Fatal cerebral swelling immediately after cranioplasty: A case report.

ABSTRACT: Cranioplasty is a standard neurosurgical procedure which is performed after decompressive craniotomy. Fatal complications associated with this procedure are not well documented. Here, we report a case of fatal cerebral swelling after cranioplasty and discuss the possible mechanism of this complication.A 64-year-old man was admitted with the diagnosis of cerebral hemorrhage, and emergency surgery for hemorrhage removal and decompressive craniotomy were performed. One month after surgery, cranioplasty was performed using a titanium mesh plate. Sixteen hours after the surgery, the patient became comatose with bilateral dilated pupils followed by blood pressure lowering. Computed tomography of the brain showed bilateral massive cerebral edema. The titanium mesh plate was immediately removed, however, the patient's neurological condition did not recover and he died 7 days after the surgery. We speculated that the negative pressure difference and increase in cerebral blood flow after cranioplasty may have attributed to the fatal cerebral swelling.Fatal cerebral swelling after cranioplasty is a rare but devastating complication. Although it is rare, neurosurgeons should keep in mind that this fatal complication can follow cranioplasty.

Project description:Background: Cerebral infarction is a rare neurological complication of Kawasaki disease (KD) and occurs in the acute or subacute stage. There have been no reported cases of late-onset fatal cerebral infarction presenting over 1 year after the onset of KD. Case Presentation: A 5-month-old male patient with KD received timely intravenous immunoglobulin therapy; however, extensive coronary artery aneurysms (CAA) and coronary artery thrombosis (CAT) developed 1 month later. Anticoagulation and thrombolytic agents were suggested, but the child's parents refused. Fifteen months after KD onset, an attack of syncope left him with left hemiplegia; brain computerized tomography (CT) scans revealed cerebral infarction of the right basal ganglion without hemorrhage. Magnetic resonance angiography (MRA) revealed severe stenosis of the right middle cerebral artery, and a series of tests were performed to exclude other causes of cerebral infarction. Considering the cerebral infarction and CAT, combination therapy with urokinase and low-molecular-weight heparin (LMWH) was initiated within 24 h of syncope onset, together with oral aspirin and clopidogrel. Five days later, his clinical symptoms partially regressed and he was discharged. Unfortunately, 5 days after discharge, his clinical condition suddenly deteriorated. Repeat brain CT showed hemorrhagic stroke involving the entire left cerebral area, in addition to the previous cerebral infarction in the right basal ganglion, with obvious secondary cerebral swelling and edema, which might have been caused by previous thrombolysis. Severe cerebral hernias developed quickly. Regrettably, the patient's parents abandoned treatment because of economic factors and unfavorable prognosis, and he died soon after. Conclusions: Cerebral infarction and cerebral artery stenosis can develop late, even 1 year after the onset of KD. Pediatricians should be aware of the possibility of cerebrovascular involvement in addition to cardiac complications during long-term follow-up of KD patients. Prompt anticoagulation therapy and regular neuroimaging evaluation are essential for the management of patients with KD with giant CAA and/or CAT.
