PURPOSE: Prenatal diagnosis of congenital heart disease has been made by fetal echocardiography and its clinical impact on the outcome of CHD cases has been analysed. METHODS: A prospective study was performed for the fetal diagnosis of CHD for the standard risk pregnancy, confirmed postnatally or at second study and/or at autopsy and/or follow up at CHA hospital in 2001. Incidence of CHD has been calculated and compared to the incidence of CHD of the prescreening period(1992.3-1995.2). RESULTS: There were 66 cases of CHD prenatally during the study period. CHD consisted of 7 cases of ventricular septal defects(VSD), 7 cases of tetralogy of Fallot(TOF), 5 cases of heterotaxy, 5 cases of double outlet right ventricle(DORV), 5 cases of severe pulmonary stenosis(PS), 3 cases of hypoplastic left heart syndrome(HLHS), 3 cases of coarctation, 3 cases of critical aortic stenosis(AS), 3 cases of pulmonary atresia with intact ventricular septum(PA IVS). Among 66 fetal CHD cases, 30 cases of CHD has been terminated, 1 case died in utero and 23 cases has been delivered at cardiac center through planned delivery. The most common factors of termination were extracardiac and chromosomal anomaly. 17 cases of false negative diagnosis were small VSD and mild PS that couldn't be diagnosed in fetal stage. There was no false positive diagnosis. There were 30 cases of CHDs born in 2001 at CHA hospital. 28 cases were diagnosed postnatally. Among 30 cases of CHDs, there were 18 cases of VSD(17 small VSD), 6 cases of mild PS, 4 ASD, 1 PDA. Incidence rate of CHD in 2001 and period 1992.3-1995.2 were 5.95 and 10.15/1,000 livebirth respectively. CONCLUSION: The data suggested that all of the significant CHDs could be diagnosed prenatally accurately by fetal echocardiography. And the incidence rate of CHD has been decreased by 41.4%. And the most of the complex CHD has been transferred to the cardiac center for planned delivery or has been terminated. The rate of termination was 45.5%.

BACKGROUND: The primary goal of this study was to characterize the clinical outcomes of adult patients with hematologic malignancies (HM) who were treated with extracorporeal membrane oxygenation (ECMO) support when conventional treatments failed. METHODS: In this retrospective, observational study at a tertiary medical center, we reviewed the clinical course of 23 consecutive patients with HM requiring ECMO who were admitted to the intensive care unit at Asan Medical Center from March 2010 to April 2015. RESULTS: A total of 23 patients (8 female; median age, 44 years; range, 29–51 years) with HM and severe acute circulatory and/or respiratory failure received ECMO therapy during the study period. Fourteen patients received veno-arterial ECMO, while 9 patients received veno-venous ECMO. The median ECMO duration was 104.7 hours (range, 37.1–221 hours). Nine patients were successfully weaned from ECMO. The in-hospital mortality rate was 91.1% (21 of 23). There were complications in 3 patients (cannulation site bleeding, limb ischemia, and gastrointestinal bleeding). CONCLUSION: ECMO is a useful treatment for patients with circulatory and/or pulmonary failure. However, in patients with HM, the outcomes of ECMO treatment results were very poor, so it is advisable to carefully decide whether to apply ECMO to these patients.

Background:
This study aimed to assess the effect of vessel size and flow characteristics on the maturation of autogenous radiocephalic arteriovenous fistulae (RCAVFs).
Methods:
We retrospectively reviewed records of patients undergoing RCAVF creation at a single medical center from January 2013 to December 2019. Operative variables were compared between patients whose fistulae matured and those whose fistulae failed to mature.
Results:
Overall, 152 patients (33 of whom were women) with a mean age of 62.6±13.6 years underwent RCAVF creation; functional maturation was achieved in 123. No statistically significant differences were observed between patients in whom maturation was or was not achieved in terms of the following variables: female sex (20.3% vs. 25.0%), radial artery size (2.5 vs. 2.4 mm), and pulsatility index (0.69 vs. 0.62). Low intraoperative transit time flowmetry (TTF; 150.4 vs. 98.1 mL/min) and small vein size (2.4 vs. 2.0 mm) were associated with failure of maturation. The best cutoff diameter for RCAVF TTF and cephalic vein size were 105 mL/min and 2.45 mm, respectively.
Conclusion
In patients who undergo RCAVF creation, vein diameter on preoperative ultrasonography and intraoperative TTF are predictors of functional maturation. We identified an intraoperative TTF cutoff value that can be used for intraoperative decision-making.

