“…During flap repair, avascular necrosis of the distal flap is the most common cause of surgical failure (Bai et al, 2021;Zhang et al, 2021). Therefore, the most important factor in protecting flap survival is to promote angiogenesis (Zhu X. et al, 2021;Lou et al, 2021).…”

Random flaps are widely used in tissue reconstruction, attributed to the lack of vascular axial limitation. Nevertheless, the distal end of the flap is prone to necrosis due to the lack of blood supply. Notoginseng triterpenes (NTs) are the active components extracted from Panax notoginseng, reducing oxygen consumption and improving the body’s tolerance to hypoxia. However, their role in random flap survival has not been elucidated. In this study, we used a mouse random skin flap model to verify that NT can promote cell proliferation and migration and that increasing blood perfusion can effectively improve the survival area of a skin flap. Our study also showed that the autophagy of random flaps after NT treatment was activated through the Beclin-1/VPS34/LC3 signaling pathway, and the therapeutic effect of NT significantly decreased after VPS34 IN inhibited autophagy. In conclusion, we have demonstrated that NT can significantly improve the survival rate of random flaps through the Beclin-1/VPS34/LC3 signaling pathway, suggesting that it might be a promising clinical treatment option.

“…Results were consistent with those reported by Bai et al, who divided the LTA into three different segments. 17 The mean diameter of the LTA was 1.43 AE 0.15 mm (range 1.23-1.72). The mean length of the LTA from its origin at the DPA until it reached the CB was 68.26 AE 3.12 mm (range 63.15-74.67).…”

Background The cuboid bone (CB) of the foot has been suggested as a potential source of autologous reconstruction of the distal radius (DR). This study sought to examine the feasibility of harvesting the CB as a vascularized bone transfer for DR reconstruction. Purposes We evaluated the feasibility of a vascularized bone transfer of the CB by performing the flap dissection, analyzing its pedicle and demonstrating its perfusion using indocyanine green (ICG) fluorescence angiography. Methods Ten feet from five fresh-frozen cadaver specimens were dissected. The lateral tarsal artery (LTA) mean diameter, length, and emerging point were described. The CB mean length and the mean length of the bone segment harvested were reported. ICG injection was used to demonstrate its blood supply. Results The average length of the pedicle was 68.26 ± 3.12 mm. The mean diameter was 1.43 ± 0.15 mm. The CB had a mean anterior–posterior length of 40.81 ± 5.05 mm. The harvested bone had a mean length of 15.05 ± 2.03 mm. All CBs showed enhancement after ICG injection. Conclusion The CB presented reasonable anatomical similarities with the DR and a long and consistent pedicle with an adequate blood supply observed during ICG injection. Clinical Relevance This study supports the possibility of using the CB as a vascularized bone transfer for autologous reconstruction of the articular surface of the DR. Further study is warranted.

“…While the lateral tarsal and first metatarsal arteries are commonly used as flaps [7][8][9][10], the MTA has received less attention than the other DPA branches and there have been few studies of the anatomical features of the MTA. Ballmer et al (1999) [6] found that the DPA gave two to four branches from its medial side, which were the MTA, and the average diameter at their origin was measured to be 0.4 mm (ranging from 0.2 to 0.7 mm).…”

Missing medial tarsal artery replaced by the anterior medial malleolar artery

The present case report describes an unusual variant of a missing medial tarsal artery (MTA) being replaced by the anterior medial malleolar artery (AMMA). The dorsalis pedis artery (DPA) did not give off any branches to the medial foot. The DPA coursed downward in the foot along with the superficial fibular nerve on the foot dorsum at the lateral side of the first metatarsal bone before entering the sole. In the medial malleolus, the AMMA arose from the anterior tibial artery and then ramified several branches, one of which descended to the medial talus. Thus, the possibility of a missing MTA being replaced by the AMMA should be considered by surgeons and radiologists when various surgeries are performed in the medial tarsal area.
