Abstract
BACKGROUND: This study aims to evaluate the clinical and ultrasonographic long-term results of additional thrombolytic therapy to pharmacomechanical thromboaspiration in patients with acute and subacute lower extremity deep vein thrombosis. METHODS: Medical data of a total of 68 patients ( 41 males, 27 females; mean age 38 years; range, 25 to 56 years) who were admitted to our department with the diagnosis of hyperacute or acute deep vein thrombosis between January 2013 and January 2015 were retrospectively analyzed. The patients were divided into two groups: thrombectomy without thrombolytic therapy (Group 1, n=33) and thrombectomy with thrombolytic therapy (Group 2, n=35). All patients were administered Clinical Symptom Scoring and Doppler ultrasonography at one, six, and 12 months. RESULTS: Clinical symptom scores were higher in Group 1 at one month (p<0.001), while there was no significant difference between the groups at six months (p=0.102). Group 1 had higher scores at 12 months (p=0.043). The complete patency rates for both groups were similar at one month (p=0.181); however, the rates were higher in Group 2 at six and 12 months (p=0.019 and p=0.002, respectively). There was no significant difference in the complete patency rates between the groups at one and six months (p=0.563 and p=0.064, respectively), while these rates were higher in Group 2 at 12 months (p=0.013). In patients with acute deep vein thrombosis, the complete patency rates were found to be higher in all control Doppler ultrasonography examinations. CONCLUSION: In the treatment of both hyperacute and acute deep vein thrombosis, the addition of thrombolytic therapy to pharmacomechanical thromboaspiration improves the clinical symptoms and venous patency rates.
