A case report of lymphangiohemangioma of the mediastinum that was misdiagnosed as thymic origin mass on chest CT and MR angiography. Operative finding revealed vascular proliferation originated from innominate vein and the pathologic finding showed both lymphatic and vascular component which was diagnosed lymphangiohemangioma.

A newborn girl with a partial anomalous pulmonary venous connection, coarctation of the aorta, and ventricular and atrial septal defects underwent a complete repair successfully at 49 days of age. In this case, the left upper pulmonary vein was connected to the left innominate vein via an atypical vertical vein.

Sixteen-day-old baby with severe Ebstein anomaly underwent emergency operation to relieve progressive hypoxia and congestive heart failure. Operative findings showed huge right atrium and atrialized right ventricle (aRV) with very small functional RV by distal displacemcent of tricuspid valve mechanism. We elected to perform modified Starness operation because biventricular repair was deemed unattainable. After pulmonary and tricuspid valves were primarily closed, aRV was obliterated with multiple sutures from RV apex to the base. Then a PTFE (Gore-Tex, USA) vascular graft was interposed between innominate artery and main pulmonary artery for systemic to pulmonary shunt. The patient was discharged uneventfully, and received bi-directional cavopulmonary shunt 6 months later.

Background: Deep hypothermic circulatory arrest during repair of aortic arch anomalies may induce neurological complications or myocardial injury. So we surveyed if the regional cerebral and myocardial perfusion might eliminate those potential side effects. Material and Method: From March 2000 to December 2004, 62 neonates or infants with aortic arch anomaly underwent one stage biventricular repair using the regional perfusion technique by single surgeon. Preoperative diagnosis of the arch anomaly consisted of coarctation (n=46), interruption of the aorta (n=12), hypoplastic left heart syndrome (n=2) and truncus areteriosus (n=2). Combined anomalies were ventricular septal defect (n=51), TAPVR (n=1), PAPVR (n=1) and atrioventricular septal defect (n=2). Arterial cannula was inserted at the innominate artery. Result: The mean regional perfusion time of brain was $28{\pm}10min$. Operative mortality rates was 0 (0/62). Late death was 1 (1/62) during $11{\pm}7$ months of follow-up. Neurologic complications consisted of transient chorea in 1 case. There was no reoperation associated with arch anolamy. Pulmonary complication associated with arch repair occurred in f case which was managed by aortopexy. Conclusion: One-tage rch repair using the regional profusion is safe and effective in minimizing the neurologic and myocardial complications.

In this study, we estimated the PMP(Probable Maximum Precipitation) and its transition in case of the typhoon Rusa which happened the biggest damage of all typhoons in the Korea. Specially, we analysed the moisture maximizing rate under the consideration of meteorological condition based on the orographic property when it hits in Gangneung region. The PMP is calculated by the rate of the maximum persisting 12 hours 1000 hPa dew points and representative persisting 12 hours 1000 hPa dew point. The former is influenced by the moisture inflow regions. These regions are determined by the surface wind direction, 850 hPa moisture flux and streamline, which are the critically different aspects compared to that of previous study. The latter is calculated using statistics program (FARD2002) provided by NIDP(National Institute for Disaster Prevention). In this program, the dew point is calculated by reappearance period 50-year frequency analysis from 5% of the level of significant when probability distribution type is applied extreme type I (Gumbel distribution) and parameter estimation method is used the Moment method. So this study indicated for small basin$(3.76km^2)$ the difference the PMP through new method and through existing result of established storm transposition and DAD(Depth-Area-Duration). Consequently, the moisture maximizing rate is calculated in the moisture inflow regions determined by meteorological fields is higher $0.20{\sim}0.40$ range than that of previous study. And the precipitation is increased $16{\sim}31%$ when this rate is applied for calculation.
