A significantly higher incidence of symptoms of pelvic ischemia occurred with more distal placement of coils for IIA embolization. Failure to control for extent of coil placement may account for the apparently conflicting results in published studies. IIA coil embolization should be performed as proximal as possible to prevent interference with pelvic collateral circulation.

Significant CIA ectasia or small aneurysm is often associated with AAA. In such cases, the bell-bottom procedure that preserves IIA circulation is a new alternative to the common practice of placement of endograft extensions across the iliac artery bifurcation in patients with at least one CIA diameter of less than 26 mm. Additional benefits include reduced total procedure time. Early technical success appears to justify continued use. However, long-term evaluation is necessary to determine durability because the risk of rupture as the result of potential expansion of the excluded iliac artery or late failure is unknown.

Our study indicates that early recanalization with MT followed by emergent CEA is safe and feasible, which suggests that both CAS and CEA should be considered in the emergent treatment of patients with tandem occlusion.

In the past decade, expected in-hospital length of stay (LOS) after carotid endarterectomy (CEA) has decreased from 4 days to 1. Long LOS is associated with known complications and factors affecting severity of the patient's condition. Factors affecting an intermediate stay of 2 to 4 days need further clarification. The vascular registry at Jobst Vascular Center includes data on manifestation of disease; cardiovascular history; operation and discharge dates; surgeon; surgical details such as patching, shunting, and completion arteriography; and complications. Univariate chi-square and ANOVA and multivariate logistic regression were applied to analyze 635 CEAs performed in 1998, 1999, and 2000. Statistical significance was at a p value less than 0.05 (two-sided). Overall morbidity rate was 8.2% with three (0.5%) inhospital neurologic complications and one death for a 0.16% mortality rate. Fifty-eight percent of the patients were discharged in 1 day. Patients staying 1 day were 3 years younger. Female gender and prior cerebrovascular accident were factors extending LOS to 2 and 3 days. History of angina, heart failure, valve disease, and vein patch or no patch contributed to LOS of 3 or 4 days. Completion arteriography had an association with LOS of 2 days. The relative percentage of patients with complications increased with LOS. No significant relationship was found for symptoms, smoking, myocardial infarction, atrial fibrillation, cardiac revascularization, or surgeon. Insulin-treated diabetes mellitus, cardiac risk factors, cerebrovascular accident, and vein patch or no patch correlated with prolonged hospitalization. Factors were identified that may alter a clinical pathway designed for discharge 1 day after CEA. Focused management of patients with cardiac and cerebrovascular accident history or requiring vein patch and a better understanding of CEA in women may further increase the percentage of patients discharged 1 day after CEA.
