Thrombus and Calcium in Aortic Aneurysm Necks: Validation of a Scoring System in a Dutch Cohort Study

This study was conducted to validate a proposed classification system on the characteristics of the abdominal aortic aneurysm neck. The cohort comprised 100 consecutive patients who underwent open or endovascular aneurysm repair. Aneurysm neck characteristics of diameter, calcium, thrombus, and angulation were reviewed. The presence of calcium at the aortic aneurysm wall was associated with lower body mass index. Thrombus was found in 52% of the patients. Hypertension was correlated with the presence of aortic wall thrombus. At the renal artery level, angulation was anterior in 56%, right lateral in 39%, and left lateral in 27%. At the origin of the aneurysm, angulation was posterior in 76%, right lateral in 46%, and left lateral in 42%. A wide variety in these characteristics was found. A scoring system allows comparison of patient characteristics in studies describing the clinical outcome of endovascular aneurysm repair and should be included in study reports.

Repair of an isolated congenital left ventricular diverticulum.

Abstract  Left ventricular diverticulum is a rare congenital anomaly. We report two cases of isolated left ventricular diverticulum with a different clinical presentation. The first case was a nine‐year‐old boy with a history of congestive heart failure and ventricular arrhythmia. The second case was a 51‐year‐old asymptomatic male with abnormal electrocardiogram. Both patients had the diagnosis confirmed by cardiac magnetic resonance imaging and underwent successful surgical correction of the abnormality.

Ruptured Right Aortic Arch Aneurysm

A case of a ruptured right aortic arch aneurysm in a 74-year-old woman presenting with shock is reported. The diagnostic and operative findings are presented. We discuss the surgical approach and review the literature.

Spontaneous Rupture of the Left Subclavian Artery in Neurofibromatosis

Two patients with neurofibromatosis presented with expanding masses at the left supraclavicular region. Computed tomography (CT) scans revealed vascular masses. The patients underwent surgery and ruptures of the left subclavian artery were found. Both patients were treated by ligation of subclavian artery.

Computed Tomography of Aortic Intramural Hematoma and Thrombosed Dissection

A retrospective study was undertaken to evaluate the appearance of the aortic wall on computed tomography for the purpose of developing criteria for differentiating acute aortic intramural hematoma from thrombosed false lumen seen in aortic dissection. Computed tomography angiography findings of the thoracoabdominal aorta in 23 patients with suspected intramural hematoma and 25 with thrombosed false lumen were reviewed. The more common features of an intramural hematoma were hyperattenuation of the aortic wall, wall thickness less than a quarter of the aortic diameter, intrinsic wall calcification, a lesion extending around the entire aortic circumference, and ulcer-like projections that may be precursors of intramural hematoma. Wall thickness less than a quarter of the aortic diameter, lesion extending around the entire aortic circumference, and ulcer-like projections were the most useful indicators for distinguishing intramural hematoma from the thrombosed false lumen in aortic dissection.
