Abstract:
Objective:To investigate the effects of survival status in Stanford type A aortic dissection (TAAD) patients over 70 years old by different treatment methods.Methods:The clinical data of 151 TAAD patients over 70 years old from January 2012 to January 2022 in the Affiliated Hospital of Jining Medical University were retrospectively analyzed. Among them, 60 patients were treated with surgery (surgical treatment group), and 91 patients with conservative method (conservative treatment group). The duration of hospitalization and complications (including pericardial effusion, acute myocardial infarction, pericardial tamponade, shock, stroke, mesenteric ischemia and acute renal failure) were recorded. The patients were followed up within 30 d after the onset of illness. The survival status was recorded. The multivariate Cox regression analysis was used to analyze the independent risk factors of death in TAAD patients over 70 years old.Results:The duration of hospitalization in surgical treatment group was significantly longer than that in conservative treatment group: 14.00 (7.00, 19.75) d vs. 5.00 (2.00, 10.00) d. The incidences of pericardial tamponade, shock and acute renal failure: 1.7% (1/60) vs. 13.2% (12/91), 8.3% (5/60) vs. 24.2% (22/91) and 0 vs. 9.9% (9/91), with statistical differences ( P<0.01 or <0.05), but no statistical differences in the incidences of pericardial effusion, acute myocardial infarction, stroke, mesenteric ischemia between two groups ( P>0.05). Patient follow-up for 30 d, the mortality rate in surgical treatment group was significantly lower than that in conservative treatment group: 15.0% (9/60) vs. 46.2% (42/91), with statistical difference ( χ2 = 15.69, P<0.01). The multivariate Cox regression analysis result showed that conservative treatment, female, increased aortic root diameter and concomitant stroke were the independent risk factors of death in TAAD patients over 70 years old ( RR = 2.311, 2.135, 1.051 and 3.737; 95% CI 1.056 to 5.057, 1.083 to 4.212, 1.004 to 1.100 and 1.393 to 10.026; P<0.05 or <0.01). Conclusions:The early surgical treatment is recommended in TAAD patients over 70 years old with surgical indications.
