ABSTRACT
A 63-year-old man with active COVID-19 infection and a history of coronary artery bypass grafting presented with acute thrombotic occlusion of saphenous venous graft which was anastomosed to the left anterior descending artery. Initial antegrade approach, complicated by a small leakage in the distal left anterior descending artery, was later converted to a retrograde approach via occluded saphenous vein graft. After successful stenting, TIMI 3 flow was achieved.
ABSTRACT
Objective Multisystemic inflammatory syndrome in children (MIS-C) is characterized by persistent fever, systemic hyperinflammation, and multiple-organ dysfunction. There are a few reports about MIS-C presenting with acute abdomen. The aim of this study is to demonstrate the clinical characteristics and treatment options for MIS-C-related acute abdomen and appendicitis. Methods This was a retrospective study conducted between April 2020 and October 2020 in our pediatric intensive care unit in Turkey. Patients between the ages of 1 month and 18 years who presented with acute abdomen and were ultimately diagnosed with MIS-C were included. Results Seven patients with a median age of 12.5 (interquartile range 10.5-13) years were enrolled. Four were females. The most frequent symptoms were fever, abdominal pain, and vomiting. Three patients had involvement of the appendix that required surgical intervention. All pathology reports were compatible with appendicitis. The other patients also had an acute abdomen. One patient had malignant hyperthermia during induction of anesthesia, so surgery was postponed and medical management was commenced. The clinical picture regressed with immunomodulation. All patients were treated with intravenous immunoglobulin and steroids. Four patients with acute abdomens improved with immunomodulation, and surgery was not needed. Conclusion MIS-C may present with an acute abdomen. Immunomodulation should be considered instead of surgery if the clinical course is not complicated.
