What are the early symptoms of renal artery embolization and renal artery thrombosis? There must be a lot of clinical manifestations for this disease. In fact, in the face of renal artery embolization and renal artery thrombosis, we must know the specific hazards. Renal artery embolization and renal artery thrombosis is still very important, then how to show it?
The clinical manifestation of renal artery thrombosis or embolization depends on the speed, extent and extent of arterial occlusion. Small branch clogs may not have any symptoms or signs, and renal artery trunk and its large branch blockage often appear typical clinical manifestations.
1. The performance of acute renal infarction patients can suddenly appear severe low back pain, abdominal pain, back pain, can be similar to renal colic, to the thigh radiation, can also be similar to acute cholecystitis, pain to the shoulder radiation, some cases can be similar to Acute pancreatitis or acute myocardial infarction. Often fever, vomiting, nausea, physical examination of the affected side of the kidney percussion pain and tenderness significantly. Increased white blood cells, nuclear left shift. May have hematuria and proteinuria. Serum enzyme increased, aspartate aminotransferase often increased immediately after infarction, 2 weeks after the return to normal, alkaline phosphatase often 3 to 5 days after infarction rose to the peak, 4 weeks after the return to normal.
2. About 60% of hypertensive patients in the renal artery blockage, due to renal ischemia, renin release in the short term hypertensive. Generally last 2 to 3 weeks, of which about 50% of patients left persistent hypertension, while the other half of patients with normal blood pressure can be restored. Renal artery occlusion may occur in hypertensive crisis.
3. Acute renal failure slow onset of thrombosis can occur chronic renal insufficiency, acute occlusion of the renal artery branch blockage may be acute renal insufficiency, and renal artery or solitary renal renal artery embolization is acute rapid deterioration of the kidney Functional failure, often have to immediately hemodialysis, if not open as soon as possible occlusion of the artery, the prognosis is poor. In addition, the clinical manifestations of renal cholesterol emboli, often associated with other causes of renal embolism disease is different, rare renal infarction. The most common clinical manifestations are acute, subacute or chronic progressive renal insufficiency, and thus make the diagnosis of renal cholesterol embolism. Atherosclerotic embolization is feasible to the small arterial branch and affect the small arteries, resulting in decreased GFR. Due to the embolization of ischemic renal segment of the release of renin can cause unstable hypertension. Acute renal failure associated with atherogenic embolism is often associated with an increased urinary excretion fraction when there is a significant decrease in tubule injury. But renal insufficiency can also be non-oligurative and slow progress, which is due to spontaneous plaque ulcers and rupture of recurrent. Urine test can be found in moderate proteinuria, microscopic hematuria or pyuria. The latter does not have diagnostic significance.
Renal artery embolization and renal artery thrombosis early clinical symptoms described above a lot, in fact, the clinical manifestations of the disease is still very important, then the disease must pay attention to the job, and only a timely understanding of the clinical manifestations of the disease, To be able to in-depth understanding of the disease.
