Leg ulcers are some of the most common wounds treated by the NHS. Ulceration is usually classified as being of venous or arterial origin. Arterial ulcers develop because of reduced arterial flow to the leg caused by peripheral arterial disease. Venous leg ulcers, the most common form, develop because of vein incompetence, with valve failure leading to pressure in the veins. Nurses working with patients with oedema find that chronic oedema can cause the limb affected to swell, causing skin to stretch and break and lead to ulceration. This is known as superficial ulceration. This article discusses the causes, assessment and management of these different types of leg ulcer.

Level Of Agreement

Background The objective of this investigation was to determine the level of agreement between a systematic clinical Doppler examination of the foot and ankle and diagnostic peripheral angiography. Methods The described Doppler examination technique attempted to determine the patency, quality, and direction of the flow through the dorsalis pedis artery, posterior tibial artery, terminal branches of the peroneal artery, and vascular arch of the foot. These results were then compared with angiographic distal run-off images as interpreted by a blinded vascular surgeon. Results Levels of agreement with respect to artery patency/quality ranged from 64.0% to 84.0%. Sensitivity ranged from 53.8% to 84.2%, and specificity ranged from 64.7% to 91.7%. Agreement with respect to arterial flow direction ranged from 73.3% to 90.5%. Conclusions We interpret these results to indicate that this comprehensive physical examination technique of the arterial flow to the foot and ankle with a Doppler device might serve as a reasonable initial surrogate to diagnostic angiography in some patients with peripheral arterial disease.

Abstract. Background: Multilevel peripheral arterial disease is frequently observed in patients with intermittent claudication or critical limb ischemia. This report evaluates the efficacy of one-stage hybrid revascularization in patients with multilevel arterial peripheral disease. Patients and methods: A retrospective analysis of a prospective database included all consecutive patients treated by a hybrid approach for a multilevel arterial peripheral disease. The primary outcome was the patency rate at 6 months and 1 year. Secondary outcomes were early and midterm complication rate, limb salvage and mortality rate. Statistical analysis, including a Kaplan-Meier estimate and univariate and multivariate Cox regression analyses were carried out with the primary, primary assisted and secondary patency, comparing the impact of various risk factors in pre- and post-operative treatments. Results: 64 patients were included in the study, with a mean follow-up time of 428 days (range: 4 − 1140). The technical success rate was 100 %. The primary, primary assisted and secondary patency rates at 1 year were 39 %, 66 % and 81 %, respectively. The limb-salvage rate was 94 %. The early mortality rate was 3.1 %. Early and midterm complication rates were 15.4 % and 6.4 %, respectively. The early mortality rate was 3.1 %. Conclusions: The hybrid approach is a major alternative in the treatment of peripheral arterial disease in multilevel disease and comorbid patients, with low complication and mortality rates and a high limb-salvage rate.

Abstract. Increased arterial stiffness results from reduced elasticity of the arterial wall and is an independent predictor for cardiovascular risk. The gold standard for assessment of arterial stiffness is the carotid-femoral pulse wave velocity. Other parameters such as central aortic pulse pressure and aortic augmentation index are indirect, surrogate markers of arterial stiffness, but provide additional information on the characteristics of wave reflection. Peripheral arterial disease (PAD) is characterised by its association with systolic hypertension, increased arterial stiffness, disturbed wave reflexion and prognosis depending on ankle-brachial pressure index. This review summarises the physiology of pulse wave propagation and reflection and its changes due to aging and atherosclerosis. We discuss different non-invasive assessment techniques and highlight the importance of the understanding of arterial pulse wave analysis for each vascular specialist and primary care physician alike in the context of PAD.

Background: We compared medical secondary prevention in patients with peripheral arterial disease stage II (Fontaine) located in the femoro-popliteal artery managed by vascular surgeons and medical doctors / angiologists in our multidisciplinary vascular center. Patients and methods: We retrospectively analyzed demission protocols of in-hospital treatments between 01.01.2007 and 20.06.2008. Results: We surveyed 264 patients (54.2 % women; mean age 67.52 ± 8.98 yrs), 179 (67.8 %) primarily treated by medical doctors / angiologists and 85 (32.2 %) primarily managed by vascular surgeons. Medical doctors / angiologists treated more women (n = 109) than men (n = 34), (p = 0.002) and documented smoking and diabetes mellitus more often (p < 0.001) than vascular surgeons. Besides, patients had similar cardiovascular risk profiles and concomitant diseases, vascular surgeons prescribed 5.47 ± 2.26 drugs, medical doctors / angiologists 6.37 ± 2.67 (p = 0.005). Overall, 239 (90.5 %) patients were on aspirin, 180 (68.2 %) on clopidogrel, and 18 (6.9 %) on oral anticoagulants. Significantly more patients treated by medical doctors / angiologists received clopidogrel (169 versus 11; p < 0.001), significantly more surgical patients received oral anticoagulants (11 versus 7; p = 0.016). The number of patients without prescriptions for any antithrombotic therapy was 6 (6.9 %) in patients treated by vascular surgeons and 0 (0 %) in patients managed by medical doctors / angiologists (p = 0.001). Prescription-rates of β-blockers, ACE-inhibitors, Angiotensin II-antangonists, calcium channel blockers, and diuretics were statistically not different between the two disciplines, but statins were prescribed significantly more often by medical doctors / angiologists (139 versus 49; p < 0001). With the exceptions of Clopidogrel (women > men) and diuretics (men > women) we observed no gender-specific prescriptions. Conclusions: We observed high prescriptions rates of secondary medical prevention in patients primarily treated by medical doctors / angiologists and vascular surgeons. We believe that this result is highly influenced by our multidisciplinary approach. Nevertheless, efforts have to be made to raise vascular surgeon’s awareness of statin use and complete prescription of antithrombotic and antiplatelet drugs.
