Background digitized hepatic angiography is an interventional procedure that uses iodine-containing contrast to image the splenic artery and vein. Digital splenic angiography erases background to help diagnose splenic diseases with angiogenesis, aneurysms and vascular malformations, thereby providing appropriate treatment.

1. When is the digitized splenic artery angiography indicated?

1.1 Designation

Splenic artery pseudoaneurysm
Gastrointestinal bleeding
Splenic rupture trauma
Hypersplenism syndrome
Splenic lymphoma
Chronic lymphocytic leukemia
Preoperative laparoscopic splenectomy .

1.2 Contraindications

● Severe and uncontrolled coagulopathy (prothrombin <60%, INR > 1.5, platelet count < 50 G/l): Need to be adjusted before intervention
● Severe renal failure
● Allergic to contrast agent Photonic contains Iodine
● Pregnant women.

2. Digital splenic angiography with background erasure

2.1 Personnel

2 interventional radiologists 1 nurse 2 radiology technicians 1 anesthesiologist if the patient is uncooperative or the child is under 5 years old. 1 anesthesiologist

2.2 Vehicles and machines

● Digital erasure angiography (DSA)
● Specialized high-pressure contrast agent pump.
Pacs image storage system.
● Lead jacket, apron, lead collar, x-ray shielding glasses.

2.3 Implementation steps

● Patients and guardians are explained about the procedure, benefits, risks of complications - possible complications. Sign a commitment to do the procedure, commit to using contrast agents containing iodine.
● Fasting, drinking before 6 hours if anesthesia; 4 hours before anesthesia. You can drink water but not more than 50ml of water.
● At the intervention room: the patient lies on his back, installing a monitor to monitor breathing, pulse, blood pressure, electrocardiogram, SpO2.
● Disinfect the femoral artery puncture area, cover with a vascular intervention towel set.
● Local anesthesia of femoral artery puncture with Lidocaine 2%
● Fetal artery puncture. In special cases, a radial puncture can be performed if femoral artery puncture is not possible. Placement of an arterial catheter
● Thread the catheter onto a visceral angiogram to assess the overall splenic artery.
● Superior mesenteric angiogram to evaluate the splenic-portal venous system.
● Selective splenic artery scan, identify damaged blood vessels, use microcatheter to thread super selectively into the pedicle supplying blood to the lesion.
● Conduct embolization with materials suitable for indications through microcatheter.
● Take a scan to check the occlusion of the feeding vessels, continue selective embolization if necessary.
● Remove the catheter and open the catheter into the lumen.
● At the end of the procedure, compress the femoral artery or close the femoral artery.
● The patient lies on the hospital bed, immobilizes the leg on the side of the puncture, the nurse will monitor for bleeding complications ~ 8 hours if the bandage is pressed, ~ 2 hours if the femoral pulse is closed.
● Monitor pulse, temperature, blood pressure, respiratory indicators.
● Use pain relievers and antiemetics in case of need.
