Successful Percutaneous Coil Embolization of a Ruptured Internal Iliac Artery Aneurysm Remnant after Abdominal Aortic Aneurysm Repair via the Deep Iliac Circumflex Artery

Coil Embolization of Recurrent Internal Iliac Artery Aneurysm via the Superior Gluteal Artery

We report a case of recurrent internal iliac artery aneurysm previously treated with a combination of stent graft placement and coil embolization in an 85 year-old male patient. The patient was scheduled for the direct puncture embolization of the superior gluteal artery. The patient was placed in a prone position under general anesthesia. An 18G-PTC needle was inserted into the superior gluteal artery under ultrasonographic guidance. A 2.2F microcatheter was inserted through an outer needle and advanced to the aneurysmal sac. Coil embolization was successfully performed without endoleaks. This approach is technically feasible when other treatment options fail or are deemed unsuitable.

Embolization of a Previously Excluded Symptomatic Internal Iliac Aneurysm Through the Iliac Vein

A 69-year-old man was referred urgently for a 58-mm enlarging painful right internal iliac artery (IIA) aneurysm. Since exclusion through proximal IIA coverage and distal IIA branches embolization had been previously performed, aneurysm sac puncture through the iliac vein was decided. The ipsilateral common femoral vein was antegradely punctured, and a 16.5 G Ross modified Colapinto needle from a transjugular intrahepatic access set was used to puncture the sac and fill the aneurysm with coils. Embolization of an IIA aneurysm through the iliac vein may represent an alternative when prior IIA aneurysm exclusion has been performed.

Emergency Embolization of a Ruptured Aneurysm of the Internal Iliac Artery by Direct Ultrasound-Guided Puncture: Report of a Case

We report the emergency embolization of a ruptured aneurysm of the internal iliac artery in a patient at high surgical risk. Admission computed tomography scan showed that the ostium of the aneurysmal internal iliac artery was covered by a covered stent. In this patient, we chose to carry out an embolization of the aneurysm and its efferent arteries by direct puncture of the aneurysmal sac using an antero-external abdominal approach under ultrasound guidance. Short-term results were favorable and we consider that this technique is one of the therapeutic options to discuss in such situation.

Plug the Hole--A Bailout Option for Acute Focal Aortic Rupture

BACKGROUND

Focal aortic rupture may result from expanding aneurysms, penetrating aortic wall ulcerations, or virulent infections. An urgent repair of paravisceral focal aortic rupture is associated with high morbidity. A staged repair approach may provide an alternative option.

CASE REPORT

A 64-year-old woman presented with acute focal rupture of the posterior paravisceral aortic wall and was progressing to hemorrhagic shock and mesenteric ischemia. Given the patient's dire condition, an endovascular approach was used to plug her focal aortic wall defect using a ventricular septal defect occluder device. Subsequently, the patient underwent resuscitation, stabilization, and operative exploration. Postoperatively, she recovered well from this staged approach.

CONCLUSIONS

This case provides an example of a staged endovascular plugging of an acute paravisceral focal aortic rupture. In select cases, this type of repair strategy is feasible, until off-the-shelf endovascular repair options become a reality.
