Comparison of intima-media thickness of common and internal carotid arteries of patients with ischemic stroke and intracerebral hemorrhage

BACKGROUND

Role of atherosclerosis in the pathogenesis of ischemic and hemorrhagic infarctions is still matter of debate. Intima-media thickness (IMT) of the common carotid artery (CCA) and internal carotid artery (ICA) are markers of atherosclerosis. The aim of this study was to compare CCA IMT and ICA IMT of patients with ischemic and hemorrhagic infarction.

METHODS

Two equal groups of 80 patients with small and large vessel ischemic stroke and 80 patients with non-traumatic intracerebral hemorrhage (ICH) who referred to our central teaching hospital of Zahedan were assessed in this descriptive study. IMT of four arteries (right and left CCA and ICA) were measured, and collected data were analysis using Student's t-test.

RESULTS

There were 137 males (57.1%) and 103 (42.9%) female with mean age of 62.7 ± 11.7. Mean right CCA IMT of patients with small vessel diseases (SVD), large vessel diseases (LVD), and ICH were 0.564 ± 0.130, 0.623 ± 0.150, and 0.580 ± 0.140 mm, respectively (P = 0.032). Mean left CCA IMT of patients with SVD, LVD, and ICH were 0.569 ± 0.120, 0.618 ± 0.120, and 0.573 ± 0.130 mm, respectively (P = 0.039). The above findings for right ICA were 0.572 ± 0.120, 0.569 ± 0.140, and 0.522 ± 0.130 mm, respectively (P = 0.145). Those findings for left ICA IMT were 0.525 ± 0.110, 0.554 ± 0.120, and 0.527 ± 0.120 mm, respectively (P = 0.257).

CONCLUSION

Our findings showed that by using CCA IMT, differentiation between small and large vessel infarctions and hemorrhagic infarctions can be made.
