The incidence of cardiovascular disease remains high, and surgery is an important measure for the treatment of cardiovascular disease. However, cardiovascular surgery is complicated and difficult, and it is one of the departments with the highest rate of allogeneic blood transfusion. Allogeneic blood transfusion significantly increases the complications and mortality of patients, while autologous blood transfusion can effectively reduce allogeneic blood transfusion and adverse reactions. Autologous plateletpheresis technology is a popular autotransfusion method in recent years. This article reviews the autologous plateletpheresis technology and its clinical application in cardiovascular surgery.
ObjectiveTo summarize the research progress of mixed reality (MR) technology in the field of vascular surgery.MethodWe retrieved the literatures about the application of MR technology in vascular surgery, and summarized and analyzed them.ResultsThe application of MR technology in vascular surgery could greatly improve the standardization of medical education, shorten the learning cycle, effectively shorten the operation time, and increase the benefit of patients. The application of MR in vascular surgery was still in its infancy, and it showed some attractive prospects as well as some shortcomings.ConclusionsThe application of MR technology in vascular surgery is still at the exploratory stage, but it has an attractive prospect. With the continuous improvement of registration technology and the continuous improvement of accuracy, MR technology will be more and more widely used in vascular surgery.
Abstract： Arginine vasopressin （AVP） is closely related to the pathogenesis of a variety of cardiovascular diseases and kidney diseases. Currently it is often used for the treatment of severe peripheral vasodilatory shock， and particularly beneficial for patients with refractory catecholamine-resistant vasodilatory shock. For some patients who do not have adequate AVP level in plasma after cardiovascular surgery， external low-dose AVP infusion is helpful to decrease the heart rate, and the dosage and duration of catecholamine use. Early initiation of low-dose AVP infusion may be beneficial for postoperative patients’ hemodynamic recovery without adverse complications. More randomized control trials are needed to provide evidence for rational usage， dosage and duration of AVP administration.
Artificial intelligence in robot system is mainly divided into two types: endoscopic robot system and intracavitary robot navigation system. The endoscopic robot system can effectively shorten the time of vascular anastomosis and occlusion during vascular bypass surgery, while the intracavitary robot navigation system has good localization and real-time observation function. Moreover, it has significant advantages in complex lesions and special anatomical locations. High cost and complicated equipment debugging are the main factors that limit the wide application of robot systems. Artificial intelligence represented by robot system has obvious advantages and broad prospects in the field of vascular surgery, but more research is needed to improve its shortcomings and to further clarify its standard operation and long-term results.
目的 探讨四肢动脉损伤的诊断和治疗方法。方法 回顾分析我院1996年1月至2006年7月共诊治的23例四肢动脉损伤患者的临床资料。分别采用直接动脉修补、动脉结扎、端端吻合、自体大隐静脉移植及人工血管吻合。术中取栓6例,合并静脉损伤修复8例。结果 截肢3例（13.0%）。获得随访12例，随访时间3个月~5年，11例多普勒超声证实损伤血管血流通畅，下肢肌肉挛缩1例； 下肢血供不足1例。结论 早期诊断是提高肢体存活率和避免假性动脉瘤发生的关键。手术方式的合理选择、Fogarty导管常规取栓和早期筋膜切开可提高治愈率。
