Transition to virtual appointments for interventional neuroradiology due to the COVID-19 pandemic: a survey of satisfaction.

BACKGROUND: The COVID-19 pandemic has changed the way medicine is practiced, including the implementation of virtual care in many specialties. In the field of interventional neuroradiology (INR), virtual clinics are an uncommon practice with minimal literature to support its use. Our objective was to report prospective, single-centre data regarding patient and physician experience with virtual INR clinics for routine follow-up appointments. METHODS: We surveyed all patients that participated in a virtual INR clinic follow-up appointment at our hospital over a 3 month period. Information gathered included length of appointment delays (ie, wait times), length of appointment times, overall satisfaction, and perceived safety metrics. A survey was also sent out to all physicians who participated in virtual clinics with similar questions. RESULTS: 118/122 patients and 6/6 physicians completed the survey. Wait times before previous in-person appointments were perceived to be much longer than virtual appointments, whereas in-person appointment times were longer. 112/118 (94.9%) patients and 4/6 (67%) physicians reported general satisfaction with their virtual clinic experience. There were 8/118 patients who felt their conditions could not be safely assessed virtually, compared with 1/6 (17%) physicians. Lastly, 72.2% of patients reported that they would prefer virtual or telephone visits in the future for non-urgent follow-up, and 5/6 (83%) of physicians reported the same. CONCLUSION: Virtual INR clinics are more efficient and are preferred among patients and physicians for non-urgent follow-up appointments. Our study demonstrates the feasibility of a virtual platform for INR care, which could be sustainable for future practice.

Canadian Registry of LVIS Jr for Treatment of Intracranial Aneurysms (CaRLA).

INTRODUCTION: Stents reduce the rate of angiographic recurrence of intracranial aneurysms. The newest stent for intracranial use is the Low-profile Visible Intraluminal Support device (LVIS Jr). OBJECTIVE: To assess the efficacy of the new stent in a multicenter retrospective registry. MATERIALS AND METHOD: Centers across Canada using LVIS Jr were contacted and asked to participate in a retrospective registry of consecutive patients treated with LVIS Jr for intracranial aneurysms between January 2013 and July 2015. RESULTS: A total of 102 patients, with saccular aneurysms in 100 patients (72 women; age range 21-78 years; mean 56.0 years; median 57.5 years) were treated with a LVIS Jr stent. The mean maximum diameter of the dome and neck of the aneurysm and dome to neck ratios were 8.3 mm±7.7 mm, 4.4 mm±1.9 mm, and 1.86±1.22, respectively. Angiographic complications arose in 23 patients, clinical complications in 9 patients, and only 3% of permanent neurological deficits occurred. Death occurred in 1 patient, unrelated to the stent. The ruptured status of the aneurysms (OR=3.29; p=0.046) and use of LVIS Jr for bailout (OR=2.54; p=0.053) showed a trend towards significant association with higher angiographic complications. At the last available follow-up, 68 class I, 20 class II, and 12 class III results were seen. CONCLUSIONS: The LVIS Jr stent is a safe and effective device for stent-assisted coiling, with 3% permanent neurological complications. Stent-assisted coiling continues to be technically challenging in cases of ruptured aneurysms and bailout situations.

Next day discharge after elective intracranial aneurysm coiling: is it safe?

BACKGROUND: There is a paucity of literature on early discharge after elective aneurysm treatment. We hypothesize that patient discharge on the next day is not associated with an increase in post-discharge adverse events. METHODS: We retrospectively reviewed elective coiling procedures between 2009 and 2013. The primary outcome measure was 30-day adverse events (emergency department visits, readmission or prolonged admission >30 days, and death). We evaluated the association between early and standard discharge for the primary outcome using the Fisher exact test. We also assessed the association of the primary outcome with other patient and technical variables as well as findings on pre-discharge diffusion weighted imaging. RESULTS: We included 97 patients. Median length of hospital stay (LOS) was 2.52 days, and in 26 patients (26.8%) LOS was <2 days. There was no significant difference in post-discharge adverse outcome rates between early and standard discharge groups (19.2% vs 18.3%; p=1.000). The primary outcome was significantly associated with the use of flow diverters (p=0.0287) and change in modified Rankin Scale category at discharge (p=0.0329). No significant association was noted between the outcome and the other variables including the presence of diffusion restriction pre-discharge (p>0.05). CONCLUSIONS: Patient discharge the next day after elective intracranial aneurysm coiling is not associated with an increase in 30-day adverse outcomes. A prospective study investigating early discharge in elective treatment is warranted. TRIAL NUMBER: OHSN-REB #20130786-01H.
