EFFECTIVENESS OF CAROTID ARTERY STENTING IN PATIENTS WITH CAROTID ARTERY STENOSIS

Abstract

Objective: To determine the effectiveness of carotid artery stenting in patients with carotid artery stenosis.
Study Design: Prospective cohort study
Place and Duration of Study: Study was conducted at Armed Forces Institute of Cardiology & National
institute of heart diseases from Jan 2013 to Jan 2015
Patient and Methods: A total of 145 consecutive patients who underwent carotid artery stenting were
enrolled in study. All the symptomatic patients with carotid stenosis ≥50% or asymptomatic patients with
stenosis ≥60% determined by ultrasound or angiogram were intervened. Rail roading technique was used for
carotid stenting. Procedural success was defined as successful stenting with 20% or less residual stenosis.
Result: Out of 145 patients 128(88.27%) were male while 17(11.72%) were female with average age of 62.68
years. In all cases embolic protection devices were used. Pre-dilatation was done in 56(38.62%) cases while in
89(61.37%) direct stenting was done. Temporary pacemaker (TPM) transvenous lead was used in 134(92.41%)
patients. In 6(4.13%) patients procedure was abandoned. Only 3(2.06%) patients suffer stroke during
procedure while 4(2.75%) develops pericardial effusion due to TPM. Procedural success was achieved in
139(95.86%) patients.
Conclusion: Carotid artery stenting is an effective and safe modality for treatment of carotid artery stenosis.
