deep vein patency test

Deep vein patency test: The deep vein patency test is an auxiliary examination method for checking whether the venous blood vessels are normal. The deep venous patency test is a method for identifying signs of patency of the deep veins of the lower extremities. In particular, whether the varicose veins of the lower extremities can be an important sign of surgery. If the superficial varicose veins are more obvious after the activity, the tension is increased, and even the pain is painful, it means that the deep veins are not smooth. Through this examination, the corresponding symptoms can be judged. Basic Information Specialist Category: Cardiovascular Examination Category: Other Examinations Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: Test negative (-): indicating deep vein patency. Positive: Positive test (+): indicates that the deep vein is not smooth. Tips: The patient actively cooperates with the doctor, the doctor patiently operates and carefully observes the results. Normal value A negative test (-) indicates deep venous patency. Clinical significance A positive result test (+) indicates that the deep vein is not smooth. If the varicose veins of the diseased vein are significantly relieved after the activity, it indicates that the calf muscle pump contracts after the calf activity, forcing the venous blood stagnant in the great saphenous vein (superficial vein) to pass through the communication branch between the deep and shallow veins, and to the deep venous return. Due to the deep venous patency and good function, venous blood can be further returned to the iliac vein. If the varicose veins of the diseased veins are not alleviated after the activity, the weight will increase or the patient feels pain in the lower limbs, indicating that although the calf muscles contract after the calf movement, it is supposed to force the venous blood stagnated in the great saphenous vein (superficial vein). Through the traffic branch between the deep and the shallow veins, the deep veins are returned, but the deep veins of the lower limbs are not smooth, the function is poor, and the venous blood in the deep veins cannot be refluxed. At this time, the blood stasis of the saphenous vein (superficial vein) of the lower limb of the patient is aggravated, and the congestion of the deep vein is also aggravated. Therefore, the varicose veins of the lesions are not alleviated, but the patients often feel pain in the lower limbs. People with cardiovascular disease who need to be examined. Low results may be diseases: lower extremity varicose veins, varicose veins, simple lower extremity varicose veins may be high disease possible diseases: lower extremity arteriosclerosis obliterans, lower limb traffic venous valve closure insufficiency Taboo before check: Maintain normal diet and sleep. Requirements for examination: The patient actively cooperates with the doctor, the doctor patiently operates, and carefully observes the results. Inspection process The tourmaline was used to block the trunk of the superficial vein of the thigh, and the paralyzed patient kicked the leg vigorously or performed squatting activity for more than 10 times. At this time, the contraction of the calf muscle pump forced the venous blood to flow back to the deep vein, so that the varicose veins were evacuated. If the superficial varicose veins are more obvious after the activity, the tension is increased, and even the pain is painful, it means that the deep veins are not smooth. Not suitable for the crowd Inappropriate population: venous ligation or resection of the lower extremities.
