Antiplatelet agent is administered to the patients who have ischemic heart disease, transient cerebral infarction, as well as hypertension, etc. Antiplatelet agent prevents thromboembolism by inhibition of platelet aggregation by various mechanism. Due to that reason, patient who administered antiplatelet agent has bleeding tendency. Surgeon does not want to make a complication by bleeding during and after operation, and want to stop taking antiplatelet agent. However, It is very dangerous for the patient to stop antiplatelet agent. Local bleeding as a complication after operation is considered minor one, whereas thromboembolism is life threatening serious complication. Most dental intervention can be performed without withdrawal of antiplatelet agent. Dental intervention should be limited area, and surgeon should do active bleeding control.

The major complications of Meckel's diverticulum (MD) are bleeding, intestinal obstruction, infection, umbilical fistula and perforation. Although the relative incidences vary between authors, bleeding is the most common complication in children. The aim of our study is to show the symptomatic guideline for the diagnosis of the bleeding MD. Eight cases with bleeding MD which were operated upon at the department of Pediatric Surgery, Yeungnam University Hospital from April 1985 to April 2001 were reviewed. Half of the patients were under 2 years of age and all patient s we re male. All patients were preoperatively diagnosed by previous history of intestinal bleeding (melena, hematochezia) and 99mTc pertechnetate MD scan. Segmental resection and end-to-end anastomosis was performed in 6 patients and diverticulectomy in 2 patients. Heterotropic gastric mucosa was found in 6 patients. Postoperative complication was not observed in any cases. In conclusion, in any male children with obscure intestinal bleeding, especially less than 2 years of age, bleeding MD must be suspected. It seems to us that 99mTc pertechnetate MD scan is a useful tool to diagnose bleeding MD.

Purpose: Traditionally, external bleeding is needed when only an arteriorrhaphy can be performed in cased where a venorrhaphy cannot be done at the initial reconstruction for a zone1 complete amputation. However, this salvage procedure has several iatrogenic complications. Therefore, we did not perform an external bleeding procedure, in cases where external bleeding was not appropriate due to the small size of the stump. Methods: From September 2006 to August 2007, 19 fingertip amputations, among 18 patients, were performed using only arteriorrhaphy without external bleeding; In total 95 fingertip amputations, with venorrhaphy or external bleeding procedures were excluded. The results were reviewed retrospectively to compare survival and complication rates. Results: The survival rate of only arteriorrhaphy without external bleeding is 84.2%. Additional operations for soft tissue problems of total or partial necrosis were performed in 5 cases. Conclusions: We found no difference in the survival and complication rates of only arteriorrhaphy without external bleeding compared to results of only arteriorrhaphy with external bleeding in other articles. Therefore, our results suggest that in some cases with a fingertip amputation, performing arteriorrhaphy only, without external bleeding, might be a better option than external bleeding due to reduced iatrogenic injuries and complications.

The incidence of Meckel's diverticulum(MD) in general population has been assessed as 2 percent. The major complications of MD are bleeding, perforation, and intestinal obstruction. In spite that the complication rate of Meckel's diverticulum is relatively high(about 4.2% during a lifetime), the preoperative diagnostic rate of complicated MD is very low. Authors investigated the clinical characteristics of complicated MD to improve the diagnostic rate. 16 patients with complicated Meckel's diverticulum who were operated upon at the Department of Pediatric Surgery, Seoul National University Children's Hospital from June 1985 to December 1993 were reviewed. Among the 16 patients with complicated MD, 12 patients(75%) were under 2 year-old and male were predominant(88%). The most common complication was bleeding patients with bleeding MD (8 cases) were diagnosed preoperatively as MD. 8 patients with other complications(perforation : 4 cases, obstruction : 4 cases) could not be suspected as complicated MD except one patient who had previous history of melena. These patients were diagnosed after exploratory laparotomy under the various impression other than MD. Among 12 patients with ulcer related complications such as bleeding and perforation, heterotopic gastric mucosa was found in 11 patients. In conclusion, in any children with unexplained acute abdomen, especially under 2 years old, complicated MD must be included in differential diagnosis. In children with obscure lower gastrointestinal bleeding, $^{99m}Tc$-pertechnetate scintigraphy is a useful diagnostic tool to rule out bleeding MD.

