Which ICH should be removed?

Clinically if, Patient is showing gradual worsening of neurological deficits. Conscious patient with stable neurological deficits.

Radiologically, Clots more than 10 cubic mm in the thalamus. Clots more than 30 cubic mm in the basal ganglia.

Advantages of Stereotactic Procedure

• Any part of the brain can be reached with unsurpassed accuracy of 0.5 mm.
• Damage to the brain is negligible as compared to open surgery.
• GA is generally not required unless the patient is uncooperative.
• Procedures are generally done in the CT scan room.
• Rate of post-operative complication, like procedure related hemorrhage is less than 1%
• Short hospitalization, saving of the trouble and money.
• Cystic tumors can be aspirated, thus reversing the chances of coning.
• Can be applied vary safely to patients with poor medical grade and patients with advance age.
• In cases of malignant tumors, the pendulum is shifting gradually towards just a biopsy (to know the histology), so that radio and/ or chemotherapy can be planned.
