Treating a thoracic aortic aneurysm (TAA) after coronary artery bypass graft (CABG) surgery requires an appropriate surgical procedure to preserve the functional graft. We present a case of hybrid procedure of thoracic endovascular aortic repair combined with a redo off-pump CABG via median sternotomy. The patient was a 76-year-old man with a history of CABG and abdominal aortic replacement in a different country. Chest computed tomography revealed a saccular-shaped aortic aneurysm in the distal aortic arch with diameter of 5.6 cm. Coronary angiography revealed theLIMA graft was patent but anastomosed to the diagonal branch and the left anterior descending artery (LAD) was totally occluded and was opacified through the right coronary artery. Significant ischemic change in the anteroseptal wall suggested a requirement of surgical revascularization of LAD. The chest was opened via re-midsternotomy. Then the 3 arch vessels were reconstructed with a trifurcated artificial graft attached to the ascending aorta and coronary artery bypass grafting was performed on the beating heart. Finally, the aneurysm was excluded by introducing a stent graft through the graft to zone 0. The patient's postoperative course was uneventful and he was discharged on postoperative day 16. A hybrid procedure via median sternotomy was useful in the surgery for TAA with the functional LIMA after CABG.

BACKGROUND:
Placenta previa and placenta accreta associate with high morbidity and mortality for both mothers and fetus. Metal exposure may have relationships with placenta previa and placenta accreta. This study analyzed the associations between maternal metal (cadmium [Cd], lead [Pb], mercury [Hg], selenium [Se], and manganese [Mn]) concentrations and placenta previa and placenta accreta.
METHODS:
We recruited 17,414 women with singleton pregnancies. Data from a self-administered questionnaire regarding the first trimester and medical records after delivery were analyzed. Maternal blood samples were collected to measure metal concentrations. The subjects were classified into four quartiles (Q1, Q2, Q3, and Q4) according to metal concentrations.
RESULTS:
The odds ratio for placenta previa was significantly higher among subjects with Q4 Cd than those with Q1 Cd. The odds ratio for placenta previa was significantly higher for subjects with Q2 Pb than those with Q1 Pb.
CONCLUSION
Participants with placenta previa had higher Cd concentrations. However, this study was cross-sectional and lacked important information related to Cd concentration, such as detailed smoking habits and sources of Cd intake. In addition, the subjects in this study comprised ordinary pregnant Japanese women, and it was impossible to observe the relationship between a wide range of Cd exposure and placenta previa. Therefore, epidemiological and experimental studies are warranted to verify the relationship between Cd exposure and pregnancy abnormalities.
