Background: Optimal management of recurrent neurogenic thoracic outlet syndrome (NTOS) remains a considerable challenge.
Objective: To assess the safety and effectiveness of reoperative brachial plexus neurolysis in patients with recurrent NTOS.
Methods: From 2009 to 2019, 85 patients underwent reoperative supraclavicular brachial plexus neurolysis for recurrent NTOS after a previous anatomically complete supraclavicular decompression. Data from a prospectively maintained database were analyzed retrospectively.
Results: The mean patient age at reoperation was 36.9 ± 1.3 (range 15-64) years, 75% were female, and the interval after previous primary operation was 2.5 ± 0.2 years. Intervening injury had precipitated recurrent NTOS in 14 patients (16%), and the mean Disability of the Arm, Shoulder, and Hand (QuickDASH) score before reoperation was 65.2 ± 2.6, reflecting substantial disability. Operative findings consisted of dense fibrous scar tissue surrounding/encasing the brachial plexus. Compared with the previous primary operations, reoperations had a shorter operative time (198 ± 4 vs 161 ± 5 minutes, P < .01) and hospital stay (4.4 ± 0.2 vs 3.6 ± 0.1 days, P < .01), but there were no significant differences in the frequency of prolonged hospitalization (7.1% vs 4.7%), early reoperation (3.5% vs 1.2%), or 30-day hospital readmission (8.2% vs 7.1%). During a median follow-up of 4.8 years, QuickDASH scores improved by 23.3 ± 2.6 (34.2% ± 3.6%; P < .01) and patient-rated outcomes were excellent in 24%, good in 42%, fair in 26%, and poor in 8%.
Conclusion: Reoperative supraclavicular brachial plexus neurolysis is technically challenging but safe and effective treatment for recurrent NTOS, with significant improvements in symptoms and function. Diminishing perineural scar tissue development and avoiding secondary injury would likely decrease the need for reoperations.

Anesthetic management for upper arm amputation in a patient with acute rapid atrial fibrillation and a large thyroid goiter: A case report.

Department of Anesthesiology, Yanbian University Hospital, Yanji, Jilin, P.R. China.
Rationale: Patients with atrial fibrillation and a large goiter have high perioperative risks and often cannot tolerate general anesthesia, making it necessary for us to explore new safe and effective anesthesia methods.
Patient Concerns: The patient presented with atrial fibrillation accompanied by rapid ventricular rate, a thrombus attached to the left atrial appendage, and a massive thyroid goiter compressing the airway.
Diagnosis: After the left humerus fracture surgery, the patient's internal fixation loosened and fractured, accompanied by infection, formation of sinus tracts, and suppuration.
Digital Ischemia Secondary to Ulnar Artery Puncture Successfully Treated by Brachial Plexus Block: A Case Report.
A A Pract

From the Department of Anesthesia, Perioperative and Pain Medicine, Lahey Hospital and Medical Center, Burlington, Massachusetts.
After vascular puncture and catheterization, arteries can have many complications that impede blood flow such as vasospasm, thrombosis, and emboli generation, among other complications. Treatment depends on severity of ischemic symptoms and can range from as mild as applying local heat packs to surgical thrombectomy. We present a case of digital ischemia secondary to vascular puncture that was successfully treated with a supraclavicular nerve block, resulting in the vascular surgery team canceling an emergent surgery.

Brachial plexus root avulsion (BPRA) is often caused by road collisions, leading to total loss of motor function in the upper limb. At present, effective treatment options remain limited. Edaravone (EDA), a substance that eliminates free radicals, exhibits numerous biological properties, including neuroprotective, antioxidant and anti-inflammatory effects.

Background: In patients with breast cancer, prone radiation therapy (RT) has been shown to reduce heart and lung dose. Though prone positioning is routinely used for whole breast RT, its use when treating the regional lymph nodes (RLNs) is not widespread.
Methods: In this phase I-II trial for stage IB-IIA breast cancer treated with lumpectomy or mastectomy, patients received 40.
