RESULTS: All specimens treated with EMBOLYX showedno angiographic evidence of recanalization. At sacrifice alluteri grossly appeared normal. The only instance of endometrial necrosis occurred in a single sheep embolizedwith PYA bilaterally. Both agents were seen to penetrateto similar size vessels (400-500 microns). The microscopicchanges seen with both agents was identical and consisted of intimal hyperplasia and foreign body reactionwith the presence of giant cells. PYA panicles were seenmicroscopically in 94% of uterine segments when bilateralembolization was successful whereas, EMBOLYX panicleswere seen in only 46%. No evidence of ovarian infarctionwas seen with either agent. Permanent main uterine artery occlusion was the rule with EMBOLYX; while all uterine arteries remained patent following the use of PYA.

Uterine Artery Embolization in the Sheep ModelUsing a New Embolic Agent, Embolyx
JI. SWischuk, Peoria, I1 • F Castaneda • R. Ii • K. Young
PURPOSE To determine the depth of penetration andthe effects of transcatheter uterine artery embolizationwith EMBOLYX in sheep.
MATERIAL AND MElliODS: Uterine arteries of 10 sheepwere embolized with EMBOLYX , Polyvinyl alcohol par·ticles (PYA) or both. Three sheep were embolized withPYA (350-500 microns), four sheep were embolizedwith EMBOLYX (two each with 6.5% andl0% solutions)and three sheep had one uterine artery embolized withPYA and the other with EMBOLYX (6.5%). Successfulembolization was achieved in 18 uterine alteries. All animals were sacrificed at 3-4 weeks. The uteri andovaries were explanted and examined macroscopicallyand microscopically. Microscopic sections were takenthrough the main uterine artery, ovaries and the body,and horns (proximal, mid, and distal) of the uteri to determine the distribution of embolic agents.
CONCLUSION: EMBOLYX appears to be safe, causingsimilar microscopic changes when compared to PYA.uterine infarction did not occur with the use of EMBOLYX. Although both agents penetrated to similar levels, the distribution of EMBOLYX throughout the uteruswas more sporadic. In addition, Embolyx causes moreproXimal occlusion when compared to PYA.

GoP Siskin, Albany, NY • B.F Siainken • K. Dowling •
P Mea • j. AIm • E.G. Dolen
PURPOSE: To assess the feasibility of performing uterine fibroid embolization as an outpatient procedure.
MATERIALS AND MElliODS: 73 consecutive patients(mean age 44.3 years) underwent uterine artery<None>embolization during a 12-month period. Embolizaton was performed with 350-500u polyvinyl alcohol particles (67173) or gelfoam pledgets (6173). Atdischarge, patients were given instructions regardingthe expected symptoms after embolization and wereprescribed Prochlorperazine, Ketorolac, Meperidine,and Hydrocodone for symptomatic relief. All patientswere telephoned within 24 hours of discharge. During follow-up, a questionnaire was administered toevaluate the periprocedural experience. 3-monthclinical follow-up is available in 42 patients and imaging was performed at 6 months in 22 patients.
RESULTS: Presenting symptoms included menorrhagia(n=25), bulk-related symptoms including distension,incontinence, or pain (n=l1), or both (n=37). 71173patients were discharged 6-8 hours after embolization; 2 patients required overnight observation 0 dueto post-procedure hypertension and 1 due to a lateprocedure completion time). At the first follow-upphonecall, symptoms included pelvic pain in 82.2%(60173), fatigue in 75.3% (55173), nausea/vomiting in43.8% (32/73) and a vaginal discharge in 17.8%(3173). 5 patients called our staff to obtain additionalmedication instfllctions(n=3) or to request additionalmedication for pain control (n=2). Symptoms werecontrolled with discharge medications in 71/73 patients. 1 patient visited the emergency room and required admission for additional pain control duringthe first 48 hours after discharge. 69/73 patients weresatisfied with the decision for home discharge. Themean uterine volume reduction in 22 patients imagedat 6 months was 49.2%. 88.1% of patients with 3month clinical follow-up reported improvement orelimination of symptoms.
CONCLUSION: With defined telephone follow-up, staffavailability, and a protocol designed to alleviate thepost-procedure constitutional symptoms, uterine arteryembolization can be safely performed as an outpatientprocedure without sacrificing patient comfort.

