Surveillance duplex ultrasound prompted interventions after carotid endarterectomy.

OBJECTIVE: Current societal guidelines recommend duplex ultrasound (DUS) surveillance beyond 30 days after carotid endarterectomy (CEA) for patients with risk factors for restenosis or who underwent primary closure. However, the appropriate duration of this surveillance has not yet been identified, and the rate at which DUS surveillance prompts intervention is unknown. Multiple calls for decreasing health care spending that does not provide value, including unnecessary testing, have been made. The purpose of this study was to examine the rate of intervention prompted by surveillance DUS on the ipsilateral or contralateral carotid artery after CEA and determine the value of continued surveillance by determining the rate of DUS-prompted intervention. METHODS: A single-center, retrospective chart review of all patients older than 18 years who had undergone CEA from August 2009 to July 2022 was performed. Patients with at least one postoperative duplex in our Intersocietal Accreditation Council-accredited ultrasound lab were included. Exclusion criteria were patients with incomplete medical charts or patients who underwent a concomitant procedure. The primary end point was return to the operating room for subsequent intervention based on abnormal surveillance DUS findings. Secondary end points were the number of postoperative surveillance duplexes, duration of surveillance, and incidence of perioperative stroke. The study participant data were queried for patients who had a diagnosis of stroke that occurred following their procedure. RESULTS: A total 767 patients, accounting for 771 procedures, were included in this study, which resulted in 2145 ultrasound scans. A total of 40 (5.2%) patients required 44 subsequent interventions that were prompted by DUS surveillance scans. The average number of ultrasound scans per patient was 2.8 (range: 0-14), and the average duration of surveillance was 26.4 months (range: 0-155 months). Of the 767 patients, 669 (87.2%) had a unilateral CEA. A total of 62 of 767 (8.1%) patients had planned endarterectomies on the contralateral side based on initial imaging, not prompted by interval DUS surveillance scans. Of 767 patients, 28 (3.7%) patients who underwent CEA had a subsequent procedure for progression of contralateral disease, which was prompted by duplex surveillance scans. The average duration between index CEA and intervention on contralateral carotid was 29.57 months (range: 3-81 months). A total of 11 patients, accounting for 12 procedures, underwent a subsequent procedure for restenosis of their ipsilateral carotid, prompted by duplex surveillance scans. The average duration between index CEA and reintervention on the ipsilateral carotid was 17.9 months (range: 4-70 months). Three of 767 (0.4%) patients in total were identified as having a perioperative stroke. CONCLUSIONS: The overall rate of ipsilateral reintervention after CEA is low. A small percentage of patients will progress their contralateral disease, ultimately requiring surgical intervention. These data suggest that regular duplex surveillance after CEA is warranted for patients with at least moderate contralateral disease; however, the yield is low for ipsilateral restenosis after 36 months based on this single institution study. Further study is needed to better delineate which patients need follow-up to decrease unnecessary testing while still targeting patients most at risk of restenosis or contralateral progression of disease.

Popliteal pseudoaneurysm in a young patient with multiple hereditary exostosis.

Multiple hereditary exostosis is an osteogenic disorder that causes outgrowths of cartilaginous bone tumors that are associated with adjacent neurovascular compressive injuries. We present the case of an adolescent male with multiple hereditary exostosis complicated by popliteal pseudoaneurysm formation who underwent excision of the osteochondroma and vein patch angioplasty repair of the artery. We highlight the rare association between this genetic disease and subsequent vascular complications and review the available literature of arterial complications of this disease.

Percutaneous deep vein arterialization using off-the-shelf devices for chronic limb threatening ischemia.

We present the case of a young man with severe comorbidities who presented with gangrene and rest pain of his right foot. He had already undergone a contralateral below knee amputation for a nonsalvageable left foot due to chronic limb threatening ischemia. We performed percutaneous deep vein arterialization using off-the-shelf devices to attempt limb salvage of his right foot.

Operative Case Volume for Vascular Integrated Residents and Fellows Following the Elective Surgery Shutdown due to COVID-19.

