What causes splenic artery rupture?

What causes splenic artery rupture?

Atherosclerotic disease (cholesterol buildup in arteries) may also lead to the formation of some aneurysms. Certain genes or conditions such as fibromuscular dysplasia can result in aneurysms. Pregnancy is often linked to the formation and rupture of splenic artery aneurysms.

What comes off the splenic artery?

The splenic artery or lienal artery is the blood vessel that supplies oxygenated blood to the spleen. It branches from the celiac artery, and follows a course superior to the pancreas. It is known for its tortuous path to the spleen….

Anatomical terminology

What size should a splenic artery aneurysm be?

The size of splenic artery aneurysms can range from 2 to 9 cm, but usually, it is smaller than 3 cm. Those may be single or multiple and are most commonly involving the distal portion of the artery. Peripheral calcification is common, and mural thrombus may be present 12.

How rare is a splenic artery aneurysm?

Splenic artery aneurysms are the most common visceral arterial aneurysm and third most common abdominal aneurysm, with an incidence of 0.1%–10.4%.

What is splenic artery?

The splenic artery is one of the three branches of the celiac trunk, which supplies the spleen as well as large parts of the stomach and pancreas.

What happens when a splenic artery aneurysm ruptures?

Patients with splenic artery aneurysm are usually asymptomatic, only 20% of them have symptoms such as abdominal pain, chest pain and most are diagnosed incidentally. Splenic artery aneurysm can be complicated by rupture resulting in hypovolemic shock, which could be fatal if not treated properly.

What does splenic artery mean?

Splenic artery: A large artery within the abdomen that arises from an arterial vessel called the celiac trunk, which emerges from the aorta. The splenic artery supplies blood not only to the spleen, but also to the esophagus, stomach, duodenum, liver, and pancreas.

Where does splenic artery end?

It runs anterior to the left kidney and suprarenal gland, and posterior to the stomach, through the peritoneal splenorenal ligament and along the tail of the pancreas. Its tortuous course allows the spleen and stomach to distend without compromising their blood flow….Splenic artery.

Origin Celiac trunk
Supply Pancreas, stomach, spleen

How fast do splenic artery aneurysms grow?

The natural history is slow growth at 0.06 to 0.09 mm per year. The clinical concern is rupture, which occurs in 3% to 5%, with mortality rates near 10%, although these figures are lower than with other types of visceral aneurysms.

How do they fix a splenic artery aneurysm?

Fusiform true aneurysms are better treated with a stent graft (covered stent), while tortuous, saccular aneurysms are treated with aneurysmal coiling techniques. Pseudoaneurysms can be treated with embolization using liquid embolic agents to thrombose the inflow and outflow arteries or filling the sac itself.

What level is the splenic artery?

The splenic artery is one of the three main branches of the celiac trunk, along with the left gastric and common hepatic arteries. It arises around the level of the lower border of the T12 vertebra.

What is the function of the splenic artery?

The splenic artery is responsible for supplying oxygenated blood to the spleen, but also has several branches that deliver blood to the stomach and pancreas. The branches of the splenic artery are the short gastric, the left gastroepiploic, the posterior gastric, and the branches to the pancreas.

What causes splenic aneurysm?

Causes. There are several causes of this condition.

  • Signs and Symptoms. The signs and symptoms often vary.
  • Diagnosis. The majority of splenic artery aneurysms are not diagnosed until they rupture,but occult aneurysms or calcified aneurysms may be seen when diagnostic imaging is done for another reason.
  • Treatment.
  • Prognosis and Complications.
  • Resources.
  • Is a splenic aneurysm dangerous?

    Splenic artery aneurysm is a rare condition, however, potentially fatal. The importance of splenic artery aneurysm lies in the risk for rupture and life threatening hemorrhage. PRESENTATION OF CASE This is a case of a ruptured splenic artery aneurysm in a 58-year-old lady. She presented with hypovolemic shock and intra-peritoneal bleeding.

    Why is splenic artery tortuous?

    Why is splenic artery tortuous? The difference in the increasing length of the artery and the distance between its origin and the splenic hilum makes the artery tortuous . The proximal part of the artery is more tortuous than the distal part [7].
