Major peripheral arterial graft infection is a potentially devastating complication of vascular surgery, associated with significant mortality and high amputation rates. Autologous saphenous veins are considered optimal arterial conduits for lower extremity revascularization in infected fields, but they are often unavailable or unsuitable in these patients. This study describes two patients with major peripheral graft infection, but without available autologous veins, who underwent graft excision and cryopreserved cadaveric arterial allograft reconstruction. Although long-term graft durability is unclear because of gradual deterioration and degeneration, these findings suggest that cadaveric allografts may be good options for patients with major peripheral graft infection.

BACKGROUND: Glomus tumors were first described by Wood in 1812 as painful subcutaneous tubercles. It is an uncommon benign neoplasm involving the glomus body, an apparatus that involves in thermoregulation of cutaneous microvasculature. Glomus tumor constitutes 1%-5% of all hand tumors. It usually occurs at the subungual region and more commonly in aged women. Its classical clinical triad consists of pain, tenderness and temperature intolerance, especially cold sensitivity. This study reviews 15 cases of glomus tumor which were analyzed according to its anatomic location, surgical approach and histologic findings. METHODS: Fifteen patients with subungual glomus tumors of the hand operated on between January 2006 and March 2013, were retrospectively reviewed. Patients were evaluated preoperatively with standard physical examination including ice cube test and Love's test. Diagnostic imaging consisted of ultrasonography, computed tomography, and magnetic resonance imaging. All procedures were performed with tourniquet control under local anesthesia. Eleven patients underwent excision using the transungual approach, 3 patients using the volar approach and 1 patient using the lateral subperiosteal approach. RESULTS: Total of 15 cases were reviewed. 11 tumors were located in the nail bed, 3 in the volar pulp and 1 in the radial aspect of the finger tip. After complete excision, patients remained asymptomatic in the immediate postoperative period. In the long term follow up, patients exhibited excellent cosmetic results with no recurrence. CONCLUSIONS: Accurate diagnosis should be made by physical, radiologic and pathologic examinations. Preoperative localization and complete extirpation is essential in preventing recurrence and subsequent nail deformity.

BACKGROUND: A stenosis of left main coronary artery has critical prognostic importance. Recent reports on successful left main stenting are now challenging traditional treatment patterns for this lesion. We evaluated recent four-year trends in incidence, clinical, angiographic findings and treatment modalities in patients with left main coronary artery stenosis(LMS). METHODS: Patients who were diagnosed as a significant LMS at Yonsei cardiovascular hospital between 1996 and 1999 were analyzed retrospectively. RESULTS: The incidence of LMS during the period of 1996 to 1999 was 3.3%(n=24) and it was significantly higher than that of previous 15 years before 1996(p<0.01). The incidence of isolated ostial lesion was 0.28% and this lesion was more prevalent in young female patients with less risk factors compared with other types of LMS(p<0.01). After exclusion of the patients with an isolated ostial lesion, patients were grouped according to the lesion site: ostium, shaft, and shaft lesion extended to distal vessels. There were no differences in clinical and hemodynamic findings among these groups. Coronary artery bypass graft was performed in 141 patients(63%) and stent implantation in 16 patients(14%). CONCLUSION: The incidence of LMS has been increased. There was no difference in clinical and hemodynamic findings according to the types of LMS. Surgery is still a standard treatment, but in selected patients percutaneous coronary intervention can be another treatment option.

Cerebrovascular accident remains the second most common cause of death in Korea, following combined cancer mortality. It is one of the most common causes of disability, and atherothromboembolic ischemic infarction accounts for nearly half of stroke in Korea. Carotid endarterectomy is proven to be effective in preventing stroke from internal carotid artery stenosis. The authors report the results of prospective study of 63 carotid endarterectomies, performed from September, 1995 to November, 1997 at our institution, to clarify the persisting diversity of opinions as to ideal preoperative diagnostic tests, anesthetic management, intraoperative monitoring techniques for cerebral protection, type of arterial repair, and postoperative evaluation for cerebral function. We confirmed that preoperative diagnostic tests of duplex scanning and magnetic resonance angiogram can replace the invasive conventional cerebral angiography, and observation of consciousness under regional anesthesia is the most reliable and safe method for carotid endarterectomy utilizing selective shunting, if needed.
