32.4% (35/108) of patients
86% (30/35) experienced grade 1 (no chest tube required) or grade 2 (8 French pigtail chest tube required, without hospital admission)
No relationship with tumor size or antenna #
Hospital Admission
28% (30/108) of patients
77% (23/30) required less than a 72 hour stay
 No intraprocedural deaths2 serious (Grade 4 or higher) intraprocedural AEs
- 73 yo male developed intraprocedural hemothorax requiring transfusion and thoracotomy

安全性的讨论 30 day mortality rate of 1.9% similar to ablation and surgical literaturePTX rate of 32% is similar to prior MWA and RFA literature
- 40% (14/35) required no chest tube placement
- No relationship with number of antenna
-72% of patients treated safely as an outpatient
- Of the 30 patients that required admission, 47% were discharged within 24 hours and 77% within 72 hours
