Spinal cord injury after stented elephant trunk deployment might be related to occlusion of the excessive intercostal arteries or thromboembolism. Patients with a history of abdominal aortic aneurysm repair who require extensive deployment of the stented elephant trunk seem to be at a higher risk for spinal cord injury.
U The occurrence of disc herniation is rare in children. A 27-month-old child fell from his cradle and developed, in the following 2 weeks, irritability, low-back pain, and difficulty in walking. On physical examination a compensatory gait, paravertebral muscle spasm, and a restricted right straight-leg raising test were demonstrated. Plain x-ray films revealed a narrowed L4–5 intervertebral space. Magnetic resonance imaging of the lumbosacral spine demonstrated decreased signal in the L4–5 disc, with posterior disc protrusion. At surgery, blood infiltrating the subperiosteal plane was observed. Via a left hemilaminectomy and under microscopic magnification, the left L-5 nerve root was found to be intact, and on the right side significant nerve root compression was identified. During dissection an accidental dural tear occurred. A right L-4 hemilaminectomy was performed, and the disc fragments were removed until a complete nerve root decompression was obtained and the dura was repaired. The child recovered uneventfully and was asymptomatic 7 years postsurgery. This child is one of the youngest patients with a herniated disc reported in the world literature. The authors discuss the diagnostic difficulties and management of this entity in children.
Retroaortic left renal vein occurs infrequently and poses potential hazards to the surgeon during abdominal aortic surgery. We herein report the case of a 77-year-old man with a retroaortic left renal vein who underwent an abdominal aortic aneurysm (AAA) repair. The retroaortic left renal vein was diagnosed preoperatively by contrast-enhanced computed tomography (CT). The patient underwent a successful abdominal aortic replacement with an uneventful postoperative course without any renal complications. The CT scan was useful for both evaluating the AAA and for establishing the presence of the venous anomaly. Major venous anomalies (retroaortic left renal vein, left renal vein collar, left-sided inferior vena cava, and caval duplication) should thus be taken into consideration in AAA operations.
Two thirds of Mexican patients with DM2 attending primary health care medical units had nephropathy, 40% of whom were at an early stage of the disease. Many modifiable and nonmodifiable risk factors were present in these patients, but the most significant predictors for nephropathy are older age, longer duration of diabetes, and the presence of retinopathy, hypertension, and cardiovascular disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
