The aims of the present study were to (1) analyse preoperative computed tomography (CT) parameters, (2) investigate whether obesity and CT parameters affect surgical outcomes in patients undergoing LESS lateral retroperitoneal adrenalectomy, and (3) further establish the optimal cutoff point of CT parameters for tolerable operating time. Between January 2010 and August 2016, patients who underwent LESS adrenalectomy through the retroperitoneal approach in our hospitals were included. Patients’ demographic data, preoperatively measured CT parameters (the depth and horizontal width to the adrenal gland in the axial view of abdominal CT, the vertical height in the coronal view of CT, and the angle of the depth and horizontal width), and intraoperative (operative time and blood loss) and postoperative (hospital stay and complications) parameters were retrospectively reviewed. Linear regression was performed to determine factors that potentially affect surgical outcomes. In 116 patients, depth was the only CT parameter associated with surgical outcomes. Large depth (P = 0.005; 95% CI 1.739–9.256) and high BMI (P = 0.012; 95% CI 0.357–2.851) were factors significantly associated with longer operative time. The area under the ROC curve for the depth was 0.69 (P = 0.002), and the cutoff point 10.48 cm may be the tolerable operating time. Our results suggest a depth limit of 10.48 cm for the optimal prediction of operating time less than 90 min; although obese patients and deeper adrenal glands had longer operative time, LESS adrenalectomy could be performed in the obese patients without increased blood loss, prolonged hospital stay, or increased pain.

Background This study investigated the impact of post-radiation sinusitis on the prognosis of nasopharyngeal carcinoma (NPC) patients treated with intensity-modulated radiation therapy (IMRT). Methods Two hundred and thirty patients with non-metastatic NPC were analyzed in terms of freedom from local failure (FFLF), freedom from distant failure (FFDF), overall survival (OS), and disease-free survival (DFS). For each patient, the status of the sinus mucosa was flexibly assessed by documenting mucosal changes as indicated by differences between images obtained before radiotherapy and more than 6 months post-radiation. Results With a median follow-up of 39.7 months (8 to 81 months), 19 (8.26%) patients relapsed locally, 13 (5.65%) patients failed in the neck, and 26 (11.3%) patients developed distant metastases. The presence of sinusitis noted in images post-radiation was a significant predictor for DFS (p = 0.001), FFLF (p = 0.004), and FFDF (p = 0.015), in addition to having high negative predictive value for local relapse (97.5%). Conclusions This is the first study to investigate the prognostic value of post-radiation sinusitis in NPC patients treated with IMRT. Post-radiation sinusitis was found to be a significant predictor for DFS, FFLF, and FFDF, and was also found to have high negative predictive value for local recurrence (97.5%). It may thus be used as an additional tool for clinicians to determine the possibility of recurrence.

Objectives To investigate the prognostic significance of sarcopenic cachexia compared to sarcopenia without cachexia in the outcomes of upper urinary tract urothelial carcinoma (UTUC) patients treated with radical nephroureterectomy (RNU). Materials and methods Between 2011 and 2016, 163 patients with UTUC who received RNU at a tertiary medical center were included. Pre-operatively clinical data, history, and abdominal computer tomography scans were analyzed retrospectively. The diagnosis of sarcopenia was based on abdominal computed tomography data on the patient’s skeletal muscles. Outcomes of relapse-free, cancer-specific, and overall survival were analyzed by multivariate Cox regression. Results After adjusting for age, sex, pre-operatively estimated glomerular filtration rate, body mass index, underlying diseases, tumor grade, and tumor stage, cachexia was a significant poor prognostic factor for relapse-free survival (hazard ratio [HR]: 18.5, 95% confidence interval [CI]: 2.87–118, p = 0.002) and cancer-specific survival (HR: 26.6, 95% CI: 4.04–175, p = 0.001). In contrast, sarcopenia without cachexia was not a significant predictor of cancer outcomes. Conclusions To date, this is the first study to investigate the effect of cachexia among sarcopenic patients with UTUC treated with RNU. We identified the prognostic significance of cachexia on outcomes. Indeed, when UTUC is treated with RNU, we should evaluate not only sarcopenia status but also cachexia. The low survival rate among patients with UTUC complicated with cachexia deserves attention.

