Hemangioma are not rare tumor, they are found in almost all the vascular structures of the body. They are fairly common in the akeletal muscles. There Is no unanimity of opinion concerning the etlology and pathogenesis of hemangioma. It Is most llkely, however, that hemangioma are congenital in origin. The authors have experienced unusual huge skeletal hemangioma occurred in forearm and hand in infant. These huge hemangioma in infant ls very difficult to excise completely with the conventional methods. But we have obtained the excellent result by using recently advanced meticulous microsurgical technique.

It is notoriously difficult to obtain a sound bony union of congenital paeudarthrosis of tbe tibia with conventional methods. This paper is the results of using the free vascularized fibular graft for congenital pseudarthorsis of the tibia in 7 patients since 1978 in this hospital, which is the first attempt in Korea. During the follow-up periods from 9 months to 32 months, 5/7 patients(71%) had good or excellent bony union, 2 patients had bone resorption at tbe distal site of grafted bone and required a second supplementary cancellous bone graft with electrode insertion. So it is thought that the free vascularized fibular graft is one of good methods of treatment for congenital pseudarthrosis of the tibia.

An arteriovenous fistula may be defined as a vascular abnormality in which there are one or more direct or indirect communication between an artery and a vein without any intervening capillary bed. Largely, such fistulas are divided into two groups-acquired (traumatic) or congenital in origin. There is a general agreement that congenital A-V fistula results from a failure in differentiation of the common embryonic anlage into true artery and vein. The authors have experienced a case of congenital A-V fistula formed in the 4th finger of the left hand. Such fistula is very difficult to excise completely with the conventional method. But we have obtained the excellent result by utilizing advanced meticulous microsurgical technique in excision.

In view of the problems with infection, traditional orthopedic teaching has held that the use of metalic fixation in open fractures is contraindicated. But the bone shortening and internal fixation of amputated limb is a principle for replantation. The authors experienced 23 patients of replanted limbs including femur, tibia, humerus, radius and ulnar among total 142 replantations and also analysed them in the respect of the relationship among soft tissue injury, fixatives, bone union and infection rate from February, 1975 to July, 1981 in this department. The rate of delayed union, nonunion and infection were 22.6%, 6.5% and 25.8% respectively. It seems that the union process of bone in replanted limbs is similar to that of the open fracture and also rigid internal fixation is the most useful for bony union.

A case of the brain death confirmed by isotope angiogrphy is described. Isotope angiography is a simple and noninvasive technic compared to carotid angiography, and is recommended as a reliable test for the diagnosis of brain death.

PURPOSE: Pediatric cardiac arrhythmias are increasing but there is no normal values of cardiac electrophysiologic studies(EPS) in Korean children. So we performed cardiac EPS in children undergoing cardiac catheterization for mild congenital heart disease without cyanosis and ECG abnormality. METHODS: We studied 24 children(male : 9, female : 15) with mild congenital heart disease(PDA : 10, VSD : 8, ASD : 6, age range 1.8 years to 9.3 years, mean 4.3 years). All studies were performed under propofol intravenous anesthesia. Fifteen minutes after cardiac angiography, two elctrophysiologic catheters were inserted through the right femoral vein into the right atrial appendage and His hundle area. Using atrial pacing with various cycle lengths for 30 seconds, we evaluated the sinus node recovery time(SNRT) and corrected sinus node recovery time(CSNRT) and atrioventricular block cycle length(AVBCL). Using atrial extrastimuli during sinus rhythm and paced 8 atrial rhythm, we evaluated the atrioventricular node effective refractory period(AVNERP) and total sinoatrial conduction time(TSACT). RESULTS: Baseline sinus cycle length was 661 +/- 107 msec. SNRT and CSNRT were 955 +/- 181 msec, 264 +/- 68 msec each. AVBCL and AVNERP were 365 +/- 56 msec, 264 +/- 63 msec each. TSACT was 220 +/- 55 msec. CONCLUSION: Considering the importance of pediatric cardiac arrhythmias, we have to have the normal EPS values in Korean children. But it is impossible to perform a invasive EPS for normal children without heart disease. So we believe that these measured values in children with mild congenital heart disease may be used as the normal value in Korean children.
