Fig. 1: Descriptive analysis of the data
1-Table 1.
Descriptive analysis of the data.
The total number of patients included in the study was (n=473),
of whom there were (n=214) males and (n=259) females.
Males constituted 45.2% of the study sample,
whereas females constituted 54.8%.
There was a statistically significant difference in terms of the proportions of men and women in the study sample (p = 0.019).
Females outnumber males by 9.5%.
2-In terms of age,
the mean age was 63.1 years (Standard Deviation (SD) = 17.4 years,
Range between 16 and 98 years)
3- The most common presenting symptom was chest pain,
51.6% (n=244) followed by dyspnoea,
49% (n=232) and pleuritic chest pain,
35.5% (n=169).

Fig. 2: Comparison of findings between patients with or without PE

Chart 1 showing that,
for patients with suspected PE,
the symptom profile was very similar whether PE was present or not.
5.
In this study 100% of the patients that had CT proven PE had elevated D-Dimer of more than 0.5mg/L
6.
84.1 % of the patients that had an elevated D-Dimer actually negative for PE
CLINICO-RADIOLOGICAL AGREEMENT
Of the 473 patients suspected clinically to have PE,
63 (13.3%) were found to have CTPA proven PE.
Given the seriousness of the PE diagnosis,
the positive predictive value is expected to be low.
This frequency of positive PE is in line with international studies(6).
HISTOPATHOLOGICAL-RADIOLOGICAL AGREEMENT
Agreement between incidental radiological findings and subsequent histopathological findings was found in 89% (8/9) cases.
Incidental neoplasia detected were small and non small cell lung carcinoma,
non Hodgkin’s lymphoma,
leiomyosarcoma and renal cell carcinoma.
