Pulmonary embolism in acute iliofemoral venous thrombosis

摘要: Serial perfusion lung scanning and chest radiography were used to study the incidence of pulmonary embolism in patients with acute iliofemoral venous thrombosis. The efficacy conventional anticoagulation surgical thrombectomy controlling risk creating emboli during also evaluated. Lung scans obtained on admission 49 normal 37 per cent, inconclusive 18 cent positive for 45 patients. Symptoms suggestive present only 24 correlated poorly scans. Massive was two Additional, usually asymptomatic, developed within one month 21 29 treated conservatively alone 20 having combined a temporary arteriovenous fistula systemic anticoagulation. Only patient required caval interruption. Pulmonary embolism, minor degree, is thus nearly every other Anticoagulation or conjunction most cases effectively prevents further embolization additional by procedure insignificant.