peri mental uterine embolization because of uterine blood supply similar ro that of human. Four different sizes, 150-250, 250-400, 400--<)00 and 600-1000~m of PYA pal1icles (Ultra-Ivalon, Nycomed, France) and four sizes, 100-300, 300-500, 500-700 and 700-900~m of calibrated microspheres (Embosphere , Biosphere Medical, USA) were compared in 8 groups of animals sacrificed 5 days after embolization. Ease of injection and angiographic occlusion were compared. Embolic particles were also compared according ro MR imaging studies and histopathologic fearures (uterine necrosis and location of the particles).
RESULTS: No occlusion of the 5-French catheter was observed with microspheres even of 700--900pm diameter. Score of urerine necroSis was higher with small panicles (diameter<300~m) than with larger particles (p=O.02). Necrosis was higher with 150-250pm PYA particles (SO% of the uterus) than with 100--300pm calibrated microspheres (300/0 of tbe uterus) (p<O.OS). Uterine necrosis was less than 5% of the uterus, using large microsphe res. All types of PYA particles were located proximally in aggregates and distally (vessels ranging from 300 to 1000pm). Conversely, the diameter of occluded arteries was well correlated with the size of the microspheres used. Small calibrated microspheres were located distally. Microspheres smaller than SOOpm were occasionaly found inside the ovaries through a patent utero-ovarian anasromosis.
CONCLUSIONS: Our specific experimental model provides comprehensive assessment of physiopathologic uterine response to embolization. PYA particles are associa ted with intense uterine necrosis and extensive arterial occlusion. Calibrated microspheres which are associated with less necrosis permit a more controlled a([erial occlusion than PYA particles. Panicles larger than 500pITI should not reasonably be used in clinical practice to avoid ischemic damage on the ovaries.

Measurements of Skin Dose and Estimated Ovarian Dose Associated With Uterine Fibroid EmboUzatioll! A Follow-Up Study With Rerrned
Technique and State of the Art Equipment B. Nikolic, Washington, DC • IE. Spies . S.M. Walsh. ML Lundsten . AR. Roth
PURPOSE: To determine the absorbed skin dose (ASD) and estimated absorbed ovarian dose (EAOD) that occu rs during uterine fibroid embolization (UFE) using refined technique and srate-of-the-al1 equipment.
METHOD AND MATERIAL The absorbed dose was measured in 12 patienrs who underwent UFE procedures. All UFE procedures were performed using low frequency pulsed fluoroscopy with focus on limitation of magnified and oblique fluoroscopy . Lithium fluoride
dosimeters were placed both in the posterior vaginal fornix and on the skin at the beam entrance site. The vaginal dose was used to approximate the EAOD. Fluoroscopy time and exposures were recorded. The mean values for all patients were calcu lated and compared to published EAODs for other conunon radiographic and radiotherapeutic procedures, to threshold doses for induction of deterministic skin injury and to our previous measurements from UFE procedures mat were obtained with non-pulsed fluoroscopy.
RESULTS: Mean fluoroscopy time was 13 min. (range 7.6-21.3 min) and mean number of angiographic exposures was 17 (range 14--22). The mean EAOD was 11.0 cGy (range 2.2- 23.2 cGy) and the mean ASD was 57.42 cGy (range 12.9- 110. 1). This compares to published values of EAOD for double contrast BE (0.311-0.79 cGy), hysterosalpingiography (0.075-0.374 cGy), fallopian tube recanalization (0.85 cGy), UFE with non-pulsed fluorosocpy (22.34 cGy, range 4.25-65.08 cGy) and threshold doses for induction of determirtistic radiation injury to the skin (300-500 cGy).
CONCLUSION The ASD and EAOD from UFE procedures performed with refined technique and the use of state-of-the-alt equipment remains an order of magnitude grea ter than from common fluoroscopic procedures. However, using pulsed fluorosocpy with emphasis on reduction of absorbed radiation dose, can substantially reduce ASD and EAOD to 1/3 and 112 when compared to UFE performed with non-pulsed fluoroscopy.

