Fig. 2From: Use of bronchoscopic steam thermal ablation (BTVA) in a clinically compromised patientBTVA plan to treat LB 1 + 2 a-b. After placing an endoscopic catheter, a balloon was inflated in order to occlude the target segment and water heated vapor was delivered, 8.5 cal/g dose, first in LB1 + 2a for 6.1 s. Afterwards the balloon was deflated and the catheter was inserted into the other sub-segmentary bronchus LB1 + 2b for 3.6 s to complete the treatment of LB 1+ 2 a-bBack to article page
