Intra-pleural Instillation of Autologous Blood - Fine-tuning Techniques for Better Success Rate: Two Case Reports.

In the past, many case series have reported the effectiveness of autologous blood patch pleurodesis (ABPP) in recurrent secondary spontaneous pneumothorax (SSP), particularly in those who were unfit for surgery. We describe two cases of persistent air leak in pneumoconiosis and pulmonary fibrosis with bronchiectasis, whereby the techniques employed had improved the success rate of ABPP. The determining factors that lead to the success of ABPP were determined by the volume of autologous blood instilled, Trendelenburg position post instillation, and early chest physiotherapy with mobilisation by application of pneumostat.