Bilateral Uterine Artery Embolization for theTreatment of Menorrhagia Due to AdenomyosisG.P. Siskin, Albany, NY • ME Tublin • B.P. Stainken •
K. Dowling • I Ahn • E. G. Dolen
PURPOSE- To evaluate the use of bilateral uterine arteryembolization in the treatment of menorrhagia due toadenomyosis.
MATERIALS AND MElliODS: 14 patients (mean age46.7 years, range 37-56 years) with adenomyosis andmenorrhagia underwent bilateral uterine artery embolization. The diagnosis of diffuse adenomyosis wasbased on a maximum junctional zone thickness ~12
rom. at fast spin echo imaging. Focal adenomyosis wasdiagnosed if there was focal thickening of the junctional zone. Uterine artery embolization was performed with standard technique, utilizing 350-5001l
polyvinyl alcohol particles. Clinical response wasmeasured with a questionnaire administered 3 and 6months follOWing embolization. Follow-up MRI wasperformed 6 months after embolization.
CONCLUSIONS: Our limited experience suggests thatuterine artery embolization may be effective in treatingsymptomatic uterine leiomyomata despite the presence of adenomyosis. The majority of patients experience symptomatic relief, decrease in size of leiomyomata and uterine volume despite stable appearanceof the adenomyosis.
RESULTS: Bilateral uterine artery embolization was technically successful in all patients. Diffuse adenomyosiswas present in 10/14 patients with a mean junctionalzone thickness of 18.1 mm. (range 12-30 rom.). Focaladenomyomas were present in 4/14 patients. 9/14 patients had uterine fibroids in addition to adenomyosis.3-month clinical follow-up is available in 11/14 patients.6-month clinical and imaging follow-up is available in6/14 patients. At 3 months, 10/11 patients (90.1%) reported significant improvement of their presentingsymptoms while 1/11 reported no change. Follow-upimaging at 6 months demonstrated a mean decrease inuterine volume of 47.6% (range 27.9-65.0%). The meandecrease in volume of the 3 focal adenomyomas imaged at 6 months was 74.3%. In 3 patients with diffuseadenomyosis, the mean decrease in junctional zonethickness was 39.4% at 6 months. 5/6 patients imaged at6 months had fibroids as weJJ as adenomyosis; themean decrease in fibroid volume was 57.4%.
oma of 52% (n=13). MRI at one year (n=4) showed amean decrease in uterine volume of 44%, and decreasein volume of dominant leiomyoma was 87%. No significant change in the MRI appearance of adenomyosis wasnoted at 3 months and one year.

CONCLUSION- Most patients arranging a consultationto discuss uterine fibroid embolization were self-referred after learning about the procedure from television news, newspaper articles, and the Internet. Utilizing a hospital's public relations resources andestablishing a presence on the Internet are thereforecritical first steps in starting a uterine fibroid embolization service. The single largest referral sourceremains the gynecologist, stressing the importance ofeducating and developing ties with staff and community gynecologists.
a family member of friend (9/114; 7.9%), newspaper articles (8/114; 7.0%), or other other sources includingradio broadcasts, magazines, health fairs, and primarycare physicians. 78/114 (68.4%) of patients undergoinga consultation decided to undergo this procedure. Themean delay between the consultation and procedurewas 54.1 days. There was no significant difference inthe distribution of referral sources between the patientsscheduling or not scheduling the procedure after consultation (X2=2.023; p~0.20).
RESULTS: Technical success was achieved in all patientswith uterine leiomyomata and concomitant adenomyosis, without complications (n=13). At 3 months,92% (12/13) reported moderate to marked improvement in bleeding, 92% (11/12) moderate to marked improvement in pain/pressure, and 92% (12/13) overallsatisfaction with treatment. At 6 months, 90% (9/10) reported moderate to marked improvement in bleeding,750/0 (6/8) moderate to marked improvement inpain/pressure, and 67% (6/9) overall satisfaction withthe procedure. At one year, 80% (4/5) reported moderate to marked improvement in bleeding, 100% (3/3)
moderate to marked improvement in pain/pressure,and 60% (3/5) overall satisfaction with procedure. MRIat 3 months showed a mean decrease in uterine volumeof 39% (n=12), and mean decrease in dominant leiomy-
in decreases in uterine volwne, focal adenomyoma volume,and junctional zone thickness in this patient population.

