The Kakarla Classification was published in 2008 by Kakarla et al. [^1] and is used for the classification of the positional location of external ventricular drains into three different grades.

Classification

Kakarla Grade	Position Description	EVD Position
Grade I	Optimal Position	Ipsilateral frontal horn as well as the tip of the third ventricle.
Grade II	Suboptimal position in non-eloquent brain tissue	Contralateral lateral ventricle, corpus callosum or interhemispheric fissure.
Grade III	Suboptimal position in eloquent brain tissue	brainstem, cerebellum, internal capsule, basal ganglia, thalamus, occipital cortex, basal cisterns.
