Pseudoaneurysms are vascular injuries resulting from a rupture of the vessel walls with blood extravasation into perivascular tissues. Proper treatment is required to prevent rupture and intense bleeding. This article reports a case of pseudoaneurysm of the facial artery that evolved to a late complication, presenting dehiscence of suture and exposure of the wound and bleeding after the initial injury and also discusses the effects of vascular response from the involved vessels by comparing them against the contralateral side.
A healthy 17-year-old male was admitted with an injury of approximately 35 mm in length in the right cheek with an exposed clot inside the injury and local bleeding after a stabbing 11 days before. CT angiography showed rupture of the facial artery and formation of a pseudoaneurysm with an organized clot. The patient was treated by means of surgery under local anesthesia and intravenous sedation. The facial artery was located and attached by suture. The wound was explored and clots were removed. The patient was discharged on the first postoperative day and he had an excellent scarring standard with no unfavorable event.
The authors conclude that this surgical technique is an effective method for treating such injuries, as it is easily performed and can be conducted by the oral and maxillofacial surgeon assistant.
假性动脉瘤是血管壁破裂导致血液渗入血管周围组织而引起的血管损伤。需要进行适当治疗以防止破裂和大出血。本文报告一例面动脉假性动脉瘤病例，该病例发展为晚期并发症，在初始损伤后出现缝线裂开、伤口暴露和出血，并通过与对侧进行比较讨论了受累血管的血管反应的影响。
一名健康的17岁男性因11天前刺伤后右侧脸颊有一处约35毫米长的伤口入院，伤口内有血凝块暴露且局部出血。CT血管造影显示面动脉破裂并形成假性动脉瘤，伴有机化血凝块。患者在局部麻醉和静脉镇静下接受手术治疗。找到面动脉并进行缝合。探查伤口并清除血凝块。患者术后第一天出院，瘢痕形成标准良好，未发生不良事件。
作者得出结论，这种手术技术是治疗此类损伤的有效方法，因为它操作简便，可由口腔颌面外科助理医师进行。
