OBJECTIVETo provide insight on psychosocial factors underlying utilization of health services of women whom perceived reproductive tract infection (RTI) symptoms.

METHODSA cross-sectional study, adopted Aday and Andersen's Social Behaviour Model was conducted in 1998 - 1999 in China. Hebei province and Beijing were purposely chosen as the research sites. All eligible married women aged 21 to 60, 864 subjects, were interviewed in person.

RESULTSFindings showed that the percentage of self-reported symptoms of RTIs was 35.6 in urban compared to 46.8 in the rural areas. The proportion of women with RTIs who utilized health services was 27.5 versus 26.7 percent among the two groups. Urban women, mostly 'white collar' class, with free medical service, satisfied with health providers, receiving information from health provider and having severe current experience RTIs, were more likely to use health services. Rural women, however, having both severe prior experience and current experience of RTIs, high family income, having much knowledge about self-medication, perceiving less social stigma of getting RTIs, and perceiving severity of RTIs, were more likely to use health services.

CONCLUSIONThese findings showed that there was a great need on providing culturally acceptable reproductive health education at different places so as to improve women's ability of self-care. Regular medical check-up for women is also important for improving the quality of health service. Reform on health insurance seemed necessary. Factors as social stigma related to RTIs, giving women social and moral support also need to be taken into account.

OBJECTIVETo provide insight into the psychosocial factors underlying the utilisation of health services by women with reproductive tract infection (RTI) symptoms.

METHODSA cross-sectional study, adopting Aday and Andersen' s Social Behaviour Model, was conducted between 1998 and 1999 in Chinese Hebei province and Beijing. A total of 864 eligible married women (age 21 to 60 years) were face to face interviewed.

RESULTSThe percentage of self-reported symptoms of RTIs in urban and rural women was 35.6 and 46.8, respectively; the proportion of women with RTIs who utilised health services was 27.5% and 26.7%, respectively. Compared to urban women, rural women had less knowledge on RTIs and more traditional beliefs, and were more satisfied with local health services. The results of logistic regression analysis showed that the common factor influencing health service utilisation in women with RTIs was current experience of RTIs. Knowledge about self-medication, perceived social stigma attached to RTIs, prior experience of RTIs, family income and perceived severity of RTIs were also predictors of utilisation of health services in rural women with RTIs. Satisfaction with health providers, information received from health providers, prior experience of RTIs, occupation and medical care coverage were predictors of utilisation of health services in urban women with RTIs.

CONCLUSIONThe prevalence of RTIs is high, but the rate of seeking health services is low. There is a great need for emphasizing culturally acceptable reproductive health education in different places to improve women' s ability for self-care. Regular medical check-ups for women are also important. It is necessary to improve the quality of health service, complete the reform of health insurance and alleviate women' s social stigma related to RTIs, giving women social and moral support.

Methods:From February 2018 to January 2022, the clinical data of 1 123 patients who underwent Starclose vascular closure device, Angio-Seal and Exoseal vascular occlusion devices and Perclose ProGlide vascular suture device at femoral artery puncture hemostasis after neuro-intervention, in the Department of Interventional Radiology (Eastern District), The First Affiliated Hospital of Zhengzhou University, were retrospectively analyzed. The patients were divided into three groups based on the intervention method: the closure group (Starclose, n=271), the occlusion group (Angio-Seal, n=327 and Exoseal, n=352) and the suture group (ProGlide, n=173). Next, the hemostatic efficacy and complications associated with the three devices were analyzed and compared. Additionally, regression analysis was conducted to identify any relevant factors that may contribute to complications. Results:Three vascular hemostatic devices demonstrated effective hemostasis and the success rate were 92.6% in the closure group (Starclose), 93.4% in the occlusion group (Angio-Seal 93.0% and Exoseal 93.8%) and 89.6% in the suture group (ProGlide). There was no statistically significant difference( χ2=3.026, P=0.388). Single or multiple complications were observed in 102 patients (9.1%), including local oozing (16 cases in the closure group, 39 cases in the occlusion group, 13 cases in the suture group), local hematoma (14 cases in the closure group, 31 cases in the occlusion group, 11 cases in the suture group), pseudoaneurysm (13 cases in the closure group, 35 cases in the occlusion group, 10 cases in the suture group), local infection (2 cases in the closure group, 3 cases in the occlusion group, 1 case in the suture group). There were no statistically significant differences ( P>0.05). Moreover, serious complications such as femoral artery occlusion, embolus shedding and permanent nerve injury weren′t observed in the three groups. Multivariate logistic regression analysis revealed that overweight ( OR=1.562,95% CI 1.023—2.385, P=0.039), femoral artery with calcified plaque ( OR=1.934,95% CI 1.172-3.189, P=0.010), combined use of multiple antiplatelet drugs ( OR=1.769,95% CI 1.103—2.839, P=0.018), use of an 8F sheath( OR=2.824,95% CI 1.406—5.671, P=0.004) and the operator′s proficiency ( OR=0.508,95% CI 0.328—0.788, P=0.002) were the independent factors influencing complications, of which the first four were identified as risk-promoting factors for complications while the operator′s rich experience and high proficiency were the protective factors. Conclusions:Three hemostatic devices demonstrate effective hemostasis and comparable rates of complications at femoral artery puncture hemostasis after neuro-intervention. Overweight, femoral artery with calcified plaque, combined use of multiple antiplatelet drugs, use of an 8 F sheath and the operator′s proficiency were independent factors influencing complications.Ojective:To investigate the efficacy and complications associated with vascular suture, closure and occlusion devices at femoral artery puncture hemostasis after neuro-intervention.

