Gastroduodenal artery (GDA) aneurysms are particularly rare and only 1.5% of all visceral artery aneurysms in the literature.1 The possible etiologies of GDA aneurysms are vascular abnormality such as fibromuscular dysplasia, systemic lupus erythematosus, polyarteritis nodosa, and predisposing events, which included pancreatitis, abdominal trauma, or major abdominal operation.2 The clinical presentation can vary widely, including asymptomatic anemia, a palpable pulsatile mass, gastric outlet obstruction and fatal gastrointestinal bleeding.3
To conclude, gastroduodenal artery aneurysms are extremely rare, there is only a limited knowledge concerning the clinical presentation and best treatment.
Catheter angiography remains important in the visualisation and measuring of the exact gastroduodenal artery
pathology and artery width, and presence of arteriovenous fistula.
The incidence and supply type of gastroduodenal artery
bile duct branch
This demonstrated a pseudoaneurysm involving a segmental branch of the gastroduodenal artery
(Figs 1 and 2).
Corresponding vessels were gastroduodenal artery
(n = 3), Jejunal branches of SMA (n = 2), and a single case from right ileocolic and left gastric arteries each.
In the routine dissection of 34 year old male cadaver, we observed a case of the cystic artery (CA) having an origin from the gastroduodenal artery
( GDA) 2.5cm distal to the origin of common hepatic artery (CHA) (Fig.
(3) In the present study, the cystic artery was arising from right hepatic artery in 57 specimens [95%], from accessory right hepatic artery in 2 specimens [3.3%] and from gastroduodenal artery
in one specimen [1.66%].
Among those, six (6.74%) celiac trunks, emitting as fourth branch a gastroduodenal artery
Thrombosed pseudoaneurysm of gastroduodenal artery
was found with mass effect on portal vein and CBD.
1), becomes the gastroduodenal artery
and originates two more arteries, one with branches for the caudate, right lateral, right medial lobes an the gall bladder (cystic artery).
Its branches are Gastroduodenal artery
, right gastric artery, right and left hepatic arteries.
