Objective: To study the anatomical distribution of chronic venous insufficiency (CVI) in a Chinese population by means of duplex scanning. Procedures: A total of 582 limbs in 291 patients with primary venous insufficiency were classified clinically into three different groups according to SVS/ISCVS criteria and evaluated prospectively with duplex scanning. Results: One hundred and thirty-one limbs were classified into group I (CEAP clinical class 0), 291 into group II (CEAP clinical classes 1 and 2) and 160 into group III (CEAP clinical classes 3–6). Mixed deep and superficial venous incompetence was found in 70% and 83% of limbs in groups II and III, respectively. Reflux was also demonstrated in 73% of group I limbs. Conclusions: Most of our patients had mixed deep and superficial venous incompetence. The prevalence of deep venous incompetence in this population, in which deep vein thrombosis is rare, suggests a pattern of venous incompetence other than postphlebitic deep vein valvular dysfunction. The prevalence of reflux in the asymptomatic contralateral limbs implies a bilateral predisposition to venous reflux and thus a possible developmental origin of CVI.

SummaryThe clinical importance of asymptomatic proximal and distal deep vein thrombosis (DVT) remains uncertain and controversial. The aim of this retrospective,post-hoc analysis was to examine mortality and risk factors for development of proximal DVT in hospitalized patients with acute medical illness who were recruited into a randomized, prospective clinical trial of thromboprophylaxis with dalteparin (PREVENT).We analyzed 1738 patients who had not sustained a symptomatic venous thromboembolic event by Day 21 and who had a complete compression ultrasound of the proximal and distal leg veins on Day 21. We examined the 90-day mortality rates in patients with asymptomatic proximal DVT (Group I, N = 80), asymptomatic distal DVT (Group II, N = 118) or no DVT (Group III, N = 1540).The 90-day mortality rates were 13.75%, 3.39%, and 1.92% for Groups I–III, respectively. The difference in mortality between Group I and Group III was significant (hazard ratio 7.63, 95% CI = 3.8–15.3;p < 0.0001),whereas the difference between Groups II and III did not reach significance (hazard ratio 1.36, 95% CI = 0.41–4.45).The association of asymptomatic proximal DVT with increased mortality remained highly significant after adjusting for differences in baseline demographics and clinical variables. Risk factors significantly associated with the development of proximal DVT included advanced age (p = 0.0005), prior DVT (p = 0.001), and varicose veins (p = 0.04). In conclusion, the high mortality rate in patients with asymptomatic proximal DVT underscores its clinical relevance and supports targeting of asymptomatic proximal DVT as an appropriate endpoint in clinical trials of thromboprophylaxis.

SummaryAim: Authors performed a retrospective analysis of causes of recurrent varicose veins following surgery. Methods: They evaluated 89 patients (65 women and 24 men, mean age 49.7 years). All patients previously underwent same surgical procedures (long saphenous vein stripping with/without local multiple avulsions). For the purpose of the study, colour/duplex examinations were applied (Siemens Sonoline Elegra unit). Results: Depending on the type and area of recurrent varicose veins, patients were classified into 4 groups. Group I – 22 patients (persistence of varicose tributaries of LSV in thigh or thigh perforator). Group II – 27 patients (recurrence along the LSV in the calf). Group III – 26 patients (recurrence due to left incompetent short saphenous vein). Group IV – 14 patients (isolated incompetent perforators). Authors conclude, that colour-coded duplex scanning is currently a method of choice in the diagnosis of recurrent varicose veins. High incidence of recurrence due to short saphenous vein incompetence should draw particular attention to this vein in the preoperative assessment of venous system. Recurrence of varicose veins at thigh level is not caused by deep vein insufficiency, but is related to inadequate vein surgery or might be linked to the problem of neovascularisation in this area.

Two patients with angio-access for haemodialysis in whom the main venous outflow tract was thrombosed, developed severe chronic venous insufficiency (CVI) of the upper limb after a short period; one case developing a stasis ulcer of the cubital fossa. The angio-accesses were still functioning when the diagnosis was made. Treatment by surgery resulted in a dramatic regression of clinical signs of chronic venous insufficiency. CVI of the upper limb has not previously been described. CVI is a frequent and known complication after deep vein thrombosis (DVT) of the lower limbs, but never appears after DVT of the upper limbs. We describe two cases of upper limb CVI which developed as a complication of angio-access for haemodialysis treatment, and their successful treatment by surgery.

150 patients over 40 years old undergoing major abdominal surgery were divided into 3 groups:1/ group I - receiving a single injection of long acting anabolic steroid /nandrolone phenylpropio-nate, 50 mg intramusculary/ a day prior to surgery 2/ gropup II - receiving the same dose of anabolic steroid plus a single dose of heparin /800 U/kg of body weight/ intrapulmonary a day prior to surgery 3/ group III - receiving only a single dose of heparin /800 U/kg of body weight/ intrapulmonary a day prior to surgery.The deep vein thrombosis /DVT/ was detected using the 125 I-fibrinogen test. The occurence of DVT was:in group I - 14%in group II - 4%in group III - 8%There were no detectable haemorrhagic complications in patients of group I and III, in 6% of patients of group II a sgliht increase of intraoperative bleeding and/or wound hematoma appeared.We conclude that prophylaxis of DVT in the postoperative period with the single dose of anabolic steroid and intrapulmonary heparin is an effective, safe and easy to handle procedure.

