Is splenic embolization painful?
Postembolization syndrome of fever, left upper abdominal pain, nausea, and anorexia are extremely common after splenic artery embolization. All patients should be given patient-controlled analgesia (PCA) for pain control.
How fast do splenic artery aneurysms grow?
The mean aneurysm size at initial diagnosis was 1.67 cm for patients undergoing observation and 3.13 cm for the treated group (P < . 001). Endovascular repair was safe and durable with a mean 1.5-mm regression in SAA size over 2 years. The mean rate of growth for observed SAA was 0.2 mm/y.
Why is splenic artery coiled?
The placement of coils in a middle segment of the splenic artery allows reconstitution of the blood supply through collateral vessels, principally via the short gastric and gastroepiploic arteries, to the patent distal splenic, transgastric, and transpancreatic arteries.
How dangerous 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.
What is embolization of splenic artery?
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.
What is a splenic artery embolization?
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 would cause a splenic artery aneurysm to rupture?
Splenic Artery Aneurysm Risk factors for rupture include portal hypertension and pregnancy. Maternal mortality for ruptured splenic artery aneurysm is 75%, and fetal mortality is up to 95%.
Are there any complications after a splenic artery embolization?
Splenic artery embolization (SAE) has been increasingly used for treatment of splenomegaly/hypersplenism. However, few studies focused on the severe complications after embolization.
When to use splenic artery embolization ( SAE )?
In prior decades, splenic arterial embolization (SAE) was used increasingly in the setting of nonoperative management of blunt splenic trauma.
What kind of angiography is done for spleen embolization?
Celiac angiography is performed to evaluate not only the splenic artery anatomy but also sources of collaterals to the spleen, including the left gastric artery, gastroepiploic arteries, and pancreatic artery branches. Proximal splenic artery embolization, distal splenic artery embolization, or both can be performed.
Where is the microcatheter placed for splenic embolization?
For distal splenic artery embolization (Fig. 2), the microcatheter is placed as distally as possible in the injured splenic artery branches before embolization to preserve as much of the spleen as possible.
