The dataset on the characteristics of the intracerebral hemorrhage patients treated by endoscopic hematoma removal or craniotomy

These data present the characteristics of 148 intracerebral hemorrhage (ICH) patients surgically treated. We retrospectively collected data from the medical records of Suwa Red Cross Hospital, including neurological and physiological symptoms, laboratory data, radiological data on admission, complication rate, Glasgow Coma Scale scores on admission or postoperative day 7, and modified Rankin Scale scores at 6 months. Our two articles on the endoscopic hematoma removal and craniotomy for ICH were based on these data [1,2]. This dataset includes detailed laboratory data and radiological features, and it would be useful for reference value for other neurosurgeons or further analysis.


Specifications
Clinical Neurology Specific subject area Neurosurgery Type of data Table  How data were acquired We investigated the medical records of Suwa Red Cross Hospital, and collected data. Data format Raw, and partially averaged. Parameters for data collection From the medical records, we collected objective data, such as laboratory data, physiological data, and neurological symptoms. Radiological information, such as temporal muscle thickness, area [3][4][5][6] , and hematoma volume [7] on the computed tomography (CT) image, could be less objective, so the averages of the two investigators were used. Description of data collection From the intracerebral hemorrhage (ICH) databases of Suwa Red Cross Hospital, we retrospectively retrieved the data from all 148 patients with ICH treated by endoscopic hematoma removal or craniotomy. We collected data regarding neurological and physiological symptoms and laboratory data on admission from the medical records. Radiological information was acquired using CT images. We also investigated the complication rate, the Glasgow Coma Scale on postoperative day 7, and the modified Rankin Scale at 6 months.

Value of the Data
• Data includes detailed characteristics of the ICH patients treated by endoscopic hematoma removal or craniotomy. • This data can be used as a reference value for neurosurgeons when they treat their ICH patients. • The data of temporal muscle thickness/area of the ICH patients can be used to compare healthy patients to investigate the meaning of temporal muscle, focusing on nutrition [ 8 , 9 ] and sarcopenia [10] .

Data Description
The dataset in this table describes the characteristics of the ICH patients. The detailed data are available in the supplementary file.

Experimental Design, Materials and Methods
We investigated our medical record and retrospectively retrieved the data of 148 ICH patients surgically treated from 2009 to 2019. All patients had been independent in activities in daily living before the onset of ICH. The diagnosis of ICH was based on the clinical history and the presence of ICH on CT. The inclusion criteria for the study were; 1) ICH patients in the basal ganglia, subcortex (superficial lobe), or cerebellum; 2) patients indicated for surgery according to the Japanese Guidelines for the Management of Stroke 2009 [11] and 2015 [12] ; and 3) interval between onset and hematoma removal < 24 h. The exclusion criteria were; 1) ICH due to tumor, trauma, aneurysm, arteriovenous malformation, and hemorrhage after infarction; and 2) patients who had thalamic or caudate head hemorrhage with intraventricular hemorrhage treated by flexible neuroendoscope for removing intraventricular hematoma only.
All patients received standard management according to the Japanese Guidelines for the Management of Stroke 2009 [11] and 2015 [12] . First, they were treated with nicardipine to control blood pressure under 140 mmHg. In patients under anticoagulation therapy, prothrombin time was normalized by vitamin K and/or fresh frozen plasma. The criteria for surgical indication were as follows: (1) patients with hematoma ( > 30 mL) in the basal ganglia who were deteriorating neurologically; (2) patients with superficial lobar hemorrhage within 1 cm of the cortical surface and with disturbance of consciousness; and (3) patients with cerebellar hemorrhage > 3 cm in diameter who were deteriorating neurologically or who had brainstem compression and/or hydrocephalus from ventricular obstruction. Rehabilitation and nutritional support were started as soon as possible after surgery, and complications were prevented or treated. Antithrombotic drugs were discontinued postoperatively for several days, depending on the patient's condition and comorbidities.
We collected data about neurological and physiological symptoms, clinical course, and laboratory data on admission. We measured the hematoma volume and the removal rate of the hematoma from the head CT at admission and immediately postoperatively. The hematoma volume was calculated using ABC/2 method [7] . We also investigated the presence of obvious destruction of the pyramidal tract on CT. We checked the primary motor area, corona radiata, posterior limb of the internal capsule, and cerebral peduncle. When one of them was obviously destroyed by the hematoma as a high-density area, we defined obvious destruction of the pyramidal tract; when destruction was equivocal, we defined that the pyramidal tract was not destroyed.
Glasgow Coma Scale scores on day 7, modified Rankin Scale scores at 6 months postoperatively, and postoperative complications were investigated by the medical records, telephonic, or personal interview.
