An 87-year-old man sustained an intracerebral hemorrhage in the watershed area of the contralateral frontal lobe immediately after carotid artery stenting (CAS) for severe cervical internal carotid artery (ICA) stenosis. The contralateral cervical ICA was occluded. ⋯ This case demonstrates that CAS in patients with contralateral ICA occlusion and insufficient collateral flow can cause dramatically increased collateral flow through the circle of Willis and result in contralateral hyperperfusion. In patients with severely compromised cerebral perfusion, measures should be taken to prevent hyperperfusion-related complications.

This study evaluated the safety and effectiveness of the Zenith Dissection Endovascular System (Cook Medical, Bloomington, Ind) in the urgent treatment of acute type B aortic dissections complicated by organ malperfusion. ⋯ Used as a treatment for organ malperfusion complicating acute type B dissections, the Zenith Dissection Endovascular System achieved safely and effectively satisfactory clinical results in the short term. The long-term effect of this composite treatment on aortic remodelling remains to be determined.

Optimal platelet inhibition is an important therapeutic adjunct in patients with carotid artery stenosis undergoing carotid artery stenting (CAS). Clopidogrel resistance is associated with increased periprocedural thromboembolic complications from neurovascular stent placement procedures. The addition of cilostazol to dual antiplatelet therapy (DAT) has been reported to reduce platelet reactivity and to improve clinical outcomes after percutaneous coronary intervention. This study was undertaken to evaluate the impact of adjunctive cilostazol in patients with CAS. ⋯ Adjunctive cilostazol (triple antiplatelet therapy) in clopidogrel-resistant patients reduces the rate of clopidogrel resistance and suppresses new ischemic lesions without hemorrhagic complications, as compared with standard DAT. Antiplatelet management based on the evaluation of antiplatelet resistance would be required for prevention of perioperative thromboembolic complications in CAS.

The impact of diabetes mellitus on the technical and clinical outcomes of infrainguinal arterial reconstruction (IAR) for critical limb ischemia (CLI) remains controversial. This study analyzed the outcome of IAR in diabetic patients with CLI over a 17-year period. ⋯ Diabetic patients receiving IAR for CLI can have the same survival and amputation-free survival rates as nondiabetic patients. Their comparable technical and clinical outcomes strongly demonstrate that diabetics with CLI can expect the same quantity and quality of life as nondiabetics with CLI, and aggressive attempts at limb salvage in patients with diabetes mellitus, including distal and foot level bypass grafting, should not be discouraged.
