A large multicenter study has recently questioned the overall clinical efficacy of vena caval filters, especially when inserted prophylactically, because of the subsequent development of deep venous thrombosis (DVT) at the insertion site. We examined the incidence of this complication with newer, smaller diameter percutaneous devices. ⋯ There is a continuing and significant incidence of new DVT development ipsilateral to the percutaneous femoral insertion site of vena caval filters. The smaller diameter filters are not associated with a lower incidence of femoral thrombosis.

The clinical diagnosis of deep vein thrombosis (DVT) is unreliable in more than 50% of cases, and, in recent years, plasma D-dimer assays have been used to predict the presence of DVT with high sensitivity and negative predictive values. This study investigated the use of a rapid whole blood test that could be performed and interpreted by the bedside in addition to a clinically derived risk assessment score (RAS) to determine whether a practical and cost-effective clinical model could be developed for the diagnosis and exclusion of DVT in symptomatic patients. ⋯ A combination of clinical assessment and rapid D-dimer testing provides an effective means of excluding proximal DVT in symptomatic patients. The application of a clinical diagnostic model on the basis of these parameters has the potential for saving a large proportion of unnecessary duplex scans with the associated time and costs.

We set out to assess the new Aberdeen Varicose Veins Questionnaire (Aberdeen Questionnaire) for the properties necessary for a valid measure of health outcome, to determine quality of life of patients with varicose veins, and to determine the effect of surgery on quality of life. ⋯ The Aberdeen Questionnaire is a valid measure of quality of life for patients with varicose veins. Persons with varicose veins have a reduced quality of life compared with the general population, and this discrepancy is significantly improved at 6 weeks by operating on them.

We sought to determine the efficacy of antiplatelet therapy and oral anticoagulants in maintaining graft patency and preventing ischemic complications in patients after infrainguinal bypass surgery. ⋯ Antiplatelet therapy and oral anticoagulants reduce the risk of graft occlusion. Oral anticoagulant therapy appears to be the more effective treatment in high-risk patients. Data on the reduction of the risk of stroke, myocardial infarction, and death are inconclusive. Evidence for the beneficial effects of antiplatelet and oral anticoagulant therapy after infrainguinal bypass surgery is based on a small number of trials only. There is no proof as to which modality is the most effective in the prevention of graft occlusion and ischemic events in patients after infrainguinal bypass surgery, which is reason for a randomized comparison of aspirin with oral anticoagulants.

The low invasiveness of endoluminal abdominal aneurysm repair (EAAR) appears optimal for the use of epidural anesthesia (EA). However, reported series on EAAR show that general anesthesia (GA) is generally preferred. To evaluate the feasibility and problems encountered with EA for EAAR, patients undergoing EAAR with EA and patients undergoing EAAR with GA were examined. ⋯ EA for EAAR is feasible in a high percentage of patients in whom it is attempted, and it ensures a technical outcome comparable with that of patients undergoing EAAR with GA. Successful completion of EAAR with EA is associated with a short period of hospitalization.
