An Endovascular Approach to Abdominal Aortic Aneurysm Rupture is Associated With Improved Outcomes for Patients With Prior Aortic Repair.

OBJECTIVE: To assess whether outcomes of rupture repair differ by aortic repair history and determine the ideal approach for rupture repair in patients with previous aortic repair. METHODS: This retrospective review included all patients who underwent repair of a ruptured infrarenal abdominal aortic aneurysm from 2003 - 2021 recorded in the Vascular Quality Initiative (VQI) registry. Pre-operative characteristics and post-operative outcomes and long term survival were compared between patients with and without prior aortic repair. To assess the impact of open and endovascular approaches to rupture, a subgroup analysis was then performed among patients who ruptured after a prior infrarenal aortic repair. Univariable and adjusted analyses were performed to account for differences in patient characteristics and operative details. RESULTS: A total of 6 197 patients underwent rupture repair during the study period, including 337 (5.4%) with prior aortic repairs. Univariable analysis demonstrated an increased 30 day mortality rate in patients with prior repairs vs. without (42 vs. 36%; p = .034), and prior repair was associated with increased post-operative renal failure (35 vs. 21%; p < .001), respiratory complications (32 vs. 24%; p < .001), and wound complications (9 vs. 4%; p < .001). Following adjustment, all outcomes were similar with the exception of bowel ischaemia, which was decreased among patients with prior repair (OR 0.7, 95% CI 0.6 - 0.9). Subgroup analysis demonstrated that patients with a prior aortic repair history who underwent open rupture repair had increased odds for 30 day death (OR 1.3, 95% CI 1.2 - 1.7) and adverse secondary outcomes compared with those managed endovascularly. CONCLUSION: Prior infrarenal aortic repair was not independently associated with increased morbidity or mortality following rupture repair. Patients with a prior aortic repair history demonstrated statistically significantly higher mortality and morbidity when treated with an open repair compared with an endovascular approach. An endovascular first approach to rupture should be strongly encouraged whenever feasible in patients with prior aortic repair.

Operative repair of right intrathoracic subclavian artery aneurysms in patients with genetic arteriopathy.

True intrathoracic subclavian artery aneurysms (SCAAs) are rare and have various etiologies. Right intrathoracic SCAAs pose specific anatomic challenges to repair. We present three different operative approaches, open, endovascular, and hybrid repair, for the repair of a right intrathoracic SCAA in three patients with genetic arteriopathy: Marfan syndrome, vascular Ehlers-Danlos syndrome, and unspecified Ehlers-Danlos syndrome, respectively. These cases demonstrate an individualized operative approach based on the genetic diagnosis for each patient presenting with a right intrathoracic SCAA.

Preoperative risk score accuracy confirmed in a modern ruptured abdominal aortic aneurysm experience.

OBJECTIVE: Various risk score calculators used to predict 30-day mortality after treatment of ruptured abdominal aortic aneurysms (rAAAs) have produced mixed results regarding their usefulness and reproducibility. We prospectively validated the accuracy of our preoperative scoring system in a modern cohort of patients with rAAAs. METHODS: A retrospective review of all patients wiith rAAAs who had presented to a single academic center from January 2002 to December 2018 was performed. The patients were divided into three cohorts according to when the institutional practice changes had occurred: the pre-endovascular aneurysm repair (EVAR) era (January 2002 to July 2007), the pre-Harbor View risk score era (August 2007 to October 2013), and the modern era (November 2013 to December 2018). The primary outcome measure was 30-day mortality. Our preoperative risk score assigns 1 point for each of the following: age >76 years, pH <7.2, creatinine >2 mg/dL, and any episode of hypotension (systolic blood pressure <70 mm Hg). The previously reported mortality from a retrospective analysis of the first two cohorts was 22% for 1 point, 69% for 2 points, 78% for 3 points, and 100% for 4 points. The goal of the present study was to prospectively validate the Harborview scoring system in the modern era. RESULTS: During the 17-year study period, 417 patients with rAAAs were treated at our institution. Of the 118 patients treated in the modern era, 45 (38.1%) had undergone open aneurysm repair (OAR), 61 (51.7%) had undergone EVAR, and 12 (10.2%) had received comfort measures only. Excluding the 12 patients without aneurysm repair, we found a statistically significant linear trend between the preoperative risk score and subsequent 30-day mortality for all patients combined (P < .0001), for OAR patients alone (P = .0003), and for EVAR patients alone (P < .0001). After adjustment for the Harborview risk score, the 30-day mortality was 41.3% vs 31.6% after OAR vs EVAR, respectively (P = .2). For all repairs, the 30-day mortality was 14.6% for a score of 0, 35.7% for a score of 1, 68.4% for a score of 2, and 100% for a score of 3 or 4. CONCLUSIONS: Our results, representing one of the largest modern series of rAAAs treated at a single institution, have confirmed the accuracy of a simple 4-point preoperative risk score in predicting 30-day mortality in the modern rAAA patient. Such tools should be used when discussing the treatment options with referring physicians, patients, and their family members to help guide transfer and treatment decision-making.

