髂股静脉阻塞解剖分型

慢性静脉阻塞(CVO)是指静脉血流受阻,通常由静脉系统的部分或完全阻塞引起,导致受影响静脉血流减少和压力增加。CVO是一个总称,包括多种状况,如血栓后综合征(PTS)和非血栓性髂静脉病变(NIVLs)。PTS是深静脉血栓形成(DVT)的常见并发症,据估计,约50%的髂股DVT患者在初次诊断后2年内会发展为PTS。PTS的症状可能因阻塞的位置和范围而异,最常见的症状包括肿胀、疼痛、跛行和皮肤变化(如变色或溃疡)。这些症状可能对患者的生活质量和医保构成了重大负担。髂股静脉再通和支架置入术已成为一种有前景的微创介入治疗方法,充分了解患者的髂静脉血管解剖至关重要。本文将介绍髂股静脉闭塞的五种分型.
