Konchalovsky

Rumpel-Leedow syndrome, named after the physician Michael Petrovich Konchalovsky, was recognized as a characteristic feature for the prognosis of renal failure in patients with proteinuria infected with immunosuppression. This syndrome is characterized by a significant increase in the permeability of the microvascular wall. According to some reports he

Konchalovsky's sign, also known as Rumpel-Leede's sign, is a clinical sign that manifests itself as the appearance of petechiae on the skin of the shoulder and forearm after brief compression of the shoulder with a tourniquet or rubber cuff of a sphygmomanometer. This symptom was named after Mikhail Petrovich Konchalovsky, a Soviet physician, and the German doctors Theodor Rumpel and Sigismund Leede, who contributed to its description.

Konchalovsky's symptom is an indicator of increased permeability or fragility of capillaries and precapillaries. It usually occurs in cases of prolonged septic endocarditis, which is a serious inflammatory disease of the inner lining of the heart caused by infection.

When performing a test for Konchalovsky's sign, the doctor places a tourniquet or rubber cuff of a sphygmomanometer on the patient's shoulder and compresses it for several minutes. At the same time, the pulse on the radial artery continues to be felt. After the tourniquet or cuff is removed, petechiae, which are tiny red or purple spots on the skin, may appear. This occurs due to the release of blood from damaged capillaries.

Konchalovsky's symptom indicates disturbances in the circulatory system and can be useful in diagnosing protracted infectious diseases, especially septic endocarditis. It indicates the presence of increased permeability of the vascular wall and may be one of the signs that help doctors confirm or exclude the diagnosis.

Although the Konchalovsky sign is relatively rare, it has diagnostic value and can be used in clinical practice to confirm certain conditions associated with disorders of vascular permeability. However, for accurate diagnosis and treatment, it is necessary to consult an experienced doctor who will take into account all other clinical data and symptoms of the patient.
