RESUMO
Penile amputation is a surgical emergency where practical and timely perioperative management is crucial for ensuring a successful outcome. Tenuous viability of penile and scrotal skin has been well described in the literature, with a putative mechanism attributed to the transection of distal branches of the external pudendal artery. Although the perforasomes critical to penile replantation have been debated, this case report details a patient who successfully recovered sensation and function with minimal necrosis after penile replantation. Surgically, this was facilitated by intentional drain placement, aggressive debridement beyond the zone of injury, and planned redundancies with dorsal artery/vein anastomoses via interposition grafts of the dorsal penile vessels alone.
RESUMO
Traumatic lip amputation is a devastating injury. No other tissue replicates its unique histology, often limiting the reconstructive outcome. Replantation is a technically challenging procedure, requiring extensive postoperative optimization, including systemic anticoagulation, leech therapy, significant blood loss, and antibiosis. Given the rarity of replantation in the context of pregnancy, there are no documented accounts of lip replantation in pregnant patients. We report a case of a 25-year-old pregnant woman who sustained an avulsion injury of the right upper lip from a dog bite. The patient presented with the amputated lip and emergent microvascular replantation was performed. Postoperative course consisted of management of controlled yet significant blood loss through leech therapy and close collaboration with obstetric colleagues. The patient was ultimately discharged with successful cosmetic and functional outcome and, importantly, with maintenance of a healthy pregnancy.
