title: One-year sequential follow-up of venous emptying rate and leg temperature profiles after acute deep vein thrombosis.
abstract: In order to study the natural course of venous flow and temperature reaction in the legs after symptomatic first episode of deep vein thrombosis (DVT), 65 patients (57 with proximal DVT) without further thromboembolic complications during the observation period were followed for 1 year by repeated plethysmography (PG) and thermography (TG). Regarding the non-invasive parameters substantial individual variations was observed during the observation period. After 1 year pathologic PG and TG were still demonstrated in 39% (I mu (95%) = /0.43 +/- 0.05/) and 65% (I mu (95%) = /1.18 +/- 0.11/), respectively, of the patients after proximal DVT. Only a minority of the patients were normalized permanently in both PG and TG during the first year. The high frequency of remaining venous obstruction and especially, persistent thermoactivity is notable and may be of clinical importance.
