Is the preoperative MPV value related to early thrombus formation in microvascular anastomosis?
Research article published in Journal of plastic surgery and hand surgery (2016)
Abstract
OBJECTIVE: One of the most common encountered problems in free flap surgeries is anastomotic thrombosis. The mean platelet volume (MPV) may indicate the concentration of intra-platelet proactive substances and the thrombogenic potential of the platelets. MPV is used as a clinical monitoring index in routine blood counts, it has not yet been effectively used in free flap surgery. METHODS: This study evaluates the relationship between the preoperative MPV value and anastomotic thrombus formation during the postoperative 48 hours in 32 free flap operations from September 2013 to September 2014. The mean patient age was 36.75 years. The preoperative MPV value, which was obtained from the complete blood count, was recorded and correlation of MPV and postoperative thrombus formation was investigated. RESULTS: Four anastomotic thrombus were encountered in 34 free flaps during the postoperative 48 hours. Two of them were salvaged by performing thrombectomy and/or administration of i.v. heparin. There was no statistical relationship between MPV value and postoperative thrombus formation during 48 hours follow-up (p = 0.925). CONCLUSION: Even though this study didn't find a correlation between preoperative MPV value and postoperative early anastomotic thrombus, it would be helpful to validate the results using multi-centre and comprehensive studies with larger patient cohorts.

Por qué esto importa para la hirudoterapia
Este estudio examinó si el volumen plaquetario medio preoperatorio (MPV) predice la trombosis anastomótica temprana en 32 operaciones de injerto libre, registrando 4 trombos anastomóticos en las primeras 48 horas postoperatorias (dos salvados mediante trombectomía y/o heparina intravenosa) y encontrando que no existe una asociación estadísticamente significativa entre el MPV y la formación de trombos (p = 0,925). Esto se encuadra perfectamente en el escenario clínico central de la hirudoterapia: la cirugía de injerto libre y microvascular es exactamente donde se utilizan lombrices medicinales para aliviar la congestión venosa y rescatar un colgajo fallido, por lo que cualquier marcador que detecte precozmente el riesgo trombótico complementaría la terapia de lombrices. La honesta advertencia es que esto es un estudio de brazo único pequeño de 32 colgajos con resultado negativo, y los propios autores solicitan una validación multicéntrica más grande; no respalda al MPV como un predictor útil ni evalúa la terapia de lombrices.
