Abstract. Fibromuscular dysplasia is a non-inflammatory, non-atherosclerotic vascular disease, occurring predominantly in younger females. A histologically heterogeneous group of fibroplasia without an inflammatory component causes arterial narrowing. It affects mostly one or both renal arteries, cervicocranial or visceral arteries, leading to hypertension, renal failure/renal infarction or stroke/transient ischaemic attack. We present the case of a young female patient with abdominal aortic coarctation, history of acute renal failure, and critical hypertension due to pseudo-occlusion of both renal arteries. We performed renal artery revascularization specifically by using the Riolan anastomosis as feeding vessel.

Background. Renovascular hypertension (RVH) is an elevated blood pressure caused by partial or complete occlusion of one or both renal arteries or their branches. According to different studies, renal artery stenosis accounts for 5–10% of all cases of hypertension in children. The most common causes of renal artery stenosis are deemed to be atherosclerosis and fibromuscular dysplasia.Case description. The article describes clinical case of a newly diagnosed renovascular hypertension amid background of fibromuscular dysplasia of renal arteries in a 6-year old child, particulars of the clinical course, laboratory and instrumental methods of investigation and treatment including aortography and balloon angioplasty of renal arteries.Conclusion. This case report illustrates that in the absence of complaints and pronounced clinical symptoms the diagnosis of renovascular hypertension in a 6-year old child could not be established for a long time. Timely detection of elevated BP in children, including the young ones, not only during visiting specialist physicians but also during prophylactic examination by pediatrician, is required for early diagnosis of the disease and development of the examination and treatment strategy.

Clinical Cases

Objective: Renal vascular thrombosis is a thrombotic blockage of the major renal arteries resulting in acute damage or chronic kidney disease. The study aims to analyze rare clinical cases of renal artery thrombosis with following renal infarction. Materials and methods: The article present a retrospective study of examination and treatment results of patients diagnosed with the renal arteries thrombosis in the urological hospital of the Irkutsk Clinical Hospital No. 1 in the period 2012-2020. Results and Discussion: During the entire observation period, there were two clinical cases of acute renal artery thrombosis. The 86-year-old woman developed thrombosis because of atrial fibrillation, which was probably the result of inadequate correction (insufficient dose of anticoagulant). Kidney infarction had complications like rapid suppuration because of chronic urinary infection and calculus of the renal pelvis. It resulted in nephrectomy with subsequent recovery. The second case was the 45-year-old man examined according to existing standards, and the diagnosed-on time in the first hours of the disease. However, complete thrombosis of the right renal artery neutralized the effectiveness of conservative therapy with warfarin. In this case, nephrosclerosis and renal failure were natural. Conclusion: Renal artery thrombosis is a rare pathology that requires special attention from the clinician due to the high risk of renal function loss. Timely diagnosis and correct treatment tactics are especially important. Bangladesh Journal of Medical Science Vol.20(3) 2021 p.550-555

Abstract The etiology of renal artery stenosis (RAS) and abdominal aortic coarctation (AAC) causing the midaortic syndrome (MAS), often resulting in renovascular hypertension (RVH), remains ill-defined. Neurofibromatosis type 1 (NF-1) is frequently observed in children with RVH. Consecutive pediatric patients (N = 102) presenting with RVH secondary to RAS with and without concurrent AAC were prospectively enrolled in a clinical data base, and blood, saliva and operative tissue, when available, were collected. Among the 102 children, 13 were having a concurrent clinical diagnosis of NF-1 (12.5%). Whole exome sequencing was performed for germline variant detection, and RNA-Seq analysis of NF1, MAPK pathway genes and MCP1 levels were undertaken in five NF-1 stenotic renal arteries, as well as control renal and mesenteric arteries from children with no known vasculopathy or NF-1. In 11 unrelated children with sequencing data, 11 NF1 genetic variants were identified, of which 10 had not been reported in gnomAD. Histologic analysis of NF-1 RAS specimens consistently revealed intimal thickening, disruption of the internal elastic lamina and medial thinning. Analysis of transcript expression in arterial lesions documented an approximately 5-fold reduction in NF1 expression, confirming heterozygosity, MAPK pathway activation and increased MCP1 expression. In summary, NF-1-related RVH in children is rare but often severe and progressive and, as such, important to recognize. It is associated with histologic and molecular features consistent with an aggressive adverse vascular remodeling process. Further research is necessary to define the mechanisms underlying these findings.

Renal artery stenosis (RAS) is rare in young patients without fibromuscular dysplasia (FMD). RAS is primarily classified as having two major etiologies, namely, atherosclerosis and FMD, with 90% and 10%, respectively. We report a case of a female in her mid 20s who developed hypertension due to RAS with no evidence of FMD or underlying renal dysfunction and underwent successful angioplasty and stenting.

Common Causes

Introduction: The most common causes of renal artery disease are stenosis, as a consequence of atherosclerosis and fibromuscular dysplasia. Computed tomographic (CT) angiography is a non-invasive method, which enables visualization of vascular structures and walls of blood vessels, as well as morphology of the renal parenchyma. Objective: To determine the importance of CT angiography in detecting the cause and degree of renal arterial disease. Methods: A total of 45 patients were included in the cross-sectional study conducted from March 2017 to March 2019 in the KBC DR Dragiša Mišović-Dedinje, Belgrade, Serbia. Criteria for inclusion were suspicion of secondary arterial hypertension, patients in preparation for kidney transplantation and in the follow-up period after transplantation, as well as patients with suspected traumatic lesions. We analyzed the causes of the disease, the morphology of the blood vessel wall, the percentage of stenosis, and the renal parenchyma. Results: The most common causes of renal arterial disease are atherosclerosis, which was found in 33 (73%) patients, renal artery aneurysm was found in 5 (11%) subjects, fibromuscular dysplasia in 4 (8.9%) and trauma in 1 (2) , 3%) of the patient. There were 10 (22.2%) patients with a significant (average 80 ± 14.5%) degree of stenosis. The sensitivity of CT angiography in the detection of atherosclerotic changes in the renal arteries was 87.9%, while the sensitivity of CT angiography in the detection of fibromuscular dysplasia was 75%. A statistically significant correlation was found between atherosclerotic stenosis of the renal arteries and a positive CTA finding (p = 0.0002). Conclusion: CT angiography is an important method of visualization and quantification of pathological changes in the renal arteries.
