Abstract Congenital coronary pulmonary artery fistula (CAF) is rare, and systemic-to-pulmonary artery fistula (SPAF) is even more so. Furthermore, congenital coronary pulmonary fistula associated with congenital SPAF is extremely rare. As far as we know, CAF and SPAF connected with an aneurysm have not been described very often. We described an 83-year-old woman with an aneurysm originating from a CAF connected to an aortopulmonary artery fistula. Chest radiography revealed a shadow at the left edge of the heart line. Multi-detector-row computed tomography (MDCT) with contrast enhancement and coronary cine angiography revealed that the shadow was an aneurysm connected to a tortuous fistula at the left anterior descending coronary artery. The aneurysm was formed by congenital coronary pulmonary and aortopulmonary artery fistulae. Echocardiography revealed predominantly systolic blood flow in the fistula from the left anterior descending coronary artery (LAD). Although neither MDCT, echocardiography nor coronary angiography alone could provide a comprehensive image of the anomaly, including the hemodynamics in the fistulae and their relationship with surrounding organs and tissues, their combination could provided important facts the led to a deeper understanding of this very uncommon occurrence.

Abstract <p>The right lateral decubitus position is a risk factor for postoperative pulmonary embolism. We examined postural changes of femoral vein velocity in order to elucidate the mechanism. Thirty patients scheduled for general thoracic surgery were enrolled in this study. The common femoral veins on both sides were examined by color-duplex ultrasound for venous caliber and velocity when the patients were in the right lateral, left lateral, and supine positions. The maximum diameters of the right femoral vein in the right lateral decubitus position and the left femoral vein in the left decubitus position were significantly larger than those in the other positions. The venous velocity of the right femoral vein in the right lateral decubitus position was significantly smaller than that in the supine position, while the velocity of the left femoral vein in the left lateral decubitus position was not significantly decreased. We speculate that the decreased venous velocity of the right femoral vein in the right lateral decubitus position could result in a deep venous thromboembolism in the right leg, making this position a possible risk factor for postoperative pulmonary embolism.</p>
