Reflection from UK Aortic Group: Frozen Elephant Trunk Technique as Optimal Solution in Type A Acute Aortic Dissection.

Summary of "Reflection from UK Aortic Group: Frozen Elephant Trunk Technique as Optimal Solution in Type A Acute Aortic Dissection."

Diseases of the thoracic aorta are increasing in prevalence worldwide. Recent data indicated wide regional variation in the volume and complexity of aortic cases undertaken in United Kingdom cardiac centers, especially in case of for type A acute aortic dissection (ATAAD) conditions. Patients treated in high-volume centers with a specific multidisciplinary aortic program had a significant reduction in ATAAD mortality when compared with low-volume centers. Following the initial phase of a national aortic center reorganisation, the current study reflects the initial experience of a national collective of cardiothoracic surgeons with expertise in complex aortic surgery, using frozen elephant trunk as standard technique for the surgical treatment of patients affected by ATAAD. Between June 2013 and October 2017, 66 ATAAD patients (45% women) underwent hybrid aortic arch and frozen elephant trunk repair with the Thoraflex Hybrid graft at 8 UK high-volume aortic centers. The in-hospital mortality accounted for 8 (12%) patients. Postoperative temporary or permanent neurological events and temporary renal replacement therapy occurred in 17% and 20% of patients, respectively. No spinal cord injury events were documented. Our data were similar to those reported in literature in the two largest experiences with the use of FET in ATAAD condition (in-hospital/30-day mortality: 11 to 12%). This initial experience demonstrated that FET can potentially be adopted as standard approach in life-threatening aortic diseases, with acceptable complication and mortality rates.

Medical and Biotech [MESH] Definitions

Small clusters of chemoreceptive and supporting cells located near the ARCH OF THE AORTA; the PULMONARY ARTERIES; and the coronary arteries. The aortic bodies sense PH; CARBON DIOXIDE; and oxygen concentrations in the BLOOD and participate in the control of RESPIRATION. The aortic bodies should not be confused with the PARA-AORTIC BODIES in the abdomen (which are sometimes also called aortic bodies).

The first and largest artery branching from the aortic arch. It distributes blood to the right side of the head and neck and to the right arm.

Small masses of chromaffin cells found near the SYMPATHETIC GANGLIA along the ABDOMINAL AORTA, beginning cranial to the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) or renal arteries and extending to the level of the aortic bifurcation or just beyond. They are also called the organs of Zuckerkandl and sometimes called aortic bodies (not to be confused with AORTIC BODIES in the THORAX). The para-aortic bodies are the dominant source of CATECHOLAMINES in the FETUS and normally regress after BIRTH.

Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).

Thinly cut sections of frozen tissue specimens prepared with a cryostat or freezing microtome.
