Abstracts must be submitted via SVU’s online abstract platform. Instructions on how to submit are included at the top of this page. Once submitted the system will send you a confirmation email noting that you have completed the submission process. Any abstract not submitted online will not be considered.

A presenter is required to be an SVU member or be sponsored by an SVU member. Exception: Student Awards (Student Oral Presentation Awards and Student Poster Presentation Award) and the Alex Chao, MD, Young Investigator Award does not need to be submitted or sponsored by a SVU Member.

1. If the abstract is accepted, one of the authors must present it at the SVU Annual Conference.
2. If the abstract is accepted for an oral clinical or oral scientific presentation at the SVU Annual Conference, the author must upload a manuscript to Sage Track via https://mc.manuscriptcentral.com/jvu by a pre-determined date. You are able to edit the manuscript before it is finalized and selected for publishing. Details to be provided in your acceptance letter. Do not send manuscripts to JVU editors. Manuscript review is an essential part of the awards process; missing this deadline will make you ineligible for any SVU awards considered and your may not be allowed to present.
3. Scientific, oral clinical, oral case studies and poster presentations (scientific, clinical and case studies) will be considered for awards at the SVU Annual Conference. Manuscripts are only required for the oral scientific and oral clinical presentations.
4. Privacy of patients – Revealing the identity of patients in a public forum is against the law under HIPAA federal regulations. Please remove all patient’s identification information (in slides, posters and any other part of the presentation, as well as the abstract). Do not include the name of an institution in the abstract text.
5. Abstracts that are primarily commercial in nature will not be accepted.
6. ABSTRACTS SUMISSIONS NOT ADHERING TO PUBLISHED SVU ABSTRACT FORMAT GUIDELINES WILL BE DISQUALIFIED AND RETURED TO THE SUBMITTING AUTHORS.

Abstract Evaluation
Abstracts are blinded before they are sent to the SVU Abstracts Subcommittee for scoring. Selection is based on the following criteria:

Originality and Content:

• Adequately describes new technique (or new application of old technique)

Language:

• Proper grammar, spelling and is well written Abstract Structure and Overall Quality:
• Abstract reflects title
• Introduction/background provides relevant information
• Methods clearly stated
• Results presented clearly, logically and address the purpose
• Conclusions supported by the results

Large External Carotid Artery Pseudoaneurysm: Rare Complication Following Microvascular Free Flap Reconstruction

Submission Type: Poster Case Study

Author Category

Introduction/Patient Description
Pseudoaneurysm (PSA) associated with microvascular free flap reconstruction in the neck is rare, with only two reported cases in the literature. We report a case of an external carotid branch artery PSA in a patient who had previously undergone a total laryngectomy, neck dissection and microvascular free flap reconstruction of the
pharynx. The use of color flow duplex ultrasound (CDU) in the diagnosis and treatment of this patient will be discussed.

Methods
This patient was referred to the vascular lab after identification of a large. intraoral PSA by computed tomography and an unsuccessful attempt to cannulate the feeding artery by lnterventional radiology. At the request of the vascular surgeon. CDU was utilized to further delineate the size. depth and feeding artery of this PSA.

Results
CDU revealed a prominent to/fro flow waveform in the first branch arising from the external carotid artery. Color flow and spectral Doppler were present in the PSA. The distance from the surface of the skin to the flow active core of the PSA was 3.1 cm. Due to the complexity of the PSA, cannulation of the feeding artery could not be achieved for coil embolization. With the information obtained on CDU, treatment was achieved by a
transcutaneous thrombin injection (Tl) under fluoroscopic and ultrasound guidance. Completion angiography verified success of the Tl and demonstrated internal and external carotid patency.

Conclusion/Discussion
CDU was valuable not only in the diagnosis of this unusual PSA. but in the successful treatment and follow-up of this patient. We believe our patient to be the first documented case of transcutaneous Tl for the treatment of PSA following microvascular free flap reconstruction.

Effect of aortic stenosis on the common carotid artery Doppler waveforms

Submission Type: Scientific Oral

Author Category

Introduction
The common carotid artery (CCA) Doppler waveform is subjectively evaluated as blunted In patients with severe aortic stenosis (AS). It is possible that quantitative measurements of the CCA waveform might offer additional diagnostic value.

Methods
We performed a retrospective study of 145 consecutive patients with carotid Doppler examinations and echocardiography within a one-day Interval of each other. AS was classified as mlld, moderate, or severe based on estimated valve area or mean trans valve gradient. The associations between degree of AS and the following variables were evaluated by ANOVA'. peak-systolic velocity (PSV), end-diastolic velocity (EDV), the time to peak velocity (TTPV = time from EDV to PSV), and the acceleration time (AT= duration of constant increase in systolic velocity before the compliance peak). Receiver operating characteristic (ROC) curves were generated and areas under the curves (AUCs) estimated.

Results
There were 118 patients without AS, 5 with mild, 10 with moderate and 12 with severe AS (mean age 67.7 years, 64% men). AT (p < 0.0001) and TIPV (p < 0.0001) were consistently increased with the degree of aortic stenosis. Both variables and EDV were associated with the presence of AS. Presence of AS was strongly predicted by AT (AUC = 0.76; p< 0.0001) and TIPV ( AUC = 0.84; p< 0.0001) but mildly by EDV (AUC = 0.59; p = 0.049).

Conclusion/Discussion
The AT and the TIPV are more strongly associated with the presence of aortic stenosis than PSV or EDV.
