Spontaneous rupture of the superficial femoral artery (SFA) is extremely rare. We report an interesting case of an elderly man presented with a history of hearing a click sound in his left lower thigh followed by sudden onset pain, swelling, and discoloration in the left lower limb while coming back from the bathroom. He was a known case of chronic kidney disease, and cirrhosis of the liver with moderate left ventricular (LV) dysfunction. We treated the ruptured SFA using overlapping stent grafts with CO 2 angiography. The pseudoaneurysm got thrombosed. The pain and swelling of the left lower limb gradually subsided. The patient went home walking. [ABSTRACT FROM AUTHOR]

Dural arteriovenous fistulas (DAVFs) are acquired pathological arteriovenous connections involving vessels that usually supply the meninges. A DAVF in the region of the hypoglossal canal is a rare form of fistula that involves the anterior condylar confluence or anterior condylar vein. We report a case of hypoglossal canal DAVF that was successfully embolized transvenously through a superior ophthalmic vein (SOV) approach. After failed attempts through jugular access, our patient was treated by a unique percutaneous direct puncture approach through the SOV, achieving complete obliteration of the fistula. A step-by-step description of the endovascular technique was described. The clinical course was uneventful without any new neurologic deficit. The eye symptoms and third nerve palsy had completely resolved at the 3-month follow-up visit. Hypoglossal canal DAVFs are rare and may exhibit complex venous drainage patterns. Knowledge of the complex venous anatomy is essential for planning an alternative transvenous route if the standard approach is not feasible. Xper CT (Philips Healthcare, Best, The Netherlands) is an excellent tool for identifying the exact site of the fistula as well as for confirming a safe position of the catheter tip for successful occlusion of this complex dural AV fistula.

Blister aneurysms are intracranial arterial lesions originating at nonbranching sites of the dorsal supraclinoid internal carotid artery and basilar artery. 1 Among different treatment options, the use of flow-diverting devices is gaining popularity and has the potential for becoming the standard of care. 2 Radiological evaluation of flow diverter braid expansion and vessel wall apposition during procedure has become useful in preventing life-threatening complications. Incomplete coverage of an aneurysm neck, kinking, or incomplete expansion and malapposition of a stent carries a significant risk for thromboembolic events. 34 [ABSTRACT FROM AUTHOR]
