XXXX survival and limb prognosis after arterial embolectomy.

@entity1 @entity715 @entity943 @entity66
Mortality and morbidity after arterial thromboembolectomy were studied in 202 @entity1 . Factors affecting reoperation and survival were identified according to Cox's proportional hazards model. 30-day mortality was 26% and amputation rate 18.5%. NYHA classification was the most important predictor for survival; class 3-4 had a 3.35 times higher death rate than class 1-2. An age greater than 75 years increased the death rate by 2.35 times and the presence of ischaemic heart or peripheral @entity66 increased it by 1.69 and 1.65 times, respectively. Symptoms less than or equal to 1 day in duration were associated with a death rate 1.53 times higher than for a longer duration. Reoperation rate was 2.15 times greater in the absence of @entity943 . The amputation rate was 3.79 times higher in NYHA class 3-4 than in class 1-2, and 2.47 times higher in the presence of peripheral @entity66 . Apparently, @entity715 rather than recurrent embolism is the most important cause of reoperation and amputation. The severity of pre-existing @entity66 largely determines prognosis regardless of the severity of the superimposed acute occlusion.
