Early and midterm outcomes of in situ laser fenestration during thoracic endovascular aortic repair for acute and subacute aortic arch diseases and analysis of its complications

In Situ Laser Fenestration for Delayed Left Subclavian Artery Revascularization Following Thoracic Endovascular Aortic Repair of Type B Aortic Dissection

“…Among them, ISLF has been widely used because of its good security and high success rate. 7,8 Moreover, reports of in situ fenestration have shown satisfactory results in terms of short- to midterm patency. 7,8 There have been no reports on the application of ISLF for delayed revascularization of the LSA previously sealed in TEVAR.…”

“…7,8 Moreover, reports of in situ fenestration have shown satisfactory results in terms of short- to midterm patency. 7,8 There have been no reports on the application of ISLF for delayed revascularization of the LSA previously sealed in TEVAR. In this article, we report 5 cases in which ISLF was utilized to achieve delayed revascularization of the LSA, including 4 successful cases (80%) (Figure 1) and 1 failed case (20%) (Figure 4).…”

“…To minimize trauma, conventional ISLF of the LSA was performed. 7,8 We utilized the VELAS laser system (GIGAA Laser, Wuhan, China), which was calibrated to deliver energy pulses of 18 W in 3 seconds, to fenestrate the membrane of the thoracic aortic stent graft. After fenestration, balloons 3 mm, 5 mm and 8 mm in size (Mustang; Boston Scientific, MA) were used to pre-expand the fenestration.…”

“…5,6 In situ laser fenestration (ISLF) is an important technique for reconstruction of the aortic major branches during TEVAR, with satisfactory effects on early and midterm follow-up. 7,8 To our knowledge, there have been no reports on the application of ISLF for delayed revascularization of the LSA previously sealed in TEVAR. In this article, we report 5 cases in which ISLF was utilized to achieve delayed revascularization of the LSA, including 4 successful cases (80%) and 1 failed case (20%).…”

Gimme’ the Loop: Modifications to the Squid-Capture Technique for Laser-Fenestrated Thoracic Endografting

“…13 The largest and most recent study to this point analyzed outcomes of 148 patients undergoing LfTEVAR for acute and subacute aortic arch diseases. 14 In their cohort, the authors reported 4 cases with technical failure during laserassisted fenestration. Again, all of these were due to acute angle between laser device and thoracic stent graft.…”
