[Clinically silent pulmonary embolism in patients with proximal deep venous thrombosis].
In 18 patients with proximal deep venous thrombosis (PDVT) confirmed by phlebography, no symptoms and signs of pulmonary embolism (PE) were observed. All patients were treated with nadroparin. During first 6 days of treatment in all patients perfusion lung scans were performed. 8 patients (44.4%) of all group developed lung scans positive for PE (silent PE). Period of successful treatment of PDVT was 10 days. No evidence of recurrent PE were observed during the period of treatment. We conclude that: 1. Frequency of silent PE in patients with PDVT is very high-lack of symptoms and signs of PE does not exclude the presence of PE in this group of patients. 2. In all patients with PDVT perfusion lung scan should be performed even in cases with no symptoms and signs of PE. 3. Low molecular weight heparins administered subcutaneously are effective in treatment either silent PE or PDVT.
