Résumé
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.
Résumé
Objective:To investigate the effect of somatostatin receptor ligands (SRLs) on bone metabolism in patients with acromegaly.Methods:Retrospective analysis of clinical data of acromegaly patients( n=100) received surgery or SRLs alone for 3 months. The changes of growth hormone (GH), insulin-like growth factor-1 (IGF-1), osteocalcin (OC), N-mid fragment of osteocalcin (N-MID), amino-terminal peptide of type I procollagen (P1NP) and C-terminal peptide degradation product of type I collagen(CTX) were compared before and after treatment. Patients were divided into drug treatment group and surgical group according to treatment methods. According to the decline of GH after medication, patients in the drug treatment group were further divided into drug sensitive group and drug insensitive group. Results:The average dynamic GH and IGF-1 indexes in the drug treatment group were significantly decreased after treatment compared with before treatment (both P<0.05), and CTX was also significantly decreased after treatment [1.25 (0.67, 1.40) ng/mL vs 1.34 (0.57, 1.68) ng/mL, P<0.05]. The mean dynamic GH, IGF-1 index, OC, N-MID, P1NP, and CTX in surgical group were significantly decreased after treatment compared with before treatment (all P<0.01). In the surgical group, there was a positive correlation between GH difference (ΔGH) and N-mid difference (ΔN-MID; r=0.454, P=0.026), and there was a positive correlation between IGF-1 index difference (ΔIGF-1 index) and CTX difference (ΔCTX; r=0.339, P=0.036). After treatment, the mean dynamic GH, IGF-1 index, CTX, P1NP, and N-MID in drug treatment group were significantly higher than those in surgical group (all P<0.001). CTX and N-MID decreased significantly after treatment in drug sensitive group compared with drug insensitive group (35.3% vs 7.2%, P<0.001; 24.1% vs 11.8%, P<0.05), and ΔGH was positively correlated with ΔCTX ( r=0.328, P=0.004). Conclusion:SRLs treatment can reduce bone formation marker N-MID and bone resorption marker CTX, improving the high turnover state of bone metabolism in patients with acromegaly, which may attribute to the reduction of GH and IGF-1 levels.
