This study was conducted to identify specific abnormalities using the results from air plethysmography in legs with lymphedema. A routine air plethysmography exercise protocol was performed in 31 patients with unilateral leg lymphedema, and the results were compared with those of 53 patients with unilateral great saphenous vein reflux and 15 normal subjects. The venous filling index in legs with lymphedema (2.1 ± 1.2 mL/sec) was smaller than in legs with great saphenous vein reflux (6.4 ± 4.1 mL/sec, p < 0.05), but was not different from that in normal legs (1.9 ± 1.2 mL/sec). The ejection fraction was similar in all groups. The residual volume fraction in legs with lymphedema (35 ± 32%) was larger than that in normal subjects (13 ± 23%, p < 0.05), but was not significantly different from that in the contralateral leg of the lymphedema patients (32 ± 27%). In conclusion, we found no specific air plethysmography findings in uncomplicated lymphedema.

Objective Analyse venous haemodynamics in healthy primigravidae during pregnancy and in the postpartum. Methods Cohort with primigravidae evaluated in the three trimesters of pregnancy and postpartum. Duplex evaluated venous diameters and reflux; air plethysmography evaluated venous filling index, ejection fraction, residual volume fraction and outflow fraction in both limbs. Results During pregnancy, diameters increased in bilateral common femoral and right infravalvar great saphenous, but returned to first trimester values after delivery. Reflux developed in one woman (5%) in the second trimester and in two more women (15%) in the third trimester. No reflux was detected in postpartum. Bilateral venous filling index was higher during pregnancy. Bilateral ejection fraction and residual volume fraction did not change. Bilateral outflow fraction increased progressively. The right limb outflow fraction in left lateral decubitus was similar. All changes returned to first trimester values after delivery. Conclusions Healthy primigravidae presented changes in lower limbs’ veins during pregnancy: diameters in bilateral common femoral and infravalvar great saphenous veins increased; new reflux was developed in 15% of women, but there was no venous hypertension. Calf muscular pump function did not change. All changes returned to first trimester values after delivery.

SummaryA modification of the fibrin slide method of Todd permitting a semiquantitative estimation of the fibrinolytic activity in tissue sections is described. By means of this technique, the authors have studied the fibrinolytic activity of the great saphenous vein and of superficial veins of the arm and leg in patients suffering from varices and in normal subjects. It was found that:1. Fibrinolytic activity is localized, in these vessels, mainly to the vasa vasorum of the adventitia. The media is moderately active. Intimal cells are active only when detached.2. The great saphenous vein is more active above than below the knee.3. The veins of the arm are definitely more active than the veins of the leg.4. The activator of plasminogen demonstrated in the sections by the fibrin slide method is a fairly stable enzyme still active after exposure to 60° C and resistent to moderate variations of pH.

Objective Iliac vein stenting has been an evolving treatment option in the management of CVI secondary to iliac vein obstruction. Historically, treatment of CVI has been focused on the elimination of saphenous vein disease; however, the effect of reduction of iliac vein obstruction on superficial venous reflux remains largely unknown. This study aimed to identify the effect of iliac vein stenting on saphenous vein reflux. Methods In this retrospective study spanning course of five years, we performed 2681 venograms with venoplasties and stenting of the iliac veins. Pre-operative and post-operative venous mapping was performed via duplex ultrasonography. Patients who received any lower extremity vascular intervention between “pre-” and “post-stenting” duplex ultrasonography examination, other than iliac vein stenting, were excluded from analysis. Results One thousand six hundred forty-five patients, of which 63.2% were female, underwent iliac vein stenting; 1033 patients received bilateral intervention, whereas 356 and 259 patients received unilateral left and right stenting, respectively. The average age of the patient cohort was 66 (range 22–100; SD ± 13.9). The distribution CEAP scores of each limb at the time of intervention were: C2 (1%), C3 (25%), C4 (51%), C5 (5%), and C6 (18%). Bilateral iliac vein stenting significantly reduced reflux in the bilateral great saphenous and small saphenous veins by 363.8 ms ( p < 0.0001) and 345.4 ms ( p < 0.0002), respectively, but had no effect on ASV reflux. Unilateral stenting did not produce significant reductions in reflux, besides an average reduction of 573.2 ms ( p = 0.004) in the left great saphenous vein. Conclusion Bilateral iliac vein stenting decreased great saphenous vein and small saphenous vein reflux. Unilateral stenting did not demonstrate a significant reduction in saphenous reflux. Bilateral reduction in stenosis of the iliac veins may influence superficial venous reflux.

Various treatment methods are available for the treatment of varicose veins, and there has been a recent surge in the usage of cyanoacrylate glue for treating varicose veins. Purpose To investigate the technical possibility, efficiency and safety of cyanoacrylate adhesive embolization and sclerotherapy using commonly available n-butyl cyanoacrylate glue for the treatment of primary varicose veins due to great saphenous vein reflux with or without incompetent perforators. Materials and Methods One hundred forty-five limbs of 124 patients with varicose veins due to great saphenous vein reflux were subjected to cyanoacrylate adhesive embolization and sclerotherapy – adhesive embolization of great saphenous vein in the thigh and perforators using cyanoacrylate followed by sclerotherapy of any residual varicose veins in the leg. Procedural success, venous closure rates and clinical improvement were assessed. Follow-up for 1, 3, 6, 9 and 12 months was obtained. Results Technical success rate was 100%. Saphenous vein closure rate was 96.5% at one year. There was no femoral venous extension of cyanoacrylate in any of the patients. Posterior tibial vein extension of cyanoacrylate was seen in three patients (2.6%) without untoward clinical effect.Significant improvement was found in venous clinical severity score (VCSS) from a baseline mean of 7.98 ± 4.42 to 4.74 ± 3, 1.36 ± 1.65 and 0.79 ± 1.19 at 1, 6 and 12 months’ follow-up. Ulcer healing rate was 100%. Conclusion Cyanoacrylate adhesive embolization and sclerotherapy for the treatment of primary varicose veins is efficacious and can be performed as an outpatient procedure, but has a guarded safety profile due to its propensity to cause deep venous occlusion if not handled carefully.

Objective To describe the anatomy of the lymph node venous networks of the groin and their assessment by ultrasonography. Material and methods Anatomical dissection of 400 limbs in 200 fresh cadavers following latex injection as well as analysis of 100 CT venograms. Routine ultrasound examinations were done in patients with chronic venous disease. Results Lymph node venous networks were found in either normal subjects or chronic venous disease patients with no history of operation. These networks have three main characteristics: they cross the nodes, are connected to the femoral vein by direct perforators, and join the great saphenous vein and/or anterior accessory great saphenous vein. After groin surgery, lymph node venous networks are commonly seen as a dilated and refluxing network with a dystrophic aspect. We found dilated lymph node venous networks in about 15% of the dissected cadavers. Conclusion It is likely that lymph node venous networks represent remodeling and dystrophic changes of a normal pre-existing network rather than neovessels related to angiogenic factors that occur as a result of an inflammatory response to surgery. The so-called neovascularization after surgery could, in a number of cases, actually be the onset of dystrophic lymph node venous networks. Lymph node venous networks are an ever-present anatomical finding in the groin area. Their dilatation as well as the presence of reflux should be ruled out by US examination of the venous system as they represent a contraindication to a groin approach, particularly in recurrent varicose veins after surgery patients. A refluxing lymph node venous network should be treated by echo-guided foam injection.
