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

Comparison of intravascular ultrasound- and centerline computed tomography-determined aortic diameters during thoracic endovascular aortic repair.

J Vasc Surg 2017 10 22;66(4):1184-1191. Epub 2017 Jun 22.

Comprehensive Aortic Center, Keck School of Medicine, University of Southern California, Los Angeles, Calif.

Background: Accurate sizing of stent grafts during thoracic endovascular aortic repair (TEVAR) is critical for a successful outcome. Centerline measurements using three-dimensional reconstruction of preoperative computed tomography angiography (CTA) is the current standard for stent graft sizing. However, this technique is predicated on an idealized straightened aorta and does not account for the variability in the aortic diameter during the cardiac cycle or the overall status of the patient's volume.

Sutureless Microsurgical Anastomosis Using an Optimized Thermoreversible Intravascular Poloxamer Stent.

Plast Reconstr Surg 2016 Feb;137(2):546-56

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.

Radiologia Interventistica, Azienda Ospedaliera Universitaria Senese, Policlinico Santa Maria alle Scotte, viale Bracci 16, 53100 Siena, Italy.

An innovative approach, the JAG tearing technique, was performed during thoracic endovascular aneurysm repair in a patient with previous surgical replacement of the ascending aorta with a residual uncomplicated type B aortic dissection who developed an aneurysm of the descending thoracic aorta with its lumen divided in two parts by an intimal flap. The proximal landing zone was suitable to place a thoracic stent graft. The distal landing zone was created by cutting the intimal flap in the distal third of the descending thoracic aorta with a radiofrequency guide wire and intravascular ultrasound catheter. Read More

[Hybrid repair of thoracoabdominal aortic aneurysm in high-risk patients using a quadrifurcated graft].

Kyobu Geka 2011 Jan;64(1):51-5

Department of Cardiovascular Surgery, Osaka City University Graduate School of Medicine, Osaka, Japan.

Surgical treatment for thoracoabdominal aortic aneurysm is still challenging and is associated with a high risk of paraplegia. Hybrid repair with stent graft insertion for the thoracoabdominal aorta excluding the branches of the lumbar and visceral arteries and bypass grafting to the visceral branches has been introduced as a less invasive treatment that reduces the risk of paraplegia. For hybrid repair, it is important to have appropriate management of the revascularized grafts to the 4 visceral arteries with sufficient inflow. Read More

University of South Florida Health Science Center, Graduate Medical Education, Tampa, FL, USA.

Primary malignant tumors of the aorta (PMTAs) are an extremely rare clinical entity. In most cases, the diagnosis is made either postmortem or late in the course of disease due to a low index of clinical suspicion and presenting symptoms that mimic far more common athero-embolic processes. Due to the intravascular origin of these tumors, peripheral and mesenteric embolic events represent a major source of morbidity and mortality. Read More

A right-sided aortic arch with an aberrant left subclavian artery is a congenital vascular anomaly that is easily detectable in utero at the level of the three vessels and trachea view, but which is rarely symptomatic in the neonate. We present a newborn with prenatally diagnosed right-sided aortic arch and aberrant subclavian artery who showed a clinically relevant stenosis of the subclavian artery during the first week of life. An intravascular stent was implanted into the stenosis of the aberrant left subclavian artery by catheterization. Read More

Blood coagulation and fibrinolytic response after endovascular stent grafting of thoracic aorta.

J Vasc Surg 2003 Jun;37(6):1213-8

Department of Surgery II, Tokyo Medical University, Tokyo, Japan.

Objective: Thrombosis is common in aneurysms immediately after stent-grafting, because of exclusion from systemic blood flow. We studied changes in blood coagulation and the fibrinolytic system in patients with thoracic aortic aneurysm or dissection after stent-grafting to examine risk for consumption coagulopathy.

Methods: Thirty-one thoracic aortic aneurysms were treated with stent-grafting (aneurysm group), and 29 aortic dissections were treated with entry closure with stent-grafting (dissection group). Read More

Spontaneous and isolated dissection of the external iliac artery: a case report.

Ann Thorac Cardiovasc Surg 2002 Jun;8(3):180-2

Department of Thoracic Surgery, Hiroshima Prefecture Hospital, Hiroshima, Japan.

Spontaneous and isolated dissection of the limb arteries without involvement of the aorta is extremely rare. We present a 36-year-old male who has 95% tapering stenosis and dissection of the left external iliac artery with abrupt onset with total thrombosis in the false lumen until the level of the inguinal ligament. We also suggest that endovascular stent graft placement is a useful treatment for isolated arterial dissections prior to operation in consideration of the technical ease and safety of guiding intravascular ultrasound like in this case.

Endoluminal stent graft repair for acute and chronic type B aortic dissection and atherosclerotic aneurysm of the thoracic aorta: an interdisciplinary task.

Eur J Cardiothorac Surg 2002 Dec;22(6):891-7

Department of Thoracic and Cardiovascular Surgery, University of Essen, 45147 Essen, Germany.

Objective: Endoluminal thoracic aortic stenting is a new therapeutic tool in reducing the operative trauma of the patient. However, the inherent risks of aortic stent grafting are perivascular leakage, stent dislocation, blunt rupture of the aorta, side branch occlusion and neurological sequelae. To reduce these risks, in our institution all stent implantations were performed in close collaboration with our fellow cardiologists under biplane X-ray control supported by simultaneous intravascular and transoesophageal ultrasound imaging.

Balloon dilation and stent implant through the side of a previously placed intravascular stent: a new option for the interventionalist.

Catheter Cardiovasc Interv 2002 Jul;56(3):387-93

Lillie Frank Abercrombie Section of Pediatric Cardiology, Department of Pediatrics, Baylor College of Medicine and Texas Children's Hospital, Houston, Texas 77030, USA.

Intravascular stent placement for relief of vascular stenoses often requires that a stent be positioned across the origin of side-branch vessels. Most currently available peripheral vascular stents have a closed-cell design that will not allow catheter manipulation, dilation, or stenting through the stent cells. Therefore, if a side branch arising off a previously stented vessel is stenotic or if its origin has been compromised, transcatheter dilation of the branch vessel has not been possible. Read More

Aortic dissection after angioplasty and stenting of an aortic coarctation: detection by intravascular ultrasonography but not transesophageal echocardiography.

J Am Soc Echocardiogr 2001 Jan;14(1):73-6

Department of Anesthesiology, The Heart Center, Duke University Medical Center, Durham, NC 27710, USA.

In this case report, an iatrogenic dissection of the descending aorta occurred during balloon angioplasty and stenting of a recurrent coarctation. The dissection was not seen by transesophageal echocardiography, but intravascular ultrasonography, performed routinely during such procedures at this institution, identified the dissection and guided further therapeutic stent placement.

Endovascular approaches for traumatic arterial lesions.

Semin Vasc Surg 1997 Dec;10(4):272-85

Department of Surgery, Montefiore Medical Center, University Hospital, Albert Einstein College of Medicine, New York, NY 10467, USA.

Vascular injuries caused by blunt or penetrating trauma can be challenging to diagnose and treat, particularly when they involve central vessels. Endovascular treatment for vascular trauma includes the placement of embolization coils and intravascular stents and the employment of stented grafts. The use of stented grafts appears to be associated with decreased blood loss, a less invasive insertion procedure, reduced requirements for anesthesia, and a limited need for an extensive dissection in a traumatized field.
