Success rates of finger revascularization and replantation
Retrospective study published in Plast Reconstr Surg Glob Open (2024)
Abstract
BACKGROUND: Revascularization surgery has been reported to have a higher success rate than replantation due to sufficient venous return. However, in complex cases, success depends on a wide range of indications. This study aimed to investigate success rates in cohorts that included severe cases. METHODS: This single-center, noninterventional, retrospective cohort study included 292 patients (349 digits) who underwent revascularization or replantation at our institution between January 2000 and December 2022. Sex, age, smoking history, comorbidities, affected digit, amputation level, complete or incomplete amputation, type of fracture and mechanism, artery diameter, needle, vein anastomosis in the revascularization subgroup, vein grafting, warm ischemic time, and outcomes were investigated and compared between the revascularization and replantation subgroups of the distal and proximal amputation groups. RESULTS: In the distal amputation group, the arterial diameter in the revascularization subgroup was larger than that in the replantation subgroup (P < 0.05). In the proximal amputation group, the revascularization subgroup had a lower frequency of multiple amputations than the replantation subgroup (P < 0.05). Vein grafts were more frequently used in both revascularization subgroups than in the replantation subgroups (P < 0.05). However, the other injury severity indices were similar, and the success rates were not significantly different between the subgroups. CONCLUSIONS: The revascularization success rate was similar to that of replantation. Vein anastomosis or vein grafting to the veins should be advocated for revascularization in severe cases where skin bridges may not have sufficient venous return.

Resumen
Retrospective analysis of finger revascularization and replantation success rates.
Por qué esto importa para la hirudoterapia
Este estudio de cohorte retrospectivo evaluó las tasas de éxito y los índices de gravedad de la lesión en 292 pacientes (349 dedos) sometidos a revascularización o reimplante de dedos durante un período de 22 años. El resumen enfatiza que el retorno venoso mediante anastomosis venosa o injerto es crucial para el éxito de la revascularización en los casos graves. La congestión venosa es una indicación principal de la hirudoterapia en cirugía reconstructiva, lo cual sugiere una intersección clínica donde las sanguijuelas se utilizan típicamente para rescatar dedos comprometidos. Sin embargo, el resumen se centra estrictamente en los desenlaces quirúrgicos y no menciona en absoluto sanguijuelas, terapia con sanguijuela medicinal ni el secretoma de la sanguijuela. Por lo tanto, su relevancia para ASH es completamente no declarada y solo teórica.