In response to the COVID-19 pandemic, nonemergent surgery was postponed in efforts to limit disease spread. To determine whether these changes affected vascular integrated resident (VR) and fellow (VF) operative volume, Accreditation Council for Graduate Medical Education (ACGME) case log data was reviewed. Case volume and standard deviation for each major category was for graduates of 2020 and 2021 were compared to the year prior to the pandemic, 2019. There were only 3 significant changes when comparing 2020/2021 to the prepandemic baseline of 2019, with increase in abdominal obstructive cases for VRs (8.1 in 2021 vs 5.9 in 2019, P = .021), an increase in upper extremity cases for VFs (18.9 in 2021 from 15.8 in 2019, P = .029), and a decrease in venous cases for VFs (39.6 in 2021 from 48.4 in 2019, P = .011). Postponing nonemergent surgery did not translate to significant changes in operative cases for graduating VRs and VFs.

Postamputation diagnosis of squamous cell carcinoma in a patient with lymphedema.

Chronic lymphedema is fraught with morbidity, including tissue loss. We present the case of a woman with long-standing lymphedema suffering from nonhealing ulcerations despite multiple interventions, who underwent below-knee amputation. Surgical pathology yielded a diagnosis of invasive squamous cell carcinoma. We highlight the uncommon association between lymphedema and squamous cell carcinoma, and the importance of routine pathological testing with lower extremity amputations.

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.

Impact of thoracic endovascular aortic repair timing on outcomes after uncomplicated type B aortic dissection in the Society for Vascular Surgery Vascular Quality Initiative postapproval project for dissection.

OBJECTIVE: The timing of thoracic endovascular aortic repair (TEVAR) after the onset of uncomplicated acute type B aortic dissection (uTBAD) remains controversial. The objective of this study was to evaluate the Society for Vascular Surgery Vascular Quality Initiative (VQI) postapproval study (VQI PAS) data for the impact of TEVAR timing for uTBAD on early and late outcomes, including mortality, procedural complications, and long-term reintervention. METHODS: The VQI PAS used for this analysis includes a total of 606 patients. Patients with uTBAD (defined as those without rupture or malperfusion) exclusive of cases categorized as emergent (N = 206) were divided into groups defined by the Society for Vascular Surgery/Society of Thoracic Surgeons reporting guidelines based on the timing of treatment after the onset of dissection: within 24 hours (N = 8), 1 to 14 days (N = 121), and 15 to 90 days (N = 77). Univariate and multivariable analysis were used to determine differences between timing groups for postoperative mortality, in-hospital complications, and reintervention. RESULTS: Demographics and comorbid conditions were very similar across the 3 TEVAR timing groups. Notable differences included a higher prevalence of baseline elevated creatinine (>1.8 mg/dL)/chronic end-stage renal disease and designation as "urgent" in the <24-hour group, as well as a higher rate of preoperative ß-blocker therapy in the 1- to 14-day group. Postoperative stroke, congestive heart failure, and renal ischemia were more common in the <24-hour group without an increase in mortality. Unadjusted 30-day mortality across groups was lowest in the early TEVAR group (0%, 3.3%, and 5.2%; P = .68), as was 1-year mortality (0%, 8.3%, and 18.2%; P = .06), although not statistically different at any time point. Reintervention out to 3 years was not different between the groups. Multivariable analysis demonstrated the need for a postoperative therapeutic lumbar drain to be the only a predictive risk factor for mortality (hazard ratio = 7.595, 95% confidence interval: 1.730-33.337, P = .007). When further subdivided into patients treated 1 to 7 days or 8 to 14 days after dissection, findings were similar. CONCLUSIONS: Patients with uTBAD treated within 24 hours were unusual (N = 8), too small for valid statistical comparison, and likely represent a high-risk subgroup, which is manifested in a higher risk of complications. Although there was a trend toward improved survival in the acute (1- to 14-day) phase, outcomes did not differ compared with the subacute (15- to 90-day) phase with relation to early mortality, postoperative complications, or 1-year survival. These data suggest that the proper selection of patients for early TEVAR can result in equivalent survival and early outcomes.

