Influence of Carotid Endarterectomy on Choroidal Perfusion: The INFLATE Study.

Purpose: Patients with clinically significant carotid artery stenosis (CAS) undergoing carotid artery endarterectomy (CEA) were imaged with swept-source OCT angiography (SS-OCTA) imaging protocol to determine if there were changes in choroidal blood flow after surgery.

Design: Prospective observational study.

Participants: Patients with clinically significant CAS undergoing unilateral CEA.

An out of the box treatment for an infected pseudoaneurysm: Deep to superficial femoral artery transposition.

An infected pseudoaneurysm is a condition that has become more common in recent years, with the proliferation of endovascular intervention and the use of intravenous drugs. If left untreated, an infected pseudoaneurysm can progress to rupture, which can lead to life-threatening hemorrhage. No clear consensus has been reached among vascular surgeons regarding the management of infected pseudoaneurysms, and the literature describes a wide range of treatment techniques.

Feasibility of Intravascular Lithotripsy for the Treatment of Calcified Supra-Aortic Vessels: A Case Report and Literature Review.

Purpose: To report a case of coronary-subclavian steal syndrome (CSSS) due to a history of a left internal mammary artery (LIMA) to left anterior descending (LAD) artery coronary bypass (CABG) and a heavily calcified ostial left subclavian artery (LSA) occlusion, that was treated with intravascular lithotripsy (IVL) technique and to summarize the current trends of IVL treatment for supra-aortic vessels.

Case Report: A 64-year-old woman with progressive intermittent angina pectoris and a history of LIMA to LAD bypass underwent coronary angiography which demonstrated complete ostial occlusion of the LSA. Via brachial access, the patient underwent Shockwave IVL balloon treatment of the LSA and stent-graft implantation.

Suitability of current off-the-shelf devices for endovascular TAAA repair: a systematic review.

Introduction: The aim of the present study is to perform a systematic review of published papers regarding the suitability of the current off-the-shelf (OTS) devices for endovascular thoracoabdominal aortic aneurysm (TAAA) repair.

Evidence Acquisition: A systematic review of the MEDLINE database via PubMed was performed in March 2023. All studies reporting the outcomes of the three currently available OTS stent-grafts: the Zenith t-Branch (Cook Medical, Bloomington, IN, USA), the Gore Excluder thoracoabdominal branch endoprosthesis (TAMBE; W.

Common femoral adventitial cystic disease in a young female patient.

Adventitial cystic disease (ACD) is a rare condition that typically presents in young healthy men with symptoms of claudication. ACD is characterized by formation of a mucinous cyst within the adventitia of a blood vessel, usually in the popliteal artery, causing compression of the vessel's lumen and leading to reduced flow and symptoms of claudication. We have presented a rare case of ACD of the common femoral artery in a young female patient that was treated successfully with resection and femoral vein graft interposition reconstruction.

A novel endovascular treatment for transcatheter aortic valve embolization.

In the present report, we have described the case of an 82-year-old obese man who had required transcatheter aortic valve replacement to treat severe symptomatic aortic stenosis. During implantation, the balloon-mounted valve became dislodged and embolized to the ascending aorta. A second valve was successfully implanted after several failed attempts to reposition the first one into the aortic annulus.

Long-term renin-angiotensin blocking therapy in hypertensive patients with normal aorta may attenuate the formation of abdominal aortic aneurysms.

Renin-angiotensin system (RAS) has been implicated in the pathogenesis of abdominal aortic aneurysm (AAA). Angiotensin II type 1 receptor blocker (ARB), when given with angiotensin II prevents AAA formation in mice, but found ineffective in attenuating the progression of preexisting AAA. This study was designed to evaluate the effect of chronic RAS blockers on abdominal aortic diameter in hypertensive patients without known aortic aneurysm.

Endovascular repair of complex aortic aneurysms.

Background: Surgery for complex aortic aneurysms (thoracoabdominal, juxtarenal and pseudoaneurysms) is associated with a high morbidity and mortality rate. Branched and fenestrated stent grafts constitute a new technology intended as an alternative treatment for this disease.

Objectives: To describe a single-center experience with fenestrated and branched endografts for the treatment of complex aortic aneurysms.

The deep femoral artery, a readily available inflow vessel for lower limb revascularization: a single-center experience.

The deep femoral artery (DFA) offers several advantages as an inflow vessel in lower-extremity bypasses. We report a single-center experience using the DFA as an inflow artery for lower-extremity revascularization. We reviewed all patients who underwent a lower-extremity bypass utilizing the DFA as the inflow vessel.

Aortic root surgery in Marfan syndrome.

Background: As the shortcomings of the Bentall operation and its variants in the Marfan syndrome have become apparent, the recent cusp-sparing techniques (remodeling or reimplantation) bear promise of better mid-term and long-term outcomes.

Objective: To examine the results of aortic root surgery in patients with Marfan syndrome.

Methods: During the period March 1994 to September 2007, 220 patients underwent aortic valve-sparing surgery; 20 were Marfan patients (group 1) who were compared with another 20 Marfan patients undergoing composite aortic root replacement (group 2).

[Aortic valve sparing surgery].

Background: Over the past 20 years, a series of procedures have been designed to reconstruct the aortic root of patients with aortic insufficiency, in whom the pathology and hence, the surgery, spares the valve leaflets. The objective of this current study was to evaluate our midterm results comparing the reimplantation technique with the remodeling technique in patients with aortic regurgitation due to aortic dissection, aortic root and ascending aortic aneurysms.

Patients And Methods: During the years 1993 and 2006 we operated on 209 patients with aortic regurgitation secondary to dilatation of the aortic root or ascending aorta with or without aortic dissection.

Improved viability and reduced apoptosis in sub-zero 21-hour preservation of transplanted rat hearts using anti-freeze proteins.

Background: Freeze-tolerant fish survive sub-zero temperatures by non-colligatively lowering the freezing temperature of their body fluids using anti-freeze proteins (AFPs). We sought to evaluate and compare the effects of prolonged sub-zero cryopreservation of transplanted rat hearts using AFP I or AFP III.

Methods: Two heterotopic rat heart transplantation protocols were used.

Subzero nonfreezing cryopresevation of rat hearts using antifreeze protein I and antifreeze protein III.

The purpose of the present study was to evaluate whether AFPs protect the heart from freezing and improve survival and viability in subzero cryopreservation. Hearts were subject to 5 preservation protocols; University of Wisconsin solution (UW) at 4 degrees C, UW at -1.3 degrees C without nucleation, UW at -1.