OBJECTIVE: To evaluate the efficacy of clinical use of a intrauterine Sengstaken-Blakemore tube (S-B tube) in postpartum hemorrhage not controlled with medication and conservative treatment. METHODS: Retrospective review was done in 18 women with insertion of S-B tube into intrauterine cavity who did not controlled with medication and conservative treatment for postpartum hemorrhage. After third stage of labor, women were treated with prophylactic intramuscular Methylergonovine 0.2 mg and intravenous infusions of oxytocin routinely. If the postpartum bleeding continued, Misoprostol 800 microgram (per rectal) and intravenous infusions of Dinoprost 2 mg mixed with 5% D/S 500 cc were employed. And then women were examined for retained placenta and laceration of birth canal. Where necessary, retained placenta was removed and lacerations were sutured. If the postpartum bleeding did not controlled despite all of procedures, we decided use of intrauterine S-B tube. RESULTS: The mean age of the patients was 30.9+/-4.4 (27-39) years, their mean body weights and parities were 67.8+/-8.2 (56.2-85.7) kg, 1.8+/-0.8 (1-4) and mean gestational age was 38.5+/-2.9 (37-42) weeks respectively. The mean time from delivery to insertion of S-B tube was 107.6+/-94.0 (24-360) minutes. The mean filled normal saline amount was 190.5+/-35.2 (120-230) cc. Of 18 who was inserted of S B tube, 15 cases needed not additional surgical therapy. So success rate was 83.3%. CONCLUSION: Insertion of intrauterine S-B tube appears as a simple and effective means of treating postpartum hemorrhage not controlled with medication and conservative treatment.

Trisomy 18 is the second most common chromosomal anomaly which reach to live birth next to Down syndrome. Several methods were proposed to screen patients on the risk of Edward syndrome like maternal serum levels of total human chorionic gonadotropin (hCG), alpha-fetoprotein (AFP) and unconjugated estriol or free beta hCG with AFP, but the serum screening has only 67% detection rate with a 7.2% of false positive rate. Therefore, in order to overcome the limitations which the serum markers have, detailed ultrasound examination is also necessary and sensitivity of 80% was reported. We report a case of Trisomy 18 fetus in which choroid plexus cyst was the only abnormal sonographic finding.

We report a case in which traumatic epistaxis with a carotid cavernous fistula was successfully treated by using radiologic intervention. Since the inner facial bone is an anatomically weak structure and has numerous bleeding sites, traumatic epistaxis is profuse and can not be controlled well by using traditional treatments such as gauze, merocel(R), and foley balloon packing. Uncontrolled epistaxis may cause unstable vital signs and threaten the patient. In the case of failure through traditional treatments, angiographic embolization can be used as a treatment of choice because angiographic embolization can be done at a high success rate with few complications. Stroke, facial palsy, visual loss, and facial pain are the most common complications. In our case, we had tried traditional treatments first, but there was no marked improvement. After the angiographic embolization had been conducted, epistaxis was successfully controlled. The patient 's vital signs were stabilized, and he was admitted to the ICU.

