UNASSIGNED: 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.
METHODS: 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.
UNASSIGNED: 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.
CONCLUSIONS: 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.

In this article, we describe the \'Artesian Perforator Concept\', based on the idea that in clinical practice, there are multiple plexuses between perforasomes in addition to the supra-fascial direct and indirect linking vessels that are present within deeper soft tissue, which form part of a deeper vascular reservoir, the equivalent of a vascular \'aquifer\'. We then demonstrate the use of this concept clinically for a 45-year-old male patient with median sternotomy wound dehiscence who was reconstructed using the Internal Mammary Artery Perforator and Lateral Thoracic Artery Perforator flaps.

We report a case of delayed bleeding after video-assisted thoracic surgery (VATS) that was successfully treated with transcatheter arterial embolization. An 81-year-old woman underwent a pleural biopsy via VATS for pleural dissemination of lung cancer. The postoperative course was good, but 8 days later she was hospitalized for swelling in the right axilla and was admitted to our hospital with a diagnosis of delayed postoperative hemorrhage. Gauze compression was performed, and the patient was discharged without exacerbation of hematoma. However, 4 days later, she was hospitalized for rapidly worsening swelling and pain. Chest computed tomography at the time of rebleeding showed an increase in the hematoma and extravasation in the peripheral right lateral thoracic artery. The patient was immediately treated with emergency angiography, and coil embolization was performed. After this treatment, the patient has done well and there has been no subsequent recurrence of bleeding.

Introduction: Pectoralis major myo-cutaneous (PMMC) flap continues to be a widely used tool to reconstruct oral cavity defects. But an unreliable and unstable vascular supply can lead to complications like flap loss, Oro-cutaneous fistula and wound dehiscence. Preservation of the lateral thoracic artery (LTA) has been suggested to improve the vascularity of the skin paddle. The present study aspires to compare the complications and flap related outcomes after preserving or sacrificing the LTA while reconstructing oral cavity defects with bi-folded PMMC flap. Materials and Methods: Retrospective analysis of the data of 61 male patients who were reconstructed with bi-folded PMMC flaps between January 2022 and September 2022 was done. 36 patients were reconstructed using a PMMC flap where the LTA was sacrificed, whereas in 25 patients the LTA was preserved. Data was analyzed in terms of patient factors and flap related complications. Results: The overall complication rate including major/minor complications was 44.26% with flap detachment at 22.95% being the commonest complication observed. 13.11% patients developed an Oro-cutaneous fistula and partial and complete flap loss were seen in 9.83% and 4.91% respectively. LTA preservation was significantly associated with only decreased flap detachment rates (p value < 0.05). No significant association was noticed between other flap related complications and LTA preservation. Conclusion: Reconstructing larger defects with a PMMC flap where the LTA is preserved can help improve the vascularity of the flap and decrease various major/minor flap related complications.

OBJECTIVE: The report describes a bilateral suprascapular artery (SPSA) of atypical origin in coexistence with neurovascular aberrant structures.
METHODS: The variants were identified in a 91-year-old formalin-embalmed male cadaver, derived from a body donation program after a signed informed consent.
RESULTS: The left-sided SPSA emanated from the 1st part of the axillary artery, coursed between the brachial plexus lateral and medial cords, accompanied by the suprascapular nerve, and passed below the superior transverse scapular ligament. Ipsilateral coexisted variants were the lateral thoracic artery multiplication, the subscapular trunk formation, and the musculocutaneous nerve duplication. In the right supraclavicular area, a SPSA duplication was identified. The main artery emanated from the thyrocervical trunk in common with the transverse cervical artery and the accessory SPSA emanated from the dorsal scapular artery. Both SPSAs coursed over the superior transverse scapular ligament, while the suprascapular nerve ran below the ligament.
CONCLUSIONS: The current study reported a bilateral aberrant SPSA, originating from the AA 1st part (left side) and from the dorsal scapular artery (right side), which coexisted with adjacent neurovascular structures\' variants. The left SPSA atypically coursed below the superior transverse scapular ligament. Such an unusual combination of variations, present bilaterally in the current study, may be challenging for radiologists and surgeons.

