RESUMEN
BACKGROUND: Stent dislodgement is a life-threatening complication that can result in coronary artery embolization, stent thrombosis, acute myocardial infarction, and even death. Severely angulated, heavily calcified, and previously stented coronary arteries are associated risk factors. With the development of different lesion preparation techniques and the drug eluting stent era, the reported incidence of stent dislodgement has decreased to < 1% in the last few years. CASE PRESENTATION: We report a case of a 64-year-old Moroccan man complicated during percutaneous intervention in the left main artery by the loss of two stents. This complication was successfully managed by passing the stent's balloon into the stent and then fully expanding it. In our case, the device's characteristics were involved and could play a role in such complications, but it is still not well understood. CONCLUSIONS: The main treatment option is stent retrieval with different available techniques. If retrieval of the stent is impossible, crushing it against the blood vessel wall could be considered.

BACKGROUND: Hemorrhagic complications are quite common in the rare cases where thrombolysis is performed. Ischemic stroke in the aftermath of thrombolysis for a ST elevation myocardial infarction is a very rare and paradoxical complication. With these observations in mind we report two interesting cases of ischemic stroke which occurred after fibrinolytic therapy with tenecteplase for a ST elevation myocardial infarction. CASE PRESENTATION: The first case was a 56-year-old African man who presented with an acute infero-basal ST elevation myocardial infarction 6 hours after chest pain onset. Thrombolysis with tenecteplase was performed and few minutes later an ischemic stroke occurred. The second patient was a 65-year-old African man who presented with an acute infero-basal ST elevation myocardial infarction 5 hours after chest pain onset. Thrombolysis was performed and 10 hours later an ischemic stroke occurred. CONCLUSIONS: Hemorrhagic stroke is not the only complication of thrombolysis, ischemic stroke can occur even if it is an extremely rare complication. The two cases on which we report shed light on the association between fibrinolytic therapy and ischemic stroke, the pathophysiology of which is not well understood.
