下肢浅静脉曲张研究的新进展：文献综述

1916年,Homans提出可将下肢浅静脉曲张症,按病因的不同分为单纯性和继发性两大类,前者指隐-股静脉瓣功能不全,使血液由深静脉倒流,逐步破坏大隐静脉中所有辦膜,导致下肢浅静脉曲张;后者为下肢深静脉血栓形成后,浅静脉代偿性扩张。对单纯性者,Homans主张作大隐静脉高位结扎加剥脱术的手术治疗。1938年,Linton强调小腿下段交通静脉功能不全与溃疡形成有密切的关系,主张对有溃疡者,都需在小腿部作交通静脉结扎术。这样便形成了沿用至今的经典手术治疗方法。

Clinical and hemodynamical findings in legs with previous surgery of the great saphenous vein: role of the small saphenous vein

AIM: To assess the role of small saphenous vein (SSV) reflux in patients with a long history of varicose disease and previous stripping of the great saphenous vein (GSV). METHODS: Consecutive patients with a history of GSV stripping 5-19 years earlier were enrolled in this prospective clinical study. A total of 101 legs of 75 consecutive patients fulfilled the study criteria: previous stripping of GSV from ankle to groin at least 5 years earlier, no history of thromboembolism and no previous surgery of deep veins or SSV. All patients were studied clinically using standardized classifications: clinical class, clinical disability score (CDS) and venous clinical scoring system (VCSS). Colour flow duplex imaging (CFDI) was used to assess reflux in deep and superficial veins. Details of prior surgery were evaluated. RESULTS: Overall, SSV reflux was noted in 28 (28%) of the legs, recurrent GSV (rGSV) in the thigh in 41 (41%), reflux in tributaries alone in 28 (28%) and a combination of SSV and rGSV reflux in 4 (3%). Segmental deep reflux was measured in 23 (23%) of the legs; the prevalence of deep reflux was significantly higher in complicated than in uncomplicated legs (12% versus 47%; P<0.05). Deep reflux was more frequently associated with SSV reflux than with rGSV reflux (50% versus 22%; P<0.05). The prevalence of SSV with or without deep reflux increased from 17% to 50% (P<0.05) when uncomplicated (C2-3) and complicated (C4-6) legs were compared. A similar increase was not seen in the legs with rGSV (39% versus 44%; P>0.05). SSV reflux without deep reflux was observed in 25% of the legs with complicated (C4-6) disease, whereas the prevalence of SSV reflux was low (9%) in uncomplicated (C2-3) legs. VCSS was higher in the legs with SSV reflux than in those with rGSV reflux. CDS scores tended to be higher in the SSV reflux group than in the legs with rGSV reflux or tributary reflux alone. After exclusion of deep reflux, the results remained at the same level. CONCLUSION: Small saphenous vein (SSV) reflux is common in legs with recurrent varicose veins and previous stripping of the GSV. SSV reflux alone is frequent in complicated legs, and SSV reflux is typically associated with segmental deep reflux. Clinical and hemodynamical findings stress the role of SSV reflux in this selected venous population.     

Graduated compression stockings (20-30 mmHg) do not compress leg veins in the standing position

BACKGROUND: Since graduated compression stockings (GCS) reduce the risk of deep venous thrombosis (DVT) in both hospital and ambulant patients, we checked the compressive efficiency of 20-30 mmHg GCS in the standing position. METHODS: In 30 volunteers (17 normal legs, 13 varicose legs), duplex ultrasound was used to measure the internal diameters of the long saphenous vein, posterior tibial veins, peroneal veins, and soleal veins in the lying and standing position and with and without 20-30 mmHg GCS. RESULTS: Graduated compression stockings effectively compressed both superficial and deep veins in supine individuals but not the superficial or the deep veins when standing. In the varicose leg, the stockings did not compress the long saphenous vein at the mid-calf level even when supine. In the varicose leg the long saphenous vein was constricted at the upper band of the stocking, which might explain why superficial venous thrombosis is more common when compression stockings are worn. CONCLUSIONS: In the standing position, GCS did not compress the deep or superficial veins of the calf.     

Reflux patterns in the ovarian and hypogastric veins in patients with varicose veins and signs of pelvic venous incompetence

Patients with varicose veins who also had clinical and/or duplex ultrasound findings suspicious of pelvic venous incompetence (PVI) underwent selective retrograde catheter phlebography of the pelvic veins. One hundred and one patients (all female, mean age 49.3 years) underwent selective phlebography of the pelvic veins. In 68 cases (67.3%) a varicose vein recurrence after previous stripping of the greater saphenous vein was present, and about half the patients (n=45, 44.6%) were multipara ( > or =2 episodes of childbirth). The presence and extent of any reflux was documented and the ovarian and pelvic veins affected by the reflux were recorded. Retrograde selective phlebography demonstrated a PVI in 75 patients (74.2%). The left ovarian vein and the right hypogastric vein were most frequently affected by reflux (n = 41, 54.6% each). The left hypogastric vein was incompetent in 35 patients (46.6%) and the right ovarian vein in 3 cases (4%). In about half the patients with pelvic venous incompetence, reflux was demonstrated in more than one of the main pelvic veins (n=38, 50.6%). Fifty-one (68%) of the 75 patients with pelvic venous incompetence had varicose vein recurrence after previous stripping of the greater saphenous vein. Extension of the reflux into varicose veins of the groin or lower leg was demonstrated in 44 patients (58.6%). Thirty-nine patients (52%) received treatment for their pelvic venous incompetence (coil embolisation, sclerotherapy or videoscopic ovarian vein ligation). Pelvic venous reflux was present in 75% of our study population. Combined reflux in more than one pelvic vein was common and in about 60% of cases the pelvic reflux was shown to feed varicose veins of the legs. Therefore, typical clinical and/or duplex findings should lead to a strong suspicion of pelvic venous incompetence and reduce the need for selective retrograde catheter phlebography in this selected group of patients.

