Patient characteristics with middle cerebral artery stenosis and clinical outcome and complications of stent assisted angioplasty
| Case | Age/sex | Clinical presentation | Medication | SPECT findings | Lesion type | Stent type and size (mm) | Inflation pressure | Follow up SPECT finding | Complications |
|---|---|---|---|---|---|---|---|---|---|
| Medication: pre-operative medication (antiplatelets and/or anticoagulants). | |||||||||
| Lesion type: classified according to the method of Mori et al.8 | |||||||||
| ND, not done; TIAs, transient ischaemic deficits; complication, periprocedural and post-procedural complications; endovascular rescue, arterial rupture was rescued by balloon tamponade and additional overlapping stenting. | |||||||||
| Thrombotic occlusion was treated with intra-arterial administration of abciximab (Reopro; Centocor, Malvern, PA). | |||||||||
| Cases 6 and 10 had unsuccessful stent assisted angioplasty owing to the tortuouity of the internal carotid artery siphon. | |||||||||
