“…In fact, we noted gross debris in five of the six patients in the blood aspirated after postdilatation, indicating that the risk of intraoperative embolic events is high without the use of EPD. Hayashi et al 10) reported that plaque is related to stenosis near the petrous portion of the ICA. Ito et al 11) performed angioplasty of the coronary artery using a balloon-expandable stent without the EPD in 31 patients with stenosis of this site and reported embolic complications in 4 (12.9%).…”

Objective: Six cases in which carotid artery stenting (CAS) was performed using a distal embolic protection device (EPD) for distal internal carotid artery (ICA) stenosis near the carotid canal are reported.Case Presentations: Of the 504 consecutive cases of ICA stenosis endovascularly treated at our hospital between April 1, 2008 and December 31, 2016, six cases with lesions in the distal potion of the cervical ICA near the carotid canal underwent CAS using Carotid Guardwire PS. The six patients were all males aged 68-80 years (median: 78.5 years), and three patients were symptomatic. The mean percent stenosis was 91% (80%-96%) preoperatively and 10.3% (0%-27%) postoperatively. In five patients, gross debris was detected in the blood aspirated during the procedure.In the patient with 27% residual stenosis, calcified plaque was confirmed at the entry of the carotid canal on postoperative CTA. No stroke, myocardial infarction, or death was noted within 30 days after the perioperative period, but a new ischemic lesion was detected in one patient on diffusion-weighted MRI. The mean follow-up period in the six patients was 28 months (7-66 months), and ipsilateral stroke or restenosis was not observed.Conclusion: CAS using EPD is considered an effective option for the treatment of distal ICA stenosis near the carotid canal.

Objective: To evaluate the success rate of eustachian tube (ET) occlusion in subtotal petrosectomy relative to the occlusive material used and to the varying protympanum anatomy, by means of standardized alignment of the cochlea-carotid artery relation on computed tomography images. Patients and methods: All cases of subtotal petrosectomy carried out by the same surgeon at a tertiary care referral center were retrospectively evaluated. Only cases with available computed tomography prior to second stage cochlear or middle ear implantation were included. The occlusive material was either muscle tissue or oxidized regenerated cellulose in combination with bone wax. On 3D multiplanar image reconstruction, the varying topographic interrelation of the cochlea and the petrous carotid artery was measured and categorized into two groups: detachment or overlapping. Results: In 9 (31%) of the 29 included cases there was insufficient occlusion of the ET. In none of these cases was an infection of the fat filling in the obliterated cavity observed during the implantation procedure on second stage (average 10 months interval). The failure rate of both occlusion materials was almost the same (using muscle tissue, in 4 (33.3%) of 12 or oxidized regenerated cellulose, in 5 (29.4%) of 17 cases). It was also similar for both materials in each of the anatomic variation groups. Conclusions: An incomplete occlusion of the ET alone does not appear to lead to an infection of the obliterated cavity. Autologous muscle tissue and oxidized regenerated cellulose had similar rates of ET occlusion failure. The topographical variance of the protympanum appears to have no direct influence on the success of the ET occlusion.
