Background: The aim of this study was to compare the early outcomes of octogenarians undergoing minimally invasive right anterior mini-thoracotomy aortic valve replacement (RAT-AVR) with those undergoing transcatheter aortic valve implantation (TAVI) for aortic valve disease. Methods: In this single-center retrospective study, data were collected from octogenarians before and after RAT-AVR and TAVI between January 2021 and July 2022. Short-term outcomes, including the length of hospital stay, in-hospital mortality, all-cause mortality, and other major postoperative complications, were compared and analyzed. Results: There were no significant differences in in-hospital mortality, stroke, acute kidney dysfunction requiring renal replacement therapy, length of intensive care unit stay, or length of hospital stay. However, the TAVI group had a higher incidence of permanent pacemaker insertion (10% vs. 0%, p=0.54) and paravalvular leaks (75% vs. 0%, p<0.001). Conclusion In the present study on octogenarians, both TAVI and RAT-AVR showed comparable short-term results. Although both procedures were considered safe and effective in the selected group, RAT-AVR had a lower incidence of complete atrioventricular block and paravalvular regurgitation.

Background: Aortic valve replacement (AVR) has recently been performed at many centers using a minimally invasive approach to reduce postoperative mortality, morbidity, and pain. Most previous reports on minimally invasive AVR (MiAVR) have mainly focused on aortic stenosis, and those exclusively dealing with aortic regurgitation (AR) are few. The purpose of this study was to investigate early surgical results and review our experience with patients with chronic severe AR who underwent AVR via right anterior mini-thoracotomy (RAT). Methods: Data were retrospectively collected in this single-center study. Eight patients who underwent RAT AVR between January 2020 and January 2024 were enrolled. Short-term outcomes, including the length of hospital stay, in-hospital mortality, postoperative complications, and echocardiographic data, were analyzed. Results: No in-hospital mortalities were observed. Postoperative atrial fibrillation occurred temporarily in three patients (37.5%). However, none required permanent pacemaker implantation or renal replacement therapy. The median values of ventilator time, length of intensive care unit stay, and hospital stay were 17 hours, 34.5 hours, and 9 days, respectively. Preoperative and postoperative measurements of left ventricular ejection fraction were similar. However, the left ventricular end systolic and diastolic diameters significantly decreased postoperatively from 42 mm to 35.5 mm (p=0.018) and 63 mm to 51 mm (p=0.012), respectively. Conclusion MiAVR via RAT is a safe and reproducible procedure with acceptable morbidity and complication rates in patients with chronic severe AR. Despite some limitations such as a narrow surgical field and demanding learning curve, MiAVR is a competent method for AR.

We report very rare case of concurrent bronchial atresia and bronchogenic cyst. Morphologic apical segment of right upper lobe directly stemmed from right main bronchus. Bronchogenic cyst was communicating with atretic segmental bronchus and both were filled with mucus. The etiology is not well known, however it is likely that a single insult arround the 5th~6th week causes both malformations.

Splenosis is defined as the autotransplantation of splenic tissue after a traumatic splenic injury or a splenectomy. It has often been mistaken as an endometriosis, an intraperitoneal carcinoma, a hemangioma and an accessory spleen. It is clinically significant in that it requires no treatment if it is asymptomatic. Here we report a case of 34 year-old woman who had a pelvic splenosis with cyclic abdominal pain for several years, which was initially misdiagnosed as ovarian dermoid cyst. At the time of exploration, a splenosis was observed in the pelvic cavity. After surgery, a multiple splenosis in the abdominal cavity was found through a Tc-99m heat denatured red blood cell scan. The removal of the splenosis in the pelvic cavity resulted in an improvement in her symptoms.

BACKGROUND: The goal of acute myelogenous leukemia(AML) therapy is to obtain the complete remission(CR) and to improve disease-free survival. Advances in chemotherapy and supportive care provided significant improvement in CR rate up to 60~85% patients with AML. METHODS: Forty two patients with previously untreated AML at Yeung Nam University Hospital from April 1985 through November 1996 were treated with AD(7-3) regimen for induction chemotherapy and followed by two courses of consolidation with AD(5-2) regimen. And the authors analyzed clinical factors related to the CR and overall survival. RESULTS: Twenty-four of the 42 patients achieved CR, and median duration of remission in 24 patients achieved CR was 56 weeks(4~ 305 +weeks). Median duration of survival in all 42 cases was 46 weeks(2~340 + weeks), and in 24 cases achieved CR was 73 weeks(12~340 +weeks). Causes of induction failure included infection in 9 cases, bleeding in 3 cases and drug resistance in 6 cases. Among the potential prognostic variables including age, initial WBC count, performance status, and presence of Auer rods and infection at the time of diagnosis, none was statistically significantly related to the prognosis. CONCLUSION: Further clinical trials for effective remission induction and postremission chemotherapy are necessary to overcome drug resistance and to increase the CR rate and duration.