A forensic analysis of spin-off and downstream revenue in an academic vascular surgery practice: Unveiling the "vascular X-factor" in a tertiary health care system.

BACKGROUND: Owing to the high level of patient and operative complexity, vascular surgery represents a major driver for elevating case mix index within health care institutions. Although several specialty services are recruited in the care of these patients, it has been difficult to quantify the financial impact of these vascular patient across the health care enterprise. This study aims to quantify all revenues attributable to the introduction of vascular surgery patients within a tertiary health care system. METHODS: Billing data from 2017 to 2020 for all new vascular surgery patients entering a tertiary health care system were captured, and segregated by encounter type--inpatient versus outpatient. Within these major categories, vascular revenue streams were analyzed according to procedural pathology types, such as aneurysm, peripheral vascular disease, cerebrovascular, and venous. Subsequent revenues for nonvascular services were also captured for both inpatient and outpatient encounters that were tied to the initial vascular surgical encounter. Revenues attributable to vascular patients were analyzed and followed with respect to other hospital service lines. RESULTS: A total of 1115 new patients were introduced to the health care system for the first time by vascular surgery. These new patients generated more than $26 million in gross revenue and more than $10 million in contribution margin to the hospital during this time interval in aggregate. From a procedural standpoint, aortic surgery generated more than $7.4 million in revenue and $2.9 million in health system contribution margin. Peripheral vascular disease contributed $7.3 million and $2.6 million in revenue and contribution margins, respectively. Aortic surgery cases generated the highest margin per encounter encompassing the total sum of contributions. Subtracting all revenue attributable to vascular billing (spin-off), new patients brought in by vascular generated $9.6 million in revenue and $4.3 million in contribution margin from other service lines. Vascular access procedures produced the greatest spin-off margin per encounter at $10,985, and ancillary inpatient/outpatient generated the greatest number of spin-off encounters (n = 597) and revenue ($8,181,708). CONCLUSIONS: Patients introduced by a tertiary care vascular surgery program produce a significant revenue/margin for the parent health care system. When considering the fiscal health of a vascular program within a tertiary health care system, spin-off and downstream revenue should be considered in terms of overall value.

Five-year results of the STABLE II study for the endovascular treatment of complicated, acute type B aortic dissection with a composite device design.

OBJECTIVE: To provide the 5-year outcomes of the use of a composite device (proximal covered stent graft + distal bare stent) for endovascular repair of patients with acute, type B aortic dissection complicated by aortic rupture and/or malperfusion. METHODS: Study of Thoracic Aortic Type B Dissection Using Endoluminal Repair (STABLE) II was a prospective, multicenter study of the Zenith Dissection Endovascular System (William Cook Europe). Patients were enrolled between August 2012 and January 2015 at sites in the United States and Japan. Five-year follow-up was completed by January 2020. RESULTS: In total, 73 patients (mean age: 60.7 ± 10.9 years; 65.8% male) with acute type B dissection complicated by malperfusion (72.6%), rupture (21.9%), or both (5.5%) were enrolled. Patients were treated with either a composite device (79.5%) or the proximal stent graft alone (no distal bare stent, 20.5%). Dissections were more extensive in patients who received the composite device (408.9 ± 121.3 mm) than in patients who did not receive a bare stent (315.9 ± 100.1 mm). The mean follow-up was 1209.4 ± 754.6 days. Freedom from all-cause mortality was 80.3% ± 4.7% at 1 year and 68.9% ± 7.3% at 5 years. Freedom from dissection-related mortality remained at 97.1% ± 2.1% from 1-year through 5-year follow-up. Within the stent-graft region, the rate of either complete thrombosis or elimination of the false lumen increased over time (82.1% of all patients at 5 years vs 55.7% at first postprocedure computed tomography), with a higher rate at 5 years in patients who received the composite device (90.5%) compared with patients without the bare stent (57.1%). Throughout the follow-up, overall true lumen diameter increased within the stent-graft region, and overall false lumen diameter decreased. At 5 years, 20.7% of patients experienced a decrease in maximum transaortic diameter within the stent-graft region, 17.2% experienced an increase, and 62.1% experienced no change. Distal to the treated segment (but within the dissected aorta), 23.1% of patients experience no change in transaortic diameter at 5 years; a bare stent was deployed in all these patients at the procedure. Five-year freedom from all secondary intervention was 70.7% ± 7.2%. CONCLUSIONS: These 5-year outcomes indicate a low rate of dissection-related mortality for the Zenith Dissection Endovascular System in the treatment of patients with acute, complicated type B aortic dissection. Further, these data suggest a positive influence of composite device use on false lumen thrombosis. Continuous monitoring for distal aortic growth is necessary in all patients.

