The natural history of acute carotid artery dissection is poorly characterized. The purpose of this study is to report on single institutional long-term outcomes. ⋯ Most cervical carotid dissections can safely be conservatively managed, with the majority achieving anatomic and symptomatic resolution, with low rates of recurrence over long-term follow-up.

Effect of carotid sinus nerve blockade on hemodynamic stability during carotid endarterectomy under local anesthesia.
To find out whether routine carotid sinus nerve blockade with lidocaine during carotid endarterectomy under local anesthesia results in perioperative changes in blood pressure and heart rate. ⋯ Routine infiltration of carotid sinus area with 1% lidocaine during carotid endarterectomy performed under local anesthesia has no significant impact on mean arterial blood pressure and heart rate during the operative procedure and the following 12 postoperative hours.

Structural changes within the aorta after thoracic endovascular aortic repair (TEVAR) for acute complicated type B thoracic aortic dissections (ABAD) remain unknown. This study reviewed and analyzed morphologic changes, volumetric data, and clinical outcomes of patients with ABAD. ⋯ TEVAR offers a promising solution to patients with ABAD. Aortic morphologic changes occur shortly after TEVAR and remain predictable up to 5 years with continuous expansion of the true lumen and regression of the false lumen. A lack of increase in the true lumen volume is associated with endoleaks or distal reperfusion.

Spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) is extremely rare. Various treatment options are currently available, including conservative management, anticoagulation, endovascular stenting, and surgical repair. Herein, we present our experience in the treatment of symptomatic SIDSMA. ⋯ Conservative management without anticoagulation can be applied successfully to the patients with symptomatic SIDSMA. Primary endovascular stenting is indicated if patients have suspected bowel ischemia, compression of the true lumen of the SMA >80%, or SMA aneurysm of >2.0 cm in diameter on initial CT scan. Endovascular stenting can also be provided to the patients in whom initial conservative treatment failed, as a rescue therapy.

The objective of this study is to examine contemporary management of primary mycotic aortic aneurysms in a single center. We have previously reported the management of mycotic aortic aneurysms in 15 patients between 1991 and 2001, and we hypothesized that management would change in the light of the evolution of endovascular aortic repair. ⋯ The results of the latest series show that open surgery is still required in many cases. The introduction of endovascular techniques in the exclusion of mycotic aneurysms can be accomplished with acceptable results, and endovascular treatment has increased the therapeutic options for a difficult condition.
