Endovascular treatment of abdominal aortic rupture after percutaneous lithotripsy

INTRODUCTION

Extracorporeal shockwave lithotripsy (ESWL) is a type of urological intervention used for the treatment of stones smaller than 2 cm located in the renal pelvis or upper portion of the ureter(11 de Graaf R, Veith FJ, Gargiulo NJ 3rd, et al.

Potential complications of this procedure include subcapsular renal hematoma, pseudoaneurysm, arteriovenous fistula, abscess formation in the psoas muscle, thrombosis of the portal or iliac vein, and-the most disastrous and potentially fatal complication-abdominal aortic aneurysm (AAA) rupture(11 de Graaf R, Veith FJ, Gargiulo NJ 3rd, et al. Endovascular abdominal aortic aneurysm repair to prevent rupture in a patient requiring lithotripsy. J Vasc Surg. 2003;38:1426-9.,22 Neri E, Capannini G, Diciolla F, et al. Localized dissection and delayed rupture of the abdominal aorta after extracorporeal shock wake lithotripsy. J Vasc Surg. 2000;31:1052-5.).

Studies have shown that AAA is a potential risk factor for ESWL-induced arterial rupture(11 de Graaf R, Veith FJ, Gargiulo NJ 3rd, et al. Endovascular abdominal aortic aneurysm repair to prevent rupture in a patient requiring lithotripsy. J Vasc Surg. 2003;38:1426-9.,22 Neri E, Capannini G, Diciolla F, et al. Localized dissection and delayed rupture of the abdominal aorta after extracorporeal shock wake lithotripsy. J Vasc Surg. 2000;31:1052-5.), because of calcifications of the arterial walls resulting from atherosclerotic disease, given that the mechanical energy of the shockwaves can disperse up to 12 cm from the focal point; although the intensity of the waves decreases progressively as the distance from the target increases, they can still have a deleterious effect on parietal calcifications(44 Tse GH, Qazi HA, Halsall AK, et al. Shockwave lithotripsy: arterial aneurysms and vascular complications. J Endourol. 2011;25:403-11.). Despite the scarcity of studies on this topic, we believe that advanced age and short distances between vascular parietal calcifications and renal pelvis calculi may be risk factors for AAA rupture during ESWL.

There is not sufficient scientific evidence to define the safety of ESWL in patients with AAA, a controversial subject in the literature(11 de Graaf R, Veith FJ, Gargiulo NJ 3rd, et al. Endovascular abdominal aortic aneurysm repair to prevent rupture in a patient requiring lithotripsy. J Vasc Surg. 2003;38:1426-9.

In a review of the literature, Tse et al.(44 Tse GH, Qazi HA, Halsall AK, et al. Shockwave lithotripsy: arterial aneurysms and vascular complications. J Endourol. 2011;25:403-11.) discovered that, among the reported cases of patients with AAA who underwent ESWL, there were no vascular complications in 18, rupture of the AAA occurred in 6, and aortic rupture in a nonaneurysmal calcified aorta occurred in 2. In the present article, we will demonstrate the endovascular correction of abdominal aorta rupture in a patient submitted to ESWL.

PROCEDURE

Symptoms of AAA rupture may include severe low back pain, general malaise, nausea, vomiting, dizziness, and blurred vision. Physical examination may show pallor, hypotension, tachycardia, and a pulsatile abdominal mass. In cases of hemodynamic instability, the patient must first be stabilized, and, when possible, should undergo computed tomography (CT) angiography of the abdomen, which is the imaging modality of choice for the diagnosis and planning of endovascular treatment. Rupture of an AAA is more likely to occur in the retroperitoneal space than in the peritoneal cavity, mortality rates being higher if it occurs in the latter(44 Tse GH, Qazi HA, Halsall AK, et al. Shockwave lithotripsy: arterial aneurysms and vascular complications. J Endourol. 2011;25:403-11.).

When diagnosing AAA rupture by CT angiography (Figures 1 and 2), clinical patient stabilization measures must be taken together and despite a rapid endovascular approach, CT angiography has greater therapeutic potential than does conventional surgery because the former has a shorter execution time, less morbidity, and low technical complexity(77 Wanhainen A, Verzini F, Van Herzeele I, et al. Editorֹ's choice - European Society for Vascular Surgery (ESVS) 2019 Clinical Practice Guidelines on the Management of Abdominal Aorto-iliac Artery Aneurysms. Eur J Vasc Endovasc Surg. 2019;57:8-93.).

The endovascular approach begins in the hemodynamics room, with the patient in the supine position. Ultrasound-guided puncture of the right common femoral artery, by the Seldinger technique, is followed by insertion of a 6 Fr femoral introducer, a stiff guidewire, and a pigtail catheter for aortic angiography, aiming at planning the procedure, which will be involve coverage of the rupture site (pseudoaneurysm) with a coated stent (Figure 3A), through the use of a roadmap. A follow-up CT angiography is necessary in order to verify the proper positioning of the stent and that there is no extravasation of blood (Figure 3B). The type of post-procedure clinical support (semi-intensive or intensive) depends on the clinical status of the patient at admission rather than on the endovascular treatment in question.

Follow-up evaluation can be performed after one week at an outpatient clinic, and a follow-up CT angiography can be performed after 30 days. Patients should be reevaluated at 12 months after the procedure, with Doppler ultrasound evaluation of the abdominal aorta, iliac arteries, renal arteries, and superior mesenteric artery.