Objective:To establish the common carotid artery aneurysm models of Wallstent double stent overlapping implantation in miniature pigs, and evaluate the safety and effectiveness of this procedure by observing the imaging and pathological changes.Methods:Sidewall aneurysm and fusiform aneurysm models in Bama miniature pigs were established surgically and 2 Wallstent stents were overlapped and implanted in situ. Aneurysm healing immediately after surgery and during 8 weeks of follow-up were evaluated according to 2D-DSA by O'Kelly-Marotta (OKM) grading scale and Kamran scale; degrees of stent adhesion immediately after surgery and status of stent endothelialization and aneurysm healing at 2, 4, and 8 weeks after surgery were observed by high resolution C-arm CT(HR-CBCT) and optical coherence tomography (OCT); and the changes of stent endothelialization were evaluated by comparing the HR-CBCT and OCT results with histopathology at 8 weeks after surgery. Perioperative adverse events were recorded.Results:After successful establishment of common carotid artery aneurysm models (including 4 sidewall aneurysms and 4 fusiform aneurysms with average diameter of [11.0±2.8] mm) in 8 miniature pigs, a total of 16 Wallstent stents (2 in each aneurysm) were implanted across the aneurysmal neck, with a technical success rate of 100%. No serious complications such as acute stent thrombosis, or aneurysm rupture and bleeding were observed in the perioperative period. The 2D-DSA immediately after surgery showed obvious intracranial contrast agent retention in 6 patients (1 patient in grading 1, 3 in grading 2, and 2 in grading 3) and aneurysm occlusion in 2 patients (grading 4). Eight weeks after follow-up, all 8 aneurysms had complete occlusions (grading 4); and 2 experimental pigs had in-stent restenosis, with stenosis rates of 52% and 67%, respectively. HR-CBCT and OCT immediately after surgery and during follow-up indicated that the stent metal braid was gradually covered by proliferating intima, with disappeared aneurysm. The cause of in-stent restenosis in 2 experimental pigs was local intima hyperplasia resulted from poor stent adhesion, and pathological findings indicated that the intima hyperplasia was mainly composed of smooth muscle cells and fibrous connective tissues.Conclusion:In animal models, Wallstent stent overlapping implantation is safe and effective in common carotid aneurysms, but intraoperative adverse adhesion of overlapping stent should be avoided.

Objective:To assess the efficacy and safety of overlapping braided carotid artery stent (Wallstent) implantation in large extracranial internal carotid artery aneurysms (15 mm≤diameter<25 mm) and giant ones (diameter≥25 mm).Methods:A retrospective study was performed; the clinical data of 23 patients with large or giant extracranial internal carotid artery aneurysms accepted overlapping Wallstent stent implantation in Department of Interventional Radiology, First Affiliated Hospital of Zhengzhou University from August 2015 to June 2023 were collected. Immediately after implantation, DSA was used to evaluate the retention of contrast agent within the aneurysms and high-resolution C-arm CT (HR-CBCT) was used to detect the apposition between the two stents and between the stents and inner wall of the blood vessel. Perioperative complications were recorded. Clinical follow-up was performed bi-monthly via outpatient visits or telephone, and modified Rankin scale (mRS) was used to assess the prognoses (mRS scores of 0-2 as good prognosis) at the last follow-up; aneurysm occlusion was evaluated in a 6-month follow-up by DSA and in-stent restenosis in a final imaging follow-up by DSA or CTA according to the OKM grading. Results:Twenty-two patients had successful overlapping implantation of 2 Wallstent stents; blood flow was restricted in one patient due to carotid artery dissection at the distal end of the aneurysm during stent implantation and restored after a Neuroform EZ stent and 2 Wallstent stent implantation from the distal-proximal lesion; technical success rate of 95.7% (22/23) was obtained. DSA immediately after implantation showed obvious contrast medium retention in all aneurysms. HR-CBCT indicated good stent apposition in 21 patients and mild incomplete stent apposition in 2. Clinical follow-up was finished in 23 patients, ranged 6-31 months (mean 11.5±6.3 months); all patients had good prognosis at the last follow-up. Imaging follow-up, including at least once DSA, was conducted for all patients, with intervals ranging from 6 to 15 months (mean 10.4±3.4 months); DSA 6 months after implantation showed complete aneurysm occlusion in 19 patients (OKM grading D) and a bit of residual contrast in 4 patients (OKM grading C); final imaging follow-up (DSA in 2 and CTA in 21) revealed in-stent stenosis in 2 patients (stenosis rates of 51% and 87%) with obvious improved stenosis after balloon angioplasty and patent stents in 21 patients without evidence of aneurysm opacification.Conclusion:Overlapping braided carotid artery stent (Wallstent) implantation is an effective and safe approach for managing large or giant extracranial carotid artery aneurysms.
