Implantable Doppler flow system: experience with 24 microvascular free-flap operations.
Research article published in Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery (2006)
Abstract
OBJECTIVES: Microvascular reconstruction requires postoperative monitoring to prevent vascular occlusion and flap failure. These methods require skilled personnel and can delay diagnosis and treatment of threatened flap failures. The Cook-Swartz implantable Doppler flow system provides continual feedback on vascular pedicle status, which in turn provides rapid assessment of minute-to-minute changes in flap vasculature that may allow intervention before total vascular occlusion and expeditious reexploration for threatened flap failure, possibly improving flap salvage. STUDY DESIGN AND SETTING: Charts of 24 patients with microvascular free-flap reconstruction and implantation of Doppler flow system at Mayo Clinic Rochester were retrospectively reviewed. Surgical technique and flap outcomes were evaluated. RESULTS: Microvascular reconstruction and implantation of Doppler flow system were successful in all patients. Complications were minimal, and postoperative monitoring system facilitated rapid reexploration when necessary. Flap viability was 96%. CONCLUSION: Doppler flow system is reliable for monitoring minute-to-minute changes in microvascular flap vascular status postoperatively, and allows rapid recognition of complications and facilitating reexploration. This is a valuable, easily mastered tool for microvascular reconstructive surgery. SIGNIFICANCE: May alter postoperative monitoring techniques of microvascular surgeons.

Resumen
Microvascular reconstruction requires postoperative monitoring to prevent vascular occlusion and flap failure. These methods require skilled personnel and can delay diagnosis and treatment of threatened flap failures.
Por qué esto importa para la hirudoterapia
Este estudio revisó retrospectivamente las historias clínicas de 24 pacientes que se sometieron a reconstrucción con colgajo libre microvascular con implantación de un sistema de flujo Doppler, evaluando la técnica quirúrgica y los desenlaces del colgajo. El sistema Doppler implantable proporcionó retroalimentación continua sobre el estado del pedículo vascular y facilitó la reexploración rápida cuando fue necesario, con una viabilidad reportada del colgajo del 96% y complicaciones mínimas. El estudio evalúa una tecnología mecánica de monitorización postoperatoria para reconstrucción microvascular. El resumen no menciona sanguijuelas, hirudoterapia ni ninguna intervención relacionada con sanguijuelas, y su relevancia para la hirudoterapia o el secretoma de la sanguijuela es enteramente indirecta, limitada al contexto clínico general del manejo postoperatorio del colgajo.
