From January 1983 to December 1992, 116 patients under 10Kg of body weight were underwent open heart surgery in National Medical Center.There were 64 males and 52 females, and their mean age was 14 2.6 months, ranged from 3 days to 38 months. Their mean body weight was 7.4$\pm$1.2Kg, ranged from 2.4Kg to 10Kg which were less than 3 percentile of normal developmental pattern in 109 out of 116 cases.The composition of the patients was VSD[73 , TOF[18 , ASD[8 , ECD[5 , TGA[4 , PS[3 , TAPVC[2 , TA[1 , cardiac rhabdomyoma with ASD[1 , and Ebstein`s anomaly[1 . The overall surgical mortality was 17.2%.In acynotic group, 11 patients died among 91 patients and the mortality was 12.1%, in cyanotic group 9 patients died among 25 patients, the mortality was 36%.The surgical result of patients under 5Kg of body weight was worse than those over 5Kg of body weight. [56.2% versus 11% The surgical result in this period was improved year by year, but poor surgical results in the group of cyanotic, under 5Kg of body weight should be improved by means of more precise preoperative diagnoses, more advanced surgical techniques and more proper postoperative management.

Objective: Aneurysms arising from the posterior inferior cerebellar artery(PICA) are uncommon. We review literature on that and surgical results on aneurysmal treatment by choice of surgical approach. Methods: On the basis of radiologic findings & charts, we review retrospectively the surgical results of 12 cases from Mar 1999 to Dec 2003. Results: The mean age of the 12 patients was 55.8(ranged from 36 to 71) and female was predominant (female:male = 8:4). Locations of PICA aneurysms revealed variously(vertebral artery - PICA junction: 8, lateral medullary segment: 2, PICA - anterior inferior cerebellar artery common trunk: 1, telovelomedullary : 1). Surgical approaches & treatments were attempted in 11 cases and embolization was done in 1 case(Far lateral transcondylar or supracondylar approach & clipping: 9, Far lateral transcondylar or supracondylar approach and trapping: 2, suboccipital approach & clipping: 1). The surgical result were 8 of 12 patients were good outcome, 1 of 12 was severely disabled and 3 of 12 were died. Conclusion: First, we choose surgical approach by the laterality of aneurysms and surgical or interventional treatment is attempted as soon as possible. The PICA aneurysm is regarded as having a relatively good surgical outcome without drilling of the posterior arch of the atlas.

The results of surgical experience of double outlet right ventricle with pulmonic stenosis in 14 patients are reported. Among the 14 patients, 8 underwent the intraventricular tunnel repair with the result of 3 hospital deaths, 5 had Fontan type operations due to the various anatomic reasons and resulted in one hospital death, and the remaining one patient had palliative pulmonary valvotomy. Besides the problems related to the effective relief of the pulmonic stenosis, double outlet right ventricle with pulmonic stenosis may present a surgical challenge because severe associated anomalies which definitely complicate their repair are not uncommon. We describe the anatomic details of our 14 cases of DORV with PS and the surgical results. The results having been unsatisfactory, more meticulous diagnostic studies for the detailed intracardiac morphologies and the strict indication for their repair with the refinement of surgical technique seem necessary for the better surgical results.

Purpose : The aim of this study was to compare surgical complications between simple implant placement and implant placement combined with complicated surgical procedures. We also evaluated prosthetic complications according to the specific types of prosthesis. Material and Method : A retrospective analysis of dental chart of patients who was performed implant therapy during the period from June 2003 to December 2005 was carried out. This study was performed on 408 patients (208 male, 200 female). In addition, 1671 implants were performed. Based on their medical record and radiographs, the authors evaluated surgical and prosthetic complications, surgical procedures accompanied at the time of implant, risk factors of implant failure etc. Result : Surgical complications were developed on 358 implants(21.4% on total placed implants) and wound dehiscence was most prevalent complication. On maxillary posterior area, surgical complications developed more frequently on implants with major surgery and showed a significant difference. And complication rate of implants accompanied with GBR was higher than that of simple implants placement and also showed significant difference. The implant supported prosthesis showed no statistical difference in the occurrence of complications according to the types of prosthesis, and food retention was the most common post-prosthetic complication. Also we speculated that length and width of implant showed significant correlation to the failure of implant primary osseointegration. Conclusion : Based on the result, clinician should provide more careful maintenance for patients with implant placement accompanied by complicated surgical procedure. And periodic maintenance for the patient is requested for long-term survival of implant therapy.

Congenital defects of the sternum are rare development anomalies. They result form the failure of the lateral sternal bars to fuse. This malformation may be associated with other ventral midline fusion defects and ectopia cordis. A complete sternal cleft is the rarest form and less than 10 cases have been reported in the medical literature. Here were report a 3-day-old boy with complete sternal cleft without other malformations, who underwent primary surgical repair. Surgical correction of complete sternal cleft should be performed in neonatal period whether the infant if symptomatic or not because it is usually simple, able to achieve good result and primary repair is usually feasible at this period.

In EVAR procedure using long time C-arm, we studied exposure dose reduction and effeciency through measuring surgical staff's ESD by installing lead curtain operating table next to. The height 3 the spot (50cm, 100cm, 150cm) dose was measured on 2 locations for 600sec in the X-ray radiation considering the surgical staff's movement. To install the curtains, we compared before and after the dose. As a result, it can confirm that dose of the installation former of 50cm height and after is reduced about 75% and 91% in 2 locations. In 100cm height, the reduction of the dose was a bit confirmed. There as to dose value, measured on 150cm height the installation former and after was nearly no change. This research examined the exposure dose about the radiation of the surgical staff during EVAR procedure in which the operation time is the long time. It was implemented in the object that it reduces the radiation exposure. It could confirm the certain effect of the experimental result exposure dose reduction In EVAR procedure using long time C-arm, we studied exposure dose reduction and effeciency through measuring surgical staff's ESD by installing lead curtain operating table next to.

There has been arguing in the proper surgical treatment of myasthenia gravis. But the ultimate goal of operation is complete removal of thymic tissues. In view of previous surgical-anatomic studies that there are frequently thymic tissues from the level of thyroid gland to the diaphragm and from hilum to hilum, en bloc resection of thymus, mediastinal fat including both sheets of pleura and pericardium is reasonable. We experienced four myasthenic patients with radical thymectomy from 1989. As compared to the result of previous simple thymectomy group, the 23 patients who were operated from 1976 to 1988[Group I ], excellent surgical outcome was obtained in radical thymectomy group[Group II ].
