He entered the literature with the method he applied to the constriction of the carotid artery.

Associate Professor Dr. Uzun, who works at Trabzon University Ahi Evren Thoracic and Cardiovascular Surgery Training and Research Hospital, developed the "Interposition Endarterectomy" technique for patients at risk of stroke due to stenosis of the carotid artery.

With this technique, the part of the vein that is affected by the disease is completely removed, and an artificial vein or the patient's own vein is placed in that area and the connection is made again.

Thus, the possibility of separation between the vascular layers is eliminated, and the risk of surgery-related stroke is greatly reduced.

The method Uzun applied to 20 patients in 2 years was also featured in the international journal Annals of Vascular Surgery.

Assoc. Prof. Dr. Kemal Uzun told an AA correspondent that he developed a different technique than the one used for years to treat carotid artery stenosis.

Uzun stated that 20 percent of patients experience stroke due to narrowing of the carotid artery, and that the disease should be treated once it is detected.

Uzun explained that doctors clear the narrowed plaque using two techniques available in the literature for surgical treatment, and shared the following information:

Although these surgeries are performed to prevent strokes, sometimes patients can experience a stroke related to the surgery. This is largely because while you might think of the veins as a single-layered organ, they are actually composed of layers. With current techniques, when removing the plaque that narrows the artery, these layers can be separated from each other. While plaque can sometimes be removed very well, sometimes the layers can separate from each other in the part of the artery that continues towards the brain. This is the biggest cause of a stroke related to the surgery.

Uzun pointed out that he developed the technique called "Interposition Endarterectomy" to reduce this risk and noted the following:

"We completely remove the damaged tissue. Therefore, we close the gap by inserting a piece of blood vessel. No diseased tissue remains. The separation of the layers of the blood vessel, the formation of a clot, and the risk of a stroke as a complication of the surgery, theoretically significantly reduce. We've also performed a procedure we're confident in. We've been performing it for two years, and our results are excellent."

Uzun explained that he wanted to share the technique with the scientific world once the results were good, saying, "We submitted our article to one of the world's most respected journals. Due to its academic merit, our first application was accepted and published in May 2025."

Zafer Yanak, 62, who came to Trabzon from Gümüşhane for treatment due to numbness and loss of strength in his left arm, said he underwent surgery using the new technique.

Yanak expressed his satisfaction with the treatment, saying, "I'm pain-free. I'm in perfect health."

Engin Demirhan stated that a narrowing of the carotid artery was detected in the hospital where he came due to blowing in his ear.

Demirhan stated that he underwent surgery with a new technique after the diagnosis and that he feels very well now.
