ABSTRACT
Objective: To investigate the diagnostic value of 64 multislice spiral CT (64-MSCT) and 1.5T MRI in nurseling with congenital vascular rings. Methods:We retrospectively studied the diagnostic records of 64-MSCT and 1.5T MRI in 48 nurseling with congenital vascular rings. There were 42 cases received CTA, 12 received MRA and 6 received both CTA and MRA. We classiifed the types of vascular rings by Edwards sketch map of aortic arch embryonic development and trachea wrapping conditions. The diagnostic values of 64-MSCT and 1.5T MRI on vascular rings were compared. Results: There were 25 patients with complete vascular rings including 3 of double aortic arch, 12 right aortic arch with left subclavian artery and patent ductus arteriosus (PDA), 9 combining with arterial ligament, 1 neck right aortic arch with left subclavian artery combining left PDA;and 23 patients with in-complete vascular rings including 2 pulmonary artery sling, 9 left aortic arch with right subclavian artery combining left PDA, 10 combining with arterial ligament, 1 right aortic arch with left subclavian artery combining right PDA, 1 with innominate artery compressed trachea. There were 32/48 patients combined with cardiac malformations, both 64-MSCT and 1.5T MRI may well reveal the composition and special relationship of vessel rings. The minimum intensity projection (MinIP) and air volume rendering (VR) of 64-MSCT may clearly display the morphology and development of trachea, image fusion technique could directly show the special relationships among vascular rings, trachea and esophagus. While 1.5T MRI was relatively poor to present tracheal image. Conclusion: 64-MSCT could accurately and comprehensively display the special relationships among the vessels rings, trachea and esophagus;which was the best method for diagnosing the nurseling with vessel rings in clinical practice.
ABSTRACT
Objective To investigate the value of lower limbs fixation methods for the treatment of intussusception in children with air enema with.Methods 2 1 1 pediatric patients with intussusception who had accepted the treatment of air enema with two dif-ferent fixation methods on lower limbs were enrolled.Comparisons of median treatment duration and therapeutic effect between the two methods were investigated.Results In 32 patients with knee-joint fixation method,27 were successful with median treatment duration 4.84 minutes.Meanwhile in other 179 ones with lower limbs fixation method,152 were successful with median duration 7.96 minutes.And the duration difference between two methods was found (P<0.05).Conclusion Knee-joint fixation may help significantly shorten the median treatment duration for the treatment of intussusception with air enema in children.
ABSTRACT
@#Objective To investigate the effects of rehabilitation intervening in different stage on activities of daily living of old stroke patients. Methods 74 old cases were divided into 3 group according to the time from onset of stroke to rehabilitation intervention: group A (＜3 months), group B (3～6 months), and group C (>6 months). They were treated with routine rehabilitation for 2 months and assessed with Barthel Index before and after rehabilitation. Results All the patients improved their ADL significantly after rehabilitation (P=0.000), and those in group A improved more than in group C (P<0.05). There was no significant difference between group A and B, and group B and C (P>0.05). Conclusion The rehabilitation can effectively improve the ADL of old stroke patients. The early the rehabilitation intervenes, the better the ADL is.
