Objective: To identify the optimal rotation time and pitch of 64-slice spiral CT angiography for arterial occlusive diseases (AOD) of the lower limbs. Methods: We performed test-bolus in eighty patients with AOD of the lower limbs (48 with intermittent claudication and 32 with ischemic rest pain or ulceration) to confirm the aortic peak time, popliteal artery peak time and aortopopliteal bolus transit time. The patients were randomly assigned to receive two sets of scan protocols for lower limb arterial 64-slice spiral CT angiography (CTA) examination (n = 40), protocol A, with a gantry rotation time of 330 ms and a pitch of 1.0; protocol B, with a gantry rotation time of 500 ms and a pitch of 0. 85. Two experienced radiologists independently evaluated the image quality of the lower limb artery. Results: Great differences in the time to peak enhancement in the aorta (14-33 s) and popliteal arteries (20-48 s) and the aortopopliteal bolus transit time (4-24 s) were found between different AOD patients. Wide overlap of the time to peak enhancement and transit time was observed between intermittent claudication patients and ischemic rest pain or ulceration patients. The qualities of segment images were rated as excellent 63.3% (152/240), good 30.0% (72/240), and poor 30.0% (72/240) for protocol A, and excellent 98. 3% (234/238) and good 1. 7% (4/238) for protocol B, with no poor images in protocol B. Conclusion: 64-slice CTA with a gantry rotation time of 500 ms, a pitch of 0. 85, scan time>30 s, and with the contrast agent injection time maintained at 35 s, can obtain better image of lower limb arteries in patients with AOD of the lower limbs.

Objective To evaluate the utility of three-dimensional digital subtraction angiography(3D-DSA) in the diagnosis of cerebral vascular diseases.Methods Seventy-one patients suspected and diagnosed with cerebral vascular diseases underwent conventional DSA and 3D-DSA. Three-dimensional (3-D) reconstructed images were obtained at a separate advantage 4.0 workstation after the rotational images were transferred. The available visualization techniques included maximum intensity projection (MIP), shaded surface display (SSD), and virtual angioscopy (VA). Results Sixty-four aneurysms were found in 44 cases. Nineteen cases were diagnosed as cerebral arteriovenous malformation (AVM) and 8 cases of cerebral ischemia were due to cerebral vascular stenosis (internal carotid artery in 6 cases and occlusion of anterior cerebral artery in 2 cases).Conclusions 3D-DSA is reliable, fast and safe for diagnosis of cerebral vascular diseases, especially involving intracanal areurysms AVM and vascular stenosis.

OBJECTIVETo study clinical results of the manual reduction in treatment.

METHODSFrom October 2010 to April 2013,39 children with Monteggia fracture associated with anterior interosseous nerve injury were treated by manual reduction and fixation on buckling rotation backward,including 17 females and 22 males with an average age of 6.3 years old ranging from 3.2 to 11 years old. Among them, 15 cases were on the right side and 24 cases on the left. The course of disease was 40 minutes to 8 days (averaged 1.5 days). There were 7 cases with skateboard injured, 13 cases with stumble injured, 11 cases with falling injured,8 cases with air bed injured. According to Bado classification, 13 cases were type II, 22 cases were type III, 4 cases were type IV.

RESULTSThe distal forefinger showed exercise normally in 34 cases at 3 weeks after treatment, and the patients restored normal activities at 6 weeks after treatment. All patients were follow-up from 54 days to 6 months (averaged 67 days. According to Mayo elbow functional evaluation standard,the scoring result was 19.62±1.35 in activity, 45.00 ± 0.00 in pain, 9.87 ± 0.80 in stability, 25.00±0.00 in strength, 99.49 ±1.92 in total. The outcome of all patients was excellent and good evaluation results.

CONCLUSIONIf the anterior interosseous nerve injury could be identified early and treated timely, patients could gradually restore reasonable function and recover with satisfactory results. Raising understanding of anterior interosseous nerve injury can effectively reduce misdiagnosis.

Objective To evaluate the clinical effectiveness of the combined use of S1 pedicle screws and the iliac screws in treatment of sacroiliac dislocation and fracture. Methods 11 patients with sacroiliac dislocation and fracture were treated with S1 pedicle screw and iliac screw fixation technique. In this group, the dislocation was associated with vertical displacement of the sacroiliac joint and rotational deformity of the pelvic ring. They were classified as type B or type C pelvic disruption according to the Tile's classification. 7 patients with disruption of the symphysis pubis or pubic branch fracture underwent additional fixation of the pelvic ring using a reconstruction plate. The remaining 4 patients were treated by the posterior procedure alone. Results The vertical displacement was completely reduced in 7 patients, and the rotational deformity completely corrected in 4 patients. The reduction was maintained at the time of final follow up evaluation. No perioperative complications were found. The combined use of S1 pedicle screws and the iliac screws provided immediate stability and sufficient reduction for sacroiliac dislocation in the 11 patients in this study. Conclusion This hybrid internal fixation procedure is useful for reduction and fixation of sacroiliac dislocation associated with the vertical and rotational instability of the pelvic ring.
