Splanchnic artery aneurysm
What is it?
It is a dilation of the artery that carries blood to the intestine, primarily the celiac tripod, hepatic artery, splenic artery, and mesenteric artery. It is considered pathologic if it has a transverse diameter of more than one and a half times the normal diameter.
Causes and risk factors
The subjects most at risk are people who already have other diseases such as atherosclerosis with its associated risk factors (smoking, diabetes, dyslipidemia, hypertension), trauma, congenital diseases.
Which are the symptoms?
It is a predominantly asymptomatic condition. In some cases, it can cause artery rupture.
- Abdominal pain
How is it diagnosed?
In most cases, it is diagnosed occasionally, and, if found, further investigation is required.
How is it treated?
The therapy can be surgical or endovascular, depending on the case. Surgical treatment: implemented by replacing (bypass) the aneurysmal artery with a synthetic or biological prosthesis (saphenous vein). Endovascular treatment: feasible only in some cases. Percutaneous (without incisions) arteriography is performed and implantation of one or more covered stents (metal mesh tubes), or embolization of the aneurysm by thrombotic material.
