Purpose: To determine the anatomical eligibility rate for endovascular repair of ruptured and symptomatic abdominal aortic aneurysms (AAA) using commercially available endografts. Methods: In a retrospective review, 28 preoperative computed tomographic (CT) scans were examined from among 83 patients who underwent surgical repair of a ruptured or acutely symptomatic AAA at a university-based tertiary care center during the past 10 years. The proximal aortic neck, aneurysm, and iliac dimensions were compared to corresponding measurements from 100 preoperative CT scans from patients who underwent elective repair of asymptomatic AAA. Based on expanded selection criteria for the 2 FDA-approved endografts (AneuRx and Ancure), eligibility rates for endovascular repair were compared between patients with ruptured/symptomatic and asymptomatic AAAs. Results: The proximal neck of the ruptured/symptomatic AAAs was on the average 2 mm larger in diameter (25 ± 4 versus 23 ± 3 mm, p=0.04) and 7 mm shorter (16 ± 10 versus 23 ± 14, p=0.017) than asymptomatic AAAs. The maximum AAA diameter was significantly larger in the ruptured/symptomatic group (64 ± 16 mm) than in the asymptomatic group (58 ± 11 mm, p=0.033). Of the 28 ruptured/symptomatic AAAs assessed morphologically, 13 (46%) were anatomically eligible for endovascular repair compared to 74 of the 100 asymptomatic AAAs (p=0.006). The main cause for exclusion was an unfavorable proximal neck, which was present in 15 (54%) of the 28 ruptured/symptomatic AAAs and in 24 (24%) of the 100 asymptomatic AAAs (p = 0.003). Conclusions: A significantly smaller proportion of patients presenting with ruptured/symptomatic AAA are anatomically eligible for endovascular AAA repair compared to patients with asymptomatic AAA due to unfavorable proximal neck anatomy.

Purpose: To evaluate the outcome of aortic endografts deployed in large infrarenal necks and to identify any association of preoperative aneurysm characteristics and postoperative morphological changes with the incidence of neck dilatation and device migration in this patient subset. Methods: The records of 47 patients (41 men; mean age 74, range 55–84) with large aortic neck diameters treated with Talent stent-grafts from 1998 to 2001 were reviewed. Patients with anatomical criteria that precluded aneurysm exclusion with currently available devices were preferentially selected. Mean baseline aneurysm morphology included 27.6-mm (range 18–33.4) suprarenal and 28.1-mm (range 24–34) infrarenal neck diameters; the infrarenal neck length was 26 ± 16 mm with angulation of 37° ± 18°. Computed tomographic (CT) angiograms up to 3 years were analyzed using specialized interactive software; migration was defined as >1-cm change in the distance from the lower renal artery to the top of the device. Pre- and postoperative morphological characteristics of the aneurysm were compared between patients with and without migration. Results: Of the 45 patients successfully treated, 40 had complete CT data for analysis. During a mean 17-month follow-up, 7 (17.5%) of the 40 devices exhibited distal migration. Six patients required secondary procedures; 5 were in the migration cohort. No preoperative anatomical characteristic or degree of neck dilatation over time was predictive of stent-graft migration. Aneurysm sac regression was significant at 1 (–0.09 ± 4.90 mm) and 2 (–1.48 ± 2.56 mm) years in endografts without migration (p<0.001). Distal endograft migration >1 cm predicted the need for secondary interventions (p<0.001), with 83% sensitivity and 94% specificity. Conclusions: Endovascular repair is successful in patients with large infrarenal necks and complex neck morphology. Changes in aneurysm remodeling over time were similar to reported observations in patients with more favorable neck criteria. Although no anatomical factor associated with migration could be identified from this analysis, distal displacement >1 cm correlated with the need for a secondary intervention.

Objectives: To determine the factors associated with the diagnosis of acquired cholesteatoma (AC) in children, we performed a retrospective chart review at a tertiary care center. Methods: We reviewed children with a diagnosis of AC that extended beyond the mesotympanum in the presence of a nonintact tympanic membrane who underwent surgical treatment over a 14-year period. Results: There were 116 children (78 male, 38 female) between 3 and 18 years of age (mean, 9.5 years). Their average period of management in a specialist otolaryngology clinic before the diagnosis of cholesteatoma was made was 3.2 years, and 68% of the children had previously undergone insertion of tympanostomy tubes. Symptoms and signs included chronic otorrhea (59%), recurrent acute otitis media (58%), and conductive hearing loss (51%). The diagnosis of AC was eventually made after office otoscopy (26%), temporal bone computed tomography (24%), or examination under anesthesia (17%). In 33% of children, the diagnosis was made only after surgical exploration of the middle ear and mastoid. Conclusions: Our data underscore the importance of maintaining a high index of suspicion for AC in managing children with long-standing otologic symptoms, and considering otomicroscopy, computed tomographic scanning, or tympanomastoid exploration if medical treatment fails.

