Recent advances in transthoracic Doppler echocardiography (TTDE) allow for noninvasive, physiological assessment of coronary flow reserve (CFR) in the left anterior descending coronary artery. CFR has been considered as a physiological index of coronary microcirculation in the absence of epicardial coronary narrowing. We demonstrated that whole body periodic acceleration (WBPA) as a passive exercise and remote ischemic conditioning (RIC) whereby repeated brief episodes of ischemia at a site distant from the heart increased CFR values, indicating the potential of WBPA and RIC as new devices for cardiac rehabilitation.
A 26 year-old female diagnosed with nutcracker syndrome was referred to our hospital to undergo stent placement to left renal vein due to progressive anemia and macroscopic hematuria. Ultrasound test and computed tomography before stent placement showed narrowed segment in left renal vein (LRV) between the aorta and the superior mesenteric artery and dilated the hilar LRV portion. Venous pressure gradient in the stenosis LRV was 10 mmHg. Two E-Luminexx stents (12 mm×40 mm) were placed at the stenotic site of the LRV. Patient’s symptom has improved and no postoperative complication has occurred to present.
A 74-year-old man with a 50-mm infrarenal aortic aneurysm was performed endovascular aortic repair (EVAR) under local anesthesia. On EVAR, there were neither significant difficulties nor unstable circulatory dynamics during the procedure. After the procedure, he developed paraplegia immediately. His paraplegia improved by cerebrospinal fluid drainage, steroid administration, and arterial pressure augmentation. At present, he can ambulate with walker after re-habilitation for 3 months. Postoperative magnetic resonance imaging (MRI) showed spinal cord ischemia.
