ABSTRACT
BACKGROUND
Stroke continues to be one of the most debilitating disease that either leads to disability or
morbidity among different ethnicities in the world. In 2008 WHO had estimated deaths by
stroke to be 5.7million worldwide which has now risen to 6.24million deaths and projected to
be at 7.8million deaths by 2030. The current advancement of technology makes it possible to
recognize stroke at an early stage and hence treatment can be planned accordingly. One of
such tools is the use of CTA which can be used to outline the cause of stroke and can further
be used to pinpoint the location of the problem and hence making it easier for the clinicians to
carry out the required interventional procedures. Therefore, it is imperative to apply the use of
CTA in sorting outpatients with stroke especially since CT scanners are readily available even
in most of the developing countries.
BROAD OBJECTIVE
To determine Computed Tomography angiography findings in adult patients with stroke
presenting at the Radiology department, Muhimbili National hospital from September 2018 to
February 2019.
METHODOLOGY
The study was conducted at the Radiology department at MNH by using a cross-sectional
analysis method and a convenience sampling technique. This study included 86 patients who
were diagnosed with stroke and were referred for CTA at the department. Images were
interpreted by the primary Investigator and proof-read by the Radiologist. When a difference
arose on the interpretation, a senior Radiologist was consulted and results recorded when the
consensus was reached. A well-structured questionnaire was used to collect data which were
later on analyzed using SPSS version 20. Data was presented in simple frequency tables and
charts. Statistical Association of descriptive data was done using chi-square. A p value of
<0.05 was considered significant. All images were obtained using the ALARA technique.

RESULTS
This study included 86 stroke patients, among which males were 45 and 41 were females. The
age range was between 18-95. Ischemic stroke was found to have a higher prevalence (60.5%)
compared to hemorrhagic stroke (39.5%). Of the angiographic patterns examined, stenosis was
found to be the commonest abnormal pattern represented by 36%, of which most occurred
intracranially (72.2%) as compared to extracranial (27.8%). MCA was the commonest affected
vascular territory (29.4%). Among the four modifiable risk factors, hypertension and diabetes
mellitus were the only two that had a strong association with stenosis.
CONCLUSION
Stenosis was the commonest abnormal angiographic pattern seen in patients with stroke with a
higher prevalence in intracranial segments (72.2%). Among the vascular territories analyzed,
MCA had a high prevalence of all. Anterior circulation showed high preponderance as
compared to posterior circulation. Hypertension and diabetes mellitus were the two risk
factors that showed a significant association with the stenosis (p-value <0.05). |