Ruptured Abdominal Aortic Aneurysms

Purpose: To assess the anatomical suitability of ruptured abdominal aortic aneurysms (AAA) for emergency endovascular repair. Methods: All cases (46 patients [35 men; mean age 74 years, range 54–85]) in which computed tomographic angiography (CTA) confirmed AAA rupture over a 5-year period at our university hospital were reviewed for anatomical suitability for endovascular repair. Measurements were made by a radiologist experienced in anatomical assessment of CT criteria for elective endovascular aneurysm repair (EVAR). Results: The mean aneurysm neck length was 18 mm (range 0–59); 17 were conical, 13 straight, 4 barrel, and 6 reverse conical. Six cases had no proximal neck. Overall, 37 (80%) patients were unsuitable for EVAR according to our criteria. Nearly half the patients (22, 48%) had ≥2 adverse features. Unsuitable neck morphology (35, 76%) was the primary reason for exclusion, but CIA aneurysm (10, 22%) and EIA tortuosity (7, 15%) were secondary adverse features. Conclusions: With current stent-graft design, the majority of ruptured abdominal aortic aneurysms are anatomically unsuitable for endovascular repair.

AbstractCongenital abdominal aortic aneurysms are rare but have chronic and life-threatening sequelae including hypertension, thromboses, and death. A fetal ultrasound at 27 weeks’ gestation diagnosed a giant abdominal aortic aneurysm. The patient delivered at another tertiary care center where pediatric cardiovascular surgery care was available. Her term 3096-g female infant developed hypertension, biventricular hypertrophy, and right kidney ischemia. She underwent surgical repair at 2 months of life but subsequently lost all residual renal function and was not a candidate for dialysis. Support was withdrawn and she expired. Although isolated fetal AAA is rare, prenatal diagnosis is feasible and facilitates early referral for multi-disciplinary postnatal care. Outcome depends on the size and location of the aneurysm as well as on peri-operative complications.

OBJECTIVEThe authors reviewed the transfer requests for isolated pediatric traumatic brain injuries (TBIs) at a Level I/II facility with the goal of identifying clinical and radiographic traits associated with potentially avoidable transfers that could be safely managed in a non–tertiary care setting.METHODSThe authors conducted a retrospective study of patients < 18 years of age classified as having TBI and transferred to their Level I tertiary care center over a 12-year period. The primary outcome of interest was identifying potentially avoidable transfers, defined as transfers of patients not requiring any neurosurgical intervention and discharged 1 hospital day after admission.RESULTSOverall, 70.8% of pediatric patients with isolated TBI did not require neurosurgical intervention or monitoring, indicating an avoidable transfer. Potentially avoidable transfers were associated with outside hospital imaging that was negative (86%) or showed isolated, nondisplaced skull fractures (86%) compared to patients with cranial pathology (53.8%, p < 0.001) as well as age ≤ 6 years (81% [negative imaging/isolated, nondisplaced fractures] vs 54% [positive cranial pathology], p < 0.001). The presence of headaches, nonfocal deficits, and loss of consciousness were associated with necessary transfer (p < 0.05). Patients with potentially avoidable transfers underwent frequent repeat CT studies (19.1%) and admissions to the pediatric intensive care unit (55.9%) but at a lower rate than those whose transfers were necessary (p < 0.001). Neurosurgical interventions occurred in 11% of patients with cranial pathology, which accounted for 17.9% of necessary transfers and 5.2% of all transfers.CONCLUSIONSIn the authors’ region, potentially up to 70% of interfacility transfers for pediatric brain trauma in the absence of other systemic injuries warranting surgical intervention may not require neurosurgical intervention and could be managed locally. No patients transferred with isolated, nondisplaced skull fractures or negative CT scans required neurosurgical intervention, and 86% were discharged the day after admission. In contrast, 11% of patients with CT scans indicative of cranial pathology required neurosurgical intervention. Age > 6 years, loss of consciousness, and nonfocal deficits were associated with a greater likelihood of needing a transfer. Further studies are required to clarify which patients can be managed at local institutions, but referring centers should practice overcaution given the potential risks.

