OBJECTIVES: Bicuspid aortic valve (BAV) is the most common congenital valvular abnormality and frequently presents with accelerated calcific aortic valve disease, requiring aortic valve replacement (AVR) and thoracic aortic aneurysm and dissection. Supporting evidence for Association Guidelines of aortic dimensions for aortic resection is sparse. We sought to determine whether concurrent repair of dilated or aneurysmal aortic disease during AVR in patients with BAV substantially improves morbidity and mortality outcomes...

Herein, we report a rare case of type B aortic dissection that occurred after endovascular aortic aneurysm repair (EVAR). A 66-year-old man underwent successful EVAR for an abdominal aortic aneurysm (AAA). Computed tomography (CT) 2 years after EVAR showed a type B aortic dissection with stent-graft migration and AAA expansion. Juxtarenal aortic expansion precluded simple stent-graft placement. He underwent hepato-spleno-renal bypass followed by stent-graft placement just below the superior mesenteric artery...

A 73-year-old woman had undergone hemiarch replacement with primary entry resection for treating acute type A dissection 6 years ago. Postoperative computed tomography (CT) showed a patent false lumen (FL) in the aortic arch and a reentry tear in the right subclavian artery. The remaining aortic arch enlarged, which resulted in formation of a 55-mm-diameter aneurysm. We performed reentry occlusion using embolization with glue and coil. The patient's clinical course after the procedure was uneventful, and subsequent CT showed that FL was thrombosed and had decreased in size...

In this study, the case of a 46-year-old female patient with localized aortic root dissection and a superior mesenteric artery (SMA) aneurysm is described. Computed tomographic angiography could not clearly delineate an intimal flap in the aortic root, but it detected SMA aneurysm, which implied the presence of a vulnerability of the aortic wall. Finally, transesophageal echocardiography (TEE) evidently showed the intimal flap localized in the aortic root. The present case suggests that TEE is of paramount importance for detecting localized aortic root dissection...

During aneurysm clipping, ischemic complications may occur and require a rescue treatment, usually surgical. We present two such cases that required urgent rescue treatment, performed through an endovascular route. Our first case presented with a non-ruptured right posterior inferior cerebellar artery (PICA) aneurysm. After permanent clip positioning, occlusion of the PICA occurred. An unsuccessful attempt of clip repositioning was performed. We therefore positioned a stent obtaining complete flow restoration...

OBJECTIVE: Isolated spontaneous dissection of the superior mesenteric artery (SMA) and celiac artery (CA) remains a rare condition; however, it has been increasingly noted incidentally on diagnostic imaging. The purpose of this study was to examine the natural history and outcomes of patients presenting with isolated spontaneous mesenteric artery dissection (SMAD). We hypothesized that most SMADs can be treated nonoperatively. METHODS: This was a single-center retrospective review of patients presenting with the diagnosis of SMAD between 2006 and 2016...

BACKGROUND: To reduce complications associated with conventional pterional craniotomy, a transsylvian keyhole approach for unruptured small anterior circulation aneurysms is proposed. METHODS: A 7-cm linear scalp incision is made along the hairline, beginning at the zygoma, followed by minimal temporal muscle dissection. Two burr holes are drilled out at McCarty's point and the temporal bone, and a 3-cm equilateral triangle bone flap is made, whose apex is located above the sylvian point...

A 13-year-old boy with a spontaneous vertebrobasilar artery dissecting aneurysm (VADA) in the extracranial artery, which was only 1 mm away from the initial segment of subclavian artery, was successfully treated with a covered-stent to block the artery of the VADA. Our experience indicates that this is a fast, reliable, effective and economical technique, particularly suitable for surgeries in settings with limited resources.

Thoracic aortic aneurysm is a common and lethal disease that requires regular imaging surveillance to determine timing of surgical repair and prevent major complications such as rupture. Current cross-sectional imaging surveillance techniques, largely based on computed tomography angiography, are focused on measurement of maximal aortic diameter, although this approach is limited to fixed anatomic positions and is prone to significant measurement error. Here we present preliminary results showing the feasibility of a novel technique for assessing change in aortic dimensions, termed vascular deformation mapping (VDM)...

Nontraumatic hemopericardium is a potentially fatal pathology that is most commonly caused by myocardial wall rupture, ruptured aortic dissection, aortic aneurysm rupture, or a neoplastic process. A rare potential cause of hemopericardium is pulmonary artery dissection, with less than 100 reported cases in the literature. Pulmonary artery dissection is associated with pulmonary artery aneurysm, pulmonary artery hypertension, and congenital heart disease. We report a fatal case of nontraumatic hemopericardium caused by a ruptured dissecting pulmonary artery aneurysm in a 16-year-old girl with patent ductus arteriosus...

Introduction: Balloon angioplasty can be a requisite approach for the treatment of symptomatic and/or severe vasospasm. Dual-lumen microcatheter balloons have multiple potential advantages for this indication including accommodating a 0.014-inch wire and the potential to deliver superselective vasodilators directly via the microcatheter prior to angioplasty. Methods: The authors reviewed a 3-year institutional experience with the Scepter XC balloon (Microvention, Tustin, CA, USA) in the treatment of postaneurysmal subarachnoid hemorrhage vasospasm, focusing on treatment methods, angiographic, and clinical results...

BACKGROUND: Posterior cerebral artery aneurysms are uncommon, with an occurrence rate of less than 1% of intracranial aneurysms. They have various shapes, including saccular and fusiform. Dissecting aneurysms may occur in distal posterior cerebral artery and they may affect the whole artery. Endovascular therapy is considered as a safe method of treatment and there are different techniques for endovascular therapy. SUMMARY: Posterior cerebral artery aneurysms are uncommon...

Low-profile stents seem to be associated with a higher incidence of thromboembolic events compared with preexisting stents. We conducted a systematic review of 11 eligible reports and a meta-analysis of 7 reports with respect to the clinical efficacy and safety of low-profile stents. There were 217 intracranial aneurysms reported; 22% were ruptured aneurysms. In all, 72% were treated using single stenting, 19% were treated using overlapping stenting, and 6% were treated using balloon angioplasty followed by stenting; 3% were used to assess the flow diverter effect in a dissecting aneurysm or were treated using unexpected subtotal coil packing...

The embryonic lineage of intramural cells, microstructural organization of the extracellular matrix, local luminal and wall geometry, and haemodynamic loads vary along the length of the aorta. Yet, it remains unclear why certain diseases manifest differentially along the aorta. Toward this end, myriad animal models provide insight into diverse disease conditions-including fibrosis, aneurysm and dissection-but inherent differences across models impede general interpretations. We examined region-specific cellular, matrix, and biomechanical changes in a single experimental model of hypertension and atherosclerosis, which commonly coexist...
