Unrecognized or untreated vasospasm in microsurgery can lead to flap hypoperfusion and failure. Numerous strategies have been explored for their efficacy in potentiating vasodilation. We present a case of unrecognized vasospasm leading to flap failure followed by a second free flap reconstruction in which severe vasospasm was treated with systemic nicardipine used as an adjunct to other more commonly employed antispasmodics. Although the literature investigating the use of systemic calcium channel blockade in microsurgery is limited, it should be considered an alternative when addressing arterial vasospasm.
显微外科手术中未被识别或未得到治疗的血管痉挛可导致皮瓣灌注不足和坏死。人们已经探索了许多策略来增强血管舒张的效果。我们报告一例未被识别的血管痉挛导致皮瓣坏死的病例,随后进行了第二次游离皮瓣重建,术中使用尼卡地平全身给药作为其他常用解痉药物的辅助治疗,成功治疗了严重的血管痉挛。尽管关于全身应用钙通道阻滞剂在显微外科手术中的研究文献有限,但在处理动脉血管痉挛时应考虑将其作为一种替代方法。
