[Strain gauge plethysmography of venous circulation in aged patients with deep vein thrombosis and post-phlebitis syndrome].
Deep-seated venous thrombosis (DVT) is more common in subjects over 40 and is most frequently found in subjects between 60 and 70 years of age. It is thought that the complaint is brought about by paraphysiological factors connected with aging or conditions frequently encountered in the elderly which are interconnected to varying extents. The flow parameters of 30 female subjects with diagnosed DVT, of which 18 were over 60, and 24 female subjects with a phlebographic diagnosis of Post-phlebocytic syndrome (PPS), of which 14 were over 60, were evaluated using the plethysmographic strain gauge technique. Women over 60 with DVT have longer maximum emptying times and higher venous pressures. For this group, maximum emptying time is slightly lower (although not by a statistically significant amount) than for the younger group. Subjects of advanced age with DVT display significantly higher levels of venous obstruction and patients with PPS display higher levels of venous ectasia. These effects are probably caused by venous circulation miopragia due to aging.
