Ultrasound of abdominal blood vessels

Abdominal vascular ultrasound examination of abdominal aortic aneurysm, can measure the anteroposterior diameter, long diameter and wide diameter of the tumor, can be used as the preferred method for dissection of abdominal aortic aneurysm. Abdominal color Doppler ultrasound has important value in the diagnosis, differential diagnosis and treatment of inferior vena cava obstructive diseases. Basic Information Specialist classification: Digestive examination classification: ultrasound Applicable gender: whether men and women apply fasting: fasting Tips: Patients need to be prepared before the examination, should be fast, but no strict restrictions. When performing pelvic vascular examination, the patient needs to drink plenty of water and urinate to fill the bladder. Normal value Scope of application: 1, abdominal aortic aneurysm, dissecting aortic aneurysm, abdominal pseudoaneurysm, renal artery stenosis, mesenteric artery stenosis. 2, inferior vena cava obstruction syndrome (Budd-Chiari syndrome), inferior vena cava tumor, portal hypertension, portal vein embolization, portal vein cavernous degeneration, superior mesenteric vein embolization, renal vein thrombosis. 3. Vascular diseases of transplanted organs such as liver, kidney and pancreas. Clinical significance Abnormal results: 1. Ultrasound examination of abdominal aortic aneurysm can not only measure the anteroposterior diameter, long diameter and wide diameter of the tumor, but also detect the position, maximum thickness and actual lumen size of the wall thrombus, providing many aspects for clinical practice. Information, this is beyond the abdominal aortic angiography. Ultrasound imaging can clearly identify abdominal aortic aneurysms and para-aortic masses. Among many imaging examination methods, ultrasound examination is accurate, reliable, and simple, and has a preferred value. 2, ultrasonography can be used as the preferred method for dissection of abdominal aortic aneurysm, especially suitable for patients in the acute phase (within 2 weeks) whose condition has not been stabilized and no urgent surgery is needed. 3, color Doppler ultrasound (CDI) Although the diagnosis of renal artery stenosis, there are certain technical difficulties, the sensitivity of the instrument is also very high, but for patients with hypertension especially suspected renal vascular hypertension, Still an effective non-invasive screening tool. The diagnosis of this disease still depends on renal angiography. 4. CDI is less sensitive to the diagnosis of diffuse kidney disease. 5, CDI has important value in the diagnosis, differential diagnosis and judgment of the treatment of inferior vena cava obstructive diseases. Need to check the crowd: 1. Suspected patients with abdominal aortic aneurysm. 2, suspected renal vascular hypertension, need to diagnose patients. Precautions Preparation before inspection: 1. For patients with obesity, excessive gas in the intestinal lumen and scarring of the abdominal wall, abdominal vascular examination has certain difficulties. It is reported that about 10% to 50% of obese patients in foreign countries have difficulty in clearly displaying the superior mesenteric artery, celiac artery and renal artery. There is a certain degree of improvement in probe pressurization during scanning. 2, the patient needs to be prepared before the examination, should be fasting, but no strict restrictions. When performing pelvic vascular examination, the patient needs to drink plenty of water and urinate to fill the bladder. Requirements for inspection: Patients should eliminate tension and cooperate with doctors to avoid affecting the results. Inspection process The patient lies on the bed and uses an ultrasound instrument for imaging detection as directed by the doctor. Not suitable for the crowd Generally there is no suitable for the crowd. Adverse reactions and risks Generally no adverse reactions.
