This paper is the review of the Consensus Document on Intermittent Claudication of the Central European Vascular Forum (CEVF), published in 2008, and and shared with the North Africa and Middle East ...Chapter of International Union of Angiology and the Mediterranean League of Angiology and Vascular Surgery. The Document presents suggestions for general practitioners and vascular specialists for more precise and appropriate management of PAD, particularly of intermittent claudication, and underlines the investigations that should be required by GPs and what the GP should expect from the vascular specialist (angiologist, vascular surgeon). The idea of the Faculty is to produce a short document, which is an easy reference in daily clinical practice, both for the GPs and vascular specialists.
Multifocal atherosclerotic disease or multifocal ischemic pathology (MAD) is an issue gaining a lot of attention by clinicians in recent years, due to its high impact on the morbidity and mortality ...of vascular patients. The coexistence of coronary artery disease (CAD), peripheral arterial disease (PAD) and carotid disease (CS) is being investigated in this study.
The study included 556 consecutive inpatients who were admitted to the Nicosia General Hospital in Cyprus for carotid endarterectomy, peripheral arterial reconstruction or coronary artery bypass. All patients were subjected to color duplex examination of the carotid vessels and to lower extremity Doppler study. Cardiac risk screening was performed on patients with PAD and CS. Comorbidity was evaluated by using the Cumulative Illness Rating Scale (CIRS).
The prevalence of MAD in atherosclerotic patients was found very high (60.3%). The most frequent comorbidity was the coexistence of PAD and CAD (41.8%). The comorbidity burden of MAD patients, in comparison to that of patients with unifocal atherosclerotic disease, was evaluated to conclude that the burden in the first group (MAD) is significantly higher, not only in relation to the number of clinically relevant diseases that co-exist, but also to the severity of these diseases. Furthermore, functional status is negatively affected by the existence of multifocal ischemic pathology.
The high prevalence of MAD suggests the necessity of developing a systematic screening approach in the everyday practice. Apart from cardiovascular problems, other diseases affect the clinical situation of these patients. Therefore, it is important to investigate these problems pre- and postoperatively.

The possible healing effect of deferoxamine and pentoxifylline on persisting lower limb ulcers was studied in 51 patients with thalassemia major. The results indicated that the regular use of ...deferoxamine at an intravenous dose of 20 mg/kg did not affect the healing progress and the recurrence rate of these ulcers significantly. On the contrary, the oral administration of pentoxifylline at a dose of 1,200 mg daily during the ulcer's healing time and at a low long-term maintenance dose of 400 mg daily during the ulcer-free intervals improved their healing ability impressively and diminished their recurrence rate significantly.
The effect of continuous i.v. infusion of pentoxifylline, administering 1,200 mg/24 hours through 15 days, was studied in 22 patients (19 m, 3 f) with arteriographically confirmed extensive occlusion ...in the femoro-popliteal segment, associated with marked intermittent claudication and rest pain of varying severity. The following parameters were used for the verification of the therapeutic response: Flow resistance factor (RF), pressure indices at rest (RPI) and after exercise (PPI) and recovery time (RT) assessed by means of ultrasonic Doppler technique; muscle and skin blood flow at rest and after exercise using 99m Technetium Clearance Technique (TC); toe skin temperature (TST) by electric thermometer; painfree walking distance (WD) assessed on treadmill (horizontal, 4 km/h); rest pain (RP) was assessed by a 4-step-relief-scale. There was an overall good response to treatment, the studied parameters showing the following changes: RF improved in 12/17 patients (= 70%); RT decreased in 14/22 patients (= 63%) RPI and PPI showed no change; TC (muscle) increased after exercise in 17/22 patients (= 77%); TC (skin) increased after exercise in 20/22 patients (= 90%); WD increased on average by 80% (from 115 m to 206 m); TS increased in 16 limbs; RP showed an overall relief. The results of this study indicate that the continuous infusion of pentoxifylline is safe and effective in improving the condition of patients with severe peripheral vascular disease.
The effect of oral pentoxifylline, administered 1,200 mg/day (400 mg slow-release tablets tid) through six weeks, was studied in 10 patients with established deep venous incompetence and persisting ...venous ulcers. The following parameters were used for verification of the therapeutic result: venous patency (VP) and valvular competence (VC) assessed by means of Doppler ultrasound; venous refilling time (VRT) assessed by photoplethysmography; skin blood flow (SBF) at rest and after tiptoeing exercise, as well as skin perfusion pressure (SPP), both assessed by means of 99mtechnetium clearance technique. Finally, photo documentation of the tissue lesion was obtained, using a two-dimensional (max and min diameter = Dmax, Dmin) metered scale photo. There was an overall good response to the treatment, the studied parameters showing the following changes: VP and VC remained unchanged; VRT improved in 8 patients, SBF increased in 10; SPP slightly improved in 5; and Dmax and Dmin in all 10 patients. Removal or substantial diminution of the ulcers was obtained in 8 patients. These findings indicate that oral administration of pentoxifylline over a period of six weeks supports the conservative treatment and improves considerably the condition of patients with persisting venous ulcers.
The aim of this study was to understand the possible mechanisms by which deep venous insufficiency and venous hypertension are associated with trophic skin changes and ulceration and to explain the ...therapeutic effect of Pentoxifylline in patients with leg ulcers due to deep venous incompetence. Twenty patients were included in this pilot study. They were graded into two groups: group 1, included 10 patients (5 F and 5 M) with deep venous incompetence and normal arteries; group 2, included 10 patients (1 F and 9 M) with deep venous incompetence and moderate arterial disease. Skin and muscle biopsies were carried out before and after the oral administration of 1,200 mg of Pentoxifylline daily (400 mg t.d.s). The following parameters were investigated by means of light microscopy and immunofluorescence tests: engorgement of venous stroma; decrease of intimal elastica; hyaline degeneration; floccular degeneration; pericapillary fibrin deposits and fibrin degradation products; inflammation and fat necrosis; myofibril degeneration; fibrous scar; regeneration and reconstitution of muscle fibres. The results indicated that local inflammation at the ulcer's area cause accumulation of white blood cells in the capillaries and the interstitial fluid, where there is also accumulation of fibrinogen. These changes may lead to chronic tissue ischaemia and ulceration. The known favourable effect of Pentoxifylline on red cells and leucocyte function as well as its lowering effect on plasma fibrinogen level, may be responsible for the observed therapeutic effect of Pentoxifylline on venous leg ulcers.
