Practical Incidence of Complications and Degree of Patient Satisfaction After Endovascular Coil Embolization for Unruptured Intracranial Saccular Aneurysm Based on Patients' Surveys.

OBJECTIVE: Endovascular treatment for unruptured intracranial aneurysms (UIAs) has been regarded as second to none management nowadays as the result of its proven efficacy and need for less-invasive treatment. Most researchers have focused on the anatomical outcome after endovascular treatment, so in this study we estimated the real incidence of untoward effect and degree of patients' satisfaction based on s survey. METHODS: This retrospective study was approved by the institutional review board, and 112 patients treated for saccular UIAs were evaluated among a total of 135 patients. After informed consent was obtained, these patients were sent a questionnaire regarding treatment effectiveness, complications, and patient satisfaction. These data were collected and compared with angiographic and clinical outcome. RESULTS: The response rate was 87.5% (98/112). Intracranial complications occurred in 10 aneurysms (10.2%): 7 ischemic and 3 hemorrhagic strokes. Other complications occurred in 30 patients (30.6%): 17 alopecia, 15 bleeding tendency, and 3 puncture-site complications. Overall, 89 (90.8%) patients reported being satisfied with their treatment. Patient satisfaction was closely correlated with clinically successful outcome of treatment. CONCLUSIONS: Ninety percent of patients were satisfied with the results after endovascular treatment of UIAs. Endovascular coil embolization was effective and safe procedure, with high clinical success rate and degree of satisfaction.

Efficacy and safety of prostate artery embolization for benign prostatic hyperplasia: an observational study and propensity-matched comparison with transurethral resection of the prostate (the UK-ROPE study).

OBJECTIVES: To assess the efficacy and safety of prostate artery embolization (PAE) for lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) and to conduct an indirect comparison of PAE with transurethral resection of the prostate (TURP). PATIENTS AND METHODS: As a joint initiative between the British Society of Interventional Radiologists, the British Association of Urological Surgeons and the National Institute for Health and Care Excellence, we conducted the UK Register of Prostate Embolization (UK-ROPE) study, which recruited 305 patients across 17 UK urological/interventional radiology centres, 216 of whom underwent PAE and 89 of whom underwent TURP. The primary outcomes were International Prostate Symptom Score (IPSS) improvement in the PAE group at 12 months post-procedure, and complication data post-PAE. We also aimed to compare IPSS score improvements between the PAE and TURP groups, using non-inferiority analysis on propensity-score-matched patient pairs. The clinical results and urological measurements were performed at clinical sites. IPSS and other questionnaire-based results were mailed by patients directly to the trial unit managing the study. All data were uploaded centrally to the UK-ROPE study database. RESULTS: The results showed that PAE was clinically effective, producing a median 10-point IPSS improvement from baseline at 12 months post-procedure. PAE did not appear to be as effective as TURP, which produced a median 15-point IPSS score improvement at 12 months post-procedure. These findings are further supported by the propensity score analysis, in which we formed 65 closely matched pairs of patients who underwent PAE and patients who underwent TURP. In terms of IPSS and quality-of-life (QoL) improvement, there was no evidence of PAE being non-inferior to TURP. Patients in the PAE group had a statistically significant improvement in maximum urinary flow rate and prostate volume reduction at 12 months post-procedure. PAE had a reoperation rate of 5% before 12 months and 15% after 12 months (20% total rate), and a low complication rate. Of 216 patients, one had sepsis, one required a blood transfusion, four had local arterial dissection and four had a groin haematoma. Two patients had non-target embolization that presented as self-limiting penile ulcers. Additional patient-reported outcomes, pain levels and return to normal activities were very encouraging for PAE. Seventy-one percent of PAE cases were performed as outpatient or day cases. In contrast, 80% of TURP cases required at least 1 night of hospital stay, and the majority required 2 nights. CONCLUSION: Our results indicate that PAE provides a clinically and statistically significant improvement in symptoms and QoL, although some of these improvements were greater in the TURP arm. The safety profile and quicker return to normal activities may be seen as highly beneficial by patients considering PAE as an alternative treatment to TURP, with the concomitant advantages of reduced length of hospital stay and need for admission after PAE. PAE is an advanced embolization technique demanding a high level of expertise, and should be performed by experienced interventional radiologists who have been trained and proctored appropriately. The use of cone-beam computed tomography is encouraged to improve operator confidence and minimize non-target embolizations. The place of PAE in the care pathway is between that of drugs and surgery, allowing the clinician to tailor treatment to individual patients' symptoms, requirements and anatomical variation.

