Résumé
We report a 30 year old female admitted with a story of right upper quadrant pain and previous hepatic surgery for hydatid disease. A thoracoabdominal angio CAT sean and transesophageal echocardiogram revealed a mass located in the right atrium. The patient was operated and the right atrial mass was excised. Pathological study of the surgical piece confirmed a hydatid cyst. Post operative recovery was uneventful.
La hidatidosis es una zoonosis parasitaria, de mayor incidencia en el sur de Chile. Su localización más frecuente es hepática y pulmonar. Sus complicaciones derivan de su crecimiento y afección de estructuras adyacentes o de su ruptura a cavidades. Presentamos un caso de quiste hidatídico hepático complicado, en una paciente que debutó con cuadro de dolor abdominal localizado en hipocondrio derecho producto de una lesión quística hepática con comunicación a vena cava inferior, siendo intervenida en su hospital de origen. Posteriormente AngioTAC y ecocardiografía transesofágica confirmaron masa intra auricular. Se realizó extracción de la masa bajo paro circulatorio con hipotermia profunda, correspondía a membranas hidatídicas y trombos adheridos a ella. La paciente evolucionó satisfactoriamente.

Background: When the ascending aorta and the femoral artery cannot be used for extracorporeal circulation, an emerging alternative is the use of axillary artery. Aim: To report the experience using the axillary artery for extracorporeal circulation. Patients and methods: Between November 1998 and May 2002, 22 patients (14 male) were operated with extracorporeal circulation, cannulating the axillary artery. Briefly, an incision is made below the middle third of the clavicle and a cut is made on major pectoris muscle. Minor pectoris muscle is retracted and axillary artery is exposed. It is cannulated directly or with the aid of a prosthesis. Results: Right axillary artery was used in 21 patients and in 20 it was cannulated with the aid of a prosthesis. Mean flow was 4.5 + 0.6 l/min. The most common indications were aortic dissection or aneurysms. The most common procedures done, were ascending aorta replacement in 8 cases and replacement of ascending aorta and aortic arch in 5. Thirty five percent of operations were emergencies and 32 percent were reoperations. In 15 patients (68 percent), a circulatory arrest was done. Of these, retrograde brain perfusion was used in 9, antegrade brain perfusion through the same axillary artery was used in 2 and mixed perfusion was used in 2. One patient had a complication related to the axillary cannulation. None had cerebrovascular accidents or thromboembolic complications. Two patients died in the postoperative period. Patients were followed up to 42 months after the procedure and no secondary complications of the cannulation were detected. Conclusions: When the ascending aorta and the femoral artery cannot be used, axillary artery is a good alternative for extracorporeal circulation
