White Spot Symptom

White Spot Symptom: Indicator of Vascular Insufficiency

The White Spot symptom is a clinical feature characterized by the appearance of a long-lasting white spot on the skin of the dorsum of the foot or hand after finger pressure. This symptom is an indicator of vascular insufficiency in the distal extremities and may be associated with impaired sympathetic innervation.

Vascular insufficiency is a condition in which the blood supply to tissues is limited due to obstructions in the blood vessels. In the case of White Spot Symptom, this restriction of blood flow occurs in the distal extremities, such as the feet and hands. When pressure is applied to these areas of the skin with a finger, the normal redness caused by the temporary interruption of blood flow is not fully restored and a white patch appears instead.

The White Spot symptom can be associated with a variety of medical conditions and factors, including atherosclerosis, thrombosis, embolism, vasospasm, and diabetic neuropathy. This symptom can also be observed in reflex vascular disorders such as Raynaud's syndrome, in which the vessels periodically contract due to disturbances in sympathetic innervation.

It is important to note that the White Spot Symptom is just one of many clinical signs that indicate problems with the circulation or vascular system. To accurately diagnose and determine the cause of the symptom, a comprehensive medical examination is necessary. The doctor may use a variety of methods, including a clinical examination, blood tests, Doppler ultrasound, angiography and other instrumental tests.

Treatment for White Spot Symptom depends on its underlying cause. In some cases, correction of vascular insufficiency or treatment of the underlying disease causing the symptom may be necessary. Your doctor may prescribe medication, physical therapy, lifestyle changes, or surgery depending on your specific situation.

In conclusion, the White Spot Sign is an important clinical sign indicating possible circulatory and vascular problems in the distal extremities. Therefore, if such a symptom is detected, it is necessary to consult a doctor for further examination and determination of the cause. Accurate diagnosis and timely treatment can help prevent the progression of vascular diseases and improve the patient's overall condition.



What is a “white spot” symptom?

The term “white spot symptom” was introduced by Strumpelman and Mayer (Strumpe, Mayer) in 1918 as the name of a symptom that combines several clinical signs of insufficient blood supply to the extremities. Later, Laberge proposed a synonym for this symptom - “stage of whiteness.”

Description of the symptom. When rubbing an area of ​​skin (palm) of a patient over the ulnar and/or radial arteries, a state of redness first occurs. Then, after the pressure on the skin ceases, a dotted white part appears - a white spot, which gradually acquires color intensity and turns into the original red color. It takes 3 to 5 minutes for the redness to completely disappear. The degree of change in skin color may vary. Often the pallor of the surface of the skin is so significant that the skin becomes yellow, and only along the periphery of the spot and for some time there remain areas of pallor, almost comparable to the general color of healthy skin.
