Effect of Mechanical Thrombectomy on Thyroid Hormone Levels


Clinical trial finds that thyroid hormone levels decrease after mechanical thrombectomy for cerebral infarction

The thyroid gland is one of the most important endocrine organs of the body located in the neck. It produces T3 and T4 hormones that play an important role in the body's metabolism and energy production. Thyroid hormone levels are known to be affected by stress and illness.

Cerebral infarction, commonly known as a stroke, is a medical emergency that occurs when blood flow to a part of the brain is disrupted. Mechanical thrombectomy is a procedure that involves the removal of a blood clot from an artery in the brain, which is a common treatment for cerebral infarction.

Thyroid hormones control the body’s metabolism and several other functions. The researchers believe that there might be a decrease in thyroid hormone levels after mechanical thrombectomy due to the use of an iodine contrast agent and the stress of the procedure, and the subsequent inflammatory response in the body. However, further research is needed to confirm this hypothesis.

Clinical Trial

A clinical trial has found that thyroid hormone levels tend to decrease after mechanical thrombectomy for cerebral infarction. It analyzed 31 patients who underwent mechanical thrombectomy for cerebral infarction. The researchers measured the patient's thyroid hormone levels (T3, T4, and TSH) before and after the procedure.

The results of the clinical trial demonstrated that there was a significant decrease in the T3 and TSH levels 24 h after mechanical thrombectomy. Moreover, there was a correlation between the decrease in the T3 levels and the amount of iodine contrast agent used in MT.


The findings of this clinical trial have important implications for patients who undergo mechanical thrombectomy for cerebral infarction. A decrease in thyroid hormone levels can cause a range of symptoms, including fatigue, weakness, and difficulty concentrating. These symptoms can have a negative impact on a patient's recovery and quality of life.
Therefore, the researchers suggest that physicians should monitor the thyroid hormone levels of patients who undergo mechanical thrombectomy for cerebral infarction.


The clinical trial has shed light on the effect of mechanical thrombectomy on thyroid hormone levels. The findings suggest that patients who undergo this procedure may experience a decrease in thyroid hormone levels, which could impact their recovery and quality of life. Physicians should monitor thyroid hormone levels in these patients and take appropriate measures to manage any symptoms that may arise.
