A 58 year-old man presented with a large aneurysm of the aortic arch and severe coronary artery disease. He underwent combined repair of the aortic arch aneurysm and coronary artery bypass grafting via a modified clamshell incision using deep hypothermic circulatory arrest and retrograde cerebral perfusion. He made an uncomplicated postoperative recovery. The operative techniques are discussed ...
The 5-aminolevulinic acid (5-ALA)-induced tumor fluorescence is a useful intraoperative marker for the diagnosis and the detection of various malignancies, but its use in meningioma is only reported infrequently. In meningioma, a complete resection of the tumor mass is crucial for the prevention of recurrence and postoperative morbidities. Deep sylvian meningioma is a rare type of meningioma wh...
We studied 8 patients with cerebral infarction in the deep territory of the middle cerebral artery (MCA). All patients had a definite cardiac source of emboli and no known factors for thrombosis. Mixed sensory and motor deficit was found in all but one patient and CT scan showed larger lesions than usually reported in lacunar infarcts. Contrast enhancement was seen in all cases in which CT scan...
OBJECTIVE This study was designed to evaluate the serial haemodynamic changes during coronary artery anastomoses using two deep pericardial stay sutures and octopus tissue stabilizer in patients undergoing initial experiences of off-pump coronary artery bypass graft surgery (OPCAB) using continuous cardiac output and mixed venous oxygen saturation (SvO(2)) monitoring. METHODS With IRB approva...
BACKGROUND AND PURPOSE This study was conducted to elucidate the association between clinical and angiographic characteristics and stroke types in adult Moyamoya disease that has been rarely evaluated. MATERIALS AND METHODS We analyzed the clinical and radiologic data obtained from a retrospective adult Moyamoya disease cohort with acute strokes, which were classified into 7 categories: large...
Patients with porcelain aorta carry a high risk of cerebral as well as systemic embolism during cardiac surgery. Here we describe a case of severe aortic stenosis and coronary artery disease combined with the circumferentially calcified aorta. The patient was a 77-year-old man who successfully received four coronary artery bypass grafts with in situ arterial grafts without clamping the aorta an...
Purkayastha et al reported 3 cases of proatlantal intersegmental arteries of external carotid artery origin associated with Galen’s vein malformation; however, because of their configuration, I believe that the 3 cases do not demonstrate this rare arterial variation, but rather show collateral blood flow from the occipital artery (OA) to the vertebral artery (VA). In patients with a vein of Gal...

The anatomical variations in the arterial supply of the palm are frequently reported. One such variation reported during routine dissection for undergraduate medical students in our college is the absence of superficial palmar arch and presence of persistent median artery. The arterial supply to the palm is in the form of superficial and deep palmar arches. In the present case the median artery...
Superficial inferior epigastric artery (SIEA) flap salvage remains challenging, particularly in cases of arterial insufficiency due to vessel spasm, pedicle kinking, or thrombosis. The already small, short SIEA pedicle, in addition to its inherent tendency toward spasm, renders the SIEA flap more difficult to manage when anastomotic revision is required. Furthermore, arterial thrombosis will ca...
