Abstract. Craniotomy is frequently used for the treatment of acute subdural hematoma; however, it the procedure exhibits a high mortality rate. Preoperative trepanation and drainage in an emergency ward may reduce intracranial pressure, shorten operation time and lower patient mortality, and is thus applicable to the treatment of acute subdural hematoma. The present study reports the cases of two elderly patients that benefitted from trepanation and drainage of an acute subdural hematoma. In each case, the family members of the patients refused to consent to a craniotomy; thus, burr-hole drainage was selected as an alternative option for relieving intracranial pressure. The risks require careful evaluation when considering whether trepanation with drainage is an option for a patient. Following treatment, the two cases were cured and discharged on days 48 and 18 after admission, respectively. The present case studies indicate that trepanation with drainage may be a promising approach for reducing craniotomy-associated mortality and closely monitoring condition variation in elderly patients. Following trepanation with drainage, certain patients do not undergo a craniotomy.
IntroductionAcute subdural hematoma is a major life-threatening condition with a mortality rate of 60-80% (1). Subdural hematomas require immediate and aggressive treatment. The main surgical approach is to perform a craniotomy, which involves removing part of the skull, followed by drainage of the hematoma and reattachment of the skull fragment (2). Decompressive craniectomy also involves removing part of the skull to relieve intracranial pressure; however, the part of the skull that is removed is not generally replaced (2). Although craniotomies and craniectomies are frequently used for the treatment of acute subdural hematomas, a major limitation of their use is that these surgical techniques are associated with high mortality rates (3,4). Preoperative trepanation and drainage, in which a burr hole is created in the skull to reduce pressure, may improve surgical outcomes or, in some cases, reduce the need for follow-up surgical care (5). This approach may be particularly valuable for patients who present with comorbidities or cannot endure highly invasive surgical procedures. In the present study, two cases of elderly patients with acute subdural hematomas treated by preoperative trepanation and drainage are reported.
Case reportsCase 1. An 86-year-old male patient developed a sudden headache followed by nausea and vomiting with gradual loss of consciousness. In transit to the Shenyang General Hospital (Shenyang, China), the patient developed cerebral herniation with right and left mydriases of 6.0 mm and 2.0 mm, respectively. The patient was initially admitted to the Emergency Department for acute subdural hematoma and later transferred to the intensive care unit of the Neurological Department. The patient was deeply comatose at the time of admission with a Glasgow Coma Scale (GCS) score of 5, with no eye movement or light reflex. The left p...
