Surgical approaches for thoracic outlet decompression in the treatment of thoracic outlet syndrome

Thoracic outlet syndrome (TOS) is a controversial and uncommon syndrome. Three different diagnoses can be made based on the compressed structure: arterial TOS, venous TOS, and neurogenic TOS. Diagnosing TOS, especially neurogenic TOS, remains difficult since a single diagnostic tool does not exist. Although this resulted in a lot of confusion, standardization of care and outcome improved daily care practice measures in the last decade. Current treatment algorithms consist of both conservative and surgical treatment approaches, which should be chosen depending on the type of TOS and extend of the complaints. Surgical treatment of TOS is performed via thoracic outlet decompression (TOD). TOD surgery includes complete resection of the first rib (cartilage to cartilage), transection of the scalene muscles and complete neurolysis/venolysis or arteriolysis. Four different approaches can be chosen for TOD surgery: the transaxillary (TA), supraclavicular (SC), paraclavicular (PC), and infraclavicular (IC) approach. The TA, SC, and PC approach can be used for every form of TOS. However, the PC approach is mostly used for treating venous TOS. The IC approach has no role in treating neurogenic or arterial TOS and is only used for venous TOS. Every approach has its own benefits and limitations and literature does not agree on what approach is best. Therefore, the used surgical approach for TOD should be based on the surgeon\u27s preference and experience. The aim of this review is to present an overview of the diagnostic pathway and provide an in-depth description of the surgical approach in each form of TOS

Interpectoral-pectoserratus plane (PECS II) block in patients undergoing trans-axillary thoracic outlet decompression surgery; A prospective double-blind, randomized, placebo-controlled clinical trial

STUDY OBJECTIVE: To investigate if an interpectoral-pectoserratus plane (PECS II) block decreases postoperative pain, postoperative nausea and vomiting and improves quality of recovery in patients with neurogenic thoracic outlet syndrome (NTOS) undergoing trans-axillary thoracic outlet decompression surgery. DESIGN: A prospective single center double blinded randomized placebo-controlled trial. SETTING: Perioperative period; operating room, post anesthesia care unit (PACU) and hospital ward. PATIENTS: Seventy patients with NTOS, undergoing trans-axillary thoracic outlet decompression surgery. INTERVENTIONS: Patients were randomized to an interventional arm, receiving the block with 40 ml ropivacaine 0.5% (concentration was adjusted if the patient's weight was <66 kg), and a placebo group, receiving a sham block with 40 ml NaCl 0.9%. The interpectoral-pectoserratus plane block was performed ultrasound guided; the first injection below the pectoral minor muscle and the second below the pectoral major muscle. The hospitals' pharmacist prepared the study medication and was the only person able to see the randomization result. The study was blinded for patients, researchers and medical personnel. MEASUREMENTS: Primary outcome parameters were postoperative pain, measured by numeric rating scale on the PACU (start and end) and on the ward on postoperative day (POD) 0 and 1, and postoperative morphine consumption, measured on the PACU and on the ward during the first 24 h. Secondary outcome parameters were postoperative nausea and vomiting, and quality of recovery. MAIN RESULTS: There was no statistically significant difference in NRS on the PACU at the start (ropivacaine 4.9 ± 3.2 vs placebo 6.2 ± 3.0, p = .07), at the end (ropivacaine 4.0 ± 1.7 vs placebo 3.9 ± 1.7, p = .77), on the ward on POD 0 (ropivacaine 4.6 ± 2.0 vs placebo 4.6 ± 2.0, p = 1.00) or POD 1 (ropivacaine 3.9 ± 1.8 vs placebo 3.6 ± 2.0, p = .53). There was no difference in postoperative morphine consumption at the PACU (ropivacaine 11.0 mg ± 6.5 vs placebo 10.8 mg ± 4.8, p = .91) or on the ward (ropivacaine 11.6 mg ± 8.5 vs placebo 9.6 mg ± 9.4, p = .39). CONCLUSIONS: The interpectoral-pectoserratus plane block is not effective for postoperative analgesia in patients with NTOS undergoing trans-axillary thoracic outlet decompression surgery
