PURPOSE: To determine whether the use of autologous blood clot seal (ABCS) after biopsy of lung lesions can reduce or prevent pneumothorax. MATERIALS AND METHODS: The authors evaluated 100 patients (63 men, 37 women; age range, 27-78 years) with pleural (n = 23) or deep (n = 77) lesions. Thirty-eight patients had emphysema. Patients were randomly assigned to one of two groups: those in whom the biopsy track was sealed with autologous blood clot (n = 50) and those who did not receive autologous blood clot (n = 50). Biopsy was performed with computed tomographic (CT) guidance and a 19-gauge coaxial system. The autologous blood clot, which ranged from 0.5 to 4.5 mL, was injected while the sheath was being withdrawn. RESULTS:Pneumothorax developed in four of the 23 patients (17%) with pleural lesions and 19 of the 77 patients (24%) with deep lesions. Pneumothorax occurred in four of the 45 patients (9%) who had deep lesions and received autologous blood clot and in 15 of the 32 patients (47%) who had deep lesions and did not receive autologous blood clot (P <.001). In patients with emphysema, pneumothorax occurred in three of the 20 patients (15%) who received autologous blood clot and 10 of the 14 (71%) who did not (P <.001). There were seven large pneumothoraces necessitating treatment; all occurred in patients who did not receive autologous blood clot. CONCLUSION: Plugging of biopsy tracks with ABCS, particularly after biopsy of deep lung lesions, significantly reduced the frequency of pneumothorax-particularly of large pneumothoraces-and, therefore, the need for treatment and the attendant cost.