Purpose: To test the hypothesis that stent-graft support influences sac shrinkage independent of endoleak rates after endovascular repair of abdominal aortic aneurysms (AAA). Methods: Ninety AAA patients underwent treatment with bifurcated endoluminal devices at our institution between October 1996 and February 1999. Fifty-two patients were treated using a nonsupported (NS) Ancure endograft and 38 using a fully supported (FS) Excluder endograft. Computed tomographic (CT) scans were obtained during the first postoperative month and at 6, 12, and 24-month intervals. Aneurysm diameter was measured as the minor axis of the largest AAA axial slice on the CT scan. Six, 12, and 24-month sac sizes were compared to the first postoperative evaluation. Results: Successful endoluminal graft placement was accomplished in all patients. The two groups were matched for age, anatomical criteria, and comorbidities except for baseline AAA size: the mean diameter was 5.4 cm in the NS group and 5.0 cm for the FS group (p<0.01). Endoleak rates were 25% (13/52) in the NS group and 18% (7/38) in the FS group (p<0.05) at 1 month. All endoleaks that did not resolve spontaneously at 6 months were treated. Initial endoleak status did not affect the sac shrinkage rates at the 12 and 24-month evaluations. At 2 years, the NS group had greater shrinkage of the sac (1.2 cm) versus the FS cohort (0.3 cm, p<0.05). In addition, more patients in the NS group had sac shrinkage >5 mm (83% versus 18%, p<0.05). Conclusions: Despite a higher endoleak rate, the nonsupported Dacron Ancure endografts were associated with greater sac shrinkage at up to 24 months following implantation.

Objectives Stent grafts for endovascular repair of infrarenal aneurysms are commercially available for aortic necks up to 32 mm in diameter. The aim of this study was to evaluate the feasibility of endovascular repair with large thoracic stent grafts in the infrarenal position to obtain adequate proximal seal in wider necks. Methods All patients who underwent endovascular aneurysm repair using thoracic stent grafts with diameters greater than 36 mm between 2012 and 2016 were included. Follow-up consisted of CT angiography after six weeks and annual duplex thereafter. Results Eleven patients with wide infrarenal aortic necks received endovascular repair with thoracic stent grafts. The median diameter of the aneurysms was 60 mm (range 52–78 mm) and the median aortic neck diameter was 37 mm (range 28–43 mm). Thoracic stent grafts were oversized by a median of 14% (range 2–43%). On completion angiography, one type I and two type II endoleaks were observed but did not require reintervention. One patient experienced graft migration with aneurysm sac expansion and needed conversion to open repair. Median follow-up time was 14 months (range 2–53 months), during which three patients died, including one aneurysm-related death. Conclusions Endovascular repair using thoracic stent grafts for patients with wide aortic necks is feasible. In these patients, the technique may be a reasonable alternative to complex endovascular repair with fenestrated, branched, or chimney grafts. However, more experience and longer follow-up are required to determine its position within the endovascular armamentarium.

Objectives To evaluate the use of chimney grafts in the treatment of para-anastomotic aneurysms after previous abdominal aortic aneurysms open repair with short neck. Methods A retrospective analysis of prospectively collected data of consecutive patients who underwent endovascular repair for proximal aortic para-anastomotic aneurysms following previous open repair for infrarenal abdominal aortic aneurysms was performed. All included patients had a short infrarenal aortic neck (<10 mm) excluding standard endovascular aortic repair. Five patients were symptomatic at the admission needed urgent treatment. Results Twelve patients with para-anastomotic aneurysms underwent placement of chimney grafts. The median time between the original operations to redo endovascular procedure was 11 years (interquartile range, 9.5 years). The mean infrarenal length was 4.3 mm (1–9 mm). A total of 28 chimneys grafts were deployed for the 12 patients. The technical success rate was 91.7%. At a median radiologic follow-up of 16 months (2.0–29.4, 95% confidence interval), one patient died, while two late endoleaks and two reinterventions at one and three years for type Ia endoleak were performed by proximal extension and triple chimney graft placement. Conclusion The results of the present study show that ch-endovascular aortic repair is a safe technique for patients who suffered from proximal para-anastomotic aneurysms and having short neck unsuitable for standard endovascular repair. Longer follow up warranted to evaluate the durability of ch-endovascular aortic repair for this specific indication.
