[The value of electroneurography in recognition of peripheral ischaemic polyneuropathy in patients suffering from critical leg ischaemia]. / Wartosc badan EMG w rozpoznaniu polineuropatii niedokrwiennej u chorych z krytycznym niedokrwieniem konczyn dolnych.

Peripheral arteries disorders cause not only leg ischaemia, but also peripheral polyneuropathy. Polyneuropathy increases ischaemic pain. The aim of this study was to estimate how many patients suffering from critical leg ischaemia have symptoms of peripheral polyneuropathy. 40 patients were investigated: 37 men and 3 women; mean age was 57 years. All patients underwent electroneurographic examination. It consisted of measurements of motor conduction in tibial and peroneal nerves, wave F, sensory conduction in sural nerve. Polyneuropathy was observed in 95% of patients. The frequency of polyneuropathy was also significantly enlarged in leg with non critical ischaemia. We did not observe the greater risk of polyneuropathy in diabetic patients. The work is an introduction to the following clinical studies.

[Analysis of mortality risk factors in patients with ruptured abdominal aortic aneurysm]. / Analiza czynników ryzyka zgonu u chorych z peknietym tetniakiem aorty brzusznej.

The purpose of the study was to estimate which factors could have effect on successful outcome of surgery in patients operated on for ruptured abdominal aortic aneurysm (RAAA). The analysis referred to 66 patients operated upon from 1992 to 1995. The specification of all factors which could bring the influence on the successful result of the surgical treatment, was done. The statistical analysis was taken using the Yule-Kendall test and according to it for each factor the risk coefficient Q (from 0.8 to 1.0) was suggested. The group of factors conditioning in each case the failure of surgical procedure was noticed. There were differences in mortality after surgical treatment of RAAA -from 41.2% to 83.3%, mean 63.6%. The mortality of 100% was ascertained in patients with Q above 3.5. The correlation between number of patients with expected risk factors and increasing mortality rate was done. This method is useful for explaining divergences in results of surgical treatment in patients with RAAA and may be helpful for qualification of patients for surgical procedure.