Retrograde type A dissection in the Vascular Quality Initiative thoracic endovascular aortic repair for dissection postapproval project.

BACKGROUND: Retrograde dissection (RD) can be a serious complication after thoracic endovascular aortic repair (TEVAR), with retrograde type A dissection (RTAD) particularly life-threatening. Prior studies have suggested that treatment timing, anatomic characteristics, device selection, and procedural conduct of TEVAR performed for type B aortic dissection could mitigate the occurrence of RD. The Vascular Quality Initiative TEVAR for Dissection Registry is an ongoing project meant to satisfy Food and Drug Administration requirements for postmarket approval surveillance of the Gore conformable TAG thoracic endoprosthesis (W.L. Gore & Associates, Flagstaff, Ariz), Medtronic Valiant thoracic stent graft (Medtronic, Santa Rosa, Calif), and Cook Medical dissection devices (Cook Medical, Bloomington, Ind) and provides a unique source of evaluation for RTAD in a prospectively collected real-world registry. METHODS: A total of 588 consecutive patients at 49 institutions had undergone TEVAR for acute (<30 days; n = 336) and chronic (≥30 days; n = 252) type B aortic dissection were included. The occurrence of RD as reported by the participating centers and de-identified source documents were reviewed and confirmed independently by two of us (A.W.B. and G.W.). The demographics, procedural and device data, and anatomic considerations were evaluated, and the devices were grouped in a de-identified manner as Gore, Medtronic, and other. RESULTS: The mean follow-up was 889 days (median, 658 days), and 408 patients had completed follow-up data available for >1 year. A total of 19 patients with RD (3.2%) were identified, 9 of whom had been treated for acute and 10 for chronic dissection, a 2.7% and 4.0% incidence, respectively (P = .48, acute vs chronic). Of the 19 RD cases, 15 were RTAD, 6 after treatment of acute and 9 after treatment of chronic dissection, a 1.8% and 3.6% incidence, respectively (P = .19, acute vs chronic). Five cases of RD had occurred intraoperatively (four of which were RTAD). The median time to RD and RTAD was 62 and 69 days, respectively (range, 0 to 1600 days). Of the 15 patients with RTAD, 12 had undergone surgical repair and 2 had not undergone repair; the treatment of one was unknown. The overall mortality was 33.3% (5 of 15). The factors associated with RTAD included more extensive dissection (mean, 5.6 zones without RTAD vs 8.5 zones with RTAD; P = .001), female sex (28.3% female without RTAD vs 53.3% with RTAD; P = .04), and non-White race (62.7% White without RTAD vs 33.3% White with RTAD; P = .05). Mean oversizing was not significantly different for those without RTAD compared with that for those with RTAD (14.0% vs 14.2%; P = .92). The device type was anonymized in this project; however, we found no significant differences between the Gore, Medtronic, and all other devices. CONCLUSIONS: The rate of RD in the present real-world postapproval project was consistent with that from previously reported studies, including highly controlled pivotal studies. Device type was not predictive of RD, and the newly identified risk factors for RTAD include more extensive dissection and a trend toward a greater risk for female sex and non-White race.

Intraoperative blood pressure lability carries a higher risk of headache after carotid endarterectomy.

