高位结扎剥脱及腔内激光联合治疗大隐静脉曲张97例

目的:比较高位结扎、剥脱及腔内激光联合治疗与传统高位结扎、曲张静脉剥脱术治疗大隐静脉曲张的结果.方法:对126例运用高位结扎并曲张静脉剥脱治疗大隐静脉曲张及97例运用高位结扎、部分严重曲张静脉剥脱并部分轻度曲张大隐静脉腔内激光烧灼治疗大隐静脉曲张患者的临床资料、治疗方法及疗效进行回顾性分析.结果:传统治疗组治愈154条患肢,治愈率93.33%;术后残留浅静脉曲张患肢11条,占6.67%.联合治疗组治愈116条患肢,治愈率95.87%;发现5条术肢残留静脉曲张,占4.13%.结论:联合运用高位结扎、部分严重曲张静脉剥脱及腔内激光治疗大隐静脉曲张,其治愈率和有效率与单纯运用高位结扎并静脉剥脱术无明显差别.但后者手术适应证宽,手术时间短,手术出血量小,术后恢复快,术后皮肤外表美观度均优于前者.     

腔内激光治疗下肢静脉曲张175例

下肢静脉曲张是血管外科的一种常见疾病，大隐静脉高位结扎并分段剥脱术是治疗该病的经典传统术式，但创伤大、切口多、欠美观。静脉腔内激光治疗（Endovenous laser treatment，EVLT）是治疗下肢静脉曲张的微创手术方法，2006—05～2007—12，我院应用英国Diomed公司生产的半导体激光治疗仪治疗下肢静脉曲张175例210条肢体，疗效满意。

目的探讨下肢静脉腔内激光治疗（Endovenous Laser Treatment,EVLT）联合大隐静脉（Great Saphenous Vein,GSV）高位结扎治疗原发性下肢静脉曲张术后是否需要抗凝治疗。方法本实验设计为前瞻性的随机对照临床研究,将原发性下肢静脉曲张患者189例,随机分为对照组（A组）,患者96例;抗凝组（B组）,患者93例。两组患者均进行静脉腔内激光治疗及大隐静脉高位结扎术,B组患者术后给予皮下注射低分子肝素,A组术后不给予低分子肝素,其它处理相同。观察两组患者术后3d、2周和3个月术肢有无深静脉血栓形成。所有患者随访时间3个月。结果189例原发性下肢静脉曲张患者,在术后随访期间,仅A组有1例发生术肢深静脉血栓形成（Deep Vein Thrombosis,DVT）;其余无一例发生DVT和肺栓塞。A、B两组间术后下肢深静脉血栓形成发病率无显著性意义（P〉0．05）。结论腔内激光联合高位结扎治疗原发性下肢静脉曲张术后是否应用抗凝药物对预防下肢深静脉血栓形成没有显著性影响,术后不需要常规应用抗凝药物。     

110例大隐静脉曲张高位结扎剥脱联合腔内激光治疗的护理

下肢静脉曲张是指下肢的浅静脉系统--大隐静脉、小隐静脉及其分支处于伸长、蜿蜒和扩张状态[1],传统的手术方法是大隐静脉高位结扎加分段剥脱术.静脉腔内激光治疗(endovenous laser treatment,EVLT)是将激光光导纤维直接插入静脉腔内,对曲张静脉进行腔内治疗的全新方法[2].我科于2007～2010年采用高位结扎、部分曲张静脉剥脱及部分静脉腔内激光治疗大隐静脉曲张110例,经过术前、术后的精心护理,取得了较满意的效果,现将护理体会总结如下.

The 1,470-nm Bare-Fiber Diode Laser Ablation of the Great Saphenous Vein and Small Saphenous Vein at 1-Year Follow-up Using 8–12 W and a Mean Linear Endovenous Energy Density of 72 J/cm

