The 2023 Society for Vascular Surgery, American Venous Forum, and American Vein and Lymphatic Society clinical practice guidelines for the management of varicose veins of the lower extremities. Part II: Endorsed by the Society of Interventional Radiology and the Society for Vascular Medicine.

The Society for Vascular Surgery, the American Venous Forum, and the American Vein and Lymphatic Society recently published Part I of the 2022 clinical practice guidelines on varicose veins. Recommendations were based on the latest scientific evidence researched following an independent systematic review and meta-analysis of five critical issues affecting the management of patients with lower extremity varicose veins, using the patients, interventions, comparators, and outcome system to answer critical questions. Part I discussed the role of duplex ultrasound scanning in the evaluation of varicose veins and treatment of superficial truncal reflux.

Regionalization of Emergent Vascular Surgery for Patients With Ruptured AAA Improves Outcomes.

Objective: Safe and efficient endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysm (r-AAA) requires advanced infrastructure and surgical expertise not available at all US hospitals. The objective was to assess the impact of regionalizing r-AAA care to centers equipped for both open surgical repair (r-OSR) and EVAR (r-EVAR) by vascular surgeons.

Methods: A retrospective review of all patients with r-AAA undergoing open or endovascular repair in a 12-hospital region.

Anatomic characteristics of abdominal aortic aneurysms presenting with delayed rupture after endovascular aneurysm repair.

Objective: Endovascular aneurysm repair (EVAR) has become the mainstay of treatment for abdominal aortic aneurysms (AAAs) requiring repair. Delayed rupture after EVAR represents a rare but potentially fatal complication. The purpose of this study was to review the frequency and characteristics of patients presenting with secondary rupture and to define the relationship between rupture after EVAR and initial compliance with instructions for use (IFU).

Current state of the treatment of perforating veins.

Perforating veins may play a role in the development of chronic venous insufficiency and ulceration. There is renewed interest in minimally invasive treatments vs historic surgical options. Current indications for treatment, technical success, and evidence for clinical efficacy are summarized.

Practice patterns of adjunctive therapy for venous leg ulcers.

Objectives Venous leg ulcers (VLU) are the most severe clinical sequelae of venous reflux and post thrombotic syndrome. There is a consensus that ablation of refluxing vein segments and treatment of significant venous obstruction can heal VLUs. However, there is wide disparity in the use and choice of adjunctive therapies for VLUs.

Renal protection: preconditioning for the prevention of contrast-induced nephropathy.

As the numbers of interventional procedures are rising exponentially, identification of those patients at risk for renal complications has become even more important. Renal complications have been associated with increased morbidity and mortality after interventions. Risk factors have been studied to help identify those patients at increased risk for developing contrast-induced nephropathy.

Venous occlusive diseases in women.

Women have a high incidence of chronic venous disease. Venous occlusive disease can lead to significant morbidity and even death. Factors such as genetics, medications, and diseases can play a role in the development of venous thrombosis.

The impact of hemodynamic status on outcomes of endovascular abdominal aortic aneurysm repair for rupture.

Objective: To date, there are no published reports comparing hemodynamically (Hd)-stable and Hd-unstable patients with ruptured abdominal aortic aneurysms (r-AAAs) undergoing endovascular aneurysm repair (EVAR). This study evaluates outcomes of EVAR for r-AAA based on patient's Hd status

Methods: From 2002 to 2011, 136 patients with r-AAAs underwent EVAR and were categorized into two groups based on systolic blood pressure (SBP) measurements before EVAR: 92 (68%) Hd-stable (SBP ≥ 80 mm Hg) and 44 (32%) Hd-unstable (SBP <80 mm Hg for >10 minutes). All data were prospectively entered in a database and retrospectively analyzed.

Ruptured abdominal aortic aneurysm: endovascular program development and results.

