Venous thromboembolism, commonly presented as pulmonary embolism and deep-vein thrombosis, is a paramount and potentially fatal condition with variable clinical presentation. Diagnosis is key to providing appropriate treatment in a safe and timely fashion. Clinical judgment and assessment using clinical scoring systems should guide diagnostic testing, including laboratory and imaging modalities, for optimal results and to avoid unnecessary testing.

However, mortality risk in this population has been mixed. As such, we sought to evaluate all-cause mortality by race among individuals with PAD.

Methods: We performed a retrospective review of medical charts for patients diagnosed with SRAD at a single, tertiary care center.
Few studies have documented relationships between endovascular therapy, duplex ultrasonography (DUS), post-thrombotic syndrome (PTS), and quality of life (QOL). The Acute Venous Thrombosis: Thrombus Removal with Adjunctive Catheter-Directed Thrombolysis (ATTRACT) trial randomized 692 patients with acute proximal deep vein thrombosis (DVT) to receive anticoagulation or anticoagulation plus pharmacomechanical catheter-directed thrombolysis (PCDT). Compression DUS was obtained at baseline, 1 month and 12 months.
View Article and Find Full Text PDFAmphetamine and its related derivatives and analogues (ADRA) are highly addictive central nervous system stimulants that are used commonly in the treatment of attention-deficit/hyperactivity disorder and narcolepsy. These medications are associated with many side effects but reports of peripheral arterial manifestations associated with ADRA usage are scarce. We retrospectively reviewed the records of 16 patients (median age 37 years (IQR 31-47), 13 females) referred to a single tertiary referral service while receiving ADRA.

Not much is known about the natural history and appropriate treatment. We retrospectively queried a prospectively collected institutional radiology database for all patients diagnosed with SICMAD from 1990 to 2017.

Methods: We reviewed all patients diagnosed with radial artery PSA resulting from arterial line placement or radial artery access for cardiac procedures from 2010 to 2015.
Results: We identified 11 cases: 5 caused by arterial lines and 6 by cardiac procedures.
Above knee and below knee patency for synthetic endografts are vastly different. Long-term data is encouragingly similar to synthetic bypass grafting. Optimize use of synthetic endografts in above knee femoropopliteal segments in non-critical limb ischemia patients.

Methods: In this single-center, retrospective, cohort study, patient records from January 2002 to December 2013 were queried for terminology consistent with PVA.
Venous thromboembolism remains one of the most common conditions. Pulmonary embolism carries a mortality rate of over 15 % in the first 3 months after diagnosis. Venous thromboembolism is the fourth leading cause of death in the Western world, and the third leading cause of cardiovascular death trailing myocardial infarction and stroke.

Background: Transcatheter PFO closure is commonly performed for several indications, including cryptogenic stroke, despite conflicting data regarding the efficacy of this intervention.
Methods: We report the outcomes of 800 consecutive patients (52% male, 50 ± 14 years of age) who underwent PFO closure at our institution after multidisciplinary evaluation over a 16-year period.

Background: Supra-normal ankle brachial index (ABI) (>1.40), poses diagnostic challenges to determine the presence, location, and severity of peripheral artery disease (PAD). The anatomic distribution of PAD in patients with elevated ABI has not been previously described.

Upper extremity deep venous thrombosis (UEDVT) accounts for between 4% and 10% of all deep venous thromboses, and may be due to primary or secondary causes. The incidence of UEDVT is increasing, partly due to the exponential growth in the use of central venous catheters and the increasing placement of permanent cardiac pacemaker or defibrillator devices. UEDVT not only compromises future vascular access but results in significant morbidity and mortality, with symptomatic pulmonary embolus occurring in approximately 12%, post-thrombotic syndrome in 13%, and mortality ranging from 15-50%.
View Article and Find Full Text PDFBackground: Duplex ultrasonography criteria for assessing the severity of carotid artery (CA) in-stent restenosis are not well established.
Methods And Results: We analyzed 39 patients (40 CAs) who underwent CA stenting with baseline and 6-month follow-up carotid duplex ultrasonography and intravascular ultrasound. Intravascular ultrasound measurements included minimum luminal diameter, percent diameter, and lumen area stenosis.
Purpose: To present the safety and short-term outcomes of using controlled blunt microdissection catheter-assisted revascularization of symptomatic chronic total occlusions of the lower extremity.
Materials And Methods: A retrospective study was performed on 61 patients (46 men) with a mean age of 72.3 years +/- 9.
The objective of this study was to analyze the use of sirolimus-eluting stent (SES) placement for the treatment of renal artery in-stent restenosis (RA-ISR). The optimal treatment of RA-ISR has not been fully elucidated to date. We retrospectively analyzed consecutive patients from our institution who underwent treatment of RA-ISR with a SES from May 2004 to June 2006.

Materials And Methods: This was a retrospective study of all patients with RAS and CRI treated concomitantly with a GuardWire EPD and renal artery stents from December 2002 through June 2006. Renal function was determined by calculating the estimated glomerular filtration rate (eGFR) according to the Modification of Diet in Renal Disease formula, and subjects were divided into Kidney Disease Outcomes and Quality Initiative (K-DOQI) classes based on baseline eGFR.
Background And Purpose: We aimed to investigate the incidence of May-Thurner syndrome in patients with cryptogenic stroke with patent foramen ovale.
Methods: This was a retrospective study. All consecutive patients with cryptogenic stroke having undergone patent foramen ovale closure from January 1, 2002, to December 31, 2007, at our institute were included in this study.
We report a case of severe deep venous thrombosis (DVT) treated with multimodality therapy that was complicated by sepsis due to thrombus likely infected by Salmonella virchow. We review the current therapeutic options in the therapy of severe DVT and cardiovascular pathology associated with non-typhoid Salmonella.
