To determine the chronological changes of venous physiology following major thromboses, 20 patients were repeatedly examined for over 5 years after an acute ilio-femoral thrombosis which was treated with conventional anticoagulation. Radionuclide angiography showed that 70% of the patients had obstructive lesions of the iliac vein with only minor changes(More)

The paper presents and evaluates a hybrid implementation of a low complexity algorithm for speech enhancement, the adaptive gain equalizer (AGE). The AGE is a subband based time domain method for instantaneous boosting of speech. By a combination of digital analysis and analog synthesis, the main advantages of the digital and analog domains are utilized.(More)
In a 7-center Scandinavian double-blind placebo-controlled study of 179 patients with intermittent claudication, the effect of the serotonin antagonist ketanserin was evaluated on walking distance, brachial and ankle blood pressure, and symptoms. For all centers together, pain-free walking distance was significantly increased after 6 months with both(More)
OBJECTIVE To establish sex and age related reference values for venous strain-gauge plethysmography. DESIGN Strain-gauge plethysmography measurements in healthy volunteers. SETTING Examinations performed in a University Hospital (Malmö) and a County Hospital (Kalmar). PARTICIPANTS Healthy volunteers, without history or signs of venous insufficiency.(More)
Forty-one patients with acute iliofemoral venous thrombosis were randomised to conventional anticoagulation or acute thrombectomy combined with a temporary arterio-venous fistula (AVF) and anti-coagulation. Follow-up after 5 years in 22 medical and 19 surgical patients revealed slightly more asymptomatic patients (37 vs. 18%) and less frequent severe(More)
In a Swedish survey, leg ulcer disease has been found to have a prevalence of around 1%. The multifactorial etiology requires a multidisciplinary approach. Forty-three patients with leg ulcers have been examined clinically and by pathophysiological and roentgenological investigations. Proper conservative treatment was instituted in 25 of the patients, and(More)
