[The value of roentgen examination in reno-vascular hypertension (author's transl)]
Insights
Renal arteriography is a reliable diagnostic tool for renal artery stenosis, often used directly based on clinical symptoms. It accurately identifies stenosis, its cause, and significance, aiding in patient evaluation and diagnosis of related conditions.
Area of Science:
- Nephrology
- Vascular Imaging
- Radiology
Background:
- Renal artery stenosis is a significant cause of secondary hypertension.
- Accurate diagnosis is crucial for effective management and preventing complications.
- Traditional diagnostic pathways often involve screening tests prior to definitive imaging.
Purpose of the Study:
- To highlight the definitive role of renal arteriography in diagnosing renal artery stenosis.
- To emphasize the increasing use of arteriography based on clinical indications due to its reliability and low risk.
- To outline the comprehensive information provided by arteriography, including stenosis characteristics and associated pathologies.
Main Methods:
- Direct performance of renal arteriography based on clinical indications.
- Evaluation of arteriographic findings to determine the presence, cause, and hemodynamic significance of stenosis.
- Consideration of renal vein renin determinations when hemodynamic significance is uncertain.
- Assessment for other renal pathologies that may cause hypertension.
Main Results:
- Renal arteriography definitively diagnoses renal artery stenosis.
- The procedure identifies the cause and hemodynamic significance of the stenosis.
- Arteriography is valuable for evaluating post-operative patients.
- The technique can reveal other renal parenchymal diseases contributing to hypertension.
Conclusions:
- Renal arteriography is a highly reliable and low-risk procedure for diagnosing renal artery stenosis.
- Its direct application based on clinical judgment is increasingly common.
- The procedure provides comprehensive diagnostic information beyond stenosis, aiding in the management of renovascular hypertension and other renal diseases.
Abstract:
Renal arteriography plays a definitive role in diagnosis and evaluation of renal artery stenosis. Because of its high reliability and low risk, arteriography is more frequently being performed on the basis of clinical indications without reliance on screening tests. Arteriography will indicate the presence of stenosis, its cause, and the presence or absence of hemodynamic significance, and it is useful in evaluating the post-operative patient. Renal vein renin determinations are sometimes needed in evaluating the hemodynamic significance of the lesion. Arteriography may also reveal juxtaglomerular cell tumors, chronic renal inflammatory disease, or other diseases of renal parenchyma which could cause hypertension.
