Research Summary
Dr Chaar’s research focuses on clinical outcomes using large national database analysis such as the ACS-NSQIP , the VQI and the NIS. He also leads multiple clinical trials at Yale New Haven Hospital. He studies and publishes on various aspects of vascular disease including peripheral artery disease, varicose veins, venous thromboembolism, and aortic aneurysms. The work of his research team is regularly presented in several regional and national vascular societies scientific meetings including the New England Society of Vascular Surgery (NESVS), the Eastern Vascular Society (EVS), the Vascular and Endovascular Surgery Society (VESS), the American Venous Forum (AVF), the Society of Clinical Vascular Surgery (SCVS), and the Society of Vascular Surgery (SVS).
Dr. Chaar has mentored several trainees in conducting research projects and helped them prepare and present their work at national meetings. He formulates a research project in vascular disease based on the student's interests and the knowledge gap in the literature. His philosophy in research relies on engaging the trainees and making sure they are genuinely interested in the questions they are trying to answer. "That is the key to success", states Dr. Chaar. As such the trainees can chose between a retrospective study based on clinical work done at Yale, a database analysis based on national databases or even can design a small prospective study to examine specific treatments or outcomes of interest. Last, there are always opportunities to write and publish case reports of challenging patients treated in novel modalities.
Extensive Research Description
Research Projects for Students and Residents
Project 1:
Title: The significance of reinterventions in the treatment of peripheral artery disease (PAD)
Description: Patients treated with open or endovascular revascularization of the lower extremities undergo frequently repeated intervention to sustain patency and to provide limb salvage in patients with critical limb ischemia. This project studies the impact and costs of reinterventions on patient outcomes.
Project 2:
Title: Management of vascular disease in the very old
Description: As the population ages, vascular surgeons increasingly face complex patients in their 80s and 90s requiring treatment. This project aims to study the trends in treatment of vascular disease in the elderly, as well as the outcomes and focus on the impact on quality of life.
Project 3:
Title: Effect of loco/regional anesthesia on outcomes of vascular surgery
Description: Advances in anesthesia technique as well as the introduction of longer acting local anesthetics allows vascular surgery specially hybrid procedures to be effectively performed on patients while minimizing pain in the perioperative period. This project studies the impact of these anesthesia techniques on patient outcome and satisfaction.
Project 4:
Title: Universal Algorithm for venous disease
Description: Our understanding of venous disease and its treatment has evolved and there are several structural anomalies that can be surgically treated that can improve patient symptoms. However, there is no recommended and well defined protocol for the approach to the patient. This project studies the effect of the Yale Vascular Surgery protocol on the evaluation and outcomes of patients with venous disease affecting the lower extremities.
Project 5:
Title: Iliofemoral DVT and post phlebetic syndrome in the DOAC era
Description: This study aims to study the risk of postphlebetic syndrome after iliofemoral DVT in patients on DOAC compared to coumadin
Project 6:
Title: Inferior vena cava position and its relation to complications
Description: IVC filters are still commonly inserted and carry long-term risks of complications. The ideal position for IVC filters is still controversial. This study examines the position of the filters in the cava and correlates it with possible complications.
Project 7:
Title: Predictors of success after stenting iliac vein compression
Description: Iliac vein compression remains a challenging condition to diagnose as there is a good percentage of asymptomatic patients that are found incidentally to have compression of the iliac veins. This study examines the predictors of success after iliac vein stenting in order to enhance patient selection and optimize outcomes.
Project 8:
Title: Smoking cessation in vascular patients
Description: Smoking is very prevalent in patients with vascular disease. Patients get advised about smoking cessation all the time. This study looks at different means to enhance cessation in vascular patients in the inpatient as well as the outpattient settings.
