PurposeTo review safety and efficacy of bronchial artery embolization (BAE) for treatment of hemoptysis in adult patients with cystic fibrosis (CF) and to report 30-day, 1-year, and 3-year outcomes.Materials and MethodsBetween January 2001 and April 2018, 242 patients with CF were evaluated for hemoptysis. Thirty-eight BAEs were performed in 28 patients with hemoptysis. Technical success was defined as freedom from repeat embolization and hemoptysis-related mortality. Clinical success was defined as freedom from repeat embolization and mortality from any cause. Technical and clinical success were examined at 30 days, 1 year, and 3 years after initial BAE. Mean patient age was 32 years, and median follow-up was 4.8 years (range, 10 mo to 16.7 y).ResultsTechnical and clinical success rates at 30 days were 89% (25/28) and 82% (23/28), respectively. Success rates at 1 year were 86% (24/28) and 79% (22/28), respectively, and at 3 years were 82% (23/28) and 75% (21/28), respectively. The 30-day overall complication rate was 7.9% (3/38) with 2.6% (1/38) major complication rate and 5.2% (2/38) minor complication rate. Overall 3-year mortality rate was 25% (7/28).ConclusionsBAE is safe and effective in patients with CF presenting with life-threatening hemoptysis. BAE results in high rates of long-term technical and clinical success in this patient population despite progressive chronic disease. Repeat embolization is necessary only in a minority of patients. 相似文献

PurposeTo evaluate the effectiveness and safety of temporary proximal uterine artery embolization (UAE) for the treatment of highly vascularized retained products of conception (RPOCs).Materials and MethodsThis retrospective analysis included women who underwent treatment for vaginal bleeding after abortion, miscarriage, or delivery, with highly vascularized RPOCs detected by Doppler ultrasound (US) (ie, presence of an enhanced myometrial vascularity, a low resistance index of <0.5, and a peak systolic velocity of ≥0.7 m/s). A unilateral or bilateral embolization with torpedoes of gelatin foam was performed. From November 2017 to January 2021, 24 women with a median age of 30 years (interquartile range, 26.0–34.5 years) with symptomatic highly vascularized RPOCs were included. Clinical success was defined as bleeding arrest between the UAE and 1-month follow-up. Technical success was defined as the complete obstruction of at least 1 uterine artery supplying vascular abnormalities. The safety of the procedure according to the classification of the Society of Interventional Radiology and evolution of lesions on US were also reported.ResultsTechnical success was achieved in all 24 (100%) patients, with bilateral arterial embolization in 19 (79%) patients and unilateral embolization in 5 (21%) patients. Clinical success was achieved in all 24 (100%) patients. Five patients still had uterine retention at the 1-month follow-up, including 2 patients with highly vascularized RPOCs. Two patients benefited from hysteroscopy, and 3 had noninvasive management. Four minor adverse events were reported (1 patient had infectious endometritis and 3 patients had a postembolization syndrome).ConclusionsProximal UAE with torpedoes of gelatin foam is safe and effective for the management of symptomatic highly vascularized RPOCs. 相似文献

PurposeTo assess ischemic adverse events following particle embolization when used as a second-line embolic to coil embolization for the treatment of acute lower gastrointestinal bleeding (LGIB).Materials and MethodsThe single-institution retrospective study examined 154 procedures where embolization was attempted for LGIB. In 122 patients (64 men; mean age, 69.9 years), embolization was successfully performed using microcoils in 73 procedures, particles in 34 procedures, and both microcoils and particles in 27 procedures. Particles were used as second-line only when coil embolization was infeasible or inadequate. Technical success was defined as angiographic cessation of active extravasation after embolization. Clinical success was defined as the absence of recurrent bleeding within 30 days of embolization.ResultsTechnical success for embolization of LGIB was achieved in 87% of the cases (134/154); clinical success rate was 76.1% (102/134) among the technically successful cases. Clinical success was 82.2% (60/73) for coils alone and 68.9% (42/61) for particles with or without coils. Severe adverse events involving embolization-induced bowel ischemia occurred in 3 of 56 (5.3%) patients who underwent particle embolization with or without coils versus zero of 66 patients when coils alone were used (P = .09). In patients who had colonoscopy or bowel resection within 2 weeks of embolization, ischemic findings attributable to the procedure were found in 3 of the 15 who underwent embolization with coils alone versus 8 of 18 who underwent embolization with particles with or without coils (P = .27).ConclusionsParticle embolization for the treatment of LGIB as second-line to coil embolization was associated with a 68.9% clinical success rate and a 5.3% rate of ischemia-related adverse events. 相似文献

