Although external landmarks and trajectories for external ventricular drainage have been described for the freehand-guided method, no standard trajectory has been reported for deep-seated intracerebral hemorrhage (ICH). This article presents a freehand-guided catheter insertion technique for deep-seated spontaneous ICH using external landmarks.
Freehand-guided hematoma aspiration using Kocher's point and the external auditory canal as landmarks was performed in 32 patients with a diagnosis of spontaneous ICH in basal ganglia treated between May 2015 and July 2018 at the author's institute.
In computed tomographic images, the mean actual to planned catheter tip distance was 16.1 ± 7.7 mm, the mean right–left deviation was 4.6 ± 5.2 mm, the mean anterior–posterior deviation was 11.1 ± 9.5 mm, and the mean superior–inferior deviation was 8.7 ± 4.4 mm. On largest hematoma slice, the mean distance from hematoma centers to inserted catheter was 9.8 ± 4.9 mm, and the mean horizontal and vertical distances were 4.0 ± 4.7 mm and 7.7 ± 4.8 mm, respectively. In 29 of the 32 patients, all the catheter holes contacted hematomas, whereas in the other 3 patients, 1 or more holes were in contact with brain parenchymal tissue.
For patients with basal ganglia hemorrhage, freehand-guided catheter insertion and hematoma aspiration with subsequent fibrinolysis is a feasible procedure that shortens procedural times. The described technique could be used as an alternative method because it can be performed when the patient is in a critical state without additional equipment.
