RESUMO
We report the repair of a double aortic arch, coarctation of the aorta, and left subclavian artery (LSCA) aneurysm using a hybrid procedure in a 47-year-old woman. The patient underwent repair through a median sternotomy incision to bypass the left common carotid artery and LSCA. An endovascular approach was used to repair the coarctation of the aorta and to occlude the right aortic arch. Repair of this anomaly was advised because of worsening clinical symptoms and potential for fatal rupture or dissection of the LSCA aneurysm. Hybrid repair simplified what would have required a multistage open repair.
RESUMO
BACKGROUND: Internal jugular vein extracorporeal membrane oxygenation (ECMO) cannula position is traditionally confirmed via plain film. Misplaced cannulae can result in need for repositioning and increased morbidity. Echocardiography (ECHO) may be used during cannulation as a more accurate means of guiding cannula position. This study reviews the effect of a protocol encouraging the use of ECHO at cannulation. METHODS AND MATERIALS: Single institution retrospective review of patients who received ECMO support using jugular venous cannulation. We compared those who underwent ECHO (ECHO+) at the time of cannulation with those who did not (ECHO-). RESULTS: Eighty-nine patients were included: 26 ECHO+, 63 ECHO-. Most ECHO+ patients underwent dual-lumen veno-venous (VV) cannulation (65%); 32% of ECHO- patients had VV support (P = 0.003). There was no difference in the rate of cannula repositioning between the two groups: 8% ECHO+ and 10% ECHO-, P = 0.78. In the VV ECMO subgroup, ECHO+ patients required no repositioning (0/17), while 20% (4/20) of ECHO- VV patients did (P = 0.10). After cannulation, there were 0.58 ECHO studies per patient to verify cannula position in the ECHO+ group compared with 0.22 in the ECHO- group (P = 0.02). Each group had a major mechanical complication: atrial perforation from a guidewire during cannulation in ECHO+ and late atrial perforation from a loose cannula in ECHO-, and there was no difference in minor complications. CONCLUSIONS: ECHO guidance during neonatal and pediatric jugular cannulation for ECMO did not decrease morbidity or reduce the need for cannula repositioning. ECHO may still be a useful adjunct for precise placement of a dual-lumen VV cannula and during difficult cannulations.
