Prevention of recurrent deep venous thrombosis with indobufen. A 3-year follow-up study using color duplex scanning.

After an episode of deep venous thrombosis (DVT) 123 patients were randomized into two groups: one was prophylactically treated with indobufen (60 patients), an oral antiplatelet agent, and one had no treatment (63) and acted as a control group. They were followed up for three years and scanned with color duplex scanning (CDS) every three months and any time that signs and symptoms suggested a new episode. In patients receiving indobufen the incidence of thrombosis was 5% in three years while it was significantly higher (46%) in the control group. Also 62% of the new episodes in the control group were asymptomatic (33.3% in the treated group). Results suggest that recurrent DVT is common, often asymptomatic, and confused with sequelae of the initial episode. The prophylaxis with indobufen is an effective measure in preventing recurrent thrombosis and avoiding the progressive deterioration of the deep venous system observed after deep venous thrombosis.

Treatment of acute superficial thrombosis and follow-up by computerized thermography.

Superficial vein thrombosis (SVT) is a common complication of varicose veins. Treatment may be surgical by removal of the superficial clots under local anesthetic or medical in association with elastic compression and mobilization. In this study 83 patients with SVT were randomised in treatments groups: A--superficial thrombectomy and elastic compression (EC); B--Ca Heparin (0.5 mgs b.i.b.) + EC; C--Venoruton (1 g, t.i.d.) + EC; D--Venoruton (1 g, t.i.d.) after superficial thrombectomy + EC; E--elastic compression. All treatments were applied for 8 weeks. The evolution of SVT was studied by a system, based on thermography, which analyse by a computerized system the variation of the hyperthermic areas (HA) on thermograms. This was associated with subjective and objective clinical evaluation. Results indicate a decrease of HA in all groups but patients treated with superficial thrombectomy show a significantly (p, 0.05) greater and faster reduction of HA. The reduction of HA produced by Venoruton was also significantly greater (p less than 0.05) than that observed in patients treated by Ca Heparin or elastic compression and it determined also a faster and greater (p less than 0.05) decrease of HA after thrombectomy. These results were confirmed by clinical observations. In conclusion results from this study indicate a positive effect of Venoruton in SVT in determining a faster decrease of hyperthermic areas probably by decreasing local inflammation.

[Chronic treatment of vascular diseases with indobufen].

The effects of chronic treatment with indobufen, an inhibitor of platelet aggregation, was studied in a group of 1428 patients with vascular problems treated in a period of about 6 years in our Units. Venous problems were the major vascular problem in 313 patients, peripheral vascular diseases in 553 and cerebrovascular problems in 562. In patients with venous problems the range of the treatment period in different groups of patients varied from 2 to 42 months. The range was from 1 to 48 months in the group of patients with peripheral vascular diseases and from 2 to 48 in patients with cerebrovascular diseases. An analogic score was used to evaluate the efficacy of indobufen, which was also compared for the occurrence of side-effects with ASA (acetylsalicylic acid) and dipyridamole. Results obtained in this large, chronic open study confirmed the efficacy of indobufen in preventing (or reducing the occurrence) of vascular problems which was significantly greater than that observed with the other two drugs used for comparison. Indobufen also resulted in a lower incidence of side-effects (particularly gastrointestinal disorders) and it was better tolerated than both dipyridamole and ASA.

[Venoruton and capillary permeability].

A new system to evaluate capillary permeability, the vacuum suction chamber (VSC) device, was used to assess the effects of Venoruton in patients with venous hypertension. A temporary, superficial skin lesion (wheal) was produced with the VSC device by negative pressure (30 mmHg) applied for 10 minutes on the internal, perimalleolar region. Wheals disappear in less than 60 minutes in normals while in patients with venous hypertension the wheal is more persistent, requiring a significantly longer time to disappear. This new technique was used in association with laser-Doppler flowmetry to evaluate the efficacy of Venoruton (1000 mgs t.i.d.) administered for 2 weeks on venous hypertension. Results indicate a positive effect of Venoruton in reducing the abnormally increased capillary permeability in venous hypertension and are proportional to the changes observed in signs and symptoms after treatment.

[Surgical treatment of obesity].

Morbid obesity is a disease of modern society. Surgery is indicated when there is no endocrinopathy, medical treatment failed and Body Mass index (W/H2) is more than 40 (III degree obesity of Garrow). Many different methods were suggested in connection with the type of obesity, the associated diseases and the psychical state of the patient. Jejuno-ileal by-pass intend to produce a generic malabsorption syndrome. Personal experience is however good, possibly due to the blind loop jejunostomy that we always prepare as a conclusion of the operation and which gives an excellent support for the early post-operative time.

Foam-sclerotherapy, surgery, sclerotherapy, and combined treatment for varicose veins: a 10-year, prospective, randomized, controlled, trial (VEDICO trial).

