    STEPHAN MECKEL, WILLIAM MCAULIFFE, DAVID FIORELLA, CHRISTIAN A. TASCHNER, CONSTANTINE PHATOUROS, TIMOTHY JOHN PHILLIPS, PAUL VASAK, MARTIN SCHUMACHER, JOACHIM KLISCH. ENDOVASCULAR TREATMENT OF COMPLEX ANEURYSMS AT THE VERTEBROBASILAR JUNCTION WITH FLOW-DIVERTING STENTS: INITIAL EXPERIENCE. NEUROSURGER 73 (2013). DOI: 10.1227/01.NEU.0000431472.71913.07. BACKGROUND: LARGE OR GIANT COMPLEX VERTEBROBASILAR JUNCTION ANEURYSMS HAVE A DISMAL NATURAL HISTORY AND ARE OFTEN CHALLENGING TO TREAT WITH STANDARD ENDOVASCULAR OR NEUROSURGICAL TECHNIQUES. OBJECTIVE: TO REPORT INITIAL EXPERIENCE WITH ENDOVASCULAR TREATMENT OF THESE ANEURYSMS USING FLOW-DIVERTING STENTS (FDS). METHODS: TEN PATIENTS WITH FDS TREATMENT OF COMPLEX VERTEBROBASILAR JUNCTION ANEURYSMS WERE COLLECTED FROM 4 LARGE CEREBROVASCULAR CENTERS. CLINICAL/ANGIOGRAPHIC PRESENTATION AND OUTCOME WERE RETROSPECTIVELY ANALYZED. RESULTS: OF 10 ANEURYSMS, 7 PRESENTED WITH BRAINSTEM COMPRESSION, 2 WITH ISCHEMIA, AND 1 WITH SUBARACHNOID HEMORRHAGE, AND 3 WERE RECURRENT AFTER STENT-ASSISTED TREATMENTS. EIGHT WERE GIANT. MORPHOLOGY WAS FUSIFORM IN 5, FUSIFORM DISSECTING IN 1, AND MULTILOBULATED SACCULAR IN 4. SIX WERE PARTIALLY THROMBOSED. IN ADDITION TO FDS (MEAN NUMBER OF DEVICES, 3.9; RANGE, 1-9), CONTRALATERAL VERTEBRAL ARTERY SACRIFICE AND ADJUNCTIVE COILING WERE PERFORMED IN 9 AND 5 OF THE 10 PATIENTS, RESPECTIVELY. AT FOLLOW-UP, 5 OF 10 WERE COMPLETELY OCCLUDED, 4 SHOWED MINIMAL RESIDUAL FILLING, AND 1 WAS RETREATED WITH AN ADDITIONAL FDS. POSTINTERVENTIONALLY, WORSENING MASS EFFECT AND ISCHEMIC COMPLICATIONS WERE SEEN IN 2 AND 4 OF 10, RESPECTIVELY. CLINICAL OUTCOME WAS GOOD IN 6 (MODIFIED RANKIN SCALE SCORE, 0-2). FOUR FATALITIES WERE RELATED TO SEQUELAE OF SUBARACHNOID HEMORRHAGE, LATE FDS THROMBOSIS, PROGRESSIVE MASS EFFECT, AND DELAYED INTRACRANIAL HEMORRHAGE. CONCLUSION: FDS MAY BE USED TO TREAT COMPLEX VERTEBROBASILAR JUNCTION ANEURYSMS WITH OVERALL GOOD ANGIOGRAPHIC OUTCOME. A COMBINED RECONSTRUCTIVE/DECONSTRUCTIVE APPROACH APPEARS USEFUL TO AVOID ENDOLEAKS. FDS STRATEGIES, LIKE OTHER ENDOVASCULAR AND NEUROSURGICAL APPROACHES TO THESE LESIONS, ARE ASSOCIATED WITH SIGNIFICANT RISK AND THEREFORE SHOULD BE RESERVED FOR THOSE CASES IN WHICH ALTERNATIVE APPROACHES EITHER ARE DEEMED UNSAFE OR ARE LIKELY TO BE INEFFECTIVE. REPORTED EVENTS. - (CASE 5) IN A CASE INVOLVING A (B)(6) YEAR OLD MALE, AN INITIAL ATTEMPT OF STENT-ASSISTED COIL EMBOLIZATION WITH DETACHMENT OF 1 SOLITAIRE STENT HAD FAILED 3 MONTHS EARLIER. THE PATIENT WAS RETREATED WITH 2 FLOW-DIVERTING STENTS AND CONTRALATERAL VERTEBRAL ARTERY OCCLUSION.
