Sixty-three patients undergoing femoro-popliteal bypass using autologous vein were prospectively screened for the development of graft related strictures by clinical assessment, intravenous digital subtraction angiography (IVDSA) and Duplex scanning. Eighteen strictures were identified in 14 grafts. Clinical examination detected only 11% of lesions, IVDSA detected 83% of lesions and Duplex scanning detected all 18 lesions. Seventeen lesions had occurred by 6 months from the time of operation which suggests that screening should begin early. Treatment by percutaneous transluminal angioplasty (PTA) was offered for eight strictures and dilatation was complete in all cases. No stricture recurred in the follow-up period. Cumulative patency in this series of screened and selectively treated vein grafts was compared with a previous series of 216 femoro-popliteal vein grafts and an improvement in 1 year potency of 15% was achieved (log rank test, chi 2 = 5.12, P = 0.02).
对63例行自体静脉股腘动脉搭桥术的患者进行前瞻性筛查，通过临床评估、静脉数字减影血管造影（IVDSA）和双功超声扫描来检测移植物相关狭窄的发生情况。在14条移植物中发现了18处狭窄。临床检查仅检测出11%的病变，IVDSA检测出83%的病变，双功超声扫描检测出了所有18处病变。17处病变在术后6个月内出现，这表明筛查应尽早开始。对8处狭窄进行了经皮腔内血管成形术（PTA）治疗，所有病例均完成了扩张。随访期间无狭窄复发。将这一系列经筛查和选择性治疗的静脉移植物的累积通畅率与先前的216例股腘静脉移植物系列进行比较，1年通畅率提高了15%（对数秩检验，卡方=5.12，P=0.02）。
