Contrast-enhanced ultrasonography (CEUS) has been applied to evaluate parenchymal organs in human and veterinary medicine. However, to our knowledge, there is no report on the identification of active bleeding and the bleeding site in veterinary clinical patients. Herein, we describe the use of CEUS in two cases of abdominal bleeding caused by ruptured lesions with malignant abdominal tumors. One dog had a splenic hemangiosarcoma, which had metastasized to the liver; the other dog had hepatic cell carcinomas in the left hepatic lobe, which were lobectomized, and another nodule was identified in the right hepatic lobe. Immediately after the rupture of these oncogenic lesions was suspected, CEUS was performed to identify the bleeding sites. The active bleeding sites were confirmed by hyperechoic pooling signs in the arterial phase, and extravasation could be observed within the defects showing hypoechoic perfusions in the delayed phase of the CEUS. Microbubbles were also observed in the ascites; thus, CEUS could detect the presence of hemorrhage and accurately identify the bleeding site. Collectively, the study findings suggest the usefulness of CEUS in emergent situations as it enables rapid and noninvasive evaluation of bleeding points in case of active bleeding in dogs.

Bleeding after open heart surgery with cardiopulmonary bypass was a cause of concern. requiring reexploration of the chest in approximately 8 percent of patients who have had operations on the heart. From April., 1983 to October, 1991, 16 patients[2%] out of 777 patients who underwent open cardiac surgery had emergency reexploration with bleeding at the Department of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital. In 12 cases[75%], reexploration was performed for continuous bleeding and the reminder[4 cases] were performed for suspected tamponade & hypotension. There were 9 cases[56%] of congenital heart disease and 7 cases of acquired heart disease. The mean blood loss were 997$\pm$472ml /sq. M in total cases and 1442$\pm$ 647ml /sq. M in cases repair of cyanotic heart disease. The mean interval till reoperation was 16.6hr [1hr~72hr] and 41 hr[12~72hr] in tamponade cases and 8.4hr[1hr~24hr] in continuous bleeding cases. The bleeding sites were identified in 7 cases: aortotomy site in 2 cases, ventriculotomy site, SVC, thymus, pleura and sternum wiring site in each other case. But no specific sites was found in the remaining 9 cases. The 8 cases had complications but all except 1 cases with hypoxic brain damage were recovered without sequale. We conclude that emergency thoractomy after open heart surgery may be lifesaving and-/or diminishing complications with bleeding if performed promptly with excessive bleeding, tamponade and unexpected hypotension.

Gastrointestinal bleeding is a common cause of hospitalization. Jejunal diverticula is a rare disease and it is an unusual cause of obscure gastrointestinal bleeding. After exclusion of the more common bleeding sources, small bowel diverticula should be considered as a possible rare cause of gastrointestinal bleeding. Jejunal diverticular bleeding is difficult to diagnose and treat because the bleeding site cannot be identified by routine endoscopy and radiologic studies. An exploratory operation is sometimes needed to diagnose and treat obscure gastrointestinal bleeding. If the bleeding site is certain, then surgical resection of the bleeding part of the bowel is the procedure of choice. We report here on a case of jejunal diverticular bleeding that was diagnosed by and treated with surgical resection.

The four principles of treatment of odontogenic infection are as follows : (1) removal of the cause, (2) establishment of drainage, (3) institution of antibiotic therapy, and (4) provision of supportive care, including proper rest and nutrition. A separate incision is required to establish drainage, especially in the case of extensive fascial space infections. There are four principle causes for active bleeding in the immediate incision & drainage phase; (1) vascular wall alteration (infection, scurvy, chemicals), (2) disorder of platelet function, (3) thrombocytopenic purpuras, (4) disorders of coagulation (liver disease, anticoagulation drug). If the hemorrhage from incision & drainage site is aggressive, the site must be packed with proper wet gauze and wound closure & drainage dressing are applied. The specific causes of bleeding may be associated with hypoxia, changes in the pH of blood & chemical changes affecting vascular contractility and blood clotting. This is a case report of bleeding control by the circumferential suture & drainage on active bleeding incision & drainage site of temporal space abscess due to advanced odontogenic infection in a multiple medically compromised disabled patient.

