Clinical significance of microcirculation examination in stroke patients

Microcirculation examination in stroke patients:

In recent years, research results have shown that it is of great clinical significance to apply microcirculation examination to stroke patients. To understand this problem, we must first know what is microcirculation examination.

Microcirculation refers to the blood circulation in the microvascular structure between human arterioles and venules, which is the most distal part of the circulatory system. Microcirculation examination can observe the fluid circulation dynamics of cell tissue material, energy and information exchange. There are about 10 parts of microcirculation that can be observed in the human body. For clinical convenience, the microcirculation of the nail bed of the fingers (toes) and the conjunctiva of the eyes of patients is often selected for examination as a microcosm of observing the microcirculation of the whole body.

Microcirculation examination has important clinical significance. Firstly, it can be used as an observation index of pathogenic factors affecting the body, which is helpful to clarify the pathogenesis of the disease; Secondly, microcirculation examination can be used as a reference index for the diagnosis of disease, and can cooperate with other examinations to judge the severity of disease. In addition, it can also be used as an objective index to observe the therapeutic effect, analyze the therapeutic mechanism of drugs, and provide a scientific basis for the clinical application value of the new method.

Because stroke is an acute and chronic cerebrovascular change, the microcirculation system is easy to change in the process of onset. Some people observed the nail fold microcirculation of stroke patients and found that about 40% of patients had tortuous and neoplastic canalicular loops. The tube loops of half of the patients were indistinct and irregularly arranged, and the tube loops were thicker and shorter than those of normal people.

The micro blood volume caliber of the affected limb of hemiplegia patients after stroke is thicker than that of the healthy side, the blood color is darker, the blood flow speed becomes slower, and there may be bleeding and bleeding. It was observed that the microcirculation of stroke patients was reduced in the number of loops. The tension of the pipe wall is poor. After active treatment, the condition improved, and the above changes also improved.
