RESUMEN

Percutaneous transluminal angioplasty and stent placement for renovascular hypertension is a recognized albeit seldom used therapy. We present a case of severe renovascular hypertension, due to renal artery atherosclerosis, treated successfully with stent placement via the radial artery access approach.

RESUMEN

BACKGROUND: Infection with severe acute respiratory syndrome coronavirus disease 2019 (COVID-19) has been associated with both kidney and respiratory failure. During the early phase of the coronavirus disease pandemic, patients often required the use of mechanical assistance to provide adequate kidney and lung function. In this paper we describe the clinical outcomes of patients who required synchronous kidney and lung extracorporeal support for COVID-19. MATERIALS AND METHODS: All patients admitted to Baylor University Medical Center, Dallas, between February 1, 2020, to April 23, 2021, with COVID-19 who required both extracorporeal membrane oxygenation (ECMO) and continuous renal replacement therapy (CRRT) were retrospectively analyzed. Patients who were on hemo- or peritoneal dialysis prior to admission or who required veno-arterial (VA) ECMO were excluded. RESULTS: 35 patients with COVID-19 required ECMO and CRRT support. Four patients (11%) were excluded, 2 due to being on dialysis prior to admission and 2 due to the requirement of VA-ECMO. The median time on CRRT was 33 days (IQR 13 - 51). The median time on ECMO was 28 days (IQR 10.5 - 59.5). At 90 days, 9 patients had died (29%), 4 patients remained hospitalized, and 18 patients had been discharged: 10 to long-term acute care, 2 to inpatient rehabilitation, and 6 to home. CONCLUSION: Patients with severe COVID-19 requiring concurrent ECMO and CRRT in this institution had a 29% mortality at 90 days.

RESUMEN

Fibromuscular dysplasia is an uncommon cause of secondary hypertension. When the resulting hypertension cannot be successfully treated with medications, balloon angioplasty has been shown to be successful by disrupting the "webs" of tissue in the renal artery. We present a case of secondary hypertension due to fibromuscular dysplasia and the successful treatment with balloon angioplasty.
