JOURNAL OF VASCULAR SURGERY. Renal function changes after snorkel/chimney repair of juxtarenal aneurysms

Jason T. Lee, MD, Vinit N. Varu, MD, Kenneth Tran, BS, Ronald L. Dalman, MD

Objective: The snorkel approach for endovascular aneurysm repair (EVAR) has been found to be a safe and viable alternative to open repair for juxtarenal abdominal aortic aneurysms with good short-term outcomes. Concerns about long-term durability and renal branch patency with this technique have been raised with the increasing availability of fenestrated devices. We sought to evaluate renal function changes in patients undergoing “snorkel” EVAR (sn-EVAR).

JOURNAL OF VASCULAR SURGERY. Endovascular aortic aneurysm repair surveillance may not be necessary for the first 3 years after an initially normal duplex postoperative study

Douglas A. Troutman, DO, Mohammed Chaudry, MD, Matthew J. Dougherty, MD, Keith D. Calligaro, MD

Objective: We have previously shown that duplex ultrasonography (DU) may replace computed tomography angiography (CTA) as the primary surveillance tool for endovascular aortic aneurysm repair (EVAR). Current Society for Vascular Surgery practice guidelines suggest that if CTA does not document endoleak, aneurysm sac enlargement, or limb stenosis by 12 months after EVAR, surveillance studies may be performed annually. The purpose of this study was to determine whether the time to the second surveillance DU study can be safely postponed to 3 years after EVAR if the initial study finding is normal.

JOURNAL OF VASCULAR SURGERY. Impact of intraoperative adverse events during branched and fenestrated aortic stent grafting on postoperative outcome

Frédéric Cochennec, MD, Hicham Kobeiter, MD, Manj S. Gohel, MD, Marek Majewski, MD, Jean Marzelle, MD, Pascal Desgranges, MD, Eric Allaire, MD, PhD, Jean Pierre Becquemin, MD

Objective: Fenestrated and branched endovascular devices are increasingly used for complex aortic diseases, and despite the challenging nature of these procedures, early experiences from pioneering centers have been encouraging. The objectives of this retrospective study were to report our experience of intraoperative adverse events (IOAEs) during fenestrated and branched stent grafting and to analyze the impact on clinical outcomes.

JOURNAL OF VASCULAR SURGERY. The impact of endovascular aneurysm repair on aortoiliac tortuosity and its use as a predictor of iliac limb complications

James Coulston, MSc, FRCS, Amy Baigent, MBBS, Haran Selvachandran, Steven Jones, MRCS, Francesco Torella, MD, FRCS, Robert Fisher, MD, FRCS

Objective: Aortoiliac tortuosity is often cited subjectively as a causative factor in iliac limb complications after endovascular aneurysm repair (EVAR); however, evidence on this subject is poor. The aim of this study was to investigate the impact of stent grafting on aortoiliac tortuosity and to explore the role of the tortuosity index (TI) as a predictor of iliac limb complications after EVAR.

JOURNAL OF VASCULAR SURGERY. Comparison of the impact of open and endovascular abdominal aortic aneurysm repair on renal function

Athanasios Saratzis, MBBS, MRCS, PhD, Pantelis Sarafidis, MD, MSc, PhD, Nikolaos Melas, MD, PhD, Harmeet Khaira, MBChB, MD, FRCS

Objective: The impact of any intervention on renal function is a crucial determinant of outcome. Open (OR) and endovascular (EVAR) abdominal aortic aneurysm (AAA) repair can affect renal function during the short and longer term. This study aimed to directly compare the effect of those different types of aneurysm repair during a period of 2 years.

