The clinical usefulness of catheter fragmentation and aspiration therapy was studied in 8 patients with acute pulmonary embolism who received thrombolytic therapy using urokinase or tissue-type plasminogen activator (t-PA) (thrombolysis group) and 8 patients who underwent catheter fragmentation and aspiration therapy using a percutaneous transluminal coronary angioplasty (PTCA) guide catheter (catheter group). The patients were selected from 20 patients with a definite diagnosis of acute pulmonary embolism based on pulmonary arteriography and nuclear imaging. Urokinase (48 x 10(4) to 96 x 10(4) unit/day) or t-PA (12 x 10(6) unit/day) was administered intravenously for mean 4 days in the thrombolysis group. Pulmonary artery pressure was first measured using a Swan-Ganz catheter via the jugular vein or the femoral vein in the catheter group. Then, a PTCA guide catheter was advanced into the pulmonary artery, and the thrombus was disrupted repeatedly using a Radifocus wire, followed by manual aspiration. Subsequent treatment consisted of intravenous infusion of heparin (10,000 to 15,000 unit/day) and urokinase (24 x 10(4) to 48 x 10(4) unit/day) for mean 6 days. Partial revascularization was achieved in all patients in both groups. Five patients in the thrombolysis group died within 1 month due to respiratory failure, re-embolization, and/or hemorrhagic complications. One patient in the catheter group died of hemorrhagic shock. Pulmonary artery systolic pressure in the catheter group was significantly reduced from 47.4 to 26.5 mmHg (p < 0.01). Catheter treatment of acute pulmonary embolism associated with acute circulatory failure such as shock can lead to rapid hemodynamic improvement. In contrast, thrombolysis is an effective treatment, but bleeding problems are common and caution is required. Catheter fragmentation and aspiration therapy is effective for acute pulmonary embolism, is minimally invasive, and should be considered the treatment of first choice.
