Article Abstract
Objectives: The purposes of this study were to identify possible compression points along the transit route of the subclavian artery and to provide a detailed anatomical analysis of areas that are involved in the surgical management of the thoracic outlet syndrome (TOS). The results of the current study are based on measurements from cadavers, computed tomography (CT) scans and dry adult first ribs.
Methods: The width and length of the interscalene space and the width of the costoclavicular passage were measured on 18 cervical dissections in 9 cadavers, on 50 dry first ribs and on CT angiography sections from 15 patients whose conditions were not related to TOS.
Results: The average width and length of the interscalene space in cadavers were 15.28 ± 1.94 mm and 15.98 ± 2.13 mm, respectively. The widths of the costoclavicular passage (12.42 ± 1.43 mm) were significantly narrower than the widths and lengths of the interscalene space in cadavers (P < 0.05). The average width and length of the interscalene space (groove for the subclavian artery) in 50 dry ribs were 15.53 ± 2.12 mm and 16.12 ± 1.95 mm, respectively. In CT images, the widths of the costoclavicular passage were also significantly narrower than those of the interscalene space (P < 0.05). The measurements from cadavers, dry first ribs and CT images were not significantly different (P > 0.05).
Conclusions: Our results showed that the costoclavicular width was the narrowest space along the passage route of the subclavian artery. When considering the surgical decompression of the subclavian artery for TOS, this narrowest area should always be kept in mind. Since measurements from CT images and cadavers were significantly similar, CT measurements may be used to evaluate the thoracic outlet region in patients with TOS.

Background: Despite significant advancements in early detection and treatment, cancer recurrence remains a major challenge, affecting 30-55 % of patients within two years following surgery. Tumor recurrence is commonly classified as local, locoregional, regional or distant, yet a unified consensus on these definitions is still lacking.
Materials And Methods: A systematic review of the recent literature (2020-2024) was conducted in accordance with PRISMA guidelines to collect site-specific recurrence definitions.
[Neurovascular compression syndrome in the upper thoracic aperture region: diagnosis and surgical treatment].

Unlabelled: Neurovascular compression syndrome (NVCS) in the region of the upper thoracic aperture (UTA) occurs due to significant compression of the vascular-nervous bundle (VNB) in narrow anatomical spaces, which are represented by an interscalene space, costoclavicular space and area under the pectoralis minor tendon. Based on the data of traditional clinical and instrumental research methods, it is not always possible to accurately determine the nature and level of damage to the vascular-nervous bundle (VNB), that is often caused by variability of anatomical organization of the peripheral nervous system.
Objective: To identify and describe the specific clinical features of NVCS in the region of UTA and propose an informative instrumental method of diagnosis for development of the optimal surgical treatment algorithm.

The costoclavicular block is a proximal approach for blocking the brachial plexus in the infraclavicular fossa. Whether the costoclavicular block offers advantages over lateral paracoracoid approaches has been debated. However, diaphragm-sparing anesthesia for shoulder surgery has recently reignited interest in the costoclavicular space.

Chemical neurolysis of the brachial plexus and paravertebral space have been sparsely reported. This case involves a patient with refractory pain from stage IV breast cancer, characterized by severe discomfort in the right axilla, shoulder, and pectoral region. A diagnostic block with local anesthetics at T2 and T4 paravertebral spaces and interscalene brachial plexus provided 80% pain relief for 12 hours.

Background: Neurogenic thoracic outlet syndrome (nTOS) of infraclavicular etiology is a complex condition involving the compression of the brachial plexus through the interscalene triangle and costoclavicular, infraclavicular, and pectoralis minor space. New insight into nTOS of infraclavicular etiology and its association with scapular dyskinesia has enabled minimally invasive treatments: endoscopic pectoralis minor release (PMR) and infraclavicular brachial plexus neurolysis. The purpose of this study was to analyze clinical outcomes of this technique compared with historically published outcomes for open first rib resection (FRR) and/or scalenectomy.
