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.

BACKGROUND: One promising surgical treatment of lymphedema is the VLNT. Lymph nodes can be harvested from different locations; inguinal, axillary, and supraclavicular ones are used most often. The aim of our study was to assess the surgical anatomy of the lateral thoracic artery lymph node flap.
METHODS: In total, 16 lymph node flaps from nine cadavers were dissected. Flap markings were made between the anterior and posterior axillary line in dimensions of 10 × 5 cm. Axillary lymph nodes were analyzed using high-resolution ultrasound and morphologically via dissection. The cutaneous vascular territory of the lateral thoracic artery was highlighted via dye injections, the pedicle recorded by length, and diameter and its location in a specific coordinate system.
RESULTS: On average, 3.10 ± 1.6 lymph nodes were counted per flap via ultrasound. Macroscopic inspection showed on average 13.40 ± 3.13. Their mean dimensions were 3.76 ± 1.19 mm in width and 7.12 ± 0.98 mm in length by ultrasonography, and 3.83 ± 2.14 mm and 6.30 ± 4.43 mm via dissection. The external diameter of the lateral thoracic artery averaged 2.2 ± 0.40 mm with a mean pedicle length of 3.6 ± 0.82 cm. 87.5% of the specimens had a skin paddle.
CONCLUSIONS: The lateral thoracic artery-based lymph node flap proved to be a suitable alternative to other VLNT donor sites.

Anatomic variations of axillary artery branches are commonly encountered during radiological investigation and surgical operations. Their existence can confuse interpretation of radiological results and lead to undesired complications during surgery. In this report authors describe a rare case of a subscapular arterial trunk that gave origin to thoracodorsal, circumflex scapular, posterior humeral circumflex, and lateral thoracic artery. Such a variation might cause undesired sequelae during trauma management and a variety of common flap harvesting operations including latissimus dorsi, scapular and parascapular flaps. Furthermore it presents embryological interest as it gives insight to embryologic development of axillary area.

The thoracodorsal artery perforator flap is a versatile flap for the reconstruction of various soft tissue defects. Several anatomical variations of thoracodorsal artery have been described and an \"accessory thoracodorsal artery\" which has a separate and direct origin from the axillary artery has been reported. In this report, we describe a very unusual direct cutaneous perforator, which ran in a subfascial course above the latissimus dorsi muscle and was found to originate directly from the axillary artery. Based on these findings, surgeons should be aware of the possible existence of this unusual anatomical variation during surgery to avoid missing this perforator.
