Extracorporeal membrane oxygenation (ECMO) is becoming a gold standard in acute heart failure, not responsive to inotrops and intra-aortic balloon contrapulsation. This diffusion is due to the possibility to implant it through peripheral cannulation and to perform long-time assistance. Nevertheless, this technique implies some problems concerning inferior limb perfusion. It is widely accepted that arterial distal cannulation and perfusion of the limb is mandatory, especially for long periods of assistance; but the necessity to implant a distal venous drainage is still discussed. We would like to present our experience on peripheral ECMO where we could avoid venous distal drainage uneventfully.
In rare cases of posterior myocardial infarction, septal rupture is the consequence of a dissecting interventricular hematoma that evolves as a fibrotic septal chamber with two separate communications, towards left and right ventricle. This unusual anatomical pattern is generally unsuspected and described as a normal interventricular defect associated with a basal left ventricular aneurysm or pseudoaneurysm. We present a case where echocardiography and ventricular angiography did not detect this situation. As surgical implications are important, this peculiar anatomical pattern should be suspected especially in patients with asymptomatic postinfarction posterior septal rupture or in those with minimal clinical impairment.
In conclusion, systematic off-pump surgery was not associated with a higher rate of mortality, morbidity and cardiac events compared to on-pump technique.
The surgical treatment of ascending aortic and arch aneurysms, even though technically complex and requiring care to avoid neurological sequelae, is well established. Nevertheless, the presence of a significant innominate artery trunk aneurysm implies an adaptation of the surgical options available. We report a case of an aortic aneurysm that involved the ascending aorta, the proximal transverse arch and the brachiocephalic trunk with cranial displacement of the right subclavian and common carotid arteries. This pattern, meant that it was mandatory to change the usual surgical approach. We resected the ascending aorta and the proximal aortic arch replacing them with a dacron prosthesis in a usual fashion. Nevertheless, we were compelled to perform the anastomoses of the innominate trunk branches in an extrathoracic fashion. Furthermore, to ensure an uninterrupted cerebral perfusion, the usual surgical steps were personalized. The anatomical findings, computed tomographic images, surgical technique, cerebral protection and postoperative evaluation are described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
