肘后血管网与组织瓣设计的解剖学基础

The posterior elbow vascular network and the flap design:anatomic study

目的:研究肘后血管网对肘后组织瓣的供血作用,为临床设计新的组织瓣提供解剖学基础。方法:通过6例新鲜上肢标本和2例上肢血管铸型标本的解剖,观察肘后血管网的形态学特点及其与肘后组织瓣的供血关系。结果:肘后血管网分为肘后内侧血管网和肘后外侧血管网,分别发出骨膜支和肌皮穿支到肘后相关组织瓣区,肘后内侧血管网吻合处外径在(1.8±0.3)mm;肘后外侧血管网吻合处外径在(0.9±0.4)mm。肘后内、外侧血管网之间吻合处外径在0.3～0.9mm。结论:根据肘后血管网吻合特点,可为临床设计出不带桡侧副动脉背侧支的外侧筋膜骨膜瓣、不带尺侧返动脉背侧支的内侧筋膜骨膜瓣和骨间返动脉骨膜支的鹰嘴骨膜皮瓣等组织瓣。

Objective： To investigate anatomic characteristics of the posterior elbow vascular network and its clinical discussion to the blood supply based flaps of the posterior elbow. Methods： Six fresh specimens and two injected upper limb were studied. Observations were emphasized on the posterior elbow vascular network and their connections with the blood supply based flaps of the posterior elbow. Results： The posterior elbow vascular network was abundant and formed by multiple source vessels, which were identified to the medial and the lateral vascular network of the posterior elbow. The diameter of the vascular network was 0.3--0.9 ram. Conclusions： According to the posterior elbow vascular network, different based flaps without the main vessels could be designed.