Deep axial reflux, an important contributor to skin changes or ulcer in chronic venous disease

OBJECTIVE: We undertook this cross-sectional study to investigate the distribution of venous reflux and effect of axial reflux in superficial and deep veins and to determine the clinical value of quantifying peak reverse flow velocity and reflux time in limbs with chronic venous disease. PATIENTS AND METHODS: Four hundred one legs (127 with skin changes, 274 without skin changes) in 272 patients were examined with duplex ultrasound scanning, and peak reverse flow velocity and reflux time were measured. Both parameters were graded on a scale of 0 to 4. The sum of reverse flow scores was calculated from seven venous segments, three in superficial veins (great saphenous vein at saphenofemoral junction, great saphenous vein below knee, small saphenous vein) and four in deep veins (common femoral vein, femoral vein, deep femoral vein, popliteal vein). Axial reflux was defined as reflux in the great saphenous vein above and below the knee or in the femoral vein to the popliteal vein below the knee. Reflux parameters and presence or absence of axial reflux in superficial or deep veins were correlated with prevalence of skin changes or ulcer (CEAP class 4-6). RESULTS: The most common anatomic presentation was incompetence in all three systems (superficial, deep, perforator; 46%) or in superficial or perforator veins (28%). Isolated reflux in one system only was rare (15%; superficial, 28 legs; deep, 14 legs; perforator, 18 legs). Deep venous incompetence was present in 244 legs (61%). If common femoral vein reflux was excluded, prevalence of deep venous incompetence was 52%. The cause, according to findings at duplex ultrasound scanning, was primary in 302 legs (75%) and secondary in 99 legs (25%). Presence of axial deep venous reflux increased significantly with prevalence of skin changes or ulcer (C4-C6; odds ratio [OR], 2.7; 95% confidence interval [CI], 1.56-4.67). Of 110 extremities with incompetent popliteal vein, 81 legs had even femoral vein reflux, with significantly more skin changes or ulcer, compared with 29 legs with popliteal reflux alone (P =.025). Legs with skin changes or ulcer had significantly higher total peak reverse flow velocity (P =.006), but the difference for total reflux time did not reach significance (P =.084) compared with legs without skin changes. In contrast, presence of axial reflux in superficial veins did not increase prevalence of skin changes (OR, 0.73; 95% CI, 0.44-1.2). Incompetent perforator veins were observed as often in patients with no skin changes (C0-C3, 215 of 274, 78%) as in patients with skin changes (C4-C6, 106 of 127, 83%; P =.25). CONCLUSION: Continuous axial deep venous reflux is a major contributor to increased prevalence of skin changes or ulcer in patients with chronic venous disease compared with segmental deep venous reflux above or below the knee only. The total peak reverse flow velocity score is significantly higher in patients with skin changes or ulcer. It is questionable whether peak reverse flow velocity and reflux time can be used to quantify venous reflux; however, if they are used, peak reverse flow velocity seems to reflect venous malfunction more appropriately.     

The profile of leg symptoms, clinical disability and reflux in legs with previously operated varicose disease.

PURPOSE: It is difficult to assess the severity and location of venous insufficiency in legs with recurrent varicose disease. This present purpose was to evaluate the distribution of reflux and the diagnostic role of current classifications in a consecutive series of legs with previously operated varicose disease. METHODS: A total of 90 legs in a cohort of 66 patients were included. The examination comprised CEAP clinical class, clinical disability score (CDS) and leg symptoms. Colour-flow duplex imaging (CFDI) was used to observe reflux in deep and superficial veins. Details of prior surgery were assessed. RESULTS: The site of superficial reflux was at the groin in 58% (recurrent or residive vein trunk or unoperated great saphenous vein), and the rate in the popliteal fossa was 11% (unoperated short saphenous vein). In 58% of the legs presenting superficial reflux at groin level, previous surgery at the saphenofemoral junction was noted. A sensation of pain was observed in 74% of the legs, sensation of oedema in 64%, itching in 26 %, and night cramps in 8%, respectively. Only itching was significantly infrequent in uncomplicated (CEAP C 2-3) legs, and in legs with local reflux was restricted to vein tributaries. Higher CDS (classes 2-3) were significantly more frequent among complicated legs (CEAP clinical class C2-3: 22% versus CEAP clinical class C4-6: 77%; p < 0.005). A similar situation was noted when legs with only local reflux were compared to those with more severe reflux (local reflux: 7% versus severe reflux: 48%; p < 0.005). CONCLUSIONS: Superficial reflux is frequently detected at groin level despite prior surgery. Unstructured evaluation of leg symptoms is not beneficial. Clinical disability scores associate well with the severity of the venous disease.

The surgical anatomy of the superficial and perforating veins of the lower limb.

The superficial venous system was dissected in 60 legs. A possible function is ascribed to the long saphenous vein and an argument against its stripping in varicose veins presented. Abnormality of the long saphenous vein and its association with varicose veins is described. Particular features of the saphenous tributaries are noted and their relevance in varicosity discussed. The perforator system is described, the distinguishing properties of the medial ankle perforators being examined and their anatomical confinement delineated.
