Background: Lipomas are benign soft tissue tumours, progressively expanding in volume. Beside frequent aesthetic consequences, lipomas can also exert pressure on surrounding tissues and structures.
Materials And Methods: A case of a subpectoral infraclavicular lipoma compressing the axillo-subclavicular neurovascular bundle, produced unilateral brachialgia, thereby simulating a Thoracic Outlet Syndrome. The expansive, but non-infiltrative, nature of the lipoma allowed local excision in the vicinity of the brachial plexus and infraclavicular vascular structures.
Results: Surgical removal of the lipoma resulted in complete remission of symptoms in the left arm and hand.
Conclusions: In the presence of unilateral brachialgia, a subpectoral tumour causing a Thoracic Outlet Syndrome should always be excluded in the absence of other relevant pathology.

Regional Anesthesia with Spontaneous Breathing for Trans-Axillary Surgery in Thoracic Outlet Syndrome: A Retrospective Comparative Study.

Thoracic outlet syndrome (TOS) is an uncommon condition defined by the compression of neurovascular structures within the thoracic outlet. When conservative management strategies fail to alleviate symptoms, surgical decompression becomes necessary. The purpose of this study is to evaluate and compare the efficacy and safety of regional anesthesia (RA) using spontaneous breathing in contrast to general anesthesia (GA) for patients undergoing surgical intervention for TOS.

The unique structure and location of the internal thoracic artery make it an ideal conduit for coronary artery bypass grafting surgery and autologous breast reconstruction. Variants with different characteristics have the potential to impact surgical success. This report presents a female body donor with a novel bilateral variation of the internal thoracic artery.

Background: We have noted that some adolescents and young adults with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) report difficulty with arms-overhead activities, suggestive of brachial plexus dysfunction or thoracic outlet syndrome (TOS). In the TOS literature, diagnostic maneuvers focus on the provocation of upper limb symptoms (arm fatigue and heaviness, paresthesias, neck and upper back pain), but not on elicitation of systemic symptoms.
Objectives: To estimate the proportion of patients with fatiguing illness who experience local and systemic symptoms during a common maneuver used in evaluating TOS-the elevated arm stress test (EAST).

During dissection of a 70-year-old male donor, several anatomical variations were observed, highlighted by a bilateral variant middle scalene muscle in the superolateral thoracic wall. The variant scalene muscle was traced from the transverse processes of cervical vertebrae to the fourth rib with a pronounced fascial slip. The elongated middle scalene muscle was thick in girth and abnormally wide at its insertion (56.

Introduction: There is currently no consensus on the optimal surgical approach for the treatment of venous thoracic outlet syndrome (vTOS). Surgical exposures for vTOS decompression include infraclavicular (IC), supraclavicular (SC), paraclavicular (PC), and transaxillary (AX) approaches. The purpose of this study is to provide a comprehensive review of the outcomes and major complications of these four surgical techniques.
