A 56-year-old man with a painful, progressively enlarging pulsatile mass in the bilateral popliteal fossae was diagnosed with a bilateral popliteal artery aneurysm (PAA) and referred to our hospital to undergo surgical therapy. Computed tomographic scanning demonstrated a large, middle-type PAA with a rich mural thrombus in the bilateral popliteal ...

Pediatric aneurysms are rare diseases distinct from classical adult aneurysms and therefore require different treatment strategies. Apart from saccular aneurysms that are more commonly found in older children, three major pathomechanisms may be encountered: trauma, infection, and dissection. The posterior circulation and more distal locations are more commonly encountered in ...

We investigate the flow dynamics and oscillatory behaviour of wall shear stress (WSS) vectors in intracranial aneurysms using high resolution numerical simulations. We analyse three representative patient-specific internal carotid arteries laden with aneurysms of different characteristics: (i) a wide-necked saccular aneurysm, (ii) a narrower-necked saccular aneurysm, and (iii) a case ...

We sought to determine whether differences exist in the factors associated with transient coronary artery (CA) dilation only compared to CA aneurysms after Kawasaki disease (KD). We reviewed all patients with KD assessed and treated at a single tertiary institution from January 1990 to April 2007. Of 1,374 patients (63% ...

Ophthalmic segment aneurysms account for about 5% of all intracranial aneurysms. Anatomical complexity of the paraclinoid region makes surgical management of aneurysms arising from the ophthalmic segment challenging. This study was carried out to assess the presenting features, complications and outcomes after surgical treatment of ophthalmic segment aneurysms. The authors ...

ATP acts as an extracellular signaling molecule in purinergic signaling that regulates vascular tone. ATP binds purinergic P2 nucleotide receptors on endothelial cells. Understanding the mass transport of ATP to endothelial cells by blood flow is thus important to predict functional changes in aneurysmal walls. While some clinical observations indicate ...

Intracranial aneurysms in the pediatric population are relatively rare entities. Immunocompromised patients (often from HIV/AIDS or pharmacological immunosuppression) represent a significant fraction of children with cerebral aneurysms. One proposed mechanism of aneurysm formation in these patients is from direct infection of the affected arteries. In this study, the authors report ...

OBJECTIVE: Because of their capability of secreting proteinases, macrophages play a central role in the growth and rupture of aneurysms. Noninvasive imaging of macrophages therefore may yield valuable information about the pathogenesis of aneurysm disease. We studied uptake of the macrophage-specific contrast agent ultrasmall paramagnetic iron oxide (USPIO) in the ...

Blood blister-like aneurysms are dangerous aneurysms with fragile walls arising from the supraclinoid internal carotid artery (ICA). Primary treatment of these aneurysms in the acute stage is challenging, due to the substantial risk of periprocedural bleeding. We describe a series of 4 patients who presented with ruptured blister-like aneurysm of ...

We present a case of a male patient diagnosed with a large inferior pancreaticoduodenal artery (IPDA) aneurysm, associated with a fresh thrombotic occlusion of the celiac trunk. Given the risk of splanchnic ischaemia, radiologic embolisation of the aneurysm combined with celiac axis stenting was deemed unsafe. Management was therefore modified ...

A 31-year-old woman with neurofibromatosis type I (NF-I) came to our hospital with hypotension and abdominal pain. A computed tomography (CT) scan showed blood in the retroperitoneum and two saccular aneurysms in the superior mesenteric artery (SMA). The largest measured 2.5 cm in diameter. She was treated with placement of ...