PurposeTo identify risk factors for clinical failure of uterine artery embolization (UAE) for postpartum hemorrhage (PPH), with particular attention to the uterine artery diameter.Materials and MethodsThis retrospective study included 47 patients who underwent UAE for PPH between January 1, 2010, and January 31, 2021. Technical success was defined as the completion of embolization of the arteries thought to be the cause of the bleeding. Clinical success was defined as no recurrent bleeding or need for additional therapeutic interventions. Univariate and multivariate analyses were performed to examine the risk factors associated with clinical failure of UAE.ResultsOf the 47 patients, 6 had recurrent bleeding. Of the 6 patients, 4 underwent hysterectomy, and 2 underwent repeat embolization. The clinical success rate was 87.2% (41/47), with no major adverse events such as uterine infarction or death. In univariate analysis, there were slight differences in multiparity (P = .115) and placental abruption (P = .128) and a significant difference in the findings of a narrow uterine artery on digital subtraction angiography (DSA) (P = .005). In multivariate analysis, only a narrow uterine artery on DSA was a significant factor (odds ratio, 18.5; 95% confidence interval, 2.5–134.8; P = .004).ConclusionsA narrow uterine artery on DSA was a risk factor for clinically unsuccessful UAE for PPH. It may be prudent to conclude the procedure only after it is ensured that vasospasm has been relieved. 相似文献

PurposeTo evaluate the safety and efficacy of outpatient transarterial embolization for symptomatic refractory internal hemorrhoids.Materials and MethodsRetrospective analysis of 134 patients who underwent hemorrhoidal artery embolization (HAE) for symptomatic internal hemorrhoids between August 2021 and June 2022 (76 men and 58 women) was performed. The mean age was 54.9 years, with a mean Goligher hemorrhoid grade (HG) of 2.1. Branches of the superior rectal artery (SRA) or middle rectal artery supplying the corpus cavernosum recti were embolized with both spherical particles and microcoils. Standard-of-care evaluations were performed at baseline and the 1 month follow-up, which included hemorrhoid-related pain (HRP) (0–10), hemorrhoid symptoms score (HSS) (5–20), quality of life (QoL) (0–4), French bleeding score (FBS) (0–9), and HG (0–4). Clinical success was defined as improvement of symptoms without additional treatment.ResultsEmbolization of at least 1 hemorrhoidal artery was achieved in 133 (99%) of the 134 patients. The mean number of SRA branches embolized per patient was 2.9 ± 1.0. Clinical success was seen in 93% (124 of 134) of patients at the 1-month follow-up, with 10 patients requiring repeat embolization. There were significant improvements in all mean outcomes at 1 month: HSS (11–7.8; P < .01), HRP (4.1–1.3; P < .01), QoL (2.2–0.8; P < .01), FBS (4.4–2.2; P < .01), and HG (2.3–1.2; P < .05). There were no severe adverse events.ConclusionsHAE is a safe and effective outpatient treatment for refractory symptomatic internal hemorrhoids in the short term. 相似文献

This is a single-center retrospective analysis of 3 patients (mean age, 61 y ± 8.6) who underwent repeat prostatic artery (PA) embolization (PAE; rPAE) because of clinical failure after PAE. Revascularization of the central gland through a recanalized PA was the most frequent pattern observed (5 of 7; 71.4%), followed by revascularization through penile collateral vessels (2 of 7; 28.6%). Technical success during rPAE was achieved in 5 hemiprostates (83.3%). Clinical success at 6 months after rPAE was achieved in 2 of 3 patients (66.6%). Implications of these findings could be valuable to those performing PAE. 相似文献

PurposeTo evaluate the efficacy and safety of embolization of hyperemic synovial tissue for the treatment of knee pain secondary to osteoarthritis (OA).Materials and MethodsTwenty patients with radiographic knee OA and moderate-to-severe pain refractory to conservative therapy were enrolled in a prospective, 2-site pilot study. Genicular artery embolization (GAE) was performed with 75- or 100-μm spherical particles. Patients were assessed with magnetic resonance imaging at baseline and at 1 month and with the Visual Analogue Scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at baseline and at 1, 3, and 6 months. Adverse events were recorded at all timepoints.ResultsEmbolization of at least 1 genicular artery was achieved in 20/20 (100%) patients. Mean VAS improved from 76 mm ± 14 at baseline to 29 mm ± 27 at 6-month follow-up (P < .01). Mean WOMAC score improved from 61 ± 12 at baseline to 29 ± 27 at 6-month follow-up (P < .01). Self-limiting skin discoloration occurred in 13/20 (65%) patients. Two of 20 (10%) patients developed plantar sensory paresthesia that resolved within 14 days.ConclusionsGAE to treat knee pain secondary to OA can be performed safely and demonstrates potential efficacy. Further randomized comparative studies are needed to determine true treatment effect versus placebo effect. 相似文献

