Incidences of injuries to peripheral veins indicated certain proportions among vascular injuries, most of venous injuries were accompanied by arterial injuries. Elevated venous pressure is an important factor which cause a compression syndrome in muscular compartment of the extremities when the injured major veins are ligated or not repaired. Persistent red deep color bleeding at wound site, diffusive subcutaneous hematoma, edema and cyanosis of the extremities are characteristics of the venous injuries. The examinations of Dopplor ultrasound and phlebography would be available for diagnosis of the venous injuries. The repair means include lateral sutere, vein pathch grafts, end-to-end anastomosis and autogenous venous grafts. The venous thrombosis may occur at the early phase after repair operations and also could be prevented.
ObjectiveTo explore the value of portable ultrasound in assessing peripheral vein thrombosis of the injured in Lushan earthquake on April 20, 2013. MethodsFrom April 20th to May 5th in 2013, 321 earthquake victims were admitted into our hospital, and 203 fractured patients of them accepted peripheral venous two-dimensional and color doppler ultrasound examination beside the bed every three days. ResultsSixty-three patients (82 locations) suffered from venous thrombosis in the 203 earthquake victims, and the rate was 31.03% (63/203). Among them, one suffered from iliac vein thrombosis; 53 patients (71 limbs) were attacked by lower limb venous thrombosis; 9 patients (10 limbs) suffered from upper limb venous thrombosis. The time was from 2 to 15 days after trauma when the victims were diagnosed to have thrombus at the first time, averaging (6.1±3.8) days. On admission day, 45 victims were diagnosed with peripheral vein thrombosis. Among them, 19 patients increased the scope of thrombus after admission in hospital, while 26 victims reduced the scope. Eighteen victims suffered from newly developed peripheral venous thrombus after admission in hospital. None of the hospitalized patients died of pulmonary embolism. ConclusionsThe victims injured in the earthquake have a high incidence of peripheral vein thrombosis, and the calf is the main site of the disease. After trauma, peripheral venous thrombosis occurs within a short time. Bedside portable ultrasound is the first choice for peripheral vein thrombosis in the earthquake victims.
