Thoracotomy is one of the most painful surgical procedures known. Chronic pain in the postoperative period after thoracotomy is a common complication. Post-thoracotomy pain syndrome (PTPS) is a chronic pain with neuropathic and non-neuropathic components, continuing after 2 months of thoracotomy, causing disability by affecting the daily activities and functions of patients. Patients generally describe neuropathic symptoms such as hyperalgesia, allodynia, hypoesthesia at the site of the incision or related dermatomes. Etiology includes preoperative, intraoperative and postoperative factors. Although the mechanism of PTPS formation is not clear yet, the most common cause is the intercostal nerve injury. PTPS treatment is complex because of the neuropathic component of the pain.The risk of PTPS formation can be reduced by controlling early pain before the onset of the disease.When pain occurs, medical treatments are implemented and also minimally invasive interventional procedures could be performed if necessary.
