Abstract:
Objective To evaluate the clinical value of transarterial catheterization C-arm CT perfusion scanning technique during prostatic artery embolization(PAE)for benign prostatic hyperplasia(BPH).Methods The clinical data of 46 patients with BPH received PAE were analyzed retrospectively.All patients underwent prostatic artery(PA)digital subtraction angiography(DSA)and C-arm CT perfusion scanning to identify PA and prevent non-target organ embolization.The final recognization of PA was consulted by three senior doctors.After C-arm CT confirmation,PA was embolized with 100-300 μm polyvinyl alcohol(PVA)particles or microspheres under fluoroscopy.The postoperative complications and 3-month clinical efficacy were observed.Results A total of 106 vessels were angioraphed in 46 patients,with 83 PA vessels and 23 non-PA vessels.PA was identified by DSA and C-arm CT with sensitivity of 81.9%(68/83)and 100%(83/83),respectively,which showed significance(χ2=22.3,P<0.01).Non-PA was identified by DSA and C-arm CT with specificity of 73.9%(17/23)and 100%(23/23),which showed significance(χ2=9.2,P=0.02).No serious complications were observed and 3-month clincial efficacy was 91.3%.Conclusion Transarterial catheterization C-arm CT perfusion scanning technique can accurately identify PA,reduce PA leakage and prevent non-target organ embolization.
