ABSTRACT
Objective To evaluate the feasibility and safety of prostatic artery embolization (PAE)via transradial approach in treating prostatic hyperplasia.Methods The clinical data of 18 patients with prostatic hyperplasia,who received C-arm CT-guided PAE via left or right radial artery access,were retrospectively analyzed.The following indexes were recorded:arterial spasm and injury of upper limbs,incidence of puncture point bleeding,postoperative radial artery pulse and congestion,blood supply and nerve injury of fingers,the surgical success rate,incidence of perioperative cerebral vascular complications,operation time,radiation dose and clinical curative effect.Results Among the 18 patients,PAE via left radial artery access was employed in 14,and PAE via right radial artery access was performed in 4.Bilateral PAE was carried out in 16 patients,and only unilateral PAE was able to be successfully accomplished in 2 patients as the prostatic artery opening of the other side was tortuous with stenosis.After PAE,decreased radial pulse was observed in one patient and ultrasound examination revealed decreased blood flow.The operation time ranged from 96 min to 245 min.The radiation dose received by the patient varied from 2435 mGy to 4958 mGy with a mean of (3342±156) mGy,which was not significantly different from the radiation dose received by the patients who underwent PAE via femoral artery access during the same study period (P=0.1167).Conclusion In treating prostatic hyperplasia,PAE by using transradial approach is clinically safe and technically feasible.
