Abstract

Spinal cord infarction is an unusual complication of intracranial neuroendovascular intervention. The authors report on two cases involving spinal cord infarction after endovascular coil embolization for large basilar-tip aneurysms. Each aneurysm was sufficiently embolized by the stent/balloon combination-assisted technique or double catheter technique. However, postoperatively, patients presented neurological symptoms without cranial nerve manifestation. MRI revealed multiple infarctions at the cervical spinal cord. In both cases, larger-sized guiding catheters were used for an adjunctive technique. Therefore, guiding catheters had been wedged in the vertebral artery (VA). The wedge of the VA and flow restriction may have caused thromboemboli and/or hemodynamic insufficiency of the spinal branches from the VA (radiculomedullary artery), resulting in spinal cord infarction. Spinal cord infarction should be taken into consideration as a complication of endovascular intervention for lesions of the posterior circulation.

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
