Subintimal recanalization is beneficial in selected patients with peripheral chronic total occlusions (CTO). However, in complex cases, re‐entry into the true arterial lumen may prove to be unsuccessful with a conventional guidewire or a re‐entry catheter when using standard femoral artery access. Our case series describes these technical dilemmas along with strategies that can be utilized to overcome these challenges. © 2011 Wiley‐Liss, Inc. 相似文献

Pharmacomechanical thrombolysis (PMT) is an emerging treatment option for symptomatic deep vein thrombosis (DVT). This may obviate the need for systemic or catheter-directed thrombolysis. PubMed, EMBASE, and Cochrane database search of PMT in acute and chronic symptomatic DVT was undertaken. Baseline demographic and clinical characteristics, procedural details, DVT characteristics, and procedural and clinical outcomes are presented. A total of 8 case series (n = 2528; 1998-2009) qualified for inclusion. Lower extremity symptomatic DVTs constituted the majority of the cases (>80%). Both acute (<14 days) and chronic (>14 days) DVTs were included. Procedural success was 59% to 100% and catheter-directed thrombolysis was used as an adjunct in 16% to 53%. No deaths or major bleeding complications were reported. Pharmacomechanical thrombolysis leads to the immediate resolution of clinical symptoms of DVT in the majority of patients. Pharmacomechanical thrombolysis may be a safe and novel method, when appropriate expertise and resources are available, for the treatment of symptomatic acute and chronic DVT. 相似文献

Calcifying epithelial odontogenic tumor (CEOT) is a rare benign, but locally infiltrating odontogenic neoplasm. It accounts for less than 1% of all odontogenic tumors. This is a case report of recurrent CEOT in the maxilla. A 35-year-old patient reported after three years of surgical excision of the lesion, with a recurrence. It is of particular concern because of its anatomic location in the maxilla. Maxillary tumors tend to be more aggressive and rapidly spreading and may involve the surrounding vital structures. Adequate resection of the lesion with disease-free surgical margins and long-term follow-up is recommended. 相似文献

A 33-year-old patient with a huge aneurysmal bone cyst (ABC) was imaged using cone-beam CT, MRI, and angiography. ABC is an uncommon non-neoplastic, expansile lesion of bone. Although common in the appendicular skeleton and spine, only 2% of the lesions occur in the craniofacial skeleton. The plain radiographic features of gnathic ABC may show an omni-expansile unilocular or multilocular radiolucency. Fluid-fluid levels have been reported in cystic compartments of ABCs; however, this feature is not diagnostically specific for ABC. In this article, we present a case of a rapidly growing, extraordinarily large ABC of the posterior mandible, with emphasis on comparative imaging features of this lesion in cone-beam CT, MRI, and carotid angiography. 相似文献

Two-component organogels offer several advantages over one-component gels, but their design is highly challenging. Hence, it is extremely important to design new approaches for the crafting of two-component organogels with interesting optical and mechanical properties. Herein, we report the design of a new class of two-component supergelators obtained from the assembly between acid functionalized tetraphenylethylene (TPE)-based dendrons and alkylated melamine. No gelation behaviour is observed for the individual components, but interestingly, remarkable gelation behaviour is observed for their hydrogen-bonded complex. The primary driving force responsible for the gelation is the strong π–π stacking interaction of TPE units. Because of the strong π-stacking of TPEs in the gel state, the C(sp2)–C(sp2) bond rotation of the TPE segment is completely arrested in the gel state, which results in intense fluorescence emission of the gels. Furthermore, excellent elastic response is observed for the gels as evident from their high storage modulus compared to loss modulus values. Our results clearly demonstrate that by the appropriate selection of the molecular components, this approach can be applied for the creation of functional nanomaterials with emergent properties absent in the individual blocks.Design of a novel class of two-component, highly emissive, low molecular weight supergelator is reported. 相似文献

We report the first case of coil embolization using the “modified neck remodeling technique” in the management of a splenic artery aneurysm. This technique was feasible due to the unique and complex anatomy of the aneurysm. This condition has been largely treated by vascular surgeons and interventional radiologists; however, this patient was referred to the interventional cardiologists for endovascular coiling. © 2010 Wiley‐Liss, Inc. 相似文献

Previous studies have shown that acute stress stimulates colonic motor function via a central corticotropin releasing factor (CRF) in rodents. However, little is known whether colonic motility is altered following chronic stress. We studied the changes of colonic motor function in response to chronic stress or daily administration of CRF in rats. Rats were subjected to restraint stress for 90 min for 5 consecutive days (chronic stress). Another group of rats received intracisternal (IC)-injection of CRF (1 μg) for 5 consecutive days. At the 1st day of restraint stress, calculated motility index was significantly increased by over 200% of basal in the proximal and distal colon. Similar results were obtained in response to the 2nd and 3rd day of restraint stress. In contrast, at the 5th day, restraint stress caused no more significant increase of colonic motility. Similarly, accelerated colonic transit induced by acute stress was no more observed following chronic stress. Increased, colonic motility and accelerated colonic transit induced by CRF were not attenuated at the 5th day. It is suggested that adaptation mechanism is developed following chronic stress. The decrease in colonic motor function in chronic stress is not due to reduced sensitivity to central CRF. 相似文献

An unusual case of paroxysmal kinesigenic dyskinesia. 总被引:2,自引:0,他引:2
Paroxysmal kinesigenic dyskinesia (PKD) is an uncommon neurological disorder characterised by abnormal episodic brief movements induced by sudden movements of the body. The recognition and understanding of this disorder has increased over the past few decades. While most cases are idiopathic, the association of PKD with various disorders, including metabolic abnormalities has also been reported. We report an interesting case of a 52 year old male who presented with PKD manifesting as subtle facio-brachial movements and apraxia of eyelid opening (ALO) secondary toidiopathic hypoparathyroidism. 相似文献
