Remote ischemic preconditioning does not prevent acute mountain sickness after rapid ascent to 3,450 m.

Unlabelled: Remote ischemic preconditioning (RIPC) has been shown to protect remote organs, such as the brain and the lung, from damage induced by subsequent hypoxia or ischemia. Acute mountain sickness (AMS) is a syndrome of nonspecific neurologic symptoms and in high-altitude pulmonary edema excessive hypoxic pulmonary vasoconstriction (HPV) plays a pivotal role. We hypothesized that RIPC protects the brain from AMS and attenuates the magnitude of HPV after rapid ascent to 3,450 m.

Concomitant femoro-femoral bypass graft during surgery for acute type A dissection to treat lower limb malperfusion.

We report the case of a 69-year-old male patient who was admitted to our department with an acute type A dissection complicated by ischemia of the left lower limb. During surgery for acute type A dissection, the patient underwent concomitant femoro-femoral crossover bypass graft placement to ensure blood supply of the left lower limb during surgery and minimize ischemia-reperfusion injury. The patient underwent supracoronary replacement of the ascending aorta while in deep circulatory arrest with a deepest core temperature of 25°C.

Establishment of Extracorporeal Circulation under Local Anesthesia in a Patient with an Acute Type A Aortic Dissection Complicated by Cardiac Tamponade.

We report the case of an 82-year-old female who presented in a hemodynamically unstable condition to the emergency department of our institution. Transthoracic echo showed a hemodynamically relevant pericardial effusion and the suspicion of an intimal flap in the ascending aorta. The subsequent computed tomography scan revealed a Type A dissection that was limited to the ascending aorta.
