Interventional Radiologist (Dr. SAMEER) Describes a New Procedure for Splenic Artery Pseudoaneurysm Embolization: Sequential aspiration and injection of a gelatin-based hemostatic agent and autologous blood clot, followed by suture coiling

In a recent case, a 49-year-old man with severe acute pancreatitis presented with signs of severe bleeding due to a large pseudoaneurysm of the splenic artery. The patient underwent percutaneous direct embolization of the pseudoaneurysm using a novel technique known as the SAMEER technique.

The SAMEER technique, while not extensively detailed in the available literature, is a specific percutaneous approach for embolizing splenic artery pseudoaneurysms. The acronym SAMEER typically stands for a stepwise method or mnemonic used in radiological interventions, but the exact steps or the full form of SAMEER in this context are not readily available.

The general principles of the SAMEER technique involve image-guided access, puncture of the pseudoaneurysm or feeding artery, and the delivery of a mixture of a gelatin-based hemostatic agent and autologous blood clot to occlude the aneurysm and prevent bleeding. The procedure also includes suturing the aneurysm sac and sealing the needle puncture tract.

The patient's condition improved significantly after the procedure. At a follow-up doppler ultrasound at 3 weeks, the aneurysm showed complete occlusion and no signs of recanalization. His hemoglobin level was recorded at 9.4 g/dL, and his vitals were stable.

Pseudoaneurysms of the splenic artery lack a well-defined wall and are predisposed to rupture, which may lead to hypotension and shock. Treatment of splenic artery pseudoaneurysms is considered a priority in the management of pancreatitis due to the risk of rupture.

In cases where endovascular embolization is not feasible, percutaneous image-guided direct puncture and embolization of the pseudoaneurysms is a valuable option. This report describes a novel technique of percutaneous embolization of splenic artery pseudoaneurysms with Sequential Aspiration and Injection of a Mixture of gelatin-based hemostatic agent and autologous blood clot followed by suture coiling (SAMEER technique).

While more detailed information about the SAMEER technique can be found in specialized interventional radiology literature, this case demonstrates its potential as a safe and effective treatment option for splenic artery pseudoaneurysms.
