The outcome of lung transplantation for end-stage pulmonary diseases with pulmonary hypertension: a single-center experience.

Background: Lung transplantation is a treatment for end-stage lung disease. The optimal transplant strategy for patients with end-stage lung disease complicated by pulmonary hypertension (PH) is controversial. The aim of this study is to review this experience and analyze the outcomes of lung transplantation for PH. Methods: This retrospective study collected data on patients with PH undergoing lung transplantation between March 2016 and December 2019 at a single center in China. The perioperative features and short- and medium-term outcomes between single-lung transplantation (SLT) and double-lung transplantation (DLT) were compared. Kaplan-Meier methods were used to analyze overall survival across a variety of transplantation procedures, age, mean pulmonary artery pressure (mPAP), body mass index (BMI), and indications of transplantation. Results: A total of 63 patients with PH were finally included in the analysis. The mean age, mean BMI, and mPAP were 56.37 years, 19.56 kg/m2, and 35.4 mmHg respectively. The overall 1-, 2-, and 3-year survival was 70%, 63%, and 60%, respectively. Five (7.94%) patients died within 30 days after surgery and nine patients (14.3%) died from infection during the followed-up period. There were no significant differences in the short- and medium-term survival outcomes of SLT and DLT, but postoperative pulmonary function was better in DLT. Patients older than 60 years of age had worse survival (P=0.01). Conclusions: The short- and medium-term survival outcomes between SLT and DLT are similar in selected patients with PH. DLT provides better pulmonary function. Patients older than 60 years are associated with worse survival.

Solitaire stent placement for treatment of complex intracranial arterial stenosis: A preliminary result / 第二军医大学学报

Objective To evaluate the feasibility, safety and efficacy of Solitaire stent placement for treatment of complex intracranial atherosclerotic stenosis. Methods We retrospectively reviewed the clinical data of 18 patients who underwent Solitaire stent placement for symptomatic intracranial arterial stenoses in our department between November 2011 and June 2012, with focus on the stenosis morphology, condition of the diseased blood vessels, surgical success rate, and perioperative complications. We also summarized the early outcomes and imaging findings during follow-up. Results The patients included 8 males and 10 females, with a mean age of 66. 55 + 9. 84 years old. Mori typing results were 5 A, 8 B, and 5 C types; LMA typing results were good in 2, moderate tortuosity in 12, severe tortuosity in 4 cases. All the patients received successful Solitaire stent implantation. The average stenosis rate was reduced from (74 + 12. 5)% to (10 + 5. 5)% after the procedure. There was only one patient (5. 6%) had post-operative complication (cerebral infarction of the target vessel territory), who had temporal symptom and recovered well at follow-up. Clinical follow-up was available for 18 patients, with a mean of 6.2+ 1. 4 months; and no patients experienced any ischemic episodes. Fifteen patients had DSA or CTA follow-up for a mean of 7. 8 + 2. 6 months. There were 3 in-stent restenosis (20%) cases and one of them wassymptomatic with transient ischemic attack. Conclusion Solitaire stent placement is feasible, safe and effective for complex symptomatic intracranial artery stenosis, with definite short-term effectiveness, and the long-term effect warrants further investigation.
