Validating the Clinical Value of Temporal Artery Biopsy.

BACKGROUND: Giant cell arteritis (GCA) is a potentially devastating disease that may require treatment with high-dose steroids. Traditionally, diagnosis requires patients to meet at least 3 of 5 clinical criteria, one of which is a positive temporal artery biopsy (TAB). Vascular surgeons are often asked to perform TAB though it is not necessarily required for diagnosis or management. This study aimed to determine if TAB results altered management of patients with a concern for GCA by changing steroid use postoperatively in our health care system. METHODS: A retrospective review at a single-center tertiary care hospital was performed between 2007 and 2018. The inclusion criteria were patients greater than 18 years old with complete steroid treatment records who underwent a temporal artery biopsy due to concern for GCA. Steroid use and duration of treatment both pre- and post-operative were collected and analyzed. RESULTS: Eighty-three of 117 cases reviewed met inclusion criteria. Ninety-one percent (76) of patients had a negative biopsy. Twenty-nine percent (23) of negative biopsies met criteria for GCA prior to biopsy. Of those with a negative biopsy, steroids were continued in 68% (52) of patients after 30 days, 49% (37) after 90 days and 45% (34) after 180 days. Steroids were never started in 11% (6). One patient with a positive biopsy was discontinued on steroids due to intolerance. There was no statistically significant difference in duration of steroids between those with a positive and negative biopsy (average 610 and 787 days respectively; P = 0.682). Average follow up was 33 months. DISCUSSION: The duration of steroid use for patients with concern for GCA was not found to be altered by the performance of a TAB at our institution. Given the extremely low yield and absence of impact on steroid duration, TAB is not a useful diagnostic test at our institution. Similar reviews are recommended to determine the utility of TAB at other institutions that may differ in patient population or prescribing practices.

Spontaneous brachial artery pseudoaneurysm secondary to vasculitis.

BACKGROUND: Avoiding operative intervention during the active phase of vasculitis is a central tenant of management of this pathology. For unusual presentations of vascular disease, the early diagnosis of vasculitis is imperative to guide treatment. METHODS: We present the case of a 68-year-old female who presented with a spontaneous brachial artery pseudoaneurysm and was found to have granulomatosis with polyangiitis. RESULTS AND CONCLUSION: The management of arterial complications of vasculitis are particularly difficult in the active phase of disease. Our patient had successful resolution of her pseudoaneurysm with ultrasound compression, avoiding open or endovascular intervention during the active phase of disease.

Recurrent upper extremity acute limb ischemia secondary to retained axillary polytetrafluoroethylene cuff causing axillary stump syndrome.

Acute limb ischemia of the upper extremity is less frequently encountered than in the lower extremity. The etiology is typically cardioembolic. Axillary-femoral stump syndrome is a rare complication associated with an occluded axillary-femoral bypass graft. We present the case of recurrent acute limb ischemia of the upper extremity whose embolic source was a retained cuff of a previously explanted axillary-profunda bypass graft. The patient failed anticoagulation after an initial embolectomy and after a recurrent embolism from the retained cuff, ultimately required cuff exclusion with a covered stent.

Poly-Specialty Application Practices of Medical Students Applying to Integrated Vascular Surgery Residency.

BACKGROUND: It is not uncommon for medical students seeking surgical residencies to apply to and rank two or more surgical specialties. Level of interest in a specialty is consistently cited as one of the most important factors for program directors when evaluating applicants for 0 + 5 integrated vascular surgery (IVS) programs. The purpose of this study was to examine trends in poly-specialty application submission to IVS and poly-specialty ranking of IVS to determine the percentage of applicants to IVS residencies with vascular surgery as their true preference. METHODS: Electronic Residency Application Service (ERAS) statistics for noninternational medical graduates from 2011 to 2017 were mined for trends in poly-specialty applications between IVS and other surgical disciplines. The poly-specialty application percentage, range, and standard deviation were determined. The National Resident Match Program (NRMP) results and data from 2011 to 2018 were also used to identify those U.S. seniors who ranked IVS programs as their preferred choice, defined as ranking vascular as the only choice or the first-choice specialty. This was compared with those who ranked a specialty other than vascular surgery first but had vascular surgery listed on their rank list. These data were also collected for applicants to orthopedic surgery, neurosurgery, otolaryngology, obstetrics and gynecology, integrated cardiothoracic surgery, and integrated plastic surgery. RESULTS: Between 2011 and 2017, applicants who submitted ERAS applications to IVS most often poly-specialty applied to IVS and general surgery (87%) followed by IVS and the following: preliminary surgery (71%), plastic surgery (22%), orthopedic surgery (19%), neurosurgery (17%), otolaryngology (16%), obstetrics and gynecology (12%), and urology (3%). The percentage of the applicant pool submitting rank lists with multiple specialties fell over the study period from 94% in 2011 to 67% in 2018. Between 2011 and 2018, an average of 14% of IVS applicants (n = 463), who submitted rank lists to the NRMP, ranked a specialty other than vascular as their true preference (range 7-23 SD 5). Only integrated cardiothoracic surgery had a higher percentage of applicants listing a different specialty as their true preference at 25% (range 18-36 SD 7). Nearly all (97-99%) applicants to orthopedic surgery, neurosurgery, otolaryngology, obstetrics and gynecology, and plastic surgery applied to that specialty as their true preference. CONCLUSIONS: IVS residency applicants were most likely to apply for poly-specialty via the ERAS to general surgery and IVS. Compared to the other surgical specialties, those who submitted rank lists to the NRMP listing integrated cardiothoracic and IVS had the highest likelihood of ranking another specialty higher. Care must be taken when evaluating applications to IVS residencies to determine the applicant's level of interest in vascular surgery as a career.

Herpes wound infection after femoral endarterectomy.

Wound infection after common femoral endarterectomy is a well-documented phenomenon leading to significant morbidity, especially in the setting of a prosthetic graft. A push has recently been made in the literature for salvage of the prosthetic graft using debridement, antibiotics, and vacuum-assisted closure therapy. Herein we present the case of wound infection after common femoral endarterectomy with bovine patch angioplasty initially presumed to be of bacterial origin that failed to respond to vacuum-assisted closure therapy until the viral nature of the pathogen was discovered. The patient will continue lifelong valacyclovir for suppressive therapy.
