Partial Anomalous Pulmonary Venous Connection Associated with Lung Cancer in the Same Lobe: Report of a Case

Abstract

A 64-year-old man with primary lung cancer (cT1aN0M0) was diagnosed as having partial anomalous pulmonary venous connection (PAPVC) in the same lobe by preoperative chest computed tomography (CT). The anomalous vein originated from left upper lobe pulmonary vein and flowed into the left brachiocephalic vein. Although the patient was asymptomatic, cardiac catheterization revealed that pulmonary-systemic blood flow ratio (Qp/Qs ratio) was 2.0, and his pulmonary arterial pressure was marginally elevated (60/18 mmHg). We performed left upper lobectomy as the definitive treatment for both lung cancer and PAPVC. His pulmonary arterial pressure decreased after lobectomy (33/16 mmHg). He is living well without relapse of lung cancer 56 months after surgery. Although PAPVC is detectable on computed tomography, out of 7 previous reports of PAPVC associated with lung cancer, only 2 cases were diagnosed preoperatively. The presence of PAPVC should be kept in mind before major lung resections.

Partial Anomalous Pulmonary Venous Connection Coexisting with Lung Cancer: A Case Report and Review of Relevant Cases from the Literature

“…4) In the English and Japanese literature, there are 17 reported cases of PAPVC associated with lung cancer. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Including our case and these previous reports, preoperative diagnosis of PAPVC was obtained in nine (50%) cases. The other nine cases were not diagnosed as PAPVC before pulmonary resection.…”

Right S3 segmentectomy for lung cancer with partial anomalous pulmonary venous return in the right upper pulmonary vein: A case report

“…[3][4][5] In reports of 15 cases, including the present case, PAPVR was diagnosed preoperatively in seven cases, whereas it was identified intraoperatively in the other cases (Table 1). [7][8][9][10][11][12][13][14][15][16][17][18] Right upper lobectomy was the most common procedure (nine cases), and these cases had PAPVR with right V1-3 returning to the SVC or azygos vein.…”

Simultaneous three-port thoracoscopic surgery for bilateral lung cancers with a pulmonary vein anomaly: A case report

“…To the best of our knowledge, this is the first report of concomitant thoracoscopic resection of bilateral lung cancers and a PAPVC. We think this case is of remarkable pedagogic value because of our conclusion that resection of the PAPVC would have mitigated load increase in the right heart and may have alleviated the adverse effects of bilateral lung resection; additionally, the single-stage procedure may have shortened the overall duration of treatment compared with a staged procedure [ 9 , 10 ].…”