OBJECTIVE: Cerebral hyperperfusion syndrome (CHS) is a rare but potentially devastating complication after carotid endarterectomies (CEA). Its symptoms range from new-onset unilateral headache (HA) to intracranial hemorrhage (ICH). Risk factors for CHS in the literature to date have not yet yielded a consensus. This study examines intraoperative and postoperative blood pressure variations as potential risk factors for HA. METHODS: A single-center retrospective review at a tertiary care center from January 2010 to November 2019 was performed. Inclusion criteria were all patients undergoing CEA for symptomatic or asymptomatic carotid disease. Patients with incomplete charts were excluded. Primary endpoints were new-onset unilateral HA or postoperative ICH. Data on intraoperative and postoperative mean arterial pressure (MAP), systolic blood pressure (SBP), the mode of endarterectomy, shunt placement, and contralateral carotid status were collected. RESULTS: There were 735 patients who met the inclusion criteria: 430 patients underwent modified eversion CEA (59%) and 305 patients for patch angioplasty (42%). The incidence of HA was 19% (n = 142) in our total cohort. Of the 19% with HA, 1.5% (n = 11) demonstrated no relief with analgesics and strict blood pressure control; noncontrast head computed tomography scans were performed subsequently. One patient (0.1%) had an ipsilateral ICH. Univariate analysis demonstrated that greater intraoperative MAP peak had the highest risk for HA (odds ratio [OR], 1.014; 95% confidence interval [CI], 1.007-1.022; P = .0002), followed by intraoperative MAP variability (OR, 1.011; 95% CI,1.005-1.018; P ≤ .0008), and peak intraoperative SBP (OR, 1.01; 95% CI, 1.004-1.015; P = .0011). An unpaired Student t test identified change in intraoperative MAP (P < .005), change in the SBP (P < .005), and peak SBP (P < .001) were significantly associated with HA. Interestingly, there was no significant difference between postoperative MAP variability and HA (P = .1). The mode of endarterectomy showed no statistically significant difference in risk for developing HA (OR, 1.165; 95%; 95% CI, 0.801-1.694; P = .42). CONCLUSIONS: Greater intraoperative variability in blood pressures are significantly associated with a higher risk of HA. Adhering to stricter intraoperative blood pressure parameters and limiting blood pressure variability may be beneficial at decreasing the incidence of CHS and its complications.

Midterm outcomes of 455 patients receiving the AFX2 endovascular graft for the treatment of abdominal aortic aneurysm: A retrospective multi-center analysis.

Since being introduced into clinical practice the AFX family of endografts has undergone labelling updates, design and manufacturing changes to address a Type III failure mode. The published literature on the performance of the current endograft-AFX2 -is limited to small series with limited follow up. The present study reports the largest series of patients implanted with AFX2 for the treatment of abdominal aortic aneurysms. The study was a retrospective, 5 center study of patients receiving an AFX2 endograft from January 2016 until Dec 2020. Electronic case report forms were provided to four of the centers, with one additional site providing relevant outcomes in an independent dataset. Relevant outcomes were reported via Kaplan-Meier analysis and included all-cause mortality, aneurysm-related mortality, post EVAR aortic rupture, open conversion, device related reinterventions and endoleaks. Among a cohort of 460 patients, 405 underwent elective repair of an AAA, 50 were treated for a ruptured AAA, and 5 were aorto-iliac occlusive disease cases. For the elective cohort (mean age 73.7y, 77% male, mean AAA diameter 5.4cm), the peri-operative mortality was 1.7%. Freedom from aneurysm-related mortality was 98.2% at 1,2,3 and 4 years post-operatively, there were no post-operative aortic ruptures, and 2 patients required open conversion. Freedom from Type Ia endoleaks was 99.4% at 1, 2, 3 and 4 years. Freedom from Type IIIa and Type IIIb endoleaks were 100% and 100% (year 1), 100% and 99.6% (year 2), 99.4% and 99.6% (year 3), 99.4% and 99.6% (year 4) respectively. Freedom from all device-related reintervention (including Type II endoleaks) at 4 y was 86.8%. The AFX2 endograft appears to perform to a satisfactory standard in terms of patient centric outcomes in mid-term follow up. The Type Ia and Type III endoleaks rates at 4y appear to be within acceptable limits. Further follow up studies are warranted.

Effect of proximal fixation length on complications after endovascular repair of type B aortic dissection.