The study compared, by a prospective, randomized method, 6 treatment options: A: Sclerotherapy; B: High-dose sclerotherapy; C: Multiple ligations; D: Stab avulsion; E: Foam-sclerotherapy; F: Surgery (ligation) followed by sclerotherapy. Results were analyzed 10 years after inclusion and initial treatment. Endpoints of the study were variations in ambulatory venous pressure (AVP), refilling time (RT), presence of duplex-reflux, and number of recurrent or new incompetent venous sites. The number of patients, limbs, and treated venous segments were comparable in the 6 treatment groups, also comparable for age and sex distribution. The occurrence of new varicose veins at 5 years varied from 34% for group F (surgery + sclero) and ligation (C) to 44% for the foam + sclero group (E) and 48% for group A (dose 1 sclero). At 10 years the occurrence of new veins varied from 37% in F to 56% in A. At inclusion AVP was comparable in the different groups. At 10 years the decrease in AVP and the increase in RT (indicating decrease in reflux), was generally comparable in the different groups. Also at 10 years the number of new points of major incompetence was comparable in all treatment groups. These results indicate that, when correctly performed, all treatments may be similarly effective. "Standard," low-dose sclerotherapy appears to be less effective than high-dose sclero and foam-sclerotherapy which may obtain, in selected subjects, results comparable to surgery.

Prevention of venous thrombosis in long-haul flights with Flite Tabs: the LONFLIT-FLITE randomized, controlled trial.

The aim of this study was to evaluate the development of edema, and superficial and deep vein thrombosis (DVT) prophylaxis with an oral profibrinolytic agent (Flite Tabs, 150 mg pinokinase, Aidan, Tempe, AZ, USA) in long-haul flights (7-8 hours), in high-risk subjects. A group of 300 subjects was included; 76 were excluded for several problems including concomitant treatments; 204 were randomized into 2 groups (active treatment or placebo) to evaluate the effects of prophylaxis with Flite Tabs. An exercise program was used in both groups. The femoral, popliteal, tibial, and superficial veins were scanned with ultrasound before and within 90 minutes after flights. Of the included subjects, 92 of 103 controls and 94 of 101 treated subjects completed the study. Dropouts were due to connection problems. Age, gender, and risk distribution were comparable in the groups. In the treatment group, no DVT was observed. In the control group, 5 subjects (5.4%) had a DVT and there were 2 superficial thromboses (7 events in 92 subjects; 7.6%). At inclusion, edema was comparable in the 2 groups. After flights there was an increase in score in controls (+12%) in comparison with a decrease (-15%) in the Flite Tabs group (the difference in variation was statistically significant). Intention-to-treat analysis for thrombotic events shows 18 failures in controls (11 lost to follow-up + 7 thrombotic events) of 92 subjects (19.6%) in comparison with 7 failures (of 94 subjects, equivalent to 7.4%) in the treatment group (p < 0.05). Events were asymptomatic. In conclusion, Flite Tabs were effective in reducing thrombotic events and in controlling edema in high-risk subjects in long flights.

Prevention of recurrent deep venous thrombosis with sulodexide: the SanVal registry.

The aim of this study was to evaluate the prevention of recurrent deep vein thrombosis (R-DVT) with an oral antithrombotic agent (sulodexide) in moderate to high-risk subjects. A group of 405 patients was included into the multicenter registry. Both compression and an exercise program were used as well as a risk-factors control plan. After diagnosis of DVT, patients were treated with oral anticoagulants for 6 months. At the end of this period a coagulation study was made and patients started treatment with oral sulodexide capsules for a period of 24 months. The femoral, popliteal, tibial, and superficial veins were scanned with high-resolution ultrasound at inclusion;scans were repeated at 6, 12, 18, and 24 months. Of the 405 subjects included into the registry 178 in the control group (mean age 52.2; SD 11; M:F=90:88) and 189 in the treatment group (mean age 53.2; SD 10.3; M:F=93:96) completed the analysis period of 24 months. At 6 and 12 months the incidence of R-DVT was lower (p<0.05) in the treatment group. At 24 months the global incidence of R-DVT was 17.9% in the control group and 7.4% in the sulodexide group (p<0.05), 2.42 times lower than in controls. The 2 groups were comparable for age and sex distribution and for the localization of the thrombi at inclusion. Also the 2 groups of dropouts were comparable. In the control group there were 32 recurrent DVTs and 24 subjects lost to follow-up (total of 56) of 202 included subjects (27.7%) in comparison with 28 failures (14 recurrent DVTs and 14 lost subjects) of 203 subjects (13.8%) in the treatment group. This difference was statistically significant. In this analysis the incidence of DVT in controls was 2.07 times higher than in the treatment group subjects. In conclusion sulodexide was effective in reducing recurrent thrombotic events in high-risk subjects.
