Purpose: False lumen rupture in type B aortic dissection is a life-threatening and difficult-to-treat disease. Recently, case reports showcased endovascular therapy for false lumen rupture with the candy-plug technique, but residual retrograde flow was a problem. Therefore, we created a new false lumen occluder, the parachute-plug, with improved sealing and fixation, and reported the experience of using this technique. Case Report: Our patient was a 43-year-old man diagnosed with false lumen rupture of type B aortic dissection. After recovery from profound shock, he underwent axilla-axilla crossover bypass and thoracic endovascular aortic repair landing from aortic arch zone II to the proximal celiac trunk. Aortography confirmed entry sealing but revealed persistent retrograde flow through the reentry tear into the false lumen. The parachute-plug, with long sealing and little gutter formation, was deployed into the false lumen adjacent to the distal landing zone of the thoracic stent graft. Final aortography revealed no residual antegrade or retrograde blood flow. The patient was discharged 28 days after surgery. At the 2-year follow-up, computed tomography angiography showed complete thrombosis of the false lumen and shrinkage of the aneurysm. Conclusion: The parachute-plug may be useful for treating false lumen rupture in type B aortic dissection. Clinical Impact The advantages of the parachute plug are longer sealing, better fixation, less gutter and easy preparation. Therefore, we believe it will allow us to treat chronic type B dissecting aortic aneurysms with rupture more safely and reliably than ever before, effectively reducing false lumen-related bleeding and improving survival rate.

“…Since Ogawa described the candy-plug technique using modified Gore Excluder extender, other investigators have applied the method successfully in elective interventions (Wu et al, 2018 ; Kotani et al, 2017 ) and also in acute aortic ruptures (Lin et al, 2019 ; Morisaki et al, 2019 ). The prepared CP is advanced to the desired position with the delivery catheter of the endoprosthesis.…”

Purpose Aim of this technical note article is to introduce a modified, novel way to custom create a candy-plug (CP) device to endovascularly occlude false lumen. The technique is illustrated by a patient case with significant backflow to false lumen (FL). The patient had already undergone surgical repair of the ascending aorta, aortic arch and subsequent TEVAR procedure down to the ostium of the celiac trunk because of type A aortic dissection, but the descending thoracic aorta continued to dilate due to backflow to the FL from an uncovered tear at the level of the renal arteries. Materials and methods We modified a Gore Excluder 36–45 mm aortic extender (W. L. Gore & Associates, Inc. Flagstaff, USA) endoprosthesis into a CP device that was subsequently positioned under local anesthesia into the FL of the distal descending thoracic aorta. Results In 1 month control the backflow to false lumen had ceased and the aorta had decreased in diameter from 69 to 66 mm, FL from 37 to 34 mm, true lumen (TL) remained the same 32 mm. Conclusion We describe a modified, effective candy-plug technique to occlude retrograde false lumen filling in aortic dissection.