Role of Locoregional Therapy and Predictors for Dropout in Patients with Hepatocellular Carcinoma Listed for Liver Transplantation.

PURPOSE: To identify factors associated with removal from the liver transplantation waitlist because of death, deterioration of condition, or exceeding Milan criteria in patients with hepatocellular carcinoma (HCC), with emphasis on the role of locoregional therapy (LRT), defined as percutaneous thermal ablation and drug-eluting embolic chemoembolization, as bridge therapy. MATERIALS AND METHODS: All patients listed for liver transplant at a single institution with exception points for HCC during 2004-2012 were evaluated. The most common cause of cirrhosis was hepatitis C (68%; 121/177). Seventy-one percent (125/177) of patients underwent liver transplantation, and 83% (147/177) underwent at least 1 LRT procedure. Of the 52 patients who did not undergo liver transplantation, 31 (60%) of livers were removed because of progression of HCC. RESULTS: The likelihood of transplant was higher for patients who received LRT (odds ratio [OR], 2.9; confidence interval [CI], 2.2-7.2) and lower for patients with multifocal tumors (OR, 0.25; CI, 0.12-0.52) and with larger tumors (OR, 0.94; CI, 0.90-0.98). Time on the waitlist (OR, 0.99; CI, 0.99-1.0) was not found to correlate with removal. LRT increased the likelihood of liver transplantation, specifically for patients with prolonged wait times. Patients who demonstrated complete response (CR) to LRT on the first follow-up imaging study were more likely to undergo liver transplantation. CONCLUSIONS: LRT increased the likelihood of a patient with HCC achieving liver transplant, particularly in patients facing prolonged waiting times. CR after LRT significantly increased the likelihood of liver transplantation.

A blinded, randomized study of L-arginine in small clot embolized rabbits.

OBJECTIVE: Tissue plasminogen activator (tPA) is administered to acute ischemic stroke victims in a vehicle formulation containing high concentrations of L-arginine (3.5g/100mg vial), a well-known nitric oxide synthase (NOS) substrate and precursor to nitric oxide (NO), as well as an enhancer of cerebral blood flow. METHODS: We studied the effects of tPA vehicle compared to tPA (3.3mg/kg) formulated in the same vehicle containing L-arginine, normal saline or normal saline containing L-arginine, on behavioral function following small clot embolic strokes in rabbits using clinical rating scores and quantal analysis curves as the primary end point. Treatments were administered intravenously (1ml/kg; 20% bolus/80% infused over 30min) starting 1h following the injection of small-sized blood clots into the brain vasculature and terminal behavior was measured 2days following embolization. Behavioral rating scores were used to calculate the effective stroke dose (P50 in mg) that produces neurological deficits in 50% of the rabbits. RESULTS: In this study, tPA significantly (p=0.001) improved behavior compared to all other treatments including tPA vehicle, saline and saline-L-arginine, increasing the P50 by 141% over tPA vehicle. Saline-L-arginine was not significantly different from either saline or tPA vehicle (p>0.05). CONCLUSION: This study demonstrates that the L-arginine component of the tPA vehicle does not contribute to the reproducible clinical improvement observed following tPA administration in rabbits. Moreover, the administration of L-arginine was not an effective method to promote behavioral recovery following embolic strokes in the stringent rabbit small clot stroke model, nor did L-arginine exacerbate behavioral deficits or intracerebral hemorrhage in embolized rabbits.

Quality of life and outcome after treatment of ruptured cerebral aneurysms: results of a single center in Switzerland.

