– Male patient, 61 years old, anesthesiologist, cigarette smoker, hypertensive. He begins experiencing intense abdominal pain. Hb reduction, 14-11 g/dL. He is hemodynamically stable; blood pressure 110/60 mmHg, heart rate 68 bpm. An abdominal computed tomography angiography shows the contained rupture of an abdominal aneurysm. Anatomy: juxtarenal aneurysm without neck, with small, tortuous iliac arteries.

Case Resolution

– The algorithm for the attention of patients with suspected abdominal aneurysm rupture is activated. Physicians choose a percutaneous endovascular treatment (the chimney technique [chEVAR]).

– The procedure is conducted in a hybrid cath lab; bilateral femoral artery puncture, guided by ultrasound and image fusion. Two Perclose devices are used in each femoral artery. Both brachial arteries are dissected; an 8-Fr flexor introducer sheath is placed inside each renal artery. Selective renal artery catheterization and stenting using an 8×39 film-coated BeGraft (Bentley Innomed GmbH, Hechingen, Germany). A parallel 0.035” Magic Torque guidewire ×260 cm is used. Then, an Ovation 26 Abdominal Stent Graft System (Endologix, California, USA), 14-15 Fr OD, is used. The device is placed using image fusion, the fill polymer is delivered, and both BeGraft stents are implanted. After the procedure, there is a type Ia endoleak in peri-chimney spaces (“gutters”). New dilation conducted with partial improvement. A decision is made to conduct an embolization with an Onix device at a second instance.

– The patient is stable and does not experience pain. An ultrasound is conducted within 24 hours: no flow in the aneurysm sac.

– A computed tomography angiography is conducted at 72 hours, 1, 6, and 12 months; no endoleaks. (VIDEO #2)

Questions

1. Is there an algorithm for the attention of patients with suspected abdominal aneurysm rupture at your site?
2. In your opinion, what is the best option for a patient with aneurysm rupture: surgical treatment or endovascular treatment?
3. What is your treatment of choice for para/juxtarenal aneurysms?
4. Should type I endoleaks be treated in the cath lab?
