ABSTRACT

Takayasu Arteritis causes annuloaortic ectasia and coronary ostial stenosis, which may necessitate open heart surgery. However, pseudoaneurysms are sometimes observed postoperatively, making subsequent treatment difficult. We report thoracic endovascular aortic repair of a pseudoaneurysm of the ascending aorta with an anastomosis of the great saphenous vein in a 61-year-old female with a history of multiple open-heart procedures. Thirty years earlier, she underwent aortic valve replacement and coronary artery bypass surgery for aortic regurgitation, and right coronary ostial stenosis. Eleven years after surgery, an ascending aortic aneurysm was found and Bentall's surgery was performed. Multiple open thoracotomies were subsequently performed. Postoperatively, a pseudoaneurysm was found at the anastomosis between the ascending aorta and the great saphenous vein. The patient was transferred to the emergency room owing to hemoptysis and was diagnosed with a ruptured pseudoaneurysm at the anastomosis of the ascending aorta and the great saphenous vein. By inserting a stent graft into the ascending aorta, we avoided further complications and her prognosis was good. She was discharged on postoperative day 18 and did not experience any end leak for a year. Thoracic endovascular aortic repair in the ascending aorta is a minimally invasive procedure that may be useful for high-risk patients.

ABSTRACT

Recently, the incidence of pulmonary embolism (PE) after surgery began to increase in Japan and to prevent PE has become essentially important. During the period between July 2003 and August 2004, we placed 203 general surgical patients under our perioperative management using intermittent pneumatic compression (IPC) and compression stockings (CS). We evaluated the effect of our management on the prevention of postoperative PE in those patients. The incidence of PE, prognosis, complications, patient's complaints, cost-benefit were examined. No fatal PE occurred. One patient with low SpO2 had a chest pain and dyspnea but pulmonary scintigrams revealed no PE. Two other patients had contact dermatitis by CS and another patient using an epidural catheter suffered temporary paraplegia after heparin injection. The government has approved a fee for PE prophylaxis since April 2004. Our management using IPC and CS for PE prophylaxis after surgery proved to be an effective in reducing the risk of PE. However, we must take the atmost care in injecting heparin into patients with epidural catheters.

ABSTRACT

Morphology, location, timing of operation, and complications of multiple aortic aneurysms were investigated in 14 patients (10 men and 4 women with a mean age of 66 years). The locations of the aneurysms were as follows: aortic arch and thoracoabdominal aorta in 1, aortic arch and infrarenal abdominal aorta in 6, descending thoracic aorta and suprarenal abdominal aorta in 1, descending thoracic aorta and infrarenal abdominal aorta in 5, and thoracoabdominal aorta and infrarenal abdominal aorta in 1. Thoracic aortic aneurysms had a mean diameter of 63±13mm. The mean diameter of the abdominal aortic aneurysms was 54±13mm. In 1 patient, thoracoabdominal and infrarenal abdominal aortic aneurysms were operated on simultaneously. Eight patients, 5 with aneurysms of the aortic arch and infrarenal abdominal aorta, 2 with aneurysms of the descending aorta and infrarenal abdominal aorta, and 1 with aneurysms of the aortic arch and thoracoabdominal aorta, underwent two-staged operation. Aortic arch aneurysm was operated first in 3 patients, and abdominal aortic aneurysm in 5. Postoperative complications included spinal cord injury in 1 patient, bowel necrosis in 1, renal impairment in 2, respiratory impairment in 2, and hepatic impairment in 1. There was no perioperative death. Three late deaths occurred. Two staged operation is better for multiple aortic aneurysms. The first operation should be performed for the larger aneurysm.

ABSTRACT

We investigated the quality of life (QOL) after thoracic or thoraco-abdominal aneurysmectomy in patients who had undergone the procedure within the past 15 years. We compared preoperative to postoperative performance status (PS). Defining PS in the following manner: one increase in that PS grade indicated mild worsening while an increase is by 2 or more indicated severe worsening. Maintenance was indicated by no change of PS after surgery. The QOL maintenance rate was calculated based on the following formula.<br>QOL maintenance(%)=No. of no change case/No. of operated cases-No. of death×100<br>There were a total of 74 cases in whom follow-ups could be carried out after surgery. Among them, there were ascending and aortic arch aneurysms in 19 cases, descending aortic aneurysms in 20 cases, dissecting aneurysms in 27 cases and thoraco-abdominal aortic aneurysms in 8 cases. The QOL maintenance rate in the type B dissecting aneurysms was comparatively high (85.7%). There were cases of severe worsening of PS in the ascending and aortic arch aneurysms and type A dissecting aneurysms and the QOL maintenance rate was 50% in each other. We should obtain high operative results due to improve the QOL maintenance rate, and devise the operative procedure without functional disorders of the organs after surgery.

ABSTRACT

A chronic contained rupture of an infrarenal abdominal aortic aneurysm eroded a lumbar vertebra. A 53-year-old man complained of severe back pain for 6 months. Recently the back pain had increased. The patient looked well but a pulsatile mass in the abdomen was palpable. A CT and MRI of the abdomen and lumbar spine revealed the infrarenal abdominal aneurysm which demonstrated destruction of the third and fourth lumbar vertebra. At operation, there was a true aneurysm of the native aorta with a rupture of the posterior wall, resulting in a retroperitoneal hematoma. An orifice of the ruptured pseudoaneurysma was 2×2cm in size. An aortobiiliac graft was implanted. The patient did well postoperatively and was discharged on the 32nd postoperative day.

ABSTRACT

Preoperative and operative evaluation of the arterial reconstructive tract is very important to obtain a high reconstructed graft patency rate after femoro-popliteal bypass. We analyzed the graft patency rate of 40 cases in which the graft flow was measured immediately after completion of arterial reconstruction. The mean graft flow was 122.6ml/min in patients with above-knee (AK) reconstruction and 57.4ml/min in those with below-knee (BK) reconstruction. In cases with AK reconstruction, the three-year cumulative patency rates of grafts with a blood flow of 120ml/min or more (<i>n</i>=12) or less than 120ml/min (<i>n</i>=11) were 100% and 80.8%, respectively (<i>p</i><0.05). In cases with BK reconstruction, the three-year cumulative patency rates of grafts with a blood flow of 55ml/min or more (<i>n</i>=9) and less than 55ml/min (<i>n</i>=8) were 62.2% and 50.0%, respectively. All early occlusions (<i>n</i>=5) occurred in patients with BK reconstructions. Despite having a blood flow greater than 55ml/min, two cases became occluded in the early stage due to knee joint bending. It is considered that intraoperative measurement of the graft flow is one index to predict graft patency.
