Radiofrequency ablation is an effective treatment for atrial fibrillation. Pulmonary vein stenosis/occlusion is one of its rare complications. Herein, the case of a 50-year-old man with hemoptysis and migratory pulmonary infiltrations after transcatheter radiofrequency ablation for atrial fibrillation is presented. Initially, pneumonia, interstitial pulmonary disease, or lung cancer was suspected, but wedge resection revealed hemorrhagic infiltrations. Chest computed tomography pulmonary angiography detected no left superior pulmonary vein due to its total occlusion, and left upper lobectomy was performed. Post-ablation pulmonary vein occlusion must be strongly suspected in cases of migratory pulmonary infiltrations and/or hemoptysis.

선천성 폐정맥 협착증은 매우 드문 기형으로 진행성 폐동맥 고혈압 및 조기 심부전으로 사망률이 높아 적극적인 내외과적 치료가 요구된다 수술적 치료법으로는 품선 확장술, 스텐트 삽입술, 전폐절제술, 폐이식술, 패취 봉합술, 그리고 무봉합 교정술 등이 있다. 본원에서는 정상적인 해부학적 연결을 가진 폐정맥 협착증에서 무봉합 교정술 및 수술 후 Sildenafil, Iloprost 그리고 NO gas등의 폐혈관 확장제를 사용하여 성공적으로 치료한 1예를 경험하여 이를 보고하고자 한다.

We have performed four left lung reimplantation and right pulmonary artery ligation in dogs for six months from March 1989 to September 1989 at the Thoracic & Cardiovascular Surgery department, Yonsei University, College of Medicine, Seoul, Korea. Excised left lungs were perfused with 200cc of 4oC cold saline at a pressure of 60cmH2O through left pulmonary artery & preserved in 4 oC cold saline for about 20 mins. Left lung reimplantation were proceeded with inferior pulmonary vein, superior pulmonary vein, left pulmonary artery and left main bronchus in order. The main pulmonary artery pr. were 39/21[31], 22/12[15], 25/9[15] and 54/17[37] mmHg each after right pulmonary artery ligation on left reimplanted dogs, Right pul a. ligations were performed 9 days, 12 days, 16 days and 19 days after left lung reimplantation. Two dogs died at 10 days 21 days, after right pul. a. ligations in left reimplanted dogs. The remaining two dogs were sacrificed at 18 days, 21 days after right pul. a. ligation in left reimplanted dogs. Autopsy findings showed narrowing of left superior pul. vein anastomotic site in two narrowing of left pulmonary artery anastomotic site in one narrowing of left sup. pul vein & pneumonia of left lung in one. In the lung transplantation, it was thought to be important that the anastomosis of pulmonary artery and especially pulmonary vein be done with particular precaution for early and late stenosis.

Pulmonary artery sarcoma (PAS) is a rare and fatal disease that often mimics chronic thromboembolic pulmonary hypertension (CTEPH); therefore, diagnosis of PAS is often delayed. Herein, a healthy 74-year-old man was presented with a 4-month history of dyspnea. Chest computed tomography showed wall thickening and stenosis in the main pulmonary artery as well as in both proximal pulmonary arteries. In order to differentiate between unusual CTEPH, vasculitis, and PAS, we performed right heart catheterization and pulmonary angiography. The mean pulmonary arterial pressure was 21 mmHg, and there was severe pulmonary artery stenosis. Thrombi on the pulmonary arterial wall lesions were observed in intravascular ultrasound and optical coherence tomography. Furthermore, the patient had a history of deep vein thrombosis. Therefore, we diagnosed unusual CTEPH. After 6 months of rivaroxaban anticoagulation therapy, a chest X-ray revealed a left lower lobe lung mass, and a positron emission tomography later showed hypermetabolic lesions in the main pulmonary artery wall, in both pulmonary arteries walls, in the lung parenchyma, and in the bones. A biopsy of the right proximal humerus lesion revealed undifferentiated intimal sarcoma. Pulmonary sarcoma is rare, but should be considered when differentially diagnosing main pulmonary artery wall thickening and stenosis. A positron emission tomography may aid in this diagnosis.

Pulmonary arteriovenous malformation (AVM) is a congenital vascular disease in which interventional radiologists can play both diagnostic and therapeutic roles in patient management. The diagnosis of pulmonary AVM is simple and can usually be made based on CT images. Endovascular treatment, that is, selective embolization of the pulmonary artery feeding the nidus of the pulmonary AVM, and/or selectively either the nidus or draining vein, has become a first-line treatment with advances in interventional devices. However, some vascular diseases can simulate pulmonary AVMs on CT and pulmonary angiography. This subset can confuse interventional radiologists and referring physicians. Vascular mimickers of pulmonary AVM have not been widely known and described in detail in the literature, although some of these require surgical correction, while others require regular follow-up. This article reviews the clinical and radiologic features of pulmonary AVMs and their mimickers.

