Percutaneous transpopliteal venography

The authors advocate percutaneous transpopliteal venography as a new method for evaluating the function of deep venous valves of the lower extremity. At the popliteal fossa, the popliteal vein was punctured and a catheter was inserted cephaladly for venographic study of the valves. By this method, not only the ilio-femoropopliteal vein was clearly visualized, also the competence of the valves in this venous segment may accurately be tested one by one, thus making up the shortcomings of the ascending and descending venography. It was found, through this venography, that even if the highest valve of the superficial femoral vein was competent distal valves in the femoral and popliteal veins may become incompetent resulting in primary valvular incompetence of the deep veins in the lower extremity.

Femoral venous reflux abolished by greater saphenous vein stripping

Preoperative venous duplex scanning has revealed unexpected deep venous incompetence in patients with apparently only varicose veins. Acting on the hypothesis that the deep vein reflux was secondary to deep vein dilation caused by reflux volume, the following was done. Between July 1990 and April 1993, 29 limbs in 21 patients (16 females) were examined by color-flow duplex imaging to determine valve closure by the method of van Bemmelen. Instrumentation included high-resolution ATL-9 venous interrogation using a pneumatic cuff deflation stimulus of reflux in the standing, nonweight-bearing limb. All limbs showed greater saphenous vein reflux. Twenty-nine showed superficial femoral vein reflux and of these three showed popliteal vein reflux. Duplex testing was performed by a certified vascular technologist whose interpretation was blinded as to the results of clinical examination and grading of the severity of venous insufficiency. Surgery was performed on an outpatient basis under general anesthesia using groin-to-knee removal of the greater saphenous vein by the vein inversion technique of Van Der Strict. Stab avulsion of varicose tributary veins was accomplished during the same period of anesthesia. In 27 of 29 limbs with preoperative femoral reflux, that reflux was abolished by greater saphenous stripping. In patients with popliteal reflux both femoral and popliteal reflux was abolished. Improvement of deep venous hemodynamics by ablation of superficial reflux supports the reflux circuit theory of venous overload. Furthermore, preoperative evaluation of venous hemodynamics by duplex scanning appears to provide useful pre- and postoperative information regarding venous insufficiency in individual patients.Presented at the Twelfth Annual Meeting of the Southern California Vascular Surgical Society, Coronado, Calif, September 17–19, 1993.     

Influence of the profunda femoris vein on venous hemodynamics of the limb. Experience from thirty-one deep vein valve reconstructions

Venous valve reconstruction in 31 limbs (28 patients) with chronic deep venous insufficiency is analyzed. The indications for operation were primary or secondary deep valvular incompetence with severe reflux and venous hypertension. Valvuloplasty was performed on a proximal valve of the superficial femoral vein (SFV) in 17 limbs and on a common femoral vein valve in two limbs; transplantation of a valve-bearing segment of the axillary vein was made to the common femoral vein in two limbs, to the SFV in seven limbs, and to the popliteal vein in three limbs. The results of valvuloplasty were satisfactory, with six failures observed during a follow-up period extending to 84 months (mean, 44 months). Eight of 12 valve transplant reconstructions failed within 2 years. Patency and competence of the reconstruction were obtained in 27 limbs at the 6-month postoperative control period. The effects on venous pressure were analyzed regarding the presence or absence of reflux into the profunda femoral vein (PFV) with preoperative retrograde phlebography. The results showed significant reduction of the ambulatory venous pressure (p less than 0.05) and increase in venous recovery time (p less than 0.01) in limbs with PFV competence. In limbs in which the PFV was incompetent the pressure values remained unchanged. These findings suggest that the functional state of the PFV is of great importance to the venous hemodynamics of the limb. This study also indicates that the principle of one-level repair in the SFV seems appropriate in limbs with a competent PFV.     

