Angiotomography with multiplanar and threedimensional reconstruction
When thoracic and thoracoabdominal aortic pathology pushes the limits of currently available thoracic endovascular aortic repair (TEVAR) technology, we need to enhance our techniques to repair increasingly complex anatomy that, if treated by open surgery, is associated with significant morbidity and mortality. 1 Compromised distal landing zones have been implicated in late type Ib endoleaks.
Aortic Anatomy and Complications of the Proximal Sealing Zone after
In a series of CT scans of the aorta from 100 patients diagnosed with severe aortic stenosis planned for transcatheter aortic valve implantation, we measured the intravascular distance from the.

Aortic Landing Zones. In addition to the standard anatomic descriptors of the aortic anatomy, there is a more technical classification of aortic anatomy that is used to plan, guide, and report aortic interventions, especially endovascular stent-grafting.
Proximal landing zones for aortic arch and upper descending thoracic
Zone 2 continues from the celiac artery to the renal artery. Zone 3 extends from the origin of the lowest renal artery to the aortic bifurcation (infrarenal aorta). Zone 1 occlusion is utilized in patients in cardiac arrest or those in hemorrhagic shock with evidence of non-compressible hemorrhage arising below the diaphragm.
New Aortic Dissection Classification and Practical RealWorld
Of all injuries sustained in trauma, the aortic injury is one of the most time-sensitive, life-threatening conditions, second only to head injury as a cause of death. The morbidity and mortality associated with traumatic aortic injury are about 30% within the first 24 hours.
Aortic Dissection Explained Risk Factors, Symptoms, Diagnosis, FAQs
Aortic Valve Stenosis, Aortic Valve Regurgitation. Aortic valve diseases, including aortic valve stenosis (a narrowed valve opening) and aortic valve regurgitation (a leaking valve), require evaluation and management by a cardiologist or cardiac surgeon. More serious conditions may require surgery to repair or replace the aortic valve.

Aortic Anatomy and Complications of the Proximal Sealing Zone after
The aorta is divided into three zones (Figure 1). Proper placement of the REBOA catheter is in either Zone I or Zone III. Zone I is located just distal to the take-off of the left subclavian artery, and ends at the celiac trunk. Zone III is located just distal to the lowest renal artery and ends at the aortic bifurcation. Zone II is
Endovascular Today Expanding the Landing Zone for TEVAR (November 2016)
Zone 2: From the celiac trunk to the lowest renal artery Zone 2 is an unused zone because if of difficulty in occluding the bleeding vessel at this aortic location; Zone 3: From lowest renal artery to the aortic bifurcation; Indications. Non-compressible hemorrhage below the diaphragm in the abdomen, pelvis or retroperitoneum
The Aorta And Its Branches Steve Gallik
The aorta ( / eɪˈɔːrtə / ay-OR-tə; pl.: aortas or aortae) is the main and largest artery in the human body, originating from the left ventricle of the heart, branching upwards immediately after, and extending down to the abdomen, where it splits at the aortic bifurcation into two smaller arteries (the common iliac arteries ).
Proximal landing zones for aortic arch and upper descending thoracic
The aortic arch is a continuation of the ascending aorta and begins at the level of the second sternocostal joint. It arches superiorly, posteriorly and to the left before moving inferiorly. The aortic arch ends at the level of the T4 vertebra.
Society for Vascular Surgery (SVS) and Society of Thoracic Surgeons
Aortic regurgitation (AR) is the third most frequently encountered valve lesion and may be caused by abnormalities of the valve cusps or the aorta. Echocardiography is instrumental in the assessment of AR as it enables the delineation of valvular morphology, the mechanism of the lesion and the grading of severity. Severe AR has a major impact on the myocardium and carries a significant risk of.
Thoracic Endovascular Aortic Repair Anesthesiology Clinics
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an adjunct for controlling non-compressible truncal hemorrhage (NCTH) [].The REBOA concept defines three aortic zones (Fig. 1) in which aortic occlusion balloons (AOB) can be placed [].REBOA can be performed with or without fluoroscopic confirmation of the desired location, with zone III for junctional and pelvic bleeding.
Society for Vascular Surgery/Society of Thoracic Surgeons (SVS/STS
The aorta is divided into three separate zones for the purposes of REBOA (aortic length varies between individuals) Zone I of the aorta extends from the origin of the left subclavian artery to the coeliac artery (approx 20cm long in a young adult male) Zone II extends from the coeliac artery to the most caudal renal artery (approx 3cm long)
Reporting standards for endovascular aortic repair of aneurysms
Small volume aortic occlusion balloons (AOB) have poor occlusion rates in zone I (0-2.8%) and III (4.4-34.4%). Conclusions Men and older age groups have longer CLL distances to zone I and III and introduction depths of AOB must be adjusted.