PurposeTo evaluate the safety and efficacy of repeat prostatic artery (PA) embolization (PAE) for benign prostatic hyperplasia (BPH).Materials and MethodsA single-center retrospective study was conducted from 2009 to 2018 in 108 patients with symptomatic BPH treated with repeat PAE: group A (n = 39; 36.1%) were patients who never showed a response to PAE, and group B (n = 69; 63.9%) were patients who had clinical improvement in the first 6 months following PAE but relapsing symptoms afterward. The main patterns of revascularization were 75% from the previously embolized PA and 25% from collateral vessels (superior vesical, posterior-lateral PA, penile branches). Technical outcomes and adverse events were registered. International Prostate Symptom Score (IPSS), quality of life (QOL), and clinical success were compared between groups.ResultsMedian follow-up was 18 months (range, 1–36 mo); median interval between PAE and repeat PAE was 420 days (range, 77–2,240 d). Mean procedural time was significantly longer for repeat PAE vs initial PAE (81.1 min vs 67.4 min; P = .0007). There were no major complications and no urinary incontinence. Mean IPSS/QOL improvements were greater in group B vs group A: 9.51 vs 6.13 and 1.30 vs 0.56, respectively (P < .001). The cumulative probability of clinical success after repeat PAE was higher in group B than in group A (P = .0001): 84.1% vs 46.2% at 1 month, 56.7% vs 28.2% at 12 months, and 51.9% vs 16.9% at 24–36 months.ConclusionsRepeat PAE is safe and effective for recurrence of lower urinary tract symptoms caused by BPH but has limited impact in patients who did not show a response to initial PAE. 相似文献

PurposeTo investigate the safety and efficacy of an aqueous polyethylene glycol-based liquid embolic agent, Embrace Hydrogel Embolic System (HES), in the treatment of benign and malignant hypervascular tumors.Materials and MethodsA prospective, single-arm, multicenter study included 8 patients, 5 males and 3 females, with a median age of 58.5 years (30–85 years), who underwent embolization in 8 tumors between October 2019 and May 2020. Technical success was defined as successful delivery of HES to the index vessel, with disappearance of >90% of the targeted vascular enhancement or, for portal vein embolization, occlusion of the portal branches to the liver segments for future resection. The volume of HES administered, ease of use (5 point Likert scale), administration time, and adverse events (AEs) were recorded. Evaluation was performed at 7, 30, and 90 days via clinical assessment and blood testing, and follow-up imaging was performed at 30 days.ResultsEight patients were enrolled, and 10 embolizations were performed in 8 lesions. Tumors included hepatocellular carcinoma (n = 4), renal angiomyolipoma (n = 3), and intrahepatic cholangiocarcinoma (n = 1). Technical success was 100%, and the average ease of use was 3.3 ± 1.0 SD. The HES delivery time was 1–28 minutes (median, 16.5 minutes), and the HES volume injected was 0.4–4.0 mL (median, 1.3 mL). All patients reached 30-day follow-up with imaging, and 6 patients reached 90-day follow-up. There were 3 serious AEs in 2 patients that were unrelated to the embolic agent.ConclusionHES resulted in a 100% embolization technical success rate. The product ease of use was acceptable, and no target vessel recanalization was noted on follow-up imaging at 30 days. 相似文献

