Background: The inferior phrenic arteries are the rst branch of abdominal aorta. It is necessary to be familiar with the
anatomy of the inferior phrenic arteries in surgical and traumatic vascular injuries, haemoptysis, especially due to
pulmonary pathologies located in the lung base, and gastroesophageal haemorrhage from the gastroesophageal junction. It is the most common
extra-hepatic supply of hepato-cellular carcinomas. TACE is the treatment of choice for unresectable and advanced hepatocellular carcinomas.
Knowledge of the detailed arterial anatomy is required for successful embolization by TACE and to prevent complications. Data set Methods:
consisted of 150 patients who underwent triple phase CT angiography in GI bleed protocol. The association of CA variation with common trunk,
RIPA and LIPA, Chi-square test was used. RIPA most commonly originated from abdomina Results: l aorta in 88 (58.7%) patients followed by
celiac artery 45 (30%). LIPA most commonly originated from abdominal aorta in 77 (51.3%) patients followed by celiac artery 69 (46%). There
was no statistical signicance detected between the common truncus of IPA, RIPA & LIPA with celiac axis variations. The anatomy Conclusion:
and variations in the origin of inferior phrenic arteries are clinically important and should be evaluated with CTA prior to the surgical or
interventional management. In our study we did not nd any relationship between the origin of the common trunk of IPA, LIPA and RIPA with
celiac axis variations. The variations in the origin of inferior phrenic arteries and celiac axis variations can be explained by their embryological
development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
