Endovascular Stenting for a Crush Injury of the Common Femoral Artery Followed by Open Repair of Unveiled External Iliac Vein Injury after a Horse Fall

Accurate diagnosis and management of a femoral vascular injury is important as it is a life-threatening injury with high morbidity and mortality. This is the case of a 75-year-old man admitted to the emergency room with trauma to the right groin due to a horse fall. Computed tomography showed active bleeding of the femoral artery without pelvic or femoral fracture. We inserted a stent-graft, but hypotension persisted. Exploration of the groin was completed, and the bleeding from the external iliac vein was identified and repaired. In conclusion, vascular injury is rare in groin trauma without associated fracture, however, arterial and venous injury should not be completely ruled out. Endovascular therapy is worth recommending as a quicker and safer management than surgery in patients with active bleeding in the femoral artery. However, the possibility of combined injury of the femoral vein should be suspected in case of ongoing hemodynamic instability.

Comparison of Quality of Life among Patients with Mangled Trauma

PURPOSE: Mangled injury is defined as severe injury, including three or more tissues such as bones, nerves, vessels, muscles, and tendons in the upper or lower extremities. The choice of treatment results in different cosmetic and functional outcomes for mangled injury. In this study, we estimated patients' quality of life after treatment with the future intention of having patients make proper decisions at the time of injury. METHODS: Twenty patients were treated at Asan Medical Center from January, 2009 to November, 2011, and 11 patients were included who agreed with the questionnaire. We used 36-item short form health survey (SF-36) for estimating quality of life after treatments. RESULTS: Subjective satisfaction of cosmetic and functional aspects was higher in the reconstruction group than in the amputation group. However, in the estimation of specified satisfaction using SF-36, the amputation group was more satisfied than the reconstruction group. CONCLUSION: Among the many treatment considerations at the time of injury, expected cosmetic and functional outcomes were important parts determining the decision. In our study, the amputation group showed a better satisfaction level. This result could help patients make more appropriate decisions in the case of mangled injury.

The effect of aromatase inhibitor letrozole incorporated in gonadotrophin-releasing hormone antagonist multiple dose protocol in poor responders undergoing in vitro fertilization

OBJECTIVE: To evaluate whether letrozole incorporated in a gonadotrophin-releasing hormone (GnRH) antagonist multiple dose protocol (MDP) improved controlled ovarian stimulation (COS) and in vitro fertilization (IVF) results in poor responders who underwent IVF treatment. METHODS: In this retrospective cohort study, a total of 103 consecutive IVF cycles that were performed during either the letrozole/GnRH antagonist MDP cycles (letrozole group, n=46) or the standard GnRH antagonist MDP cycles (control group, n=57) were included in 103 poor responders. COS results and IVF outcomes were compared between the two groups. RESULTS: Total dose and days of recombinant human follicle stimulating hormone (rhFSH) administered were significantly fewer in the letrozole group than in the control group. Duration of GnRH antagonist administered was also shorter in the letrozole group. The number of oocytes retrieved was significantly higher in the letrozole group. However, clinical pregnancy rate per cycle initiated, clinical pregnancy rate per embryo transfer, embryo implantation rate and miscarriage rate were similar in the two groups. CONCLUSION: The letrozole incorporated in GnRH antagonist MDP may be more effective because it results comparable pregnancy outcomes with shorter duration and smaller dose of rhFSH, when compared with the standard GnRH antagonist MDP.

The effect of luteal phase progesterone supplementation on natural frozen-thawed embryo transfer cycles

OBJECTIVE: To evaluate the effect of progesterone supplementation during the luteal phase on pregnancy outcome in natural frozen-thawed embyo transfer (FTET) cycles. METHODS: In this retrospective cohort study, 228 consecutive patients who underwent FTET cycles between January 2009 and September 2012 were included. One hundred forty-five patients received luteal progesterone support (P group) but 83 patients did not receive any progesterone supplementation during luteal phase (control group). RESULTS: There were no differences in patients' characteristics between the two groups. The two groups were similar with respect to the characteristics of previous fresh in vitro fertilization cycle in which embryos were cryopreserved including the numbers of oocytes retrieved, mature oocytes, fertilized oocytes, grade 1 or 2 embryos and frozen embryos. Also, significant differences were not observed between the P and control groups in clinical pregnancy rate, embryo implantation rate and multiple pregnancy rate. However, miscarriage rate was significantly lower in the P group and live birth rate was significantly higher in the P group than in the control group (P<0.05, P<0.05). CONCLUSION: Our results suggest that luteal phase progesterone supplementation decreases miscarriage rate and improves live birth rate in natural FTET cycles.
