Limb lymphedema is a chronic progressive disease of the lymphatic system that seriously affects the physical and mental health of patients. Supermicrosurgical lymphovenous anastomosis (LVA) can significantly improve the symptoms of early lymphedema and is regarded as a promising therapeutic option. However, this technology also faces many challenges, with only about 15% of patients receiving treatment each year, and 30% of patients progressing to refractory edema. The reported treatment efficacy vary greatly among different institutes. In this article, we review the development history, treatment status, and challenges faced by supermicrosurgical LVA in limb lymphedema, providing reference for clinical practice.

Biodegradable magnesium (Mg) materials offer significant advantages in trauma care due to their degradable nature and superior mechanical properties. This study reports the first successful use of degradable Mg clips in damage control surgery for pelvic fractures, addressing challenges associated with severe hemorrhage and high mortality rates (30–70%). A 57-year-old male patient with pelvic fractures and traumatic shock underwent open reduction and internal fixation with Mg clips. At a six-month follow-up, imaging confirmed fracture healing, clip degradation, and no signs of rebleeding or infection, highlighting their effectiveness in precise hemorrhage control. Unlike traditional titanium clips, Mg clips degrade over time, eliminating the need for removal and reducing infection risks. This innovative approach combines Mg clips with conventional gauze packing, offering a more effective and safer alternative for managing pelvic trauma. Future large-scale clinical trials are necessary to validate these findings and establish Mg clips as a global standard for pelvic fracture treatment. Their portability and functionality hold promise for advancing emergency trauma care.
