Patients and Methods
From May 1997 to December 2005, the hospital records and clinic charts of all patients who were diagnosed with symptomatic DVT and who underwent interventional therapy were analyzed. Patients who underwent PMT therapy using the AngioJet system during this time period were identified. For the purpose of comparison, these patients who received PMT therapy were compared to a cohort group who underwent CDT therapy. Data obtained included patient demographics, DVT risk factors, periprocedural data,
Results
During this study period, a total of 93 patients who underwent 98 catheter-directed interventions for DVT were included in the study. Among them, CDT or PMT was performed in 46 (47%) and 52 (53%) procedures, respectively (Table 1). Specifically, patients’ symptoms that led to the catheter-based intervention included lower extremity swelling (n = 34 in the PMT group, n = 29 in the CDT group), incapacitating pain (n = 14 in the PMT group, n = 12 in the CDT group), or phlegmasia dolen (n = 4 in
Comments
While many studies have reported the technical feasibility and satisfactory early outcomes of a variety of interventional treatment modalities of symptomatic DVT [9], [15], [16], [17], [18], the ideal treatment strategy for this condition remains a subject of debate. Our study is notable because it represents the first clinical study comparing the treatment outcomes of 2 well-described interventional strategies for severe deep venous thrombosis. In addition, our study demonstrated the
