limb ischemia was similarly 13%. The reason for the greater presentation of acute limb ischemia and major amputation after stent graft thrombosis was likely due to obliteration of the collateral channels coming off the stented segment.The average lesion length in this study was 26 cm. After implantation of the stent-grafts, dual antiplatelet therapy was prescribed for 6 months, with a recommendation for maintenance for 12 months unless contraindicated. The patients underwent duplex ultrasound every 3 months after the procedure, which we agree is a useful surveillance tool for Viabahn stent-grafts. 2 Among the patients who had undergone reintervention in this study, 56% had undergone endovascular intervention, 29% had undergone surgical thrombectomy, and 15% had undergone bypass surgery. Because the patency was comparable between the surgical and endovascular intervention groups and because the perioperative complications were greater with surgery, the authors recommended endovascular intervention as the first-line strategy for revascularization of a thrombosed stent-graft. However, the 54% 1-year patency after reintervention in this study was poor. Although choosing the type of intervention can be difficult and depends on the acuity of the symptoms, performing autologous vein bypass (when possible) will yield better long-term results and avoid the potentially catastrophic complications of distal emboli associated with mechanical thrombectomy and thrombolysis of a thrombosed stent-graft.

Yin Yang et al.: Rapid Rehabilitation Surgery in Anesthesia Rapid rehabilitation surgery, also known as accelerated rehabilitation surgery, is a series of perioperative optimal management measures based on evidence-based medicine, in order to minimize the perioperative stress reaction of patients and reduce the risk of various complications, so as to achieve the goal of improving prognosis and promoting rapid recovery of patients. The concept of rapid rehabilitation surgery plays an important role in clinical anesthesia. It runs through the whole anesthetic work, such as preoperative anesthetic health education, preoperative fasting, selection of anesthetic scheme, intraoperative fluid therapy, intraoperative body temperature monitoring, postoperative analgesia and perioperative anesthetic management. The following article will review the application progress of rapid rehabilitation surgery in clinical anesthesia in recent years.
