It is unknown whether if a plain X-ray of the iliac arteries (pelvic X-ray) is a reliable tool to detect calcifications and predict vascular complications.
In a prospective study, a pelvic X-ray was performed before transplantation in patients without evidence of peripheral vascular disease (n = 109) and vascular calcifications were scored. Vascular calcifications in the iliac arteries and complications were scored by the transplant surgeon during the operation (gold standard).
Vascular calcifications were found on the pelvic X-ray in 33 patients (30.2%). The transplant surgeon identified vascular calcifications in 35%. Sensitivity and specificity of the pelvic X-ray for vascular calcifications in the iliac arteries were 48 and 82%, respectively. Technical problems with the arterial anastomosis due to vascular calcifications were observed in five patients. The negative predictive value and positive predictive value of a pelvic X-ray for complications with the arterial anastomosis were 99 and 14%, respectively.
A pelvic X-ray is not a reliable tool to detect vascular calcifications. Technical problems with the arterial anastomosis due to calcifications are infrequent in the absence of vascular calcifications on the pelvic X-ray.
髂动脉平片（骨盆 X 光片）是否能可靠地检测钙化并预测血管并发症尚不清楚。
在一项前瞻性研究中，对无外周血管疾病证据的患者（n=109）在移植前进行骨盆 X 光检查，并对血管钙化进行评分。血管钙化和并发症由移植外科医生在手术中（金标准）进行评分。
在 33 名患者（30.2%）的骨盆 X 光片上发现了血管钙化。移植外科医生发现血管钙化的比例为 35%。骨盆 X 光片检测髂动脉血管钙化的敏感性和特异性分别为 48%和 82%。由于血管钙化，有 5 名患者的动脉吻合出现技术问题。骨盆 X 光片对动脉吻合并发症的阴性预测值和阳性预测值分别为 99%和 14%。
骨盆 X 光片不是检测血管钙化的可靠工具。在骨盆 X 光片上没有血管钙化的情况下，由于钙化导致的动脉吻合技术问题很少见。
