STUDY DESIGN: Retrospective case series. PURPOSE: To calculate the prevalence of L5-S1 intervertebral disc degeneration (IDD) by evaluating gynecological disease findings, obtained by pelvic magnetic resonance imaging (MRI), and reveal the risk factors for IDD by analyzing its relationship with age, sacral structure, body mass index (BMI), number of deliveries, and intrapelvic space-occupying lesions. OVERVIEW OF LITERATURE: Age, obesity, height, smoking history, occupation, and lumbosacral structure are reportedly the main factors of lumbar IDD. However, in women, the relationship of IDD with obstetric and gynecological history is unclear. METHODS: The presence of L5-S1 IDD was evaluated on sagittal T2-weighted pelvic MRI during gynecological evaluations in 660 Japanese women. We measured the sacral table angle (STA), sacral kyphosis angle (SKA), and intrapelvic space-occupying lesion size. Age, height, weight, BMI, number of deliveries, lumbosacral structure, size of space-occupying lesions, and presence of uterine leiomyoma based on medical records were compared between the IDD-positive and IDD-negative groups. RESULTS: Lumbosacral IDD was observed in 405 cases (61.4%), and its prevalence increased with age. Differences in age, height, weight, BMI, and number of deliveries between the IDD-positive and -negative groups were significant, but differences in STA, SKA, and presence of uterine leiomyoma and space-occupying lesion size were not. Logistic regression analysis indicated that age, BMI, and STA were risk factors for lumbosacral IDD. CONCLUSIONS: Age is the biggest risk factor for lumbosacral IDD in Japanese women, with BMI and STA also contributing to its development. However, SKA and obstetric and gynecological history were not significantly involved.

A 61-year-old woman had extracardiac unruptured aneurysms of the right and noncoronary sinuses of Valsalva, detected incidentally on electrocardiogram taken for a physical checkup. Two-dimensional echocardiography revealed that the sizes of the aneurysm of the right and noncoronary sinuses were 41×40 and 38×28mm respectively, but the shape of left coronary sinus was almost normal. The aortic valve leaflet was normal and the diameter of the aortic annulus and sinotubular junction was 23 and 27mm respectively. The Doppler color-flow echocardiogram showed moderate aortic regurgitation which resulted in prolapse of the right aortic cusp due to deformity of the annulus. We performed modified aortic root remodeling using a tailored Dacron graft to preserve the native aortic valve. Right and noncoronary sinuses of Valsalva were all excised with a small button of the aortic wall around the ostia of the right coronary artery. The left coronary sinus was left as it was. Then each commissure received sub-commissural annuloplasty and was pulled up. The defect of Valsalva was reconstructed with a 26mm Dacron tube graft, the proximal end of which was tailored to a scallop shape and that correspond to left coronary sinus was excised. The right coronary artery was reimplanted utilizing the Carrel patch method. Although we needed additional CABG to the right coronary artery and IABP support due to vasospasm of the right coronary artery, the postoperative course was uneventful. Echocardiography of the aortic valve before discharge showed a normal function without regurgitation.