Uterine Arterial Embolization for the Treatmentof Symptomatic Adenomyosis of the Uterus
C. Ahn, Sungnam, South Korea • WH. Lee·
T. W Sunwoo • YS. Kho
MATERIALS & ME71iODS: Uterine arterial embolization using polyvinyl alcohol particles sized 250-710micrometers was performed in 65 pa'tients (mean;40.6 years, range; 25-53 years) w(th dysmenorrhea,menorrhagia, or bulk-related symptoms (heaviness,urinary frequency) due to adenomyosis. All patieatswere evaluated with contrast enhanced dynamicmagnetic resonance imaging (MRl) before the procedure and 35 months (range; 31-238 days) after. Clinical symptoms were also assessed at the time of MRIbefore and after embolization.
RESULTS: Implantation success was 173/180 (96.1%)overall, and 99/101 (98%) after Jan 1, '98; 2/7 failuresreqUired immediate conversion to open repair (1.1%);5/7 were simply aborted. Though 3/392 AAAs rupturedduring the preliminary workup and planning (2 died, 1survived emergency operation elsewhere), no patient(0%) has experienced AAA rupture after TE. Operativemortality (30d) was 7/180 (3.9%), Major non-fatal perioperative complications occurred in 29/180 06.1%). Averages for LOS were: median=3d, mode=2d,mean=4.0±3.1d. There were 9 late deaths unrelated toTE. Of .32 (17.8%) patients with endoleaks, 3 self-resolved, 5 died of unrelated causes, 5 undetwent secondreparative TE, 5 open surgical repair, 3 embolization, 11are still under observation.
PURPOSE: To report our single-center results of abdominal aortic aneurysm (AAA) repair by transluminal endografting (TE).
ME71-JODS: ]80 TE were attempted from 3/94-10/99 inaverage to extremely high risk AAA patients, age 53 to
94 yrs, 1J=73±8.2. In each case the TE physician teamcomprised a senior JR, 1 JR fellow, vascular surgeon,surgical asst., anesthesiologist. Epidural anesthesia andbifemoral access were used in almost all cases. Followup included Hx, PE, spiral CT. Data sources werecharts, case report forms, and since 1/96, computerizedmedical records. Fifteen TE procedures were performedfrom 3/94 to 12/95. Office consults from 1/96-10/99 included 392 AAA patients: 360 (91.8%)M; 32 (8.2%)F.Overall 1581.360 (43.9%) men, but only 7/32 (21.9%)women undetwent TE. Most exclusions in women weredue to small iliacs. The other 227/392 had open surgeryor are under observation for smaller AAAs. TE deviceswere home-made, n=9; EVT (Guidant), n=62; Talent(Medtronic-World Medica!), n=55; Vanguard (BostonScientific), n=29, Excluder (W.L. Gore & Associates),n=25. Configurations were: bifurcated 88%, tube 6%,and unilateral aortoiliac+cross-femoral graft 6%.
CONCLUSION TE is a safe, effective treatment for AAA,even in high-risk patients. LOS is short. Endoleak prevention and management are among the greatest challenges we face today.

FEATURED ABSTRACTCommentator: James B. Spies, MD
RESULTS: At 3.5 months follow-up, 61 of 65 1'atients(93.8%) reported improvement of the symptoms. Contrast enhanced dynamic MRI revealednon-enhancing ·areas at the previously noted adenomyosis suggesting coagulation necrosis in 44 patients (67.7%), decreased size of adenomyosis in 17patients (26.1%), and no change of adenomyosis in4 patients (6.2%). 6 patients (mean age; 45.2 years,age range; 40-53 years) b~came amenorrheic.
CONCLUSION Particulate transcatheter uterine arterial embolization is an effective therapy for the treatment of symptomatic adenomyosis and may be avaluable alternative to hysterectomy, or other surgical procedures. Further investigation is warranted.
