Renal Doppler – Hospital Based Study and Review of Literature
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 8
Abstract
Introduction: Study was done for screening of Renovascular hypertension by Colour Doppler ultrasonograph. Renal Doppler is a noninvasive, inexpensive diagnostic procedure that is capable of accurately screening for renovascular disease. Study objective was to screen the patients suspected of renovascular hypertension by colour Doppler ultrasonography and to exclude patients for further evaluation by arteriography. Material and methods: Study was done for screening of renovascular hypertension by colour Doppler ultrasonography (CDUS). Patient was examined after 6hrs of fasting and was comfortably positioned supine, with head and shoulders slightly elevated.With the use of a 60 degree Doppler angle, a peak systolic velocity (PSV) was obtained within the aorta at the level of the superior mesenteric artery. The probe was directed slightly inferior to this position, and the origin of the right and left renal arteries were identified. The smallest sample volume was chosen. The sample gate was placed in center of arterial lumen. Side-to-side difference of the resistive index (delta RI) between the right and left kidney, indicating a RAS on the side with the relatively lower RI was calculated. Student’s t-test was used for determining significance of difference of means of RI and delta RI in normal and RAS. Results: In our study atherosclerotic RAS outnumbered Takayausu’s and FMD cases in our study. No accessory renal arteries were detected. In the present study, 25 of cases out of 50 had kidney size <8 cm or difference in size of two kidneys >1.5 cm out of which 11 were having RAS.Stenosis of the renal arteries were predominantly unilateral.The maximum and minimum value of PSV of renal artery at the site of stenosis in RAS patients were 255.4 cm/sec and 168 cm/sec respectively with a mean value of 226.59 cm/sec. Significant differences were noted for both the acceleration and acceleration time between the normal and stenosed renal artery groups.RI values of normal intrarenal vessels of 77 kidneys was high, resistive index of intrarenal vessels was low. Conclusion: This non-invasive, low cost and safe method can become primary modality in examination of RAS and may prevent unnecessary angiography.
