AI-generated Abstract
This research investigates the outcomes of surgical intervention for patients diagnosed with hypertension stemming from renal artery stenosis. A study of 27 patients treated up to May 1966, following a thorough screening process, highlights a significant correlation between the surgical correction of renovascular hypertension and improved blood pressure levels. The findings indicate that while many patients experienced successful correction of hypertension post-surgery, a subset showed no notable change in blood pressure, underlining the complexity of renal artery stenosis management.

Background: Renal artery stenosis is the leading cause of secondary hypertension. Global prevalence of hypertension is 22% and across the WHO regions it is highest in Africa (30%). Up to 5% (3.5 to 4 million) of all occurrences of hypertension in the United States are caused by renal artery stenosis. The prevalence varies according to the population examined. This prevalence in our region is unknown and the diagnosis is probably missed in many patients. Timely diagnosis is important since renal artery stenosis is a correctable cause of hypertension. Objectives: To describe sonographic findings and determine the prevalence of renal artery stenosis in adult hypertensive patients suspected to have renal artery stenosis at Moi Teaching and Referral Hospital. Methods: This was a cross sectional study done at the ultrasound room in the Department of Radiology and Imaging, Moi Teaching and Referral Hospital, Eldoret between October 2015 and October 2016. Consecutive sampling technique was used on consenting adult hypertensive patients with clinical features suggestive of renal artery stenosis as per the American Heart association Guidelines of 2005 who underwent renal Duplex Doppler ultrasonography. A 3.5- 7 MHz curvilinear phase array transducer of a Philips HD11 XE machine model 2006 was used. All the images were reviewed by two consultant radiologists. Descriptive statistics were summarized for patient socio-demographics. Frequency tables were generated for categorical variables. Inferential statistics were done using Chi-square and Fishers exact tests. Results were presented using tables and charts. Results: The study included 169 participants with a median age of 46 (IQR 30). One hundred and five (62.1%) of them were females. In the findings; Sonographic prevalence of renal artery stenosis was 33.7%. Areas of aliasing was present in 62.5% of those with renal artery stenosis, post stenotic turbulence in 75.4% and thickening and calcification of arterial wall in 3.6%. Tardus- Parvus waveform pattern was seen in 66.1% (on the right) and 64.9% (on the left) in patients with renal artery stenosis. Echogenic kidneys were seen in 25 (43.9%) and loss of cortico medullary differentiation in 15 (26.3%) of the patients with renal artery stenosis. More females (63.2%) had renal artery stenosis than males, and majority, (43.8%) of those with renal artery stenosis were above 55 years. Conclusion: The sonographic prevalence of renal artery stenosis in adult hypertensive patients with specific clinical clues at MTRH was 33.7%. Parvus- Tardus was the commonest waveform pattern seen.

Abstrak Hipertensi sekunder jarang terjadi, namun harus menjadi kecurigaan pada pasien usia muda. Hipertensi sekunder harus didiagnosis dan ditatalaksana secara tepat. Stenosis arteri renalis merupakan salah satu penyebab hipertensi sekunder. Tujuan dari laporan kasus ini adalah menjelaskan diagnosis, patofisiologi dan tata laksana hipertensi sekunder akibat stenosis arteri renalis pada usia muda. Seorang pria berusia 17 tahun dengan gejala sesak nafas didiagnosis menderita hipertensi tahap 3 pada pemeriksaan rutin di Rumah Sakit Pasar Rebo, Jakarta. CT scan abdomen menunjukkan stenosis arteri renalis bilateral. Prosedur invasif PTA (Percutaneous Transluminal Angiography) arteri renalis kiri dilakukan di Pusat Jantung Nasional Harapan Kita dan satu stent dipasang dengan hasil baik. Tekanan darah setelah pemasangan stent normal.