Background. Vascular calcification is common and associated with unfavorable outcomes among patients with end-stage renal disease (ESRD). Nevertheless, little is known whether the progression of vascular calcification outweighs the baseline calcification in association with overall and cardiovascular (CV) mortality in hemodialysis (HD) patients. Methods. This study included 140 maintenance HD patients. Vascular calcification was assessed using the aortic arch calcification (AoAC) score measured from chest radiographs at the baseline and the second year of follow-up. Progression of vascular calcification (ΔAoAC) was defined as the difference between the two measurements of AoAC. The association of ΔAoAC with overall and CV mortality was evaluated using multivariate Cox regression analysis. Results. During the mean follow-up period of 5.8 years, there were 49 (35%) overall mortality and 27 (19.3%) CV mortality. High brachial-ankle pulse wave velocity was positively correlated with ΔAoAC, whereas old age was negatively correlated with ΔAoAC. In multivariate adjusted Cox analysis, increased ΔAoAC (per 1 unit), but not baseline AoAC, was significantly associated with overall mortality (HR, 1.183; 95% CI, 1.056–1.327; p=0.004) and CV mortality (HR, 1.194; 95% CI, 1.019–1.398; p=0.028). Conclusion. Progression of AoAC outperformed the baseline AoAC in association with increased risk of overall and CV mortality in HD patients. A regular follow-up of chest radiograph and AoAC score assessments are simple and cost-effective to identify the high-risk individuals of unfavorable outcomes in maintenance HD patients.

To share our multicenter experience using a safe and effective method for treating large proximal ure-teral calculus by simultaneous supine percutaneous nephrolithotomy (sPCNL) and retrograde ureterolithotripsy (URSL) in the Galdakao-modified supine Valdivia position.Between December 2014 and August 2017, all patients with large proximal ureteral stones (15 mm) who underwent simultaneous sPCNL and retrograde URSL at three medical centers were retro-spectively reported. The ureter stone was pushed back (retrograde) with the ureteroscope and was retrieved using forceps with a nephroscope through an Amplatz sheath. Surgical methods and outcomes were described to improve our experience and management of large proximal ureteral calculi.A total of 31 patients underwent simultaneous sPCNL and retrograde URSL. The mean patient age, stone size, operating time, and postoperative hospital stay were 57 years (range, 32-74 years), 20.1 mm (range, 15.0-37.9 mm), 81 minutes (range, 30-150), and 3.2 days (range, 2-7 days), respectively. There were 10 modified Clavien grade I and five grade II complications. No blood transfusions were necessary in this series. All patients were treated with double-J stents without a nephrostomy tube. Only one patient did not achieve stone-free status because of the strict stone impaction into the ureteral wall. This patient received auxiliary URSL after two months. Thereafter, the overall stone-clearance rate at three months was 100%.Our preliminary data showed that this modified method is safe and effective for treating large prox-imal ureteral stones.

To investigate the added value of diffusion-weighted imaging (DWI) when used with conventional T2-weighted magnetic resonance (MR) imaging (T2WI) and MR cholangiopancreatography (MRCP) for diagnosing bile duct dilatations. Our institutional review board approved this retrospective study protocol and waived the informed consent requirement. The study included 151 consecutive patients (70 men, 81 women) with intra- and/or extra-hepatic bile duct dilatation examined using MR imaging. Two radiologists independently and randomly reviewed 3 image sets (A: MRCP and T2WI; B: DWI; and C: combined T2WI, MRCP, and DWI) at different occasions to differentiate between malignancy, biliary lithiasis, and benign dilatation. The sensitivity, specificity, and diagnostic accuracy of these imaging sets were calculated and compared. For both readers, combined T2WI, MRCP, and DWI exhibited significantly higher sensitivity and diagnostic accuracy for malignant dilatation, compared with conventional T2WI and MRCP (P

