Abstract

Background: CT angiography (CTA) is the initial modality for diagnosing the Carotid Cavernous Fistula (CCF), identifying the type of CCF, measuring the diameter of the fistula and the diameter of the internal carotid artery (ICA) pre and post fistula, and then confirmed by Digital Subtraction Angiography (DSA) as the gold standard. CTA is expected to provide more information to improve the accuracy of CCF diagnosis to benefit therapy and prevent complications. This study aimed to determine the diagnostic value of CTA in CCF patients in Dr. Soetomo General Hospital Surabaya, using the DSA as a gold standard. Methods: An observational retrospective study of CCF patients met the inclusion and exclusion criteria and underwent CTA and DSA examinations at the Radiology Installation of Dr. Soetomo General Hospital, Surabaya, from January 2016 to July 2020. Results: In the comparison of types of CCF CTA to DSA, the direct group was 53.8% and 57.7%, respectively, while the indirect group was 46.1% and 42.3% with a very strong correlation (κ = 0.922; p = 0.000), sensitivity was 93.3%, specificity was 100 %, PPV of 100%, NPV of 91.7% and accuracy of 96.15%. Direct type evaluation on the DSA showed a large picture of the fistula diameter; the ICA pre fistula's size was enlarged; therefore, the ICA post fistula diameter was reduced or absent. There was a strong correlation of fistula diameter measurement results between CTA and DSA (r = 0.695, p = 0.006). Conclusion: CTA has a similarity rate of 92.2% with DSA in identifying the type of CCF. The accuracy value of CTA is close to DSA in fistula diameter measurements.

Abstract

Hepatoblastoma is one of the most common primary malignant liver tumors in children. The incidence of hepatoblastoma has been increasing, reaching 1.2 per million children now. The transarterial chemoembolization (TACE) procedure is one of the most practical and effective treatment options besides surgery. Digital subtraction angiography (DSA) is performed as the first step of the TACE procedure. The aim of this study was to provide information about the feeding arteries and enhancement pattern of the hepatoblastoma that was assessed by DSA before the TACE procedure. A retrospective study was conducted among hepatoblastoma cases that had undergone DSA on the TACE procedure to obtain information on the vascularity of the tumor. A total of 26 hepatoblastoma cases who had DSA examination as a part of their first TACE procedure were included, consisting of 15 boys and 11 girls, aged between 1–15 years. All cases were stage III and IV according to the Pre-Treatment Extent of Tumor (PRETEXT) staging classification. All hepatoblastoma cases had multiple feeding arteries, most of which were branches of the right hepatic artery. The largest diameter of the feeding artery was 1.82 mm, and the smallest was 0.63 mm. Most cases (84.62%) had strong contrast absorption, and spread evenly, either at the edges or in the center of the tumor. DSA is believed to be an accurate procedure to provide a detailed description of the feeding artery; enhancement patterns of hepatoblastoma were influenced by an adequate TACE.
