Transpalpebral approach for microsurgical clipping of an unruptured basilar apex aneurysm: case report and literature review.

BACKGROUND AND IMPORTANCE: The supraorbital "keyhole" approach has been described for the treatment of basilar artery aneurysms. Transpalpebral approach (TPA) is an alternative minimally invasive route to aneurysms of the Circle of Willis with excellent functional and cosmetic outcomes. CLINICAL PRESENTATION: 53-years-old female who presented with an incidentally found 6.3 mm BA aneurysm with 3.1 mm neck diameter, admitted to our department of neurovascular surgery. Clipping was performed through TPA, with endoscope assistance and intraoperative ICG angiography. The patient's postoperative course was uneventful and was discharged home on postoperative day 5 without any complications. CONCLUSION: First time in the literature described keyhole TPA with eyelid incision to BA aneurysm. TPA is technically difficult and requires some experience to work through deep and limited surgical corridor. This technique can be good alternative to traditional fronto-lateral, supraorbital keyhole craniotomies.

Transvenous embolization of indirect carotid-cavernous fistula via puncture of the cubital vein and distal radial artery.

Carotid-cavernous fistula (CCF) is a pathologic communication between carotid arteries and cavernous sinus. The goal of endovascular treatment is to completely interrupt the carotid-cavernous communication with preserving normal blood flow in carotid arteries. Embolization can be performed via transarterial or transvenous access depending on anatomy and angioarchitecture of fistula. In this report, we present a 64-year-old woman with indirect CCF. Effective and safe embolization of indirect CCF was performed using distal radial access for diagnosis and navigation and cubital vein for simultaneous venous access for therapeutic endovascular manipulations, completely avoiding femoral access.
