Objective To explore the spiral computed tomography (CT) imaging feature of post-intubation tracheal stenosis (PITS) and to discuss its clinical significance. Methods The clinical data and CT imaging findings of 27 patients with PITS were retrospectively analyzed. The location, degree and shape of PITS were analyzed, and the imaging features were summarized. Based on the imaging features the etiology of PITS was suggested, and the role of imaging feature in assessing PITS condition and in planning clinical management was evaluated. Results A total of 35 tracheal strictures were detected in the 27 patients. The location of the strictures included trachea incision site (n=10), balloon level (n=5) and distal end of tube (n = 20). In all patients the degree of stenosis was > 30%. Localized stenosis was seen in 15 cases, which presented as “hourglass”or “girdle”shape. Segmental stenosis was found in 4 cases, which was characterized by a “ribbon” or “dumbbell” stricture on CT scans. Complex stenosis was found in 8 cases. With the help of imaging findings, all patients got timely, proper and individualized treatment. Conclusion PITS has typical imaging characteristics. Spiral CT scanning should be regarded as the imaging examination of first choice. Based on the different imaging characteristics, the relevant departments can evaluate patient’s condition and make individualized treatment plan. The imaging finding is very helpful for anesthesiologists and other clinicians in recognizing and in managing the post-intubation tracheal stenosis.

Objective To discuss the ventilatory catheter-assisted airway stenting under local anesthesia for airway stenosis.Methods From May 2008 to January 2013,25 consecutive patients with airway stenosis underwent the treatment of ventilatory catheter-assisted airway stenting under local anesthesia.The dyspnea score was grade Ⅱ in 3 patients,grade Ⅲ in 18 patients and grade Ⅳ in 4 patients.During the treatment,a 4 F VER catheter was placed into one of the main bronchi as a ventilatory catheter for oxygen supply in advance,the oxygen flow was set at 2 to 4 L/rmin according to the patients' condition,then the airway stenting was performed,after release of the stent,the ventilatory catheter was removed smoothly.Data on technical success,clinical outcome and follow-up were collected and analyzed respectively.The paired t test was performed to compare variables before and after tracheal stenting.Results Ventilatory catheter-assisted airway stenting under local anesthesia was technically successful in all patients.A total of 25 stents were placed in 25 patients.The stents included I-shaped stents (n=19) and Y-shaped stents (n=6).After the oxygen supply,the patients' SaO2 was increased to 94％ to 97％ rapidly.When the stent introducer sheaths were passing through the stenotic site,the SaO2 could be maintained at 92％ to 97％.The improvement of the respiratory difficulty was achieved in 100％ of our patients.The hypoxia symptom was relieved immediately after stents placement,the dyspnea score decreased to grade 0 in 2 patients,to grade Ⅰ in 19 patients and to grade Ⅱ in 4 patients.Respiratory rate and SaO2 improved from (30.0±2.1) times/min and (6.0±3.8)％ before stenting to (19.7±1.6) times/min (t=23.33,P＜0.01) and (93.0± 1.7)％ (t=23.50,P＜0.01) after stenting,respectively.Through the follow-up,3 patients suffered the stent-related complications after discharge,the complications included re-stenosis (n=2) and fracture(n=1).Conclusion Ventilatory catheter-assisted airway stenting under local anesthesia can be an effective,simple and safe method for airway stenosis.

Objective To evaluate the therapeutic results of comprehensive interventional therapy for antiphospholipid syndrome (APS) complicated by deep vein thrombosis (DVT). Methods A total of 10 patients with APS complicated by DVT, who were encountered at authors’ hospital during the period from January 2001 to October 2013, were enrolled in this study. The patients included 3 males and 7 females with a mean age of 45 years (39-74 years). The patients were divided into pure anticoagulantion therapy (group A, n = 4) and catheter-based thrombolysis via the jugular vein combined with anticoagulantion therapy (group B, n = 6). The clinical data were retrospectively analyzed. After the treatment warfarin was orally administered in all patients for at least one year. Results There were no significant differences in general clinical characteristics between the two groups. Before the treatment, the circumference difference of the thighs was (5.55 ± 0.51) cm in group A and was (5.13 ± 0.45) cm in group B. After the treatment, the circumference difference of the thighs was (1.85 ± 0.31) cm in group A and was (0.95 ± 0.26) cm in group B. In both groups, the postoperative calf size was significantly reduced when compared with the preoperative one (both P < 0.01), which was more obvious in group B than in group A (P < 0.05). The detumescence rate in group B was significantly higher than that in group A, which was (81.7 ± 4.1)% vs (67.3 ± 3.6)%(P <0.01). The average hospitalization days of group B and group A were (13.83 ± 0.75) days and (20.75 ± 2.63) days respectively, and the difference was statistically significant (P < 0.05). In group A, clinical effective result was obtained in three patients and ineffective result in one patient, while in group B clinical cure was obtained in all patients. Conclusion In treating APS complicated by DVT, catheter-based thrombolysis via the jugular vein combined with anticoagulantion therapy is safe, effective and time-saving, while pure anticoagulation therapy has only limited efficacy.
