The aim of this study was to evaluate the prevalence and incidence of venous diseases and the role of concomitant/risk factors for varicose veins (VV) or chronic venous insufficiency (CVI). The study was based in San Valentino in Central Italy and was a real whole-population study. The study included 30,000 subjects in eight villages/towns evaluated with clinical assessment and duplex scanning. The global prevalence of VV was 7%; for CVI, the prevalence was 0.86% with 0.48% of ulcers. Incidence (new cases per year) was 0.22% for VV and 0.18% for CVI; 34% of patients with venous disease had never been seen or evaluated. The distribution of VV and CVI in comparison with duplex-detected incompetence (DI) indicates that 12% of subjects had only VV (no DI), 2% had DI but no VV, 7.5% had DI associated with VV, 2% apparent CVI without DI, 3% DI only (without CVI), and 1.6% both CVI and DI. VV associated with DI are rapidly progressive and CVI associated with DI often progresses to ulceration (22% in 6 years). VV without significant DI (3%) and venous dilatation without DI tend to remain at the same stage without progression for a lengthy time. New cases per year appear to have a greater increase in the working population (particularly CVI) possibly as a consequence of trauma during the working period. In older age (>80 years), the incidence of CVI tends to decrease. Ulcers increase in number with age. Only 22% of ulcers can be defined as venous (due to venous hypertension, increased ambulatory venous pressure, shorter refilling time, obstruction and DI). Medical advice for VV or CVI is requested in 164 subjects of 1,000 in the population. In 39 of 1,000, there is a problem but no medical advice is requested and in only 61 of 1,000, the venous problem is real. In VV in 78% of limbs, there is only reflux, in 8% only obstruction, and in 14% both. In CVI, 58% of limbs have reflux, 23% obstruction, and 19% both. In conclusion, VV and CVI are more common with increasing age. The increase with age is linear. There was no important difference between males and females. These results are the basis for future real, whole population studies to evaluate VV and CVI.
Superficial vein thrombosis is characterized by clotting of superficial veins (ie, following direct trauma) with minimal inflammatory components. Superficial thrombophlebitis is a minimally thrombotic process of superficial veins associated with inflammatory changes and/or infection. Treatments generally include analgesics, elastic compression, anti-inflammatory agents, exercise and ambulation, and, in some cases, local or systemic anticoagulants. It is better to avoid bed rest and reduced mobility. Topical analgesia with nonsteroidal, anti-inflammatory creams applied locally to the superficial vein thrombosis/superficial thrombophlebitis area controls symptoms. Hirudoid cream (heparinoid) shortens the duration of signs/symptoms. Locally acting anticoagulants/antithrombotics (Viatromb, Lipohep, spray Na-heparin) have positive effects on pain and on the reduction in thrombus size. Intravenous catheters should be changed every 24 to 48 hours (depending on venous flow and clinical parameters) to prevent superficial vein thrombosis/superficial thrombophlebitis and removed in case of events. Low molecular weight heparin prophylaxis and nitroglycerin patches distal to peripheral lines may reduce the incidence of superficial vein thrombosis/superficial thrombophlebitis in patients with vein catheters. In case of superficial vein thrombosis/superficial thrombophlebitis, vein lines should be removed. In neoplastic diseases and hematological disorders, anticoagulants may be necessary. Exercise reduces pain and the possibility of deep vein thrombosis. Only in cases in which pain is very severe is bed rest necessary. Deep vein thrombosis prophylaxis should be established in patients with reduced mobility. Antibiotics usually do not have a place in superficial vein thrombosis/superficial thrombophlebitis unless there are documented infections. Prevention of superficial vein thrombosis should be considered on the basis of patient's history and clinical evaluation.
Sulodexide administration after DVT appears to be effective in preventing PTS in association with recommended management and a number of recurrent DVTs. Modalities of treatment, dosages, and timing of administration should be explored in more comprehensive and complete studies.
The aim of this international multicenter trial was to evaluate the effects of a new surgical device (Gore External Valve Support-EVS) and technique for external valvuloplasty of the long saphenous vein (LSV). Patients with superficial venous disease and venous hypertension due to pure superficial venous incompetence were randomized into two treatment groups, the first treated with "conventional treatment" (ligation or stripping) and the second with external valvuloplasty with the EVS. Patients with uncomplicated varicose veins within the age range of 35-65 years were included. Incompetence with presence of functional cusps at the saphenofemoral junction (SFJ), with vein dilatation were the main inclusion criteria. The EVS comprised of a GORE-TEX patch material (including a nitinol frame) that is placed around the vein, producing a reduction in the caliber of the vein. Also the vein section becomes elliptical. These combined actions are aimed to reduce incompetence, allowing a better closure of the cusps. The EVS was placed at the SFJ after limited dissection of the vein and ligation of collaterals. The procedure was randomized as an alternative to simple ligation or stripping (according with the procedure commonly used in the center). The associated ligation of distal incompetent veins was allowed. The main outcome measures of the study were evaluated by color-duplex (morphologic findings and evaluation of reflux) and with ambulatory venous pressure (AVP) or air-plethysmography (APG). Main endpoints of the first year of the study and main subject of this report (mainly concerning safety within the first year of follow-up) were considered presence/absence of reflux; patency of the veins; mobility/function of vein cusps; occurrence of thrombosis; tolerability of the device; and increased complexity and operating time needed for the EVS. At 1 year 30 patients had been randomized (14 EVS implanted, 16 controls). Reflux was absent in all EVS patients, all treated veins were patent, and all cusps were mobile. No thrombosis had been observed and the tolerability of the device was very good. The increased complexity required by placing the EVS was limited (5-12 minutes more). In conclusion results of the first year show efficacy and tolerability of the EVS. In selected patients (superficial LSV incompetence, reflux-dilatation, functional SFJ cusps, incompetence mainly due to enlargement of the vein), the EVS could be an effective alternative to "destructive" ligation and/or stripping of the vein. Prolonged follow-up will indicate the clinical potentials of the EVS.
The recent and increased number of scientific reports on venous thrombosis and venous thromboembolism induced by corona- virus, suggests to improve our level of attention because thrombophlebitis could be a clinical manifestation of COVID-19. We need to be aware also of rare varieties of venous thrombosis such as Mondor disease. The comparison between the enigmatic breast discoloration of the Bathsheba painted by Rembrandt and a case of Mondor disease observed in 2020, becomes a cultural game to improve our clinical skills in diagnosing Mondor thrombophlebitis.
