ABSTRACT
Objective : The mainstream strategy for blunt traumatic thoracic aortic injuries (BTAI) has been shifting from conventional open repair (OR) to thoracic endovascular aortic repair (TEVAR). Accordingly, we reviewed the short- and mid-term outcomes following surgical procedures of BTAI, comparing OR with TEVAR. Methods : We retrospectively collected data of consecutive cases of BTAI in a single institution from March 2001 to August 2019. Results : Eighteen cases were identified. Of these, 7 patients (38.9%, mean age 62.0±15.2 years) were treated with OR and 11 (61.1%, mean age 61.8±21.3 years) were treated with TEVAR. There was significant reduction in the mean operative duration (OR 444±145 vs TEVAR 65±14 min ; p＜0.001), the mean intraoperative blood loss (OR 2,787±1,578 vs TEVAR 210±376 ml ; p＜0.001), the volume of blood transfusions (OR 5,042±2,219 vs TEVAR 929±751 ml ; p＜0.001), and the mean dose of heparin infusion (OR 20.3±4.1 vs TEVAR 7.9±8.5 ml ; p＜0.01). Postoperative 30-day mortality of OR and TEVAR were 28.6 and 0% (p＝0.14), respectively. There was no endoleak, 1 case of paraparesis, and 1 case of bilateral cerebellar infarction in the TEVAR group. There was no significant difference in the length of stay in the intensive care unit, the duration of hospital stay, the rate of home discharge, or the mid-term mortality and re-intervention rate (average follow-up period of 42.0±56.9 months). Conclusions : Compared with OR, TEVAR took less operative time with less bleeding, and required less blood transfusions and heparin. The short- and mid-term outcomes following TEVAR for BTAI was favorable and TEVAR appears to be applicable as a first-line treatment for BTAI.
ABSTRACT
PURPOSE: The efficacy of percutaneous stent implantation for congenital heart disease (CHD) in Korea, where stent availability is limited, has not been determined. This study evaluated the acute and midterm results of stent implantation in different CHD subgroups. METHODS: Stents were implanted in 75 patients with 81 lesions: (1) pulmonary artery stenosis (PAS) group, 56 lesions in 51 patients; (2) coarctation of the aorta (CoA) group, 5 lesions in 5 patients; (3) Fontan group, 13 lesions in 12 patients; (4) ductal stent group, 3 lesions in 3 patients; and (5) other CHD group, 4 lesions in 4 patients. Mean follow-up duration was 2.1 years (0.1–4 years). Medical records were reviewed retrospectively. RESULTS: The minimum lumen diameter (MLD) in PAS and CoA increased from 5.0±1.9 mm and 8.4±1.6 mm to 10.1±3.6 mm and 12.3±2.5 mm, respectively (P<0.01). In the PAS group, pressure gradient decreased from 25.7±15.6 mmHg to 10.4±10.1 mmHg, and right ventricular to aortic pressure ratio from 0.56±0.21 to 0.46±0.19. In the CoA group, the pressure gradient decreased from 50±33 mmHg to 17±8 mmHg. In the ductal stent group, the MLD of the ductus increased from 2.3 mm to 4.3 mm and arterial oxygen saturation from 40%–70% to 90%. No deaths were associated with stent implantation. Stent migration occurred in 3 patients, but repositioning was successful in all. Stent redilation was performed successfully in 26 cases after 29±12 months. CONCLUSION: Percutaneous stent implantation was safe and effective, with acceptable short and mid-term outcomes in Korean CHD patients.

PURPOSE: The purpose of this study was to evaluate the mid-term outcomes of anatomic anterior cruciate ligament (ACL) reconstruction using two anteromedial (AM) portals by comparing with short-term follow-up results. MATERIALS AND METHODS: Fifty patients who were treated by ACL reconstruction using a two AM portal technique were evaluated retrospectively. The follow-up period was at least 5 years. The mean follow-up period was 68.5±13.9 months. The mid-term clinical outcomes were compared with short-term (≥12 months) results. For the assessment of knee stability, anterior tibial translation was evaluated using the Lachman test and the KT-2000. Rotational stability was evaluated using pivot shift test. For clinical assessment, the Lysholm and International Knee Documentation Committee scores were used. RESULTS: The average anterior translation was 2.1±1.4 mm at the short-term follow-up and 2.8±1.8 mm at the mid-term follow-up. Stability and midterm clinical outcomes were not significantly improved compared to the short-term follow-up results. At the mid-term follow-up, anteroposterior (AP) instability assessed by the KT-2000 was slightly increased, but still acceptable. On the other clinical physical evaluation, there was no statistically significant difference. CONCLUSIONS: The short-term and mid-term outcomes of ACL reconstruction using the two AM portal technique were not significantly different except for AP stability although the value was less than 3 mm at both follow-ups. Therefore, this operative technique could be considered a satisfactory alternative for ACL reconstruction.
