This study describes the arterial and venous blood vessels in the sinus tarsi of a series of nine anatomical specimens and in a traumatically amputated leg, studied by arteriography. The sinus tarsi artery was formed in all cases from anastomoses between various arteries of the lateral region of the foot. These usually included the anterior lateral malleolar, and proximal lateral tarsal arteries; in 70% there was a branch from the distal lateral tarsal artery, and in 30% a branch from the peroneal artery. In all cases, there were anastomoses within the sinus tarsi between the sinus tarsi artery and the canalis tarsi artery, derived from the posterior tibial artery. Whatever its origins, the sinus tarsi artery was the principal supplier of intrasinusal structures and of the talus. There was a large venous plexus in the sinus tarsi, which drained particularly the venous outflow from the talus and the anterior part of the capsule of the posterior talocalcaneal joint to the lateral and medial venous systems of the foot. Posttraumatic fibrotic changes in the wall and surrounding tissue of the veins, causing disturbance of venous outflow and increased intrasinusal pressure, are proposed by the authors as one possible factor in the pathogenesis of the sinus tarsi syndrome.
本研究描述了通过动脉造影术对9个解剖标本以及1条外伤性截肢腿的跗骨窦内动脉和静脉血管进行的研究。在所有病例中，跗骨窦动脉均由足部外侧区域的各条动脉之间的吻合形成。这些动脉通常包括外踝前动脉和跗骨近端外侧动脉；70%的病例中有来自跗骨远端外侧动脉的分支，30%的病例中有来自腓动脉的分支。在所有病例中，跗骨窦动脉与源自胫后动脉的跗管沟动脉在跗骨窦内存在吻合。无论其起源如何，跗骨窦动脉都是跗骨窦内结构和距骨的主要供血者。跗骨窦内有一个大的静脉丛，它特别将距骨和距下后关节囊前部的静脉血引流至足部的外侧和内侧静脉系统。作者提出，静脉壁及其周围组织的创伤后纤维化改变导致静脉流出受阻和跗骨窦内压力升高，是跗骨窦综合征发病机制中的一个可能因素。
