A 4-month-old, female Maltese dog was referred with continuous heart murmur. Patent ductus arteriosus was diagnosed via radiography and echocardiography. The patient was untreated because of client's refusal. After 13 months, the dog was referred again with seizure and salivation. Laboratory examination revealed increased liver enzymes, hyperammonemia and decreased total cholesterol and total protein. Microhepatica was identified on abdominal radiography. CT angiography showed a shunt vessel that originated from the portal trunk to the prehepatic caudal vena cava and patent ductus arteriosus connecting proximal descending aorta with the main pulmonary artery. No portal vasculature toward liver is observed after shunt vessel. The patient was diagnosed as concurrent patent ductus arteriosus and congenital extrahepatic portosystemic shunt with suspected portal vein aplasia. In human, cardiac malformations are frequently observed in patients with congenital extrahepatic portosystemic shunt with portal vein aplasia. This report described concurrent patent ductus arteriosus and congenital extrahepatic portosystemic shunt with suspected portal vein aplasia in a dog.

Pulmonary embolism is one of the moot common acute pulmonary disease in the adult general hospital population However, the disease is still frequently unsuspected and underdiagnosed due to the nonspecificity of both clinical findings and laboratory tests. The chest radiography in a patient suspected acute pulmonary embolism do not provide adequate information to establish or exclude the diagnosis of pulmonary embolism. Even in the case of infarction, there is no pathognomonic clues on the chest film. Rarely infarction presents unusual roentgenologic manifestation such as lobar consolidation, coin lesion, multinodular opacity, or massive pleural effusion Especially, lobar consolidation in pulmonary embolism might mislead into the diagnosis of pneumonia. We experienced a case of pulmonary embolism presenting lobar consolidation in a 62 years old woman, originated from deep vein thrombosis. She took a compression stocking and underwent anticoagulant therapy with excellent outcome.

Background: Deep vein thrombosis (DVT) and pulmonary embolism (PE) are conditions with significant morbidity and mortality. Proximal DVT has a significant association with PE and possible fatal outcomes. Traditionally, PE is subdivided into symptomatic PE and asymptomatic PE, which have different treatments, preventions and prognoses. The growing utilization of computed tomography pulmonary angiography has led to increased detection of PE in DVT patients. This study examined the clinical characteristics and compared symptomatic PE and asymptomatic PE following proximal DVT. Methods: The medical records of 258 DVT inpatients from July, 2012 to June, 2015 were reviewed retrospectively. After excluding the patients who did not performed PE evaluation and were not diagnosed with PE, 95 patients diagnosed with PE following proximal DVT were enrolled in this study. They were divided into the symptomatic PE group and asymptomatic PE group. Results: The body weight, body mass index, thrombus size, thrombus length and location were similar in the two groups. The symptomatic PE following proximal DVT group showed an older age, higher incidence of emergency department access (85.0% vs. 38.7%, p<0.001) and preceding infection (25.0% vs. 1.3%, p<0.001) as well as a higher incidence of immobilization (45.0% vs 13.3%, p=0.016). In the multivariate logistic regression study, preceding infection and emergency department access showed significant association with symptomatic PE. Conclusion: In proximal DVT inpatients, symptomatic PE was associated with emergency department access and preceding infection. The possibility of a symptomatic PE event should be considered in proximal DVT patients, especially those who were admitted through the emergency department and had preceding infection.

An azygos vein aneurysm is a very rare cause of a posterior mediastinal mass. Once the diagnosis has been confirmed, no treatment is usually required. However, the aneurysm can thrombose, and this may lead pulmonary thromboembolism, or the aneurysm may rupture. In these instances, the excision of the mass is recommended. Video-assisted thoracic surgery techniques have considerably improved. If it is necessary to remove the aneurysm, video-assisted thoracic surgery may be a good option for surgical treatment. We report a case of an aneurysm of the azygos arch that was successfully resected by video-assisted thoracic surgery.

From July 1988 to January 1991 six patients, aged 29 to 70 years underwent transfemoral thrombectomy for the treatment of deep vein thrombosis. Preoperative venograms showed thrombi in the following locations: calf veins[five], superficial femoral or popliteal veins [four], common femoral veins[three], and iliac veins[three], Durations of symptoms before admission were from 1 day to 20days. Operations were performed under local anesthesia and all the patients were requested for doing Valsalva maneuver during thrombectomies. All patients were received heparin pre-and postoperatively, which was switched to Coumadin for preventing of rethrombosis. One patient was transferred to other hospital 4 months after operation due to regional reason, and the remained five patients were evaluated with a mean follow-up time of 20 months. There was no evidence of postoperative pulmonary embolism. Three of five patients were clinically asymptomatic. One complained of the heaviness of involved leg in the evening, and the other had discomfort on walking Even though our cases were a few in number, we concluded that thrombectomy is a valuable treatment modality of deep vein thrombosis.

Lower extremity deep vein thrombosis (DVT) is a serious medical condition that can result in local pain and gait disturbance. DVT progression can also lead to death or major disability as a result of pulmonary embolism, postthrombotic syndrome, or limb amputation. However, early thrombus removal can rapidly relieve symptoms and prevent disease progression. Various endovascular procedures have been developed in the recent years to treat DVT, and endovascular treatment has been established as one of the major therapeutic methods to treat lower extremity DVT. However, the treatment of lower extremity DVT varies according to the disease duration, location of affected vessels, and the presence of symptoms. This article reviews and discusses effective endovascular treatment methods for lower extremity DVT.

