Percutaneous thrombectomy: a review.

Percutaneous thrombectomy (PT) is an established technique for the removal of acute thrombus in occluded arteries, veins and vascular grafts. Percutaneous thrombectomy can be used as an adjunctive treatment to other methods of thrombus removal such as thrombolysis or as sole therapy. The two main methods are percutaneous aspiration thrombectomy in which thrombus is removed by suction with the aid of wide-bore catheters, and mechanical thrombectomy using a variety of automated devices to fragment or remove thrombus. Aspiration thrombectomy is often used as an adjunct to thrombolysis in acute arterial occlusion, or as salvage therapy to remove distal emboli following iliac or femoropopliteal angioplasty. Mechanical thrombectomy is useful for the treatment of thrombosed dialysis grafts and is being increasingly used for the treatment of massive pulmonary emboli and ileofemoral or ileocaval deep venous thromboses.

Outcomes of endovascular abdominal aortic aneurysm repair in patients with hostile neck anatomy.

PURPOSE: The principal anatomic contraindication to endovascular aneurysm repair (EVR) is an unfavorable proximal aortic neck. With increasing experience, a greater proportion of patients with unfavorable neck anatomy are being offered EVR. This study aimed to evaluate outcomes in patients with challenging proximal aortic neck anatomy. METHODS: Prospectively collected data from 147 consecutive patients who underwent EVR between December 1997 and April 2005 were supplemented with a retrospective review of medical records and radiological images. Unfavorable anatomic features were defined as neck diameter >28 mm, angulation >60 degrees, circumferential thrombus >50%, and length <10 mm. Eighty-seven patients with 0 adverse features (good necks) were compared with 60 patients with one or more adverse features (hostile necks). RESULTS: Comparing the good neck with the hostile neck group, there were no significant differences in the incidence of primary technical success (p = 0.15), intraoperative adjunctive procedures (p = 0.22), early proximal type I endoleak (<30 days) (p = 1.0), late proximal type I endoleak (>30 days) (p = 0.57), distal type I endoleak (p = 0.40), type III endoleak (p = 0.51), secondary interventions (p = 1.0), aneurysm sac expansion (p = 0.44), or 30 day mortality (p = 0.70). The good neck group had a significantly increased incidence of type II endoleak (p = 0.023). By multivariate analysis, the incidence of intraoperative adjunctive procedures was significantly increased in the presence of severe angulation (p = 0.041, OR 3.08, 95% CI 1.05-9.04). CONCLUSION: Patients with severely hostile proximal aortic neck anatomy may be treated with EVR, although severely angulated necks require additional intraoperative procedures. Early outcomes are encouraging and suggest that indications for EVR may be expanded to include patients with hostile neck anatomy.

Challenges and strategies for improving pediatric immunizations in New Jersey.

Only through committed, comprehensive, and enthusiastic participation can this public health concern be resolved. The collaboration initiated through the CARE program and the Child Health Statewide Leadership Council is only the first step. Solving the problem will require the efforts of the entire New Jersey community.
