Brief Summary:
The project involves prospectively randomizing patients to either routine carotid shunting or selective carotid shunting during Carotid endarterectomy (CEA) under general anesthesia (GA) to see the difference in post-op complications and occurence rates. Patients will be randomized to Routine shunt vs selective groups.

Condition or disease Intervention/treatment Phase
Stenoses, Carotid Artery Procedure: Carotid endarterectomy with routine shount Procedure: Carotid endarterectomy with selective shunt Not Applicable

Detailed Description:

The significance extends to all surgeons who perform Carotid endarterectomy because of their desire to improve patient care by decreasing the overall perioperative complication rate of the procedure by selectively not shunting those patients who ideally do not require it and thus eliminating the attendant morbidity associated with it.

The hypothesis is that there will be no difference in patient outcomes (death, minor strokes, major strokes, transient ischemic attack (TIA)) for patients undergoing a Carotid endarterectomy with a SP of > 50 mm Hg using selective shunting.Patients will be randomized to Routine shunt vs selective groups. In Selective shunt, there will be subgroup analysis to measure % stenosis if the systolic pressure is < 40mmHg calling it as Shunt group. All patients in the study, irrespective of treatment group will be followed post-operatively from 24 hours to 30 days. The patient will be monitored and the following outcomes documented - death, minor stroke, major stroke, trans-ischemic attack (TIA).

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 200 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Selective Shunting in Appropriately Selected Patients Undergoing Carotid Endarterectomy Based on Stump Pressure
Study Start Date : December 2006
Actual Primary Completion Date : June 2009
Actual Study Completion Date : June 2009

Arm Intervention/treatment
Active Comparator: Routine Shunt
These patients are called routine as the routine method of carotid endarterectomy is used.
Procedure: Carotid endarterectomy with routine shount
Active Comparator: Selective Shunt
These patients are selectively used for shunting or not shunting based on systolic pressure < 40mmHg. This group is further used as subgroup analysis.
Procedure: Carotid endarterectomy with selective shunt

Primary Outcome Measures :
  1. Overall Perioperative Complications Between Selective vs. Routine Shunting. [ Time Frame: Within 30 days of enrollment ]
    perioperative complication included at least one of transient ischemic attack (TIA), hemorrhage, myocardial infarction [MI], or asymptomatic carotid thrombosis or congestive heart failure.