PurposeTo report the safety and efficacy of the embolization of splenic artery aneurysms (SAAs) with coils plus ethylene vinyl alcohol copolymer (EVOH) agent.Materials and MethodsA single-center retrospective study was conducted from 2016 to 2019 to collect SAAs. Twelve asymptomatic patients (mean age, 59 years) with 15 SAAs (mean size, 23.6 mm; size range, 15–40 mm) were treated with embolization. Embolization was performed with EVOH (Squid 8/34) and fibered detachable coils. Transfemoral embolization was performed with a microcatheter to achieve a splenic artery occlusion embolizing the SAA and its efferent and afferent branches. Follow-up was based on color Doppler ultrasound at 24 hours and on computed tomography (CT) angiography at 1 (n = 12) and 6 months (n = 12) after embolization. Mean number of coils and Squid vials used for each patient, major/minor complications, technical success, 30-day clinical success, cases of revascularization/reintervention, and mortality were assessed. Technical success was defined as complete exclusion of the aneurysmal segment and cessation of blood flow into the sac. Clinical success at 1 month was based on the absence of clinical symptoms and the exclusion of aneurysm revascularization on CT angiography.ResultsThe mean number of coils and Squid vials was 5.75 (standard deviation [SD], 1.58; range, 3–9) and 1.41 (SD, 0.49; range, 1–2), respectively. Both technical and 30-day clinical success were 100%, with no cases of aneurysm revascularization (CT angiography performed in all patients at 1 month and 6 months and in 3 patients at 24 months). No major complications or fatal events were recorded. In terms of minor complications, 2 cases of mild pancreatitis (transient amylases increase) and 1 case of focal splenic ischemia without clinical sequelae were recorded.ConclusionsEmbolization in SAAs using coils plus EVOH was safe and effective without SAA revascularization 相似文献

PurposeTo evaluate the safety, efficacy, and clinical impact of preoperative cone-beam computed tomography (CT)–guided selective embolization of endophytic renal tumors with the fluorescent dye indocyanine green (ICG) and ethiodized oil in patients undergoing robot-assisted partial nephrectomy (RAPN) using near-infrared fluorescence imaging (NIR-FI).Materials and MethodsPatients with renal endophytic tumors eligible for RAPN and transarterial embolization with ICG and ethiodized oil were prospectively enrolled. Technical success was defined as the completion of the embolization procedure. Radiographic success, defined as ethiodized oil accumulation in the nodule, was classified as poor, moderate, good, or optimal on the basis of postembolization cone-beam CT. Surgical visibility of the tumors during RAPN with the use of NIR-FI was classified as follows: (a) not visible, (b) visible with poorly defined margins, and (c) visible with well-defined margins.ResultsForty-one patients underwent preoperative selective embolization. Technical success was 100%. Ethiodized oil accumulation on cone-beam CT was poor in 2 (4.9%), moderate in 6 (14.6%), good in 25 (61.0%), and optimal in 8 (19.5%) of 41 patients. During RAPN with NIR-FI, tumors were visible with well-defined margins in 26 (63.4%), visible with blurred margins in 14 (34.1%), and not visible in 1 (2.4%) of 41 cases. There were no adverse events following endovascular embolization.ConclusionsPreoperative transarterial superselective embolization of endophytic renal tumors with ICG and ethodized oil in patients undergoing RAPN is safe and effective, allowing accurate intraoperative visualization and resection of endophytic tumors. 相似文献

PurposeTo evaluate the feasibility, safety, and effectiveness of N-butyl cyanoacrylate (NBCA) embolization for the treatment of aortic dissection.Materials and MethodsIn this single-center retrospective study conducted from February 2003 to June 2019, NBCA embolization of an aortic false lumen was attempted in 12 patients (median age, 59 y; range, 41–68 y) and thoracic endovascular aortic repair (TEVAR) was performed in 53 patients (median age, 59 y; range, 37–70 y) for aortic dissection with one or more indications of persisting pain, malperfusion, rupture or impending rupture, maximal aortic diameter ≥ 55 mm, and/or rapid aortic enlargement. The main exclusion criterion for embolization was the presence of fast blood flow in the aortic false lumen on aortography. The efficacy of NBCA embolization and TEVAR was compared by evaluating technical and clinical outcomes, repeat intervention–free survival (RFS), and overall survival (OS).ResultsTechnical success was achieved in 11 of the 12 patients treated with NBCA embolization (91.7%), and clinical success was achieved in 9 of these 11 (81.8%). No significant difference was found between embolization and TEVAR in clinical success rates (embolization, 81.8%; TEVAR, 84.9%; P = .409) or procedure-related complications (embolization, 1 patient [8.3%]; TEVAR, 4 patients [7.5%]; P = .701). In addition, embolization showed comparable 5-y RFS (embolization, 82.5% ± 9.3; TEVAR, 85.5% ± 4.8; P = .641) and 5-y OS (embolization, 100%; TEVAR, 95.4% ± 3.2; P = .744) rates to TEVAR.ConclusionsNBCA embolization of the false lumen in aortic dissection seems to be a safe and effective treatment modality for the closure of false lumen in selected patients. 相似文献

