Mid-term outcomes between different typing uncomplicated acute type B aortic dissection treated with thoracic endovascular aortic repair in a single center / 中华普通外科杂志

Objective:To investigate the imaging characteristics of uncomplicated acute type B aortic dissection (uATBAD) and the short-term and mid-term outcomes treated with thoracic endovascular aortic repair (TEVAR).Methods:One hundred and forty uATBAD patients treated by TEVAR at Zhejiang Provincial People's Hospital from Jan 2015 to Aug 2021 were retrospectively analyzed. Patients were divided into non-high-risk characteristics group (uATBAD group, 22 cases) and high-risk characteristics group (high-risk uATBAD group, 118 cases) according to the presence or absence of high-risk characteristics. The clinical and follow-up data were analyzed, and the incidence of complications, re-intervention rate, and mortality in the perioperative period and 5-year follow-up were evaluated.Results:The aortic diameter, false lumen diameter and the proportion of laceration in lesser curvature in the high-risk group were higher than those in the non-high-risk group ( P<0.05). There was no significant difference in the incidence of perioperative complications and 30 day mortality between two groups ( P>0.05). The follow-up time ranged from 6 to 83 months (mean 38.3 months). The 5-year mid-term follow-up showed that there was no significant difference in the incidence of aorta-related complications, re-intervention rate, and mortality between two groups ( P>0.05). Conclusions:The imaging characteristics of different typing uATBAD were significantly different. The short- and mid-term clinical effects of TEVAR were similar between the two groups.

Surgical approaches and related microsurgical anatomy about suprameatal approach: new surgical approach for cochlear implantation / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study a new surgical approach for cochlear implantation.@*METHOD@#We operated on 8 cadaver heads (16 side) use Suprameatal approach for cochlear implantation, describe related anatomic mark.@*RESULT@#The electrode is passed through the suprameatal tunnel, the EAC groove, the space underneath the chorda tympani between the malleal and the long process of the incus, and the cochleostomy. Angle between tunnel and temporal imaginary line is 28.0 degrees +/- 1.3 degrees in adult, 29.0 degrees +/- 1.7 degrees in children, the location of inserting electrode into cochleostomy is (1.31 +/- 0.13) mm to round window in adult, (1.19 +/- 0.12) mm in child.@*CONCLUSION@#The SMA approach is a safe technique, maintaining a safe distance to facial nerve and chorda tympani. So We should make right decision in clinic.
