Among multiple causes of tracheobronchial rent, most common is iatrogenic factor. Whenever there is surprise evidence of bronchial wall tear while doing lung surgery, tracheal tube extubation and postoperative management pose a challenge. We report a 16-year-old girl, weighing 27kg, a case of pulmonary Koch's who presented with hydropneumothorax on left side. She had a prolonged course on mechanical ventilation, was gradually weaned off and extubated in intensive care unit (ICU) with implantable cardioverter defibrillator (ICD) in-situ. However, chest X-ray continued to show loss of bronchovascular markings and high-resolution computed tomography (HRCT) thorax revealed multiple cavitatory lesions, hydropneumothorax from upper to lower lobe, ground glass opacities on left side and mediastinal shift towards right side. Hence, she was posted for left lung decortication. Decortication was done using one lung ventilation protocol with 28 Fr left sided double-lumen endobronchial tube (DLT). While checking for leaks before closure, it was noted that exhaled tidal volume was unacceptably low and a rent on left main bronchus of around 2x2 cm with scarred borders was detected. The rent was repaired with tissue patch suturing by the surgeons. After the procedure, DLT was exchanged with endotracheal tube (ETT) no 6. Patient was managed with elective ventilation post-operatively in ICU for 48 hours and extubated uneventfully. A vigilant monitoring of vital parameters and close communication with surgeons is important for detecting and managing any perioperative complication during lung surgery. Elective ventilation could play a significant role for healing a big rent in trachea-bronchial area.
