Popliteal artery aneurysm

INTRODUCTION: Duplex ultrasound (DUS) is the modality of choice for surveillance of popliteal artery aneurysms (PAAs). However, noninvasive vascular laboratories have no standard guidelines for reporting results. This study assessed reports of PAA DUS for inclusion of information pertinent to operative decision-making and timing of surveillance. METHODS: This study was a retrospective review of a multi-institutional repository that was queried for all patients with a PAA from 2008 to 2022 and confirmed via manual chart review...

Exostosis (also known as osteochondroma) is the most common benign bony lump of young people, usually arising at the distal femur. Vascular complications associated with exostoses are rare and include true aneurysm or pseudoaneurysm formation, deep vein thrombosis, arteriovenous fistula, and arterial insufficiency of the limbs. Few case reports describe pseudoaneurysms resulting from exostoses in mature adults, and no consensus has been reached regarding the optimal therapy. We report the case of a 51-year-old male patient complaining of persistent right thigh pain with a pulsatile mass and right calf swelling, without a history of trauma or hereditary multiple exostoses...

A persistent sciatic artery is a rare vascular anomaly that is prone to early atherosclerotic development and aneurysmal degeneration. Repair of the degenerative aneurysm is critical because it can lead to rupture, thrombosis, distal embolization, and sciatic nerve damage from compression. We report a case of a symptomatic unilateral persistent sciatic artery fusiform aneurysm that was treated using a simultaneous open surgical and endovascular approach. The patient underwent right common femoral to below-knee popliteal artery bypass and percutaneous endovascular embolization of the right sciatic artery aneurysm...

OBJECTIVE: True superficial femoral artery aneurysms (SFAAs) are rare and traditionally treated by open repair. However, the endovascular approach excluding the aneurysm sac with a covered stent may be an alternative. This study aimed to compare the outcomes of the open and endovascular repair of SFAAs. METHODS: This is a retrospective, observational, monocentric study. The main endpoints were: technical success, limb salvage and primary patency rate, and hospitalisation time...

Isolated nonruptured profunda femoris artery (PFA) aneurysms are exceedingly rare. We present the case of an 80-year-old man who initially presented with a large pulsatile mass in the right groin. Computed tomography angiography identified a giant 6-cm PFA aneurysm. This was a truly isolated PFA aneurysm without any evidence of concomitant abdominal aortic or popliteal aneurysms. Potential surgical options included reconstruction with an interposition graft, endovascular coil embolization, and aneurysmal ligation...

Popliteal artery entrapment syndrome (PAES) is a rare vascular disorder characterized by the compression of the popliteal artery behind the knee, primarily affecting physically active individuals. This is a case of a 36-year-old man who presented with a 1-week history of sudden-onset left leg pain. Diagnostic evaluation, including physical examination, color duplex ultrasonography, computed tomography, and magnetic resonance imaging, revealed a popliteal artery pseudoaneurysm caused by type 5 PAES. The patient underwent surgical exploration to release the entrapment, followed by an interposition graft with the ipsilateral great saphenous vein...

BACKGROUND: The aim of the present study was to assess early and long-term results of open surgical interventions for popliteal artery aneurysms (PAAs) with the use of heparin-bonded expanded polytetrafluorethylene (HePTFE) in a single center, retrospective, non-comparative cohort study. METHODS: A retrospective analysis of a prospectively maintained dataset, including 207 open interventions for PAAs between 2002 and 2022, was performed and 170 procedures carried on with the use of a HePTFE graft were found...

OBJECTIVE: Single segment, greater saphenous vein (GSV) conduit is considered the optimal bypass conduit among patients undergoing bypass surgery for peripheral artery disease (PAD). While this data has been extrapolated to patients undergoing bypass for popliteal artery aneurysms (PAA), the pathophysiology of PAA is inherently different when compared to PAD, and the impact of conduit type on long-term outcomes after open repair of PAA remains unclear. METHODS: A multicenter database of five regional hospitals was retrospectively reviewed for all patients with PAA undergoing open surgical repair...

BACKGROUND: Popliteal artery aneurysms (PAAs) need urgent treatment in case of acute thrombosis, distal embolization, or rupture. Few data are available in the literature about the treatment results in these scenarios. The aim of the present study was to evaluate an 11-year multicenter experience in the urgent treatment of PAAs. METHODS: All symptomatic PAAs surgically treated in two vascular centers between 2010 and 2021 were retrospectively analyzed. In the postoperative period periodical clinical and Duplex-Ultrasound evaluation were performed...

PURPOSE: To evaluate endovascular popliteal artery aneurysm repair using a an "off-label" abdominal endograft limb-module with nitinol-ring structure. MATERIALS AND METHODS: Retrospective observational study of 14 popliteal artery aneurysms in 12 male patients (mean age 76 years and median ASA grade 3) treated electively using the Anaconda™ endograft limb (Terumo Aortic) at a single teaching hospital. Eight limbs were treated percutaneously and 6 limbs required surgical arterial exposure...

