ANNALS OF VASCULAR SURGERY. Primary Stenting of TASC C and D Femoropopliteal Lesions: Results of the STELLA Register at 30 Months

Jean-Michel Davaine , Julien Quérat , Béatrice Guyomarch , Alain Costargent , Philippe Chaillou , Philippe Patra , Yann Gouëffic

The 1-year results of the prospective register STELLA suggested that primary stenting of long femoropopliteal (FP) lesions (≥15-cm) was a sure and effective treatment. However, the long-term results of this technique remain unknown.

ANNALS OF VASCULAR SURGERY. Catheter-directed Thrombolysis for Severe Pulmonary Embolism in Pediatric Patients

Aarti C. Bavare, Swati X. Naik , Peter H. Lin , Mun Jye Poi , Donald L. Yee , Ronald A. Bronicki , Joseph X. Philip , Moreshwar S. Desai

Catheter-directed thrombolytic (CDT) therapies for severe pulmonary embolism (PE) have been shown to be effective and safe when compared with systemic thrombolysis in adults. Pediatric studies assessing efficacy and safety of CDT for PE are lacking. Hence, our aim was to review CDT as a therapy for pediatric PE.

ANNALS OF VASCULAR SURGERY. Current Results of a Combined Endovascular and Open Approach for the Treatment of Aortoesophageal and Aortobronchial Fistulae

Andrea Kahlberg, Yamume Tshomba , Enrico M. Marone , Renata Castellano , Germano Melissano , Roberto Chiesa

Aortoesophageal (AEF) and aortobronchial (ABF) fistulae are uncommon but invariably fatal if left untreated. Mortality rates of open surgery remain prohibitive. Thoracic endovascular aortic repair (TEVAR) was shown to be a valid alternative to control bleeding in emergency, allowing a reduction of perioperative mortality. However, it entails a significant risk of late sequelae, namely endograft contamination and sepsis, related to the untreated esophageal leak. The aim of this study is to present initial results of a combined “hybrid” (endovascular and open) strategy to treat AEF and ABF.

ENDOVASCULAR TODAY. Utility of Procedural Checklists in SFA Interventions

By Michael S. Hong, MD, and David L. Dawson, MD

The use of checklists is a simple and cost-effective strategy to reduce errors. In medical practice, checklist use improves patient outcomes. Widespread use of the “Surgical Safety Checklist,” developed in 2008 by the World Health Organization as part of the “Safe Surgery Saves Lives” project, confirmed this.1 Over a period of several years, multiple studies—including a large meta-analysis involving more than 37,000 patients—have demonstrated a reduction in major complications after implementation of surgical checklists.2-4

ENDOVASCULAR TODAY. Gonadal Vein Embolization

By Sandeep Bagla, MD

Fifteen percent of all outpatient gynecologic visits and 30% of patients who present with pelvic pain are secondary to pelvic congestion syndrome (PCS). Unfortunately, this disease is often overlooked, with patients frequently undergoing an exhaustive evaluation before being diagnosed with PCS. Pelvic congestion with varices was first described more than 150 years ago, and the symptoms were considered psychosocial more than 50 years ago;1 even still, there are often delays in diagnosis because general practitioners are not aware of the syndrome and typically refer patients to psychologists or other counselors. The underlying pathophysiology of PCS was first described around the same time, with further anatomical understanding developed in more recent decades. Negative psychosocial associations with the term pelvic congestion syndrome has led to pelvic venous insufficiency being the preferred term for describing the underlying pathophysiology of the condition.1

ENDOVASCULAR TODAY. Endovascular Approaches to Pulmonary Thromboembolic Disease

By Ronnie C. Chen, MD; Scott Genshaft, MD; Ramsey Al-Hakim, MD; John Moriarty, MD; and Christopher Loh, MD

Pulmonary thromboembolic disease is a significant problem accounting for one-third of patients with venous thromboembolism. Approximately 600,000 people in the United States present with pulmonary embolism annually, resulting in 50,000 to 200,000 deaths per year.1 Early mortality and adverse outcomes are linked to those with high- and intermediate-severity disease, and risk stratification plays a pivotal role in triaging patients for treatment. The two main factors predicting disease severity are the volume of pulmonary arterial occlusion and the presence of pre-existing cardiopulmonary disease. Patients with underlying conditions such as chronic obstructive pulmonary disease, ischemic heart disease, and pulmonary arterial hypertension have decreased cardiopulmonary reserve and can tolerate a lesser degree of pulmonary arterial occlusion before going into hemodynamic shock.

ENDOVASCULAR TODAY. Splanchnic Venous Thrombosis: Challenges and Opportunities

By Mehran Midia, MD, FRCP(C), and Mahmood K. Razavi, MD, FSIR

Isolated mesenteric venous thrombosis without concomitant extrahepatic portal vein thrombosis or a splenic vein thrombosis is rare.1 Therefore, we will focus on splanchnic venous thrombosis (SVT), particularly portal and mesenteric vein thrombosis. Comprehensive management of secondary portal hypertension due to chronic SVT is beyond the scope of this article.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Effect of Pitavastatin on Preventing Ischemic Complications with Carotid Artery Stenting: A Multicenter Prospective Study—EPOCH-CAS Study

Periprocedural ischemic stroke is one problem associated with carotid artery stenting (CAS). This study was designed to assess whether preoperative statin therapy reduces the risk of periprocedural ischemic complications with CAS.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. A Randomized, Double-Blind, Placebo-Controlled Study of Preemptive Oral Oxycodone with Morphine Patient-Controlled Anesthesia for Postoperative Pain Management in Patients Undergoing Uterine Artery Embolization for Symptomatic Uterine Fibroids

Alex H. Konstantatos, Helen Kavnoudias, James R. Stegeman, Dana Boyd, Maryann Street, Michael Bailey, Stuart M. Lyon, Kenneth R. Thomson

To evaluate the analgesic efficacy of oral premedication of oxycodone in a group of patients undergoing elective uterine artery embolization under sedation for fibroid disease.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Factors Associated with Aggravation of Esophageal Varices after B-RTO for Gastric Varices

Atsushi Jogo, Norifumi Nishida, Akira Yamamoto, Hiroto Matsui, Tohru Takeshita, Yukimasa Sakai, Toshiyuki Matsuoka, Kenji Nakamura, Yukio Miki

To retrospectively evaluate risk factors for aggravation of esophageal varices (EV) within 1 year after balloon-occluded retrograde transvenous obliteration (B-RTO) of gastric varices (GV) and to clarify suitable timing for upper endoscopy to detect EV aggravation after B-RTO.
