Abstract:
Objective To identify the patient-specific and surgery-specific risk factors related to the development of surgical site cranioplasty infection after decompressive craniectomy.Methods A consecutive cohort of 319 patients who had undergone cranioplasty following decompressive craniectomy for stroke or trauma at a single institution from January 2009 to June 2015 was retrospectively established.Logistic regression analysis was performed to predict determinants related to infection following cranioplasty.Results Cranioplasty infection occurred in 11 patients (3.4％).Logistic regression analysis identified that previous temporalis muscle resection (OR=20.21,95％CI:2.09-135.38,P=0.003),preoperative subgaleal fluid collection (OR=34.51,95％CI:2.65-226.39,P=0.001),and operative time (＞150 min) (OR=6.62,95％CI:0.96-37.43,P=0.044) were significantly associated with the development ofcranioplasty infection.Patient age,gender,indications for craniectomy,and time interval between initial craniectomy and cranioplasty were not predictors of the development of cranioplasty infection.Conclusions Long surgical time (＞150 min),presence of preoperative subgaleal fluid collection,and craniectomy with temporalis muscle resection may be risk factors for graft infection after cranioplasty.Surgical techniques should be developed to reduce operative time and avoid temporalis muscle resection when possible.In addition,meticulous dural closure aimed at reducing the formation of subgaleal fluid collection is important for the prevention of graft infections after cranioplasty.
