Axillary massage induced lateral thoracic artery pseudoaneurysm rupture: Case report.

Introduction And Importance: Massage is a form of health care, but incorrect techniques can potentially harm the human body (Qin et al., 2023 [1]). While there have been no reported cases of lateral thoracic artery pseudoaneurysm and rupture induced by axillary massage, it is important to further explore how to address and prevent such potential risks.

Case Presentation: This case study highlights a rare occurrence where a 61-year-old female patient experienced a lateral thoracic artery pseudoaneurysm and ruptured as a result of an axillary massage. The patient, self-taught in Chinese medicine and massage, regularly rubbed the Jiquan points in her armpits to promote heart health, with each session lasting 30-60 min for two years. She presented with symptoms such as dizziness, palpitations, left armpit pain, and oedema, leading to her admission to a nearby hospital. Despite receiving blood transfusions, her symptoms did not improve, necessitating her to refer to our hospital. A CT angiography scan of her upper limb arteries revealed the presence of a left lateral thoracic artery pseudoaneurysm and rupture, resulting in subcutaneous hematoma in the left axilla, chest, and back. Following angiography, successful embolisation was performed. Three months after surgery, the patient regained full mobility and was free from pain in her left upper limb.

Clinical Discussion: The armpit region contains a high concentration of nerves and blood vessels, making it crucial to have a thorough understanding of its anatomy and to use precise massage techniques. Damage to the axillary arteries can result in severe complications, which can be addressed through either open or endovascular interventional procedures. This article reviews existing literature and guides in managing these specific scenarios.

Conclusion: Caution should be exercised when performing an armpit massage, as a thorough understanding of the anatomy of the axillary area is crucial. Injury to the lateral thoracic artery is a potential risk during axillary massage, and in such cases, endovascular intervention may be considered.