JOURNAL OF VASCULAR SURGERY. Pelvic venous reflux is a major contributory cause of recurrent varicose veins in more than a quarter of women

Alice M. Whiteley, Daniel C. Taylor, BSc, Scott J. Dos Santos, Mark S. Whiteley, MS, FRCS (Gen)

Background: Leg varicose veins are associated with pelvic venous reflux in approximately 20% of women who have had children. However, most venous units do not routinely look for pelvic venous reflux or treat it. We aimed to investigate what proportion of patients with recurrent varicose veins and a history of open surgery have pelvic venous reflux as a major contributing cause of their recurrence.

JOURNAL OF VASCULAR SURGERY. Calf volume changes with venous occlusion air plethysmography in assessment of patients after deep venous thrombosis

Christopher R. Lattimer, MBBS, FRCS, MS, FDIT, PhD, George Geroulakos, MD, FRCS, PhD, Evi Kalodiki, MD, PhD, FRCS

Background: This is an analysis of the hemodynamic response of post-thrombotic legs to a sustained thigh compression and quick-release maneuver. This is an integral part of the investigation of venous occlusion plethysmography that has been promoted as a way of assessing the venous return. The aim was to quantify the venous volume changes in patients after deep venous thrombosis (DVT) and to determine whether refluxing legs differed from obstructed legs.

JOURNAL OF VASCULAR SURGERY. Measurement of calf muscle oxygenation during light-intensity exercise in patients with post-thrombotic syndrome

Takashi Yamaki, MD, Hisato Konoeda, MD, Atsuyoshi Osada, MD, Atsumori Hamahata, MD, Taro Kono, MD, Kazutaka Soejima, MD, Motohiro Nozaki, MD, Hiroyuki Sakurai, MD

Background: Near-infrared spectroscopy (NIRS) provides continuous noninvasive monitoring of changes in the levels of oxygenated hemoglobin (O2Hb) and deoxygenated hemoglobin (HHb) in tissues. The purpose of this study was to investigate changes in calf muscle O2Hb and HHb levels during standing and exercise in the follow-up of deep venous thrombosis (DVT).

JOURNAL OF VASCULAR SURGERY. Bedside inferior vena cava filter placement by intravascular ultrasound in critically ill patients is safe and effective for an extended time

Roan J. Glocker, MD, Oluwafunmi Awonuga, MD, Zdenek Novak, MD, Benjamin J. Pearce, MD, Mark Patterson, MD, Thomas C. Matthews, MD, William D. Jordan, MD, Marc A. Passman, MD

Background: Bedside inferior vena cava filter (IVCF) placement by intravascular ultrasound (IVUS) guidance has previously been shown to be a safe and effective technique, especially for critically ill patients, with initial experience of a prospectively implemented algorithm. The purpose of this study was to evaluate the effectiveness of IVUS-guided filter placement in critically ill patients with experience now extending out 5 years from implementation.

JOURNAL OF VASCULAR SURGERY. Reflux in the below-knee great saphenous vein can be safely treated with endovenous ablation

Shaun M. Gifford, MD, Manju Kalra, MBBS, Peter Gloviczki, MD, Audra A. Duncan, MD, Gustavo S. Oderich, MD, Mark D. Fleming, MD, Scott Harmsen, MS, Thomas C. Bower, MD

Background: Intervention on the great saphenous vein (GSV) has traditionally been limited to the above-knee (AK-GSV) segment for fear of saphenous neuralgia in spite of incompetence demonstrated in the below-knee (BK-GSV) segment. Residual symptoms and need for reintervention are reported to result in nearly half the patients if the refluxing BK-GSV is ignored. Experience with endovenous ablation of the BK-GSV at the time of AK-GSV treatment is sparsely reported in the literature. The aim of this study was to evaluate the safety of endovenous ablation of the refluxing BK-GSV.

EUROPEAN JOURNAL OF VASCULAR AND ENDOVASCULAR SURGERY. Polytetrafluoroethylene Covered Stent Placement for Focal Occlusive Disease of the Infrarenal Aorta

F.A.B. Grimme, M.M.P.J. Reijnen, K. Pfister, J.M. Martens, P. Kasprzak
