Event Description
Weiyi gong, li xu, peng yang, zhengquan yu, zhong wang, gang chen, shiming zhang and jiang wu.Characteristics of delayed intracerebral hemorrhage after ventriculoperitoneal shunt insertion.Oncotarget 8 (2017).Abstract background: delayed intracerebral hemorrhage after ventriculoperitoneal (vp) shunt insertion is rare and has not been well investigated previously.Its characteristics is still unknown.Objective: we reported 12 patients with delayed intracerebral hemorrhage after vp shunt to investigate the potential risk factors and the outcome.Results: 12 patients (1.59%) of all the 754 hydrocephalus had delayed intracerebral hemorrhage after vp shunt insertion.Four patients were women and 8 patients were men, ranging in age from 50 to 76 years.The delayed cerebral hemorrhage from day 3 to day 7 post operation was diagnosed by repeated ct.The delayed intracerebral hemorrhage was significantly related to age, prior craniotomy operation history and manipulation of valve system (3¿7 days).Neither gender sexuality nor potential risk factors for postoperative hemorrhage (including anticoagulation/antiplatelet status, liver disease, diabetes, hypertension), time of shunt attempt affected the happen of delayed intracerebral hemorrhage.Materials and methods: the clinical characteristics including sex, age, anticoagulation/antiplatelet status, liver disease, diabetes, hypertension, craniotomy operation history, manipulation of valve system and time of shunt attempt of 754 patients who were surgically treated of vp shunt at the first affiliated hospital of soochow university between 2007 and 2013 were reviewed retrospectively.The potential risk factors of the delayed intracerebral hemorrhage were statistically analyzed.Conclusions: this study summarizes the presentation and outcome of a series of 12 patients with delayed intracerebral hemorrhage after vp shunt.Age = 60 years, prior craniotomy operation and manipulation of the valve system are statistically significant to the delayed hematoma secondary to vp shunt.Reported event.A (b)(6) year old male underwent a decompressive left frontotemporal craniectomy for hypertensive intracerebral hemorrhage 3 months previously.Ct showed hydrocephalus with interstitial edema capping the frontal horns of the lateral ventricles.Preoperative neurological examination was unremarkable.A vp shunt was placed with a medtronic strata programmable valve system (pressure level, 1.5).A ventricular catheter was inserted into the anterior horn of the right lateral ventricle at the first attempt.Twenty four hours after surgery, ct imaging was normal and the pressure of the left decompressive window decreased.On postoperative day 3, the pressure of decompressive window increased and the patient became unconscious.Emergent ct showed a large hematoma along the path of the catheter associated with an appreciable intraventricular hemorrhage.Unfortunately, the patient died suddenly before the evacuation of the hematoma.
