A & A case reports

Muscle-eye-brain disease is a rare autosomal recessive disorder characterized by congenital muscular dystrophy, ocular abnormalities, and brain malformation. We report an intraoperative hyperkalemic cardiac arrest following the administration of succinylcholine in a child with muscle-eye-brain disease. The disease was diagnosed only after this event. Our experience suggests that preoperative determinations of serum concentrations of lactate and creatine kinase may be useful if clinical signs consistent with myopathy are present.

Not all postpartum headaches are caused by dural puncture, and it is possible for postpartum patients to have >1 cause for headache. After neuraxial block with an incidental large-gauge dural puncture, our patient developed a severe, classic postdural puncture headache which initially responded to an epidural blood patch. ⋯ Computerized tomography and magnetic resonance imaging revealed an enlarged pituitary gland with a possible hemorrhagic focus; all endocrine parameters were normal. The patient was ultimately diagnosed with lymphocytic adenohypophysitis, an autoimmune inflammation of the anterior pituitary gland.

Percutaneous valve-in-valve therapy is a life-saving procedure for patients at high risk of reoperation due to dysfunctional bioprosthetic valves. We have reviewed 3 typical cases of a valve-in-valve procedure using high-quality images to demonstrate the suitability of this method for aortic, mitral, and tricuspid positions. Three-dimensional transesophageal echocardiography combined with other modalities such as computerized tomography and fluoroscopy are key elements for anesthesia and procedural guidance, especially as immediate tools to assess valvular function and specific procedure-related complications.