Protein S deficiency is one of the several risk factors for thrombophilia and can cause blood clotting disorders such as deep vein thrombosis and pulmonary embolism. A 54-year-old man was admitted with the complaint of dyspnea and was diagnosed with pulmonary embolism. The patient had very low level of free protein S, total protein S antigen, and protein S activity (type I protein S deficiency). In history taking, we found that his mother, 78 year old, had a history of same disease 10 years ago, and confirmed the pronounced low level of protein S. The patient's son also had very low level of protein S, however there had not been any history of pulmonary embolism yet. This case study suggests that asymptomatic persons with a family history of protein S deficiency and pulmonary embolism should be checked regularly for early detection of the disease, as protein S deficiency can be suspected.

Pulmonary arteriovenous fistula is a congenital malformation resulting from errant capillary development, with incomplete formation or disintegration of the vascular septa that normally divide the primitive connections between the venous and arterial plexuses. It generally occurs as part of the disorder known as hereditary hemorrhagic telangiectasia [Rendu-Osler-Weber disease]. The hereditary lesion is transmitted as a simple non-sex-linked dominant trait. It may be single or multiple, too small to see on plain chest films or large and easily recognized. One third of the lesions are multiple on plain chest film. The pathogenesis of its symptoms is that unoxygenated, desaturated arterial blood enters into the pulmonary venous system, directly. Recently we have experienced a case of the pulmonary arteriovenous fistula in 26 years old male soldier, which was confirmed by pulmonary angiography preoperatively. 2 thumb-tip sized, well circumscribed cystic masses filled with bright red colored blood were seen in subpleural and anterolateral portion of the right upper lobe. Right upper Iobectomy was performed due to close approximation of the fistula with pulmonary vein. Microscopically, it shows angiomatous dilatation of the abnormal vessels embedding in the parenchyma. Postoperative physiologic studies show nearly normal arterial oxygen saturation, hemoglobin and RBC count. There was good, uneventful postoperative course.

목 적 : 총폐정맥 환류이상은 드문 선천성 심장질환이나, 진단 즉시 완전 교정 수술이 필요한 질환이며 폐정맥 협착 동반 유무에 따라 수술 사망률과 예후가 다르게 보고되고 있다. 이번 연구는 총폐정맥 환류이상 환아를 조사하여 이들의 임상적 특성과 수술 후 경과를 살펴보고자 시행하였다. 방 법 : 1994년 1월부터 2008년 2월까지 14년간 경북대학교병원에서 총폐정맥 환류이상으로 진단된 환아 27명의 의무 기록 정보를 후향적으로 분석 하였다. 결 과 : 총폐정맥 환류이상 환아 27명은 남아 17명, 여아 10명이었고, 진단 시 나이는 평균 $28.1{\pm}33.4$일(1-126일), 평균 체중은 $3.6{\pm}0.9$ kg (1.9-6.3 kg)였다. 병원을 방문한 주 증상으로 빈호흡, 저산소증 등의 호흡기 증상이 7명, 수유 시 청색증이나 전신 청색증이 13명, 심잡음이 7명이었다. 13명(48.1%)에서 심부전 소견을 보였다. 심초음파 검사로 진단된 해부학적 형태로 심상부형이 15명(55.6%), 심형이 6명(22.2%), 심하부형이 5명(18.5%)이고 혼합형은 1명(3.7%)있었다. 수술 전 폐정맥 협착이 동반된 경우는 7명으로 심상부형에서 5명, 심형과 심하부형에서 각각 1명이었다. 본원에서 수술 받은 환아는 총 24명으로 수술 중 경식도 초음파 검사는 14명(58.3%)에서 시행하였다. 수술 중 경식도 초음파 검사를 사용한 경우의 사망률은 0%이고 사용하지 않은 경우의 사망률 40%로 유의한 차이(P<0.05)를 보였다. 수술 사망은 4명(16.7%)으로, 수술하지 않고 사망한 환아 2명을 포함하여 전체 사망률은 22.2%였다. 그러나 수술 시기를 2000년을 기준으로 구분하여 살펴보면, 사망한 4명 모두 2000년 이전이었으며(사망률 50%, 4/8명), 2000년 이후에는 수술 후 사망이 한 명도 없었다(사망률 0%, 0/18명). 수술 후 폐정맥의 협착은 심초음파 검사로 진단하여 5명에서 발생하였다. 5명중 3명은 수술 부위의 협착이고 나머지 2명은 폐정맥 자체의 협착이었다. 수술 부위의 협착을 보인 3명은 재수술을 시행하였고(평균 기간 : 24일) 재수술 후 사망률은 0%이며, 현재 모두 약물치료는 시행하지 않으며 특별한 증상도 보이지 않으나 3명 모두 정기적으로 시행한 심초음파에서 후기 재 협착 소견을 보였다. 이들이 수술 부위의 후기 재 협착이 진단되기까지의 평균 기간은 31.3개월(17-54개월)이었다. 폐정맥 자체의 협착을 보인 환아는 2명으로, 교정 수술 후 심초음파 검사로 진단되기까지의 기간은 각각 3개월과 84개월이었다. 추적 관찰되었던 환아 20명에서 평균 관찰 기간은 $24.2{\pm}24.9$개월(2-80개월)이었다. 결 론 : 수술 후 폐정맥 협착 및 수술 부위의 재 협착이 발생할 수 있으므로 수술 중 경식도 초음파 검사의 적극적 이용과 수술 후 정기적이고 지속적인 관리가 필요할 것으로 생각된다.
