A persistent sciatic artery (PSA) is very rare congenital vascular anomaly which is present in 0.025% to 0.04% of the population by an angiographic study. A PSA is usually combined with aneurismal disease or thromboembolic events because of its arteriosclerosis and vessel wall degeneration. The treatments of symptomatic PSA are comprised of exclusion of PSA from circulation and bypass surgery for the lower limb. However, surgical treatment should be tailored to its anatomy and presentation. We report a successful treatment of PSA with distal thromboembolism by thromboembolectomy without bypass surgery.

Background: Acute pulmonary thromboembolism is fatal because of abruptly occurring hypoxemia and right ventricular failure. There are several treatment modalities, including anticoagulation, thrombolytics, ECMO (extracorporeal membrane oxygenator), and thromboembolectomy, for managing acute pulmonary thromboembolism. Materials and Methods: Medical records from January 1999 to December 2004 at our institution were retrospectively reviewed for pulmonary thromboembolectomy. There were 7 patients (4 men and 3 women), who underwent a total of 8 operations because one patient had post-operative recurrent emboli and underwent reoperation. Surgery was indicated for mild hypoxemia and performed with CPB (cardiopulmonary bypass) in a beating heart state. Results: The patients had several symptoms, such as dyspnea, chest discomfort, and palpitation. Four patients had deep vein thromboembolisms and 3 had psychotic problems, specifically schizophrenia. Post-operative complications included hemothorax, pleural effusion, and pericardial effusion. There were two hospital deaths, one each by brain death and right heart failure. Conclusion: Emergency operation should be performed when medical treatments are no longer effective.

Pulmonary thromboembolism originated most commonly from the venous thrombus, especially deep vein thrombus in the leg, which migrated to and occluded the pulmonary vasculatures. The failure of clot lysis and repeated embolic episodes resulted in the hemodynamic compromise -that is- in the increasing in the pulmonary vascular resistance, which would cause the right ventricle failure[Car Pulmonale]. Under the cardiopulmonary bypass, 20 year old male patient was treated successfully by thromboembolectomy of pulmonary thromboembolism with pulmonary hypertension, which originated from the deep vein thrombus in the leg. The results of radiologic studies and clinical evaluations were excellent in that the postoperative lung perfusion scan showed the newly increased perfusion of post-embolectomy territories and in the arterial blood gas finding of 76 from 66[mmHg] in PaO2. The patient was uneventful and discharged on postop. $ 14 days with anticoagulant continued.

We present one case of 26-year-old male having saddle block combined with mitral valvular disease [NYHA Class IV] with auricular fibrillation. The most common cause of emboli is atrial fibrillation. The clinical manifestations of saddle emboli are relatively slow due to development of collateral circulation and large size of lumen of the aorta. The 5month duration of saddle emboli in this case led to severe atrophic changes, coldness, peripheral cyanosis on the both lower extremities, and flexion deformity on the knee and ankle joint of the left lower extremity. We planned staged operation for the saddle block and for mitral stenoinsufficiency and tricuspid insufficiency, because of poor general condition of the patient. The thromboembolectomy of aortic bifurcation was performed through the transabdominal approach without trial of Fogarthy catheter embolectomy, because of expectation of the secondary inflammatory changes of the vessel wall and thrombi which was 3 cm X 1 cm X 0.5 cm in size with irregular surfaced solid in consistency. 1 month later, after thromboembolectomy, mitral valve replacement and tricuspid annuloplasty were performed, with successful early operative result. During operation organized thrombi [1 cm X 0.5 cm] in the left auricle was removed. We wonder if simple management using Fogarthy catheter might be possible to remove the thromboemboli instead of thromboembolectomy by aortotomy in this case.

배경: Fogarty 카테터는 원위부 동맥 색전을 제거하기 위하여 고안되었으며 1960년대 이래로 급성혈전색전의 치료에 획기적인 치료법이 되었다. 그러나 지난 30년동안 동맥폐쇄의 주원인이 심장에서 비롯하는 색전으로부터 죽상동맥경화증으로 변화하였으며 이런 맥락에서 단순 Fogarty 혈전색전제거술이 여전히 효과가 있는지 의문점이 생긴다. 대상 및 방법: 1990년 3월부터 2008년 8월까지 본원에서 Fogarty 혈전제거술을 시행한 156명을 대상으로 하였다. 환자를 혈전제거술만 시행한 79명(제 1 군)과 혈관우회수술을 같이 시행한 77명(제 2 군)으로 나누어 증상의 기간, 혈전의 원인, 응급실 내원 여부, 한방치료 및 오진경험, 동반질환, 주발생부위, 사망원인 등을 후향적으로 T 검증, 교차분석, 카이제곱 및 Kaplan-Meier을 이용하여 비교분석 비교하였다. 결과: 두군 모두 환자의 나이는 평균 64$\pm$10세로 비슷하였다. 제1군과 2군의 다리 통증 기간은 평균 12$\pm$4일 vs 71$\pm$14일(p=0.001), 응급실 내원한 경우는 50명(63%) vs 18명(23%) (p=0.005), 디스크로 오인하여 치료를 받거나 침을 맞은 경우가 20명(25%) vs 30명(39%), 내원전 항응고제 치료 받은 경우는 22명(28%) vs 11명(14%), 혈전원인은 심장질환 24명(30%) vs 6명(8%) (p=0.001), 동맥경화증 46예(58%) vs 67명(87%) (p=0.001), 외상 9명(11%) vs 6명(8%)이었다. 동반질환으로는 뇌졸증, 고혈압 당뇨가 주를 이루었으며(22$\sim$37%), 막힌 부위는 대부분 장골 및 대퇴동맥이었다 우회수술은 58명(75%)에서 대퇴-대퇴 및 대퇴-슬와동맥간 우회수술을 시행했다. 내막절제술은 각각 7명(9%) vs 18명(23%)에서 동반시술이 이루어졌다(p=0.012). 수술의 성공율은 27명(34%) vs 40명(52%) (p=0.019), 다시 막힌 경우는 37명(47%) vs 20명(26%) (p=0.000), 하지절단 4명(5%) vs 12명(16%) (p=0.012), 사망 10명(13%) vs 3명(4%) (p=0.044)으로 의의있는 차이를 보였다. 결론: 최근 급성동맥폐쇄증의 원인이 류마티스 심장질환에서 동맥경화성 질환으로 변화함으로서 단순한 Fogarty 혈전색전 제거술의 효과가 줄어들고 있어 이러한 단순 시술 대신에 부가적인 우회수술법이 고려되어야 할 것이다.

