Balloon-tipped catheters were used to occlude the external carotid artery and its branches in nine horses with hemorrhage caused by guttural pouch mycosis. The internal carotid artery on the affected side was occluded simultaneously in four horses and had been occluded previously in two others. In three horses, a single balloon-tipped catheter was inserted in the external carotid artery beneath the floor of the guttural pouch and its tip was advanced blindly into distal branches. In one horse, the superficial temporal artery was occluded briefly during surgery by a balloon-tipped catheter so a catheter inserted into the external carotid artery could be diverted into the maxillary artery. In the other five horses, the external carotid artery was occluded proximally and the maxillary artery was occluded immediately caudal to the alar canal by a balloon-tipped catheter inserted into the major palatine artery. Serious postoperative hemorrhage did not occur in eight horses, but one horse that had a single balloon-tipped catheter inserted into the external carotid artery had profuse hemorrhage 11 days after surgery and was euthanatized. One horse was euthanatized because of persistent dysphagia. The only complication related to use of balloon catheters was a mild incisional infection in one horse. It was concluded that the external carotid and maxillary arteries must be occluded on both sides of the eroded segment to prevent hemorrhage from normograde and retrograde flow.
在9匹因咽囊真菌病导致出血的马中，使用球囊导管阻塞颈外动脉及其分支。4匹马在阻塞患侧颈内动脉的同时阻塞了颈外动脉，另外2匹马此前已阻塞了颈内动脉。3匹马中，将一根球囊导管插入咽囊底部下方的颈外动脉，并将其尖端盲目推进至远端分支。1匹马在手术期间通过球囊导管短暂阻塞颞浅动脉，以便将插入颈外动脉的导管转向上颌动脉。在另外5匹马中，通过插入腭大动脉的球囊导管在近端阻塞颈外动脉，并在翼管尾侧立即阻塞上颌动脉。8匹马术后未发生严重出血，但1匹在颈外动脉插入一根球囊导管的马在术后11天出现大量出血，随后实施安乐死。1匹马因持续性吞咽困难而实施安乐死。与使用球囊导管相关的唯一并发症是1匹马出现轻度切口感染。得出的结论是，必须在糜烂段两侧阻塞颈外动脉和上颌动脉，以防止正向和逆向血流导致出血。
