To evaluate an occlusion technique for the internal carotid artery of horses using an intravascular, detachable, self-sealing, latex balloon distally and ligatures proximally.
Experimental study.
Six healthy adult horses.
In each horse, the left internal carotid artery was occluded by placement of an intravascular, detachable, self-sealing, latex balloon distally and two ligatures proximally. Radiographs were taken on days 2, 5, 10, and 30 after surgery to evaluate balloon inflation and position. Endoscopic examination of the left guttural pouch was performed 10 days after surgery to evaluate the integrity of the internal carotid artery and surrounding tissues. At 30 days, the left and right, common, internal, and external carotid arteries were examined grossly and then processed for histologic evaluation.
Immediate and long-term occlusion of the left internal carotid artery was achieved in all horses. The surgical procedure was technically straightforward and no intraoperative or postoperative complications were encountered. The balloons remained inflated and in their original position throughout the study. Maturing to mature, organized thrombi were present in the left internal carotid artery in all horses at 30 days. The cerebral arterial circle and common carotid artery were patent at their junctions with the internal carotid artery in all horses.
Use of an intravascular, detachable, self-sealing, latex balloon distally and ligatures proximally is an effective technique for occluding the internal carotid artery of horses.
This technique may be useful for prevention of fatal hemorrhage in horses with lesions of the internal carotid artery.
评估一种用于马颈内动脉的闭塞技术，该技术是在颈内动脉远端使用血管内可分离、自密封的乳胶球囊，近端使用结扎线。
实验性研究。
6匹健康成年马。
在每匹马中，通过在颈内动脉远端放置血管内可分离、自密封的乳胶球囊以及在近端放置两道结扎线来闭塞左颈内动脉。在术后第2天、第5天、第10天和第30天拍摄X线片，以评估球囊充气情况和位置。术后10天对左咽鼓管囊进行内镜检查，以评估颈内动脉及其周围组织的完整性。在30天时，对左右颈总动脉、颈内动脉和颈外动脉进行大体检查，然后进行组织学评估。
所有马匹均实现了左颈内动脉的即刻和长期闭塞。手术操作在技术上很简单，未遇到术中或术后并发症。在整个研究过程中，球囊一直保持充气状态并位于其原始位置。在30天时，所有马匹的左颈内动脉中均出现了成熟的、有组织的血栓。所有马匹的脑动脉环和颈总动脉在与颈内动脉的连接处均通畅。
在颈内动脉远端使用血管内可分离、自密封的乳胶球囊，近端使用结扎线是一种闭塞马颈内动脉的有效技术。
该技术可能有助于预防患有颈内动脉病变的马匹发生致命性出血。
