ABSTRACT
Objective To discuss and evaluate the value of multi slice spiral CT angiography in the diagno -sis of penetrating atherosclerotic ulcer materials .Methods 17 patients of PAU were collected and examined with MSCT,the location,radiological diagnosis and complications of PAU on axial ,CTA and 2D/3D images were analyzed. Results Ulcer-like aortic projections were observed of 17 patients,and connected with aortic cavity ,where narrow neck sign was showed .The indirect signs included localized or extensive IMH ,calcification of aortic wall and dilata-tion of aorta .Conclusion Multi slice spiral CT angiography is an effective method for the diagnosis of PAU by provi -ding valuable information for the diagnosis and treatment .
ABSTRACT
Objective To investigate the clinical value of multi-slice spiral CTA ( MSCTA ) and image-post processing techniques in diagnosis of acute aortic syndrome ( AAS) .Methods 71 patients with AAS were scanned by TOSHIBA Aquilion 64-slice spiral CT,the images on axial and 2D/3D were analyzed.Results 71 cases included 48 cases of aortic dissection ( AD) ,10 cases of intramural hematoma ( IMH) and 13 cases of penetrating atheroscle-rotic ulcer ( PAU) .MSCT depicted the imaging features of AAS:AD showed intimal flap and true and false lumens;IMH showed crescent or circular thickening of aortic wall .PAU showed a niche filling with contrast medium and pro-truding the aortic lumen ,where narrow neck signwas shown .The location ,radiological diagnosis and complications of AAS were observed in 71 patients.Intervention treatment or surgical treatment was conducted in 27 cases after defi-nite diagnosis .Conclusion MSCT is a fast and noninvasive examination technique , and it can provide important information for the diagnosis and treatment of AAS .
ABSTRACT
Objective To explore the nursing problems and application value of intrauterine instruments positioning in assistance of tubal interventional treatment. Methods Uterine probe or expanding-uterus stick was used in 66 cases who had abortde with routine methods for rectifying the position of uterus or adhesion re-lease, then the selected catheter was inserted to the targeted fallopian tube for interventional aim. Nurses paid at-tention to the nursing cooperation and summarized the nursing points during the whole processes. Results With this technique, the achievement ratio of selected insertion to fallopian tube was 100% and that of recanaliza-tion was 92.68%. The major adverse effects were hypogastralgia and little vaginal bleeding. Pneumogastric nervereactions were found in 3.03% cases. Conchusions The assistant-immanent could elevate the achievement ra-tio of selected insertion to the targeted fallopian tubes, but the nursing problems shouldn't be neglected.
ABSTRACT
Many accessories to the ventilator such as the humidifier and the artificial nose are widely used and applied. In clinical medicine engineering, doctors and medical engineers have to be integrated to perform patient-centered care and to accomplish the functional structure based on the patient's essential physiological indexes. The scientific quality control has to be implemented during the operation, maintenance and sterilization of the equipment, thus iatrogenic infection can be avoided and medical diagnosis and treatment can be enhanced.
