Two patients with intraventricular hemorrhage (IVH) were treated by direct removal of their intraventricular hematomas via a high occipital transcortical approach with successful results. This approach lies between the parietooccipital transcortical approach and the occipital transcortical approach. The patients were a 90-year-old woman with idiopathic IVH and a 60-year-old man with hemorrhage caused by bleeding in the thalamus. In both cases, the hematoma was tightly packed in the lateral ventricle. In the former case, the inferior horn of the lateral ventricle was extremely swollen, and the patient was at risk for development of uncal herniation. With the goals of complete elimination of the hematoma in the inferior horn and identification of the source of bleeding, a high occipital transcortical approach was applied, and the hematoma was removed under direct vision. With the patient in the lateral position, a minor craniotomy of approximately 3 cm was performed around the puncture site of the posterior horn (8 cm craniad from the inion and 3 cm lateral from the midline). A 1-cm cortical incision was made and the posterior horn was reached. First, the portion of hematoma at this site was removed, and then the remainder was completely removed from the interior horn and corpus. Using this method, the entire region of the lateral ventricle, including the inferior horn, corpus, and posterior horn, can be covered in a single operative field, and it is also possible to have sufficient working space for the operation.
