Comparative Study
Contralateral stenosis as a risk factor for carotid endarterectomy measured by near infrared spectroscopy.
It is still controversial whether the existence of a contralateral stenosis is a risk factor during carotid endarterectomy (CEA). We used a near infrared spectroscopy (NIRS) monitoring system during CEA to evaluate the hemodynamic effect of contralateral stenosis during cross clamping of the carotid arteries. ⋯ A contralateral stenosis is a risk factor for CEA from the hemodynamical point of view, and extreme care should be taken when performing CEA in patients with bilateral stenoses.

The incidence of venous thromboembolism (VTE) is increasing in children as a result of therapeutic advances and improved clinical outcome in primary illnesses that previously caused mortality. VTE is mostly diagnosed in hospitalized children, especially sick newborns with central venous catheters and older children with a combination of risk factors. Infants older than 3 months and teenagers are the largest groups developing VTE. ⋯ This supports the need for international multicenter randomized clinical trials to determine optimal prophylactic and therapeutic treatment for children with VTE. Risk factor assessment for VTE in children has to be improved in order to optimize the prophylactic and therapeutic strategies. The specific evolutionary characteristics of the hemostasis in children has to be taken into consideration when a prophylactic or therapeutic strategy is applied.

The aim of the present study was to quantify intima-media thickness (IMT) of the common carotid artery (CCA) in clinically asymptomatic members of familial combined hyperlipidemia (FCHL) families and to evaluate its association with lipids, apoproteins, blood pressure, surrogate markers of insulin resistance, fibrinogen and hs-CRP. ⋯ The increase of IMT CCA in hyperlipidemic still clinically asymptomatic FCHL subjects corresponds to acceleration of the clinically ''silent'' atherosclerosis by about 8-14 years and is in agreement with their increased risk of atherosclerosis.

The purpose of this study was to review our experience with popliteal artery aneurysms (PAAS) and to identify the major factors associated with thromboembolism of PAAS and failure of grafts after surgical repair. ⋯ Our experience indicates that SFA occlusion and poor runoff vessels were independent factors associated with PAA thrombosis. The diameter of asymptomatic PAAs was not significantly different than that of asymptomatic ones. Use of tobacco and poor runoff vessels were independent factors associated with primary bypass patency. In PAAs complicated with acute ischemia, thrombolysis allowed us to regain a good runoff and to perform subsequent bypass procedure, with no amputation. The use of autogenous graft material, when possible, is recommended.

We report a case of tuberculous pseudoaneurysm in the neck of the celiac artery involving the aorta. Recurrence of the aneurysm occurred after attempted direct repair. Therefore redo-surgery was performed, which involved resection of aneurysm and removal of the infected tissue with bilateral axillofemoral bypass.
