Ultrasound-guided femoral block in patients undergoing radiofrequency ablation of incompetent saphenous veins: A randomized controlled trial

ObjectiveTo evaluate the benefit of ultrasound-guided femoral nerve block (UGFN) for reducing pain in patients undergoing radiofrequency ablation (RFA).MethodsPatients age 18–70 years scheduled for RFA were prospectively enrolled. Patients were randomly assigned to the UGFN or control group at a 1:1 ratio, and stratified according to concomitant phlebectomy procedure. The pain score and amount of fentanyl use during the operation were recorded. Pain severity and quadriceps muscle strength were recorded at 2-, 6-, and 12-hours postoperation.ResultsTwenty-four patients in each group were included. Moderate to severe pain during surgery was found in 16 (66.7%) patients in the control group, and in 2 (8.3%) patients in the UGFN group (p < 0.001). Fentanyl use during surgery was significantly higher in controls than in UGFN patients (107.29 ± 40.70 μg vs. 42.71 ± 26.04 μg, respectively; p < 0.0001). The postoperative pain score was not significantly different between groups. In the UGFN group, quadriceps femoris weakness was found in 19 (79.2%) patients, and in 1 (4.2%) patient at 2-hours and 6-hours postoperation, respectively. No patient in the control group had quadriceps femoris weakness.ConclusionUGFN decreased intraoperative pain during RFA. However, patients undergoing UGFN should be observed in the hospital for at least 6 hours, and quadriceps muscle power should be tested before hospital discharge.     

Single-visit endovenous laser treatment and tributary procedures for symptomatic great saphenous varicose veins

Introduction

Endovenous ablation of saphenous varicose veins has decreased morbidity and recovery time compared with open surgery. This study assessed the outcome and mid-term patient satisfaction of single-visit endovenous laser treatment (EVLT) alone, EVLT combined with phlebectomies and endovenous chemical ablation.

Methods

A retrospective review was conducted of all patients (n=91) in 2008–2009 who underwent single-visit day-case EVLT using local anaesthesia under a single surgeon. Postoperative venous ultrasonography at 2 and 14 months was reviewed. A telephone questionnaire was carried out to assess recurrence of symptoms and quality of life at 42 months.

Results

Overall, 124 limbs underwent day-case EVLT under local anaesthesia using an 810nm diode laser at a continuous setting of 14W. Forty-eight of these underwent EVLT alone while fifty underwent EVLT with phlebectomies and twenty-six underwent EVLT with endovenous chemical ablation. Ninety-one per cent of limbs underwent two-month postoperative imaging. All had satisfactory great saphenous vein (GSV) ablation (anterior thigh vein patency: n=1). The majority (84%) of limbs underwent 14-month imaging with a 98% GSV ablation rate. Three per cent had anterior thigh vein and saphenofemoral junction incompetence. Recurrence of GSV patency and reflux was <1%. The response rate to the questionnaire was 60%: 95% of respondents confirmed improvement following treatment, 62% remained symptom free at 42 months while 65% of patients with a return of symptoms deemed them mild. The questionnaire was scored out of 56 for symptoms and quality of life. Those with symptoms scored significantly higher.

Conclusions

At 42 months, the majority of limbs remained asymptomatic. The short-term GSV ablation rates were excellent. Overall mid-term review of patients has shown a well received single-visit service with concomitant phlebectomy or endovenous ablation, and good ablation and patient satisfaction rates.

射频消融术与大隐静脉高位结扎剥脱术治疗下肢静脉曲张的疗效比较

背景与目的 大隐静脉高位结扎剥脱术（HSL）是治疗下肢静脉曲张的经典术式,但存在创伤较大、恢复时间较长、切口瘢痕不美观等缺点。随着医疗技术的进步,以腔内热消融治疗为代表的微创治疗技术蓬勃发展。本研究旨在对比射频消融术（RFA）与传统HSL治疗下肢静脉曲张的临床疗效。方法 回顾性分析2021年5月—2022年6月期间因原发性下肢静脉曲张于首都医科大学附属北京安贞医院血管外科行手术治疗的272例患者（298条肢体）的临床与随访资料,其中96例（100条肢体）行RFA治疗（RFA组）,176例（198条肢体）行HSL治疗（HSL组）。比较两组患者的术前临床特征、手术情况、并发症情况、临床表现-病因学-解剖学-病理生理学（CEAP）分级、静脉临床严重程度评分（VCSS）和慢性静脉功能不全问卷-14问版（CIVIQ-14）评分的变化情况。结果 两组技术成功率均为100%,术后3 d复查超声提示大隐静脉主干缺如/闭合率为100%。共完成随访265例（290条肢体）,平均随访时间（13.2±3.8）个月,随访期间超声提示大隐静脉主干缺如/闭合率为100%。两组患者的基本临床特征无明显差异（均P>0.05）;与HSL组比较,RFA组术中出血量（21.3 mL vs. 46.8 mL）、术后第1天疼痛评分（3.1 vs. 3.3）、总并发症发生率（25.5% vs. 38.0%）及皮肤感觉异常发生率（5.1% vs. 24.0%）均明显降低（均P<0.05）,RFA组的深静脉血栓形成发生率升高（5.1% vs. 0,P<0.05）;术后所有患者CEAP分级均较术前降级,RFA组81.7%的患肢降级为C0~C1级,HSL组83.9%的患肢降级为C0~C1级;所有患者的VCSS和CIVIQ-14评分均较术前有所改善,且HSL组的VCSS评分改善程度大于RFA组（均P<0.05）。结论 RFA短期疗效与HSL相当,相对于HSL而言,创伤更小、疼痛感更轻、并发症发生率更低,是一种下肢静脉曲张的有效治疗方案。     

