Vascular function and carotid intimal-medial thickness in children with insulin-dependent diabetes mellitus.

Objectives: The objective of this study was to evaluate endothelium-dependent vasodilation and carotid intimal-medial thickness (IMT) in children with insulin-dependent diabetes mellitus.

Background: Diabetes mellitus is an established risk factor for atherosclerosis. Vascular complications of diabetes are not clinically evident in diabetic children.

Duplex examination of the inferior vena cava.

Duplex examination of the inferior vena cava (IVC) was performed in 270 patients from 1/1/96 to 1/1/00 to define suitability of the IVC for caval interruption using noninvasive means. The IVC was interrogated using a 3-mHz curved linear array probe and an ATL Ultramark 9 ultrasound machine (Bothell, WA). Duplex measured IVC dimensions and defined presence of thrombus or anomalies.

Do patients with acute deep vein thrombosis have fever?

The purpose of this study was to determine whether those with lower extremity acute venous thrombosis have fever. During a recent 14.5-month period, 1847 patients undergoing lower extremity venous duplex scanning also had their oral temperature measured using a digital thermometer at the time of duplex examination.

Acute calf vein thrombosis: outcomes and implications.

The purpose of this study was to define the incidence of and outcomes associated with isolated acute calf vein thrombosis (CVT). From 11/95 through 6/97, 3096 patients underwent lower extremity venous duplex testing in a hospital-based vascular laboratory in which bilateral tibial and peroneal vein imaging were standard components of the venous duplex examination. CVT was present in 118 patients (3.

Effects of autonomic neuropathy on coronary blood flow in patients with diabetes mellitus.

Background: C ardiac sympathetic signals play an important role in the regulation of myocardial perfusion. We hypothesized that sympathetically mediated myocardial blood flow would be impaired in diabetics with autonomic neuropathy.

Methods And Results: We studied 28 diabetics (43+/-7 years old) and 11 age-matched healthy volunteers.

Nonoperative therapy for postcatheterization femoral artery pseudoaneurysms.

Since November 1992, 160 patients were referred to the Vascular Surgery Laboratory for duplex scanning to assess whether a femoral artery pseudoaneurysm was present. Of these patients, 33 per cent (n = 53) had femoral artery pseudoaneurysms with maximal diameters ranging from 1.5 to 8.

Vena cava duplex imaging before caval interruption.

Purpose: Venacavograms are routinely obtained before vena cava filter placement to evaluate cava size, patency, and the presence of thrombus or venous anomalies. The objective of this study was to determine the ability of duplex ultrasonography to adequately evaluate the inferior vena cava (IVC) for size, patency, and the presence of thrombus before Greenfield filter (GF) insertion.

Methods: Duplex ultrasonographic scans were performed in 40 patients who had documented lower-extremity deep venous thrombosis diagnosed by duplex scan before GF placement.

Assessment of noninvasive lower extremity arterial testing versus pulse exam.

Palpation of pedal pulses was compared to noninvasive testing in 100 patients referred to a vascular laboratory. Subjects were 65 +/- 13 (mean +/- s.d.
