Percutaneous transluminal angioplasty and stenting is becoming increasingly the first line treatment for patients with both claudication and critical limb ischaemia instead of surgery, with the aim of returning the patient's quality of life in the former and preventing amputation. Drug eluting technologies have seen a large surge in popularity in recent years, and significant patient benefits have been seen with the use of drug eluting stents and balloons over the use of plain balloon angioplasty. Unfortunately in many patients with arterial disease there is significant vessel wall calcification - this can theoretically be a barrier to drug delivery, and can also be a contributing factor to flow limiting dissection and the subsequent need for bail out stenting...

Background: Popliteal artery entrapment syndrome (PAES) is a very rare pathology that can cause lower extremity ischemia in healthy young people. Anomalous anatomic relationships between the popliteal artery (PA) and the surrounding musculo-tendinous structures cause PAES. We present 31 patients with PAES in 35 limbs that were treated surgically in our clinic within a 12-year period. Patients and Methods: From 2001 to 2015, 31 patients (mean age: 32 ± 7.4 years) underwent surgery for PAES...

BACKGROUND: This systematic review examines the benefit and harm of adding epinephrine to local anesthetics for epidural, intrathecal, or locoregional anesthesia. METHODS: We searched electronic databases to October 2017 for randomized trials comparing any local anesthetic regimen combined with epinephrine, with the same local anesthetic regimen without epinephrine, reporting on duration of analgesia, time to 2 segments regression, or any adverse effects. Trial quality was assessed using the Cochrane risk of bias tool and a random-effects model was used...

We describe a case of an infected popliteal artery stent with septic emboli presenting 6 years after peripheral vascular intervention for intermittent claudication. Management included resection of the stent and popliteal artery and revascularization by femoral-popliteal bypass with autogenous vein. This case demonstrates that peripheral stent infections can develop years after intervention. We performed an English language PUBMED literature review of arterial peripheral vascular stent infections on using the search term, "Non-coronary stent or stent graft infection from 1966 to present...

T cell-mediated responses have been implicated in the development of fibrosis, impaired lymphangiogenesis, and lymphatic dysfunction in secondary lymphedema. Here we show that CD4+ T cells are necessary for lymphedema pathogenesis by utilizing adoptive transfer techniques in CD4 knockout mice that have undergone tail skin and lymphatic excision or popliteal lymph node dissection. We also demonstrate that T cell activation following lymphatic injury occurs in regional skin-draining lymph nodes after interaction with antigen-presenting cells such as dendritic cells...

PURPOSE: Debulking strategies prior to drug-coated balloon (DCB) angioplasty were suggested to improve clinical results in femoro-popliteal lesions. Currently, there are no data regarding plaque modification with a scoring balloon with subsequent DCB-angioplasty. Recently published 6-month results of the DCB-Trak registry in patients treated with scoring-balloon angioplasty and DCB-angioplasty were promising without any safety concerns. Herein, we report the 12-month follow-up data. METHODS: In a single center registry, 29 consecutive patients with 32 femoro-popliteal lesions were treated with a scoring-balloon (VascuTrak®) and a DCB subsequently...

Objective: To analyze the amount of weight-bearing during tilt table increments, with a review of neutral and unilateral knee flexion postures. Methods: There were 17 healthy participants enrolled in this study. The subjects were tilted from 10° to 90°, and their body weight was measured at each 10° increment. In the first test, both plantar pressures, with the subjects in neutral posture, were recorded. During the second and third tests, the angle of inclination was thus recorded and increased, with the subjects in unilateral knee flexion posture; flexion was maintained at 25° by attaching a cylindrical support to the tilt table at the level of the popliteal fossa...

Intralymphatic histiocytosis is a rare disorder associated with a variety of inflammatory conditions. We report the case of an 89-year-old woman with a history of a right knee replacement and a ruptured popliteal cyst who developed an erythematous indurated plaque over the surgical scar. Histopathology revealed fibrosis, chronic inflammation, and histiocytes within the lymphatics consistent with intralymphatic histiocytosis. The plaque flattened following intralesional injection of triamcinolone acetonide 10 mg/cc×1...

Degenerative femoral artery aneurysms are uncommon and often associated with aneurysm in other distributions. We report a case of a 68-year-old man with multianeurysmal disease involving the aorta, iliac, femoral, and popliteal arteries managed interdisciplinary by stent-graft placement and open surgical repair. Genetic testing revealed a variant in the FBN2 gene encoding fibrillin-2, an important component of microfibrils. We detail arterial reconstruction of the femoral artery and discuss incidence, diagnosis, and therapy of femoral artery aneurysms...

An 8-year-old, intact female, mixed-breed dog presented to the Oklahoma State University Boren Veterinary Medical Teaching Hospital for evaluation of progressive lameness and joint effusion of multiple joints. Physical examination revealed joint effusion of the elbow, hock, and stifle joints bilaterally, enlarged left axillary and right popliteal lymph nodes, a subcutaneous mass over the left elbow, and a subcutaneous mass involving the left second and third mammary glands. Cytologic examination of the mammary mass, enlarged lymph nodes, and joint fluid from most affected joints revealed a monomorphic population of loosely cohesive neoplastic epithelial cells...

OBJECTIVES: This study was designed to evaluate outcomes of adventitial dexamethasone delivery adjunctive to standard endovascular revascularization in femoropopliteal peripheral artery disease. BACKGROUND: Drug-coated balloons and drug-eluting stents improve patency of endovascular interventions with passive diffusion of antiproliferative drugs. Adventitial dexamethasone delivery targets the initial triggers of the inflammatory reaction to injury, thus potentially providing a potent antirestenotic strategy...

Since lymphedema rarely develops in the mouse hindlimb, the underlying mechanisms remain unclear. We herein investigated the resolution of chronic hindlimb lymphedema in mice using a Near-Infrared Fluorescence (NIRF) imaging system. Nineteen 7-28-week-old BALB/c male and female mice were injected with two dyes for lymphography and dissection. Lymphadenectomy was performed on six male mice to completely obstruct lymph flow in the hindlimb. Edematous changes in both hindlimbs were compared until 60 days after surgery...

BACKGROUND: Adductor canal block (ACB) is a peripheral nerve blockade technique that provides good pain control in patients undergoing total knee arthroplasty which however does not relieve posterior knee pain. The recent technique of an ultrasound-guided local anesthetic infiltration of the interspace between popliteal artery and the capsule of posterior knee (IPACK) has shown promising results in providing significant posterior knee analgesia without affecting the motor nerves. MATERIALS AND METHODS: A prospective study was conducted from September 2016 to March 2017 in a total of 120 patients undergoing unilateral total knee arthroplasty...
