In a patient with progressive ophthalmological problems, including uncontrolled intraocular pressure related to a cavernous sinus dural arteriovenous fistula, urgent intervention may be necessary to prevent permanent visual loss. We report a case in which inadequate transarterial embolisation and lack of access for transvenous catheterisation, including a direct approach through ...

OBJECT: Historically, the sagittal suture has been used as an external landmark to indicate the middle portion of the superior sagittal sinus (SSS). The goal of this study was to verify this relationship. METHODS: The authors examined 30 adult cadavers to reveal the location of the SSS with respect to ...

To evaluate the role of transvenous embolisation including its efficacy and safety in the treatment of intracranial dural arteriovenous fistulas (DAVFs), we retrospectively analysed seven cases of intracranial DAVFs treated with transvenous embolisation in combination with arterial embolisation. Four DAVFs were in the cavernous sinus, two in the transverse-sigmoid sinus, ...

We report cases of posterior cranial fossa arteriovenous fistula (AVF) with presenting with exophthalmos, chemosis and tinnitus in 26- and 66-year-old men. The final diagnoses was vertebral artery AVF and AVF of the marginal sinus, respectively. The dominant venous drainage was the cause of the unusual presentation: both drained from ...

A 34-year-old man developed fever, headache, nausea, double vision, exophthalmus, ptosis, disturbance of vision and oculomotor nerve palsy. Magnetic resonance imaging and cerebral angiography led to the clinical diagnoses of cavernous sinus thrombophlebitis and suspicion of bacterial aneurysm of the left internal carotid artery, respectively. Peptostreptococcus was detected in blood ...

OBJECTIVE: The endoscopic surgical anatomy of the cavernous sinus was studied to establish an anatomic basis for endoscopic endonasal cavernous sinus surgery. METHODS: Five adult cadaveric heads were studied with 0-, 30-, and 70-degree 4-mm rod-lens endoscopes. The posterior wall of the sphenoidal sinus was approached via a paraseptal, middle ...

Summary: A case of traumatic persistent pnmltlve trigeminal artery (PPTA) cavernous sinus fistula treated with GDC embolisation is reported. Because of the small lumen of PP TA, posteriorly directed course and flow contribution from the posterior circulation, balloon embolisation via the carotid system was not considered appropriate. The fistula was ...

Retrograde tracing and immunohistochemistry was used in rats to investigate whether the ganglia in the cavernous sinus contribute to cerebrovascular innervation. The cavernous sinus ganglia in rat include the cavernous part of the pterygopalatine ganglion (PGC) and small cavernous ganglia (CG). The tracers, fluorogold and fast blue, were applied to ...

Transverse-sigmoid sinus dural arteriovenous malformations (DAVM) are uncommon vascular lesions for which complete cure may be difficult to obtain. A wide variety of treatments for these lesions include observation, arterial compression, surgical resection, and endovascular embolization. We propose that transverse-sigmoid sinus DAVM can be completely cured by occluding the ipsilateral ...

A patient with diplopia had a carotid cavernous fistula associated with a persistent primitive trigeminal artery that was seen with angiography. Balloon occlusion of the carotid cavernous fistula resulted in flow stasis of the persistent primitive trigeminal artery and resolution of the symptoms. Persistent primitive trigeminal artery may be associated ...

A patient comatose after acute anoxia developed bilaterally synchronous, periodic myoclonic jerks most prominently in the bilateral upper limbs. Although the myoclonus seemed to occur spontaneously, electrophysiological studies showed that the myoclonic jerks correlated in timing and size with arterial pulses, and was suppressed by massage over the carotid sinus. ...

Embolization of a carotid cavernous fistula (CCF) by means of a detachable balloon is an established method for treating CCFs while preserving a patent parent internal carotid artery (ICA). However, failure to embolize the CCF may occur on a few occasions, such as when the balloon cannot pass through the ...

A 72-year-old woman who presented with a unilateral oculomotor nerve palsy was shown to have a very rare condition: multiple dural arteriovenous fistulae (DAVF) involving the cavernous and sphenoparietal sinuses. The sphenoparietal DAVF was cured completely by transarterial embolisation. Symptomatic relief was accomplished by this procedure. The cavernous sinus DAVF ...

We report a newly evidenced cause of venous pulsatile tinnitus--the aneurysm of a dural sigmoid sinus. A 33-year-old patient presented with an incapacitating pulsatile tinnitus of 6 months' duration in the left ear. The radiological workup evidenced an aneurysm of the left sigmoid sinus. Selective endovascular coil occlusion of the ...

Internal maxillary artery ligation for persistent posterior epistaxis is traditionally performed via the transantral approach. Although usually effective in controlling the bleeding it carries significant risks, including damage to the infraorbital nerve, damage to dentition and oro-antral fistula formation. The alternative procedure of endoscopic ligation of the sphenopalatine artery at ...

A-type and B-type natriuretic peptides (ANP and BNP) are secreted into the systemic circulation via the coronary sinus. Plasma levels of ANP and BNP at the coronary sinus should directly determine the systemic circulating levels. However, the metabolic clearance of these hormones are dependent on similar systems, natriuretic peptide clearance ...

A 65-year-old man with a dural carotid-cavernous fistula (DCCF) presented with sudden onset of painful trochlear nerve paresis. Typical signs of DCCF including conjunctival arterialization, chemosis, and proptosis did not become manifest until 4 months later. This unusual presentation of DCCF was caused by drainage of the fistula posteriorly into ...

The lengthy, continuous, slender extradural neural axis compartment (EDNAC), which extends from the coccyx to the orbit, has been not so much discovered as recognized. Through this compartment run arteries, myelinated and unmyelinated nerves, and valveless veins. Adipose tissue is abundant in the orbital and spinal segments, possibly due to ...
