The inferior vena cava (IVC) filter is known as an effective and safe method for preventing fatal pulmonary thromboembolism in patients with deep vein thrombosis. Usually, the remaining IVC filters are asymptomatic and do not cause clinical problems. We report a case of duodenal perforation caused by a remaining IVC filter.

Central venous catheterization via an internal jugular vein or subclavian vein has become a common procedure in monitoring CVP and managing severely ill patients. However, there have beennumerous reports of complications associated with central venous catheterization. These include vessel injury, pneumothorax, hemothorax, nerve injury, arrhythmias, arteriovenous thrombosis, pulmonary embolism, and infection at the insertion site. We report a case of hemothorax after subclavian vein catheterization failure, along with successful treatment.

No one technique provides an optimal outcome for all body contouring patients. There are many surgical options for abdominoplasty. Among these, this abdominoplasty without undermining consists of liposuction around abdominal subcutaneous fatty tissue, excision of lower abdominal flap. The procedure allows aggressive thinning and sculpting of abdominal flap. This operation minimizes the dead space, which often leads to postoperative complications, and preserves neurovascular supply to the abdominal skin. From 1999 to 2004, 18 patients underwent the abdominoplasty without undermining, resulting in high satisfaction rates with no significant complications, such as, pulmonary embolism and deep vein thrombosis. Patients could return to normal activity within a week. This abdominoplasty without undermining is an effective and safe alternative with low complication rate and enhances aesthetic results compared to traditional abdominal surgery.

During the 4 years period to be reported, 34 operations were performed on the mitral valve in the department of Thoracic and cardiovascular surgery, Korea University hospital, from Aug. 1975 to April 1979. At the first 1-year period, the closed technique was used in 12 patients. After that, open-heart surgery was used routinely; 8 patients had open mitral commissurotomy and 14 patients had valve replacement. There were 18 men and 16 women with sex ratio of 1.1: 1. The age of the patients varied widely from 18 years of the youngest to 46 years of the oldest-average aged of 32.5 years. All had symptoms and the mean duration of symptoms was 6 years and 1 month. Preoperative atrial fibrillation was 47% and embolizations were in 3 of 34 patients. The operative mortality was none for the closed and 14% for the open technique combined rate of 9 per cent which were valve thrombosis, brain embolism and left pulmonary vein rupture in deauriculization. But surviving patients undergoing open heart surgery enjoyed symptomatic benefits comparable to these of the patients of closed.

Green tea catechins(GTC) were studied for its inhibitory effect on human platelet aggregation in vitro, for its antithrombotic effect in mice in viro, and bleeding and clotting time in rats. The catechins were isolated and purified from green tea, which were composed of (-)-epigallocatechin gallate, (-)-epigallocatechin, (-)epicatechin gallate and (-)-epicatechin, GTC produced a potent inhibition of human platelet aggregation in a dose-dependent manner against the stimulants such as ADP, collagen, epinephrine and ristocetin n vitro. GTC also prevented death due to the formation of pulmonary thrombosis by platelet aggregates in mice in a dose-de-pendent manner in viro. GTC increased the bleeding time, whole blood clotting time and plasma clotting time in rats, too. These results suggest that GTC is a promising antithrombotic agent.

As apart of our continuing search for antistroke agents from the herbal medicinal resources, we examined in vitro, ex vivo and in vivo the possibility of Sunghyangjunggisan and its ingradients as a novel antithrombotic agent. In vitro ADP- and collagen-induced rat platelet aggregations were potently inhibited by Arisaematis Rhizoma, Cinnamomi Cortex and Zingiberis Rhizoma in a dose-dependent manner, but not by Sunghyangjunggisan. However, Sunghyangjunggisan significantly inhibited ex vivo rat platelet aggregation. Arisaematis Rhizoma, Atractylodis Rhizoma Alba, and Pinelliae Rhizoma also significantly inhibited ex vivo rat platelet aggregation. Sunghyangjunggisan, Alpiniae Fructus and Zingiberis Rhizoma showed significant protection from death due to pulmonary thrombosis in mice. Therefore, Sunghyangjunggisan can express the antithrombotic action, when it is orally administered.