123例婴幼儿快速型心律失常行导管射频消融术的麻醉管理

目的 探讨婴幼儿快速型心律失常行导管射频消融术(radiofrequency catheter ablation,RFCA)的麻醉特点及管理. 方法 回顾性分析2004年8月～2016年8月123例在我院接受心内电生理检查及RFCA的快速性心律失常患儿的临床资料.患儿均给予静脉吸入复合麻醉联合喉罩控制通气,记录患儿的手术成功率、手术时间、麻醉时间及相关并发症.结果 123例患儿中共有109例(88.6％,109/123)完成了RFCA,消融成功104例,成功率95.4％(104/109);平均手术时间为(86.38±33.52) min,平均麻醉时间为(92.28±37.19) rmin;麻醉后因未能诱发出心动过速导致未行消融术共计6例(4.9％,6/123).术后拔管苏醒期发生躁动5例,为拔出喉罩后喉痉挛,其中4例患儿加深麻醉后喉痉挛解除,自主呼吸恢复后返回病房,1例患儿加深麻醉后喉痉挛未能解除,经再次插入气管插管,带管返ICU,3h后顺利拔管返回病房.3例患儿术后出现恶心呕吐.结论 婴幼儿快速性心律失常行RFCA的麻醉管理要求高、风险大,麻醉相关并发症发生率较高.良好的循环、气道管理,合理的麻醉药物选择,是此类手术麻醉的管理要点.     

射频闭合与传统剥脱术治疗下肢静脉曲张的对照研究

目的评价射频闭合(radiofrequency endovenous obliteration,RFO)的疗效。方法 56例(56条肢体)大隐静脉曲张患者随机分为两组,每组28例。RFO组利用射频能量使大隐静脉全程闭合,静脉剥脱组用传统方法高位结扎剥脱大隐静脉。两组病例小腿散在的曲张浅静脉均采用点式剥脱处理。比较两组病例的切口数、术后疼痛、平均住院日和短期疗效等情况。结果 RFO组平均切口少、术肢疼痛轻、无皮下血肿,术后平均住院日(2．50±1．00)d。静脉剥脱组的术后平均住院日(4．14±0．85)d。结论 RFO闭合大隐静脉具有创伤小、恢复快、腿部少留瘢痕等优点,是一种可部分替代传统大隐静脉高位结扎剥脱术的有效方法。

Surgery for atrial fibrillation using radiofrequency catheter ablation: assessment of results at one year

Objective: The results obtained in 43 patients using direct intraoperative radiofrequency catheter ablation, as an alternative to surgical incisions, to perform atrial fibrillation surgery, are presented. Methods: Forty-three patients with ages ranging from 43 to 74 years ( ), with chronic atrial fibrillation with an average duration 6±5 years were operated. Eleven patients suffered from clinically relevant tachyarrythmia and eight had previous thromboembolic events. All but one patient had concomitant mitral valve surgery. Direct intraoperative radiofrequency catheter ablation was used to perform endocardial bilateral isolation of the pulmonary veins from the left atrium. Results: There were no local or general complications, namely bleeding or thromboembolic events. Of the 33 patients with more than 3 months of follow-up, 36% remained in atrial fibrillation (Santa Cruz score 0); 30% had Score 4; 18% had Score 3; 6% had Score 2; 9% had Score 1. Conclusions: We conclude that the use of intraoperative radiofrequency catheter ablation is fast and safe. Presently, this is our method of choice for surgical treatment of atrial fibrillation in mitral patients.     

Endovenous laser treatment for primary varicose veins

Venous insufficiency of the lower extremities is a highly prevalent condition. Successful treatment of superficial venous insufficiency will most often necessitate treatment of the saphenofemoral junction incompetence with correction of saphenous vein reflux. In the majority of patients it concerns a reflux of the greater saphenous vein. The standard procedure consists of ligation and stripping of the greater saphenous vein combined with with additional phlebec-tomies or ligation of insufficient perforant veins if necessary. Although the standard procedure is widely known and accepted, the postoperative morbidity and postoperative limitations of activity are high. In this context minimally invasive percutaneous endovenous techniques were developed to improve the patients comfort and faster resumption of work. Among these, endovenous laser ablation of the greater saphenous vein is a relatively new procedure. Percutaneous introduction of a laser fiber into the incompetent vein and ablation with pulsed laser energy is far less invasive than stripping.
