ABSTRACT
Objective To compare the effect of left transradial approach(TRA)with right TRA in performing transcatheter arterial chemoembolization(TACE)for the treatment of hepatocellular carcinoma(HCC).Methods The clinical data of a total of 174 HCC patients,who received conventional TACE via radial access at Henan Provincial Hospital of Traditional Chinese Medicine of China between June 2021 and May 2022,were retrospectively analyzed.Among the 174 patients,104 patients were ≤65 years old,of whom 52 received TACE by using left TRA and 54 received TACE by using right TRA;68 patients were＞65 years old,of whom 32 received TACE by using left TRA and 36 received TACE by using right TRA.The complications,fluoroscopy time spent for catheterization into celiac trunk,surgical total fluoroscopy time and radiation dose were compared between the left TRA group and right TRA group.Results In the patients ≤ 65 years old,there were no statistically significant differences in the fluoroscopy time spent for catheterization into celiac trunk,the surgical total fluoroscopy time,the radiation dose and the incidence of complications between the left TRA group and the right TRA group.In the patients＞65 years old,no statistically significant difference in the incidence of complications existed between the left TRA group and the right TRA group(P＞0.05),while the fluoroscopy time spent for catheterization into celiac trunk((60.3±28.3)s vs(86.3±45.2)s,P=0.003),the surgical total fluoroscopy time((11.2±4.5)min vs(14.3±6.3)min,P=0.030)and the radiation dose((452.2±121.7)mGy vs(563.8±181.5)mGy,P=0.022)in the left TRA group were remarkably lower than those in the right TRA group,the differences were statistically significant.Conclusion In conventional TACE,there is no obvious difference in the incidence of puncture point-related complications between using left TRA and using right TRA;but in the patients ≤ 65 years old,the use of left TRA can significantly reduce the surgical total fluoroscopy time and radiation dose.(J Intervent Radiol,2023,32:1226-1229)
ABSTRACT
Objective To analyze the complications and clinical effects of interventional embolization and surgical clipping for the treatment of posterior communicating artery aneurysms, and to compare the results between the two methods.Methods A total of 90 patients with confirmed posterior communicating artery aneurysm, who were admitted to the Second Affiliated Hospital of Zhengzhou University during the period from August 2013 to March 2015, were enrolled in this study. Of the 90 patients, 49 received interventional embolization therapy (interventional embolization group) and 41 underwent surgical clipping treatment (surgical clipping group). Before the treatment the patient's condition was evaluated according to Hunt-Hess classification, after the treatment the therapeutic effect was assessed with Glasgow prognosis scale (GOS). The postoperative GOS scores and complications in patients with different Hunt-Hess classification were compared between the two groups. Results In patients of Hunt-Hess 0-Ⅲ grade, no statistically significant differences in postoperative GOS scores existed between the interventional embolization group and the surgical clipping group (t=0.842,P>0.05), while the postoperative GOS scores in patients of Hunt-HessⅣgrade of the interventional embolization group was remarkably higher than that in patients of Hunt-HessⅣgrade of the surgical clipping group, the difference was statistically significant (t=1.713,P<0.05). The incidence of complications in the interventional embolization group was significantly lower than that in the surgical clipping group (x2=1.036,P<0.05). Conclusion For the treatment of Hunt-Hess 0-Ⅲgrade posterior communicating artery aneurysms, the interventional embolization and the surgical clipping show no difference in their therapeutic effects; while for the treatment of Hunt-Hess Ⅳ grade posterior communicating artery aneurysms, the interventional embolization in superior to the surgical clipping, as the interventional embolization carries lower operation risk and complication incidence, and it also has reliable effect.

ABSTRACT
Objective To study the imaging features and the reason of misdiagnosis of multi-nodular bronchioalveolar carcinoma(BAC).Methods 33 cases with the BAC proved by pathology,were reviewed,including 20 males and 13 females,the age ranged from 34～76 years with an average age of 54.2 years.X-ray there were over twice X-ray filmes in all cases,and CT scans with GE 9800 Quick were performed in 30 cases . The imaging features were analysed . Results Imaging findings : Miliary noduli were inhomogeneous in distribution,size and density.The large noduli generally located at the periphery of lung or under the pleura and noduli were focused together,“vacuole sign” was present in 72.7% cases and the noduli were around the vacuole,and lobulated.69.7% of nodule focuses were in company with consolidatory shade . The rate of X-ray misdiagnosis was 75.8%, in which 72.0% were misdiagnosed as TB . CT misdiagnostic rate was 36.4%.The misdiagnostic reasons were unsufficient in consideration of clinical symptom and imaging findings.Conclusion The BAC is the developmental stage of cancer.The accurate diagnosis can be improved if clinical-imaging features are analysed properly,and reexamination and comparison are taken carefully.
