Definition: Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Input: Abstract: Three patients with recent stroke underwent carotid endarterectomy 1, 4, and 8 days after the onset of maximal symptoms. In each case, computed tomography (CT) demonstrated recent cerebral infarction and cerebral arteriography showed high grade cervical carotid stenosis. No patient developed worsened neurological symptomatology, intracerebral hemorrhage, or vasomotor paralysis. These results suggest that carotid endarterectomy, if indicated, can be performed safely after acute stroke under certain conditions. These criteria include the following: normal level of consciousness, relatively small cerebral infarction without mass effect on CT, and meticulous control and monitoring of systemic blood pressure during the perioperative period. These initial observations suggest that a specific subgroup of patients with recent cerebral infarction may be able safely to undergo carotid endarterectomy shortly after diagnosis.
Which is the apt title for the abstract? option1: Carotid endarterectomy after recent stroke: preliminary observations in patients undergoing early operation. option2: Complications of transluminal angioplasty [letter]
Output:
Carotid endarterectomy after recent stroke: preliminary observations in patients undergoing early operation.