The purpose of this study is to evaluate the image quality of split-bolus portal venous phase urography and the potential reduction of radiation dose by using a second-generation dual-source dual-energy CT (DECT) scanner.DECT urography was performed in 84 patients. Unenhanced CT was performed 20 minutes after drinking 800 mL of water. The split-bolus protocol consisted of a sequence of injections, as follows: 200 mL of normal saline (2.0 mL/s), 50 mL of contrast medium (2.5 mL/s) at 0 second, 70 mL of contrast medium (2.5 mL/s) at 360 seconds, and a saline flush of 25 mL. The scan was started at 420 seconds. Virtual unenhanced images were reconstructed from contrast-enhanced images. The mean CT density and signal-to-noise ratio (SNR) of the renal parenchyma, vessels, upper urinary tract, normal reference tissues, and tumors were measured for image quantitative analysis. Image quality and opacification of the collecting systems were rated by two radiologists using 3- or 4-point scales.The SNR of all measured sites, except the renal pelvis, showed a statistically significant correlation (p0.001) between the true unenhanced and virtual unenhanced images. The overall sensitivity of stone detection was 87.5% (28/32) in virtual unenhanced images. Image quality of the renal parenchyma, arteries, and veins was excellent in 59.5%, 75.0%, and 97.6% of cases, respectively. Opacification of the intrarenal collecting systems, proximal, middle, and distal ureters, and bladder was complete in 92.9%, 83.9%, 78.6%, 77.4%, and 26.2% of patients, respectively. Omitting the unenhanced scan can reduce the mean radiation dose from 15.6 to 6.7 mSv.Portal venous phase split-bolus DECT urography provides sufficient image quality with potential to reduce radiation exposure.

To assess the diagnostic accuracy, cancer staging, image quality, and radiation dose of 80-kVp computed tomography (CT) images for patients with colorectal cancers (CRCs) using sinogram-affirmed iterative reconstruction (SAFIRE).Sixty-four consecutive patients (mean weight 62.5 ± 11.3 kg, mean BMI 24.1 ± 3.3 kg/m(2)) with known CRC underwent dual-energy CT. Data were reconstructed as a weighted average (WA) 120-kVp dataset. Both filtered back projection (FBP) and SAFIRE were applied to reconstruct the WA 120-Kvp (Protocol A, B) and 80-kVp (Protocol C, D) image sets. The image noise, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) of the cancers, the normal reference tissues, and the effective dose for each protocol were assessed. The cancer detection, staging, and image quality were evaluated. Analysis of variance was used for statistical analysis.Compared with the FBP datasets at WA 120-kVp (Protocol A) and 80-kVp (Protocol C), the SAFIRE-reconstructed images (Protocols B, D) demonstrated significantly lower image noise (P 0.0083). Protocol D yielded significantly higher CNRs and SNRs for the CRCs and normal reference tissues than did Protocols A and C (P 0.0083). Protocol D also exhibited a significantly higher CNR for the CRC and some normal reference tissues than did Protocol B (P 0.0083). For hypovascular liver metastases (n = 10), Protocol D yielded better SNRs and significantly higher CNRs than did Protocol A (P 0.0083). Overall, accuracy for tumor staging and liver metastasis was 95.3% (61/64) and 100%, respectively, in all of the 4 protocols. The mean effective dose decreased 41% from the WA 120-kVp to the 80-kVp protocols (6.23 vs. 3.68 mSv).The 80-kVp technique with SAFIRE provided high SNR, high CNR, and good accuracy for staging in nonobese patients with CRC. Our study results should be extrapolated to patient populations with a high BMI with caution. Further studies of high BMI patients are therefore warranted.

Peripheral artery occlusive disease and vascular calcification are highly prevalent in hemodialysis (HD) patients, however the association of the combination of ankle-brachial index (ABI) and aortic arch calcification (AoAC) with clinical outcomes in patients undergoing HD is unknown. In this study, we investigated whether the combination of ABI and AoAC is independently associated with overall and cardiovascular mortality in HD patients. The median follow-up period was 5.7 years. Calcification of the aortic arch was assessed by chest X-ray. Forty-seven patients died including 24 due to cardiovascular causes during the follow-up period. The study patients were stratified into four groups according to an ABI 4 or ≤4 according to receiver operating characteristic curve. Those with an ABI 4 (vs. ABI ≥ 0.95 and AoAC score ≤ 4) were associated with overall (hazard ratio [HR], 4.913; 95% confidence interval [CI], 1.932 to 12.497; p = 0.001) and cardiovascular (HR, 3.531; 95% CI, 1.070 to 11.652; p = 0.038) mortality in multivariable analysis. The combination of a low ABI and increased AoAC was associated with increased overall and cardiovascular mortality in patients undergoing HD.

