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.
ObjectiveTo explore the value of ultrasound evaluation and marking before arteriovenous internal fistula in end-stage renal disease hemodialysis patients. MethodsTwenty-five uremia end-stage patients were admitted into our nephrology department from January 2012 to July 2012. All of the patients had encountered several times of fistula failure or had difficulty in establishing the forearm arteriovenous fistula. We focused on observing the brachial artery, radial artery, cephalic vein, the basilica vein and great saphenous vein. We measured the diameter of the vessels and marked the trend of arteries and veins in the body surface under the ultrasonic navigation. Our goal was to look for appropriate bypass vessels in the elbow and the upper arm. ResultsFourteen patients had endured several times of fistula failure. Among the 14 patients, 9 patients completed the surgery of reengineering fistula and autogenous great saphenous vein transplantation, 2 accepted artificial vascular transplantation, 1 completed the removal of blood clots in the left upper limb artificial blood vessels and arteriovenous internal fistula molding, and 2 gave up surgery. Eleven patients could not complete the arteriovenous fistula operation for the fine forearm superficial vein. Of them, 2 patients accepted artificial vascular operation, 6 underwent autogenous great saphenous vein transplantation, 1 with slender radial artery in diameter completed higher position fistula between the brachial artery and median cubital vein, and 2 gave up surgery. ConclusionArteriovenous internal fistula preoperative ultrasound assessment and marking have very important value in improving the success rate of operation in end-stage uremia patients.
