OBJECTIVE Unquestionably, the federal government has created financial incentives for vascular interventionists to perform procedures in their offices rather than in a hospital setting. While office venous ablations have been widely embraced by the vascular community, those involving the arterial system have not. One important reason may be related to the(More)
BACKGROUND The technique of balloon angioplasty of infrainguinal arteries requires standard arteriography and fluoroscopic guidance. We attempted to perform this procedure under duplex guidance to avoid the use of nephrotoxic contrast material and radiation exposure in patients with renal insufficiency. METHODS Over 16 months, 28 patients (17 men) with(More)
BACKGROUND Radiofrequency ablation (RFA) is a widely accepted alternative to high ligation with proximal stripping of the great saphenous vein (GSV) in the treatment of lower extremity venous insufficiency. This study compared short-term outcomes of two generations of (VNUS Closure) RFA catheters, ClosurePlus (CP) and ClosureFast (CF). METHODS From(More)
We have noted a significant incidence of pulmonary embolism (PE) and mortality associated with upper extremity deep venous thrombosis (UEDVT). Since there is an association between site of lower extremity DVT (LEDVT) and PE, we hypothesized that there might also be a correlation between site of UEDVT and PE with associated mortality. To further elucidate(More)
OBJECTIVE Following contemporary trend, various vascular interventions being performed in the office. We describe our office experience with radiofrequency ablation (RFA) of incompetent perforating veins (IPV) and duplex-guided balloon angioplasties of failing/nonmaturing arterio-venous fistulas (AVF). DUPLEX-GUIDED BALLOON ANGIOPLASTIES OF AVF: Eighteen(More)
BACKGROUND To examine the effect of office-based duplex-guided balloon-assisted maturation (DG-BAM) on arteriovenous fistula (AVF), we retrospectively analyzed our experience. METHODS Over the past 10 months, we performed 185 DG-BAMs (range, 1-8 procedures; mean, 3.7) in 45 patients (29 male, 16 female; mean age, 68.2 ± 12.8 years) with 31(More)
Endovascular repair of failing infrainguinal bypasses can effectively improve patency and limb salvage results in selected cases. We attempted to perform balloon angioplasties of 47 failing grafts in 3 patients under duplex guidance to eliminate or diminish the use of nephrotoxic contrast material and radiation exposure. The technical success was 98% (46/47(More)
Carotid artery balloon angioplasty and stenting (CBAS) is gaining popularity as an adequate alternative to carotid endarterectomy (CEA) in selected patients. Unfortunately, the substantial amount of contrast media used for CBAS, traditionally performed under fluoroscopic guidance, may impair renal function in patients with diabetes or ones with elevated(More)
Acute mesenteric ischemia is commonly treated by surgical exploration and open thrombectomy. Very few reports describe using newer, minimally invasive methods which utilize catheter-based mechanical and pharmacological thrombolysis. Herein, we report a case of acute superior mesenteric embolism successfully treated with AngioJet hydrodynamic mechanical(More)
PURPOSE The placement of central catheters is a common procedure. It is also associated with multiple known complications. One of the potential complications that carry high morbidity and morality is arterial puncture and cannulation. Herein, we describe five case reports of a central line that was inadvertently placed in the subclavian artery and(More)
