Subjective Image Quality

To evaluate the impact of a novel, deep-learning-based image reconstruction (DLIR) algorithm on image quality in CT angiography of the aorta, we retrospectively analyzed 51 consecutive patients who underwent ECG-gated chest CT angiography and non-gated acquisition for the abdomen on a 256-dectector-row CT. Images were reconstructed with adaptive statistical iterative reconstruction (ASIR-V) and DLIR. Intravascular image noise, the signal-to-noise ratio (SNR) and the contrast-to-noise ratio (CNR) were quantified for the ascending aorta, the descending thoracic aorta, the abdominal aorta and the iliac arteries. Two readers scored subjective image quality on a five-point scale. Compared to ASIR-V, DLIR reduced the median image noise by 51-54% for the ascending aorta and the descending thoracic aorta. Correspondingly, median CNR roughly doubled for the ascending aorta and descending thoracic aorta. There was a 38% reduction in image noise for the abdominal aorta and the iliac arteries, with a corresponding improvement in CNR. Median subjective image quality improved from good to excellent at all anatomical levels. In CT angiography of the aorta, DLIR substantially improved objective and subjective image quality beyond what can be achieved by state-of-the-art iterative reconstruction. This can pave the way for further radiation or contrast dose reductions.

All Cause Mortality

The aim of this study was to evaluate all-cause mortality and aortic reoperations after surgery for Stanford type A aortic dissection (TAAD). We evaluated the late outcome of patients who underwent surgery for acute TAAD from January 2005 to December 2017 at the Helsinki University Hospital, Finland. We studied 309 patients (DeBakey type I TAAD: 89.3%) who underwent repair of TAAD. Aortic root repair was performed in 94 patients (30.4%), hemiarch repair in 264 patients (85.4%) and partial/total aortic arch repair in 32 patients (10.4%). Hospital mortality was 13.6%. At 10 years, all-cause mortality was 34.9%, and the cumulative incidence of aortic reoperation or late aortic-related death was 15.6%, of any aortic reoperation 14.6%, reoperation on the aortic root 6.6%, on the aortic arch, descending thoracic and/or abdominal aorta 8.7%, on the descending thoracic and/or abdominal aorta 6.4%, and on the abdominal aorta 3.8%. At 10 years, cumulative incidence of reoperation on the distal aorta was higher in patients with a diameter of the descending thoracic aorta ≥35 mm at primary surgery (cumulative incidence in the overall series: 13.2% vs. 4.0%, SHR 3.993, 95%CI 1.316–12.120; DeBakey type I aortic dissection: 13.6% vs. 4.5%, SHR 3.610, 95%CI 1.193–10.913; patients with dissected descending thoracic aorta: 15.8% vs. 5.9%, SHR 3.211, 95%CI 1.067–9.664). In conclusion, surgical repair of TAAD limited to the aortic segments involved by the intimal tear was associated with favorable survival and a low rate of aortic reoperations. However, patients with enlarged descending thoracic aorta at primary surgery had higher risk of late reoperation. Half of the distal aortic reinterventions were performed on the abdominal aorta.

Middle Aortic Syndrome

The middle aortic syndrome (MAS) is rare (about 0.5-2% of all the cases of aortic coarctation) vascular disorder characterized by severe narrowing in the descending thoracic aorta, abdominal aorta, or both. It can be congenital or acquired due to several conditions.MAS may present clinically as uncontrolled hypertension, abdominal angina or lower limb claudication. Surgical treatment is effective in controlling symptom and improves life expectancy. Cardiovascular Journal Volume 6, No. 1, 2013, Page 60-62 DOI: http://dx.doi.org/10.3329/cardio.v6i1.16117

Late Manifestation

Rupture of the descending aorta following deceleration trauma is a catastrophic event because it has a high mortality. Prompt surgical treatment is generally considered to be mandatory. However, a few injured patients may leave the hospital with an undiagnosed aortic rupture which may give rise to a chronic pseudoaneurysm. In this report, a 28-year-old man is presented in whom a pseudoaneurysm of the descending thoracic aortic was diagnosed six months after a car accident.

We compared clinical and angiographic features of nonspecific aorto-arteritis in children with those of adult patients. Digital subtraction angiography by i.v. and/or i.a. injection was carried out in 104 patients. In group 1, consisting of 32 patients aged 16 years and younger, hypertension (75%) was the most common clinical feature, followed by diminished pulse, bruit (72% each), congestive cardiac failure (38%), and limb claudication (13%). Obstructing arterial lesions were always present and commonly involved the abdominal aorta (75%), descending thoracic aorta (41%), renal (63%) and subclavian (41%)) arteries. In Group 2, consisting of 72 patients more than 16 years of age, arterial bruit (91%), and diminished pulse (82%) were the most common symptoms. Hypertension occurred in 61%, congestive failure in 14%, and limb claudication in 30%. Obstructing lesions were always seen and commonly involved the abdominal aorta (77%) and renal arteries (64%). Involvement of the descending thoracic aorta (26%) was less common but subclavian (57%) and carotid (24%) arteries were more commonly involved than in group 1. Arterial aneurysms and pulmonary involvement were uncommon in both groups. There were some clinical and angiographic differences in nonspecific aorto-arteritis between children and adults but these were statistically insignificant (chi-square test).
