Observation on Firearm Injury of Maxillofacial Microvasculature with Electron Microscopy / 第三军医大学学报

ABSTRACT

The injurious changes of the microvasculature in the maxillofacial region due to high-velocity bullet injury were observed in different time intervals with scanning and transmission electron microscopy. It was found that there were microthrombus formation in the vascular lumen, and endothelial loss and dege-neration or necrosis of the vascular wall in the microvasulature around the wound. Our findings indicate that when early reconstructive surgery for the tissue defect due to gunshot wound especially for those in the maxillofacial region is to be performed with microsurgical technique, it is essential for the surgeon to realize and consider the wounding condition on the microvasculature of the recipient site.
