Relação entre os controles glicêmicos e de pressão arterial com complicações de vitrectomia em pacientes diabéticos

Abstract

Purpose: To evaluate the association between clinical and surgical data of patients with diabetic retinopathy undergoing vitrectomy with postoperative complications. Methods: For 12 months were analyzed patients undergoing diabetic vitrectomy and recorded their glucose and blood pressure controls made before and during surgery. These data were thus associated with retinal hemorrhage and intraoperative complications after 30 days postoperatively as vitreous hemorrhage and retinal detachment. Furthermore, combined with phacoemulsification use of adjuvant bevacizumab silicone oil or gas buffered 12% and the need for surgical re-interventions were evaluated. Results: The study included 29 eyes. The mean age was 54.4 years with a prevalence of left eyes (51.72%) and men (51.72%). The rate of intraoperative retinal haemorrhage was 24.14% of postoperative vitreous hemorrhage was 31.03%, and retinal detachment postoperative was 6.9%. Of patients who had intraoperative retinal hemorrhage were 71.42% with fasting glucose, with 57.14% and 66.66% blood glucose with glycated hemoglobin change, and 50% with high blood pressure. As for those who had complications, 81.82% had fasting glucose, 63.64% blood glucose and glycated hemoglobin changed 70%, and 50% with high blood pressure. These prevalences significantivas not statistically. No patients with elevated pressures developed retinal hemorrhage during surgery (0/13) (P = 0.008). Conclusion: The complications of diabetic vitrectomy had no statistically significant relationship with diabetes or high blood pressure descotrolados near surgery, despite the high prevalence among them. The only relevant finding was the high pressure indices have served as a protective role for active bleeding, which can be placed as coincidence bias.
