In principle, surgery for acute subdural hematoma (ASDH) involves craniotomy for hematoma removal. Burr hole surgery is not considered a standard procedure due to its limited therapeutic effect; however, it is often performed prior to craniotomy in cases where craniotomy is difficult or in emergency situations. Previous studies reported good outcomes for the use of burr hole surgery alone for removing hematoma. Although some cases of ASDH can be treated with burr hole surgery alone, prognostic factors and indications for surgery are unknown.
In the present case, the patient was elderly, and her medical history made craniotomy difficult. We treated the patient with burr hole surgery alone and achieved a good outcome. The patient’s age, neurological findings on admission, and the nature of the hematoma may have contributed to the favorable outcome. Burr hole surgery is a minimally invasive procedure and may be an option for ASDH patients who are unable to undergo craniotomy. With the aging population, the number of ASDH patients who face challenges in undergoing craniotomy is expected to rise; therefore, further research on minimally invasive surgery for ASDH is necessary.
