Ji Hyo Kim and Ji Hyun Kim contributed equally to this work and also co-first authors. Vascular injuries during total hip arthroplasty (THA) are rare, but they could be life threatening when they occurs. Therefore, early diagnosis and appropriate management should be required to reduce the rate of morbidity and mortality of the patient. In case of external iliac vein (EIV) injury, it could be more difficult to be noticed because of its slow onset, which could result in cata strophic, delayed hemorrhagic shock. Although EIV injury during THA is uncommon and has not been emphasized enough in anesthetic field, subsequence could be fatal. Herein, we report a case of EIV injury occurred by a drill tip passing through the acetabulum during THA. The patient showed an abrupt hemodynamic collapse without visual evidence of massive bleeding. Cardio pulmonary resuscitation was even required before detection and repair of EIV.
Ji Hyo Kim和Ji Hyun Kim对这项工作做出了同样的贡献，也是共同第一作者。全髋关节置换术中血管损伤是罕见的，但一旦发生可能危及生命。因此，需要早期诊断和适当的管理，以降低患者的发病率和死亡率。对于髂外静脉(EIV)损伤，由于其起病缓慢，较难发现，可导致失调性迟发性失血性休克。尽管全髋关节置换术中的EIV损伤并不常见，在麻醉领域也没有得到足够的重视，但其后果可能是致命的。在此，我们报告一例髋臼置换术中钻尖穿过髋臼造成的EIV损伤。患者表现为突然的血流动力学塌陷，没有明显的大出血迹象。在发现和修复EIV之前，甚至需要心肺复苏。

Prophylactic anticoagulation for high-risk patients of pulmonary embolism (PE) prevails as acute PE potentially leads to hemodynamic instability resulting in death. Notwithstanding the adequate thromboprophylaxis, rarely, we may face a patient ’ s critical condition with PE. We report here on the patient given intraoperative cardiopulmonary resuscitation that the cause was revealed to be PE despite subcutaneous anticoagulant until the day before scheduled secondary operation. The 72-year-old male patient had already undergone first emergency surgery for right tibia and patella fractures without any problems. Albeit effective, prophylaxis for thromboembolism cannot guarantee PE prevention. With this sobering fact in mind, addi-tionally, early diagnosis and prompt management of PE, especially through interdepartmental coordination, should produce patients ’ best outcomes.

We selected 182 patients who could be observed for at least 1 year from among 352 patients who received surgical treatment for osteoporotic isolated femur intertrochanteric fractures between January 2013 and December 2016. The PFNA II was applied in 110 cases, and the ZNN in 72 cases. We evaluated operation time, bleeding amount, quality of reduction, tip apex distance, bone union time, sliding distance, and lag screw position. The mean operation times and bleeding volumes were respectively 38 minutes and 224 mL for PFNA II, and 42 minutes and 234 mL for ZNN. The quality of reduction was good, acceptable, and poor in 71%, 25%, and 4% for PFNA II, and 68%, 31%, and 1% for ZNN, respectively. The mean tip apex distances, bone union times, and sliding distances were respectively 21.1 and 20.7 mm, 12.4 and 12.9 weeks, and 4.2 and 3.9 mm. The lag screw position was acceptable and poor in 95% and 5% for PFNA II, and 97% and 3% for ZNN, respectively. The design of the lag screw did not influence the surgical outcome in the osteoporotic isolated femur intertrochanteric fractures. Therefore, choice of the proximal femoral nail can safely be made according to surgeon preference.

Surgical procedures, as well as anesthetics, affect stress hormones and proinflammatory cytokines. Therefore, we investigated the effect of two different anesthetic techniques on intraoperative hormonal stress responses and interleukin-6 (IL-6) in patients with chronic renal disease undergoing arteriovenous fistula formation. Eighteen patients aged above 20 years were randomly divided into two groups: group A (n=8) with axillary brachial plexus block and group MAC (n=10) with monitored anesthesia care (MAC) using dexmedetomidine. The levels of epinephrine, norepinephrine, cortisol, glucose, IL-6, and heat shock protein 70 (HSP70) were recorded at pre-anesthesia (T0) and end of surgery (T3). No significant differences in epinephrine and HSP70 were observed between these two groups or within each group. Norepinephrine was significantly decreased in group MAC compared with group A at T3 (p=0.001), but no significant differences were found within each group. The cortisol level in group MAC significantly decreased at T3 compared with T0 (p=0.028). The glucose level in group MAC significantly increased at T3 compared with T0 (p=0.019). No significant differences in IL-6 levels were observed within each group. In conclusion, in this study, neither monitored anesthesia nor regional anesthesia influenced stress hormones and proinflammatory cytokines in patients undergoing arteriovenous fistula formation, but significant changes in cortisol and glucose levels were observed in the group receiving dexmedetomidine.

It is a rare disease reported with one per million in the world every year. We experienced a 68-year-old female patient of spontaneous spinal subarachnoid hematoma with unknown origin that the patient admitted to emergency medical center due to non-particular symptoms and the disease was accidentally discovered after various tests and examinations, and then the emergency surgery was conducted.

Myocardial viability is one of important factors to determine clinical outcomes after off-pump coronary artery bypass grafting. We hypothesized that the revascularization of nonviable myocardium might show the different features of myocardial reperfusion postoperatively as compared with viable myocardium. Patients who underwent off-pump coronary artery bypass grafting for 2 years were retrospectively reviewed. Viable group (V group, n=159) and nonviable group (N group, n=24) were divided using preoperative single photon emission-computed tomography. The postoperative complication was evaluated by 1) occurrence of rhythm disturbance (atrial fibrillation/flutter or ventricular tachycardia), 2) use of continuous epinephrine, and 3) intra-aortic balloon pump insertion. Intubation time and intensive care unit (ICU) stay were also documented. Demographic data (gender, age, ejection fraction, and New York Heart Association [NYHA] classification) showed no difference. N group showed higher incidence of rhythm disturbance. Although intubation time showed no difference, ICU stay of N group was longer than V group. Revascularization of non-myocardium was associated with higher incidence of rhythm disturbance and longer ICU stay as compared with viable myocardium.
