    SINGLA A, FARGEN KM, HOH B. ONYX EXTRUSION THROUGH THE SCALP AFTER EMBOLIZATION OF DURAL ARTERIOVENOUS FISTULA. JOURNAL OF NEUROINTERVENTIONAL SURGERY. 2016;8(9):E38. DOI:10.1136/NEURINTSURG-2015-011879. REP MEDTRONIC LITERATURE REVIEW FOUND A REPORT OF PATIENT COMPLICATIONS IN ASSOCIATION WITH ONYX AND THE APOLLO CATHETER. THE PURPOSE OF THIS ARTICLE WAS TO REPORT A PATIENT WHO PRESENTED WITH SPONTANEOUS EXTRUSION OF ONYX FROM THE SCALP A FEW WEEKS AFTER EMBOLIZATION FOR A DURAL ARTERIOVENOUS FISTULA (DAVF). A MAN IN HIS SIXTIES WAS REFERRED WITH SYMPTOMS OF EPISODIC LEFT LIP NUMBNESS AND LEFT ARM WEAKNESS FOR FEW WEEKS. THERE WAS NO OTHER SIGNIFICANT PAST MEDICAL OR SOCIAL HISTORY. THE PATIENT WAS NEUROLOGICALLY INTACT ON EXAMINATION. OUTPATIENT CT ANGIOGRAM SHOWED ABNORMAL VESSELS IN THE RIGHT TEMPORAL LOBE SUSPICIOUS OF AN INTRACRANIAL VASCULAR MALFORMATION. HE UNDERWENT DSA WHICH REVEALED A BORDEN TYPE 3 DAVF. SUCCESSFUL ONYX-18 AND ONYX-34 EMBOLIZATION OF THE DAVF WAS PERFORMED VIA THE DISTAL LEFT OCCIPITAL ARTERY USING AN EV3 APOLLO DETACHABLE TIP MICROCATHETER, RESULTING IN OBLITERATION OF THE BILATERAL OCCIPITAL ARTERY SUPPLIES TO THE DAVF. THERE WAS STILL RESIDUAL DAVF SUPPLIED BY THE BILATERAL MIDDLE MENINGEAL ARTERIES AND THE RIGHT FALCINE ARTERY. DUE TO INCOMPLETE OBLITERATION VIA ENDOVASCULAR EMBOLIZATION, THE PATIENT UNDERWENT SURGICAL OBLITERATION OF THE DAVF 3 DAYS LATER. POSTOPERATIVELY THE PATIENT REMAINED NEUROLOGICALLY INTACT. THERE WAS NO ABNORMAL STAINING ON THE SCALP. HIS INCISION SITE REMAINED CLEAN, DRY, AND INTACT. HE WAS DISCHARGED HOME. THREE MONTHS LATER DURING A ROUTINE POSTOPERATIVE CLINIC VISIT, THE PATIENT PRODUCED A PLASTIC BAG CONTAINING MULTIPLE SMALL PIECES OF THE ONYX METALLIC CAST WHICH HE KEPT THAT HAD EXTRUDED OUT FROM HIS SCALP THROUGH SMALL SPONTANEOUS HOLES ABOUT 5 WEEKS AFTER THE PROCEDURE. ALONG WITH THE ONYX CASTS THE DETACHED TIP OF THE APOLLO MICROCATHETER HAD ALSO EXTRUDED. THESE AREAS OF SKIN EROSION WERE ABOUT AN INCH AWAY FROM THE SURGICAL INCISION SITE AND DID NOT RESULT IN WOUND COMPLICATIONS. THE SURGICAL INCISION SITE WAS COMPLETELY HEALED AT THE TIME OF THE CLINIC VISIT. HISTOPATHOLOGICAL STUDY SHOWED THAT ONYX EVOKED A MILD DEGREE OF INTRA AND PERIVASCULAR INFLAMMATION IN THE SUBACUTE (18 DAYS) AND CHRONIC (1¿6 MONTHS) PHASES AFTER EMBOLIZATION. GRANULOMATOUS INFLAMMATORY RESPONSE, INCLUDING MANY ELONGATED EPITHELIOID CELLS AS WELL AS SCATTERED FOREIGN BODY  GIANT CELLS, WAS SEEN IN THIS STUDY. NO INFLAMMATION WAS SEEN IN THE ACUTE PHASE. IT WAS BELIEVED THAT THE SPONTANEOUS EXTRUSION OF ONYX WAS SECONDARY TO THE INFLAMMATION FROM ONYX CAUSING EROSION OF THE VESSEL WALL AND SUBSEQUENTLY EROSION OF THE SKIN OF THE SCALP