Systemic emboli occur in approximately one-third of patients with cardiac myxoma. Embolization is common because of the friability of the tumor and intracardiac location. Embolic episodes in young patients with normal sinus rhythm should arouse suspicions of cardiac myxoma in the absence of active endocarditis. We present one case of 17 years old girl having saddle embolism combined with left atrial myxoma. We planned staged operation. First, the emergency thromboembolectomy of aortic bifurcation was performed through bilateral transfemoral approach with use of Forgaty catheter. One week later, the extirpation of myxoma was successfully done with ECC.

만성 색전성 폐동맥 고혈압의 치료는 폐이식을 제외하면 폐동맥 색전제거술이 유일하지만, 수술 사망률이 6.6∼23%로 높게 보고되고 있다. 수술을 시행하기 전에 수술의 적응이 되는 환자인지를 판단하고, 수술을 시행할 때 전체 폐동맥 분지에 대해 충분히 색전을 제거하는 것이 수술의 성공적인 시행을 결정하는 가장 중요한 요인이다. 본원에서는 만성 폐동맥 색전증의 수술적 치료시 완전순환정지를 적용하여 좋은 수술 시야를 확보함으로써 각 구역 폐동맥수준까지 혈전을 제거하는 것이 유용한 방법임을 확인할 수 있었고, 술 후 합병증이 없이 안전하게 시행할 수 있었음을 문헌고찰과 함께 보고하는 바이다.

in general rapid and complete resolution of pulmonary emboli, even massive, is the natural history. However, rarely, the emboli do not resolve but rather became fibrotic organization and densely adherent to the arterial wall, therefore, may lead to significant clinical disability. In patients with chronic pulmonary embolism, medical management usually has little effect and only surgical treatment can offer improvement. The case was 30-year-old man who had admission to the Hanyang University Hospital due to fall-down from 11th floor 407 days before operation and then transferred to our department for surgical management under the diagnosis of chronic pulmonary embolism, Pulmonary angiogram demonstrated multifocal thromboembolism with infarction and lung scans showed no improvement in spite of anticoagulant and thrombolytic therapy. At median sternotomy for pulmonary artery thromboembolectomy, the well organized and multiple septic emboli could be removed by gallstone forceps. But reoperation of left upper lobectomy was performed because of the repeated hemoptysis and suspicious pulmonary arterio-bronchial fistula 19 days postoperatively. Despite of ventilatory support and drug treatment, the patient died due to right heart failure associated with cor pulmonale 27 days after first operation. Discussion of the operative and perioperative problems are offered.

Abdominal aortic occlusion (AAO) caused by detachment of cardiac myxoma (CM) is a very rare complication in patients with CM. Although the nature of CMs has been well established, detachment of CM may cause unexpected serious complications such as vicious embolic events. Actually, in several cases of AAO caused by detachment of CM, it has been reported that CM fragments easily migrated to the brain, heart, and lungs, and caused lifelong neurological complications despite appropriate surgical therapy. Herein, we report a case of a patient with AAO caused by detachment of CM who underwent CM excision and abdominal aortic thromboembolectomy. Additionally, we have presented the preoperative and postoperative images using 64-multidetector computed tomography.

A 39-year-old man presented with cough, chest discomfort, and weight loss. On the basis of the patient history and laboratory findings, he was diagnosed with the hypereosinophilic syndrome. Transthoracic echocardiography revealed a large thrombus in the left ventricle. Medical treatment with anticoagulation and immunosuppression was commenced immediately. Fourteen days after the initial diagnosis, the patient presented with acute pain in his right leg. Computed tomographic angiogram showed embolic occlusion of the infrarenal abdominal aorta and bilateral iliac (including common, external, and internal iliac) arteries. Emergent thromboembolectomy and left ventricular thrombectomy were performed. The postoperative course was uneventful, and the patient has undergone follow-up for 2 months without any evidence of recurrence of thromboembolism.
