Successful one-stage surgical removal of intravenous leiomyomatosis with cardiac extension in an elderly patient.

Intravenous leiomyomatosis is a benign smooth muscle tumor that sometimes spreads to the right heart via the inferior vena cava. A complete surgical resection is necessary to ensure its successful treatment. Surgical removal has been performed safely in middle-aged patients. Here we report a case of successful surgical removal in an elderly woman (age 81 years). The woman was admitted with palpitation and diagnosed as having an intravenous leiomyomatosis with cardiac extension. She underwent a one-stage surgical removal with cardiopulmonary bypass and circulatory arrest. We therefore recommend a one-stage operation, if possible, even in elderly patients.

[Endovascular repair for ruptured thoracic aortic aneurysm and traumatic aortic injury].

In contrast to high mortality of open surgery for thoracic aortic catastrophes including ruptured thoracic aortic aneurysm (RTAA) and traumatic aortic injury (TAI), excellent short-term outcomes of thoracic endovascular aortic repair (TEVAR) have recently been reported. We report our single-center experiences with TEVAR for aortic catastrophes. Thirteen patients with thoracic aortic catastrophes (RTAA in 7 patients, TAI in 6 patients) have received TEVAR from February 2004 to June 2010. In cases of RTAA, 5 descending aortic aneurysm ruptures and 2 aortic arch aneurysm ruptures were included. In patients with arch aneurysm ruptures, fenestrated stent grafting (SG) and SG combined with arch debranching were performed. In all cases of TAI, aortic injuries occurred near the isthmus and 5 patients received fenestrated SG. The initial success rate was 100% and there was no perioperative death. Mean duration of observation was 24 months, which revealed 4 late deaths. The causes of late death were liver failure, cerebral contusion, senility and unknown. A patient with RTAA experienced a type III endoleak as an aorta-related event 24 months after operation. There was no enlargement of aneurysm in any patient. TEVAR for aortic catastrophes seems to be performed safely with acceptable outcomes. Although morphological incompatibility, unstable preoperative haemodynamics and longer time for preparation may become impediments to perform TEVAR, we believe that TEVAR should be the 1st choice for life-threatening aortic catastrophes. However, a careful follow-up is necessary because TEVAR has several unique late complications.

Apico-brachiocephalic artery bypass for aortic stenosis with porcelain aorta.

Apicoaortic bypass for left ventricular outflow tract obstruction has been performed with acceptable mid-term mortality. However, sometimes it is difficult to anastomose the distal end of the conduit to the calcified descending aorta in patients with a porcelain aorta. We report an aortic non-touch modification of the apicoaortic bypass in an 80-year-old woman with valvular aortic stenosis and a porcelain aorta extending from the ascending to abdominal aorta. We performed apico-brachiocephalic artery bypass under circulatory arrest with deep hypothermia. This procedure may become a useful surgical option for patients with a severe porcelain aorta.

Accessory mitral valve causing left ventricular outflow tract obstruction in an adult.

Accessory mitral valve (AMV) is a rare congenital abnormality that, rarely, causes left ventricular outflow tract (LVOT) obstruction in adults. We report the case of a 47-year-old man with deteriorating exertional dizziness. Evaluations revealed that the left ventricular outflow tract obstruction was caused by the accessory mitral valve. The patient underwent a successful operation for removal of the accessory mitral valve.
