backgrounds: there are controversies among surgeons about prophylaxis of deep vein thrombosis (dvt) in laparoscopic cholecystectomy. the aim of this study was the assessment of patients’ condition after laparoscopic cholecystectomy without any prophylactic measure. methods: 100 cases of laparoscopic cholecystectomy without dvt prophylaxis were followed by duplex scanning in the first postoperat...

The duplex scan is the main tool used to diagnose carotid artery stenosis, and there is agreement that it might be the single preoperative diagnostic test. All limitations of carotid duplex scanning should be taken into consideration during qualification to surgical or endovascular treatment. Awareness of these limitations is especially important when neurological symptoms are typical and duple...

BACKGROUND Guidelines advocate that a negative ultrasonographic scan needs to be followed by venography, or a repeat scan after 1 week, to detect potentially missed calf vein thrombosis. This study aimed to evaluate whether anticoagulation can safely be withheld on the basis of a single negative duplex scan in patients presenting with suspected deep venous thrombosis (DVT). METHODS Duplex sca...

BACKGROUND The incidence of deep venous thrombosis is 0.6/1000 habitants and when symptomatic its diagnosis by duplex scan has 100% sensitivity and 98% specificity. OBJECTIVES The aim of this study was to evaluate the findings of the duplex scan in patients with clinical suspicion of deep venous thrombosis. METHODS 239 consecutive outpatients (59.2 +/- 18.6 years, 164 female) were evaluated...

AIM The contribution of lower extremity venous duplex scan to the diagnostic strategy for pulmonary embolism has been demonstrated by many authors. However, the positive diagnostic value of this noninvasive test in clinically suspected pulmonary embolism is not very high (10% - 18%). Since thromboembolic risks increase considerably in hospitalized patients with advanced age, this study aims to ...

The incidence of bilateral deep venous thrombosis in patients with single limb or bilateral symptoms was determined using duplex scan examination. In a prospective study, 157 inpatients with clinical suspicion of deep venous thrombosis underwent duplex scan evaluation of the lower extremities. Demographic characteristics, physical examination data, and risk factor information were collected. In...
