Venous embolism

Introduction

Introduction

Venous embolism is a venous blockage caused by excessive blood viscosity in the vein, which usually causes varicose veins. Varicose veins are common diseases of the venous system. The main reason for the formation is that they rarely change in the same posture for a long time. The blood accumulates in the lower limbs, and the venous pressure is broken under the condition of accumulating the venous valve for a long time, resulting in varicose veins. Varicose veins occur mostly in the lower extremities. The skin of the legs is red or blue, twisted blood vessels like spider webs, sputum, or hard nodules like tree tumors. The veins are abnormally enlarged and swelled.

Varicose veins occur mostly in the lower extremities. The skin of the legs is red or blue, twisted blood vessels like spider webs, sputum, or hard nodules like tree tumors. The veins are abnormally enlarged and swelled.

The varicose veins of the lower extremities have obvious morphological features, which can be confirmed by general physical examination. Intravenous ultrasound or contrast examination is required if necessary.

Diagnosis

Differential diagnosis

When the varicose veins are too severe, it is prone to recurrent ulcers, infections and bleeding. Misconceptions and wrong treatments may aggravate the symptoms of varicose veins.