Improvements in endovascular technology and techniques have allowed us to treat patients in ways we never thought possible. Today endovascular treatment of ruptured abdominal aortic aneurysms is associated with markedly decreased morbidity and mortality when compared to the open surgical approach, yet there are several fundamental obstacles in our ability to offer these endovascular techniques to most patients with ruptured aneurysms. This article will focus on the technical aspects of endovascular aneurysm repair for rupture, with particular attention to developing a standardized multidisciplinary approach that will help ones ability to deal with not just the technical aspects of these procedures, but also address some of the challenges including: the availability of preoperative CT, the choice of anesthesia, percutaneous vs.

Long-term outcomes of secondary procedures after endovascular aneurysm repair.

Purpose: This study evaluated the outcomes of secondary procedures after endovascular aneurysm repair (EVAR).

Methods: From 2002 to 2009, 1768 patients underwent EVAR for treatment of 1662 elective (94%) and 106 emergent (6%) infrarenal abdominal aortic aneurysm (AAA) with a variety of Food and Drug Administration-approved and commercially available stent grafts. Postoperative follow-up included clinical examination, pulse volume recording, duplex ultrasound imaging, and computed tomography and magnetic resonance angiography at 1, 6, and 12 months, and yearly thereafter.

Outcomes of planned celiac artery coverage during TEVAR.

Objective: Successful thoracic endovascular aneurysm repair (TEVAR) requires adequate proximal and distal fixation and seal. We report our experience of planned celiac artery coverage during endovascular repair of complex thoracic aortic aneurysms (TAA).

Methods: Since 2004, 228 patients underwent TEVAR under elective (n=162, 71%) and emergent circumstances (66, 29%).

Strategies to improve spinal cord ischemia in endovascular thoracic aortic repair: Outcomes of a prospective cerebrospinal fluid drainage protocol.

Purpose: Although endovascular repair of thoracic aortic aneurysm has been shown to reduce the morbidity and mortality rates, spinal cord ischemia remains a persistent problem. We evaluated our experience with spinal cord protective measures using a standardized cerebrospinal fluid (CSF) drainage protocol in patients undergoing endovascular thoracic aortic repair.

Methods: From 2004 to 2006, 121 patients underwent elective (n = 52, 43%) and emergent (n = 69, 57%) endovascular thoracic aortic stent graft placement for thoracic aortic aneurysm (TAA) (n = 94, 78%), symptomatic penetrating ulceration (n = 11, 9%), pseudoaneurysms (n = 5, 4%) and traumatic aortic transactions (n = 11, 9%).

Combined carotid endarterectomy and coronary artery bypass grafting in patients with asymptomatic high-grade stenoses: an analysis of 758 procedures.

Purpose: Surgical treatment of hemodynamically significant carotid artery stenoses has been well documented, especially in the asymptomatic patient. However, in those patients presenting with hemodynamically significant asymptomatic carotid artery disease who are to undergo cardiac surgery, optimal treatment remains controversial. In this study, we analyze our experience with patients who underwent synchronous carotid endarterectomy (CEA) and coronary artery bypass graft procedures (CABG) for hemodynamically significant (>70%) asymptomatic carotid artery stenosis and coronary artery disease (CAD).

Establishing a protocol for endovascular treatment of ruptured abdominal aortic aneurysms: outcomes of a prospective analysis.

Purpose: In our transition from elective abdominal aortic aneurysm (AAA) to emergent ruptured AAA (r-AAA) repair with endovascular techniques, we recognized that the availability of endovascularly trained staff in the operating rooms and emergency departments, and adequate equipment were the limiting factors. To this end, we established a multidisciplinary protocol that facilitates endovascular repair (EVAR) of r-AAA.

Methods: In January 2002, we instituted a multidisciplinary approach that included the vascular surgeons, emergency department physicians, anesthesiologists, operating room staff, radiology technicians, and availability of a variety of stent-grafts to expedite EVAR of r-AAAs.

Factors associated with abdominal compartment syndrome complicating endovascular repair of ruptured abdominal aortic aneurysms.

Background: Endovascular treatment of ruptured abdominal aortic aneurysms (r-AAAs) has the potential to offer improved outcomes. As our experience with endovascular repair of r-AAA evolved, we recognized that the development of abdominal compartment syndrome (ACS) led to an increase in morbidity and mortality. We therefore reviewed our experience to identify risk factors associated with the development of ACS.

