AbstractDural arteriovenous fistulas (DAVFs) located within superior sagittal sinus (SSS) wall with direct cortical venous drainage are rare. They are also known as variant DAVF (vDAVF) and form a special subgroup of DAVFs. Their chance of presenting with aggressive features is high compared with transverse sigmoid sinus fistula. They drain directly into cortical veins (Borden type 3, Cognard type III and IV). A systematic English literature review of SSS vDAVF was made. Systematic literature review revealed a total of 31 published cases. These were commonly seen in male population, (24 males, 77.41%, 24/31). Average age of patients was 54 years. A total of 24 patients (77.41%, 24/31) had aggressive clinical presentations with 13 patients (41.93%, 13/31) having intracranial hemorrhages (ICH). Two patients had rebleeding (15.38%, 2/13). Middle portion of SSS was commonly involved (15 cases, 75%). A total of 25 (96.15%, 25/26) cases had patent SSS. Most of the fistulas were idiopathic (65.38%, 17/26), with trauma being a frequent etiological factor (26.92%, 7/26). Venous ectasia was seen in 19 patients (59.37%, 19/32). Middle meningeal arterial (MMA) supply was seen in all patients (100%, 26/26), with bilateral MMA supply in 21 cases (80.76%), and unilateral in 5 cases (19.23%). Twenty patients (62.50%, 20/32) received only endovascular treatment (EVT), while four patients had EVT followed by surgery (12.5%, 4/32). Transarterial route via MMA was the preferred treatment option (79.16%). Complete obliteration of fistulas was noted in all cases (100%, 30/30). No immediate complication was noted after EVT. As much as 92.30% patients showed good recovery. Thus, SSS vDAVF forms a special subgroup of DAVF, with aggressive presentation, and warrants urgent treatment. EVT is effective treatment option and can produce complete obliteration.

Research Avenue

Extensive research on resource-constrained innovation has been conducted by scholars and practitioners in recent years. An interesting research avenue is how firms explore the process of the new product development (NPD) and the ideas generation to foster resource-constrained innovation. However, despite the importance of product development and creative ideas under the resource-constraints contexts, innovation methods for applying to the resource-constrained innovation and designers have received comparatively less attention. As a remedy, this paper proposes a resource-constrained innovation method (RCIM) to generate ideas for the NPD. The RCIM is mainly divided into four sections: Developing the resource-constrained innovation approaches, developing the resource-constrained innovation dimensions, generating the creative ideas and evaluating the creative ideas. First, the resource-constrained innovation algorithms are developed based on success factors, characteristics, and attributes of resource-constrained innovation and the TRIZ (Teopия Peшeния Изoбpeтaтeльcкиx Зaдaч in Russian; Theory of Inventive Problem Solving in English) inventive principles via the systematic literature review (SLR). Second, the innovation dimensions are categorized to structure a target technology by means of the morphological analysis (MA) and the Derwent manual codes (DMCs) mapping based on collected patents. Third, the creative ideas are generated for the NPD by combining the innovation dimensions with the resource-constrained innovation approaches. Finally, the creative ideas are evaluated by the frugal criteria. The RCIM will stimulate designers’ creativity for achieving sustainability and innovation within constraint-based scenarios, MA and TRIZ.

Abstract Two cases of primary melanoma of the central nervous system originating from the dura mater and without involvement of the leptomeninges are described. In one case, the tumor was located extradurally with firm attachment to the dura mater and dural melanosis. In the other case, the dura was involved diffusely with multiple discrete masses of 1 to 3 mm in diameter. A literature review revealed five other cases of primary dural melanoma. A discussion of the origin of primary dural melanoma is presented.

Carotid Cavernous Fistulas

Spontaneous regression of direct carotid-cavernous fistulas (CCFs) is extremely rare. Most of the patients with direct CCFs are usually treated using endovascular techniques. Spontaneous obliteration of the direct fistulas probably results from thrombosis of the venous drainage and/or cavernous sinus. We report spontaneous closure of nine direct CCFs in nine patients. From literature review, we found another 37 patients with 43 fistulas due to spontaneous obliteration of bilateral lesions in six cases. There was no spontaneous closure in large-sized fistula. The factors associated with spontaneous thrombosis of the fistulas may be low-flow and small-sized fistula, hypotension, severe ocular manifestations, dissections or spasm of carotid artery, and increased intracranial pressure. Spontaneous healing of direct traumatic CCFs should be confirmed with cerebral angiography. Conservative treatment of direct CCFs should be carefully restricted in patients with normal vision or minimal visual impairment, and the patients must be monitored closely for any changes in visual function. Prompt endovascular treatment for complete obliteration of the fistula should be performed in patients with rapidly progressive visual loss. Venous thrombosis can still effect vision and rerouting towards cortical veins remains a concern. Because spontaneous resolution cannot be reliably predicted, the fistula then should be treated rather than waiting for spontaneous thrombosis.

This article describes the successful endovascular treatment of a dural arteriovenous fistula of a rare localization (the area of sphenoid bone lesser region). We examine one report of an unusually located dural arteriovenous fistula successfully treated with Onyx (ev3, Irvine, USA) using a combination of endovascular adjuvant techniques: pressure cooker and remodeling balloon protection of cerebral artery. The article includes previously published observations of such fistulas and discusses anatomic features and venous drainage of dural arteriovenous fistulas in the given location.

Dural Lymphoma

Primary dural lymphoma (PDL) is an extranodal non-Hodgkin lymphoma that accounts for less than 1% of all central nervous system lymphomas. Primary dural lymphoma grows from the dura mater, and it is often diagnosed as meningioma or acute subdural hematoma due to its radiological characteristics. Surgery is the gold standard of therapy; in many patients, PDL is relatively benign with good outcome. Authors report their experience in three patients affected by extranodal non-Hodgkin lymphoma (PDL) mimicking a meningioma.

Creativity Development

This paper aims to emphasize the necessity of introducing Project-Based Learning (PBL) to design enterprises in order to foster designers creativity and facilitate innovation of design enterprises. According to the literature review, creativity can be viewed as the first stage of innovation; PBL has at least two elements including solving real problems and group work that can provide conditions of creativity development. Moreover, creativity techniques such as brainstorming, mind mapping, checklist and morphological analysis are suggested to be integrated into PBL in the design enterprises.
