Long term follow-up study was done on 38 cases of anterior fusion for spinal tuberculosis especially about effect of buttress graft. The average follow-up period was 16 months. 14 cases of effective buttress group were appeared' to achieve more rapid bony union and prevent further kyphosis or lateral wedging of the involved vertebral body than inadequate buttress group of 7 cases.

PURPOSE: The purpose was to evaluate the procedure-related complications of the TIPS and its clinical significance. MATERIALS AND METHODS: The materials consisted of 52 patients who had 57 TIPS procedures for the management of variceal bleeding due to portal hypertension. To detect the occurrence of complications during transhepatic needle puncture(from hepatic vein to the portal vein), contrast material was injected with the withdrawl of the puncture needle. RESULTS: Procedure-related complications occurred in 28 patients (54%) among 52 patients. The corn lications were biliary tree puncture(15 cases), transperitoneal puncture(14 cases), stent malposition(3 cases) stent migration(1 case), hepatic arteries puncture(1 case), splenic vein perforation(1 case), and paroxysmal tricular tachycardia(1 case). Three patients had acute stent thrombosis with rebleeding immediately after procedure. The procedure was repeated in two patients. One patient was expired due to rebleeding. CONCLUSION: The procedure related complications were clinically insignificant in most instances, when stent thrombosis or proxysmal ventricular tachycardia was developed.

It has been reported in autopsy that most of the patients with Korean hemorrhagic fever had necrotic areas inthe anterior lobe of the pituitary gland. The high resolution CT of sella was performed to demonstrate thepossible pituitary necrosis in consecutive 13 patients with Korean hemorrhagic fever. Only 3 patients demonstrate normal sellar findings. Ten (77%) out of 13 cases reveal abnormal findings; 2 patients show typical empty sellar and the rest (8 patients) reveal localized low denstiy area in the anterior portion of the sella turcica, which may be from partial empty sella, pituitary infarction or other unknown pathology. The low denisties within the sella will be discussed.

Four patients were treated who had limited flexion of the hips and various degrees of contracture of the abduction and external rotator muscles because of fibrosis of the gluteus maximus muscle. Each patient had a typical restriction of motion such that an affected hip could not be flexed in the usual sagittal plane, but had to be flexed in abduction. Genetic, congenital and postnatal factors have been suggested as the cause of fibrosis of gluteus maximus muscle. Three of the 4 patients reported here are of congenital origin and another one is of postnatal factor repeated intramuscular injections. Excellent correction of the hip contracture was achieved in all patients by division of the fibrotic bands.

PURPOSE: The purpose of this study was to assess the usefulness of MRI in the evaluation of vascular changes of the meningioma. MATERIALS AND METHODS: We retrospectively studied the MRI findings in 20 cases of intracranial meningiomas. The images were assessed for vascular hilum, vascular rim, sinus invasion, and vascular encasement. Cerebral angiograms were obtained in 15 cases and compared with MRI findings. RESULTS: MRI was as accurate as angiography in detection of vascular hilum(MRl=8/20, Anglogram=9/15), vascular rim(MRl=14/20, Angiogram=9/15) and dural sinus invasion(MRl=4/6, Angiogram=5/6). MRI was superior to angiography in detection of vascular encasement(MRl=2/3, Angiogram=0/2) and cavernous sinus invasion(MRI=3/3, Angiogram=0/2). CONCLUSION: MRI is an excellent noninvasive imaging modality in evaluating vascular changes of omas.

10.Technical Tips for Performing Suprahepatic Vena Cava Tumor Thrombectomy in Renal Cell Carcinoma without Using Cardiopulmonary Bypass

Radical nephrectomy with tumor thrombectomy for advanced renal cell carcinoma is an oncologically relevant approach that can achieve long-term survival even in the presence of distant metastases. However, the surgical techniques pose significant challenges. The objective of this clinical review was to present technical recommendations for tumor thrombectomy in the vena cava to facilitate surgical treatment. Transesophageal echocardiography is required to prepare for this procedure. Cardiopulmonary bypass should be considered when the tumor thrombus has invaded the cardiac chamber and clamping is not feasible because of the inability to milk the intracardiac chamber thrombus in the caudal direction. Prior to performing a cavotomy, it is crucial to clamp the contralateral renal vein and infrarenal and suprahepatic inferior vena cava (IVC). If the suprahepatic IVC is separated from the surrounding tissue, it can be gently pulled down toward the patient’s leg until the lower margin of the atrium becomes visible. Subsequently, the tumor thrombus should be carefully pulled downward to a position where it can be clamped. Implementing the Pringle maneuver to reduce blood flow from the hepatic veins to the IVC during IVC cavotomy is simpler than clamping the hepatic veins. Sequential clamping is a two-stage method of dividing thrombectomy by clamping the IVC twice, first suprahepatically and then midretrohepatically. This sequential clamping technique helps minimize hypotension status and the Pringle maneuver time compared to single clamping. Additionally, a spiral cavotomy can decrease the degree of primary closure narrowing. The oncological prognoses of patients can be improved by incorporating these technical recommendations.
