Nonreplantable total scalp avulsion reconstruction with acellular biologic matrix
Case report published in J Craniofac Surg (2022)
Abstract
Total scalp avulsion is a significant injury typically occurring as a result of industrial accidents involving high-speed rotary machines. Although ideal, scalp replantation is uncommon secondary to the nature of the injury and lack of viable microvas-cular anastomosis targets. Therefore, these defects are often reconstructed with microvascular free tissue transfer, with or without skin grafting. We present a unique case of a patient with total scalp avulsion achieving complete, stable skin coverage over partially intact periosteum using only spare parts of the amputated scalp as a temporary full-thickness graft and porcine urinary bladder matrix, thus, avoiding significant donor site morbidity or extensive surgery. At 4 years postoperative, the scalp coverage remains stable.

Resumen
Total scalp avulsion deemed nonreplantable reconstructed with acellular biologic matrix as alternative to microsurgical replantation.
Por qué esto importa para la hirudoterapia
This case report presents a patient with total scalp avulsion reconstructed using amputated scalp fragments as temporary full-thickness grafts combined with porcine urinary bladder matrix, achieving complete and stable skin coverage at four years without significant donor site morbidity or extensive surgery. The abstract focuses on the use of a biological matrix for wound coverage in a context where microvascular replantation is uncommon due to the nature of the injury. There is no mention of leeches, hirudotherapy, hirudin, or leech-derived compounds. The article has no direct relevance to ASH's domain.