PurposeTo demonstrate 1-year outcomes after low-energy endovenous laser ablation (EVLA) of incompetent saphenous veins with linear endovenous energy density (LEED) of 80 J/cm or lower with the use of a 1,470-nm diode laser.Materials and MethodsIncompetent saphenous veins in 236 patients (355 limbs; Clinical/Etiology/Anatomy/Pathophysiology classifications of C2–C4) were treated by EVLA with a bare-tipped 1,470-nm laser with LEED no greater than 80 J/cm (mean, 72.4 J/cm) and laser power of 8–12 W. Patients were evaluated clinically and with duplex ultrasonography at 1 week and 1, 3, 6, and 12 months after EVLA to assess the technical and clinical success and complication rates.ResultsIn the 355 limbs, the technical success rate was 100%. The great saphenous vein (GSV) remained occluded in all 229 limbs (100%) after 1 week, 202 of 203 limbs (99.5%) after 1 month, 157 of 158 limbs after 3 months (99.3%), all 99 limbs after 6 months (100%), and all 41 limbs after 1 year (100%). The small saphenous vein (SSV) remained occluded in all 103 limbs (100%) after 1 week, all 94 limbs (100%) after 1 month, 68 of 69 limbs (98.5%) after 3 months, 40 of 41 limbs (97.5%) after 6 months, and all 14 limbs after 1 year (100%). Two GSVs and two SSVs were recanalized and underwent repeated EVLA. No major complications occurred, although bruising (21% of cases), pain (15%), and paresthesia (4%) were observed.ConclusionsLow-energy EVLA with the use of a 1,470-nm laser with LEED of 80 J/cm or lower is an effective, safe, and technically successful option for the treatment of incompetent saphenous veins.

Suitability of Varicose Veins for Endovenous Treatments

The aim of the study was to assess the suitability of radiofrequency ablation (RFA), endovenous laser ablation (EVLA), and foam sclerotherapy (FS) for patients with symptomatic varicose veins (VVs). The study comprised 403 consecutive patients with symptomatic VVs. Data on 577 legs from 403 consecutive patients with symptomatic VVs were collected for the year 2006. Median patient age was 55 years (interquartile range 45–66), and 62% patients were women. A set of criteria based on duplex ultrasonography was used to select patients for each procedure. Great saphenous vein (GSV) reflux was present in 77% (446 of 577) of legs. Overall, 328 (73%) of the legs were suitable for at least one of the endovenous options. Of the 114 legs with recurrent GSV reflux disease, 83 (73%) were suitable to receive endovenous therapy. Patients with increasing age were less likely to be suitable for endovenous therapy (P = 0.03). Seventy-three percent of patients with VVs caused by GSV incompetence are suitable for endovenous therapy.

Endovenous laser ablation of the great saphenous vein with a 980-nm diode laser in continuous mode: early treatment failures and successful repeat treatments

PURPOSE: To investigate the efficacy of lower-energy endovenous laser treatment for great saphenous vein (GSV) incompetence and treatment parameters associated with early treatment failure. MATERIALS AND METHODS: Sixty consecutive endovenous laser treatments (32 left, 28 right; 57 initial treatments, three repeat treatments) in 48 patients (13 men, 35 women; mean age, 55.2 +/- 12.9 years), with bilateral treatments in nine patients, were studied. Preprocedural clinical signs, etiology, anatomy, and physiologic classifications demonstrated class 2 limbs in 11.7% of cases, class 3 limbs in 25.0%, class 4 limbs in 48.3%, and class 5 limbs in 15.0%. All initial and repeat treatments were performed with lower-energy with use of a 980-nm diode endovenous laser at 11 W in continuous mode. Patients wore class II compression stockings for 2 weeks and were followed up at 1, 3, and 6 months with clinical and duplex ultrasound examinations. Treatment failures were diagnosed at 3 months on the basis of GSV patency or lack of clinical improvement. Diameter and length of GSV treated, treatment energy parameters, and clinical outcomes were prospectively measured and compared between successful and failed treatments. RESULTS: The initial treatment success rate was 94.7% (54 of 57). The mean maximum diameter of successfully treated GSVs was 1.12 +/- 0.52 cm, and the mean maximum diameter of GSVs in which treatment failure occurred was 2.05 +/- 0.23 cm (P = .008). Mean total energy applied for successful treatments was 1,131.3 +/- 248.1 J, and mean total energy applied for failed treatments was 1,439.6 +/- 425.0 J (P = 0.053). Mean unit energy applied for successful treatments was 32.7 +/- 7.5 J/cm, and that for failed treatments was 32.8 +/- 4.9 J/cm (P = .986). All patients in whom treatment failed were successfully treated again with a mean total energy of 1,393.0 +/- 81.0 J and a mean unit energy of 29.4 +/- 4.9 J/cm. There were no significant differences in mean total energy or unit energy applied among successful, failed, and repeat treatments (P > .05). Mean follow-up duration was 6.8 months. CONCLUSIONS: Endovenous laser treatment with lower energy appears to be safe and effective. Larger GSV diameter is associated with early treatment failures.
