Persistent primitive trigeminal artery associated with cerebrovascular diseases and other cerebrosis
Journal of Interventional Radiology, 2009Co-Authors: Li Ming-huAbstract:Persistent primitive trigeminal artery (PPTA) is the most common permanent abnormal vascular anastomosis between carotid artery and basilar artery. PPTA is a rare cerebrovascular variation and is often associated with cerebrovascular disease (CVD). Clinically, PPTA manifests itself in symptoms such as trigeminal neuralgia, oculomotor Paralysis, Abducens Nerve Paralysis, subarachnoid hemorrhage, etc. This paper aims to review 116 PPTA cases with CVD and other cerebrosis, which have ever been reported since 1983 in English or Chinese medical literature.

Sphenoid wing dural arteriovenous fistula: A case report and literature review.
Surgical neurology international, 2020Co-Authors: Yu Shimizu, Kazuhiko Tokuda, Cheho ParkAbstract:Background Sphenoid wing dural arteriovenous fistula (SWDAVF) is rare that is typically fed by middle meningeal artery feeders and that drain through the sphenoparietal sinus or middle cerebral vein. Here, we report a case of SWDAVF treated by coils placed in the venous aneurysm through the contralateral cavernous sinus (CS). Case Description A 37-year-old woman was admitted to our hospital with headache and bilateral oculomotor Nerve palsy. Magnetic resonance images and an angiogram showed a venous aneurysm in the right middle cranial fossa. A DAVF, consisting of two main feeders, was diagnosed based on the angiogram findings. The fistula drained into the left inferior petrosal sinus (IPS) through the left CS and right IPS. Given the remarkable extent of venous ectasia together with the headache and right Abducens Nerve Paralysis, endovascular treatment was initiated. A transvenous approach through the right IPS was not feasible, as it is strenuous to insert the microcatheter into the right IPS. Thus, we tried an approach through the left IPS. The venous aneurysm was embolized with coils. The postoperative course was uneventful, and postoperative cerebral angiography confirmed disappearance of the fistula. Conclusion A SWDAVF is extremely rare. In our case, since the AVF drained into the contralateral CS, contralateral ocular symptoms occurred. Endovascular occlusion of the venous aneurysm and fistula was achieved through a transvenous approach.

Bilateral traumatic Abducens Nerve Paralysis with cervical spine flexion injury
European Spine Journal, 1996Co-Authors: M. Uzan, M. Hanci, A. Ç. Sarioğlu, M. Y. Kaynar, H. BozkuşAbstract:Bilateral traumatic Abducens Nerve palsy is a rare condition. We report a case associated with cervical spine flexion injury. This may be the first such case report, as no similar case was found in our review of the literature. The mechanisms of injury in this case are relevant to theories that explain hyperextension injuries.

Abducens Nerve palsy as a postoperative complication of minimally invasive thoracic spine surgery: a case report
BMC Surgery, 2016Co-Authors: Luiz Henrique Dias Sandon, Gun Choi, Eunsoo Park, Hyung-chang LeeAbstract:Background Thoracic disc surgeries make up only a small number of all spine surgeries performed, but they can have a considerable number of postoperative complications. Numerous approaches have been developed and studied in an attempt to reduce the morbidity associated with the procedure; however, we still encounter cases that develop serious and unexpected outcomes. Case Presentation This case report presents a patient with Abducens Nerve palsy after minimally invasive surgery for thoracic disc herniation with an intraoperative spinal fluid fistula. A literature review of all cases related to this complication after spine surgery is included. Despite the uncommon nature of this type of complication, understanding the procedure itself, the principle occurrences and outcomes following the procedure, the physiopathogical features of Abducens Nerve palsy, and the possible adverse effects of spinal surgery, including minimally invasive procedures, can enable an early diagnosis of complications and facilitate the procedure. Conclusions In spite of being very rare and multifactorial, uni- or bilateral Abducens Nerve Paralysis carries significant morbidity and can occur as a postoperative complication after conventional or minimally invasive spine surgery. This condition requires an accurate diagnosis and adequate multidisciplinary follow up.
