There are few documented cases of bradycardia or asystole occurring during Onyx embolization of intracranial dural arteriovenous fistulas (DAVFs), although these events are more commonly observed in open neurosurgical procedures, particularly those involving the skull base. We present a case treated for a ruptured paramedian occipital DAVF. During the administration of Squid into the middle meningeal artery, while balloons were inflated in the large occipital arteries bilaterally to control the flow during embolization of the DAVF, the patient experienced an abrupt episode of sinus bradycardia, which recurred after a second injection of Squid. After temporarily halting the injections and deflating the balloons, a third injection was successfully administered without complications, allowing total exclusion of the fistula.

Percutaneous device closure of atrial septal defect (ASD) is an alternative treatment to surgery. The main advantages of the percutaneous approach include avoidance of surgery, short procedure time and hospital length, in addition to comparable rates of complications. However, percutaneous device closure is associated with infrequent early and late complications including device embolization, air embolism, cardiac tamponade and thrombotic complications. We report a rare complication of silent and late device embolization of the ASD occluder device into the right pulmonary artery, three months after implantation.

Delayed rupture of intracranial aneurysms after endovascular treatment is a rare but serious complication. We report the first documented case of late aneurysmal rupture following treatment with a Contour intrasaccular device. A patient in their 60s with a basilar tip aneurysm underwent endovascular treatment using a 14-mm Contour device. Fifteen months later, the patient presented with a fatal intraventricular hemorrhage, and imaging revealed device displacement and aneurysm growth. This case underscores the importance of meticulous device sizing and follow-up, especially for large aneurysms.