Background: N-Butyl Cyanoacrylate (NBCA) is a liquid embolic material that can be useful for transcatheter arterial embolization (TAE) of acute bleeding especially in patients with coagulopathy, because it does not depend on coagulation for its therapeutic effect. The aims of this study were to evaluate the clinical efficacy and safety of TAE with NBCA in acute bleeding patients. Methods: Between August 2003 and September 2004, TAE using NBCA for acute bleeding was performed in 23 patients (16 men, 7 women; mean age, 56.5years). The causes of bleeding were gastric ulcer (n=5), postoperative bleeding (n=4), post-biopsy bleeding (n=3), postpartum bleeding (n=3), duodenal ulcer (n=2), angiodysplasia (n=2), gastric lymphoma (n=1), iatrogenic injury (n=1), CMV gastritis (n=1), stab injury of the liver (n=1). TAE was performed using 1:3 mixtures of NBCA and iodized oil. The angiographic and clinical success rate, recurrent bleeding rate, procedure-related complication and clinical outcomes were evaluated. Results: The angiographic and clinical success rate was 100% and 91.3% (21/23), respectively. There was no serious ischemic complication. Recurrent bleeding occurred in 2 patients (8.7%) and they were managed with successful second TAE (n=1) and endoscopic treatment (n=1). Nine patients (39.1%) had coagulopathy at the time of TAE and clinical success rate in this group of patients was 88.9% (8/9). Conclusions: TAE with NBCA is highly effective and safe treatment modality for acute bleeding patients, especially when the patient has a coagulopathy.

Purpose: The purpose of this study was to examine the effect of position change on the level of comfort and occurrence of bleeding after transarterial chemoembolization. Methods: This study was the nonequivalent control group non-synchronized design. The experimental group was positioned in supine with 15-30 degree Semi-folwer's position for 2 hours and then changed supine position alternatively to 30 degree lateral positioning in turn per hour for 2 hours. For the control group, 6 hour supine positions without any position change were applied. Results: The level of discomfort of the control group was scored higher level than that of the experimental group. There was no significant differences in back pain and the degrees of voiding difficulty. There were no significant differences in the incidence of bleeding complication between the two groups. Conclusion: The position change in patients after transarterial chemoembolization could be applied without any severe side effects such as bleeding complication, but it was revealed to be effective in reducing the level of discomfort.

배경: 기계 심장판막 대치술 후 발생하는 혈전성 합병증을 방지하기 위해 항응고제 치료로써 와파린을 환자에게 투여한다. 이때 환자에 따른 적절한 와파린 용량을 결정하기 위한 지표로서 INR을 참고하는데 통상 대동맥판막은 $2.0{\sim}3.0$, 승모판막은 $2.5{\sim}3.5$가 참고치로서 받아들여지고 있다. 하지만 임상 경험상 대부분의 환자에서 이 수치로 유지하였을때 출혈성 합병증(비출혈, 혈뇨, 자궁출혈, 뇌출혈 등)이 빈번하게 발생하여 참고치보다 더 낮게 유지하는 경우가 많다. 이에 본원에서는 기계 심장판막 환자들을 후향적으로 조사하여 혈전성 합병증의 빈도가 낮은 적정한 INR을 알아보고자 한다. 대상 및 방법: 1984년 1월부터 2007년 2월까지 이엽성 기계 심장판막 대치술을 받고 생존한 311명의 환자를 대상으로 후향적으로 조사하였다. 대동맥판막치환 환자들(60명)은 INR $1.5{\sim}2.0$ (1군), $2.0{\sim}2.5$ (2군), 2.5 (3군) 이상의 세 군으로 나누고 승모판막치환(171명)이나 승모판막과 대동맥판막을 동시에 치환한 환자들(80명)은 INR $1.5{\sim}2.0$ (1군), $2.0{\sim}2.5$ (2군), $2.5{\sim}3.0$ (3군), 3.0 (4군) 이상의 네군으로 나누어 혈전성 합병증 발생률, 중요출혈성합병증 발생률을 조사하여 각각의 생존함수를 비교하였다. 결과: 대동맥 판막치환 환자 중 혈전성 합병증은 2명, 출혈성합병증은 4명이 발생하였고 세군의 혈전성 합병증의 생존함수의 차이는 관찰되지 않았고 출혈성 합병증의 생존곡선에서 1, 2군과 3군의 차이가 관찰되었다. 승모판막치환이나 승모판막과 대동맥판막을 동시에 치환한 환자들 중 혈전성 합병증은 13명, 출혈성 합병증은 15명이 발생하였고 네 군의 혈전성 합병증의 생존함수의 차이는 관찰되지 않았고 출혈성 합병증은 1, 2군과 3, 4군에서 차이를 보였다. 결론: 모든 판막에서 INR이 $1.5{\sim}2.5$ (1군과 2군)로 유지한 환자들이 그 이상으로 유지한 환자들보다 혈전성 합병증에서 차이를 보이지 않았고 출혈성 합병증에서 유의하게 감소하는 양상을 보여 이엽성 기계판막에서 적정한 INR은 $1.5{\sim}2.5$로 유지하는 것이 바람직하다고 판단된다.

