Determination of hemodynamic and rheological properties in carotid artery diseasesAuthor(s): Halil Ibrahim Ozdemir*, Celal Cinar & Ismail Oran
Aim: The cause of all carotid artery diseases is directly related to the morphological structure and hemodynamic properties of the carotid artery and its branches. Our aim of research is to find answers to the following two questions. 1-Compared to normal patients, how can hemodynamic and rheological changes occur in the carotid arteries and its branches of the patients with stenotic, aneursymatic and dissection? 2-And how do these changes differ according to diseases?
Results: Patients with extra cranial and intra cranial aneurysms were found to have lower shear stresses, slower blood flow rates, but on the contrary, having higher blood pressure and higher Reynolds numbers that affect the artery walls. On the other hand, higher shear stresses, higher blood flow velocities, lower Reynolds numbers and lower wall tension values were found in patients with dissection.
Conclusion: It has been concluded that the presence of aneurysm and dissection may play an important role in vascular shaping, or vice versa.
