Extremity Deep Venous Thrombosis (extremity + deep_venous_thrombosis)
Selected AbstractsIliac vein compression syndrome: An underdiagnosed cause of lower extremity deep venous thrombosis,JOURNAL OF HOSPITAL MEDICINE, Issue 7 2010Ami Naik BS Abstract Iliac vein compression syndrome (CS) is a rare cause of deep venous thrombosis. It is caused by an anatomic anomaly in which the right common iliac artery overlies the left common iliac vein causing mechanical compression. Subsequent endothelial changes within the vessels have the potential to spur thrombus formation. Aggressive diagnostic and therapeutic interventions must be implemented upon suspicion to avoid long-term complications. We report on a 19 year old male who presented with ICS. We discuss the clinical presentation, diagnosis, and current treatment options. Journal of Hospital Medicine 2010. © 2010 Society of Hospital Medicine. [source] Old and new risk factors for upper extremity deep venous thrombosisJOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 11 2005J. W. BLOM Summary.,Background: Well known risk factors for upper extremity deep venous thrombosis are the presence of a central venous catheter (CVC) and malignancy, but other potential risk factors, such as surgery, injury and hormone replacement therapy (HRT), have not yet been explored. Methods: We performed a population-based case-control study including 179 consecutive patients, aged 18,70 years with upper extremity deep venous thrombosis and 2399 control subjects. Participants reported on acquired risk factors in a questionnaire and factor V Leiden and prothrombin 20210A mutation were ascertained. Information on CVC was obtained from discharge letters. Results: Forty-two patients (23%) and one control subject (0.04%) had a CVC (ORadj: 1136, 95% CI: 153,8448, adjusted for age and sex). Cancer patients without a CVC had an eightfold increased risk of venous thrombosis of the arm (ORcrude: 7.7, 95% CI: 4.6,13.0). Other evident risk factors were prothrombotic mutations, surgery, immobilization of the arm (plaster cast), oral contraceptive use and family history, with odds ratios varying from 2.0 up to 13.1. The risk in the presence of injury and during puerperium was twofold or more increased, although not significantly. In contrast HRT, unusual exercise, travel and obesity did not increase the risk. Hormone users had an increased risk in the presence of prothrombotic mutations or surgery. Obese persons (BMI > 30 kg m,2) undergoing surgery had a 23-fold increased risk of arm thrombosis compared with non-obese persons not undergoing surgery. Conclusion: A CVC is a very strong risk factor for arm thrombosis. Most risk factors for thrombosis in the leg are also risk factors for arm thrombosis. [source] Asymptomatic lower extremity deep venous thrombosis resulting in fibula free flap failure,THE LARYNGOSCOPE, Issue 6 2009Adam S. Jacobson MD Abstract Objectives/Hypothesis: The successful harvest and transplant of a fibular flap depends on many factors, including healthy inflow and outflow systems. A contraindication to harvesting a fibular flap is disease of the lower extremity arterial system; therefore, preoperative evaluation of the arterial system is routine. Preoperative evaluation of the venous system is not routine, unless there is clinical suspicion of venous disease. Methods: Retrospective chart review. Results: Two cases of occult deep venous thrombosis (DVT) were encountered intraoperatively resulting in nontransplantable flaps. Conclusions: This finding represents a serious concern, and we believe that venous imaging should be considered in patients with significant risk factors for harboring an occult DVT.
