 When the cavity was encountered it was due to some compression and dissection of some of the fibrinous deposit in the upper lobe laterally and anterior and this became identified as a very thin layer in one area over this abscess and when it was opened it was quite large and we unroofed it completely and there was bleeding down in the depths of the cavity, which appeared to be from pulmonary veins and these were sutured with a "tissue pledget" of what was probably intercostal nozzle and endothoracic fascia with Prolene sutures.
