CARDIOVASCULAR JOURNAL OF AFRICA • SMC-PAFCIC Abstracts October 2022 29 AFRICA was free of pain and no angiographical complications was seen. Few moments later, the patient was readmitted in the cathlab for chest pain and blood pressure decrease. Echocardiography revealed moderate pericardial effusion causing tamponade requiring immediate pericardiocentesis. Repeated angiography showed distal type III perforation of the OM treated by embolization of two detachable Concerto coils (Figure 3-4). Conclusion: Coronary artery perforation is a serious life-threatening complication of coronary percutaneous interventions. The location of CAP has an important implication for its specific management. Submission ID: 1483 CORONARY ARTERY STENT TOTAL DISLODGEMENT IN BRACHIAL ARTERY BOUTALEB AMINE MAMOUN, AWADA AHMAD MOROCCO, BELGIUM Introduction: The confirmation of coronary artery disease (CAD) is based on coronary angiography which evaluates the extent of coronary artery lesions. Percutaneous coronary interventions (PCI) have increased during the last years thanks to the improvement in coronary artery treatment techniques and materials. These interventions may present various complications. Stent loss is infrequent and may lead in some cases to serious embolism complications. Multiples retrieval techniques have been developed for this purpose but are time-consuming and require experience. Clinical Case: We report the case of a 59 years old patient presenting ischemic cardiomyopathy with prior stenting of the circumflex artery (LCx) in the context of acute myocardial infarction (AMI), and the mid-right coronary artery (RCA) with two drug-eluting stents (DES) in 2017. 1 year later the patient came back for very late stent thrombosis requiring new stenting. His past medical history includes weaned tobacco, high blood pressure, and dyslipidemia. He developed in August 2022 similar chest pain symptoms with significant ST segment depression in anterolateral leads at exercise ECG. The coronary angiography realized through the distal radial 6Fr approach revealed a smooth left coronary artery system with good angiographic results of LCx stenting. The Mid RCA stents were patent while subocclusive stenosis was found in the third stent. New PCI of the diseased segment was intended with JR 3.5 6 Fr guiding and Whisper MS advanced through distal RCA. While advancing a XIENCE Alpine 3,5x18mm through the previous stents, an abnormal resistance was noted by the physician which attempted to retrieve it causing partial stent dislodgement in the left main coronary artery. While removal of all the guiding and the stent as a unit toward the sheath the procedure was complicated by stent dislodgement at the right radial artery. Two Whisper wires were advanced through the radial artery and after failed attempts of tracking the stent with a balloon inflated downstream we could catch the stent in the brachial artery thanks to an En Snare through 6 Fr cubital access. In the meantime, stenting of distal RCA was real realized. Conclusion: Stent dislodgement is a dangerous complication of PCI and physicians should be aware of the different techniques available to prevent and treat it. In case of retrieval failure after multiple attempts, bail-out crush technique against the vessel wall is an option.
