Sir,

A 27-year-old lady presented with progressive proptosis of right eye of three months duration. On examination, she was short-statured, had curly wispy hair, pinched nose, hyper-pigmented extremities, swollen joints without hypermobility, wrinkled, dry, thin skin without hyper-elasticity with visible underlying veins. She had proptosis of right eye with chemosis and normal visual acuity and visual fields. Both pupils were equal in size with no relative afferent pupillary defect. Fundoscopy revealed blurring of right disc margin. Movements of the right eye were minimally restricted in all directions. Magnetic resonance imaging of orbits and cerebral computed tomography-angiogram (CTA) revealed a dilated right superior ophthalmic vein (SOV) and dilated cavernous varix [Figure 1]. With a diagnosis of a caroticocavernous fistula (CCF) in a patient with  Ehlers-Danlos syndrome More Details (EDS), we planned a combined diagnostic angiogram and intervention to minimize vascular trauma. During vascular access, she had intimal dissection of right common femoral artery, which was managed conservatively. A right direct CCF (Type A) was confirmed [Figure 2] and [Figure 3]. She was heparinised with 5000 U of heparin intravenously. A 6F guiding catheter (Neuron catheter (Penumbra)) was placed and a 0.008-in microcatheter (MAGIC 1, 2 FM 180, BALT) was advanced across the defect in the internal carotid artery (ICA) and into the cavernous sinus. A detachable Goldbal balloon (9 mm × 14 mm, BALT) was used to occlude the fistula. A final check arteriogram showed non-opacification of the SOV, with minimal residual filling of the inferior petrosal sinus [Figure 4]. Post procedure patient remained on heparin (1000 U per h) for 12 h. She was kept in the intensive care unit (ICU) for 24 h. Her proptosis disappeared over a period of one week. She is completely asymptomatic during follow-up after nine months.

In the 1960s, the vascular component of EDS was recognized, and EDS 4, the vascular type, was identified by Andras Barbaras. [1] This subcategory remained the most malignant form of EDS because of the high probability of developing spontaneous blood vessel rupture from aneurysms, dissections, and transmural tears. [1],[2] They account for less than 4% of all EDS patients. [3]

Our patient had a direct cavernous fistula, characterized by carotid arterial blood shunting directly into the venous cavernous sinus. The treatment options for direct CCF include transarterial coiling via the ICA, transvenous coiling through the superior or inferior petrosal sinuses or an ophthalmic approach via the ophthalmic vein. [4] Despite taking precautions with gentle catheter manipulation, our patient had a dissection of the femoral artery at the puncture site. Attempts at balloon embolization of CCFs by transarterial and transvenous routes have both been complicated by lethal hemorrhages. [5] Arteriography is indicated only if coil embolization is considered. [6],[7] We had excluded pre-existing arterial dissections in the abdominal aorta, iliac arteries by CTA and in the carotid arteries by ultrasonography. Thus diagnostic angiography and endovascular intervention through balloon occlusion of the CCF were performed together to minimize vascular trauma. We believe that the use of a glide diagnostic catheter, a high-profile soft guiding catheter like the Neuron catheter (Penumbra), as were used, could further minimize traumatic events during the procedure.
