Aoife Kilcoyne, Debra A Gervais
Percutaneous urologic biopsy is a safe and effective technique and can comprise a significant proportion of the daily workload of the interventional radiologist. This article discusses the indications and rationale for the performance of renal, ureter, and bladder biopsy as well as the approach to performing such biopsies, pitfalls, and potential complications.

Renal transplantation is the therapy of choice in patients with end stage renal disease. Although transplant rejection remains the most common complication after renal transplantation, vascular anatomical complications occur in 1%-23% of renal transplant recipients. Interventional radiologists play an important role in the management of these complications. This review discusses the role of image-guided interventions within the context of multidisciplinary patient management. Particular emphasis is given to anatomical considerations unique to this patient population, techniques used for image-guided interventions, and outcomes of image-guided interventions...

Nonvascular complications represent a significant source of morbidity following renal transplantation and can be seen in up to 20% of patients. Postoperative problems include urinary tract obstruction or leakage and the development of peritransplant fluid collections. Interventional radiologists play a key role in the management of these patients. Image-guided interventions are used to identify the underlying anatomical problem, relieve immediate symptoms, and allow planning for long-term resolution. In this article, we review the urinary tract anatomy relevant to renal transplantation, procedural techniques for image-guided urinary tract interventions and interventions on peritransplant fluid collections, and expected outcomes following image-guided interventions...

Renal artery stenosis is a potentially reversible cause of hypertension, and transcatheter techniques are essential to its treatment. Angioplasty remains a first-line treatment for stenosis secondary to fibromuscular dysplasia. Renal artery stenting is commonly used in atherosclerotic renal artery stenosis, although recent trials have cast doubts upon its efficacy. Renal denervation is a promising procedure for the treatment of resistant hypertension, and in the future, its indications may expand.

REVIEW
Raja S Ramaswamy, Michael D Darcy
Renal artery embolization (RAE) for a variety of indications has been performed for several decades. RAE techniques have been refined over time for clinical efficacy and a more favorable safety profile. Owing to improved catheters, embolic agents for precise delivery, and clinical experience, RAE is increasingly used as an adjunct to, or as the preferred alternative to surgical interventions. The indications for RAE are expanding for many urologic and medical conditions. In this article, we focus on the role and technical aspects of RAE in the treatment of renal masses and traumatic renal injuries...

Small renal malignancies are commonly treated with nephron-sparing procedures including partial nephrectomy and percutaneous ablation. Although these procedures offer faster patient recovery and preserve renal function, a variety of complications can occur. Here, we review vascular and nonvascular complications associated with nephron-sparing renal mass treatments and discuss options for minimally invasive image-guided management.

Interventional radiologists are commonly called upon to manage patients with benign and malignant ureteral pathologic conditions. Unfortunately, treatments for both cure and palliation can be fraught with problems causing patients to be undesirably maintained with lifelong catheters. This review describes outcomes for antegrade and retrograde therapeutic options and techniques for patients with most types of ureteral pathologic conditions that the interventional radiologist would encounter in practice.

REVIEW
Raymond H Thornton, Anne M Covey
Urinary drainage procedures are used to treat a wide range of clinical situations including pyonephrosis, preservation of renal function in patients with ureteral obstruction, as a means to access the collecting system for stone retrieval or lithotripsy and to divert urine from a distal leak or fistula. Several different drainage devices are available and include those that provide obligatory external drainage (nephrostomy), both internal and external drainage (nephroureteral stent) and internal drainage (double-J stent)...

Joseph J Zechlinski, Robert A Hieb
Lumbar sympathectomy was historically a mainstay of treatment for arterial occlusive disease and other vasospastic disorders, before the development of contemporary arterial reconstructive procedures either by surgical or endovascular means. Today, percutaneous methods of sympathetic blockade are possible using chemical neurolytic or ablative modalities. Lumbar sympathetic neurolysis is generally reserved for those patients with ischemic rest pain in the setting of nonreconstructable arterial occlusive disease, although patients with complex regional pain syndrome, peripheral neuralgia, vasospastic disorders, and various other disease states such as plantar hyperhydrosis may also benefit...