서 론 : 객혈환자에서 기관지경술은 객혈의 원인질환을 진단하고 출혈위치를 진단하기 위한 중요한 검사이지만 시행하는 시기에 대해서는 논란이 있다. 객혈중이나 객혈 후 48시간내에 시행하는 조기기관지경술이 객혈 48시간후에 시행하는 후기기관지경술에 비해 출혈을 확인하는 율이 높다고 알려져 있지만 보고자에 따라 출혈부위의 진단율은 차이가 있으며 안정성에도 이견이 있다. 이에 자자들은 객혈환자에서 기관지경의 시기에 따른 안전성과 유용성을 평가하기 위해서 다음과 같은 연구를 하였다. 대상 및 방법 : 1994년 10월부터 1996년 8월까지 객혁을 주소로 삼성서울병원에 내원하여 기관지경술을 시행받은 환자를 대상으로 하였다. 기관지정 시행시기의 구분은 1995년 5월부터 1996년 8월까지 객혈을 주소로 응급실에 내원한 환자는 부득이한 사정을 제외하고 모두 48시간 이내에 기관지경을 시행하여 조기기관지경군으로, 48시간 이후에 시행한 환자는 후기기관지경군으로 삼아 출혈부위의 진단율, 객혈원인의 진단율, 기관지경과 관련된 합병증, 조기기관지경이 객혈의 치료 방침에 영향을 주었는지 여부 등을 비교하였다. 결 과 : 조기기관지경군은 71명을 대상으로 73회의 기관지경을 시행하였고 후기기관지경군은 55명의 환자를 대상으로 57회의 기관지경을 시행하였다. 객혈량과 객혈의 원인질환 따른 양군간의 유의한 차이는 없었다. 조기기관지경군의 경우 활동성 출혈이 있어서 출혈부위를 진단한 예가 28예(38.3%)로 후기기관지경군의 5예(8.7%)보다 유의하게 많았으며 (p < 0.05), 응혈을 제거하고 난 다음 출혈이 있어 출혈부위를 확인한 예는 각각 8예, 10예이었다. 전체적인 출혈부위 진단율은 조기 및 후기기관지경에서 36예(49.3%), 15예(26.3%)이었다(p>0.05). 객혈의 원인질환에 대한 진단율은 조기기관지경군에서 18예(25.3%), 후기기관지경군에서 16예(29%)로 두 군간의 유의한 차이는 없었다(p>0.05). 기관지경 결과가 치료에 영향을 준 경우는 조기기관지경군에서 수술을 시행한 6예의 환자중 4예에서 수술전 기관지경으로 출혈부위를 진단하여 수술을 시행하였고 후기기관지경군에는 수술한 4예중 1예에서만 수술전출혈부위가 진단되었다. 조기기관지경군에서 3예는 기관지경 시행후 치료방침을 조기에 결정하여 치료를 시작할 수 있었다. 기관지경과 관련된 합병증으로 조기기관지경을 시행한 2예(2.7%)에서 100cc 이상의 출혈을 보였고 이외에 조기 및 후기기관지경군에서 주요 합병증은 관찰되지 않았다. 결 론 : 객혈환자에서 객혈 후 48시간내에 시행하는 조기기관 지경술은 48시간이후에 시행하는 후기기관지경술보다 합병증의 증가없이 출혈부위를 정확하게 파악할 수 있는 시술이라 생각된다.

