2024年11月7日 · Caroticocavernous fistulas represent abnormal communication between the carotid circulation and the cavernous sinus. They can be classified as direct or indirect which are separate conditions with different etiologies.

2024年11月2日 · Barrow caroticocavernous fistula classification divides caroticocavernous fistulas into direct (type A) or indirect (types B-D). This classification was proposed by Barrow et al. in 1985 1 and at the time of writing (mid-2016) remains the most widely used system for describing caroticocavernous fistulas.

Caroticocavernous fistula (CCF) is an abnormal communication between the carotid arterial circulation and the cavernous sinus. Various classifications have been proposed for CCF, the most frequently used and most broadly divides caroticocavernous fistula into two main types: direct and indirect CCF.

This appearance confirms bilateral indirect carotid cavernous fistula, each side supplied by meningeal branches arising from both internal maxillary arteries. Each cavernous sinus drains anteriorly through the ophthalmic vein.

2024年11月2日 · Caroticocavernous fistulas represent abnormal communication between the carotid circulation and the cavernous sinus. They can be classified as direct or indirect which are separate conditions with different etiologies.

2022年10月18日 · The cavernous sinus transmits multiple cranial nerves to the superior orbital fissure and foramen rotundum. These are: in the lateral wall from superior to inferior. oculomotor nerve (CN III) trochlear nerve (CN IV) trigeminal nerve (CN V) ophthalmic division; maxillary division: within the very inferolateral aspect of the cavernous sinus wall ...

This is a lateral view digital subtraction angiography with cannulation of the left common carotid artery. Following injection of contrast into the left common and internal carotid artery, contrast opacified the cerebral venous system, such as the cavernous sinus.

Caroticocavernous fistulae (CCF) are abnormal arteriovenous communications between the cavernous sinus and the carotid circulation. CCF may be divided into direct and indirect classifications.

2024年7月17日 · A cavernous sinus mass has a wide differential, including: meningioma; orbital apical inflammation with cavernous sinus involvement (Tolosa-Hunt syndrome) infection schwannoma any of the cranial nerves traversing the cavernous sinus: III, IV, V (V1 and V2) and VI; trigeminal schwannoma is the most common; cavernous hemangioma

There is a high flow, direct (type a) carotid cavernous fistula, filling exclusively from the right internal carotid artery, with flow more rapidly into the posterior part of the cavernous sinus and inferior petrosal sinus, and more slowly into the superior ophthalmic vein.
