Endovascular Stent Placement

We describe a clinical case of the combined application of endovascular stent placement and GDCoils packing in the management of a ruptured wide necked intracranial aneurysm. A 27-year-old man had a subarachnoid haemorrhage secondary to the rupture of a large wide necked left vertebral aneurysm. This aneurysm was judged to be inoperable. A functional occlusion test failed because of poor collateral flow and combined stenting and coiling was used to occlude the aneurysm with preservation of the parent artery. A femoral approach was used. An 18 mm long ACS® Duet stent was placed across the base of aneurysm and expanded to 4mm to act as a buttress. A microcatheter was then advanced through the stent mesh and GDC's were deposited for occlusion. This technique provides new possibilities for wide-necked intracranial aneurysms. Further studies are required on the mechanical and thrombogenic properties of stents and on the long-term follow-up, but this technology may play a role in some cases of aneurysm treatment.

Vertebral Artery Compression

Introduction: The authors propose a new terminology, Rotational Ischemic Vertebral Artery Compression (RIVAC) syndrome, to describe patients who present with TIA or stroke from compression of the cervical vertebral artery (VA) below C2 by facet hypertrophy or uncinate process osteophyte associated with rotation of the head. The authors review clinical presentation, radiological findings, and management of 7 consecutive cases. Methods: Prospective analysis of 7 consecutive cases of RIVAC syndrome was performed between 2004 and 2012. We reviewed peri-operative imaging, method of treatment, and clinical and angiographic outcome. Results: A total of 6 patients (mean 66+/- 4 years) presented with stroke (N=2) or TIA including reproducible dizziness, vertigo, or syncope (N=4) associated with rotation of the head. Pre-operative dynamic cerebral angiogram showed near complete occlusion of cervical VA (N=2) or severe stenosis (60 to 80%) (N=5) during rotation of the head. The location of cervical VA compression was as follows: right C3-4 (N=1), left C4-5 (N=3), left C5-6 (N=2) and left C6-7 (N=1). Treatment included endovascular stent placement of VA without open surgery (N=1), endovascular stent placement of VA followed by partial left C5-6 factectomy 2 years later (N=1), posterior surgical decompression of VA along with bilateral facet screw fixation (N=4), and anterior cervical discectomy and fusion (N=1). Follow up dynamic cerebral angiograms and CTA angiogram of neck (6 months to 3 years) showed resolution of VA compression on rotation of head in all patients except for one who had lost in follow up. Clinical evaluation (range of 1 to 48 months) showed no recurrent stroke or TIA in all patients (mRS score of 0, N=6 and mRS of 3, N=1). Conclusion: RIVAC syndrome should be recognized as an important cause of posterior circulation TIA or stroke associated with rotation of head. Pre-operative dynamic cerebral angiogram and CT angiogram of neck are essential in localization and characterization of the level and cause of VA compression. Open surgical decompression and fixation appears to be safe and effective treatment of patients with RIVAC syndrome.

The objective of this study was to determine the outcome of cats with ureteric obstruction managed with double pigtail ureteric stents and to document the incidence of lower urinary tract signs at long-term follow-up. Data were obtained retrospectively from the medical records (2009–2012) of 26 cats that underwent ureteric stent placement. Owners were contacted for follow-up, and a quality of life questionnaire completed. Survival to discharge after stent placement was 85% (22/26). Prevalence of postoperative uroabdomen necessitating further surgery was 15% (4/26). Stents were replaced 4–28 months after the initial surgery in four cats because of migration, fracture, encrustation causing luminal obstruction or sterile cystitis, respectively. Nine cats were alive at follow-up, which was 3–28 months after the original surgery. Nine cats had azotaemic chronic kidney disease and nine had signs related to sterile cystitis; three of these cats were euthanased as a result of the severity of the signs. Preoperative serum creatinine of the survivors (9.4 mg/dl, n = 9) was not significantly different from that of the non-survivors (6.5 mg/dl, n = 13; P = 0.295). Quality of life was assigned a mean score of 8/10. Median survival of cats following discharge was 419 days (range 44–994 days). Signs consistent with sterile cystitis affected 35% of cats. It was concluded that ureteric stent placement in cats was associated with a 15% mortality rate before hospital discharge. Long-term management of ureteric stents is associated with a high rate of lower urinary tract signs.
