Can deep vein ultrasound reveal hemangioma

With the continuous improvement of modern medical technology, many patients will rely on technical means to establish the diagnosis of most of the diseases, in medicine, auxiliary inspection has become more and more important, for patients with venous thrombosis is also so, today we will take a look at the lower extremity deep vein ultrasound inspection steps and some precautions, to help you understand this method of inspection.

1. Inspection steps: when checking the veins, ask the examinee to breathe calmly and relax the examined limb. First of all, the probe is placed on the surface of the body marking ready to check the blood vessels, the use of

two-dimensional ultrasound or color Doppler identification, clear display of the blood vessels of the cross-sectional image. Beginning in the groin, a transverse cut is made to determine the relationship between the common femoral vein and the femoral artery, followed by a longitudinal sweep

, which follows the course of the veins of the lower extremity from proximal to distal limbs to visualize the superficial femoral vein, the deep femoral vein, and the vena cava, respectively. The paired posterior tibial veins should be scanned from the mid-posterior aspect of the tibia

. The anterior tibial veins are easily visualized from the lateral aspect of the tibia. The peroneal veins can be swept from the mid-posterior aspect of the calf .

2. Precautions for ultrasound examination of the deep veins of the lower extremities: ( 1 )

Familiarize yourself with the veins of the lower extremities. I. Etiology of the formation of DVT of the lower extremities The three main elements of DVT are slow blood flow, damage to the wall of the vein, and hypercoagulability. The causes of DVT include genetic variations in enzymes,

associated factors and protein abnormalities, acquired factors such as trauma/fractures, post-surgical procedures, strokes, renal disease, venous cannulation, myocardial infarction, malignant tumors, cigarette smoking,

prolonged immobilization or bed rest, oral contraceptives, obesity, and advanced age.