37 years old female was admitted with chief complaints of dyspnea on exertion and hemoptysis. Past history and family history were non-contributory. Physical examination showed Grade III systolic murmur at the apex, which transmitted to the back. E. K. G. and X-ray findings were compatible with the mitral insufficiency. With small size of Beall mitral valve, mitral valve replacement was done under the cardia-pulmonary bypass using hemodilution technic. Patient was tracheotomized after operation and assisted respiration was done for four weeks. Postoperatively, all signs were fine and patient walked around the ward without any difficulty, but she was in psychotic state. On postoperative 60th day, she complained of sudden dyspnea and on chest film, tracheal stenosis was found and recannulation of the tracheal tube was made. Thereafter, she was quite fine until postoperative 110th day when she, by berself, removed the tracheal cannula and died of asphyxia. Autopsy findings of the valve showed no thrombosis, no variance of the valve, and good endothelization of the valve cuffs. Asphyxia, due to removal of the tracheal connula by herself under psychotic state, was considered to be the cause of death in this patient who had tracheal stenosis after tracheostomy.

The oral delivery of heparin is the preferred therapy in the treatment of patients with a high risk of deep vein thrombosis and pulmonary embolism. New conjugates of heparin and sodium deoxycholate were synthesized in order to enhance the heparin absorption in the GI tract. After oral administration of DOC-heparin, the concentration in anti-FXa assay was increased with increasing amount of coupled DOC. The maximum concentration of DOC-heparin VIII conjugate was $3.3{\pm}0.5\;IU/mL$ at an oral dose of 10 mg/kg, which was 3-fold higher than the baseline level. Finally, DOC coupled to heparin greatly enhanced the absorption of heparin in the GI tract, and this enhancing effect was not induced by changing the tissue structure of the GI wall.

A dead, female, 3 years old, squirrel monkey (Saimiri sciureus) was submitted and examined. Before death the monkey has showed lethargy, recumbency and inappetence since November 14, 2001 and died in November 17. Grossly much fibrin was deposited on the pleura of right lung, pericardium, and diaphragm(pleural part). And reddening of right lung was seen. Histopathologically lung showed severe fibrinous pleuritis, severe edema, thrombosis, and focal necrosis in parenchyma. Also much fibrin and mononuclear cells were deposited on the pericardium. In bacterial culture on the pleura and parenchyma of lung, and pericardium, B. bronchiseptica was isolated. Therefore we confirmed this case as the fatal case by B. bronchiseptica in squirrel monkey.

배경: 만성 폐동맥 색전증에 의한 폐동맥고혈압은 내막제거술에 의해 효과적으로 치료할 수 있는 질환으로서 본원에서의 수술 경험을 분석하여 질환에 대한 이해와 이를 토대로 향후 수술적 예후를 향상시킬 수 있는 방안에 대해 알아보고자 한다. 대상 및 방법: 1998년 1월부터 2008년 3월까지 본원에서 만성 폐동맥 색전증에 의한 폐동맥 고혈압으로 내막제거술을 받은 20명을 대상으로 후향적으로 분석하였다. 주증상은 주로 호흡곤란이었고 페동맥 색전증의 원인으로는 심부혈전증 11명(55%)이 가장 많았다. 17명(85%)의 환자에서 하대정맥 필터를 삽입하였다. 수술은 완전 순환 정지하(n=13) 또는 low flow (n=7)를 유지한 상태에서 시행하였고 수술 전 삼첨판 폐쇄부전이 grade IV/IV 이상인 환자들 중 6명(66%)에서 삼첨판륜 성형술을 함께 시행하였다. 평균 추적 관찰 기간은 $45{\pm}32$개월이었다. 결과 University of California, San Diego (UCSD)분류에 따른 폐동맥 색전증의 종류는 type I이 4명 (20%), type II, III가 각각 8명(40%)씩이었고 우심실 수축기압은 수술 전 평균 $77{\pm}29$ mmHg에서 수술 직후 $37{\pm}19$ mmHg로 감소하였으며(p<0.001) 삼첨판 폐쇄부전의 정도 및 NYHA functional class 모두 수술 후 호전을 보였다. 재관류 손상은 7예(35%)로 UCSD type I, II인 환자군에 비해 type III인 환자에서 재관류 손상의 발생률이 더 높았고(25% vs 50%, p=0.25) 중환자실 재원기간도 길었다($5{\pm}2$일 vs $9{\pm}7$일, p=0.07). 조기사망은 2명(10%)이었고 만기사망은 기저질환의 악화 1명, 폐동맥 색전증의 재발 1명, 그리고 지속된 폐동맥 고혈압 1명, 모두 3명(15%)이었다. 결론: 내막제거술은 만성 폐동맥 색전증의 효과적인 수술적 치료 방법으로서 정확한 진단을 통해 적극적으로 시행하여야 하며, 수술적 예후를 향상시킬 수 있도록 더욱 노력해야 할 것이다.
