Characteristics, treatment, and outcomes of spontaneous renal artery dissection: a 10-year retrospective single-center experience.
Background: Spontaneous renal artery dissection (SRAD) is a rare cause of renal failure and renovascular hypertension, with the diagnosis often being delayed and treatment varying across different centers. The objective of this retrospective cohort study was to scrutinize the characteristics, treatment modalities, and outcomes of patients with SRAD at our center over the past ten years. Furthermore, the study sought to identify the most suitable treatment options for different categories of patients with SRAD.
Methods: Data from 21 consecutive patients who presented with symptoms of SRAD from December 2013 to December 2023 were collected. Lesion characteristics, treatment options, blood pressure (BP) control, serum creatinine and estimated glomerular filtration rate (eGFR) were analyzed. A paired t-test was used for comparisons of BP, serum creatinine, and eGFR. An independent samples t-test was used to analyze baseline BP and BP change in different treatment groups.
Results: The mean age, weight, and height of patients with SRAD was 49.2±13.0 (range, 18-69) years, 69.0±9.7 (range, 50-80) kg, and 1.7±0.1 (range 1.6-1.8) m, respectively. New-onset hypertension was found in 8 (38.1%) patients. Renal artery dissecting aneurysm and renal artery stenosis were found in 1 (4.8%) and 4 (19.0%) patients, respectively. Supportive medical treatment alone, endovascular intervention, and nephrectomy were required in 15, 4 and 2 cases, respectively. Stable renal function and satisfactory hypertension control were obtained in all treatment groups, with a median follow-up of 18.1 (range, 12-32) months.
Conclusions: Medical management is a reasonable choice in most patients with SRAD. Interventional management is an efficacious strategy for the management of renovascular hypertension and the preservation of renal function.
