RESUMEN

OBJECTIVE: Paradoxical embolism represents a rare condition occurring when a thrombus originating from venous system produces pulmonary embolism and systemic embolization through an intracardiac or pulmonary shunt. The evidence of a thrombus entrapped in a patent foramen ovale (PFO) is an even more rare condition. There is uncertainty about the optimal treatment strategy. PATIENTS AND METHODS: A 58-year-old male patient was admitted to our Internal Medicine Unit with the diagnosis of bilateral bronchopneumonia. During hospitalization, the co-occurrence of chest pain and amaurosis led us to hypothesize a paradoxical embolism. RESULTS: Transthoracic echocardiography showed the presence of a thrombus stuck over the interatrial septum. A contrast-enhanced chest CT scan showed multiple pulmonary embolisms and brain CT scan documented a hypodense area, of ischemic significance, in the left occipital lobe near tentorium. In order to prevent further embolization, emergency cardiac surgery (right atriotomy, removal of thrombus and closure of the PFO, pulmonary thrombectomy) was performed without complications. CONCLUSIONS: Although rare, the evidence of a thrombus stuck in a patent foramen ovale represents a clinical emergency. The optimal therapeutic approach is still debated. The surgical correction seems to be a safe and effective option for these patients.

RESUMEN

A 49-year-old operated for aortic coartaction patient presented with thoracic and ascending aortic aneurysm. He was asymptomatic. Angio-magnetic resonance nuclear scan and angiography revealed an ascending aortic aneurysm (5.2 cm), bicuspid aortic valve, 6-cm proximal descending aortic pseudoaneurysm at the site of the previous operation with involvement of the left subclavian artery. Restenosis at the original site of coarctation and aortic arch hypoplasia distally to the brachiocefalic trunk was also found. The operation performed was a "modified Bentall - De Bono". The pseudoaneurysm was not accessible through median sternotomy due to the massive lung adhesions following the previous surgery. The left common carotid artery was explanted from the aortic arch and connected with a graft to the ascending aortic conduit. A proximal neck suitable for landing zone of the endovascular stent-graft was then established. The postoperative course was uneventful. After two weeks, the patient was readmitted. The exclusion of the thoracic descending aortic pseudoaneurysm by endovascular implantation of the stent-graft prosthesis was performed. The left subclavian artery was excluded because left vertebral artery was closed. The patient did not develop hand claudicatio. The procedure was successful.

RESUMEN

OBJECTIVE: The optimal treatment of severe monolateral asymptomatic carotid artery stenosis (SMACS) in patients undergoing coronary artery bypass grafting (CABG) is still controversial. MATERIALS AND METHODS: This study is based on the in-hospital and mid-term (>5 years) clinical results of a cohort of 139 consecutive CABG patients with SMACS operated at our Institution between January 1989 and December 1995. In the first 73 patients (no carotid surgery group), the SMACS was left untouched at the time of coronary surgery, whereas in the remaining 66 (carotid endoarterectomy group), the carotid stenosis was treated either immediately before or concomitantly with the CABG procedure (depending on the severity of the anginal symptoms). RESULTS: The overall preoperative characteristics of the patients were comparable. The in-hospital results were similar between the two groups with regard to mortality, stroke and major postoperative complications. However, at mid-term follow-up, significantly more patients of the no carotid surgery group suffered cerebral events (transient or permanent) ipsilateral to the SMACS or the lesion had to be operated on. CONCLUSIONS: The concomitant treatment (either staged or simultaneous) of SMACS at the time of CABG does not influence the in-hospital results, but confers significant neurological protection during the years after the operation.