Aortic arch calcification (AoAC) is associated with cardiovascular and all-cause mortality in end-stage renal disease population. AoAC can be simply estimated with an AoAC score using plain chest radiography. The objective of this study is to evaluate the association of AoAC with brachial-ankle pulse wave velocity (baPWV) and cardiomegaly in patients who have undergoing hemodialysis (HD). We retrospectively determined AoAC and cardiothoracic ratio (CTR) by chest x-ray in 220 HD patients who underwent the measurement of baPWV. The values of baPWV were measured by an ankle-brachial index-form device. Multiple stepwise logistic regression analysis was used to identify the factors associated with AoAC score >4. Compared patients with AoAC score ≦4, patients with AoAC score >4 had older age, higher prevalence of diabetes and cerebrovascular disease, lower diastolic blood pressure, higher baPWV, higher CTR, higher prevalence of CTR ≧50%, lower total cholesterol, and lower creatinine level. After the multivariate stepwise logistic analysis, old age, cerebrovascular disease, high baPWV (per 100 cm/s, odds ratio [OR] 1.065, 95% confidence interval [CI] 1.003–1.129, P = 0.038), CTR (per 1%, OR 1.116, 95% CI 1.046–1.191, P = 0.001), and low total cholesterol level were independently associated with AoAC score >4. Our study demonstrated AoAC severity was associated with high baPWV and high CTR in patients with HD. Therefore, we suggest that evaluating AoAC on plain chest radiography may be a simple and inexpensive method for detecting arterial stiffness in HD patients.

Summary Objectives To report three cases of emphysematous prostatic abscess (EPA) and review the literature on this rare entity. Methods All relevant articles published in English over the last 50 years (1961–2011) were identified using a MEDLINE search for keywords ‘emphysematous prostatitis' and ‘emphysematous prostatic abscess'. A total of 12 patients were evaluated for their age, race, underlying disease, pathogens, diagnosis tool, treatment options, and clinical outcome. Results EPA is a high mortality disease (25%) and has an association with diabetes mellitus. The most common pathogen in the 12 cases was Klebsiella pneumoniae . Conclusions The mortality of EPA is higher than that of emphysematous cystitis and emphysematous pyelonephritis. Timely recognition and prompt drainage are very important.

The purpose of this study was to report our experience of percutaneous retrieval of dislodged port catheters with concurrent use of pigtail and loop snare catheters. During a 5-year period at our institute (June 2005 to July 2010), a total of 23 dislodged port catheters were retrieved. The interval between port catheter implantation and dislodged catheter retrieval ranged from 43 days to 1,414 days (mean 586.7 days). The time of delayed retrieval ranged from 1 day to 45 days (mean 4.6 days). All dislodged catheters were retrieved with the concurrent use of pigtail and loop snare catheters via femoral venous route. The prevalence of port catheter dislodgement at our institute was 3.4%. All dislodged port catheters were removed successfully with pigtail and loop snare catheters together. No procedure-related complications were encountered, except for transient arrhythmia in two patients, which required no medication. In conclusion, the concurrent use of pigtail and loop snare catheters is a feasible and easy way for percutaneous retrieval of a dislodged central venous port catheter.

Posttraumatic empyema is a rare complication of trauma with an incidence of 1.6–2.4% in trauma patients. However, it is rarely reported in children. We report the case of a 15-year-old boy who was involved in a traffic accident and diagnosed with a pulmonary contusion at a local hospital. Fourteen days after the accident, posttraumatic empyema thoracis and lung abscess developed with clinical presentations of fever, productive cough and right chest pain. He was successfully treated with computed tomography-guided catheter drainage and intravenous cefotaxime. We emphasize that posttraumatic empyema thoracis and lung abscess are very rare in children, and careful follow-up for posttraumatic lung contusion is essential. Image-guided catheter drainage can be an adjunctive tool for treating selected patients, although most complicated cases of post-traumatic empyema thoracis require decortication therapy.

OBJECTIVE. CT angiography and MR angiography are the main techniques for the noninvasive diagnosis of mesenteric ischemia. High clinical suspicion and knowledge of the differential diagnostic possibilities in this clinical setting are essential for the correct interpretation of the scans.CONCLUSION. CT angiography and MR angiography are well suited for the workup of patients when mesenteric ischemia is suspected.

