However, chronic kidney disease (CKD) is: (1) highly frequent in VTE patients; (2) strongly linked to VTE; and (3) a risk factor for cardiovascular morbidity/mortality and fatal pulmonary embolism. Therefore, an increasing number of patients are presented with CKD and VTE and more and more physicians must face the questions of the management of these patients and that of the handling of anticoagulant agents in CKD patients because of the pharmacokinetic modifications of these drugs in this population. These modifications may lead to overdosage and dose-related side effects, such as bleeding. It is therefore necessary to screen VTE patients for CKD and to modify the doses of anticoagulants, if necessary.

The aim of our study was to assess the prevalence of peripheral arterial disease by measuring the ankle-brachial pressure index in patients at high cardiovascular risk and to study the risk factors associated with this disease. METHODOLOGY: This was a descriptive and analytic cross-sectional study which focused on 370 patients seen at the medical consultation for atherosclerosis prevention. The ankle-brachial index was measured with a portable Doppler (BIDOP 3) using 4 and 8Hz dual frequency probes. The standards were: normal ankle-brachial index 0.9 to 1.3; peripheral artery obstructive disease ankle-brachial index less than 0.9; poorly compressible artery (medial arterial calcification) ankle-brachial index greater than 1.3. Cardiovascular risk factors were also studied. RESULTS: Three hundred and seventy subjects (mean age 65.5±8.7years) were screened Cardiovascular risk factors were: sedentary lifestyle (91.5 %), hypertension (68.1 %), elevated LDL-cholesterolemia (36.3 %), diabetes (48.3 %) and tobacco smoking (33.8 %). The prevalence of peripheral artery disease was 32.4 % of which 77.5 % were asymptomatic. We found a significant correlation with smoking, diabetes, dyslipidemia and the presence of coronary artery disease or vascular cerebral disease. Screening for peripheral arterial disease (PAD) with the ankle-brachial index has increased the percentage of polyvascular patients from 6.2 to 29 %. Factors independently associated with PAD were advanced age, presence of cardiovascular disease, smoking and glycated hemoglobin. CONCLUSION: PAD is a common condition in people at high cardiovascular risk, the frequency of asymptomatic forms justifies the screening with pocket Doppler which is a simple, inexpensive and effective test to assess the overall cardiovascular risk.

The diagnosis may be challenging. CASE REPORT: A 23-year-old female right-handed French teacher and amateur violin player presented with edema of the root of the right arm associated with erythrocyanosis of the extremity and collateral circulation of the shoulder. History taking revealed oral contraception and recent change in violin playing habits. D-dimers were negative. A second duplex-Doppler was required before visualization of a DVT in the right subclavian vein. The patient was given low-molecular-weight heparin alone, followed by rivaroxaban. The outcome was very favorable at 48h. The patient was seen at 4 months and had not had a recurrent episode. DISCUSSION: The diagnosis of DVT of the upper limb is basically clinical. There is a clinical probability score for the introduction of anticoagulation even if the duplex-Doppler fails to visualize DVT, a situation that can occur due to the clavicular superposition in this region. Exercise-induced DVT should be suspected in patients with minimally intense but repeated exercise (hyper-abduction), e.g. as here playing the violin. Anticoagulation is the treatment of choice. The role for surgery and pharmacomechanical strategies remains to be defined. CONCLUSION: Exercise-induced thrombosis (Paget-Schroetter syndrome) should be suspected in young patients free of any comorbidity who develop a thrombosis of the upper limb. Studies comparing different therapeutic options would be useful to achieve more homogeneous management practices despite the heterogeneous clinical presentations.

