Cabrol's technique was performed on a patient with corrected transposition of the great arteries (SLL), complicated by annuloaortic ectasia (AAE) and aortic regurgitation (AR). The patient, a 52-year-old male, complained mainly of dyspnea on physical exertion. In 1983, he underwent implantation of a pacemaker to treat advanced atrioventricular block. In 1994, his cardiac function deteriorated to NYHA III. Cardiac catheter examinations exhibited 2nd degree Seller's aortic valve insufficiency and 2nd degree insufficient closure of the left atrioventricular valve. The patient was Cardell classification B3, with a Shaher Type 4 coronary artery. A composite graft was made using a 27mm St. Jude Medical valve and a 30mm woven Dacron graft. The left atrioventricular valve had three leaflets, accessible from the right atrium using the septal approach. Kay's method was used to suture the posterior leaflet and reduce regurgitation. The patient has made favorable progress during the two-year follow-up period.

Cystic adventitial disease (CAD), a rare arterial disorder, can cause localized arterial stenosis or obstruction. A 55-year-old man presented with a 2-month history of left lower leg pain and paleness when bending the left knee. The patient was diagnosed with CAD of the left popliteal artery based on imaging examinations. Surgery was performed with the patient placed in the prone position using an S-shaped skin incision, and the left popliteal artery was exposed. A simple incision of the cyst wall was made. There was no sign of recurrence at 1 year postoperatively.

Lateral ankle sprain (LAS) is one of the most common sport-related injuries among basketball players. Most basketball players experience a first LAS particularly in junior high school. Thus, it is crucial to develop effective prevention strategies for LAS in junior high school populations. However, the characteristics for first-time LAS are not clear. This study aimed to compare the physical and functional characteristics of junior high school basketball players with and without a history of LAS. Two hundred and thirty-eight junior high school basketball players (128 boys and 110 girls) volunteered for this study. We asked participants to complete a self-reported injury history questionnaire. We also assessed physical functions, including range of motion, muscular strength, dynamic balance, and performance. The prevalence of LAS was 75.6% (boys: 73.4%, girls: 78.2%). Boys with a history of LAS had significantly higher height, body mass, and BMI compared to those without a history of LAS (p<0.05). Girls with a history of LAS had significantly lower scores on the star excursion balance test in the anterior reaching direction compared with the control group (p=0.015). Various measures of physical function were associated with LAS, but these associations were different between boys’ and girls’ basketball players. These findings from this study indicate that clinicians should identify sex-specific impairments associated with LAS when designing targeted intervention programs.
