A Catastrophic Complication of Thoracic Endovascular Aortic Repair: Aortoesophageal Fistula.

A 62-year-old man was admitted to the hospital due to sepsis secondary to a hemodialysis catheter-related infection that, upon diagnostic evaluation, demonstrated to be caused by P. aeruginosa and was treated with meropenem. Eradication of the infectious episode was confirmed by blood workup, including cultures. One month after the initial episode, the patient was readmitted due to a symptomatic penetrating aortic ulcer, which was classified as a cardiovascular emergency. The patient underwent an aortic stent-graft placement. Four weeks later, he presented to the emergency department with a 2-hour onset of thoracic pain and massive hematemesis. The esophagus and aortic segment with aortic stent graft were resected en bloc after an aortoesophageal fistula was diagnosed.

Hypertensive Emergency in a Woman with Systemic Sclerosis.

Systemic sclerosis (SSc) is a rare autoimmune disease that causes fibrosis in the skin and subcutaneous tissue, involving other organs such as the heart, lungs, kidneys, and gastrointestinal tract. Additionally, it can cause pulmonary arterial hypertension. Scleroderma renal crisis (SRC) is one of the most dreadful complications of SSc. SRC is a medical emergency that can present as a clinical picture of hypertensive encephalopathy. The pathophysiology involves an abrupt onset of moderate to severe hypertension that ranges from days to weeks; it is associated with an increase in plasma renin activity and acute kidney injury. It is known that by introducing angiotensin-converting enzyme inhibitors, the mortality decreases significantly in SRC. The renal biopsy plays an important role on the diagnosis and opportune treatment. We present a clinical case of SRC with a typical presentation of hypertensive emergency and acute kidney injury.
