Abstract:
The superficial temporal artery (STA) bifurcates into frontal and parietal branches. The parietal branch is used as a recipient vessel for scalp reconstruction, but it is absent in approximately 16.3% of individuals. In this case, a 72-year-old woman with an occipital scalp defect lacked both the parietal branch of the STA and the superficial temporal vein. To address this anatomic variation, we used the frontal branch of the STA and the posterior auricular vein as alternative recipient vessels for anterolateral thigh free flap reconstruction. The surgical procedure involved end-to-end microvascular anastomosis of one artery and one vein. Partial flap necrosis occurred postoperatively, but eventually resolved with debridement. The frontal branch of the STA and the posterior auricular vein can serve as reliable alternatives in the absence of the parietal branch. Reconstructive surgeons should be aware of anatomic variations of the STA and adapt their surgical approach accordingly.
摘要:
颞浅动脉(STA)分为额叶和顶叶分支。顶支用作头皮重建的受体血管,但在大约16.3%的个体中不存在。在这种情况下,一位72岁的枕骨头皮缺损的女性既缺乏STA的顶支,也缺乏颞浅静脉。为了解决这种解剖变异,我们使用STA的额支和耳后静脉作为替代受体血管进行股前外侧游离皮瓣重建。外科手术包括一条动脉和一条静脉的端到端微血管吻合。术后出现部分皮瓣坏死,但最终通过清创术解决。在没有顶支的情况下,STA的额支和耳后静脉可以作为可靠的替代方案。重建外科医生应了解STA的解剖变化,并相应地调整其手术方法。
