Thrombus in the thoracic aorta not related to aneurysm or atherosclerosis is a rare clinical entity with a limited number of cases reported. Floating thrombus is defined as non-adherent part of the thrombus floating within the aortic lumen. Herein, we present a 48-year-old woman who presented with progressive midline dull, aching abdominal pain of 2-day duration. Thoracoabdominal computed tomography revealed a free floating thrombus extending from the aortic arch into the superior mesenteric artery. Transesophageal echocardiography confirmed the findings of a thrombus extending through the aortic arch...

BACKGROUND: Anatomical variations of the middle cerebral artery (MCA) are an important clinical issue, due to high prevalence of intracranial aneurysms. Anatomical variations of vessels can lead to higher shear stress, which is thought to be the main factor leading to aneurysm formation and consequently to higher prevalence of aneurysms. The aim of this study was to evaluate anatomy of the MCA; to classify MCA aneurysms using CT angiography and to correlate anatomical variations of MCA and circle of Willis with prevalence of MCA aneurysms...

Current cardiovascular ultrasound mainly employs planar imaging techniques to assess function and physiology. These techniques rely on geometric assumptions, which are dependent on the imaging plane, susceptible to inter-observer variability, and may be inaccurate when studying complex diseases. Here, we developed a gated volumetric murine ultrasound technique to visualize cardiovascular motion with high spatiotemporal resolution and directly evaluate cardiovascular health. Cardiac and respiratory-gated cine loops, acquired at 1000 frames-per-second from sequential positions, were temporally registered to generate a four-dimensional (4D) dataset...

Background: Visceral arterial pseudoaneurysms (VAPAs) are rare vascular entities with serious consequences. Traditionally, they are associated with trauma, infection, and inflammatory disease, or they can arise as a post-operative complication. Report: An 87 year old man presented with abdominal pain and was found to have a spontaneous VAPA on a computed tomography angiogram. Serial imaging 4 months previously had demonstrated no aneurysm. Between scans, warfarin was changed to apixaban for aortic valve replacement, but he had no other changes to any other medications...

Background: Mycotic aortic aneurysms are rare and life-threatening. Unfortunately, no established guidelines exist for the treatment of patients with mycotic aortic aneurysms. The purpose of this study was to evaluate the midterm outcomes of the open repair of mycotic thoracic and thoracoabdominal aneurysms and suggest a therapeutic strategy. Methods: From 2006 to 2016, 19 patients underwent open repair for an aortic aneurysm. All infected tissue was extensively debrided and covered with soft tissue...

REVIEW
Tetsuo Horimatsu, Ha Won Kim, Neal L Weintraub
Perivascular adipose tissue (PVAT) surrounds most large blood vessels and plays an important role in vascular homeostasis. PVAT releases various chemokines and adipocytokines, functioning in an endocrine and paracrine manner to regulate vascular signaling and inflammation. Mounting evidence suggests that PVAT plays an important role in atherosclerosis and hypertension; however, the role of PVAT in non-atherosclerotic vascular diseases, including neointimal formation, aortic aneurysm, arterial stiffness and vasculitis, has received far less attention...

BACKGROUND: The study aims to report outcomes of open repair (OR) and endovascular aneurysm repair (EVAR) in octogenarians. METHODS: Consecutive patients aged between 80 and 89 who underwent OR or EVAR were identified from a prospectively collected departmental database. Short-term outcomes included 30 days mortalities and perioperative complications; long-term outcomes included overall survival and re-intervention using the Kaplan-Meier method. Logistic regression was used to identify predictors for operative mortality and Cox regression analysis was used to identify predictors for long-term survival...

We describe the case of a 69-year-old man with a thoracic pseudoaneurysm caused by a diffuse large B-cell lymphoma. He had a large mass inside the aortic arch. Five weeks later, an asymptomatic aneurysm protruding from the minor curvature of the distal aortic arch was observed. We suspected a mycotic pseudoaneurysm and performed total arch replacement with an omental pedicle flap graft. Intraoperative tissue cultures and histopathologic tests identified no bacteria, however. Eventually, a pathologic examination revealed that the structure initially suspected to be an intramural thrombus was a diffuse large B-cell lymphoma...

Coronary artery fistulae and coronary aneurysms are rare anomalies. When they become symptomatic, they require precise anatomic information to allow for planning of the therapeutic procedure. We report a case in which both fistulae and aneurysm were present. The required information could only be obtained by electrocardiogram-gated computed tomography with reformation. This imaging modality should be considered in every case of fistula or coronary aneurysm.

Takayasu arteritis is an idiopathic chronic granulomatous panarteritis predominantly affecting the aorta and its main branches. Although idiopathic, genetic contribution to disease susceptibility is being increasingly recognised. Rare in children, Takayasu arteritis is a worldwide disease with significant morbidity and mortality. Its diagnosis is a challenge and requires awareness of the condition as clinical features at presentation are non-specific and assessing disease activity is difficult. In the inflammatory stage, treatment is essential to prevent the insidious course and vascular damage: stenotic, occlusive lesions, aneurysms, and aortic regurgitation...
