The occurrence of the Peregrine's ulcer is scientifically explainable but its miraculous healing in one night cannot be explained by the current scientific knowledge. The long history of fluid mechanics, anatomic and pathophysiologic discoveries led to the better knowledge of hemodynamics in pathophysiology. The last technologies provided strong means to the assessment of venous insufficiency, especially Duplex Ultrasound. Renewed hemodynamic concepts provide a better explanation of the pathophysiology of venous leg ulcers as well as reliable outcomes and less recurrences for varicose veins and ulcers.

Chronic venous insufficiency (CVI) can result in varicose veins or, if severe, may develop skin changes and leg ulcerations. This chapter details the classification and presentation of varicose veins and venous leg ulcers (CEAP classification). It outlines the recommended investigations for CVI such as handheld Doppler scan and venous duplex ultrasound scans. The management of CVI is to improve the venous and lymphatic flow thereby improving the skin oxygen transport through reducing oedema. This can be performed by graduated compression bandages.

Objective: To review the prevalence of and risk factors for varicose veins, chronic venous insufficiency (CVI) and venous leg ulcers. Data sources: MEDLINE was searched for the terms prevalence and varicose veins, chronic venous insufficiency, or venous leg ulcers. Study selection: The extant world literature (1966–1999) with a minimum of an available English abstract was collected. Ninety-nine studies were reviewed. Data extraction: Data were extracted on prevalence of diseases of the veins in the lower limb, age and gender of the subject populations, and other risk factors for those diseases examined by the original researchers. Data synthesis: The two most prominent risk factors for venous disease are increasing age and female gender. Additional risk factors for venous disease with at least some documentation in the literature include dietary patterns, obesity, physical activity, standing occupations, constrictive clothing, connective tissue laxity, and hormonal differences, including pregnancy. Family history is also a prominent risk factor, suggesting a genetic component. Conclusions: Varicose veins are found more commonly in women, and with increased age. The increase with age is linear, suggesting a constant incidence and cumulative prevalence. CVI is also more common in women and increases with age, but data are limited. Venous leg ulcers are much less common than varicose veins or CVI and show less of a female preponderance, but increase exponentially with age, suggesting a true increasing incidence with age.

Aim To review epidemiologic data on progression of venous pathology in varicose veins and from varicose veins towards chronic venous insufficiency. Methods We searched Medline and PubMed for epidemiologic studies concerning progression of venous pathology. Results The data suggest that reflux progression may develop from segmental to multisegmental superficial reflux. In younger age, reflux in tributaries and non-saphenous veins is more frequent. In older age, more saphenous reflux develops and more proximal sites seem to be affected. A high proportion of uncomplicated varicose vein (C2) develops skin changes and chronic venous insufficiency (C3–C6). Significant risk factors for the progression of varicose vein towards venous leg ulcers are skin changes, corona phlebectatica, higher body mass index and popliteal vein reflux. During a 13.4-year follow-up period, 57.8% (4.3%/year) of all chronic venous disease patients showed progression of the disease. Summary Studies on the progression of venous pathology show a high progression rate of chronic venous disease. More follow-up studies are still needed to get better information about the risk of varicose vein patients for progression to venous leg ulcers and to answer the question which patients may benefit from early varicose vein interventions.

Objective: To investigate the incidence of lower limb venous insufficiency in morbidly obese patients. Patients and methods: The study group comprised 125 patients (109 women, 16 men). The median (range) age and body mass index were 35 (19–59) years and 42 (32–68) kg/m2 respectively. Eleven patients had clinical signs of varicose veins or had previously undergone varicose vein surgery. Patients were investigated with duplex ultrasound scanning on the day before surgery. Iliac, femoral, popliteal, and long and short saphenous veins in both legs were studied. Results: A total of 33 patients had abnormal reflux in the superficial veins (>0.5 s). In the deep veins 2 patients had valvular incompetence in the common femoral vein with reflux times of 2 and 0.7 s respectively. At reinvestigation 18 and 24 months after surgery the reflux times were normalised. Conclusion: In this study the incidence of deep venous incompetence in the lower limb in morbidly obese patients is low.

Objective: To describe a practical technique to reliably find and study crural veins by duplex ultrasound scanning. Design: Prospective scanning of patients referred for evaluation of possible chronic deep venous insufficiency. Setting: A non-invasive vascular diagnostic laboratory in Melbourne, Australia. Patients: A study of 1340 legs in 917 consecutive patients referred with primary or recurrent varicose veins, or for evaluation of possible deep venous disease causing aching or swelling in the legs. Interventions: Examination of the crural veins by duplex ultrasound scanning. Main outcome measure: Identification of all three sets of crural veins. Results: Rates for detecting the posterior tibial, anterior tibial and peroneal veins were 97%, 92% and 91% respectively and all three were observed in 91%. If the last 1227 legs studied by colour-Doppler duplex ultrasound are considered, the rates for detection were 98%, 96% and 96% respectively. Conclusion: Examination of the crural veins can be a part of routine duplex ultrasound scanning in patients referred with suspected venous disease.

Design: Case report. Setting: Vascular Surgery Department, Hull Royal Infirmary, UK. Patients: A 79-year-old man with a history of right leg ulcer and pulsatile veins. Investigations and interventions: Clinical examination revealed findings of tricuspid regurgitation. Investigations included duplex scans, CT scan, arteriography and both trans-thoracic and trans-oesophageal echocardio-graphy. These all proved inconclusive. High sapheno-femoral ligation and stripping of long saphenous vein ligation procedure resulted in healing of his ulcers within six months Conclusion: Pulsatile veins in the leg may be due to tricuspid regurgitation or AV malformation. Echocardiogram, duplex scan and angiograms can help to differentiate between the two diagnoses. In this case, the above investigations were misleading and clinical examination here played the key role.

Soft tissue ulceration resulting from chronic venous insufficiency is a common condition that requires standardised long-term therapy, which has been thoroughly established. We report a patient with a five-year history of persistent venous stasis ulcers despite treatment consistent with traditional wound care. Resolution of the ulcers began only upon deviation from conventional therapy. This report considers non-standard treatments in patients with venous ulcers that do not progress.

Ultrasound guided sclerotherapy may be complicated by intra-arterial injections resulting in significant tissue necrosis. Here, we present a 69-year-old man with a history of right small saphenous vein “stripping”, presenting for the treatment of symptomatic lower limb varicose veins. Duplex ultrasound of the right lower limb outlined the pathway of venous incompetence. Despite the history of “stripping”, the small saphenous vein was present but the sapheno-popliteal junction was ligated at the level of the knee crease. No other unusual findings were reported at the time. During ultrasound guided sclerotherapy, subcutaneous vessels of the right posterior calf were noted to be pulsatile on B-mode ultrasound. Treatment was interrupted. Subsequent angiography and sonography showed absence of the right distal popliteal artery. A cluster of subcutaneous vessels of the right medial and posterior calf were found to be arterial collaterals masquerading as varicose veins. Injection sclerotherapy of these vessels would have resulted in significant tissue loss. This case highlights the importance of vigilance at the time of treatment and the invaluable role of ultrasound in guiding endovenous interventions.
