Abstract WP365: Role of Enhanced CT Findings in Endoscopic Surgery for Intracerebral Hematoma
Objective: In our institute, endoscopic aspiration of hematoma is often performed for acute treatment of intracerebral hematoma (ICH). In some cases, hemostasis is technically difficult to perform during endoscopy, and post-operative hemorrhage may occur. We examined the association between perioperative complications associated with endoscopic surgery for acute ICH, and radiological findings on enhanced computed tomography (CT).
Methods: Subjects were 471 patients diagnosed with hypertensive ICH who had been admitted and treated in our institute within 72 hours from onset, between 2012 and 2015. Enhanced CT imaging was performed at admission, and radiological enhancement signs (RES) were defined as CT angiography spot signs in the arterial phase, or contrast extravasation in the parallel phase. RES-positive subjects were grouped and compared with an equal number of RES-negative subjects, and the association between perioperative complications and RES was analyzed.
Results: The RES-positive group included 39 subjects; endoscopic surgery was performed in 16 of the 39 subjects. Postoperative hemorrhage occurred in 6 of the 16 subjects. No hemorrhagic complications were found in the RES-negative group. Follow-up CT after 24 hours showed hematoma expansion in 20 of 26 subjects in the RES-positive group and in only 1 of the 39 subjects of the RES-negative group. Statistical analyses showed that the RES-positive group had a significantly shorter duration between the onset of ICH and CT scan and significantly larger hematoma volume, compared with the RES-negative group. Multivariate analysis identified the presence of RES as a significant risk factor of postoperative hemorrhage or hematoma expansion on follow-up CT.
Conclusion: CT angiography spot signs or contrast extravasation positive signs were observed with a shorter duration between ICH onset and CT scan, and larger hematomas. These signs may be an important predictive factor for hematoma expansion, as well as a significant risk factor of postoperative hemorrhage after endoscopic surgery for ICH.
