RESUMO
The ketogenic diet is frequently used as part of the treatment regimen for pediatric patients with refractory epilepsy. This diet is generally well tolerated, with constipation being the most described side effect. This case highlights a previously undocumented severe complication of a "keto-bezoar" formation related to the initiation of the ketogenic diet in a young infant.
RESUMO
Acute limb ischemia is a rare but potentially devastating event in a critically ill patient. In the pediatric population, limb ischemia is usually related to iatrogenic vascular damage and arterial thrombus formation secondary to arterial catheter placement. Children who have undergone femoral artery cannulation for venoarterial extracorporeal membrane oxygenation (VA-ECMO) are particularly at risk for this complication. In these cases, there have been reports of the successful use of a percutaneous limb reperfusion cannula to prevent or treat limb ischemia. We present a case of an 18 month old female who required VA-ECMO via carotid artery cannulation for viral myocarditis and subsequently developed acute lower limb ischemia related to a thrombus from an indwelling femoral arterial catheter in place for hemodynamic monitoring. This case highlights the usage of a distal reperfusion cannula and extracorporeal membrane oxygenation (ECMO) circuit for a novel purpose, which coupled with near infrared spectroscopy (NIRS) monitoring successfully re-established blood flow to the ischemic limb.
