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

This single-centre retrospective chart review included 284 patients (434 digits) who underwent digital revascularization or replantation, comparing patient-, injury-, and surgery-related characteristics among successful procedures, early failures (in hospital), and late failures (after discharge). The study found that complete amputations and leeching were strongly associated with both early and late failure. For ASH's domain, this study documents leeching as a factor present in a subset of digital revascularization and replantation cases at this centre. The honest caveat is that the abstract reports only an association between leeching and failure; it does not address the nature of leeching use or its causal role in outcomes, and the study was designed to identify factors associated with failure rather than to evaluate leech therapy itself.
