Randomized Controlled Trial Comparative Study Clinical Trial
Intraoperative cryoanalgesia for postthoracotomy pain relief.
In a randomized study, 63 patients were investigated for the benefits of cryoanalgesia after thoracotomy. Analgesia and its dependent effects such as enhancement of mobility, respiratory function, and reduced need of narcotics were evaluated. ⋯ However, moderate to severe neuralgia was found in a number of patients in the cryoanalgesia group in the late postoperative period. Cryoanalgesia for pain relief after thoracotomy is not recommended.

Fifty-four patients developed severe intercostal neuralgia a few weeks after sternotomy. Immediate relief afforded by parasternal nerve blocks confirmed that the pain derived from scar-entrapped neuromas of the anterior rami of the first 4-6 intercostal nerves in the upper (and mainly left) interchondral spaces after insertion of the sternal wires. Permanent relief (i.e., over 6 months) followed repeated bupivacaine blocks in 57.4% of the patients, phenol blocks in another 22.2%, and alcohol blocks in a remaining 9%. Treatment was successful in 87% of the patients.

The first type of facial pain is of vascular origin. Cluster headache is described as well as its subgroups and carotidodynia. Two organic lesions of the arterial wall can also cause facial pain: dissection of the internal carotid artery and giant cell arteritis. ⋯ Also, local lesions in the cranial nerves can cause facial pain, as well as organic processes of the upper cervical spine and of the occipitocervical transition. The characteristics of facial pain due to eye or ENT and dental lesions are described. So called atypical facial pain occurs quite frequently and mostly affects middle-aged women.

A rare neurovascular complication of a antebrachial arteriovenous fistula in a chronic hemodialysis patient is reported. A large brachial venous pseudoaneurysm caused median neuralgia by direct compression of the nerve. Surgical resection of the pseudoaneurysm resulted in complete relief of neuralgia.
