血管畸形,其中包括淋巴或血管系统疾病,可以以各种方式出现在射线照片上,在放射科,和组织学。具有直接动静脉连接的高流量病变被称为动静脉畸形(AVM)。这些病变会导致软组织丢失和畸形,因为它们很难早期诊断。该病例报告描述了一名75岁的女性,她的上唇出现严重的蓝紫色肿胀。在进行了彻底的调查之后,患者的病情很快被确定为AVM。经USG多普勒和组织学检查确认后,该患者接受了成功的手术切除,发现了提示AVM的狭窄血管病变。讨论探讨了导致AVM形成的血液动力学和胚胎学因素,指出血流动力学特性和临床症状的差异。治疗选择受根据临床标准和血管造影血流特征对外周AVM进行分类的影响。
Vascular malformations, which include disorders of the lymphatic or vascular systems, can appear in a variety of ways on radiographs, in the radiological department, and histologically. High-flow lesions with direct arteriovenous connections are known as arteriovenous malformations (AVMs). These lesions can cause soft tissue loss and deformity since they are difficult to diagnose early. This case report describes a 75-year-old female who presented with a severe bluish-purple swelling on her top lip. After conducting a thorough investigation, the patient\'s condition was quickly identified as AVM. After confirmation by USG Doppler and histological examination, the patient underwent a successful surgical resection that revealed a confined vascular lesion suggestive of AVM. The discussion explores the hemodynamic and embryologic factors that contribute to the formation of AVM, pointing out differences in hemodynamic properties and clinical symptoms. Treatment choices are influenced by the categorization of peripheral AVMs according to clinical standards and angiographic flow characteristics.
