Precision matters.... ➪🧠

External Ventricular Drain (𝗘𝗩𝗗) insertion is all about surface landmarks:
- 𝗘ntery point.
- 𝗧rajectory.
- 𝗩𝗲𝗻𝘁𝗿𝗶𝗰𝘂𝗹𝗮𝗿 - Target.

𝗥especting ventricular anatomy—small angles, big consequences.

1- 𝗦𝗼𝘂𝗿𝗰𝗲𝗱: sinusitis, mastoiditis/otitis, hematogenous spread, trauma, post-op.
2- 𝗟𝗼𝗰𝗮𝘁𝗶𝗼𝗻𝘀: frontal & temporal lobes.
3- 𝗦𝘆𝗺𝗽𝘁𝗼𝗺𝘀: headache, fever, focal deficits (classic triad is uncommon)
4- Common 𝗢𝗿𝗴𝗮𝗻𝗶𝘀𝗺𝘀: streptococci & staphylococci
5- 𝗗𝗶𝗮𝗴𝗻𝗼𝘀𝗶𝘀: CT with contrast + MRI (DWI is key)
6- 𝗦𝘁𝗮𝗴𝗲𝘀: cerebritis → capsule formation.
7- 𝗧𝗿𝗲𝗮𝘁𝗺𝗲𝗻𝘁: IV antibiotics ± stereotactic aspiration or excision.
8- 𝗢𝘂𝘁𝗰𝗼𝗺𝗲: many recover well, but mortality remains significant

(👀 , 👅 and the 🧠)

The movement of the eyes and tongue is controlled by 𝗙𝗼𝘂𝗿 pure motor cranial nerves.
- The oculomotor (𝘾𝙉 III).
- The trochlear (𝘾𝙉 IV).
- The abducens (𝘾𝙉 VI).
- The hypoglossal (𝘾𝙉 XII).

* All four neuclei are located in the midline.
* All four nerves embrologicaly are somatic motor origin.
* All are pure motor and voluntary movement.

All are connected through internal fibers for better coordination of the eyes and tongue movement.

Cerebral arteriovenous malformation (𝗔𝗩𝗠) AVM Embolization: Pre- and Post-Treatment Angiographic Comparison

The left panel demonstrates a grade II cerebral AVM consisting of multiple 𝗠𝗖𝗔 feeding arteries, a compact nidus, and an early opacified draining vein, indicating high-flow arteriovenous shunting and absence of a normal capillary bed.
- Such hemodynamic stress predisposes to rupture and intracranial hemorrhage.

- Endovascular embolization was performed via superselective microcatheterization of the arterial feeders, followed by controlled injection of 𝗢𝗻𝘆𝘅 18—a low-viscosity ethylene-vinyl alcohol copolymer formulation—allowing deep nidus pe*******on and cohesive filling while minimizing reflux.

- The right panel, obtained post-embolization, reveals near-complete angiographic obliteration of the nidus and restoration of normal cerebral venous drainage patterns.

This illustrates the efficacy of liquid embolic agents in achieving durable flow reduction and preparing the lesion for potential surgical resection or stereotactic radiosurgery.

A carotid–cavernous fistula (CCF) 𝗮𝗻𝗱 𝗰𝗼𝗻𝗷𝘂𝗻𝗰𝗶𝘃𝗮𝗹 𝗰𝗼𝗿𝗸𝘀𝗰𝗿𝗲𝘄 !

- Abnormal connection between the carotid arterial system and the cavernous sinus, leading to high-flow shunting of arterial blood into the venous system.
- This elevated venous pressure causes congestion of the orbital veins, resulting in classic ocular findings such as:
* pulsatile proptosis
* chemosis
* conjunctival arterialization, often described as “𝗰𝗼𝗿𝗸𝘀𝗰𝗿𝗲𝘄” vessels.
^ These twisting, engorged conjunctival vessels reflect the high-flow state and impaired venous drainage seen in CCFs.
