A 1.1 Kg, four-hour-old, 29-weeks-gestation male patient presented with right upper extremity ischemia secondary to neonatal constriction band syndrome. Emergency constriction band release was deemed necessary to facilitate limb salvage. The anesthetic management of this patient required close communication with the surgical team and meticulous attention to the risks of post-reperfusion syndrome and blood loss in this fragile neonate. Limb salvage was ultimately successful, and the patient demonstrated full neurologic recovery at his two-year follow-up visit.

FtsZ is a bacterial protein that plays a crucial role in cytokinesis by forming the Z-ring. This ring acts as a scaffold to recruit other division proteins and guide the synthesis of septal peptidoglycan, which leads to cell constriction. In its native state, the FtsZ protein from Escherichia coli (EcFtsZ) is a multi-oligomer comprising dimers, trimers, tetramers, and hexamers in a dynamic self-association equilibrium depending on its concentration.

Reperfusion of ischemic skeletal muscle triggers oxidative stress and an immediate inflammatory reaction, leading to damage of distant organs such as the lungs. The inflammatory process implicates numerous mediators, including cytokines, chemokines, and arachidonic acid metabolites. In the orchestration of the inflammatory cascade, a critical role is played by the cluster of differentiation-36 receptor (CD36), a scavenger receptor class B protein (SR-B2) which is expressed on macrophages and functions as a Toll-like receptor coreceptor.

Surgical management of constriction ring syndrome (CRS) is individualised due to the heterogenic presentation of the condition. CRS includes constriction rings, acrosyndactyly, nubbins and short digits. Involvement of more than one limb is common and children often need multiple surgeries.

Case: Vohwinkel syndrome is a rare, inherited condition marked by defective keratinization. The disorder may feature digital constriction bands (pseudoainhum) which can lead to autoamputation. Surgical excision is the only treatment of pseudoainhum; however, it is fraught with recurrence.