METHOD: An analysis of the 2013 data from a random sample of ≈600,000 patients registered in the French National Health Insurances reimbursement database was conducted to identify platelet counts performed during injectable anticoagulants exposure period and treatment interruptions due to heparin-induced thrombocytopenia or transfusion. Events were then valued to establish associated costs. RESULTS: Overall 15,985 adult patients representing a cumulated injectable anticoagulants exposure time of 12,264 months were selected. Treatment sequences involved unfractionated heparin (2.8%), low molecular weight heparin (86.9%), and fondaparinux (13.1%). Patients treated with unfractionated heparin were older (77 vs. 57 and 59 years) with longer treatment duration (32.6 vs. 25.1 and 21 days). After statistical adjustment, the average monthly number of platelet counts was 1.36-fold lower in patients treated with fondaparinux compared to low molecular weight heparin (P<0.0001). No difference was found between low molecular weight heparin and fondaparinux regarding the incidence of bleeding with transfusion (P=0.76) or hospitalized thrombocytopenia (P=0.82). Extrapolated for the whole country, the estimated costs for biological monitoring were € 21.6 million for low molecular weight heparin and € 0.9 million for fondaparinux. CONCLUSION: Significantly fewer platelet counts were performed among patients treated with fondaparinux than among patients receiving low molecular weight heparin without additional bleeding risk. This finding should be taken into account when assessing the costs of such treatments.

The companies are trying to replace VKA by DOACs, totally or at least greatly VKA should VKA disappear in favor of DOACs? There are still many questions about DOACs. The purpose of this article is to make a well-considered decision in this area. The aim is not to denigrate one or the other but to share things between these two families of anticoagulants. Physicians using these drugs must have a full knowledge about compared efficacy and safety. We feel necessary to increase distance between effective results of the clinical trials and industrial communication around DOACs.

Immediate adverse effects are mainly represented by visual disturbances. We are reporting the case of an immediate transient faintness following two sessions of foam sclerotherapy. OBSERVATION: An 80-year-old active female with superficial chronic venous disorder and no significant medical or surgical backgrounds experienced two similar immediate general adverse events following two sessions of sclerotherapy from a total of five. Adverse reactions included faintness, associated with headache but without visual disturbance, lasting ten minutes with full short and long-term recoveries. The common factor between those two sessions was the injection of a higher volume of sclerosing agent compared to the other sessions, 5mL of which was foam. CONCLUSION: Age is not a contraindication of foam sclerotherapy. Nevertheless, we must proceed with caution even when moderate quantities of foam are required.

However, paraneoplastic SSc is not well known. The aim of this article is to describe cases of paraneoplastic systemic sclerosis and to compare them to other cases of the literature, to find characteristics that can make suspect a paraneoplastic mechanism when SSc is diagnosed. METHODS: We retrospectively analyzed patients, in our department who, over the last 15 years, presented with Raynaud's phenomenon with a diagnosis of SSc (including cancer during the period of SSc). Treatment of cancer had to be concomitted with an improvement of sclerosis and/or negativation of antinuclear antibodies. Review analysis of other cases was made with Pubmed. RESULTS: Three patients responded to the criteria. Two of them had an ovarian cancer with peritoneal carcinomatosis and a concomitted SSc. One had a colon cancer with an ovarian metastasis diagnosed 1 year before SSc. None of them had anti-ENA antibody. One had a normal capillaroscopy. After treatment of cancer, all of them had an improvement of sclerosis and a negativation of antinuclear antibodies. CONCLUSION: We believe that physicians should be aware of paraneoplastic SSc when presentation of SSc is atypical: no anti-ENA (anti-SCl70 or anti-centromere) or normal capillaroscopy, in particular gynecologic cancer in women.

Vascular damage due to these injuries may threaten limb loss. In some cases, the signs of ischemia may not be evident just after the injury and may only appear later on. Therefore, a high index of suspicion is essential. It is important to bear this association in mind, so as to make an early diagnosis and avoid serious complications. We are describing the case of a young patient involved in a motor vehicle crash with an axillary artery trauma due to the surgical neck of humerus fracture. The patient underwent a basilic vein grafting, the postoperative course was good.

