Routine intercostal artery reattachment strategy reduces delayed and permanent spinal cord injury after open descending thoracic and thoracoabdominal aortic aneurysm repair.

Objective: During open descending thoracic and thoracoabdominal aortic aneurysm (DTAA/TAAA) repair, we used a routine T8-T12 intercostal artery (ICA) reattachment strategy from July 2004 to June 2009 and after 2017, we used a selective ICA reattachment strategy (reattaching T8-T12 ICAs only when neuromonitor signals were lost) from July 2009 to 2016. This study reviewed our nearly 2-decade experience to assess the impact of 2 ICA reattachment strategies on spinal cord injury (SCI).

Methods: All open DTAA/TAAA repairs performed from July 2004 to June 2022 were included, except for cases without intraoperative cerebral spinal fluid drainage.

Total Transfemoral Percutaneous Endovascular Aortic Arch Repair Using 3-Vessel Inner Branch Stent-Graft.

Endovascular repair has been introduced to decrease the morbidity and mortality associated with open surgical repair of aortic arch pathology. We illustrate total percutaneous transfemoral approach with a 3-vessel inner branch stent-graft to treat aortic arch aneurysm. ().

Reappraisal of the role of motor and somatosensory evoked potentials during open distal aortic repair.

Objective: Intraoperative motor and somatosensory evoked potentials have been applied to monitor spinal cord ischemia during repair. However, their predictive values remain controversial. The purpose of this study was to evaluate the impact of motor evoked potentials and somatosensory evoked potentials on spinal cord ischemia during open distal aortic repair.

Propensity and impact of autologous platelet rich plasma use in acute type A dissection.

Background: Coagulopathy in patients undergoing open repair of acute type A aortic dissection using cardiopulmonary bypass and hypothermic circulatory arrest is a common complication. Autologous platelet rich plasma is an intraoperative blood conservation technique, which has been shown in previous studies to promote hemostasis, leading to a reduction of blood product transfusions during elective aortic surgery. The purpose of this study is to evaluate the effectiveness of autologous platelet rich plasma as a blood conservation technique during open surgical repair of acute type A aortic dissection.

Removal of heavy metal ions by magnetic chitosan nanoparticles prepared continuously via high-gravity reactive precipitation method.

This study aimed to provide a continuous method for the preparation of magnetic FeO/Chitosan nanoparticles (FeO/CS NPs) that can be applied to efficient removal of heavy metal ions from aqueous solution. Using a novel impinging stream-rotating packed bed, the continuous preparation of FeO/CS NPs reached a theoretical production rate of 3.43kg/h.

Adopting the American anesthesia oral examination in China: value and roadblocks.

The quality and standardized training and certification of young physicians is key to the quality of health care in the future. In contrast to the American system, there is no nationwide and standardized oral examination in the training and certification process for anesthesiologists in China. The adoptability of the American anesthesia oral examination in China, as well as potential roadblocks, has not been specifically discussed.

Autologous platelet-rich plasma reduces transfusions during ascending aortic arch repair: a prospective, randomized, controlled trial.

Background: Blood conservation using autologous platelet-rich plasma (aPRP), a technique of whole blood harvest that separates red blood cells from plasma and platelets before cardiopulmonary bypass with retransfusion of the preserved platelets after completion of cardiopulmonary bypass, has not been studied extensively. We sought to prospectively determine whether aPRP reduces blood transfusions during ascending and transverse aortic arch repair.

Methods: We randomly assigned 80 patients undergoing elective ascending and transverse aortic arch repair using deep hypothermic circulatory arrest to receive either aPRP (n = 38) or no aPRP (n = 42).

Analysis of autologous platelet-rich plasma during ascending and transverse aortic arch surgery.

Background: Coagulopathy is a common complication after ascending and transverse arch aortic surgery with profound hypothermic circuit arrest (PHCA). Blood conservation strategies to reduce transfusion have been ongoing and involve multiple treatment modalities in modern cardiac surgery. The purpose of this study is to evaluate the effectiveness of autologous platelet-rich plasma (aPRP) as a blood conservation technique to reduce blood transfusion in ascending and arch aortic surgery.
