. The postoperative course was uneventful. No pulmonary rethromboembolisms were noticed after the operation. The long duration of being bed-ridden seemed to be the chief cause of thrombosis in the deep veins, and hyperviscosity due to hypergammaglobulinemia may have caused hyperthrombogenicity.

A Surgical Case of Acute Aortic Dissection with Antiphospholipid Syndrome / 日本心臓血管外科学会雑誌

The patient was a 52-year-old man with a history of antiphospholipid syndrome (APS), renal dysfunction and myasthenia gravis (MG). On May 2, 1998, he had sudden chest pain while sleeping. Enhanced computed tomography revealed acute aortic dissection (DeBakey type I). We performed emergency graft replacement of the ascending aorta and the aortic arch under extracorporeal circulation. Because of perioperative anuria, we used peritoneal dialysis (PD) just after the operation. Two days after the operation, we performed re-intubation nine hours after the extubation of the tracheal tube, and performed re-extubation three days later. For a while, his postoperative course was uneventful, but because of gradual worsening of APS, we administered more prednisolone, but 74 days after the operation, he died of multiple organ failure caused by an opportunistic infection, sepsis, and disseminated intravascular coagulation. This was very rare case of acute aortic dissection with MG and APS. After administration of more glucocorticoids, it is important to be wary of opportunistic infections.

Direct Aortic Reimplantation with Mitral Valve Repair for BWG Syndrome in an Adult Case / 日本心臓血管外科学会雑誌

Direct coronary artery reimplantation to the aorta and mitral valve repair were successfully performed in a 29-year-old female with Bland-White-Garland syndrome (BWG syndrome). Under cardiopulmonary bypass, the main pulmonary artery was completely transected and the left coronary artery was excised with a cuff of pulmonary artery wall. Then the left coronary artery was directly anastomosed to the ascending aorta. Mitral regurgitation was repaired with valvulo-annuloplasty. The post operative course was excellent.

Operative Cases of the Distal Aortic Arch Aneurysm through Median Sternotomy / 日本心臓血管外科学会雑誌

Seven patients underwent surgical repair of the distal aortic arch aneurysm from January 1990 to October 1997. They were 5 men and 2 women ranging from 63 to 78 years of age (mean, 72.7 years). All patients were operated with a median sternotomy only. There was one operative death, which was ruptured case. However, there were no major complications in non-ruptured cases. This retrospective study suggests that it is possible to repair the distal aortic arch aneurysm through a median sternotomy approach alone, when 1) descending aorta originates with normal size just distal to sacciform aneurysm, 2) the maximum diameter of the aneurysm is over 70mm and 3) distal involvement of the aneurysm does not extend beyond the bifurcation of the trachea. It is useful to retract descending aorta proximally by three threads with pledget for distal anastomosis in inclusion technique.