OBJECT: To evaluate the subjective outcome and quality of life (QoL) of patients who suffered from aneurysmal subarachnoid hemorrhage and underwent endovascular coiling or microsurgical clipping in a single center. METHODS: For this retrospective single-center study, we included patients who underwent aneurysm occlusion at the Cantonal Hospital of Aarau between January 2000 and December 2006. The QoL, the functional status, and the level of independence were assessed by means of the Short Form (SF)-12 Health Survey, the modified Rankin Scale (mRS), and the Barthel Index. The questionnaires were sent to and completed by the patients. A total of 104 patients with a mean age of 53.14 years (range, 18-80 years) were included in the study. In 63 (60.6 %) of the cases, the aneurysm was clipped; in 41 (39.4 %) of the cases, endovascular coiling was performed. RESULTS: The SF-12 scores for the PCS (Physical Component Summary) and MCS (Mental Component Summary) were similar for both clipped (PCS 45.35; MCS 46.55) and coiled (PCS 46.31; MCS 47.87) patients. The mean values were, on average, 4.17 points lower for the PCS and 2.79 points lower for the MCS when compared with the mean of the US population, with a mean of 50 (standard deviation (SD) 10). The mean Barthel Index for the entire group was 92.26 (SD 16.8) and was almost identical for both the clipped (92.54; SD 16.21) and coiled (91.83; SD 17.9) patients (p = 0.56). The mean mRS did not differ between the coiled and clipped patients (coiled 1.63; clipped 1.56; p = 0.97) CONCLUSIONS: There were no significant differences in the functional and mental health scores between the two groups of clipped and coiled patients who were treated at our center, but both groups were lower than population-based scores. Although the neurologic condition and the imaging results on admission were worse in the coiled group, the long-term results did not differ significantly.

The impact of uterine leiomyomas: a national survey of affected women.

OBJECTIVE: We sought to characterize the impact of uterine leiomyomas (fibroids) in a racially diverse sample of women in the United States. STUDY DESIGN: A total of 968 women (573 white, 268 African American, 127 other races) aged 29-59 years with self-reported symptomatic uterine leiomyomas participated in a national survey. We assessed diagnosis, information seeking, attitudes about fertility, impact on work, and treatment preferences. Frequencies and percentages were summarized. The χ(2) test was used to compare age groups. RESULTS: Women waited an average of 3.6 years before seeking treatment for leiomyomas, and 41% saw ≥2 health care providers for diagnosis. Almost a third of employed respondents (28%) reported missing work due to leiomyoma symptoms, and 24% believed that their symptoms prevented them from reaching their career potential. Women expressed desire for treatments that do not involve invasive surgery (79%), preserve the uterus (51%), and preserve fertility (43% of women aged <40 years). CONCLUSION: Uterine leiomyomas cause significant morbidity. When considering treatment, women are most concerned about surgical options, especially women aged <40 years who want to preserve fertility.

Quality of life after treatment of unruptured intracranial aneurysms by neurosurgical clipping or by embolisation with coils. A prospective, observational study.

BACKGROUND: Relatively high rates of complications occur after operation for unruptured intracranial aneurysms. Published data on endovascular treatment suggest lower rates of complications. We measured the impact of treatment of unruptured aneurysms by clipping or coiling on functional health, quality of life, and the level of anxiety and depression. METHODS: In three centres, we prospectively collected data on patients with an unruptured aneurysm who were treated by clipping or coiling. Treatment assignment was left to the discretion of the treating physicians. Before, 3 and 12 months after treatment, we used standardised questionnaires to assess functional health (Rankin Scale score), quality of life (SF-36, EuroQol), and the level of anxiety and depression (Hospital Anxiety and Depression Scale). RESULTS: Nineteen patients were treated by coiling and 32 by clipping. In the surgical group, 4 patients (12%) had a permanent complication; 36 of all 37 aneurysms (97%) were successfully clipped. Three months after operation, quality of life was worse than before operation; 12 months after operation, it had improved but had not completely returned to baseline levels. Scores for depression were higher than in the general population. In the endovascular group, no complications with permanent deficits occurred; 16 of 19 aneurysms (84%) were occluded by more than 90%. One patient died from rupture of the previously coiled aneurysm. In the others, quality of life after 3 months and after 1 year was similar to that before treatment. CONCLUSIONS: In the short term, operation of patients with an unruptured aneurysm has a considerable impact on functional health and quality of life. After 1 year, recovery occurs but it is incomplete. Coil embolisation does not affect functional health and quality of life.

Changing trends in gynecologists' opinions of uterine artery embolization for fibroids: the patient's perspective.

