Concomitant multiple revascularizations in supra-aortic arteries: short-term results in 50 patients.

BACKGROUND AND PURPOSE: The outcome for simultaneous revascularization of more than 1 supra-aortic arterial stenosis has not been evaluated because of concerns regarding the increased risk of additional procedures. We evaluated the feasibility and safety of concomitant multiple supra-aortic arterial revascularizations (CMSAR). MATERIALS AND METHODS: We retrospectively evaluated 50 consecutive patients who underwent CMSARs with angioplasty and stent placement. The study included a separate lesion group (LG) (n = 28), ipsilateral LG (n = 17) including adjacent (n = 6) and remote (n = 11) tandem lesions, and triple LG (n = 5). We assessed the procedural success (defined as residual stenosis <30%) and periprocedural event rate (ER) (minor or major stroke, and death). We compared the ERs in the lesion (ipsilateral vs separate) and symptom (unstable vs stable) pattern groups with the Fisher exact test. RESULTS: Procedural success was achieved in all patients (50/50). Periprocedural events within 30 days were noted in 5 (10%). ER within 2 days after the procedure was higher in the ipsilateral LG (4/17) than in the separate LG (0/28) (P = .016). Major events consisting of a major stroke and a death occurred in 2 patients in the unstable group (4%) and was more common in the unstable (2 of 7) than in the stable group (0/38) (P = .029). During the mean 11-month follow-up period, there was 1 symptomatic recurrence. CONCLUSION: CMSARs are feasible with a high procedural success rate resulting in a favorable short-term outcome. However, they must be carefully performed in ipsilateral LG, especially in patients in the unstable group.

Multicystic cavernous haemangioma of the liver: ultrasonography, CT, MR appearances and pathological correlation.

Among the hepatic haemangiomas with atypical features when studied radiologically, the multicystic type is extremely rare. We report a case of multicystic hepatic haemangioma in a 62-year-old woman, which was found incidentally during ultrasound screening. Because the tumour showed atypical features on ultrasonography, CT and MRI, the correct diagnosis was not made until the surgery. In this report, the atypical radiological findings are illustrated and correlated with pathological findings.

Case report. Sclerosing liver haemangioma with pericapillary smooth muscle proliferation: atypical CT and MR findings with pathological correlation.

We report a case of sclerosing liver haemangioma with pericapillary smooth muscle proliferation in a 63-year-old man who presented with abdominal pain. Because the tumour showed atypical features on CT and MRI, a correct diagnosis could not be made until surgery. In this report, the atypical radiological findings are illustrated and correlated with pathological findings.

Can a warning leak in a patient with unruptured aneurysm mask an underlying gastrointestinal pathology? A case report.

Aggravating headache accompanied by nausea and epigastric discomfort suggesting a warning leak in a 39-year-old woman with a giant thrombosed intracranial aneurysm prompted us to undertake coiling of the aneurysm. After uneventful coil embolization of the aneurysm, collapse of the lung related to bronchospam developed, and was found to have a gastrointestinal pathology which had gone undetected before the procedure. Despite its rarity, gastrointestinal pathology mimicking warning leak should have been considered in a patient with a warning leak sign.

Dissecting aneurysm of the basilar arterial trunk presenting with pontine infarction. Coil obliteration of the dissecting aneurysm including the diseased basilar arterial segment.

SUMMARY: Dissecting basilar aneurysms have rarely been reported but are associated with high morbidity and mortality. Therefore, controversy exists as to the proper management of such lesions because their natural course is not well understood. We describe a 50-year-old man with a dissecting aneurysm involving the lower basilar trunk who presented with pontine infarction corresponding to the aneurysmal sac location. We obliterated the dissecting basilar aneurysm by coil embolization of the aneurysmal sac as well as the diseased segment of the basilar trunk after confirmation of collateral filling of the basilar artery through the posterior communicating artery. The patient recovered without any procedural complication. Eight month follow-up revealed complete disappearance of the aneurysm without symptom recurrence together with preservation of collateral flow in the distal basilar artery. Obliteration of the parent artery as well as the aneurysmal sac with coils could be considered in a lower basilar aneurysm of a dissecting nature.
