Abstract

Background: Tiny arteriovenous (AV) shunts of 10-150 µm (0.01-0.15 mm) are documented in the hands and feet. Larger shunts up to 0.5 mm (500 µm) have been discovered by the authors in the inner canthus and the human eye. This study seeks their possible existence in the upper limb.

Methods: Radiographic lead oxide cadaver injection and dissection studies of 14 archival and six new upper limbs were examined.

Results: AV shunts of 0.1-0.5 mm were discovered between the brachial, ulnar, and radial arteries and their venae comitantes and between their arterial perforators and the subcutaneous veins.

Conclusion: This pilot study provides insight into the possible function of these large AV shunts associated with blood flow variation in temperature, blood pressure, tissue transfer, flap prefabrication, and flap necrosis.

动静脉分流：它们在生理学、病理学和组织转移中的位置和作用。上肢的初步报告。

背景：手部和足部有 10-150 微米（0.01-0.15 毫米）的微小动静脉分流。作者在内眼角和人眼中发现了更大的分流，可达 0.5 毫米（500 微米）。本研究旨在寻找上肢中可能存在的分流器：方法：对 14 个存档上肢和 6 个新上肢进行氧化铅尸体注射和解剖研究：结果：在肱动脉、尺动脉和桡动脉与其合并静脉之间，以及动脉穿孔器与皮下静脉之间发现了0.1-0.5毫米的房室分流：这项试验性研究有助于深入了解这些大的房室分流可能与温度、血压、组织转移、皮瓣预制和皮瓣坏死中的血流变化有关的功能。

期刊介绍： Plastic and Reconstructive Surgery—Global Open is an open access, peer reviewed, international journal focusing on global plastic and reconstructive surgery.Plastic and Reconstructive Surgery—Global Open publishes on all areas of plastic and reconstructive surgery, including basic science/experimental studies pertinent to the field and also clinical articles on such topics as: breast reconstruction, head and neck surgery, pediatric and craniofacial surgery, hand and microsurgery, wound healing, and cosmetic and aesthetic surgery. Clinical studies, experimental articles, ideas and innovations, and techniques and case reports are all welcome article types. Manuscript submission is open to all surgeons, researchers, and other health care providers world-wide who wish to communicate their research results on topics related to plastic and reconstructive surgery. Furthermore, Plastic and Reconstructive Surgery—Global Open, a complimentary journal to Plastic and Reconstructive Surgery, provides an open access venue for the publication of those research studies sponsored by private and public funding agencies that require open access publication of study results. Its mission is to disseminate high quality, peer reviewed research in plastic and reconstructive surgery to the widest possible global audience, through an open access platform. As an open access journal, Plastic and Reconstructive Surgery—Global Open offers its content for free to any viewer. Authors of articles retain their copyright to the materials published. Additionally, Plastic and Reconstructive Surgery—Global Open provides rapid review and publication of accepted papers.