This study's purpose was to survey patients' perceptions of gynecologists' opinions of uterine artery embolization (UAE) for fibroids. Twenty-one women who underwent UAE between July 2000 and April 2002 and 21 women who underwent UAE between September 1998 and July 2000 completed questionnaires. Each woman was asked what her gynecologist's initial opinion was toward UAE, what treatment options were offered, who initiated discussion of UAE, and whether she returned to the same gynecologist after UAE. As of 2002, more gynecologists had a favorable opinion of UAE and were offering UAE versus in the year 2000. The majority of patients whose gynecologists initially opposed UAE did not return to the same gynecologists, reflecting a similar trend noted 2 years earlier.

Fibroid embolisation: a technique not without significant complications.

Uterine artery embolisation is a new minimally invasive technique used for the treatment of fibroids. Twenty-one women underwent bilateral uterine artery embolisation at our unit, and we assessed the efficacy, morbidity and patient satisfaction with the procedure. Mixed outcomes were found. Reduction in fibroid volume measured by magnetic resonance imaging was impressive, and the majority of women felt their symptoms had improved. One woman achieved a full term pregnancy following the procedure. However, the procedure involved a significant inpatient stay, analgesia requirement, and a slower recovery time than anticipated. One woman died following overwhelming sepsis occurring 10 days after the procedure. Further studies are required to assess the role this technique may play in the management of uterine fibroids.

Arterial embolisation of uterine fibroids.

Interventional radiology has advanced rapidly in recent years as new technology has become available, and now offers viable alternatives to some surgical techniques. An example of this evolution is arterial embolisation of uterine fibroids. This article will explore some of the nursing issues associated with this procedure.

Efficacy of a stress management program for patients with hepatocellular carcinoma receiving transcatheter arterial embolization.

Transcatheter arterial embolization (TAE), a common treatment for patients with unresectable hepatocellular carcinoma (HCC), can provoke severe physical discomfort and psychologic stress. The purpose of this study was to investigate the effect of a combination of health education, muscle relaxation, and back massage on reducing physical and psychologic stress in HCC patients receiving TAE. A quasi-experimental design was used. Forty patients with HCC (30 men and 10 women) with a mean age of 57 +/- 12 years were recruited and randomly assigned to the control or experimental group. The effectiveness of the stress management program was evaluated using a knowledge questionnaire, a worry inventory, a state-trait anxiety inventory, and a physical distress scale. After completing the stress management program, the experimental group had a greater mean increase in knowledge score than the control group (5.1 vs 0.8, p < 0.0001) and a greater mean decrease in worry score (-8.2 vs 1.1, p < 0.0001). The mean decrease in the anxiety score in the experimental group was also significantly greater than in the control group before TAE (-5.8 vs 3.2, p < 0.001) and 2, 4, 6, and 7 days after TAE (-8.2 vs 7.1, p < 0.001; -8.7 vs 3.2, p < 0.001; -9.8 vs -2.1, p < 0.05; -11 vs -0.9, p < 0.05). The patients in the experimental group had a smaller mean increase in physical distress score than the control group at 2, 4, 6, and 7 days after TAE (34.7 vs 50.2, 20.9 vs 29.6, 10.6 vs 18.2, 3.9 vs 11.2, all p < 0.05). This stress management program effectively reduces the stress of HCC patients undergoing TAE.

Spinal arteriovenous malformations. Health-related quality of life after embolization.

The overall function, pain and mood disturbances of 19 patients with spinal arteriovenous malformations (AVM), treated by embolization between 1983 and 1988, were studied. The after-care had taken place in different hospitals and clinics. The patients demonstrated markedly poorer physical function (Sickness Impact Profile) and poorer psychological well-being (Mood Adjective Check List) than control population samples and a comparison group of traumatic incomplete paraplegics. The degree of decrease of mood levels implied possible depressive disorder (Hospital Anxiety and Depression scale) in 16% of the patients and differed from that of the paraplegic comparison group. Furthermore, the AVM patients reported more disturbance of their family and social life than the paraplegics and they were more seldom gainfully employed. Patients recorded a wide range of pain scores, significantly worse than the paraplegics, and their pain was closely linked to overall quality of life (QL) perception. The QL scores were consistently related to all measures of functional and emotional status, but no connection with neurological lesion levels or medical complications was found. Specialised programmes after embolization, such as those offered in spinal injury units, would appear appropriate for AVM patients to improve their physical functioning and to provide a more rewarding social life.
