A dilated aorta causes a turbulent flow pattern in the aortic arch. The high OSI site was similar to the favourite entry site for acute aortic dissection, indicating the causal relationship between mechanical stress and acute aortic dissection. rSCA cannulation might be cerebroprotective from ascending aortic plaque.

Patients with preoperative LVESVI ranging from 100 to 130 ml/m had fairly better outcomes, and the percentage improvement in LVEF and the percentage reduction in LVESVI were more pronounced in these patients. Hence, accurate preoperative assessments of LV volume and viability testing using cardiac MRI studies are essential for better stratification of the SVR procedure.

RV parameters were more sensitive than LV parameters for predicting worse outcomes following SVR. Preoperative assessment of RV volume and function using cardiac MRI may improve the risk stratification of SVR.

An 89-year-old man complained of pulsatile masses in his right groin. Computed tomography (CT) scans revealed an aneurysm of the right deep femoral artery. He was admitted to our hospital with a diagnosis of deep femoral artery aneurysm (DFAA). The clinical frailty scale score was 6 (moderately frail), and he also suffered chronic obstructive pulmonary disease (COPD). Considering his complicated frail and impaired pulmonary function, conventional graft replacement and aneurysmectomy were thought to be quite a high risk. Thus, we selected endovascular treatment. It was not possible to secure a sufficient proximal landing zone for measurement, we did not select a stent-graft treatment. Therefore, we performed hybrid therapy with proximal neck ligation and distal outflow coil embolization. The postoperative course was uneventful, and CT disclosed complete occlusion of the aneurysm.