Safety and efficacy of eversion carotid endarterectomy for the treatment of recurrent stenosis: 20-year experience.

Current options for treating recurrent carotid stenosis (RCS) include standard longitudinal arteriotomy and patch angioplasty with or without carotid endarterectomy (s-PCEA), carotid-carotid bypass, or carotid angioplasty and stent (CAS). Eversion carotid endarterectomy (e-CEA) is an effective procedure for treating primary carotid stenosis, yet it has not been reported for treating RCS. We evaluated the feasibility and outcome of e-CEA for treating of RCS in comparison to s-PCEA.

Outcome of concomitant renal artery reconstructions in patients with aortic aneurysm and occlusive disease.

The question remains as to whether patients presenting with aortoiliac occlusive disease (AIOD) or abdominal aortic aneurysms (AAAs) have similar outcomes when concomitant renal artery reconstructions are performed. In this study, we analyzed our experience with simultaneous aortic and renal reconstructions using a retroperitoneal approach. Over a 5-year period, all patients with either AAAs > 5 cm or symptomatic AIOD who were found to have high-grade renal artery stenosis and who underwent aortic reconstructions with concomitant renal revascularization were analyzed through our vascular surgery registry.

Does sac size matter? Findings based on surgical exploration of excluded abdominal aortic aneurysms.

Purpose: To prospectively examine the outcomes of excluded abdominal aortic aneurysms (AAA) that continue to expand without evidence of endoleak.

Methods: From 1984 to 1998, 1218 patients underwent operative retroperitoneal exclusion of AAA and aortoiliac reconstructions. During the procedure, the aneurysm sac was ligated proximally, as well as distally, which created an ideal in-vivo model of excluded AAA sacs with or without endoleaks.

Infrarenal abdominal aortic aneurysm repair via endovascular versus open retroperitoneal approach.

The beneficial effects of open surgical abdominal aortic aneurysm (AAA) repair via a left retroperitoneal approach have been established. We compared the short-term outcome of infrarenal AAA repair via an endovascular approach with that of an open retroperitoneal approach. From October 2001 to April 2003, patients with infrarenal AAA >5 cm were offered repair via an endovascular approach (group I) with a variety of industry-made stent grafts or with an open retroperitoneal surgical approach (group II).

Outcome of popliteal artery aneurysms after exclusion and bypass: significance of residual patent branches mimicking type II endoleaks.

Purpose: Popliteal aneurysms (PAs) often are treated with exclusion and bypass. However, excluded aneurysms can transmit systemic pressure from persistent flow through collateral arteries (endoleak), resulting in aneurysm growth and rupture. We used duplex ultrasound scanning for postoperative surveillance more than 2 years after PA repair with exclusion and bypass, to determine the presence of flow and aneurysm growth.

Effects of bilateral hypogastric artery interruption during endovascular and open aortoiliac aneurysm repair.

Purpose: Hypogastric artery interruption is sometimes required during aortoiliac aneurysm repair. We have not experienced some of the life-threatening complications of pelvic ischemia reported by others. Therefore we analyzed our experience to identify factors that help minimize pelvic ischemia with unilateral and bilateral hypogastric artery interruption.

Analysis of factors contributing to improved outcome for carotid endarterectomy.

Since carotid endarterectomy was revitalized following the North American Symptomatic Carotid Endarterectomy Trial and Asymptomatic Carotid Atherosclerosis Study, results have improved. However, types of carotid endarterectomy, indications, risk factors, surgical factors, techniques, and other treatment modalities may be associated with outcomes of carotid endarterectomy. The purpose of this study was to identify those factors in a broad-based carotid endarterectomy patient.

Outcome of aggressive surveillance colonoscopy in ruptured abdominal aortic aneurysm.

Purpose: Emergent repair of ruptured abdominal aortic aneurysms (rAAAs) is associated with high perioperative morbidity and mortality. One of the significant complications of this surgery is bowel ischemia. Reports detail mortality as high as 80% when this condition is realized.
