BACKGROUND A post-irradiated carotid pseudoaneurysm at the skull base can cause life-threatening blowout syndrome. Conventional treatments include parent vessel occlusion, endovascular coiling or covered stenting. Use of the Pipeline embolization device (PED) for pseudoaneurysm exclusion at the skull base is not well described. OBJECTIVE To report the clinical and angiographic outcome after u...

Purpose: To report the surgical outcome of traumatic blow out fractures of the floor of the orbit. Materials and methods: Five patients who sustained orbital floor blowout fracture following trauma underwent surgical repair via trans-conjunctival or subciliary approaches. One patient had sustained bilateral blowout fracture. Three patients presented with symptoms early following the fracture wi...

Twenty-five cases of blowout fracture were treated at Yamaguchi University hospital between 1981 and 1984. Eighteen cases were male and seven cases were female. Chief complaints and major symptoms were diplopia, disturbance in eyeball movement and disturbance of vison. Sinus-x-ray examination by occipito-frontal view, Waters' view and occipito-frontal polytomography were recommended for precise...

In this paper the method of critical curves, a tool for the study of the global dynamical properties of two-dimensional noninvertible maps, is applied to the study of chaos synchronization and related phenomena of riddling, blowout, and on-off intermittency. A general procedure is suggested in order to obtain the boundary of a particular two-dimensional compact trapping region, called absorbing...

Abstract Visualization of multi-phase jets and plumes is a relatively new subject. Discussions on how to visualize them have not been seen elsewhere. Multi-phase jets and plumes (e.g. a plume from a deep water blowout that consist of a mixture of oil, gas, and gas hydrates) undergo phase changes during the transport of fluids up the water column. Effectively visualizing all the pertinent jet or...

A simplified method is used to determine the optimum water content in the flue gases of charcoal gasifiers to be utilized as alternative fuels in the operation of engines and gas turbines for power generation. Computational models of plug flow reactors and well stirred reactors are employed to simulate the reaction and post-flame zones, adopting different chemical mechanisms. In the simulations...

Background Lower eyelid incisions are widely used for the orbital approach in periorbital trauma and aesthetic surgery. In general, the subciliary approach is known to cause disposition of the lower eyelid by scarring the anterior lamella in some cases. On the other hand, many surgeons believe that a transconjunctival approach usually does not result in such complications and is a reliable meth...

Treatment of aortic prosthetic graft infections remains a challenge. One frequently encountered technical difficulty when removing an infected prosthetic aortic graft is how to close a short, friable remnant aortic stump. We present three case reports in which we used a layer of posterior rectus fascia-peritoneum to bolster oversewing a short infected aortic stump after removal of an infected a...

PURPOSE Carotid blowout syndrome due to rupture of internal carotid artery pseudoaneurysm in NPC patients with prior neck radiation is an uncommon but life-threatening complication. Concomitant carotid stenosis with ischemic stroke and carotid rupture from pseudoaneurysm is rare. CASE REPORT A 71-year-old man had a history of NPC treated with radiation therapy 26 years ago. He was admitted to...

Measuring the ocular blood flow in neonates may clarify the relationships between eye diseases and ocular circulation abnormalities. However, no method for noninvasively measuring ocular circulation in neonates is established. We used laser speckle flowgraphy (LSFG) modified for neonates to measure their ocular circulation and investigated whether this method is reproducible. During their norma...
