What is splenic artery aneurysm coiling?

What is splenic artery aneurysm coiling?

Splenic artery aneurysms (SAAs) are the third most common abdominal aneurysm. Endovascular treatment of SAAs is preferred, and coiling is the most commonly used technique. Ruptured giant (>5 cm) SAAs are usually treated with open surgery including splenectomy.

What is a coil embolization?

Coil Embolization Coiling involves insertion of a catheter into the femoral artery in the patient’s leg and navigating the catheter through the vascular system into the patient’s head and to the aneurysm. The entire process is done using continual X-ray visualization and high-speed radiographic filming techniques.

What is a splenic artery embolization?

Splenic (artery) embolization is an endovascular technique for treatment of splenic and splenic artery pathology as an alternative to splenic artery ligation or splenectomy. It often results in successfully treating the underlying pathology, while maintaining at least partial splenic function.

How is splenic artery embolization done?

Depending on vascular anatomy, a microcatheter system is used to select the distal main splenic artery or splenic artery branches for embolization, with postembolization angiograms completed from the base catheter.

How serious is a splenic artery aneurysm?

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.

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%.

How successful is aneurysm coiling?

The long-term success of endovascular coiling to treat aneurysms is about 80 to 85%. Aneurysm recurrence after coiling occurs in 20% of patients [3].

Can a coiled aneurysm rupture?

The risk of rupture from a coiled aneurysm during the late (≥ 1 year) follow-up period was small (annual rate 0.09%). The rate of requiring retreatment of a coiled aneurysm was relatively low (4.8%). However, more than half of the retreatments were performed more than 5 years after the initial treatment.

How is splenic artery aneurysm treated?

The treatment options again are open surgery (mandatory in the setting of rupture), endovascular procedures, and laparoscopic surgery. Open surgical procedures include ligation of the splenic artery or aneurysm and aneurysmectomy with or without splenectomy.

When do you treat a splenic artery aneurysm?

In the absence of guidelines, the main recommended indications for intervention of splenic artery aneurysm are rupture, aneurysm size larger than 2 or 2.5 cm, growth of the aneurysm by 3 to 5 mm or more during surveillance regardless of initial size, symptoms, women of childbearing age, portal hypertension, and planned …
