Exposed prosthetic grafts are a challenge to vascular specialists. Groin dissections in vascular surgery can lead to local tissue breakdown, especially in patients who have multiple comorbidities and poor nutritional status. In this report, we describe a patient with exposed prosthetic bypass conduits in the groin region which was successfully covered with bilateral myocutaneous flaps. A 75-year-old Sri Lankan male with diabetes, hypertension and Parkinson's disease presented with bilateral non-healing wound and rest pain for 3 months. Since his premorbid status precluded the aortic cross-clamping and aorto-bifemoral graft, a decision was made to perform a right axillo-bifemoral bypass using a prosthetic graft. Re-operation was required for graft thrombectomy on the same day of surgery. His post-operative period was complicated with lymph leak and surgical site infection of bilateral groin wounds which ultimately led to exposed prosthetic graft which was fortunately patent. After optimizing his nutritional status and comorbidities, he underwent bilateral rectus femoris myocutaneous flaps to cover the soft-tissue defect over the exposed prosthetic grafts. His initial post-operative period was unremarkable except for a small area of skin breakdown. Myocutaneous flaps are preferred as they are more resilient to breakdown compared to facio-cutaneous flaps, especially in a patient with compromised blood supply. The type of loco-regional flap should be carefully selected in an individualized manner depending on the regional vascularity. The rectus femoris flap is a suitable option in terms of ease of surgical technique and durability. Comorbidities and local factors should be optimized prior to definitive reconstruction to maximize the chances for optimal wound healing.
外露的人工血管移植物对血管外科专家来说是一项挑战。血管外科中的腹股沟解剖可能导致局部组织破损,尤其是在患有多种合并症且营养状况较差的患者中。在本报告中,我们描述了一名腹股沟区域人工血管旁路移植物外露的患者,该患者通过双侧肌皮瓣成功覆盖。一名75岁患有糖尿病、高血压和帕金森病的斯里兰卡男性,出现双侧伤口不愈合及静息痛3个月。由于其病前状态不适合进行主动脉交叉钳夹和主动脉-双股动脉移植,决定使用人工血管进行右腋-双股动脉旁路移植术。术后当天因移植物血栓形成需要再次手术。他的术后出现了淋巴漏和双侧腹股沟伤口手术部位感染等并发症,最终导致人工血管移植物外露,但幸运的是移植物仍保持通畅。在优化其营养状况和合并症后,他接受了双侧股直肌肌皮瓣移植,以覆盖外露人工血管移植物上的软组织缺损。除了一小片皮肤破损外,他术后初期情况良好。与筋膜皮瓣相比,肌皮瓣更能抵抗破损,因此更受青睐,尤其是在血供受损的患者中。应根据局部血管情况个体化地仔细选择局部皮瓣的类型。就手术技术的简易性和耐用性而言,股直肌皮瓣是一个合适的选择。在进行确定性重建之前,应优化合并症和局部因素,以最大程度地提高伤口最佳愈合的机会。
