Endovascular Management of Malperfusion Syndromes in Aortic Dissection.

Tech Vasc Interv Radiol 2021 Jun 23;24(2):100751. Epub 2021 Jul 23.

Department of Radiology, University of Michigan, Ann Arbor, MI.

Malperfusion Syndrome (MPS) refers to inadequate perfusion of end organs secondary to ongoing arterial obstruction of the aorta and its branches resulting in increased morbidity and mortality. While uncomplicated type B dissection can typically be monitored, type A or type B dissections with malperfusion syndrome are should be considered for hybrid treatment with an endovascular intervention.  In addition to pre-procedure CTA and labs, intra-procedure evaluation of the true lumen, false lumen, and branch vessels is performed with intravascular ultrasound (IVUS) and manometry to delineate static versus dynamic obstruction.

Differences in Aortic Diameter Measurements with Intravascular Ultrasound and Computed Tomography After Blunt Traumatic Aortic Injury.

Ann Vasc Surg 2018 Jul 23;50:148-153. Epub 2018 Feb 23.

Division of Vascular Surgery, University of California Davis, Sacramento, CA.

Background: Intravascular ultrasound (IVUS) has been recommended as an adjunct to thoracic endovascular aortic repair (TEVAR) as computed tomography (CT) in injured patients may inaccurately determine the true aortic diameter. We hypothesize that CT and IVUS offer discordant measurements of aortic diameter in trauma patients and that each modality may result in different graft size estimates for TEVAR.

Methods: Patients treated by TEVAR for blunt aortic injury from June 2011 to 2016 were reviewed. Read More

Sutureless Microsurgical Anastomosis Using an Optimized Thermoreversible Intravascular Poloxamer Stent.

Plast Reconstr Surg 2016 Feb;137(2):546-556

Stanford, Calif. From the Hagey Laboratory for Pediatric Regenerative Medicine, Division of Plastic and Reconstructive Surgery, Department of Surgery, Stanford University School of Medicine.

Background: Sutureless microvascular anastomosis has great translational potential to simplify microvascular surgery, shorten operative times, and improve clinical outcomes. The authors developed a transient thermoreversible microvascular stent using a poloxamer to maintain vessel lumen patency before application of commercially available adhesives to seal the anastomosis instead of sutures. Despite technical success, human application necessitates bovine serum albumin removal from existing formulations; rapid poloxamer transition between states; and increased stiffness for reliable, reproducible, and precise microvascular approximation.
