Medical Management of Peripheral Arterial Disease.

Peripheral arterial disease is a condition associated with high rates of cardiovascular morbidity and mortality, increased risk of adverse limb events, including development of critical limb ischemia and amputation, and also with decreased quality of life. This manuscript provides an overview of the medical management of patients with peripheral arterial disease. We discuss contemporary therapies that decrease major adverse cardiovascular and limb events among patients with peripheral arterial disease, and also therapies that improve the patient's ability to walk and quality of life in general.

Objective: To qualitatively and quantitatively evaluate the 2-year magnetic resonance imaging (MRI) outcome after MPFL reconstruction at the knee and to assess MRI-based risk factors that predispose for inferior clinical and imaging outcomes.

Materials And Methods: A total of 31 patients with MPFL reconstruction were included (22 ± 6 years, 10 female). MRI was performed preoperatively in 21/31 patients.

Methods: A nested case control study of 120 patients (42 ± 17 years, 53% women, mean 2.

Incidence of Stent Thrombosis after Endovascular Treatment of Iliofemoral or Caval Veins in Patients with the Postthrombotic Syndrome.

Background:  Patients with postthrombotic syndrome (PTS) treated with stents are at risk of stent thrombosis (ST). The incidence of ST in the presence and absence of anticoagulation therapy (AT) is unknown. Risk factors are not well understood.

Cardiac biomarkers but not measures of vascular atherosclerosis predict mortality in patients with peripheral artery disease.

Background: Peripheral artery disease (PAD) becomes more prevalent with advancing age and is associated with elevated risk of cardiovascular events and shortened life expectancy. We investigated the prognostic performance of cardiac and vascular biomarkers in a cohort of PAD patients.

Methods: A total of 95 PAD patients were enrolled (mean age 68 years, range 47 to 86 years, 73 males).

Cessation of anticoagulation therapy following endovascular thrombus removal and stent placement for acute iliofemoral deep vein thrombosis.

The optimal duration of anticoagulation therapy (AT) following catheter-based therapy of acute iliofemoral deep vein thrombosis (IFDVT) with stent placement is unknown. Theoretically, resolving the underlying obstructive iliac vein lesion by a stent may eliminate the main trigger for recurrence, the post-thrombotic syndrome (PTS), and the need for extended-duration AT. From 113 patients with acute IFDVT who underwent endovascular thrombus removal and stent placement, we compared patency rates and clinical outcomes between 58 patients on limited-duration AT (3-12 month) and 55 patients on extended-duration AT (> 12 months).

Cartilage repair surgery prevents progression of knee degeneration.

Purpose: To investigate, whether cartilage repair surgery for focal osteochondral defects at the knee results in less degenerative changes over 6 years in a MR imaging follow-up than morphologically initially identical defects in non-operated control subjects from the osteoarthritis initiative (OAI).

Methods: A total of 32 individuals received baseline and follow-up MRI. In n = 16 patients with cartilage repair [osteochondral autograft transfer system (OATS), n = 12; spongiosa-augmented matrix-associated autologous chondrocyte implantation (MACI), n = 4] MRI was performed preoperatively and after 5.

Rivaroxaban or vitamin-K antagonists following early endovascular thrombus removal and stent placement for acute iliofemoral deep vein thrombosis.

Background: The optimal anticoagulant following catheter-based therapy of acute iliofemoral deep vein thrombosis (IFDVT) is unknown.

Methods: From the Swiss Venous Stent registry, an ongoing prospective cohort study, we performed a subgroup analysis of patients with acute IFDVT who underwent catheter-based early thrombus removal followed by nitinol stent placement. Duplex ultrasound and Villalta scores were used to determine patency rates and incidence of the post-thrombotic syndrome (PTS) in patients treated with either rivaroxaban (n = 73) or a vitamin K-antagonist (VKA; n = 38) for a minimum duration of 3 months.

Reliable semiquantitative whole-joint MRI score for the shoulder joint: The shoulder osteoarthritis severity (SOAS) score.

Background: Shoulder osteoarthritis causes severe pain and functional disability. Preventive surgical procedures aiming to halt the progression of degenerative changes are increasingly applied. However, no MRI-based score exists that may be applied for scoring of osteoarthritic changes and their progression.

Rivaroxaban versus fondaparinux for thromboprophylaxis after endovenous laser ablation.

Objective: Endovenous heat-induced thrombosis (EHIT) and deep venous thrombosis (DVT) are well-known complications after superficial endovenous thermoablation. We investigated the efficacy of rivaroxaban in preventing EHIT and DVT after endovenous laser ablation (EVLA).

Methods: We retrospectively analyzed a consecutive series of patients presenting with truncal varicosis class C to C undergoing EVLA.

Sensitivities of in vivo markers of arterial organ damage in patients with peripheral atherosclerosis.

Background: Biomarkers of vascular diseases such as ankle-brachial index (ABI), peripheral pulse pressure (pPP), central pulse pressure (cPP), and pulse wave velocity (PWV) allow assessment of arterial organ damage (AOD). However, the utility of markers other than ABI in patients with peripheral arterial disease (PAD), which are also associated with a significant increase of cardiovascular events, remains unclear.

Patients And Methods: Asymptomatic (n = 21) and symptomatic patients (n = 46) with a positive sonography for PAD or history of lower limb revascularization were included.

We report a case of a 56-year-old male patient with a life-threatening left common femoral artery bleeding due to tumor erosion. The patient had a history of advanced high-grade pleomorphic leiomyosarcoma of the left groin with pulmonary metastasis. Clinical examination revealed a massive tumor bulking at the left groin with necrosis and phleb- and lymphedema.