MATERIALS AND METHODS: National multicenter prospective observational study related to COPART II centers. From 2010 through 2014, 64 subjects hospitalized for critical limb ischemia and already treated by aspirin before the VerifyNow test were included. A VerifyNow test>550 ARU was defined as aspirin resistance. Critical limb ischemia was defined according to the TASC I criteria. The primary outcome was a composite including death, acute coronary syndrome, stroke and major amputation during the one-year follow-up period. RESULTS: In all, 9/64 patients were aspirin resistant, the status was confirmed in one case. The prevalence of aspirin resistance was 14.06%. There was no significant difference between aspirin resistant and aspirin non-resistant groups in terms of cardiovascular history and glycemia status. Neither was there significant difference between the two groups in terms of survival. CONCLUSION: Aspirin resistance was not predictive of poorer survival in critical limb ischemia patients. However, our population was limited. Considering that a clear definition of aspirin resistance and standardized diagnostic tests are lacking, complementary studies might be useful.

We are reporting on a 36-year-old female patient presenting with co-existing cerebral venous thrombosis and subdural hemorrhage. The coagulation screening showed a prolonged prothrombin time (PT), activated partial thromboplastin time (aPTT), and a normal fibrinogen level and platelet count. Evaluation of the clotting factors revealed decreased levels of factors II (37%). Factors V, VIII, IX and XI were normal. Lupus anticoagulant (LA) was demonstrated by the Dilute Russell's Viper Venom Test (DRVVT). Immunological work-up was positive for IgG type anticardiolipines antibodies (aCL). Successful management consisted first of oral prednisone (60mg/d). Thus, anticoagulation was introduced once factor II had stabilized.

Healing can be long for venous ulcers and the risk of complications is significant. Infection is the most severe complication and can occur in the form of easily diagnosed acute bacterial dermohypodermitis that generally responds well to antibiotic treatment if given at an appropriate dose or in the form of localized infection that is more difficult to diagnosis. Indeed, no consensus has been reached in the literature on the clinical criteria to retain for the diagnosis of localized infection. Similarly, the most appropriate treatment remains to be established. Local care would be a logical starting point, followed by systemic antibiotics if this approach is unsuccessful. Individual conditions also should be taken into consideration (immunodepression, severe arteriopathy warranting more rapid use of systemic antibiotics). The second most frequent complication is an allergic reaction to a topical agent used for wound care. The rate of sensitivization in patients with leg ulcers is high (60 %), although the rate is declining with modern dressings. No product can be considered perfectly safe for these polysensitized patients. Dermocorticoid therapy can be very effective. Allergology tests are needed. Certain leg ulcers require special care from diagnosis. An arterial origin must be suspected for deep, or necrotic ulcers. Arterial supply must be explored rapidly, followed by a revascularization procedure when necessary. Highly painful superficial extensive necrotic ulcers due to necrotic angiodermitis require hospital care for skin grafts that will control the antiodermitis and provide pain. Carcinoma should be suspected in cases of leg ulcers with an atypical localization exhibiting excessive budding. A biopsy is mandatory for leg ulcers with an unusual course (absence of healing despite well-conducted care).
Compression therapy is a mandatory treatment of leg ulcers whether the goal is cure (stage C6 in the international classification for chronic venous disease) or prevention of recurrence (stage C5). Different indications...Compression therapy is a mandatory treatment of leg ulcers whether the goal is cure (stage C6 in the international classification for chronic venous disease) or prevention of recurrence (stage C5). Different indications for compression therapy were proposed by the French Superior Health Authority (HAS) in 2010, but new studies have modified attitudes since that time. Considering the very large number of options available, the many co-morbid conditions observed in these patients, as well as patient age and available assistance, it is important to adapt to the variable clinical and social situations encountered. One must keep in mind that a well-controlled treatment should improve trophic disorders and patient comfort. A poorly-adapted treatment with little or even deleterious effect will be abandoned by the patient.

