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.
背景
手部和足部存在记录显示有10 - 150微米（0.01 - 0.15毫米）的微小动静脉（AV）分流。作者在内眦和人眼发现了直径达0.5毫米（500微米）的较大分流。本研究旨在探寻其在上肢可能的存在情况。
方法
对14例存档上肢标本和6例新的上肢标本进行了放射造影剂氧化铅尸体注射及解剖研究。
结果
在肱动脉、尺动脉和桡动脉及其伴行静脉之间以及它们的动脉穿支与皮下静脉之间发现了直径为0.1 - 0.5毫米的AV分流。
结论
这项初步研究为这些与温度、血压、组织转移、皮瓣预制和皮瓣坏死时血流变化相关的大型AV分流的可能功能提供了见解。
