Abstract
This case report demonstrates embolization of echogenic material detected by transoesophageal echocardiography during a cemented total hip arthroplasty in a 76- yr- old woman without patent foramen ovale. During the placement of the acetabular and femoral components, and during relocation of the hip joint, a âsnow flurryâ appearing in the right atrium was followed by several highly echogenic and mobile emboli of various sizes, some of them with a vermiform shape 1 to 5 cm long. At skin closure, echogenic material was seen in the right branch of the pulmonary artery adherent to the vascular wall of the bifurcation of the main pulmonary artery. No changes were observed in any haemodynamic variable monitored (heart rate, systemic and right atrial pressures). Also, no desaturation was detected by pulse oximetry and blood gases at the time of embolism and there was no decrease in PetCO2. This case report is in line with other studies which failed to show a haemodynamic impact of TEE detected emboli during THA. Ce cas clinique dĂ©montre lâembolisation de matĂ©riel Ă©chogĂšne dĂ©tectĂ© par Ă©chocardiographie transoesophagienne (ETO) Ă lâoccasion de la mise en place dâune prothĂšse totale de hanche (PTH) cimentĂ©e chez une patiente de 76 ans sans foramen ovale permĂ©able. Durant la mise en place des composants acĂ©tabulaire et fĂ©moral, ainsi quâĂ la rĂ©duction de la hanche, est apparue une image de « tempĂȘte de neige » dans lâoreillette droite suivie dâemboles vermiformes de taille variable pouvant atteindre 1 Ă 5 cm de long. Durant la fermeture, du materiel embolique a Ă©tĂ© mis en Ă©vidence au niveau de la bifurcation de lâartĂšre pulmonaire, adhĂ©rant Ă la paroi vasculaire. Aucune rĂ©percus-sion hĂ©modynamique (rythme cardiaque, pressions artĂ©rielle et veineuse centrale) a nâa Ă©tĂ© observĂ©e. De mĂȘme, aucune dĂ©saturation dĂ©tectĂ©e par oxymĂ©rie de pouls et gazomĂ©trie artĂ©rielle nâa Ă©tĂ© constatĂ©e. La PetCO2 est restĂ©e stable. Ce cas clinique, en accord avec dâautres Ă©tudes, souligne que lâimpact hĂ©modynamique des emboles dĂ©tectĂ©s par ETO au cours de PTH cimentĂ©es est faible.Keywords
