Experience with vascular pathology and vascular surgery, especially with the use of grafts, is limited in horses. Only one case of a venous aneurysm has been described in the horse, but without successful surgical correction. This case report describes the treatment of a 3-year-old female pony presented with an intermittent localised swelling of the left jugular vein after a previous thrombophlebitis. Ultrasonographic examination revealed a large jugular vein pseudoaneurysm. Treatment consisted of a partial aneurysmectomy preserving the healthy medial wall of the jugular vein. An autologous saphenous vein patch technique was used to reconstruct the vein with the largest possible lumen to minimise thrombus formation. Anticoagulants, antimicrobial and anti-inflammatory drugs were administered pre- and post-operatively. Follow-up ultrasound examinations initially showed local narrowing of the graft. At 2 and 8 months post-operatively, no external deformation of the jugular vein was visible and ultrasonography revealed patent blood flow with only a slight difference in lumen diameter. The patch venoplasty proved a viable surgical technique for jugular vein reconstruction resulting in a sufficient lumen, no thrombus formation and a good cosmetic and functional outcome.

一匹被诊断为颈静脉假性动脉瘤的马的部分动脉瘤切除术和自体补片静脉成形术

血管病理学和血管外科手术的经验，尤其是移植物的使用，在马身上是有限的。在马中只描述了一个静脉动脉瘤病例，但没有成功的手术矫正。本病例报告描述了对一头 3 岁雌性小马的治疗，该小马在先前的血栓性静脉炎后出现左颈静脉间歇性局部肿胀。超声检查发现一个大的颈静脉假性动脉瘤。治疗包括部分动脉瘤切除术，保留颈静脉的健康内壁。自体隐静脉补片技术用于重建具有最大可能管腔的静脉，以尽量减少血栓形成。术前和术后给予抗凝剂、抗菌剂和抗炎药。后续超声检查最初显示移植物局部变窄。术后 2 个月和 8 个月，颈静脉未见外部变形，超声检查显示血流畅通，管腔直径仅有轻微差异。补片静脉成形术被证明是一种可行的颈静脉重建手术技术，可产生足够的管腔、无血栓形成以及良好的美容和功能结果。
