B-mode ultrasound was prospectively evaluated for its ability to preoperatively assess the adequacy of venous conduit for arterial reconstruction. Fifty-one patients who had lower extremity revascularization had real-time imaging of the saphenous and cephalic veins. Veins were judged adequate based on size, compressibility, and absence of sclerosis or intraluminal echoes. All mapped veins were explored and assessed by the standard criteria for suitability. Vein size was determined from completion angiograms, and wound complications recorded and compared with patients who had similar procedures in the 12 months before the use of vein mapping. Preoperative mapping was found to be accurate in 50 to 51 patients (98%). Vein size as determined by B-mode ultrasound correlated well with angiograms, R = 0.8539 overall with R greater than 0.9 in the last 7 months of the study. Wound complications occurred in 2% of the patients who had preoperative mapping and in 17% of the historic controls. Preoperative vein mapping using B-mode ultrasound is an accurate method of determining vein suitability for use in arterial reconstruction. It improves operative planning and can contribute to a reduction in wound complications. Veins determined to be unusable by preoperative scanning need not be explored.
对B超术前评估静脉导管用于动脉重建的充分性的能力进行前瞻性评估。51例接受下肢血管重建的患者接受了大隐静脉和头静脉的实时成像。根据静脉大小、可压缩性以及有无硬化或腔内回声来判断静脉是否合适。所有标记的静脉均按照标准的适用性标准进行探查和评估。根据血管造影完成情况确定静脉大小，并记录伤口并发症情况，并与在使用静脉标记前12个月内接受类似手术的患者进行比较。术前标记在50至51例患者（98%）中被发现是准确的。B超确定的静脉大小与血管造影结果相关性良好，总体相关系数R = 0.8539，在研究的最后7个月中R大于0.9。术前标记的患者伤口并发症发生率为2%，历史对照患者为17%。使用B超进行术前静脉标记是确定静脉是否适合用于动脉重建的一种准确方法。它改善了手术规划，并有助于减少伤口并发症。术前扫描确定不可用的静脉无需探查。
