绵羊支气管动脉的解剖最近已有报道。然而，支气管静脉的行程尚未得到很好的确定。有人认为支气管静脉是组胺输注后液体渗漏的主要部位，并推测支气管循环可能在液体重吸收中起作用。本文对18只绵羊的支气管循环进行了解剖学研究，重点是支气管静脉回流和支气管与肺动脉的交通。麻醉后，将动物肝素化并放血。将伊文思蓝染料注入6只绵羊的支气管动脉，研究了支气管循环的大体和亚大体解剖。在另外6只绵羊的支气管动脉、肺动脉和气管支气管树中充满了不同颜色的巴特森溶液。在解剖显微镜下进行亚大体解剖学研究，并采集样品进行扫描电子显微镜检查。在6只单独的绵羊中，我们通过将染料直接注入静脉来研究近端静脉的解剖结构，发现肺外支气管血液通过单一血管流入左奇静脉。肺内支气管被密集的支气管微血管丛包围，微血管丛在毛细血管前水平排入肺血管。
The anatomy of the bronchial artery in sheep has recently been described. However, the course of the bronchial veins has not been well established. It has been suggested that the bronchial veins are the major site of fluid leakage following histamine infusion, and it has been postulated that the bronchial circulation may play a role in fluid reabsorption. We studied the anatomy of the bronchial circulation in 18 sheep with emphasis on bronchial venous drainage and bronchopulmonary communications. Following anesthesia animals were heparinized and exsanguinated. Evans blue dye was infused into the bronchial artery in six sheep and the gross and subgross anatomy of the bronchial circulation studied. In six other sheep the bronchial artery, pulmonary artery, and tracheobronchial tree were filled with Batson's solution of varying colors. The subgross anatomy was studied under a dissecting microscope, and samples were taken for scanning electron microscopy. In six separate sheep we studied the anatomy of the proximal vein by infusing dye directly into the vein and found that the extrapulmonary bronchial blood drained into the left azygos vein via a single vessel. Intrapulmonary bronchi are surrounded by a dense bronchial microvascular plexus which drains into the pulmonary vessels at the precapillary level.
