Abstract:BACKGROUND: Considering the paucity of information presently available concerning inferior phrenic arteries, a more definitive study seemed appropriate and necessary, both for its potential clinical applications and to provide additional data to contemporary anatomical literature. OBJECTIVE: Most anatomical textbooks of gross anatomy offer very little information concerning the anatomy and distribution of the inferior phrenic artery (IPA). For that reason, the origin of the IPA has been studied and the availab… Show more
“…The inferior phrenic arteries (IPA) of right and left side arise as lateral branch from the abdominal aorta, but in the present case, the left IPA arises from the LGA also reported by Pulakunta et al (2007) and Silveira et al (2009). During hepato-cellular carcinoma (HCC), the IPA is the most frequent artery establishes the extra-hepatic collateral circulation because this artery is in close contact between the posterior part of liver and diaphragm at the bare area of the liver.…”
SUMMARY:The knowledge of abdominal vascular anatomy is very important for surgeons and radiologists to perform many of the clinical diagnostic evaluations. The celiac trunk, one of the branches of the abdominal aorta shows numerous variations in its branching pattern and its branches. The present study is to demonstrate the rare branching pattern of celiac trunk, into hepatogastric and hepatosplenic trunks. The hepatogastric trunk divided into left gastric and accessory left hepatic arteries and the hepatosplenic into common hepatic and splenic artery. The inferior phrenic artery was arising from left gastric artery. The gastroduodenal artery divided into right gastroepiploic artery and a common trunk for right gastric and anterior superior pancreaticoduodenal artery. The posterior superior pancreatico-duodenal artery was arising directly from the gastroduodenal artery and supraduodenal from proper hepatic artery. The variant anatomy of the celiac trunk as found in the present case may be clinically significant during invasive procedures like angiography, chemotherapy, chemoembolization and other surgical conditions of the abdomen.

“…According to Nayak SR. [15] the left inferior phrenic artery was seen to take origin from the celiac artery as its first branch. In another study done by Pulakunta T. [16] the inferior phrenic artery showed a variant origin in four out of 32 cases. It was seen to arise directly from the celiac trunk in two cases and there was one case arising from the left gastric artery and another from the right renal artery.…”
ABSTRACT:The knowledge of the anomalous arterial branching patterns is essential from the view point of surgical anatomy, especially while contemplating hepatic and pancreatic surgeries. The anatomical variations of the celiac trunk, superior mesenteric artery, renal and gonadal arteries are well established. The presence of anomalous origin of the inferior phrenic artery from the celiac trunk is comparatively rare in available literature but is clinically very important because this may act as a major source of collateral or parasitized arterial supply to hepato-cellular carcinoma, second only to the hepatic artery. The present study was carried out from the data collected over a period of four years when routine dissection was done while teaching the first year MBBS undergraduate students. The arterial branching pattern of the coeliaco-mesenteric axis was noted down from a total of 40 cadavers (10 each year) and any anomalous pattern observed was documented. In our study we observed a lower origin of the celiac trunk through the substance of the pancreas in 3 cases, presence of two separate trunks namely gastro-splenic and hepato-mesenteric arising from the abdominal aorta in 4 cases and both inferior phrenic arteries arising from celiac trunk in 1 case. The remaining 32 cadavers had normal arterial branching pattern. These anomalies could cause a catastrophe during surgical procedures, especially laparoscopic ones if the same is not kept in mind before contemplating pre-operative investigations. The awareness of these vascular anomalies is very important while contemplating radiological and surgical interventions. Therefore keeping in mind the immense radiological and surgical importance of these variations, the continuous reporting of such cases is significant.
“…They also noted alternative origins (left gastric, hepatic, superior mesenteric, and spermatic), stating that such origins occurred with <4% frequency on either the right or left side. Pulakunta T et al 13 did a study on 32 cadavers observed the origin of the inferior phrenic arteries from the celiac trunk in two specimens (6.25%), one from the left gastric artery (3.125%) and one from the right renal artery (3.125%) out of the 32 cadavers. In the remaining 28 specimens it had its normal origin from the abdominal aorta.…”

“…17 Extensive knowledge of all possible variations of inferior phrenic artery origin will provide valuable data to researchers, clinicians and anatomists alike. These data will useful for the management of liver transplants and biliary tract surgery, 13 enhancing the understanding of both the specific anatomy of the inferior phrenic arteries as well as their potential significance in supplying hepatocellular carcinomas and other liver tumors, primary or metastatic, such as cholangiocarcinoma, hepatoblastoma and subcapsular adenoma. 18 It is also useful in evaluating the efficacy and safety of Tans catheter oily chemo embolization technique via inferior phrenic artery, discussion and treatment of other hepatic, suprarenal or even diaphragmatic lesions.…”

“…14 The left inferior phrenic artery is major source of blood supply during occlusion of right and left gastric arteries. 13 Information of inferior phrenic artery variations is necessary to avoid unintentional sectioning of these small calibre arteries, as it may be seen during decompression in compression syndrome of the celiac trunk by the median arcuate ligament. 19 …”