Ten patients with painful early-stage knee osteoarthritis underwent transcatheter arterial embolization of neoangiogenic branches from genicular arteries. At 12 months, 6 patients had responded to treatment according to study criteria. Median pain, function, and quality-of-life scores had improved by 15.4%, 21.3%, and 100%, respectively, for the 10 patients. Median 30-second chair stand test and 6-minute walk test scores had improved by 43% and 26%, respectively. No major adverse events occurred. Improvements following transcatheter arterial embolization provide evidence that embolization might be an effective treatment technique for people with early-stage knee osteoarthritis, although more rigorous evaluation is required. 相似文献

PurposeTo determine the value of preprocedural MR imaging in genicular artery embolization (GAE) for patients with osteoarthritic knee pain.Materials and MethodsThis single-center study retrospectively analyzed 28 knees in 18 patients who underwent GAE for intractable knee pain < 1 month after MR imaging. The pain experienced in each knee was evaluated on a 100-mm visual analog scale (VAS) at baseline and 1- and 3-month after GAE. “GAE responders” were defined as knees that exhibited greater than 30% reduction of VAS pain scores from baseline at both follow-up visits. Musculoskeletal radiologists evaluated MR images of the affected knee compartment regarding cartilage defects, osteophytes, subchondral cysts, bone marrow lesions (BMLs), meniscal injury, and joint effusion. The performances of Kellgren–Lawrence (KL) grading and MR findings in predicting GAE responders was estimated based on receiver operating characteristic curves.ResultsThe mean VAS pain score was 84.3 mm. BML (area under the curve [AUC], 0.860; P < .001), meniscal injury (AUC, 0.811; P = .003), and KL grading (AUC, 0.898; P < .001) were significantly associated with GAE outcome. To predict GAE responders, KL grade ≤ 2 yielded a sensitivity of 87.5% and a specificity of 60.9%, BML grade ≤ 1 yielded a sensitivity of 75.0% and a specificity of 69.6%, and meniscal injury grade ≤ 2 yielded a sensitivity of 83.3% and a specificity of 72.7%.ConclusionsLarge BMLs and severe meniscal injuries on MR imaging, as well as high KL grades, indicated poor responses to GAE. 相似文献

PurposeTo review and indirectly compare the outcomes of genicular artery embolization (GAE), radiofrequency (RF) ablation, and intra-articular (IA) injection for the treatment of knee pain secondary to osteoarthritis (OA).Materials and MethodsA literature review of the MEDLINE and Cochrane databases was conducted with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement in June 2020. The visual analog scale (VAS) was recorded at baseline and at all available time points for each therapy. Standard mean differences were calculated at each time point and compared between treatments to assess the magnitude of the treatment effect.ResultsAll 3 treatments demonstrated significant differences in VAS scores after therapy. RF ablation produced the greatest significant mean reduction in relative VAS score from baseline at 1 year of follow-up (mean, 0.49; 95% confidence interval, 0.4–0.59; P = .03). GAE reported the most significant reductions in VAS scores across all measured time points. Overall, the comparison did not demonstrate a significant difference in VAS scores among patients receiving IA injections, RF ablation, and GAE.ConclusionsThe current evidence does not suggest a significant difference in outcomes among IA injection, RF ablation, and GAE for knee pain secondary to OA. 相似文献

PurposeTo evaluate the short-term outcomes of genicular artery embolization (GAE) for knee osteoarthritis (OA) with and without bone marrow lesion (BML) and/or subchondral insufficiency fracture of the knee (SIFK).Materials and MethodsThis single-institution prospective observational pilot study analyzed 24 knees in 22 patients with mild to moderate knee OA, including 8 knees without BML, 13 knees with BML, and 3 knees with both BML and SIFK. The area and volume of BMLs on magnetic resonance images were measured before and after GAE. Baseline and postoperative pain and physical function were assessed using the visual analog scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).ResultsGAE significantly reduced the BML area and volume 3 months after embolization in the knees with BML (both P < .0005). GAE significantly decreased the VAS scores at 3 and 6 months after embolization in patients without BML (both P = .04) and those with BML (both P = .01). GAE also lowered the WOMAC scores 3 months after embolization in patients without and with BML (P = .02 and P = .0002, respectively). However, GAE did not significantly alter the BML area and volume (both P = .25), VAS scores (P = 1.00), and WOMAC scores (P = .08) in patients with BML and SIFK at 3 months after GAE.ConclusionsThis observational pilot study suggested that GAE effectively reduces the BML area and volume and improves pain and physical function in patients with knee OA accompanied by BML but is inefficacious in those with both BML and SIFK. 相似文献