The aim of the study is to evaluate the use of the tumor border in peripheral non-small cell lung cancer (NSCLC) as an indicator of pleural invasion. This retrospective study was performed at a single tertiary center. The analysis of 136 patients with peripheral NSCLC included 101 (74.3%) patients with pathologically proven pleural invasion and 35 (25.7%) patients without pleural invasion. The tumor borders on conventional computed tomography (CT) were classified into 5 types on lung window setting: type 1, S or reverse S border with a blunt angle; type 2, sharp angle; type 3, concave border with a blunt angle; type 4, straight border with a perpendicular angle; and type 5, convex border with a perpendicular or blunt angle. In patients with more than 1 tumor border type, the priority was type 5, 4, 3, 2, and 1. Blunt angle, pleural contact >3 cm, and adjacent pleural thickening were also recorded for comparison with pleural invasion of peripheral tumors. Tumor border types 2 and 5 significantly differed between patients with and without pleural invasion (P = .001 and P 3 cm, or pleural thickening. Tumor border type 5 was a moderate indicator of pleural invasion with positive LR, 5.20; accuracy, 57%; sensitivity, 45%; specificity, 91%; PPV, 94%; and NPV, 36%. Tumor border type 2 was a weak indicator of pleural invasion with positive LR, 0.51; accuracy, 34%; sensitivity, 34%; specificity, 34%; PPV, 60%; and NPV, 15%. Tumor border type 5 has a high PPV and high specificity for predicting pleural invasion by peripheral NSCLC.

We report here an uncommon anterior chest trauma with an unusual fatal penetrating coronary artery injury by pneumatic nail gun with effective perioperative management. While doing upholstery, a 32-year-old male patient accidentally stabbed by a pneumatic nail gun with injury to the anterior chest was brought to the emergency room of our hospital. Persistent chest pain with unstable vital signs and no external injury except for a faint ecchymosis on anterior chest were noted at arrival. Sixty-four-slice computed tomography (CT) scan revealed a foreign body completely embedded in the chest wall penetrating the left ventricle, with the coronary artery also suspected of being involved because of ST-T changes of V2 to V6 on electrocardiography. Three-dimensional reconstructive CT scans showed a penetrating injury to the left anterior descending coronary artery without complete transection. Thereafter, we performed the operation of nail removal with direct repair of coronary artery that was scheduled based on the image findings preoperatively, and the operation was smoothly performed without coronary artery cardiopulmonary bypass and grafting bypass effectively and simply. He was discharged uneventfully 14 days later. Another CT scan was performed which showed patency of repaired coronary artery 3 months later.

Properties of presumed mechanisms controlling photoreceptor alignments are partially defined. A phototropic mechanism normally dominates alignment, but do modest changes in orientations occur with dark patching? Here, new photopic Stiles–Crawford (SCE-I) determinations were made before patching (pre-patch), just after 8-days of dark-patching (post-patch), and 3 days after patch removal (recovery test). We tested at 0, 11 and 22° in the temporal retina of both eyes. Ten eyes of adult subjects were tested. SCE-I peak positions and Stile's parameter ‘rho’ were assessed. Dark-patching effects were small. Observations revealed meaningful corrective alignment overshoots with recovery in the light. Results suggest (1) the presence of multiple weak mechanisms affecting receptor alignments in the dark; (2) the phototropic mechanism to be dominant in the light; (3) the need for multiple test loci to be sampled in such studies, and (4) small changes in the SCE-I in the pupil plane can reflect meaningful events occurring at the retina.

OBJECTIVE. A variety of treatment options exist for aortic coarctation, both surgical and catheter-based. Knowledge of the normal radiologic appearance of these, as well as their typical complications, is essential for interpretation of CT and MR angiographic studies in these patients.CONCLUSION. CT and MR angiography are noninvasive techniques that are well suited to follow patients after coarctation repair.

To assess the impact of integrated parallel acquisition technique (iPAT) on signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), venous contamination, and overall image interpretability for peripheral magnetic resonance (MR) angiography with use of a dedicated phased-array coil system.Three-dimensional contrast material-enhanced conventional MR angiography and iPAT peripheral MR angiography was performed at three stations (pelvis, thigh, calf) in 38 consecutive patients on a 1.5-T high-performance cardiovascular system (conventional MR angiography, n=19; iPAT MR angiography, n=19). A total of 29 vessel segments per patient were analyzed. For each segment, arterial, muscle, and background signal were measured; SNR and CNR were calculated; and repeated-measures analysis of variance was performed. For each of the three stations, the degree of venous contamination and the overall confidence of interpretability were analyzed with use of ordinal logistic regression analysis accounting for correlated outcome data.A total of 1,018 vessel segments were available for analysis (477 with conventional MR angiography, 541 with iPAT MR angiography). Compared with conventional MR angiography, iPAT MR angiography resulted in decreased SNR and CNR in the pelvis and thigh stations but no change in the calf station. The difference in the pelvis was statistically significant (P.007 for SNR and P0.01 for CNR). Venous contamination in the calf station was significantly less on iPAT MR angiography (P.003), with no significant differences in the other stations. The overall confidence of interpretability with iPAT MR angiography was significantly better on the lower station (P.008).iPAT MR angiography leads to reduced SNR and CNR in the pelvis and thigh, but this does not affect interpretability of images obtained at these stations. The temporal gain results in significantly increased interpretability as a result of less venous contamination in the calf station. iPAT MR angiography is superior to conventional MR angiography for peripheral imaging.

