körbefolyásolás

Körbefolyásolás is a Hungarian medical term that describes the circumferential compression or occlusion of blood vessels, resulting in a reduction or cessation of blood flow to the affected tissue. The word is derived from the Hungarian roots kör– (meaning “around” or “circular”) and folyásolás (meaning “to flow”), literally indicating a situation in which vascular flow is obstructed in a round or encircling manner.

The condition can arise in several clinical contexts. In trauma, fractures or dislocations may produce a surrounding hematoma that compresses adjacent vessels, causing local ischemia. In elective surgery, the use of tourniquets or vascular clamps may induce temporary körbefolyásolás to limit blood loss; the subsequent release of the clamp can precipitate reperfusion injury. Neurological cases such as cranial nerve palsies sometimes involve a vessel that paradoxically compresses a nerve as well as surrounding vasculature, giving rise to a combined vascular‑neural impairment.

Clinically, the signs of körbefolyásolás include pallor, coolness, diminished pulses, numbness, and, if prolonged, tissue necrosis. Diagnostic tools comprise Doppler ultrasonography, magnetic resonance angiography or CT angiography to visualize the extent of vessel narrowing and the territory at risk. Treatment focuses on relieving the pressure through surgical decompression, removal of compressing mass, or intra‑arterial thrombolysis in cases of embolic occlusion. Post‑intervention monitoring avoids re‑occlusion and manages reperfusion-related complications.

The term remains primarily used in Hungarian-speaking medical literature and is analogous to the English phrase “circumferential vascular occlusion” in English anatomy and clinical texts.
