Shockwave lithotripsy facilitates large-bore vascular access through calcified arteries

Abstract

Background Our objective is to explore the Peripheral Intravascular Lithotripsy (IVL) System in the treatment of calcific access vessels during thoracic endovascular aortic repair (TEVAR), endovascular aortic repair (EVAR), and transcatheter aortic valve intervention. Methods This retrospective, single-center study evaluated the outcomes of patients undergoing TEVAR, EVAR, or transcatheter aortic valve intervention with severe calcific arterial disease between July 2018 and August 2019. Maximum circumferential calcification, length of calcification, and inner/outer diameter measurements were collected with curved planar reformation by medical imaging software (Aquarius APS, TeraRecon, Foster City, Calif). Effective luminal gain was calculated using the minimal inner diameter and the largest bore passed within the vessel lumen. End points included technical success, mortality, adverse events, and requirement for bail out maneuvers. Technical success was defined as successful delivery and deployment of device or endograft. Results Nine patients were included (mean age, 79.3 ± 9.79 years; range, 59-97 years]). four transcatheter aortic valve replacement, one TEVAR, one EVAR, and three fenestrated EVAR. Six patients (66.7%) had more than one artery treated; the segments treated included common iliac artery (seven patients [77.8%]), the external iliac artery (seven patients [77.8%]), and the common femoral artery (one patient [11.1%]). The average inner iliac vessel diameter was 3.38 ± 0.99 mm (range, 1.87-4.72 mm). The average outside diameter of device introduced was 7.2 ± 0.94 (range, 6.3-8.8 mm) with 229% effective luminal gain. Technical success was achieved in 100% of cases with a 0% mortality. Adjunctive measures were needed in five cases (55.6%). One vessel perforation was controlled with covered stent (Viabahn; W. L. Gore & Associates, Flagstaff, Ariz) deployment. Dissection was identified in two cases requiring stent placement. Two cases required the use of the Terumo International Systems SOLOPATH Balloon Expandable TransFemoral System (Terumo Interventional Systems, Somerset, NJ). One case deployed a Viabahn stent applying the “crack and pave” technique. Conclusions As the population of the United States ages, calcified arterial disease will become an everyday clinical conundrum. Furthermore, the procedures for which the IVL system is geared toward facilitating will likely also increase in use. The IVL system is an additional tool in the vascular surgeon's armamentarium to obtain large-bore access in these calcified vessels. Further studies are needed to better assess the clinical effectiveness of the IVL system.

Renal intravascular shockwave lithotripsy in complex mono Ch-EVAR

“…At any rate, those complications can be treated with a covered self-expandable stent. 9 Finally, this system is compatible with currently available pacemakers and defibrillators. 6 Shockwave IVL has proven to be safe and effective in the treatment of peripheral arterial disease 3–5 and to facilitate large-bore access to enable EVAR 9 and TAVR.…”

“…9 Finally, this system is compatible with currently available pacemakers and defibrillators. 6 Shockwave IVL has proven to be safe and effective in the treatment of peripheral arterial disease [3][4][5] and to facilitate large-bore access to enable EVAR 9 and TAVR. 10 More recently, Danielle Lee et al utilised this technique for renal arteries revasculatisation.…”

“…Contraindications to this device include an inability to pass a 0.014-inch wire past the lesion and in-stent restenosis. 9 Since calcified renal arteries are prone to complications during revascularization, the introduction of Shockwave IVL has afforded safer treatment options with decreased risk of perforation, dissection or distal embolisation. Indeed, Shockwave angioplasty can be performed with lower pressures minimising arterial dissection and enhancing vessel compliance.…”
