Combined proximal descending aortic endografting plus distal bare metal stenting (PETTICOAT technique) versus conventional proximal descending aortic stent graft repair for complicated type B aortic dissections

One-stage supraclavicular hybrid procedure for type B aortic dissection involving three rare anatomical anomalies: a case report and literature review

“…We deployed a bare metal stent distally because it was favorable in the short-term. 27,28 This is the first report describing supraclavicular hybrid TEVAR for a patient with TBAD combined with three rare anomalies.…”

Early results of bare metal extension stent for thoracoabdominal aortic dissection

“…8 The provisional extension to induce complete attachment (PETTICOAT) stent technique to treat acute type B aortic dissection has demonstrated efficacy in expanding the true lumen in the abdominal aorta. 12,13 Systematic reviews by Rong and colleagues 13 and Bertoglio and colleagues 14 both reported improved remodeling of the distal thoracoabdominal aorta at 12 months using the PETTICOAT technique, although studies were nonrandomized and primarily focused on patients with acute Debakey IIIb dissection with malperfusion. Few studies have focused on utilizing the PETTICOAT technique in chronic Debakey I/IIIb dissections to encourage distal thoracoabdominal aortic remodeling and reduce the need for thoracoabdominal aortic surgery or branched thoracoabdominal endovascular repair.…”

A reversed strategy for treating type B aortic dissection with open aortoiliac replacement prior to thoracic endovascular aortic repair

“… 20 Conversely, others have reported that bare-metal stenting may offer positive remodeling in the distal aorta. 21 , 22 , 23 , 24 , 25 Concerns have also been raised that the PETTICOAT technique may jeopardize future adjunctive endovascular procedures because of stent strut interference. Other investigators have countered that a more expanded true lumen facilitates adjunctive procedures by virtue of the increase in workspace.…”
