高血压是一种临床综合征。有明显原因可查的,称为症状性高血压或继发性高血压;目前尚查不到明显的病因者,称为原发性高血压或高血压病。症状性高血压中以肾脏病变所引起的为数较多,其中急、慢性肾炎,慢性肾盂肾炎等在临床表现上有一定的特点,诊断还比较容易。当肾动脉发生某种程度梗阻时,肾血流量减少,肾脏产生大量肾素,引起高血压。达种因肾血管病变所致之高血压,临床上称之为肾血管性高血压,也有人称之为肾动脉梗阻性高血压,或肾动脉狭窄性高血压等等。这种高血压极似原发性高血压,一般尿常规及肾功能检查都可能在正常范围以内,因此稍一不慎即被误诊为原发性高血压,甚至为恶性高血压。一般对高 Hypertension is a clinical syndrome. There are obvious reasons to check, known as the symptoms of hypertension or secondary hypertension; at present there is no obvious cause of the disease, known as essential hypertension or hypertension. Symptoms of hypertension caused by renal lesions in the number of more, including acute, chronic nephritis, chronic pyelonephritis and other clinical manifestations have certain characteristics, the diagnosis is still relatively easy. When a certain degree of obstruction occurs in the renal artery, renal blood flow decreased, the kidneys produce large amounts of renin, causing high blood pressure. Reached due to renal vascular disease caused by hypertension, clinically called renal vascular hypertension, also known as renal artery obstruction hypertension, or renal artery stenosis hypertension and so on. This high blood pressure is very much like essential hypertension, general urinalysis and renal function tests may be within the normal range, so a little mistake was misdiagnosed as essential hypertension, or even malignant hypertension. Generally high
