One calf is thick and the other is thin, what's the matter

There are many reasons why one leg is thicker than the other. It may be caused by disease or uneven force during daily exercise or walking. You should go to the hospital for examination in time, especially if it is caused by disease. You should be vigilant. If this situation has not occurred before and it has only appeared recently, it may be due to blood clots and thrombolytic therapy should be carried out in time.

Ascending venography

The location and range of thrombus can be understood. The patient lies supine in a semi-erect position with the head 30-45° high. First, tie a rubber tourniquet at the ankle to compress the superficial vein. Use a No. 12 puncture needle to directly percutaneously puncture the superficial vein on the dorsal pedis. Inject 80-100ml of 40% diatrizoate within one minute. Under the guidance of the TV screen, first take an X-ray of the calf, then take an X-ray of the thigh and pelvis. After the contrast agent is injected, quickly inject normal saline to flush the venous lumen to reduce the stimulation of the contrast agent and prevent the occurrence of superficial phlebitis.

It often shows a spherical or winding filling defect in the vein or the main vein is not visible. The distal vein is dilated and there are abundant collateral veins nearby, which all indicate the formation of thrombosis in the vein. The venous pressure is measured by continuous needle puncture of the superficial veins of the foot or ankle or the superficial veins of the arm with a glass measuring device filled with normal saline. The venous pressure is measured. The value needs to be compared with the venous pressure on the healthy side. This examination is only of diagnostic value when used in the early stage of the disease before the collateral vessels are established.

Non-invasive vascular examination

There has been great progress in the diagnosis of deep vein thrombosis. Non-invasive vascular examination methods have been used, including radioactive fibrinogen test, ultrasound examination, electrical impedance plethysmography, etc. Radioactive fibrinogen test is more sensitive to the examination of deep vein thrombosis in the lower leg. Ultrasound examination is the most valuable for the examination of iliofemoral vein thrombosis. If the above two examination methods are used, the diagnosis is still difficult to make clear and venography is still required. So far, there is no non-invasive examination method that can completely replace traditional venography. Continuous exploration and improvement of non-invasive examination methods is the direction of future efforts.