The aim of this study was to determine whether magnetic resonance urography without pharmacological (diuretic) stimulation and mechanical compression allows conclusive evaluation of the urinary system in potential renal donors. In 28 consecutive patients magnetic resonance urography (MRU) was performed on a 1.5-T system. Two techniques, rapid acquisition with relaxation enhancement (RARE) and a gadolinium (Gd)-enhanced 3D fast low angle shot (FLASH) sequence were compared in the absence of adjunctive measures. Two reviewers assessed image quality, presence of artifacts and completeness of visualization of the collecting systems and ureters. Among the 53 MR urograms, there was no difference in image quality and presence of artifacts between RARE and Gd-MRU. Despite high image quality, visualization of the urinary collecting system was insufficient. Continuous visualization from the collecting system to the distal ureter was demonstrated bilaterally in only 14% of the RARE and 26% of Gd-enhanced MR urograms, respectively. Overall, Gd-enhanced MRU was superior to the RARE technique in displaying the segments of the urinary collecting system, but this difference was not found to be statistically significant. Neither the RARE technique nor the gadolinium-enhanced MRU technique is accurate enough to allow the evaluation of the collecting system and ureters in potential renal donors in the absence of pharmacological intervention and compression.

Objectives To evaluate the diagnostic accuracy and the potential radiation dose reduction of dual-energy CT (DECT) for tumor (T) staging of colorectal cancer (CRC) using iodine overlay (IO) and virtual nonenhanced (VNE) images. Materials and Methods This retrospective study included 103 consecutive patients who underwent nonenhanced CT and enhanced DECT for preoperative CRC staging. Enhanced weighted-average (WA), IO and VNE images were reconstructed from enhanced 80 kVp and Sn140 kVp scans. Two radiologists assessed image qualities of the true nonenhanced (TNE) and VNE images. For T-staging, another two radiologists independently interpreted all scans in two separate reading sessions: in the first session, only images derived from the single phase DECT acquisition (IO and VNE images) were read. In the second reading session after 30 to 50 (average:42) days, the same assessment was again performed with the TNE and enhanced WA images thereby simulating conventional dual-phase single-energy CT. The tumor node metastasis (TNM) system was used for staging with histopathologic reports as gold standard. Analysis of variance was used for statistical analysis. Results The signal-to-noise ratios (SNRs) of the tumors and normal reference tissues showed significant correlation between the TNE and VNE images (P

Although mycotic infections of the urinary system occur not infrequently, obstruction of the upper urinary tract because of mycetomas or fungus balls is exceedingly rare. Treatment consists of antifungal treatment and appropriate urinary drainage. In cases resistant to treatment with external drainage and chemotherapy, open surgery is typically performed to remove the mycetoma. However, this can also be achieved percutaneously using mechanical thrombectomy devices, as shown in this case of a 4-month-old infant presenting with renal failure due to bilateral obstructing mycetomas.

A 39-year-old female visited our cardiovascular outpatient department with paresthesia and soreness around the right popliteal fossa, where thrill was palpable. There was no history of trauma, apart from her having undergone acupuncture several years previously. An arteriovenous fistula (AVF) was diagnosed by vascular ultrasonography and magnetic resonance imaging. Angiography confirmed the presence of an AVF fed by the medial geniculate artery. Transarterial embolization was performed to close the AVF using coils and tissue adhesive. To the best of our knowledge, acupuncture-induced AVF has not been previously reported. We present a case demonstrating the merits of percutaneous endovascular intervention for treating this rare complication. The additional administration of a tissue adhesive can achieve complete closure of the AVF in the event of an unsatisfactory result following coil embolization. Doctors should be aware of the potential vascular complications of acupuncture, and of the management options.
