目的探讨经桡动脉途径前列腺动脉栓塞术(PAE)治疗前列腺增生的可行性及安全性。方法回顾性分析18例经左侧或右侧桡动脉行C形臂CT引导下PAE术患者临床资料,观察记录上肢动脉痉挛、损伤和穿刺点出血发生率,术后桡动脉搏动及堵塞情况,手指血供及神经损伤情况,手术成功率,围手术期脑血管并发症发生率,手术时间,射线辐射剂量及临床疗效。结果 18例患者中接受经左侧桡动脉、右侧桡动脉途径PAE术分别为14例、4例。16例接受双侧栓塞,2例因前列腺动脉开口扭曲伴狭窄仅完成单侧栓塞。术后1例出现桡动脉搏动减弱,超声提示血流减慢。手术时间96~245 min,患者所受辐射剂量2 435~4 958 m Gy,平均(3 342±156)m Gy,与同期经股动脉途径PAE术差异无统计学意义(P=0.1167)。结论采用经桡动脉途径行PAE术安全、可行。
Objective To investigate the feasibility and safety of transradial arterial embolization (PAE) for benign prostatic hyperplasia. Methods The clinical data of 18 patients with PAE underwent C-arm CT guided by left or right radial artery were retrospectively analyzed. The incidence of upper extremity arterial spasm, injury and puncture site bleeding, postoperative radial artery pulsation and occlusion, Finger blood supply and nerve injury, operation success rate, perioperative cerebrovascular complications, operation time, radiation dose and clinical efficacy. Results 18 patients received radial artery via the left and right radial artery PAE were 14 cases, 4 cases. Sixteen patients underwent bilateral embolization, and two received unilateral embolization because of tortuosity in the prostatic artery with stenosis. Radial artery pulsatility was attenuated in 1 case after operation, and ultrasound showed slowed blood flow. There was no significant difference between the two groups (P = 0.1167). The operation time ranged from 96 to 245 min. The radiation dose ranged from 2 435 to 4 958 m Gy (mean, 3 342 ± 156) m Gy. Conclusions Transradial PAA is safe and feasible.
