Percutaneous Orthotopic IVC Construction in a Pediatric Patient with Symptomatic IVC Agenesis

Marc H. Schiffman, Joshua Cornman-Homonoff, Thomas A. Sos

CardioVascular and Interventional Radiology > 2019 > 42 > 2 > 308-312

Inferior vena cava agenesis is an uncommon condition usually attributed to embryologic dysgenesis. When symptomatic, unprovoked deep venous thrombosis and/or lower extremity venous congestion are the most frequent manifestations. Its rarity has precluded consensus regarding appropriate management. Symptomatic chronic venous congestion requires surgical construction of auxiliary venous pathways, which...

Atherosclerotic renal artery stenosis in the post-CORAL era part 1: the renal penumbra concept and next-generation functional diagnostic imaging

Alan Alper Sag, Ibrahim Inal, John Okcuoglu, Patrick Rossignol, more

Journal of the American Society of Hypertension > 2016 > 10 > 4 > 360-367

After three neutral trials in which renal artery stenting failed to improve renal function or reduce cardiovascular and renal events, the controversy surrounding diagnosis and treatment of atherosclerotic renal artery stenosis and renovascular hypertension has led to paradigm shifts in the diagnostic algorithm. Noninvasive determination of earlier events (cortex hypoxia and renal artery hemodynamic...

Atherosclerotic renal artery stenosis in the post-CORAL era part 2: new directions in Transcatheter Nephron Salvage following flawed revascularization trials

Alan Alper Sag, Thomas A. Sos, Caghan Benli, Oguzhan Sal, more

Journal of the American Society of Hypertension > 2016 > 10 > 4 > 368-377

Unlike endovascular therapeutic studies for atherosclerosis in many other vascular beds, major trials regarding endovascular renovascular revascularization have resulted in a stagnating equipoise. However, every major trial completed for this topic thus far has suffered from major methodological flaws that limit the validity and external generalizability of their results. Furthermore, certain patient...

Brachial Artery Access

Kyungmouk Steve Lee, Thomas A. Sos

Techniques in Vascular and Interventional Radiology > 2015 > 18 > 2 > 87-92

Low brachial artery access is a safe alternative approach for the interventionalist when the femoral artery approach is not feasible or desirable. One important advantage of upper extremity access is the favorable route of entry from above into the caudally oriented visceral arteries. Although the risk of complications is low for experienced operators, meticulous attention to technique and knowledge...

Renal Artery Stenosis: Imaging Options, Pitfalls, and Concerns

Hong Lei Zhang, Thomas A. Sos, Priscilla A. Winchester, Jing Gao, more

Progress in Cardiovascular Diseases > 2009 > 52 > 3 > 209-219

Renal artery stenosis can be diagnosed with multiple imaging modalities, each one having different risk vs accuracy tradeoffs. Catheter angiography with pressure gradient measurements is the definitive gold standard but also the most invasive and thus reserved primarily for imaging at the time of renal revascularization. Ultrasonography is the safest and least expensive but also the least accurate...

To formulate comprehensive recommendations for the diagnostic approach to patients with suspected pulmonary embolism, based on randomized trials.Diagnostic management recommendations were formulated based on results of the Prospective Investigation of Pulmonary Embolism Diagnosis II (PIOPED II) and outcome studies.The PIOPED II investigators recommend stratification of all patients with suspected...

Ostial renal artery stent placement in patients 75 years of age or older

Michael J. Bloch, David A. Trost, James Whitmer, Thomas G. Pickering, more

American Journal of Hypertension > 2001 > 14 > 10 > 983-988

Renal artery stent placement has been shown to improve blood pressure (BP) and stabilize renal function in patients with atherosclerotic renovascular disease. However, limited data are available in patients =<75 years of age.We analyzed the prestent characteristics and clinical outcomes of patients aged =<75 years who underwent renal artery stenting at our institution. We compared these data...

Treatment of atheroembolization with corticosteroids

Samuel J. Mann, Thomas A. Sos

American Journal of Hypertension > 2001 > 14 > 8 > 831-834

Aortic atheroembolization is a feared complication of invasive procedures such as arteriography, often leading to devastating complications including renal insufficiency. To date, even in cases with evolving renal failure, there is no recommended treatment. This case report describes the successful treatment with corticosteroids of a patient with deteriorating renal function after renal arteriography...

Transcatheter Interventions for the Treatment of Peripheral Atherosclerotic Lesions: Part I

Krishna Kandarpa, Gary J. Becker, M.G. Myriam Hunink, Thomas O. McNamara, more

Journal of Vascular and Interventional Radiology > 2001 > 12 > 6 > 683-695

Transcatheter endovascular procedures are increasingly used to treat symptomatic peripheral atherosclerosis. This two-part review identifies the existing evidence supportive of the application of transcatheter treatments for peripheral atherosclerotic lesions. The first part addresses the treatment of obstructive lesions that cause limb claudication and critical ischemia, renovascular hypertension...

Type B Aortic Dissection Complicating Renal Artery Angioplasty and Stent Placement

Michael J. Bloch, David W. Trost, Thomas A. Sos

Journal of Vascular and Interventional Radiology > 2001 > 12 > 4 > 517-520

Percutaneous renal artery stent placement has been demonstrated to improve blood pressure control and stabilize renal function in patients with atherosclerotic renal artery disease. However, this procedure is not without risk of significant morbidity, and its effectiveness, as compared to alternative treatments, has not been adequately established. The authors report a case of acute type B aortic...

Michael J. Bloch, David W. Trost, Thomas G. Pickering, Thomas A. Sos, more

American Journal of Hypertension > 1999 > 12 > 1 > 1-7

Pulmonary edema and congestive heart failure (both referred to here as PE) have been reported to be complications of bilateral renal artery stenosis or unilateral stenosis in a solitary functioning kidney (both referred to as BRAS). The goals of this study were to determine whether a history of PE was more common in patients with BRAS than in those with unilateral stenosis and a normal contralateral...

To accurately determine the in vivo orientation of the origin of the renal arteries from the aorta relative to a fluoroscopic bony landmark for optimal diagnostic arteriography and renal artery stent placement.One hundred sixty abdominal computed tomography (CT) scans of patients in eight age groups (20–90 years) were reviewed to determine the angle of the origins of the renal arteries from the aorta...

Priscilla A. Winchester, Howard M. Lee, Neil M. Khilnani, Yi Wang, more

Journal of Vascular and Interventional Radiology > 1998 > 9 > 6 > 891-899

To perform a preliminary evaluation of the diagnostic accuracy of contrast-enhanced, two-dimensional (2D) magnetic resonance (MR) digital subtraction angiography (DSA) of the lower extremity by comparison with x-ray angiography (XRA).Forty lower extremities in 22 patients were imaged at multiple levels with both XRA and 2D MR DSA. Images were retrospectively analyzed by three radiologists in a randomized...