PurposeTo evaluate the efficacy and safety of transcatheter arterial embolization (TAE) for the treatment of chronic inflammatory joint pain via systematic review and meta-analysis.Materials and MethodsMEDLINE and EMBASE databases were searched for studies reporting outcomes in patients with chronic inflammatory joint pain treated with TAE. Meta-analyses of pain score changes, changes in proportions of patients on analgesic medications, range of motion changes, technical success rates, and adverse events rates were performed. Subgroup analyses were conducted with respect to pain site (knee versus shoulder).ResultsFourteen observational studies, which included 346 patients, were reviewed. The pooled technical success rate was 95.8%, and no major adverse events were observed. The pooled mean difference in pain score at 1 week was 3.1. At 1, 3, and 6 months, the difference in score was 4.0, 4.2, and 5.1, respectively. At 1 year, the difference was 5.5. Subgroup analysis demonstrated that shoulder embolization was associated with greater reduction of pain than knee embolization at 3 and 6 months (P < .001 and P = .018, respectively), whereas there was no significant difference between the sites at 1 month (P = .734). The pooled proportions of patients on analgesic medication at baseline and at 1, 3, 6, and 12 months were 81.1%, 36.3%, 42.3%, 28.2%, and 22.4%, respectively. The pooled estimated increase in the range of motion among patients who underwent shoulder embolization was 55.6° for anterior elevation and 64.7° for abduction.ConclusionsTAE is an effective and safe therapeutic option for patients with chronic inflammatory joint pain. 相似文献

PurposeTo evaluate technical success, efficacy and safety of portomesenteric venous (PMV) intervention for PMV stenosis or occlusion following nontransplant hepatobiliary or pancreatic (HPB) surgery.Materials and MethodsA retrospective review identified 42 patients (mean age 60 y) with PMV stenosis (n = 33; 79%) or occlusion (n = 9; 21%) who underwent attempted PMV intervention following HPB surgery between June 1, 2011, and April 1, 2018. Main outcomes were technical success, primary patency rates, and complications. Technical success was compared by venous pathology and primary PMV patency based on anticoagulation status after the procedure using Fisher exact test. Rates of primary patency by stent group were estimated using Kaplan-Meier method.ResultsTechnical success was 91% (n = 38/42) and significantly higher in patients with stenosis (n = 33/33; 100%) vs occlusion (n = 5/9; 56%) (P = .001). Primary presenting symptom resolved in 28 (87%) patients, including 6 (100%) patients with gastrointestinal bleeding. At mean imaging follow-up of 8.6 months ± 8.8, primary stent patency was 76%. There was no significant difference in primary stent patency based on anticoagulation status after the procedure (P = .48). There were 2 (4.8%) periprocedural complications.ConclusionsPortomesenteric venoplasty and stent placement following nontransplant HPB surgery is safe with a high rate of technical success if performed before chronic occlusion. 相似文献

PurposeTo evaluate the efficacy and safety of transvenous coil embolization of the venous sac for type II renal arteriovenous malformation (AVM).Materials and MethodsA retrospective review was conducted of 8 patients (5 women and 3 men; mean age, 57 years; age range, 41–69 years) who underwent transvenous coil embolization for type II congenital renal AVM at 5 different hospitals between 2012 and 2018. Additional intra-arterial ethanol injection was performed if shunt flow persisted after venous sac coiling. Technical success was defined as complete occlusion of shunt flow with coil embolization. Clinical success was defined as no symptom recurrence during the follow-up period. The renal parenchymal infarction rate was measured on computed tomography (CT), and procedure-related complications were reviewed.ResultsNine sessions of embolization were performed for 8 patients. The mean venous sac size was 24 mm (range, 10–39 mm), and a mean of 14 micro and/or micro-detachable coils (range, 3–50) were used. The technical success rate was 88% (7 of 8) using coil embolization. One patient (12%) required additional ethanol injection to complete occlusion of the shunt flow and had a less than 10% parenchymal infarction on follow-up CT. No procedure-related complications or recurrences occurred during a mean clinical follow-up period of 20.8 months (range, 4.7–76.6 months).ConclusionsTransvenous coil embolization of type II renal AVM showed an 88% technical success rate. One patient (12%) showed less than 10% renal parenchymal infarction after additional ethanol injection. No additional complications or recurrences occurred during the follow-up period. 相似文献
