Pulmonary arteriovenous fistula can be either congenital or acquired. The vast majority are congenital, and about 60% have been associated with hereditary hemorrhagic telangiectasia [Rendu-Osler-Weber disease . Secondary or acquired pulmonary arteriovenous fistula occurs with trauma, schistosomiasis, long-standing hepatic cirrhosis, metastatic carcinoma, and actinomycosis. Pulmonary hemorrhage secondary to acquired pulmonary arteriovenous fistula is a rare event associated with mortality. We have experienced 64 year-old female patient with the hemoptysis secondary to acquired pulmonary arteriovenous fistula due to the infection of pulmonary parasite. The chest PA and CT scan was showed calcified nodule to the distal portion of lateral segmental bronchus of RML. The bronchial angiogram was demonstrated slightly hypertrophied bronchial artery supplying RML bronchus and the presence of hypervascularization around the calcified nodule, rapid A-V shunting is noted by fluoroscopy. The patient was successfully treated by the right middle lobectomy.

In pulmonary arteriovenous fistula, there are abnormal communications between the pulmonary arteries and the pulmonary veins; the capillary networks that normally separate arteries from veins is absent. The only available treatment of this uncommon variety is an excision. We report a case of pulmonary arteriovenous fistula cured by segmentectomy with a review of literatures.

Pulmonary arteriovenous fistula is a congenital malformation of the pulmonary vasculature in which there is a persistence of one or more sizable communications that bypass the pulmonary capillary bed that thus directs unoxygenated pulmonary arterial blood directly into the pulmonary venous system. The developmental cause of pulmonary arteriovenous fistula is unknown, but it is postulated that the abnormal channels represent persistent vessels of the primitive splanchnic capillary bed that do not resorb during growth and maturation. We have experienced a case of pulmonary arteriovenous fistula. The 45 years old woman admitted to Kosin Medical College Hospital via emergency room because of massive hemoptysis, and was diagnosed pulmonary arteriovenous fistula by twice postoperative histopathologic examination. The postoperative course was uneventful and she was discharged on the 16th, second postoperative day in a healthy condition.

Pulmonary arteriovenous fistula is a congenital vascular malformation In the lung, various synonyms including Pulmonary cavernous vascular malformation, Pulmonary arteriovenous aneurysm, Cavernous hemangioma of the lung0 Pulmonary telangiectasia, Pulmonary hamartoma, etc. The pathogenesis of its symptoms is that unoxygenated, desaturated arterial blood enters into the pulmonary venous system directly. Recently we have experienced one case of the pulmonary arteriovenous fistula which was diagnosed as the pulmonary cystic lesion of the lung preoperatively in 20 years old, 61 kg, male patient. Operation was revealed well circumscribed cystic lesion filled with blood, subpleural and anterior mediobasal location, and bright red colored aspirates on two times needle aspirations. Microscopic finding shows ill circumscribed vascular lesion composed of varying sized blood vessels with irregular thickening of wall and final pathological diagnosis is Pulmonary Arteriovenous Fistula. Basal segmentectomy was done and the patient shows good postoperative course.

Pulmonary arteriovenous fistula is a rare congenital vascular malformation resulting from abnormal capillary development with incomplete formation of vascular septum normally dividing the primitive connections between the venous and arterial plexuses. Recently we have experienced a case of the bilateral pulmonary arteriovenous fistula in 7 years-old female patient. On admission, clinical manifestations were cyanosis of lips, clubbing and cyanosis of digits, and exertional dyspnea. The PO2 in arterial blood gas analysis was 43.3mmHg. In left upper and right lower lobe pulmonary arteriovenous fistulas were confirmed by bilateral pulmonary angiography. Left upper lobectomy and wedge resection of right lower lobe were performed respectively. Postoperative results were good.

Congenital coronary arteriovenous fistulas are uncommon, but well documented lesions. There are two types of congenital coronary arteriovenous fistulas according to drainage sites, the cardiac chambers or the pulmonary trunk. Especially congenital coronary arteriovenous fistula originating from the left coronary artery is rare. Two cases will be described of the two patients in whom fistulas communicating between the right coronary artery and the right atrium, left coronary artery and the main pulmonary artery each other.

Creation of an axillary arteriovenous fistula (AVF) was performed in two patients with high risks of Fontan operation after a cavopulmonary shunt. The patients complained of progressive cyanosis and decrease in exercise tolerance, and they showed pulmonary arteriovenous fistula on the pulmonary angiography. They were uneventfully transferred to the general ward on the first postoperative day and discharged 3 and 4 days after the operation respectively. There was no evidence of fistula-related volume loading and the other post-operative complications. An 8-month follow-up revealed improved symptoms such as, cyanosis and exercise intolerance, but not sufficient regression of pulmonary arteriovenous fistula on a lung perfusion scan and contrast echocardiography, which should be carefully checked hereafter.

Pulmonary arteriovenous fistula is relatively rare disease, and the most common types are congenital in origin. The clinical presentation of pulmonary arteriovenous fistula ranges from incidental finding on a chest roentgenogram to polycythemia, cyanosis, congestive heart failure, and major neurologic deficits caused by paradoxical embolism. Recently we have experienced a case of asymptomatic, well-localized pulmonary arteriovenous fistula In a 13 years-old female patient, which was successfully treated by thoracoscopic lobectomy.

Congenital coronary arteriovenous fistula is relatively uncommon and often associated with additional congenital and acquired heart disease. If coronary arteriovenous fistula is suspected, the diagnosis can be made readily by cardiac catheterization and selective coronary arteriography. Surgical treatment is very satisfactory, with a low mortality and apparent good long term result. Recently, we experienced one case of congenital coronary arteriovenous fistula which was associated with aortic stenosis and regurgitation. The tortuous fistula tract was noted between the left anterior descending coronary artery and the main pulmonary artery. Under the cardiopulmonary bypass, aortic valve replacement[Carbomedics 23mm] and suture closure of the draining orifice of coronary arteriovenous fistula in the main pulmonary artery just above the pulmonary valve were performed, Postoperative hospital course was uneventful and the patient was discharged postoperative 9th day without any problems.

Pulmonary arteriovenous fistula is unusually congenital malformation consisting of an abnormal connection between a pulmonary artery and vein. It may appear as an isolated anomaly or with hereditary hemorrhagic telangiectasis. In the classic form, symptoms and signs are caused by the abnormal right to left shunt. since severe clinical symptoms such as paradoxical embolism, infection, and spontaneous rupture with massive bleeding may occur, surgical treatment is often indicated. Recently we have experienced a surgical treatment of pulmonary arteriovenous fistula in 54 years old housewife. She was admitted in May 1986 with recurrent hemoptysis for 1 month. On admission, the PaO2 was 65.2 mmHg without specific findings. Pulmonary arteriovenous fistula was confirmed by preoperative pulmonary arteriography. A well circumscribed cystic mass was noted in visceral subpleural and inferior lingular segment of left upper lobe. Left upper lobectomy was performed with good results. Histologically angiomatous dilatation of abnormal vessels embedded in lung parenchyma was noted. Postoperative PaO2 was 90 mmHg. Postoperative results were good.
