Efficacy of perioperative management for vitrectomy of patients with severe systemic disease

Abstract

Objective To evaluate the efficacy of perioperative management for vitrectomy of patients with severe systemic disease. Methods The clinical data of 21 patients (22 eyes) with severe systemic disease who underwent vitrectomy were retrospectively analyzed. There were 11 patients (12 eyes) with proliferative diabetic retinopathy, 9 patients (9 eyes) with rhegmatogenous retinal detachment, and 1 patient (1 eye) with intraocular lens dislocation. The preoperative visual acuity ranged from hand movement to 0.6.There were 4 patients (5 eyes) with renal insufficiency undergoing renal dialysis, 7 patients (7 eyes) with myocardtal infarction or coronary artery stenosis received cardiac bypass surgery or coronary stent implantation, 2 patients (2 eyes) with severe arrhythmia received cardiac pacemaker implantation or radiofrequency catheter ablation, 5 patients (5 eyes) with cerebral infarction, 2 patients (2 eyes) with hemophilia, and 1 patient (1 eye) with aplastic anemia. For patients with cardiac bypass surgery or coronary stent implantation, anticoagulants were switch to low molecular heparin at 7 days before vitrectomy. For patients undergoing renal dialysis, 0.4 ml low molecular heparin was used during renal dialysis at one day before vitrectomy, protamine and heparin were administered after vitrectomy. Prothrombin complex was infused from 1 day before surgery to 5 days after surgery for Hemophilia B patients. 6 patients (6 eyes)underwent phacoemulsification, and 1 patient (1 eye) underwent ciliary sulcus fixed intraocular lens implantation. 14 patients (14 eyes) underwent silicone oil tamponade, 5 patients (6 eyes) underwent C3F8tamponade. Results The postoperative visual acuity ranged from light perception to 1.0. The vision increased in 18 patients (19 eyes), unchanged in 2 patients (2 eyes), and decreased in 1 patient (1 eye).The retina attached in all eyes postoperatively. The postoperative complications mainly included mild anterior chamber bleeding in 4 patients (4 eyes), severe anterior chamber bleeding in 1 patient (1 eye) , mild retinal hemorrhage in 2 patients (2 eyes), optic disc bleeding in 2 patients (3 eyes), temporary elevation of intraocular pressure in 1 patient (1 eye), and neovascular glaucoma in 1 patient (1 eye). Serum creatinine increased in 1 patient and hypertension in 1 patient within 1 week postoperatively. Conclusions Severe systemic disease is not an absolute contraindication for vitrectomy. Vitrectomy can be successfully performed with better outcomes under the proper perioperative management of systemic disease.