Pulmonologists must be aware of the possible arterial bleeding even during the removal of a safely inserted drain.

Conventional dynamic contrast enhanced (DCE) magnetic resonance (MR) hardly achieves a good imaging performance of arteries and lymph nodes in the breast area. Therefore, a new imaging method is needed for the assessment of breast arteries and lymph nodes.
We performed prospective research. The research included 52 patients aged from 25 to 64 between June 2019 and April 2020. The isotropic e-THRIVE sequence scanned in the coronal direction after DCE-THRIVE. Reconstructed images obtained by DCE-THRIVE and the coronal e-THRIVE were compared mainly in terms of the completeness of the lateral thoracic artery, thoracodorsal artery, and lymph nodes. We proposed a criterion for evaluating image quality. According to the criterion, images were assigned a score from 1 to 5 according to the grade from low to high. Two board-certified doctors evaluated images individually, and their average score was taken as the final result. The chi-square test was used to assess the difference.
The coronal e-THRIVE score is 4.60, which is higher than the DCE-THRIVE score of 3.48, there are significant differences between the images obtained by two sequences (P = 1.2712e-8). According to the score of images, 44 patients (84.61%) had high-quality images on the bilateral breast. Only 3 patients\' (5.77%) images were not ideal on both sides. The improved method is effective for most patients to get better images.
The proposed coronal e-THRIVE scan can get higher quality reconstruction images than the conventional method to visualize the course of arteries and the distribution of lymph nodes in most patients, which will be helpful for the clinical follow-up treatment.

In a Greek Caucasian male cadaver, a combination of the following arterial variations were observed: an aberrant right subclavian artery originating as a last branch of the aortic arch and coursed posterior to the oesophagus, a right non-recurrent laryngeal nerve, an atypical origin of the left suprascapular artery from the axillary artery, an unusual emersion of the lateral thoracic artery from the subscapular artery and a separate origin of the left thoracodorsal artery from the axillary artery. According to the available literature the corresponding incidences of the referred variants are: 0.7% for the aberrant right subclavian artery, 1.6-3.8% for the origin of the suprascapular artery from the axillary artery, 3% for the origin of the left thoracodorsal artery from the axillary artery and 30% for the origin of the lateral thoracic artery from the subscapular artery. Such unusual coexistence of arterial variations may developmentally be explained and has important clinical significance.

Variations in the branching pattern of axillary artery are observed by many anatomists all over the world. A unique bilateral variation in the axillary artery was observed during the routine dissection of the upper limbs on an approximately 65 year old male cadaver. An abnormal communicative channel was observed between lateral thoracic artery and anterior circumflex humeral artery. It passed between the two roots of median nerve. Arterial anomalies in the upper limb are due to defective remodelling of vascular plexus of the upper limb bud during embryogenesis. Knowledge of variations in axillary artery is quintessential for surgeons, radiologists and anaesthesiologists to avoid treacherous complications during procedures.

Neural and vascular variations in the axilla and upper limb area are usually paired, but coexistence of muscular aberration on top of this is uncommon. The current case report emphasizes on the unilateral coexistence of a three-headed (tricipital) biceps brachii muscle, a two-headed coracobrachialis with an accessory muscle bundle joining the superficial and deep heads of coracobrachialis muscle. On the ipsilateral side of the 72-year-old male cadaver, a connecting branch originated from the musculocutaneous nerve and joined the median nerve after surpassing the accessory muscle bundle. A large diameter subscapular trunk originated from the 2nd part of the axillary artery and after giving off the 1st lateral thoracic artery trifurcated into a common stem which gave off the 2nd and 3rd lateral thoracic arteries, the circumflex scapular artery and a common branch that gave off the 4th and 5th lateral thoracic arteries and the thoracodorsal artery, as the ultimate branch. All lateral thoracic arteries were accompanied by multiple intercostobra- chial nerves. Documentation of such muscular and neurovascular variants and their embryologic origin increases awareness of their potential impact on diagnosis and treatment of upper limb pathology. To the best of our knowledge, the currently reported cadaveric observations seem to constitute a unique finding.