Background: Recently, many institutions have acquired multi-detector computed tomography (MDCT) systems. This made it easier and more convenient to use MDCT as a initial diagnostic modality for hemoptysis. The purpose of this study was to evaluate the usefulness of MDCT before bronchoscopy and/or bronchial arterial embolization (BAE) for hemoptysis. Methods: We studied a total of 125 patients with hemoptysis who underwent, between 2006 and 2008, MDCT in a routine protocol before bronchoscopy and/or BAE. One hundred two patients underwent bronchoscopy and 29 patients underwent BAE. We compared the usefulness of MDCT and bronchoscopy for detecting the bleeding site and identifying the cause. We also evaluated our ability, using MDCT, to detect instances where the bronchial artery caused hemoptysis. Results: The rate of detection of a bleeding site was 75.5% on MDCT and 50.9% on bronchoscopy. MDCT and bronchoscopy detected the bleeding site in agreement in 62.7% of patients. MDCT alone found the bleeding site in 27.5% of cases. MDCT identified the cause of hemoptysis in 77.5% and bronchoscopy in 11.8%. In 29 patients who underwent BAE, we detected a total of 37 hypertrophied bronchial arteries that were causing hemoptysis. Of 37 bronchial arteries, 23 (62.2%) were depicted on MDCT. Conclusion: MDCT is superior to bronchoscopy for detecting the bleeding site and identifying the cause of hemoptysis. MDCT can also predict the side of affected bronchial artery with depiction of hypertrophied bronchial artery and localizing the bleeding site. Doing MDCT before bronchoscopy and BAE can provide a guideline for the next step.

Background: This study was conducted to evaluate the safety and efficacy of left atrial appendage (LAA) excision using a vascular stapler. Methods: Fifty consecutive patients (mean age, 68±9 years) who underwent LAA excision using a vascular stapler during concomitant cardiac surgery were enrolled. In all patients, the excision site was evaluated using computed tomography at a median of 7 days (interquartile range, 5-13.3 days) postoperatively. The safety endpoint of this study was the occurrence of LAA excision-related events, which were defined as bleeding from the excision site that required reinforcement sutures or reoperation due to excision site bleeding. The efficacy endpoint was LAA excision failure, which was defined as a remnant LAA (a stump >1 cm in maximum length) or extravasation of radiocontrast dye. Results: LAAs were excised using 60- and 45-mm vascular staplers in 49 patients and 1 patient, respectively. Reinforcement sutures were needed in 4 patients due to staple-line bleeding and in 4 patients due to bleeding of the surrounding tissues. No patient underwent reoperation due to staple-related bleeding. A remnant LAA was observed in 2 patients, while extravasation of radiocontrast dye was not observed in any patients. Conclusion: LAA excision using a vascular stapler may be an effective technique for LAA exclusion. Delicate handling of the stapler device and LA tissue is required to prevent procedure-related complications.

Objectives: A 74-year-old male patient with unresectable advanced gastric cancer (clinical initial stage T3N+, Borrmann type III) admitted due to gastric bleeding at tumor site. On first admission day, hemoglobin level was 5.7g/dl and performance status was grade 3 according to Eastern Cooperative Oncology Group Performance Status(ECOG-PS). After performing red blood cell transfusion as an emergency treatment, hemoglobin level was increased up to 9.5g/dl. However, bleeding of oozing site was continued. For hemostasis, decoction of notoginseng radix (30g/day) was administered since day 7 after admission. The dose was elevated to 40g/day after hemoglobin level was decreased to 6.5g/dl on day 11. Since then, melena was stopped and hemoglobin level was maintained over 9.1g/dl. This case shows the hemostasis effect of decoction of notoginseng radix on gastric bleeding in unresectable advanced gastric cancer.

Gastrointestinal (GI) bleeding is one of the most common conditions among patients visiting emergency departments in Korea. GI bleeding is divided into upper and lower GI bleeding, according to the bleeding site. GI bleeding is also divided into overt and occult GI bleeding based on bleeding characteristics. In addition, obscure GI bleeding refers to recurrent or persistent GI bleeding from a source that cannot be identified after esophagogastroduodenoscopy or colonoscopy. The small intestine is the largest part of the alimentary tract. It extends from the pylorus to the cecum. The small intestine is difficult to access owing to its long length. Moreover, it is not fixed to the abdominal cavity. When hemorrhage occurs in the small intestine, the source cannot be found in many cases because of the characteristics of the small intestine. In practice, small-intestinal bleeding accounts for most of the obscure GI bleeding. Therefore, in this review, we introduce and describe systemic approaches and examination methods, including video capsule endoscopy and balloon enteroscopy, that can be performed in patients with suspected small bowel bleeding in clinical practice.
