Purpose: To evaluate the feasibility and safety of sac embolization with N-butyl cyanoacrylate (NBCA) in emergency endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysm (AAA) and iliac artery aneurysm (IAA) in comparison to EVAR without sac embolization. Materials and Methods: Between February 2012 and December 2019, among 44 consecutive patients with ruptured AAA or IAA, 29 underwent EVAR. Of these, 22 patients (median age 77.5 years; 18 men) had concomitant sac embolization using NBCA; the remaining 7 patients (median age 88 years; 6 men) underwent EVAR without sac embolization and form the control group. The technical success, clinical success (hemodynamic stabilization), procedure-related complications, and mortality were compared between the groups. Results: All EVAR procedures and embolizations were successful. The clinical success rates in the NBCA and control groups were 95% (21/22) and 71% (5/7), respectively (p=0.14). There was no complication related to the procedure. Type II endoleak occurred in 4 of 21 patients (19%) in the NBCA group vs none of the control patients. One patient (5%) died in the NBCA group vs 3 (43%) in the controls (p=0.034). Conclusion: Sac embolization using NBCA in emergency EVAR appears to be feasible and safe for ruptured AAA and IAA.

We prospectively evaluated thin-slice coronal turbo spin-echo (TSE) diffusion-weighted imaging (DWI) covering a larger area with the recently-developed techniques on a 3T MRI scanner, compared with echoplanar imaging (EPI)-DWI in patients undergoing routine hand MRI. Visual score assessment and apparent diffusion coefficient (ADC) measurement were performed for patients with suspected hand tumors. TSE-DWI was superior to EPI-DWI, with less image distortion. The visual score and ADC comparison assessments proved that the image noise of TSE-DWI was acceptable.breast and lung cancers, and spinal cord infarction. 1,5-10 To the best of our knowledge, however, there have been no TSE-DWI studies evaluating musculoskeletal lesions of the hand or foot. In addition, only one previous case report evaluated middle ear cholesteatoma using 2-mm-thick single-shot TSE-DWI, but ADC measurement was not performed and the acquisition time was not presented. 6 TSE-DWI using the recently-developed parallel imaging and single-shot technique on 3T MRI might yield a superior image quality and is already used clinically. However, the image quality of thin-slice TSE-DWI for the assessment of small musculoskeletal lesions has not yet been clarified. Thus, the purpose of this study was to prospectively examine whether the 2-mm-thick coronal TSE-DWI covering a larger area and small lesions could substitute for conventional EPI-DWI in patients undergoing routine hand MRI on a 3T scanner. Materials and Methods Study designThis prospective study was performed in accordance with the ethical standards of our Institutional Review Board. Written informed consent was obtained from the patients and their privacy was completely protected. Eligibility criteria for entry were: (1) adult patients suspected of having or being followed for a musculoskeletal tumor of the hand or finger, (2) patient agreement to cooperate, and (3) examination on a Philips 3T MRI scanner (Ingenia; Philips Medical Systems, Eindhoven, The Netherlands). The exclusion criteria were:(1) contraindications to MR (incompatible metal implants or pacemakers), and (2) motion artifacts and artifacts from unsuppressed fat on the images.