Congenital coronary arterial fistulae are the most prevalent hemodynamically significant congenital coronary artery malformations. Definition of congenital coronary arterial fistula is a direct communication between a coronary artery and the lumen of one of the four cardiac chambers or coronary sinus or SVC, pulmonary artery or pulmonary vein close to the heart. It is often associated with additional congenital or acquired heart disease. A 49 year old male patient was admitted with the chief complaints of anginal pain and exertional dyspnea for 9 months. He was diagnosed as the right coronary arterial fistula combined with right coronary arteriosclerotic stenosis and old inferior myocardial infarction by cardiac evaluation. The right coronary arterial fistula was communicated between the just distal portion of acute marginal branch and coronary sinus. The operative procedure was as followings; after suture ligation of fistula opening in the coronary sinus under beating heart, coronary arterial bypass grafting with saphenous vein was performed at the just proximal portion of the posterior descending branch under cardiopulmonary bypass. The postoperative course was uneventful and he was discharged without anginal pain at the 8th postoperative day.

Two patients with uncorrectable cyanotic cardiac anomalies underwent total cavopulmonary shunt[modified Fontan operation]. Case I was a 14 years old male with dyspnea and cyanosis after birth. Aortogram showed TGA combined with overriding of aorta, pulmonary stenosis, complete atrioventricular septal defect, interruption of inferior vena cava, and situs inversus totalis. We had performed total cavopulmonary shunt using with 16 mm Gortex Graft in single atrium to bypass the hepatic vein to pulmonary artery. Postoperatively, patient sustained low PaCO2 and low cardiac output and then expired at 19th postoperative day. The cause of death of the patient would be low cardiac output. Case II was a 6 years old female with dyspnea and cyanosis after birth. Aortogram showed tricuspid atresia[Type IIb], transposition of great arteries, atrial septal defect, ventricular septal defect and pulmonary stenosis, We had performed total cavo-pulmonary shunt using intraatrial baffle[tunnel] with Goretex patch. The postoperative course of this patient was good without event.

환아는 생후 18개월 된 여아로 반복적인 위급한 과량의 객혈을 주소로 입원하였다. 과거력상 생후 6개월에 중증의 심비대 소견을 보이는 심방중격결손증을 진단받았으며 폐정맥 협착이 심비대에 의한 압박으로 생긴 이차적인 병변일 것이라 추정하여 심방중격결손폐쇄술만 시행하였다. 술 후 환아는 심비대와 폐정맥 협착이 완화된 소견을 보였다. 그러나 추적 관찰 중 환아는 반복적인 다량의 객혈로 다시 입원하였고 전산화단충촬영 소견 상 폐정맥 협착이 다시 심해진 것으로 판독되었으며 기관지 주변에 성상을 알 수 없는 연조직 종괴들이 좌측 기관지를 압박하고 있었다. 정확한 위치를 알 수 없는 반복적인 객혈로 인해 시험적 개흉술이 불가피하였고, 수술 소견상 좌폐정맥은 하나였으며 외견상 협착의 소견을 보였다. 좌측 기관지 주변에는 다발성 임파절 비대가 기관지를 압박하고 있었다. 또한 수술 중 다량의 객혈이 발생하여 전폐절제술을 시행할 수밖에 없었다. 술 후 병리 소견은 폐정맥 협착과 일치하였다. 환아는 2일간의 중환자실 관리 후 6일째 합병증 없이 퇴원하였다. 2개월간 추적 관찰되었으며 증상 없이 양호한 경과를 보이고 있다. 그러나 향후 지속적인 추적 관찰이 필요할 것으로 생각한다.

This is a report of a migrated polyethylene catheter from the arm vein cutdown site into the heart. The patient was a 48 years old male who was operated on for mitral stenosis complicated with pulmonary hypertension. On the 8th postoperative day after open mitral commissurotomy, polyethylene catheter embolization occurred. The catheter was removed successfully with an incision on the proximal basilic vein. The patient recovered uneventfully and discharged without complications.

기관지 정맥류는 기관지 정맥압이 상승하는 승모판 협착증이나 폐정맥 폐쇄증에서 이차적으로 발생할 수 있다. 기관지 정맥류는 주로 좌측 주기관지에서 관찰되며, 드물지만 기관지 정맥류의 파열로 대량 객혈이 가능하고 사망할 수도 있다. 저자들은 중증 승모판 협착증 환자에서 동반된 기관지 정맥류를 기관지내시경에서 우연히 관찰하였고 승모판치환술 후 기관지 정맥류가 호전되어 이를 문헌고찰과 함께 보고하는 바이다.
