مقدمه: این مطالعه با هدف مقایسه‌ی یافته‌های سی‌تی آنژیوگرافی (Computed tomography angiography) CTA و آنژیوگرافی 4 رگ در بیماران مبتلا به خونریزی ساب آراکنوئید (Subarachnoid hemorrhage) SAH انجام شد.
روش‌ها: این مطالعه‌ی مقطعی گذشته‌نگر به منظور مقایسه‌ی یافته‌های CTA و آنژیوگرافی 4 رگ در بیماران مبتلا به SAH انجام شد. داده‌ها از گزارش‌های رادیولوژی بیمارانی که تحت CTA و آنژیوگرافی مغزی قرار گرفتند، استخراج گردید.
یافته‌ها: تعداد 60 بیمار مبتلا به SAH شامل 32 زن (53/3 درصد) و 28 (46/7 درصد) مرد وارد مطالعه گردیدند. میانگین سنی شرکت‌کنندگان 9/6 ± 59/3 سال بوده است. 22 بیمار (37 درصد) دارای یافته‌های غیر طبیعی شامل 3 بیمار (13/7 درصد) دچار AVM و 86/3 درصد دچار آنوریسم مغزی بودند. از میان 22 بیمار، آنوریسم در 16 بیمار (72/7 درصد) توسط روش CTA تشخیص داده شد. داده‌ها نشان داد که روش CTA با دقت 81/8 درصد، حساسیت 72/7 درصد و اختصاصیت 100 درصد، قادر به شناسایی ناهنجاری‌های عروقی در بیماران مبتلا به SAH خودبخودی در مقایسه با روش آنژیوگرافی 4V می‌باشد. سطح زیر منحنی برای تشخیص آنوریسم و AVM توسط روش CTA، 0/632 (67-91 : CI 95%) (0/028 = P) بوده است. ارزش اخباری مثبت و منفی روش CTA برای تشخیص آنوریسم به ترتیب 10/9 و 83/6 بود. متوسط اندازه‌ی آنوریسم به طرز معنی‌داری در روش CTA کمتر از روش آنژیوگرافی 4V می‌باشد (5/44 در برابر 7/11 میلی‌متر) (0/04 = P).
نتیجه‌گیری: نتایج مطالعه‌ی حاضر نشان داد که روش CTA دقت و اختصاصیت قابل قبولی در تشخیص آنوریسم و AVM در SAH خودبخودی در مقایسه با روش آنژیوگرافی 4V دارد.

چکیده [English]

Background: This study was conducted to compare the findings of computed tomography angiography (CTA) and 4-vessel Angio angiography (4V) in patients with subarachnoid hemorrhage (SAH).
Methods: This retrospective cross-sectional study was conducted to compare the findings of CTA and cerebral angiography in patients with SAH. Data were extracted from radiology reports of patients who underwent CTA and cerebral angiography.
Findings: We included 60 patients with SAH, comprising 32 women (53.3%) and 28 men (46.7%). The mean age of the participants was 59.3 ± 9.6 years. 22 patients (37%) had abnormal findings, including three patients (13.7%) with AVM and 86.3% with aneurysm. Among 22 patients, the aneurysm was diagnosed in 16 patients (72.7%) by CTA method. The data indicates that the CTA method has an 81.8% accuracy, 72.7% sensitivity, and 100% specificity in identifying vascular abnormalities in patients with spontaneous SAH compared to the 4V angiography method. The area under the curve for diagnosing aneurysm and AVM by CTA method was 0.632 (91-67: 95% CI (P = 0.028). The positive and negative predictive values of the CTA method for aneurysm diagnosis were 10.9 and 83.6, respectively. The mean size of the aneurysm was significantly lower in CTA than in 4V angiography (5.44 vs. 7.11 mm) (P = 0.04).
Conclusion: The results of the present study showed that the CTA method has acceptable accuracy and specificity in diagnosing aneurysm and AVM in spontaneous SAH compared to the 4V angiography method.
