Assessing the risk of recurrent venous thromboembolism – a practical approach
Jennifer Fahrni,1 Marc Husmann,2 Silvia B Gretener,3 Hong H Keo1 1Division of Angiology, Medical University Clinic, Kantonsspital Aarau AG, Aarau, Switzerland; 2Clinic for Angiology, University Hospital, University of Zurich, Zürich, Switzerland; 3Clinic for Angiology Oberaargau, Langenthal, Switzerland Abstract: Recurrent venous thromboembolism (VTE) is associated with increased morbidity and mortality. This risk is lowered by anticoagulation, with a large effect in the initial phase following the venous thromboembolic event, and with a smaller effect in terms of secondary prevention of recurrence when extended anticoagulation is performed. On the other hand, extended anticoagulation is associated with an increased risk of major bleeding and thus leads to morbidity and mortality. Therefore, it is necessary to assess the risk of recurrence for VTE on an individual basis, and a recommendation for secondary prophylaxis should be specifically based on risk calculation of recurrence of VTE and bleeding. In this review, we provide a comprehensive summary of relevant risk factors for recurrent VTE and a practical approach for assessing the risk of recurrence in daily practice.

Disseminated intravascular coagulopathy caused by endoleak type I: successful treatment by endovascular stent-graft extension
IntroductionWe present a case with acute DIC probably caused by a type I endoleak after endovascular aneurysm repair (EVAR).Case reportAn 84-year-old male underwent elective EVAR of a 7cm sized infrarenal aortic aneurysm and developed five months later an acute DIC associated with an endoleak type I. After successful endovascular stent-graft extension the DIC resolved.DiscussionEndoleak type I is not described to be related to DIC, however as the endovascular stent-graft extension did abolish both, endoleak and the DIC in our case. We therefore suggest that a type I endoleak can cause acute DIC
Influence of pulmonary status and diabetes mellitus on aortic neck dilatation following endovascular repair of abdominal aortic aneurysms: a EUROSTAR report
PURPOSE: To elucidate the association of impaired pulmonary status (IPS) and diabetes mellitus (DM) with clinical outcome and the incidences of aortic neck dilatation and type I endoleak after elective endovascular infrarenal aortic aneurysm repair (EVAR). METHODS: In 164 European institutions participating in the EUROSTAR registry, 6383 patients (5985 men; mean age 72.4+/-7.6 years) underwent EVAR. Patients were divided into patients without versus with IPS or with/without DM. Clinical assessment and contrast-enhanced computed tomography (CT) were performed at 1, 3, 6, 12, 18, and 24 months and annually thereafter. Cumulative endpoint analysis comprised death, aortic rupture, type I endoleak, endovascular reintervention, and surgical conversion. RESULTS: Prevalence of IPS was 2733/6383 (43%) and prevalence of DM was 810/6383 (13%). Mean follow-up was 21.1+/-18.4 months. Thirty-day mortality, AAA rupture, and conversion rates did not differ between patients with versus without IPS and between patients with versus without DM. All-cause and AAA-related mortality, respectively, were significantly higher in patients with IPS compared to patients with normal pulmonary status (31.0% versus 19.0%, por=15%, and type of stent-graft, the presence of IPS was not associated with significantly higher rates of aortic neck dilatation (30.6% versus 38.0%, p>0.05) and did not influence cumulative rates of type I endoleak, endovascular reintervention, or conversion to open surgery (p>0.05). Similarly, the presence of DM did not influence the above-mentioned study endpoints. CONCLUSION: In contrast to observations regarding the natural course of AAAs, impaired pulmonary status does not negatively influence aortic neck dilatation, while the presence of diabetes does not protect from these dismal events after EVAR

Doença cĂstica adventicial da artĂ©ria poplĂtea: causa infrequente de claudicação intermitente
Critical ischemia of the fingers in an auto mechanic as a result of occupational exposure
Hypothenar hammer syndrome is a rare cause of ischemic fingers observed mainly in young men smoking cigarettes and it is associated with repeated trauma of the ulnar artery in the area of the hypothenar eminence of the dominant-hand arm, resulting in a deficit of blood supply with the occurrence of hand symptoms typical for chronic and sometimes critical ischemia. Artery injury in this location is most often the result of multiple repetitions of the same activity being mostly the result of occupational exposure. We present a case of a 27-year-old car mechanic admitted to the hospital with symptoms of critical ischemia of the fingers III, IV, and V of the right hand, which resolved after conservative treatment
