Hypertensive intracerebral hemorrhage

High blood pressure is one of the Spontaneous Intracerebral Hemorrhage Risk Factors.

Optimal recovery from intracerebral hemorrhage was observed in hypertensive patients who achieved the greatest SBP reductions (≥20 mm Hg) in the first hour and maintained for 7 days 1).

Hematomas within the basal ganglia comprise 60% of all cases with hypertensive intracerebral hemorrhage, and these cases have a particularly high morbidity and mortality despite optimized treatments 2).

Dennis MS et al. have reported that the one-year survival rate of patients with these hematomas is only 38% 3) and that most survivors are disabled 4).

Clinical data of 184 patients with HICH in the hospital from January 2019 to May 2021 were analyzed retrospectively. The patients were divided into mini-open craniotomy group and neuroendoscopic-assisted group. The operation time, hematoma clearance rate, intraoperative blood loss, neurological function recovery, and postoperative mortality of the two groups were compared by retrospective analysis.

Results: The operation time and intraoperative blood loss in the mini-open craniotomy group were more than those in the neuroendoscopic-assisted group, but there was no significant difference between the two groups. There was no significant difference in hematoma clearance rate between the two groups, but for the rugby hematoma, the hematoma clearance rate in the neuroendoscopic-assisted group was higher than in the mini-open craniotomy group, the difference was statistically significant. Within 1 month after the operation, there was no significant difference in mortality between the two groups. 6 months after the operation, there was no significant difference in the recovery of neurological function between the two groups.

Conclusion: Neuroendoscopic-assisted and mini-open craniotomy for the treatment of HICH has the advantages of minimal trauma with good effects, and its main reason for short operation time, reduced bleeding, and high hematoma clearance rate. Although the two surgical methods can improve the survival rate of patients, they do not change the prognosis of patients. Therefore, the choice of surgical methods should be adopted based on the patient's clinical manifestations, hematoma volume, hematoma type, and the experience of the surgeon 5).

From February 2013 to November 2018, 60 patients diagnosed as basal ganglia ICH were divided into the filled type hematoma expansion group (FTE group) and the expanded type hematoma expansion group (ETE group). we performed follow-up CT and three-dimensional reconstruction for the patients and compared the hematoma before and after the expansion of size and extent.

The regression analysis showed that the irregular sign (odds ratio, 3.64; 95 % CI, 1.46-9.12), black hole sign (odds ratio, 3.85; 95 % CI, 1.40-10.60), blend sign (odds ratio, 2.86; 95 % CI, 1.03-7.95), and early use of dehydration (odds ratio, 4.59; 95 % CI, 1.59-13.19) were possible risk factors for the ETE group, while the high systolic blood pressure (odds ratio, 1.51; 95 % CI, 1.04-2.30), early use of dehydration (odds ratio, 3.27; 95 % CI, 1.10-9.69) and low density low-density band (odds ratio, 4.52; 95 % CI, 1.54-13.28) were possible risk factors for the FTE group.

The irregular sign, black hole sign, blend sign and early use of dehydration may be the main risk factors for hematoma expansion group, whereas early use of dehydration, high systolic blood pressure, and low-density band may be the main risk factors for hematoma expansion 6).

96 HIH patients were performed the craniotomic hematoma dissection (CHD) and the hematoma-cavity drilling drainage (HCDD), respectively. Meanwhile, the intracranial pressure and mean arterial pressure of each patient were continuously monitored for 7 days, the postoperative 1st, 3rd, 7th and 14th-day average flow velocities and pulsatility indexes of the bilateral middle cerebral arteries were monitored. CHD exhibited the significant difference in the long-term quality of life (ADL classification 6 months later) of patients with hematoma >50 ml than HCDD; furthermore, the postoperative 1st, 3rd, 7th and 14th-day TCD parameter analysis revealed that CHD exhibited better results in relieving the intracranial pressure and improving the cerebral blood flow than HCDD, and the postoperative ICP and MAP monitoring towards all patients could effectively control the blood pressure and prevent the further bleeding. The patients with hematoma >50 ml should choose CHD, and all HIH patients should be routinely performed the ICP and MAP monitoring 7).