Peripheral vascular disease (PVD) is a devastating medical problem that may lead to significant life alterations for patients, from simply limiting their daily activities to potential loss of limbs and eventual demise. Superficial femoral and popliteal arteries are significantly common locations for PVD sequelae to present itself, and owing to their length and mobile nature, treatment of these segments are quite challenging. Indications for PVD treatment include lifestyle-limiting claudication that is not responding to medical management, ischemic rest pain, nonhealing ulcers, and lower extremity gangrene...

Peripheral arterial disease (PAD) affects over 8 million people in the United States alone. Although great strides have been made in reducing the burden of cardiovascular disease the prevalence of PAD is expected to rise with the age of global population. PAD characterized by narrowing of arterial blood can be asymptomatic or cause limb threatening claudication. It has been classically treated with bypass, but these techniques have been supplanted by endovascular therapy. Plain old balloon angioplasty has been successful in helping revascularize lesions, but its effect has not been durable because of restenosis...

Endovascular management of chronic total occlusions (CTO) can be challenging both from decision-making and technical perspectives. Successful treatment and management of a CTO requires the operator to have an understanding of the salient imaging findings, a thorough knowledge of the various technical challenges of the procedure, and comprehension of the importance and necessity of long-term clinical management. This article outlines a general approach to endovascular management of lower limb CTOs and discusses indications, techniques, potential complications, and therapeutic options of the procedure...

Peripheral atherectomy is a class of procedures that is rapidly increasing in volume. Multiple classes of devices exist, and newer variants are added to the market annually. The devices see wide application for de novo lesions, in-stent restenosis, and adjunctive therapy for drug-coated balloons. The body of evidence supporting atherectomy is less robust than for many other peripheral therapies. The frequency and severity of complications from atherectomy can be significant compared with angioplasty and stenting, and familiarity with preventative and bailout techniques is essential for the interventionalist...

Vascular interventionalists continue to expand the scope and breadth of endovascular procedures that we offer to our patients. However, we often have to overcome various anatomical and technical challenges to deliver an endovascular device. This article should give the modern interventionalist an array of technical tips and tricks to enable them to overcome various challenging anatomical features such as vessel tortuosity, vascular calcifications, and increasing abdominal pannus. We also hope to elucidate alternative accesses such as radial access, pedal access, popliteal access, and direct stent access as well as direct aortic access...

REVIEW
Kyle J Cooper, Constantino Peña, James Benenati
Critical limb ischemia is a condition that has increased in prevalence and carries a high degree of morbidity. Although endovascular therapy for treatment of patients with critical limb ischemia has undergone significant advances with improved outcomes over the past decade, these patients often have multilevel disease, and it may take weeks or months for ulceration healing. For this reason, the acceptable therapeutic end points during and immediately following revascularization remain somewhat obscure. There are multiple tools available to guide the treating vascular specialist in this regard...

Critical limb ischemia (CLI) has a high rate of major amputation and mortality due to advance systemic cardiovascular disease. The goals of treating patients with CLI not only include the prevention of limb loss but also to relieve pain, improve quality of life, and prevent death. A multidisciplinary team approach to treating patients with CLI improves limb salvage rates by helping to tailor the best intervention for these patients. In addition, a multidisciplinary team can help address cardiovascular risk modification and wound management to help in decreasing mortality and increase amputation-free survival...

We report a case of calcaneal osteomyelitis that was surgically resected from a patient with diabetes and peripheral vascular disease. A 91-year-old male with history of type 2 diabetes, peripheral vascular disease, balloon angioplasty, and recent (2 months ago) stent of the superficial femoral artery presented to the emergency department with a left heel wound infection probed to bone. The patient reported having been on intravenous Zosyn for several months via an outside infectious disease provider for clinical suspicion of osteomyelitis, but noted no improvement...

REVIEW
Anahita Dua, Cheong J Lee
With a rise in the aging popluation, the prevalence of peripheral arterial disease (PAD) is markedly increasing. The overall disease prevalence of PAD is in the range of 3%-10%, which increases to 15%-20% in persons older than 70 years of age. Given this upward trend in disease prevalence, the economic and societal burden of PAD would be considerable. The subgroup of patients who develop critical limb ischemia (CLI) represents the most challenging population to manage medically, surgically, and endovascularly...