OBJECTIVE: This study was performed to investigate the effects of metformin in PCOS patients undergoing IVF-ET. METHODS: From January 2002 to December 2004, 87 cycles in 32 PCOS patients undergoing IVF-ET at the Infertility clinic of Grace Women's Hospital were randomly divided into two groups and enrolled in this study. The diagnosis of PCOS was made by the criteria from 2003 Rotterdam Consensus. Metformin group (19 patients, 45 cycles) received metformin (Daewoong Pharma Co., Korea; 500 mg three times or two times a day from one or two months before and during IVF cycle) and control group (13 patients, 42 cycles) did not receive metformin. All patients received controlled ovarian hyperstimulation (COH) using gonadotropins (Fostimon, IBSA, Switzerland) with GnRH antagonist (Cetrotide, Serono, Germany). When leading follilces reached 18 mm in diameter, recombinant hCG 250 ?g (OVIDREL, Serono, Italy) was injected. Oocytes were retrieved transvaginally 35 hours later. The luteal phase was supported everyday by progesterone 50 mg IM (Progest, Samil, Korea) with micronized progesterone 200 mg vaginal insertion (Utrogestan, Besins, France). RESULTS: There was no statistical difference in the patients age (34.1+/-3.0 vs 33.5+/-2.9 years), the duration of infertility (4.3+/-1.3 vs 4.5.+/-1.3 years) and BMI (23.5+/-2.4 vs 24.01+/-2.7 kg/m2) among two groups (p> or =0.05 for each). There was also no statistical difference in the indications of IVF among two groups; ovulation factor (27 cycles vs 23 cycles), tubal factor (7 vs 8), male factor (8 vs 7) and other factor (3 vs 4) (p> or =0.05). The duration of ovulation induction in metformin group was significantly shorter when compared with control group (10.1+/-2.3 vs 13.8+/-2.2 days, p<0.05). Total doses of FSH-HP in metformin group were significantly less than that in control group (30.3+/-11.5 vs 39.9+/-11.7 ampules, p<0.05). There was no difference in the number of aspirated oocytes (10.5+/-4.7 vs 9.6+/-3.6), the fertilization rate (65.9+/-17.4% vs 63.2+/-25.9%), implantation rate (30.3+/-11.5% vs 38.1+/-17.3%) and the number of good quality embryo (5.0+/-1.8 vs 4.7+/-2.5, p< or =0.05). Clinical pregnancy rate was higher in metfomin group (33.3% vs. 23.8%), although statistically not significant. CONCLUSION: Although more randomized study is needed, metformin therapy in PCOS patients undergoing IVF has possibility of reducing the duration of COH and the gonadotropin doses.

Journal of Chest Surgery 2024;57(3):272-280
Background:
The phenomenon known as the “weekend effect” impacts various medical disciplines. We compared outcomes between regular hours and off hours to investigate the presence of the weekend effect in extracorporeal cardiopulmonary resuscitation (ECPR).
Methods:
Between January 2018 and December 2020, 159 patients at our center were treated with veno-arterial extracorporeal membrane oxygenation (ECMO) for cardiac arrest. We assessed the time required for ECMO preparation, the rate of successful weaning, and the rate of in-hospital mortality. These factors were compared among regular hours (“daytime”: weekdays from 7:00 AM–7:00 PM), off hours on weekdays (“nighttime”: weekdays from 7:00 PM–7:00 AM), and off hours on weekends and holidays (“weekend”: Fridays at 7:00 PM to Mondays at 7:00 AM).
Results:
The time from the recognition of cardiac arrest to the arrival of the ECMO team was shortest for the daytime group and longest for those treated over the weekend (daytime, 10.0 minutes; nighttime, 12.5 minutes; weekend, 15.0 minutes; p=0.064). The time from the ECMO team’s arrival to ECMO initiation was shortest for the daytime and longest for the nighttime group (daytime, 13.0 minutes; nighttime, 18.5 minutes; weekend, 14.0 minutes; p=0.028). No significant difference was observed in the rate of successful ECMO weaning (daytime, 48.3%; nighttime, 39.5%; weekend, 36.1%; p=0.375).
Conclusion
In situations involving CPR, the time to arrival of the ECMO team was longer during off hours. Furthermore, ECMO insertion required more time at night than during the other periods. These findings warrant specific training in decision-making and emergent ECMO insertion.