BACKGROUND/AIMS: Functional dyspepsia (FD) is characterized as chronic recurrent upper gastrointestinal symptoms in the absence of any organic disorder. We hypothesized that duodenal low-grade inflammation activates superficial afferent nerve sprouting, thereby contributing to hypersensitivity in patients with FD. METHODS: A prospective case-control study was conducted in a tertiary referral center. FD was defined using the Rome III criteria. Standardized endoscopic biopsies were performed in the stomach and duodenum. Hematoxylin and eosin staining and immunohistochemical staining for major basic proteins were performed to detect granulated eosinophil-derived granules, and S-100 staining was performed to detect fine nerve fibers. RESULTS: A total of 51 patients with FD (82% female; mean age 35.8 ± 13.4 years) and 35 controls were enrolled. Activated eosinophil counts in the duodenum were significantly higher in patients with FD than in controls (41.4% vs 17.1%, P = 0.005). Microscopic duodenitis was more frequently detected in patients with FD than in controls. Fine nerve fibers were more abundant in patients with FD than in controls (45.1% vs 11.4%, P = 0.029). The abundance of fine nerve fibers highly correlated with the degree of activated eosinophils. CONCLUSION: Duodenal low-grade inflammation, such as mucosal eosinophilic accumulation with degranulation, promoted mucosal enteric nerve fiber density and sprouting in patients with FD.

Lemierre's syndrome is characterized by a rare fulminant condition resulting from primary oropharyngeal infection followed by secondary septic thrombophlebitis of the internal jugular vein and metastatic infection. A forty-year-old man who had been on ventilator due to severe chest trauma, showed severe reddish inflammatory swelling of the right cervical soft tissue and newly developed pneumonia. He went into in septic condition shortly thereafter. Thrombophlebitis with central abscess in the right internal jugular vein was identified by neck CT and MRA(magnetic resonance angiography). Right cervical swelling worsened in spite of clindamycin and heparin therapy. We performed immediate surgery for removal of septic thrombus and resection of internal jugular vein. Patient's septic condition, pneumonia, and local inflammatory reaction were improved within several days after surgery.

Aortic dissection after aortic valve replacement(AVR) is rare, but it is considered a definite disease entity. It's risk factors are a dilated ascending aorta(>or=50 mm) at the time of AVR, hypertension, and thin fragile aortic wall. We report the surgical treatment of a patient who had ascending aortic dissection 7 years after having undergone AVR due to aortic regurgitation associated with a dilated ascending aorta(50mm in outer diameter).

BACKGROUND: To evaluate the efficacy of arterial switch operation for transposition of great arteries, serial echocardiographic studies were performed in 8 patients who underwent the surgery between 1989 and 1998 at Dept. of Thoracic & Cardiovascular Surgery, Yeungnam University Hospital in Daegu City, Korea. MATERIAL AND METHOD: Follow-up period ranged from 6 months to 11 years(average of 4.1 years). Body weight ranged from 2.6kg to 4.8kg, with average of 3.6kg. 5 of 8 patients were preoperatively diagnosed as TGA+VSD, and 3 as TGA+IVS. LV function was evaluated by the measurement of LV shortening fraction, LVSTI, and LVEF. RVSTI was also measured. Postoperative function of valve and growth of great vessels were analyzed by the measurement of PSPGV, valvular regurgitation, LA/AO ratio, root dimension of aorta and pulmonary artery, comparing with the age matched controls, respectively. RESULT: LVEF had an average of 65.0+/-9.03% which is tended to increase serially. LVAOPG had an average of 15.9mmHg. RVPAPG, 27.5mmHg. From the measurement of aortic root dimension of 6 patients at end-systole, aortic root growth was assumed to increase more than the mean value of normal growth. PA root dimension at end-systole showed a similar growth progress when compared with age matched normal controls. Postoperative pulmonic valve regurgitation was noted in 5 of total 8 patients, in which 1 patient who showed grade 2 and 4 showed below grade 1. AR, in 6 patients and all grade 1. Except 1 patient, all the valvular regurgitations were below grade 1, which was presumed to be clinically insignificant. CONCLUSION: LV function after arterial switch operation was maintained relatively well. Mild neoaortic stenosis was noted. Neopulmonary stenosis and regurgitation were less than moderate degree and surgical correction was not deemed to be necessary. Growth progress of aortic root was above normal than controls and PA root growth was similar to the normal controls, postoperatively. However, further change and refinement of surgical technique will decrease the incidence of neopulmonary stenosis and regurgitation.
