A hypeensive individual had a sudden headache and became unconscious within a few minutes. On regaining consciousness, there was complete flaccid hemiplegia with no involvement of upper face, absence of tendon reflexes and a positive Babinski sign. Which one of the following aeries could have ruptured :
Correct Answer: Lateral striate branch of middle cerebral
Description: Answer is A (Lateral striate branch of middle cerebral): This is a case of hypeensive intracerebral haemorrhage affecting the basal ganglia. Basal ganglia is supplied through medial and lateral striate branches of middle cerebral aery. Lateral striate branch of middle cerebral aery is thus the site of rupture Hypeensive hemorrhage almost always occurs while the patient is awake and sometimes when stressed. It generally presents as severe headache along with abrupt onset of focal neurological deficit. The focal deficit typically worsens steadily and is associated with a diminishing level of consciousness and signs of increased ICP, such as headache & vomiting. The focal neurological signs vary according to the site of the hemorrhage Basal ganglia Thalamus Pons Cerebellum Aeries involved Aeries involved Aeries involved Aeries involved Medial & lateral striate branches of Middle cerebral aery.
