To report a case of a patient with May-Thurner syndrome who underwent endovenous stenting and was found to have pulsating arterial compression on the venous stent.
A 74-year-old man presented with 18 months of progressive right thigh and calf edema. After an extensive work-up, the patient underwent a venogram with intravascular ultrasound (IVUS), revealing compression of the right iliac vein by the external iliac artery and psoas muscle. Following stent deployment, fluoroscopy revealed extrinsic compression by an artery, but IVUS confirmed sufficient stent expansion. On follow-up, there was a significant resolution of right limb edema, and adjacent arterial pulsation/compression was deemed non-significant.
The choice of venous stents is essential to prevent collapse from extrinsic compression, such as that from an adjacent artery.Clinical ImpactCarefully choosing venous stents is essential to ensure stent patency in the face of external compression.
报告一例患有May-Thurner综合征的患者，该患者接受了静脉内支架置入术，结果发现静脉支架上存在搏动性动脉压迫。
一名74岁男性出现进行性右大腿和小腿水肿18个月。经过全面检查后，该患者接受了血管造影和血管内超声检查（IVUS），结果显示右髂静脉受到髂外动脉和腰大肌的压迫。支架置入后，荧光透视显示有动脉外部压迫，但IVUS证实支架充分扩张。随访时，右下肢水肿明显消退，相邻动脉搏动/压迫被认为不明显。
静脉支架的选择对于防止外部压迫（如相邻动脉的压迫）导致的塌陷至关重要。临床影响仔细选择静脉支架对于确保在存在外部压迫的情况下支架通畅至关重要。
