Fast-track protocol of endovascular aneurysm repair for ruptured abdominal aortic aneurysm / 中国医师进修杂志

Objective:To analyze the effective and safety of endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysm (RAAA) at one tertiary center, and to improve the outcomes of RAAA under fast-track protocol.Methods:Nineteen cases of RAAA in the 940th Hospital of Joint Logistic Support Force of PLA from January 2014 to December 2020 were reviewed retrospectively. EVAR-fist strategy was employed from the emergency room to the operating room by using fast-track protocol. Preoperative management, anatomic characteristics, choice of anesthesia, operative procedures and postoperative complications were collected and analyzed. Abdominal compartment syndrome (ACS) and hospital mortality were paid special attention.Results:Nineteen cases were undergone EVAR procedures. The age was (73.4 ± 7.4) years old, and the AAA size was (67.8 ± 13.6) mm. Two cases underwent cardiopulmonary resuscitation at emergency department. General anesthesia was used in 13 patients and local anaesthesia in 6 patients. Successful stent graft deployment was achieved in all cases. The duration from emergency room to operating room was (84.8 ± 22.4) min. The hospital stay time was (9.7 ± 5.7) d. The hospital mortality was 5/19. The 5 deaths were reviewed: 3 died for multiple organ failure, 1 for irreversible shock, and 1 for ongoing bleeding.Conclusions:Excellent results were confirmed by using EVAR-first strategy for RAAA. The management of hemodynamically unstable state, standardized endovascular procedure, fast-track program and multidiscipline team collaboration were the very important determining factors for the implementation of EVAR. Focused efforts to reduce RAAA mortality are warranted.

DeBakey Ⅲ dissecting aneurysm treated by way of aortic isolation / 中国综合临床

Objective To study the technical skill and therapeutic effect of aortic isolation for treating DeBakey Ⅲ dissecting aneurysm.Methods Among 20 cases of DeBakey Ⅲ dissecting aneurysm,7 cases were with DeBakey Ⅲ a and 13 cases were with DeBakey Ⅲb.Imaging examinatin showed that among the 20 cases there were 5 cases with more than two tearings at difreret site.Covered stent was used to close left subclavian artery in 7 cases and distaI aortic isolation of left subclavian artery was conducted in other 13 cases.Restuls All cases were followed up for 3-40 months,finding that 19 cases survived but one case died because of pseudocoele bronchial fistula hemoptysis 18 months later.Conclusions Endovasular covered stent grafts is the simple,safe and effective way to treat dissecting aneurysm.

ADENOVIRUS-MEDIATED GENE TRANSFER OF VASCULAR ENDOTHELIAL GROWTH FACTOR B INDUCES PROLIFERATION OF VASCULAR ENDOTHELIAL CELLS / 解放军医学杂志

To investigate the effect of transfection of adenovirus mediated vascular endothelial growth factor B (VEGF B) gene transfer on the proliferation of endothelial cells. We constructed a replication deficient recombinant adenovirus vector coding for human VEGF B, and detected its gene transcription and expression in Ad. VEGF B infected rat arotic endothelial cells (RAECs) with RT PCR and western blat. The effect of Ad.VEGF B on RAECs prolifeation was examined by MTT assay on days 1, 2, 3, 5, 7 after infection. RAECs were successfully infected with high efficiency and expressed a special protein that is immunoreactive to anti VEGF B monoclonal antibody. This protein could be detected in the culture medium. The proliferation assay of RAECs infected with VEGF B expressing adenovirus revealed a significant increase in cell number over control. These results implied that the use of VEGF B expressing recombinant adenovirus may induce angiogenesis, which might be potential in vivo gene therapy for ischemic heart disease.