OBJECTIVE: We evaluated the effect of the achieved proximal seal length on the outcomes after endovascular repair of acute type B aortic dissection (aTBAD). METHODS: A post hoc analysis was performed using data from two prospective, multicenter investigational studies of the Zenith Dissection Endovascular System (STABLE I and II). Patients treated for aTBAD within 14 days of symptom onset were included if complete preoperative and postoperative imaging data were available for review. The patients were divided into four groups according to the length of the achieved proximal seal according to the centerline imaging findings: ≥20 mm, ≥10 to <20 mm, ≥0 to <10 mm, and <0 mm. The outcomes stratified by the achieved proximal seal length were evaluated. All imaging findings were based on core laboratory analysis. RESULTS: A total of 110 patients were included in the present analysis; 51 were from STABLE I and 59 from STABLE II. Although the study protocol criteria required a ≥20 mm length of nondissected aorta distal to the left common carotid artery to serve as a proximal seal zone, an achieved proximal seal length of ≥20 mm was observed in only 19 of the 110 patients (17.3%) according to the location of stent-graft placement. After a mean follow-up duration of 41.6 ± 21 months, the cumulative rate of the composite device outcome (ie, proximal entry flow, retrograde dissection, transaortic growth, and stent-graft migration) was lowest in patients with an achieved proximal seal length of ≥20 mm (15.8%; 3 of 19). The cumulative rate increased as the seal length decreased (32.0% [8 of 25], 55.6% [20 of 36], and 60.0% [18 of 30] with a proximal seal length of ≥10 to <20 mm, ≥0 to <10 mm, and <0 mm, respectively; P < .01, Cochran-Armitage trend test). CONCLUSIONS: A clear inverse relationship was found between the proximal seal length achieved and associated adverse outcomes. This finding underscores the importance of landing the stent-graft in healthy, nondissected aorta to minimize the risk of complications and provide a durable repair in patients with aTBAD.

Traumatic thoracolumbar projectile with concomitant vertebral body and aortic injury.

Penetrating subdiaphragmatic aortic trauma is associated with high morbidity and mortality with studies having reported a 50%-70% associated mortality. We describe a case of a patient with a subdiaphragmatic aortic injury caused by a 7.4-cm common nail that traversed through his L1 vertebral body into the aorta. His aortic injury was managed jointly with vascular surgery and neurosurgery teams.

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.

Trends in the 10-year history of the vascular integrated residency match: More work, higher cost, same result.

OBJECTIVE: The purpose of this study was to examine trends in application submission, rank lists, and applicant quality for vascular surgery integrated residency. METHODS: The National Resident Matching Program Results and Data reports and the Electronic Residency Application Service Statistics from 2007 to 2017 were compiled and mined for trends in terms of application submission and the number of applicants a program needed to rank to fill all residency positions. Applicant pool depth and percentage of programs applied to were calculated. Outcome data from the National Resident Matching Program were reviewed for 2014 and 2016 for United States Medical Licensing Examination Step scores and experiences. RESULTS: During the last 10 years, the number of vascular surgery integrated residency spots rose from 9 to 60 per year. Most programs offer one spot per year; none offer more than two. The average number of applications received by programs rose from 17 applications in 2008 to 63.8 in 2017. The average rank list depth needed by programs to fill the spots has not increased (range, 2.5-5.1; standard deviation, 0.73). The proportional depth of the applicant pool decreased from 4.6 U.S. and Canadian applicants for every one residency spot in 2008 to 1.7 applicants for every one residency spot in 2017. Applicant quality metrics were available for 2 years (2014 and 2016). Step 1 scores (237/239), Step 2 scores (250/250), research experiences (3.7/4.2), and volunteer experiences (5.9/5.5) remained nearly unchanged. The number of contiguous ranks for matched applicants remained stable (12.3/12.8). CONCLUSIONS: The current system promotes multiple inefficiencies, resulting in application glut. Fewer applicants are flooding programs with an increasing number of applications. More money is being spent on Electronic Residency Application Service applications without changes in the number needed to rank by applicants or programs to achieve a match. There is no improvement in the quality of the applicant. Should these trends continue, they represent an unsustainable model for resident selection.
