Abstract

Surgical suture endovascular embolization of brain arteriovenous malformations (AVMs) is an accepted method of preoperative treatment.A major drawback of AVM embolization with surgical sutures is that the sutures are not visible under fluoroscopy. An experimental study using swine is presented where surgical sutures were rendered radiopaque using platinum markers.

Postembolization angiogram. Both ascending pharyngeal arteries and the proximal part of the rete mirabile were occluded with radiopaque silk sutures. Arrows point to the stump of the occluded arteries.

Figure 5
Plain X-Ray film, AP view. Short arrows point to the two markers ("tip and tail" markers) of a suture that was injected in the right ascending pharyngeal artery. Long arrows point to the radiopaque tip markers of sutures injected in the left and right ascending pharyngeal arteries. The arrowhead points to the tip of the microcatheter.
