Between Feb. 1992 and Apr, 1995, the authors have performed arthroscopic abrasion arthroplasty in 78 knees of 76 patients with degenerative osteoarthritis. The followup period was between 24 and 58 months, with on an average of 41 months. All patients had Zarins grade IV articular cartilage change. The results were as follows. 1. Of the total 78 knees, results were excellent in 25(32%), good in 33(42A), fair in 12(17%), poor in 8(10%) knees respectively. 2, The best results were obtained patellofemoral abrasion arthroplasty. 3. The poor results were obtained in patients with the both femoral condyle, lesion. 4. The results were much better in young age group (below 40 years). Aroscopic abrasion arthroplasty is not a curative but palliative method. But it could be an appealing altemative to total knee arthroplasty or high tibial osteotomy or can be performed postoperated after these reconstructive proeedures.

A clinical analysis was performed on 61 cases of patent ductus arteriosus experienced at Yeungnam University Hospital during 3 years period from April, 1984 to December, 1986. Of the 61 patient of PDA, 13 patients were male and 48 patient were female and age ranged 2 months to 26 years old with the average age of 9.4 years. The chief complaints on admission were frequent URI and dyspnea on exertion. diagnostic procedure were Doppler echocardiogram (in 53 among 61). Three postoperative complication were developed, but there was no operative mortality.

Ventricular septal defects is most common congenital cardiac anomaly in Korea and worldwide. And its clinical spectrum is well known. The anatomic classification had been undertaken by several authors, but recently Dr. Soto and Anderson's classification is widely used instead of Dr. Kirklin's it. From April, 1984 to December 1986, 99 cases of ventricular septal defects had been taken surgical repair under direct vision using conventional cardiopulmonary bypass technique at Yeungnam university hospital. The clinical spectrum was similar to other hospital, and postoperative mortality was 2%, the most common associated anomaly was patent foramen ovale, and the most common postoperative complication was incomplete or complete right bundle branch block. The rank of defects was as followings: 45 perimembranous inlet type, 21 doubly committed subarterial type, 17, perimembranous trabecular type, and 16 perimembranous outlet type. There was no muscular and mixed type.

During 1986, 111 cases of open heart surgery were performed at Yeungnam University Hospital consisting 88 cases of congenital heart disease and 23 cases of acquired heart disease. Among 88 congenital heart disease, 72 were acyanotic group and 16 were cyanotic. Common congenital heart diseases were ventricular septal defect (51%), atrial septal defect (18%) and Tetralogy of Fallot (16%). Among 23 acquired heart disease, 22 cases were valvular heart disease and one was dissecting aortic aneurysm. Three cases of the postoperative death were present resulting 2.7% of surgical mortality rate.

A 60-year-old man with advanced esophageal cancer was admitted for surgical placement of a feeding jejunostomy tube before commencement of chemoradiotherapy. His esophageal cancer had directly invaded the posterior tracheal wall, inducing a nearly total obstruction of the distal trachea. On the day before the surgery, respiratory failure developed due to tumor progression and tracheal edema. Tracheal intubation and mechanical ventilation were attempted without success. Application of veno-venous extracorporeal membrane oxygenation (ECMO) corrected the patient's respiratory acidosis and relieved his dyspnea. With full ECMO support, he underwent tracheal stent insertion. Two hours later, he was weaned from ECMO support uneventfully. This was a successful case of tracheal stenting for airway obstruction under rescue veno-venous ECMO.

The Graf stabilization has been introduced in treating lumbar spinal disorder associated with posterior instability. This study reviewed some problems of the Graf instrumentation as a soft stabilizer. The purpose of this study is to analyse the problems of the soft stabilization in spinal instability. We reviewed 145 cases which were operative treatment using the Graf instrument for lumbar spinal disorder associated with posterior instability at our department from May, 1991 to Dec, 1995. The mean follow up periods was 29 months ranging from 24 months to 6 years 8 months. Of the 145 cases, 22 cases were showed the problem. The diagnostic method were simple x-ray, flexion-extension lateral stress view and CT scan. Results were as follows : Adjacent segmental instability was 10 cases(6.9%), disc space narrowing was 8 cases(5.5%), screw loosening was 3 cases(2.1%) and breakage of the Graf band was 1 case(0.6%). The problems of the soft stabilization were adjacent segmental instability, disc space narrowing, screw loosening, and breakage of the Graf band. But the rate of adjacent segmental instability and disc space narrowing was lower than other lumbar spinal instrumentation.

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.

The purpose of this study was to evaluate the influence of high dose carbon tetrachloride (CCI4) on the hepatotoxic effect of dimethylnitrosamine (DMN) which induces acute hemorrhagic necrosis in liver. Rats were injected intraperitoneally DMN dissolved in physiologic saline by a dose of 40 mg/kg. For changes related to CCI⁴ pretreatment, rats were injected intraperitoneally CCI⁴ dissolved in olive oil by a dose of 0.4 mg/kg, and then injected DMN. The livers were extracted from the rats 3, 6, 12, 24, 48, 72, and 120 hours after CCI⁴ and/ or DMN injection. Liver tissues were examined with light and electron microscopes. The results were summarized as follows; Light microscopic findings: Severe centrilobular hemorrhagic necrosis developed from 12 hours after injection of DMN and continued to 120 hours. On injection of DMN after CCI4 pretreatment, Massive necrosis occurred early. But active regenerative changes were produced in 24 hours. In 120 hours, the liver recovered in almost normal appearance. The degree of necrosis in pretreated group was similar to that in DMN injection only, and the time of recovery was faster in pretreated group. Electron microscopic findings: The early change was mainly disorganization of RER in DMN injection, and clumping and vesicular dilatation of ER in injection of CCI4. In pretreatment group, the early change was similar in appearance with CCI4 group, but severer in degree. According to the results, it was revealed that acute toxic effect of DMN was recovered more rapidly in pretreatment group. Thus it was suggested that CCI4 had protective effect in DMN hepatotoxicity.