Trauma is an important risk factor for a pulmonary thromboembolism, and anticoagulation is essential to prevent deep vein thrombosis (DVT) in patients with trauma. Low-molecular-weight heparin (LMWH) is excreted in the kidney; therefore, using LMWH in patients with renal insufficiency may increase the risk of bleeding complication. The following case describes a 55-year-old traffic accident victim who had massive bleeding and underwent a laparotomy for bleeding control. The patient had acute renal failure, and enoxaparin was administered for the prophylaxis of DVT. Although the patient suffered from serious complications such as pericardial hematoma, the patient recovered without sequellae and was discharged at day 84.

개심 수술후 위장관 계통의 합병증은 드물게 발생하지만 사망률은 매우 높은 심각한 합병증 중의 하나이 며 특히 십이지장의 합병증은 그 빈도가 매우 드문 것으로 알려져 있다. 본원에서는 개심 수술후 십이지장 출혈 1례, 십이지장 궤양 천공 2례를 치험하였다. 출혈의 경우 빈맥, 현기증, 흑색변 등의 증상이 임상적 의 심의 단서가 되었으며, 천공의 경우는 복통을 동반한 복부 팽만, 빈맥, 저혈압, 핍뇨 등이 임상적 단서가 되 었고 복막펀자술로 확진을 내릴 수 있었다. 십이지장 출혈의 경우 항제산제의 복용, 수혈 등 보존적인 방법 으로 치료되었으나 십이지장 천공의 경우에는 2례 모두에서 응급 개복수술을 필요로 하였고 1례는 병발되는 합병증으로 가퇴원하였으며, 나머지 1례에서는 장기간의 중환자실 처치를 필요로 하였다. 따라서 수술전 과 거력상 위장관 계통의 증상, 장시간의 심폐바이패스 사용등 위십이지장궤양의 위험인자가 있는 환자들에서 는 개심수술후 항궤양 약물의 예방적 사용뿐만 아니라 십이지장 합병증에 대한 임상적 의심, 조기 진단과 시의 적절한 치료가 십이지장 합병증의 이환율과 사망률을 줄이는데 필요한 것으로 생각된다.

Purpose: Congenital factor VII (FVII) deficiency is a rare bleeding disorder and surgery can cause excessive bleeding due to an extrinsic pathway problem. It can be diagnosed by increased PT and decreased FVII level in coagulation test. Symptom varies according to the level of FVII, but it is essential to prevent intraoperative excessive bleeding. Methods: In this report, we described the orthognatic surgery experience in a mandibular prognathism patient with congenital FVII deficiency, in which recombinant activated factor VII (rFVIIa) was used to manage the bleeding. Rsults: We could get a successful result without any complication and there was minimal intraoperative bleeding. Conclusion: The orthognathic surgery could therefore be safely performed in patients with congenital factor VII deficiency using rFVIIa.