Post-thrombotic syndrome (PTS) is one of the most significant complications that develops in patients after deep vein thrombosis. Patients with PTS have persistent and often worsening chronic venous insufficiency which can lead to permanent impairment of the affected organ, tissue or limb. Despite their importance, the issues of diagnosis and prevention of PTS in children are understudied in Russia. This paper is based on the analysis of recently published data and presents the current state of affairs regarding PTS in pediatrics.

Heparin Prophylaxis

162 elective hip operation patients were randomly allocated to: Group I: 5 000 U heparin injected s.c. 10 and 2 hours pre-operatively, then 8 hourly; Group II: heparin as above plus dextran 40 on three days; Group III: heparin as in group I combined with dihydroergotamine (DHE). The 125-I-fibrinogen test was routinely used for diagnosis of deep vein thrombosis (DVT), when positive, phlebography was performed. DVT occurred in 8/55 patients in group I, in 9/54 in group II and in 2/53 in group III. (Chi-square test: I vs. III p = 0.054; II vs. III p = 0.028) . Pulmonary embolism (confirmed at autopsy) occurred in one patient in both group I and II.In the three groups, the intra-operative transfusions, wound blood loss at the pre- and post-operative haematocrit did not differ.Platelet aggregation was only significantly lowered in group II.Heparin/DHE were most effective in preventing thromboemboli, dextran infusions did not improve heparin prophylaxis.Peridural anaesthesia performed in 83 - 87% of patients in all groups led to no complications following pre-operative heparin.

Patients with spinal cord injury (SCI) are at an increased risk of deep vein thrombosis (DVT). This study aims at assessing usefulness of D-dimer and compressive Doppler ultrasonography (CDUS) for detecting DVT in patients undergoing rehabilitation at various time-points post-SCI. One-hundred forty-five patients were divided into three groups based on time elapsed since SCI: I (≥3 weeks to 3 months), II (≥3 to 6 months), and III (≥6 months). On admission, D-dimer plasma level measurement and CDUS of the lower limbs venous system were performed. DVT was diagnosed using CDUS in 15 patients (10.3% of entire group), more frequently in group I (22.2% of group) and II (11.7%) compared to group III (1.5%). Most DVT patients received thromboprophylaxis (80%) and were asymptomatic or mildly symptomatic (60%). Median D-dimer was elevated in patients with DVT from all groups, and also patients without DVT from groups I and II, but not group III. D-dimers were higher in patients with DVT than without DVT in the entire group (p = 0.001) and group I (p = 0.02), but not in groups II and III. The risk of DVT in SCI patients undergoing rehabilitation and thromboprophylaxis including asymptomatic or mildly symptomatic cases, is high within 6 months post-injury, and especially within 3 months. Measurement of D-dimer level should be complemented by routine CDUS for detecting DVT within 6 months post-SCI. Over 6 months, the usefulness of D-dimer screening alone is better for DVT detection.

Introduction Lower limb venous disease affects up to one half, and obesity up to one quarter, of the adult population. Many people are therefore affected by, and present to health services for the treatment of both conditions. This article reviews the available evidence of pathophysiological and clinical relationship between obesity and varicose veins, chronic venous insufficiency and ulceration and deep vein thrombosis. Methods A literature search of PubMed and Cochrane libraries was performed in accordance with PRISMA statement from 1946 to 2015, with further article identification from following cited references for articles examining the relationship between obesity and venous disease. Search terms included obesity, overweight, thrombosis, varicose veins, CEAP, chronic venous insufficiency, treatment, endovenous, endothermal, sclerotherapy, bariatric surgery and deep vein thrombosis. Results The proportion of the population suffering from lower limb venous disease and obesity is increasing. Obesity is an important risk factor for all types of lower limb venous disease, and obese patients with lower limb venous disease are more likely to be symptomatic as a result of their lower limb venous disease. The clinical diagnosis, investigation, imaging and treatment of lower limb venous disease in obese people present a number of challenges. The evidence base underpinning medical, surgical and endovenous management of lower limb venous disease in obese people is limited and such treatment may be associated with worse outcomes and increased risks when compared to patients with a normal body mass index. Conclusion Lower limb venous disease and obesity are both increasingly common. As such, phlebologists will be treating ever greater numbers of obese patients with lower limb venous disease, and clinicians in many other specialties are going to be treating a wide range of obesity-related health problems in people with or at risk of lower limb venous disease. Unfortunately, obese people have been specifically excluded from many, if not most, of the pivotal studies. As such, many basic questions remain unanswered and there is an urgent need for research in this challenging and increasingly prevalent patient group.
