Visceral and renal protection in thoracoabdominal aortic surgery.

Ischemic renal failure and visceral ischemia are two serious complications of the surgery for thoracoabdominal aortic aneurysm. The introduction of left atrial bypass, partial bypass, total circulatory arrest, and selective visceral perfusion has reduced the incidence of these complications over the past two decades. Yet these complications still persist, suggesting the sub-optimal nature of the available strategies.

Deep vein thrombosis and euvolemic hyponatremia in a hypothyroid patient.

Hypothyroidism is a procoagulant state; hypothyroid females have greater risk of DVT than hypothyroid males. We present a case of primary hypothyroidism who presented with euvolemic hyponatremia and DVT that required thyroxine replacement and correction of hyponatremia. This highlights that hypothyroidism can present as euvolemic hyponatremia and deep vein thrombosis.

Mild functional ischemic mitral regurgitation following acute coronary syndrome: a retrospective study.

Background: Ischemic mitral regurgitation is a frequent complication of acute coronary syndrome. It primarily occurs in patients with a prior myocardial infarction but also may be seen with acute ischemia, a setting in which the MR typically resolves after the ischemia resolves. The vast majority of patients have "functional" ischemic MR.