INTRODUCTION: The development of intrastent thrombosis is one of the mechanisms related to medium- to long-term failure of endovascular treatment of popliteal artery aneurysm. The present study aims to investigate possible links between the development of endoluminal mural thrombotic apposition in the stented zone (EMTS) with both geometrical features of stent-graft(s) and time of follow-up. METHODS: Patients with popliteal artery aneurysm who underwent endovascular treatment were recruited during the follow-up period...

Mycotic aneurysms are a well-recognised complication of non-typhoidal Salmonella bacteraemia; the risk is increased in patients with atherosclerotic disease. The infrarenal abdominal aorta is the most common site of infection; lower extremity aneurysms are uncommon.1 Here we present the case of a patient with cardiovascular disease and recurrent non-typhoidal Salmonella bacteraemia, who developed a left-sided popliteal artery mycotic aneurysm with secondary popliteal vein thrombosis. The aneurysm was diagnosed upon rupture, and managed with surgical excision and bypass graft...

INTRODUCTION: Prior studies have demonstrated acceptable midterm outcomes with prosthetic conduits for above-knee bypass for occlusive disease in patients with inadequate segment great saphenous vein (GSV). In this study we aimed to investigate whether this holds true for open repair of popliteal artery aneurysms (PAA). METHODS: We queried the Vascular Quality Initiative data for patients who underwent open PAA repair (OPAR). We divided the cohort into three groups based on the conduit used: GSV, other autologous veins, or prosthetic graft...

Background and Objectives : Persistent sciatic artery (PSA) is a rare congenital vascular anomaly that is often asymptomatic, but can be associated with aneurysm formation and potential complications, such as thromboembolism or aneurysm rupture in some cases. We present a case of a 75-year-old woman with a symptomatic thrombus-containing aneurysm of the left PSA. Materials and Methods : The treatment of the PSA aneurysm involved a successful hybrid approach, which included open surgical bypass and endovascular embolization...

Middle-aged adults can start to be affected by some arterial diseases (ADs), such as abdominal aortic or popliteal artery aneurysms, lower extremity arterial disease, internal carotid, or renal artery or subclavian artery stenosis. These vasculopathies are often asymptomatic or paucisymptomatic before manifesting themselves with dramatic complications. Therefore, early detection of ADs is fundamental to reduce the risk of major adverse cardiovascular and limb events. Furthermore, ADs carry a high correlation with silent coronary artery disease (CAD)...

Popliteal artery aneurysm (PAA) is the most frequent peripheral aneurysm, primarily seen in male smokers with a prevalence below 1%. This exploratory study aims to shed light on cellular mechanisms involved in PAA progression. Sixteen human PAA and eight non-aneurysmatic popliteal artery samples, partially from the same patients, were analyzed by immunohistochemistry, fluorescence imaging, Affymetrix mRNA expression profiling, qPCR and OLink proteomics, and compared to atherosclerotic ( n = 6) and abdominal aortic aneurysm (AAA) tissue ( n = 19)...

Popliteal pseudoaneurysms are a rare vascular pathology, usually caused by trauma or iatrogenic interventions. Idiopathic cases are exceptionally uncommon. This case report aims to describe the diagnosis and successful endovascular treatment of an idiopathic pseudoaneurysm of the popliteal artery in a 90-year-old bedridden female patient presented with acute pain and swelling in the left knee at the emergency department. The patient underwent successful endovascular treatment with a covered stent and thrombin injection, leading to complete exclusion of the pseudoaneurysm...

INTRODUCTION: In managing arterial rupture, stent-graft implantation may cause limb ischemia by crossing a major branch for hemostasis. The ViaHole technique could circumvent a major branch occlusion. MATERIALS AND METHODS: The process involved advancing retrograde devices into an occluded major branch by the stent-graft implantation to reach the outer surface of the stent-graft, puncturing the stent-graft with a 20-gauge needle to touch the retrograde device, manipulating the guidewire through the needle hole and externalizing it, advancing the microcatheter into the proximal lumen, catching the microcatheter using an antegrade 4-Fr catheter, inserting an antegrade guidewire into the retrograde microcatheter to cross the stent-graft hole, dilating the lesion and stent-graft hole using a 3...

INTRODUCTION: Venous aneurysms are rare, so their natural history is not fully understood. Indications for treatment are often determined by the location and size of the aneurysm; however, considering the scarcity of data, there are no specific recommendations. Surgery is the mainstay for venous aneurysm treatment, but some authors reported successful endovascular treatment. We intend to describe our experience with this type of rare disorder. METHODS: A post hoc observational study of a prospectively maintained registry including consecutive patients admitted with the diagnosis of a venous aneurysm at different locations between January 2007 and September 2021...
