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.

PURPOSES: Transurethral resection of the prostate (TURP) for symptomatic benign prostate hyperplasia (BPH) remains a gold standard for surgical treatment, but significant morbidities are associated with the procedure. Transurethral electro-vaporization of prostate (TVP) using a grooved ball electrode, a modification of standard TURP, was tried on bladder outlet obstruction in an attempt to reduce the morbidity rate of TURP. We compared between the TVP and standard TURP to estimate the efficacy and safety. MATERIALS AND METHODS: A comparative trial of 44 patients with symptomatic BPH from May 1995 to December 1995 was performed. Of the patients 20 were received operation with TVP (Group I) and 24 were received with standard TURP (Group II). Patients were assessed at baseline for both safety and efficacy and in follow-up at 1 and 3 months. Efficacy parameters evaluated included American Urological Association (AUA) symptom score, peak urine flow (Qmax) and postvoid residual urine (ml). Safety parameters evaluated included incidence of side effects, operative time (in minutes), postoperative catheterization time, change in hematocrit and serum sodium. RESULTS: The mean age of each group was 63.7+-6.4 years (Group I) and 68.8+-7.6 years (Group II), the prostate size was 32.4+-3.4g and 34.5+-6.5g. The mean operation time was shorter in Group I (56+-11min) than Group II (85+-34min), (P<0.05). The change of Hematocrit(ml/dl) was lower in group I (from 41.1+-5.0 to 39.5+-4.2) than group II (from 39.6+-4.4 to 35.2+-5.5), (P<0.05). The mean catheterization time was 3.3+-1.3 days and 4.8+-1.7 days, (P<0.05). change of maximal flow rate, post-void residual volume and AUA symptom score was not significantly different between each group. The incidence of postoperative complications were not significantly different between each group. CONCLUSIONS: Although the TURP is the gold standard for the treatment of symptomatic BPH with high success rate, but significant morbidities rate are associated with this procedure. So, TVP is new and potentially useful modification of TURP. In this preliminary study, there has been significant clinical improvement maintained with minimal morbidity. This early clinical experience highlights several potential advantages of TVP, including rapid convalescence time, short hospital day, and minimal blood loss. So, TVP is one of the various therapeutic alternatives for BPH lowering the morbidity rate of standard TURP.

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 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.
