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.

Background: Nonocclusive mesenteric ischemia (NOMI), a subtype of acute mesenteric ischemia, is primarily caused by mesenteric arterial vasoconstriction and decreased vascular resistance, leading to impaired intestinal perfusion.Commonly observed after cardiac surgery, NOMI affects older patients with cardiovascular or systemic diseases, accounting for 20-30% of acute mesenteric ischemia cases with a mortality rate of ∼50%. This review explores NOMI's pathophysiology, clinical implications in aortic dissection, and the unmet needs in diagnosis and management, emphasizing its prognostic significance.

The management of type B aortic dissection is one of the most challenging and debated topics in contemporary cardiovascular surgery practice. Patients with acute or chronic dissection-related complications, face high morbidity and mortality if not treated promptly. For most patients requiring intervention, thoracic endovascular aortic repair (TEVAR) is considered the gold standard.

Type B aortic dissection (TBAD) primarily affects men aged 60-65, with hypertension in over 80% of cases. The gold standard for the treatment of uncomplicated acute TBAD is Best Medical Therapy (BMT), which focused on controlling blood pressure and heart rate. However, Thoracic Endovascular Aortic Repair (TEVAR) has gained attention over the years, especially for complicated TBAD cases, by covering the primary entry tear, lowering false lumen pressure, and promoting aortic remodeling.

Preoperative identification of the Adamkiewicz artery (AKA) with adequate reconstruction or preservation during surgery is useful for protecting the spinal cord from ischemia during thoracoabdominal aortic repair. However, the identification of the AKA remains challenging in some cases, especially with chronic aortic dissection. In a 45-year-old man with chronic aortic dissection requiring thoracoabdominal aortic repair, conventional contrast-enhanced CT or MR angiography failed to detect AKA due to the large entry tear and an enlarged false lumen.

Trunk muscle decrease is reportedly associated with an increased risk of multiple adverse clinical outcomes. Acute aortic dissection (AAD) involves a systemic inflammatory response which is associated with exaggerated muscle protein catabolism. AAD requires prolonged hospitalization and potentially exacerbates muscle size decrease.
