Acute subdural hematoma after aortic surgery: A retrospective comparative study

Abstract

This retrospective study demonstrated that the subdural hematoma group received fewer units of platelets, thus it appears to be important to give platelets appropriately. Strict flow regulation or avoidance of retrograde cerebral perfusion is suggested.

Life-threatening subdural hematoma after aortic valve replacement in a patient with Heyde syndrome: a case report

“…The hemorrhagic disorder associated with Heyde syndrome would enhance massive bleeding which resulted in the formation of the large subdural hematoma with severe midline shift. Subdural hematoma following open-heart surgery is sometimes life-threatening, but early diagnosis and prompt treatment may lead to neurological recovery in many cases [7–10]. Especially in our patient, severe hemorrhagic tendency enhanced by Heyde syndrome led to large subdural hematoma and irreversible neurological deterioration.…”

“…Intracranial hemorrhagic events occurring following open-heart surgery are uncommon but may prove devastating due to enhanced bleeding tendency caused by heparin administration, hypothermia, and postoperative anticoagulation therapy [7–10]. Of these, the incidence of subdural hematoma after open-heart surgery was 0.1% [7].…”

Is subdural hemorrhage after pulmonary endarterectomy underrecognized?

“…Several causes of SDH have been postulated. [11][12][13] SDH after cardiac and aortic surgeries have been reported. 11,12 In a series of patients undergoing aortic surgery, 15% were found to have symptomatic SDH, all of which were managed conservatively.…”

Look before you leap

“…2,9 Interestingly, they cite another study that found increased incidence of SDH in aortic surgery to be associated with decreased administration of platelet volume. 10 There are likely other reasons of which we may be unaware. We would caution against jumping to conclusions and preemptively attributing the increased incidence of SDH to inexperience, because there is no evidence that the duration of circulatory arrest is a consistent metric for this.…”
