Abstract
To date, few study has defined the exact role or utility of intravascular ultrasound (IVUS) in the diagnosis and treatment of renal artery fibromuscular dysplasia (FMD). We investigated whether using an IVUS would provide additional insights in the hypertensive patients with focal renal artery FMD. A prospective, observational study, including all patients with focal renal artery FMD admitted to the Ruijin hospital during 6 consecutive years (2015-2021). Based on IVUS imaging, focal FMD patients were classified as two subtypes: intima-media thickening (IMT) and negative remodeling (NR) of the whole vessel. A total of 36 consecutive patients (24 ± 7, 13-39 years) with focal renal artery FMD were enrolled. Angiographic unifocal type was present in 22 (61.1%) patients and tubular type was present in 14 (38.9%) patients. Among 22 patients with unifocal, IVUS showed that 18 (81.8%) had IMT and 4 (18.2%) had NR. 14 patients with tubular, IVUS showed 3 (21.4%) had IMT and 11 (78.6%) had NR. No difference in age of onset, gender, BMI, initial BP levels were found between IMT and NR subtypes. However, hypertension cure rates of short-term (48 h after angioplasty) (76.2% vs. 26.7%, p = 0.004) and long-term (1-6years) (90.5% vs. 20.0%, p < 0.001) were higher in patients with IMT than in those with NR subtype. In present study, we described a new classification of focal renal artery FMD into IMT or NR subtype based on IVUS. Renal FMD Patients with IMT subtype were more likely to achieve cure of hypertension. We investigated whether using an IVUS would provide additional insights in the hypertensive patients with focal renal artery FMD. A new classification of focal renal artery FMD into IMT or NR subtype based on IVUS was described. Renal FMD Patients with IMT subtype were more likely to achieve cure of hypertension.

Renovascular hypertension in pediatric patients: update on diagnosis and management. Pediatr Nephrol 2021; 36:3853-3868. [PMID: 33851262 DOI: 10.1007/s00467-021-05063-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Revised: 03/11/2021] [Accepted: 03/19/2021] [Indexed: 01/03/2023]
Abstract
Renovascular hypertension (RVH) is defined as an elevated blood pressure caused by kidney hypoperfusion, generally as a result of anatomic stenosis of the renal artery with consequent activation of the Renin Angiotensin-Aldosterone System. The main causes include genetic and inflammatory disorders, extrinsic compression, and idiopathic alterations. RVH is often asymptomatic and should be suspected in any child with refractory hypertension, especially if other suggestive findings are present, including those with severe hypertension, abdominal bruit, and abrupt fall of glomerular filtration rate after administration of angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers. There is a consensus that digital subtraction angiography is the gold standard method for the diagnosis of RVH. Nevertheless, the role of non-invasive imaging studies such as Doppler ultrasound, magnetic resonance angiography, or computed tomographic angiography remains controversial, especially due to limited pediatric evidence. The therapeutic approach should be individualized, and management options include non-surgical pharmacological therapy and revascularization with percutaneous transluminal renal angioplasty (PTRA) or surgery. The prognosis is related to the procedure performed, and PTRA has a higher restenosis rate compared to surgery, although a decreased risk of complications. This review summarizes the causes, physiopathology, diagnosis, treatment, and prognosis of RVH in pediatric patients. Further studies are required to define the best approach for RVH in children.
