Use of nailfold capillaroscopy for the assessment of patients undergoing digit replantation
Methodology study published in Jt Dis Relat Surg (2024)
Abstract
OBJECTIVES: In this study, we aimed to evaluate microvascular changes using nailfold capillaroscopy in patients who underwent digit replantation and revascularization. PATIENTS AND METHODS: A total of 46 patients (34 males, 12 females; mean age: 45.8±17.6 years; range, 18 to 75 years) who underwent replantation or revascularization procedures between February 2012 and May 2023 were retrospectively analyzed. Nailfold capillaroscopy images were assessed for various parameters including capillary count, diameter, dilatation, presence of giant capillaries, capillary disarrangement, microhemorrhages, neoangiogenesis, subpapillary plexus appearance, crossing capillaries, tortuosity, and microaneurysm. We investigated the association between microvascular alterations and clinical outcomes. RESULTS: Of 46 patients, 25 patients underwent replantation and 21 patients underwent revascularization. Significant microvascular changes, including subpapillary venous plexus, microvascular enlargement, microhemorrhages, neoangiogenesis, and tortuosity were observed in replantation patients (p=0.000b, p=0.020, p=0.021b, p=0.001, and p=0.004, respectively). However, these changes were not significant in revascularization patients. Revascularization patients exhibited an increase in capillary diameter and disarrangement (p=0.019 and p=0.016b, respectively). A significant negative correlation existed between digital nerve repairs and microvascular enlargement in replantation patients. Hyperesthesia was significantly correlated with neoangiogenesis and capillary disarrangement, while a statistically significant positive relationship was found between subpapillary venous plexus and patient satisfaction in replantation patients. CONCLUSION: Our study showed that replantation patients who underwent two nerve repairs exhibited a well-regulated microvascular tone. However, we did not observe a statistically significant relationship between the number of nerve repairs and cold intolerance. Based on these findings, we highlight the potential of nailfold capillaroscopy in detecting microvascular changes following replantation and revascularization, which may contribute to a better understanding of the etiology of neurovascular complications.

Resumen
Methodology study of nailfold capillaroscopy as assessment tool for patients undergoing digit replantation.
Por qué esto importa para la hirudoterapia
Este estudio retrospectivo analizó a 46 pacientes sometidos a reimplante o revascularización digital, utilizando capilaroscopia del pliegue ungueal para evaluar los cambios microvasculares posoperatorios. Los hallazgos significativos en los pacientes con reimplante incluyeron plexo venoso subpapilar, agrandamiento microvascular, microhemorragias, neoangiogénesis y tortuosidad, mientras que los pacientes con revascularización mostraron aumento del diámetro capilar y desorganización. El resumen no menciona sanguijuelas, hirudoterapia, hirudina ni ninguna intervención derivada de sanguijuelas. No existe una conexión defendible con el ámbito de ASH según el resumen proporcionado; el estudio se centra enteramente en la evaluación microvascular mediante capilaroscopia tras cirugía reconstructiva de la mano.
