The incidence of postoperative pulmonary torsion is not frequent but it has a high mortality rate once it occurs, and prompt diagnosis and treatment are required. From past reports, it is considered effective to point out disruption of pulmonary blood flow by contrast-enhanced computed tomography (CT) examination for diagnosis. However, the comparison of pre- and post-operative plain CT images is considered to be useful in diagnosing lung torsion, and postoperative CT lung window setting sagittal images were examined in three cases of postoperative lung torsion. Results indicate that pulmonary torsion of the middle lobe after right lower lobectomy and the middle lobe after right upper lobectomy can be diagnosed by the present method.Pericardial adhesions can pose serious problems during cardiac reoperation. Here, we report three cases where circular pericardial drainage (CPD) was performed during the initial surgery and no pericardial adhesions were found during reoperation. All three patients had initially undergone an aortic valve replacement with CPD. Case 1An 80-year-old female was reoperated this time for an aneurysm of the ascending aorta. A replacement of the ascending aorta was performed. Case 2A 76-year-old male underwent a second aortic valve repair indicated for prosthetic valve infection. Case 3The patient was an 82-year-old female. This time, mitral valve replacement, indicated for severe mitral valve stenosis, was performed. In these three cases, there were almost no adhesions in the CPD route. The diaphragmatic pericardial surface, the oblique sinus of pericardium, and the lateral side of the left ventricle were also adhesion-free. CPD can effectively drain postoperative pericardial hemorrhage and thus prevent pericardial adhesions.
Performing sternal reconstruction after a median sternotomy using a corrugated bioresorbable sheet composed of poly-L-lactide acid and hydroxyapatite can improve the safety and efficacy of the treatment outcome and promote bone healing.
We compared treatment outcomes of 53 patients who underwent sternal closure using a corrugated sheet (group P) from October 2018 with retrospectively evaluated outcomes of 57 patients who underwent sternal closure using a sternal pin-type device( group C).
Sternal wound infection was not observed in either group. Significant sternal dehiscence was not observed in group P, but it was seen in three cases in group C( p=0.0449). Incomplete approximation by wire cutting was observed in 3% of patients in group P and 15% of patients in group C( p=0.0645). Displacement in the antero-posterior direction was 1.35 mm in group P and 1.67 mm in group C (p=0.0707). The drain discharge volume during 12 hours after operation was 175 ml for group P and 220 ml for group C (p=0.1958), while the total drain discharge volume was 380 ml for group P and 622 ml for group C( p=0.0068). The mean hospital stay was 23.9 days for group P and 26.3 days for group C( p=0.3637).
The total volume of drain discharge significantly decreased when a bioresorbable corrugated sheet was used for sternal closure. We also consider that the bioresorbable corrugated sheet may improve repair of the split sternum and could result in decreased sternal dehiscence.

Thirty patients who had aortic stenosis and underwent transapical TAVI between 2016 and 2020 were enrolled. Medical records were reviewed, and the following data were retrieved and analyzedbasic demographic data, and intraoperative data and postoperative outcomes. Mean age was 85.8 years. There were 3 intraoperative complications (1 apex bleeding, 1 coronary stenosis and 1 mitral regurgitation). Extracorporeal membrane oxygenation was initiated due to unstable hemodynamics in two patients. One patient was converted to mitral valve replacement due to severe mitral regurgitation. There were 2 in-hospital complications (1 with sick sinus syndrome and 1 with cerebral infarction). check details One patient died of cerebral infarction and eventually, the 30-day mortality was 3%. Median observational period was 1.3 years. Three-year survival was 87.3%. Left ventricular ejection fraction increased by six months after the procedure and then, reached plateau. Left ventricular mass index decreased constantly throughout the observational period. Both parameters at one year after the procedure were significantly higher than preoperative ones. In conclusion, survival after transapical TAVI was favorable because of the low critical complication rate. Both left ventricular functional improvement and reverse remodeling were obtained.
This study aimed to consider the safety and feasibility of uniportal video-assisted thoracic surgery( VATS)[ u-VATS] compared with multiportal VATS( m-VATS).
Sixty-two patients underwent anatomical lung resection for primary lung cancer via u-VATS between February 2019 and May 2020 at our institution. We performed propensity score matching of these cases versus anatomical lung resection cases under m-VATS performed from January 2017 to December 2019, and compared the perioperative results.
In the u-VATS group, operation time( 142 minutes vs. 178 minutes, p<0.01) and postoperative drainage days( 1.6 days vs. 2.4 days, p=0.01) were significantly shorter. There were no differences in intraoperative blood loss, vascular damage, conversion rate, number of lymph nodes dissected, postoperative complications, and postoperative hospital stay. The number of pain complaints and the number of analgesics (non-steroidal anti-inflammatory drugsNSAIDs) prescribed at the first outpatient clinic after discharge were significantly lower in the u-VATS group( 10 vs. 22, p=0.03).
U-VATS shortened the operation time and postoperative drainage period compared with conventional m-VATS, and significantly reduced the use of analgesics. U-VATS is considered to be safe and less invasive surgical procedure based on the present study.
