Stereotactic radiosurgery, including gamma knife radiosurgery (GKS), can in rare cases result in de novo cavernous malformations (CMs). Here, we present a case of de novo CM induced by GKS following treatment of a cerebellar arteriovenous malformation (AVM). A 48-year-old woman was diagnosed with left unilateral Moyamoya disease. Conventional cerebral angiography also revealed an AVM in the left cerebellum. The patient underwent GKS using a 50% isodose of 15 Gy at the margin of the left cerebellar AVM. Magnetic resonance imaging (MRI) taken 3 years after GKS revealed small chronic hemorrhages with perilesional edema in the left cerebellum. Five years later, the lesions became aggravated, but were asymptomatic. Eight years following GKS, the patient was admitted complaining of headache and dizziness. Brain MRI revealed a 1.3cm hemosiderin deposit with an inner hyperintense nodular portion that was enhanced in the left cerebellum. An open craniotomy was performed and the mass was removed, from which pathological findings were compatible with those for CM. The patient recovered to the prehemorrhagic state. This case shows that De novo CMs can rarely develop after radiosurgery. Most CMs have been reported to develop following radiosurgery for brain tumors. As shown in this patient, CMs can also develop after radiosurgery for cerebellar AVM in adults.

Kidney Transplantation*

The surgical technique of renal transplantation has been well established, but surgical complications are not uncommon and still be important factors in postoperative mortality and morbidity. From August 1990 to May 1998, we performed 250 consecutive renal transplantations at Maryknoll hospital. The authors analyzed the kinds and incidences of surgical complications in a single center by using information from hospital records. The results were as follows: 1. The overall surgical complication rate was 9.6% (24 episodes in 250 cases). 2. These were composed of 6 vascular, 8 urologic, 4 lymphatic, and 6 wound complications. 3. Vascular complication included renal artery stenosis in 1 case and bleeding and hematoma in 5 cases. 4. Urologic complication included urine leakage in 4 cases, ureter stenosis in 2 cases and bladder stone in 2 cases. 5. Lymphatic complication was all lymphoceles. 6. One case in which renal artery stenosis had occured progressed to graft loss after 4 years later. There was no complication related mortality. 7. 1 year, 3 year and 5 year graft survival rate was 97.2%, 94.8% and 90.0%, respectively. and patient survival rate was 98.0%, 95.6% and 94.7%, respectively.

Infantile lobar emphysema is an uncommon disease affecting newborns and infants with varying degree of respiratory distress, lobar overaeration, mediastinal shift and herniation. Although the etiology of the condition is most commonly idiopathic, there is a clear association with congenital heart disease, particularly in the presence of pulmonary hypertension due to left to right shunt. Sites of predilection are the left main bronchus, the left upper and right middle bronchi. This report describes a two-week-old boy who had right middle lobe emphysema with large ventricular septal defect. At first, patch closure of perimembranous ventricular septal defect was performed. Postoperatively, the patient required continuing assisted ventilation and the lobar emphysema was not improve. One week following the initial operation, right middle lobectomy was successfully performed and the patient was weaned from artificial ventilator on the 5th postoperative day. The patient was discharged with good general condition on the 45th postoperative day.

Cor triatriatum is a rare congenital heart disease that is often lethal in children if not correctly identified and properly managed, Characteristically an anomalous membrane divides the left atrium into two chambers one located posterosuperiorly which is connected to the common pulmonary venous trunk and the other anteroinferiorly which is connected to the left atrial appendage and the mitral valve. Eight patients with Cor triatriatum were been seen at our hospital from 1984 to 1999. The clinical presentation diagnostic evaluation and surgical results are outlined in this retrospective review. Resection of the obstructing anomalous atrial membrane was performed using a hypothermic cardiopulmonary bypass in all cases. Right atriotomy was performed in all patients and left atriotomy was performed in a patient who had poor preoperative general conditions and serious cardiac defects(TAPVR & hypoplastic left ventricle) died of low cardiac output during the immediate postoperative period. The postoperative course has been excellent in the remaining. Cor triatriatum is amenable to surgical repair with excellent results when diagnosed early and in those who are not complicated by other complex cardiac anomalies.

Leiomyoma is extremely rare benign tumor of the trachea. A case of leiomyoma of the trachea is described in a 36-year-old man. The patient had a brief history of asthma-like symptoms. Computed tomography of the chest revealed the ovoid lower trachea mass, which was occupying about 80% of the tracheal lumen. At fiberoptic bronchoscopy highly vascularized round mass was seen on the membranous portion of the lower trachea. The tumor was excised by segmental sleeve resection and end-to-end anastomosis of the trachea was performed. Postoperative course was uneventful and bronchoscopic findings showed clear healing of the anastomotic site.

Sclerosing hemangiomas are rare benign neoplasms in pulmonary parenchyme, We analyzed CT findings of two cases of sclerosing hemangiomas of the lung in two adult females. Chest radiograph showed well-circumscuribed, round soft tissue mass with calcification in right lower lobe of one patient and without calcification and moderate or marked contrast enhancement was clearly demonstrated with CT scan. CT findings of contratst enhancement and contour of calcification allow differentiation of sclerosing hemangioma from other venign neoplasms or postinflammotory pseudotusrs of the lung.