Effect of external valvuloplasty of the deep vein in the treatment of chronic venous insufficiency of the lower extremity

OBJECTIVE: This study was conducted to verify the efficacy of external valvuloplasty of the femoral vein in the treatment of primary chronic venous insufficiency (PCVI). METHODS: Forty patients with PCVI of the bilateral lower extremities were enrolled at the time of surgical management. All 80 limbs were classified as CEAP C2 to C4, with moderate incompetence of the deep vein. The limbs of each patient were randomized into one of two groups according to the operative method, so that when one limb was randomized to group A, regardless of whether it was the right or left limb, the other limb was assigned to group B. In group A, external valvuloplasty of the femoral vein was combined with surgery of the superficial venous system; in group B, surgery of the superficial venous system alone was performed. The therapeutic effects between the limbs in groups A and B were compared by color duplex scanning, a color Doppler velocity profile, air plethysmography (APG), and a CEAP severity score at 1 month, 1 year, and 3 years postoperatively. RESULTS: Within each group of limbs, no significant differences were found in the average operative time within each group of limbs. The varicose veins resolved, there were no deep vein thromboses, and the wounds healed well postoperatively in all cases. Leg heaviness was relieved completely in 90% of group A limbs (36/40) and 55% of group B limbs (22/40). Venous valve competence was achieved in 100%, 98.1%, and 90.9% of group A limbs at 1 month, 1 year, and 3 years postoperatively, respectively. The amount of venous reflux, APG indices, and CEAP severity scores were not significantly different between the two groups preoperatively (P > .05). The amount of venous reflux, reflux indices, CEAP severity scores, and muscle pumping indices improved markedly in group A limbs postoperatively compared with group B limbs (P < .01); muscle pumping indices did not improve significantly in group B limbs postoperatively (P > .05). There were significant differences in the amount of venous reflux, reflux indices, and CEAP severity scores between group A and B limbs at 1 month and 1 year postoperatively (P < .01). There were significant differences in all parameters assessed between group A and B limbs 3 years postoperatively (P < .05). CONCLUSIONS: External valvuloplasty of the femoral vein combined with surgical repair of the superficial venous system improved the hemodynamic status of the lower limbs, restored valvular function more effectively, and achieved better outcomes than surgical repair of the superficial venous system alone.

下肢深静脉顺行造影在下肢静脉曲张病因诊断中的应用价值

背景与目的:下肢静脉曲张是外周静脉病变的常见临床表现,可由下肢静脉反流性疾病、下肢静脉回流障碍性疾病、静脉畸形等多种疾病所致;不同病因导致的下肢静脉曲张其治疗原则也不尽相同。临床中常出现关于下肢静脉曲张的误诊误治,故明确其病因至关重要。目前下肢静脉造影仍是诊断下肢静脉病变的金标准,可提供完整的下肢静脉系统影像,为明确诊断及选择合适的治疗方案提供可靠依据。本研究总结江苏常州地区以下肢静脉曲张为主要临床症状的患者的下肢深静脉顺行造影结果,探讨造影在下肢静脉疾病中的意义,并分析该地区引起下肢静脉曲张的主要病因。方法:使用数字减影血管造影(DSA)技术,对苏州大学附属第三医院血管外科2013年6月—2019年3月收治的3 012例(3 420条肢体)下肢静脉曲张患者行下肢深静脉顺行造影,观察患肢踝部至盆腔段深静脉形态、通畅度,以及患者做Valsalva动作时造影剂的反流情况,对患者静脉曲张的病因进行分析和分类。结果:3 420条肢体中,原发性下肢深静脉瓣膜功能不全1 395条(40.79%),单纯浅静脉曲张1 052条(30.76%),髂静脉受压综合征569条(16.64%),下肢深静脉血栓后综合征328条(9.59%),其他(双股静脉畸形、腘静脉瘤、深静脉瘤样扩张、先天性静脉曲张骨肥大综合征、布加综合征、盆腔肿瘤等)76条(2.22%)。结论:常州地区下肢静脉曲张患者的病因以下肢深静脉瓣膜功能不全、单纯浅静脉曲张及髂静脉受压为主。对于下肢静脉曲张病变,需明确病因才能制定合理的治疗方案;下肢深静脉顺行造影是明确下肢静脉曲张病因的可靠方法,并能检出腘静脉瘤、布加综合征等少见疾病,可有效避免误诊误治;其在下肢静脉病变中有重要的应用价值,可作为下肢静脉曲张疾病的常规检查方法。
