Latissimus dorsi (LD) is one of the most commonly used muscles for coverage of moderate-to-large-sized defects post-tumour excision or trauma.
Seroma (21%–79%) is the most common donor site complication after LD muscle harvest. Other common complications include haematoma, skin margin necrosis and contour deformity. Rarely, brachial plexus injury and lumbar hernia are also reported.
Pneumothorax following LD harvest is a potential and probably an underreported complication., We report two patients who developed pneumothorax after raising the flap. Both patients sustained Gustilo–Anderson type III B lower limb fracture. There were no pre-operative symptoms or signs suggestive of chest trauma in either of them. They underwent debridement, skeletal stabilisation with external fixator and microvascular LD flap cover. LD muscle was raised in a standard manner after infiltrating local anaesthetic solution over the back. After completion of the muscle harvest, intermittent quilting sutures were taken on the back to reduce the dead space and prevent seroma formation. Intra-operative and immediate post-operative periods were uneventful. However, on the second post-operative day, both the patients complained of tightness of the chest and difficulty in breathing. There was decreased air entry on the donor side. X-ray revealed pneumothorax with collapse of ipsilateral lung. Emergency intercostal drain (ICD) was put. Chest physiotherapy with incentive spirometer was started. The pneumothorax resolved and lung expanded fully with the treatment. ICD was removed after 48 h.
Pneumothorax is always a possible complication during chest wall and breast surgeries. Infiltration of local anaesthesia with adrenaline requires multiple pricks, and in thin built patients, it may lead to inadvertent injury to the pleural cavity.,, It can also occur while accessing a jugular/subclavian intravenous line during these surgeries. Further, the technique of quilting sutures for reducing dead space can cause this injury. Finally, pneumothorax can also occur during use of electrocautery for dissection of the muscle from posterior chest wall.
In our cases, the most probable cause for pneumothorax was injury while infiltrating local anaesthetic solution. This risk was avoided using blunt tip infusion cannula for infiltrating local anaesthetic solution. Furthermore, quilting sutures should be taken by avoiding the intercostal spaces. Electrocautery should be used carefully when dissecting the muscle off the posterior chest wall.
Awareness of this rare and probably underreported complication can help in avoiding injury to the pleura during flap harvest.
