The Use of Thoracic Segmental Spinal Anaesthesia for Thoracoscopic Diaphragmatic Hernia Repair in an Adult With Cardiac Compromise.

Morgagni hernias are uncommon diaphragmatic defects and are commonly found incidentally as a congenital defect. Acquired Morgagni hernias have been documented in the pediatric population, making them extremely uncommon. Thoracic segmental spinal anesthesia (TSSA) may be used as a successful substitute for general anesthesia, especially in cardiovascularly compromised patients like our patient who had heart failure with reduced ejection fraction (HFrEF), and this is one of the very few documented cases of acquired Morgagni hernia laparoscopic repair surgery done by this anesthesia method. An 80-year-old woman presented with a complaint of left lower chest and left upper quadrant pain. Acute coronary artery syndrome was ruled out. She underwent a coronary artery bypass graft in 2009, complicated two months later by mediastinitis, which is believed to be the cause of the acquired diaphragmatic defect in our patient. Chest and abdominal CT showed a large anterior Morgagni-type diaphragmatic hernia, in which the left hemithorax and anterior mediastinum were both occupied by a herniated transverse colon. Under regional anesthesia, which was done by injecting anesthesia in the spinal space between thoracic spinal vertebrae T8 and T9 and second injections in the epidural space at the level between thoracic epidural T9 and T10, which is neuraxial anesthesia. The repair of the diaphragmatic hernia was done by suturing the mesh into the proper position. We report the first known case of laparoscopic repair of a Morgagni hernia in an adult patient with HFrEF and other comorbidities.
