The authors studied the seasonal cyclicity of the thrombotic and embolic process in the veins of the upper and lower extremities, as well as acute ascending varicothrombophlebitis in the great and small saphenous veins over eleven years. The study included a total of 1,513 patients. Of these, 593 (39.1%) presented with arterial ischaemia and 920 (66.9%) patients had ascending thrombophlebitis. The obtained findings showed the seasonal cyclicity of the thrombotic and embolic processes in the peripheral arteries and superficial veins. The maximal number of arterial thrombi was revealed in winter and that of embolisms and ascending varicothrombophlebitis in the spring period. No seasonal dependence for severe grade arterial ischaemia (category III according to the TASC II classification) was revealed.

KEY WORDS: seasonal fluctuation, arterial thrombosis, arterial embolism, thrombophlebitis.
