Factors associated with early and late digital revascularization and replantation failure: a retrospective cohort study
Retrospective cohort published in J Hand Surg Eur Vol (2021)
Abstract
Factors associated with failure of digital revascularization and replantation procedures have been well characterized, but studies have not investigated failures occurring beyond the early postoperative period. A single-centre retrospective chart review included 284 patients (434 digits) who underwent digital revascularization or replantation. Patient-, injury- and surgery-related characteristics were compared among successful procedures, digits that failed while in hospital (early failure), and initially viable digits that failed after hospital discharge (late failure). Overall, 202 patients had successful procedures (71%). There were 51 early failures (18%) and 31 late failures (11%). Crush injuries and vein grafting were associated with early failure only. Complete amputations and leeching were strongly associated with both early and late failure. This study revealed that a substantial proportion of initially viable digits fail after discharge from hospital. Patients with signs of venous congestion may benefit from longer observation periods in hospital to avoid late failure.Level of evidence: IV.

Resumen
In 284 patients and 434 digits, leeching was strongly associated with both early (in-hospital) and late (post-discharge) failure of digital revascularization or replantation. 11% of initially viable digits failed after discharge.
Por qué esto importa para la hirudoterapia
Esta revisión retrospectiva unicéntrica de historias clínicas incluyó 284 pacientes (434 dedos) sometidos a revascularización o reimplante digital, comparando las características relacionadas con el paciente, la lesión y la cirugía entre los procedimientos exitosos, los fracasos tempranos (durante la hospitalización) y los fracasos tardíos (tras el alta). El estudio halló que las amputaciones completas y el uso de sanguijuelas se asociaron fuertemente tanto con el fracaso temprano como con el tardío. Para el dominio de ASH, este estudio documenta el uso de sanguijuelas como un factor presente en un subgrupo de casos de revascularización y reimplante digital en este centro. La advertencia honesta es que el resumen solo reporta una asociación entre el uso de sanguijuelas y el fracaso; no aborda la naturaleza del uso de sanguijuelas ni su papel causal en los desenlaces, y el estudio fue diseñado para identificar factores asociados al fracaso más que para evaluar la terapia con sanguijuelas en sí misma.
