<p>Spinal cord injury (SCI) is a main concern in patients who undergo thoracic endovascular therapy (TEVAR), because the blood flow of the vertebro-basilar artery may be reduced due to the left subclavian artery (LSA) occlusion. If the left vertebral artery originates directly from the aorta, which is called the isolated left vertebral artery (ILVA), a technical consideration for strategies regarding blood perfusion of the ILVA during TEVARs is required. We hereby aim to report three patients (No.1, No.2, and No.3) who underwent an ILVA translocation and TEVAR with Zone 2 landing for aortic dissection. The diameter of the ILVA was 4.2, 2.3, and 2.2 mm, respectively, and the right vertebral artery (RVA) was dominant in all cases. In Patient No.1 and No.2 (ILVA diameter: 4.2 and 2.3 mm, respectively), the ILVA was anastomosed directly to the left common carotid artery. In Patient No.2, the translocated ILVA was occluded resulting in SCI, but the SCI improved when blood pressure was augmented. In Patient No.3 (ILVA diameter: 2.2 mm), the saphenous vein graft was interposed between the ILVA and the bypass artery because the ILVA diameter was small, but postoperatively, the ILVA remained patent, and no paraplegia was observed. The occlusion of ILVA could cause SCI, even if the RVA is larger than the LVA. Reconstruction of the ILVA is a critical procedure to prevent postoperative SCIs in patients undergoing TEVARs.</p>

<p>Cardiac tumors are rare, and if malignant, the prognosis is often poor. Specific complications occur depending on the site, and pulmonary tumor embolism is most fatal when the tumor site is in the right heart. Although, surgical intervention does not necessarily improve the prognosis of the tumor itself or survival, surgery can prevent sudden death and improve heart failure symptoms, which in turn is expected to improve the activities of daily living (ADL) and maintain the quality of life (QOL) by allowing hospital discharge. In cases of metastatic tumors or tumors due to progression of liver or kidney cancer, resection of the tumor not only improves ADL and QOL but may also prolong survival and improve prognosis. This study presents five cases of right cardiac malignant tumors in which surgical intervention using cardiopulmonary bypass was performed. In two cases, the patients died early but in the remaining three, relatively longer survival was observed. The patients were discharged and returned home but died later. Postoperative adjuvant chemotherapy may be effective in such cases depending on the tumor morphology. We conclude that surgical intervention was able to prevent sudden death, and a diagnosis followed by adjuvant chemotherapy might extend the survival. On the other hand, early postoperative lung and pulmonary circulatory disorders may be at risk of progressing to DIC and MOF and impairing survival.</p>
