Adventitial cystic disease (ACD) of venous system is an extremely rare condition. Very few reports of ACD in venous system have been described. In this report we discuss two cases of common femoral vein ACD that presented with a swollen leg by the obstruction of the vein. Ultrasound imaging showed the typical hypoechoic fluid filled cyst with a posterior acoustic window. Computed tomography scan and ascending venogram showed a stenosis to flow in the common femoral vein caused by an extrinsic mass. Trans-adventitial evacuation of cyst with removal of vein wall was performed for both cases. During operation we found the gelatinous material in the cysts arising in the wall of the common femoral vein and compressing the lumen. The patients were released after short hospitalization and have remained symptom free with no recurrence.

Congenital duodenal obstruction in the newborn infant may be due to a variety of causes. Duodenal obstruction often presents with bilious vomiting and upper abdominal distention. Diagnosis is usually established on plain x-ray of the abdomen by the classic finding of the double-bubble. In the period July 1986 to June 1990, 16 patients with congenital duodenal obstruction were operated and the following results were obtained. 1. Sixteen patients were comprised of 11 males and 5 females, the ratio of male and female was 2.2:1. 2. Thirteen patients (81%) had been admitted to our hospital during one month of life. 3. Congenital duodenal obstruction was in 16 cases; malrotation in eight (50%), annular pancreas in six (38%), type 1 atresia in one (6%), and wind-sock anomaly in one (6%). 4. There were two premature patients and six patients of small for gestational age. 5. Overall, bilious vomiting, occurring in three fourths, was the single most frequent presenting complaint. 6. Polyhydramnios occurred in two of the patients. 7. Diagnosis was possible with clinical symptom and simple abdomen. 8. The operative procedures performed were; duodenoduodenostomy in five, duodenojejunostomy in two, excision of wind-sock membrane in one, and Ladd's procedure in eight. 9. A total of ten associated congenital anomalies were found in six patients. 10. Postoperative complications occurred in five cases (31%).

The number of procedures performed annually for occlusive vascular disease continues to increase. Currently, approximately 500,000 patients undergo reconstructive vascular surgery each year; half of these procedures are coronary bypass procedures and the remainder include various operations on the peripheral vascular tree. These peripheral interventions encompass a wide assortment of procedures including autogenous and prosthetic bypass grafts, endarterectomies, and a variety of new endovascular procedures. Most established vascular procedures, as well as the new technologies and applications, have proven both technically feasible and safe. The value of any surgical procedure must be measured not only by the success by which it can be initially performed but also in terms of the durability of the results. Although in-hospital success rates are excellent, the long-term durability of most of these procedures has been disappointing. Furthermore, the common culprit accounting for much of the poor long-term success rate of these procedures is intimal hyperplasia. Clearly this process is a significant cause of morbidity in patients undergoing procedures on the vascular system, and investgations into methods to prevent or reverse this process are of great importance. Author evaluates incidence, cause and treatment procedures to correct restenosis and analyzes the results of these procedures in the fields of restenosis after peripheral bypass, carotid endarterectomy and endovascular surgery.

Though the occurrence of multiple primary malignant tumor is a rare finding but the reported cases of it has increased in recent years. We collected multiple primary cancer of different organ, tissue and the multicentric origin of bilaterally paired organs. This paper reports 6 cases of multiple primary malignant tumors which were experienced at Yeungnam university hospital in Taegu during the past 2 years with review of journals. The results were as follows. 1. The incidence of multiple primary cancer was 0.31% for 2 years (1987-1988). 2. The ratio between male and female was 1:1 and mean age of incidence was 54.1 years. 3. The ratio between synchronous and metachronous (interval more than 6 months) was 1:1. 4. The time interval between first and second cancer was average 2.7 years in metachronous cases. 5. The most frequent involved organ was stomach, breast and colon in order of frequency. 6. The incidence of familial cancer associations was found in one out of 6 cases. 7. The test of DNCB, multitest CMI and ratio of T4 to T8 were performed in 4 cases but there was no definitive evidence of abnormality. We concluded that every effort should be made to discover the presence of synchronous malignancies in the patients who are being treated for a known tumor, and also special care should be given to detect new metachronous lesions is required.

Calcium channel blockers are used for the management of hypertension or heart disease after organ transplantation and are known to increase in blood cyclosporine A(CsA) levels through an effect on the hepatic cytochrome P450 system resulting in reduced CsA clearance. Authors reviewed and analyzed 154 CsA-treated renal allograft recipients at Yeungnam University Hospital from Mar. 1985 to Mar. 1996 to evaluate the effects of calcium antagonists on renal recipient. Among 154 recipients, 60 recipients were received triple immunosuppressive drugs (CsA+Prednisolone+ Azathioprine) only (Control group), 43 recipients with diltiazem (D group) and 51 recipients with Nifedipine (N group). Blood pressure(systolic and diastolic), creatinine level, CsA blood level and CsA dose had been checked at 1 week, 1, 3, 6, 9 and 12 months, after renal transplantation serially and compared the results with each groups. CsA blood levels of all groups had been adjusted to 100-150 ng/ml after 3 month of immunosuppression. There was no difference in CsA blood levels among 3 groups at all follow-up periods. Dose reduction of CsA had been noted 18%, 27%, 29%, 32%, and 28% in D group at 1, 3, 6, 9 and 12 months respectively(p<0.05), In N group, CsA dose reduction had been noted 7%, 6%, 3%, 11% and 5% at 1, 3, 6, 9 and 12 months, but this results was not significant statistically(p>0.05). Incidence of primary nonfunction, graft loss, acute rejection, chronic rejection and CsA nephrotoxicity were not different statistically among 3 groups. In conclusion, the use of diltiazem was associated with a markedly reduced requirement for CsA without any adverse effect on graft function or graft outcome. but the use of nifedipine may not associated with repuirement for CsA statistically.