The treatment of these ulcers is crucial for patients because pain has a significant impact on their daily lives. The analgesic effect of punch skin grafting (PSG) for the treatment of painful ulcers is not well described. The objective of the study is to assess the level of pain in patients with an ulcerated wound and to see if there is an analgesic effect of PSG. PATIENT AND METHODS: It was a single-center, non-interventional study conducted in hospitalized patients with one or several ulcer(s) of any type and which has been painful for more than six weeks. Pain was assessed before, the day after a PSG and then on the way out of hospital by a questionnaire and a numeric pain rating scale. Permanent pain and pain peaks were identified. RESULTS: Forty one patients were included (23 men and 18 women) with mean age of 73±21 years, 36% (n=15) with arterial ulcers, 36% (n=15) with venous ulcers, 12% (n=5) with necrotic angiodermatitis, 12% (n=5) with mixed ulcers and 4% (n=2) with "other ulcers" (due to infection and use of Hydroxycarbamide). On day 1 of PSG, patients showed an improvement in terms of permanent pain (77%, n=24/31) and pain peaks (90%, n=37/41) respectively and 90% (n=28/31) and 95% (n=39/41) on the last day at hospital. Reduction in the use of strong opioids was found in 13 patients (81%). CONCLUSION: Punch skin grafting is a simple and validated treatment, which can reduce or eliminate pain related to ulcers. It has an effect on permanent pain and pain peaks. Its efficacy is particularly demonstrated on venous ulcers and mixed ulcers but also initially painful ulcers such as necrotic angiodermatitis or arterial ulcers.

The prima...One third of patients with critical limb ischemia (CLI) has below the knee lesions and requires a restoration of direct blood flow into the foot. However, many of these patients are ineligible for open surgery. The primary goals thus become pain relief and limb salvage over patency. The angiosome concept helps determine the target artery to treat in priority. The endovascular approach has decreased morbidity and mortality rates compared to distal bypass surgery; while subintimal retrograde, trans-collateral and loop techniques push the limits of open surgery by reopening the plantar arch, thereby improving run-off. Early restenosis phenomena after angioplasty have been improved by the use of - limus drug eluting balloons and balloon expandable stents in case of flow limiting dissection or recoil with increased limb salvage rates. Moreover, drug-eluting stents have been proposed, and allow a reduction in reintervention and in-stent restenosis rates in short lesions; however, results on amputation rates or survival are limited. Vessel preparation is a key to overcoming some current limitations, including atherectomy, which increases technical success rates and reduces restenosis rates, especially in calcified lesions, chronic total occlusions and restenosis. These advanced techniques in distal endovascular revascularization have revolutionized limb salvage and support the interest of an endovascular first approach in CLI treatment.

Care must be perfectly adapted to each individual patient, the specificities of each particular wound, and the underlying vascular disease. The goal is to achieve wound healing. Inappropriate care can retard healing or even aggravate the wound. The skin should be cleaned with water a non-allergic detergent and should concern the entire limb in addition to the wound itself. Fibrin or necrosis detersion is an important step that can be painful. Different tools are available. The skin around the wound should be hydrated and protected, focusing on fragile areas, such as the tibial crest and heals, in order to prevent the development of new wounds. Other more complex interventions include tenosynovectomy, bone gouging and reduction of the necrotic toe that when properly performed can prevent a new passage in the operating room. If the ischemia becomes critical, the foot should be held warm with a carded cotton, taking care to separate the toes with dry dressings in order to preserve the healthy tissue and avoid induced wounds. Finally, compression bands are indispensable in cases with edema or venous hyperpressure. A skillful banding technique is essential, especially for legs with complex morphology.

It is well known during wound care but can occur at any time. The pain is often a complex phenomenon involving nociceptive pain, neuropathic pain, anxiety and emotional suffering, all directly related to the chronic disease. Care for the patient suffering from pain must take into consideration all of these aspects of the disease. The therapeutic strategy should rely on the use of different pharmacological agents, well-adapted local care using the different available analgesic tools and include psycho-affective care.