Endoscopic transpapillary stenting for the management of acute cholecystitis.

INTRODUCTION: Cholecystectomy is the gold standard treatment of acute cholecystitis. Patients who are considered not to be candidates for cholecystectomy are commonly recommended to undergo percutaneous transhepatic gallbladder drainage (PTGBD) tube placement; however, external drainage is undesirable for many patients. Endoscopic transpapillary stent placement (ETSP) has been described as an alternative method for decompression of the gallbladder. Data in support of this technique is limited to a handful of observational studies with variable indications. Our study sought to expand on the available data for the use of ETSP exclusively in the context of acute cholecystitis. METHODS: We performed a retrospective chart review of patients with cholecystitis who underwent ETSP at our institution between January 2012 and July 2018. We collected data on indication, comorbidities, length of stay, laboratory values, outcomes, additional procedures, and whether cholecystectomy was eventually performed. RESULTS: During the study period, 12 patients underwent ETSP. The mean age was 68.2 years (± SD 12.4) with an average Anesthesia Society Assessment (ASA) class of 3.2. The Charlson Comorbidity Index was greater than seven in 75% of patients, indicating a 0% estimated 10-year survival. The National Surgical Quality Improvement Program (NSQIP) surgical risk calculator was used to estimate an average mortality risk for laparoscopic cholecystectomy of 4.8% (± 3.3, 95% CI) in our study population; the estimated risk in the general population is 0.1%. Immediate resolution of symptoms with endoscopic drainage was achieved in 11 of 12 patients (91.7%); one patient experienced no symptom resolution with endoscopic drainage nor subsequent PTGBD tube placement. Six of 12 (50%) patients experienced recurrence of symptoms requiring hospitalization, and two of 12 patients (16.7%) died secondary to biliary sepsis. CONCLUSION: Endoscopic transpapillary stent placement is an alternative method for the management of acute cholecystitis patients who are not candidates for surgery. ETSP has a high technical success rate; however, it may result in a high rate of symptom recurrence and should only be utilized in select patients. Randomized studies would be beneficial to further investigate the utility and safety of ETSP in the management of acute cholecystitis.

Outcomes following early versus delayed cholecystectomy performed for acute cholangitis.

BACKGROUND: Early cholecystectomy following an episode of gallstone pancreatitis is data supported, however, there is minimal literature regarding the optimal timing for cholecystectomy following an episode of acute cholangitis. Our study aims to determine the ideal timing for laparoscopic cholecystectomy following an episode of acute cholangitis. METHODS: A retrospective chart review was done on cholecystectomies performed for cholangitis at our institution from 2008 to 2015. Patients were compared based on timing of cholecystectomy (i.e., index admission versus delayed) and Tokyo severity grade (I-III). RESULTS: We identified 151 patients who underwent cholecystectomy for cholangitis at our institution from 2008 to 2015. Cholecystectomy was performed during the index admission for 61.6% of patients and Tokyo grade (TG) did not affect the rate of cholecystectomy during index admission (TG1 65.2%, TG2 64.1%, TG3 52.8%; p = 0.46). There was no difference in average operative time (89.0 min vs. 96.6 min; p = 0.36) or conversion to open cholecystectomy (5.4% vs. 10.3%; p = 0.34) between early and late cholecystectomy groups. There was also no statistically significant difference in intra-operative complications (9.7% vs. 15.5%; p = 0.28) or overall complication rates (16.1% vs. 29.3%; p = 0.05) based on timing of cholecystectomy; however, post-operative complications were significantly higher for the delayed cholecystectomy group (20.7% vs. 6.5%; p = 0.01). CONCLUSIONS: Early cholecystectomy after cholangitis is safe to perform and is not associated with higher operative times or rate of conversion to open, regardless of Tokyo grade. Due to the risk of developing recurrent cholangitis and a higher rate of post-operative complications seen with delayed cholecystectomy, our recommendation is to perform cholecystectomy during the index admission.

Cystic Adventitial Disease of the Common Femoral Vein Successfully Treated with Resection, Synthetic Graft Reconstruction, and Fistula Creation.

Cystic adventitial disease (CAD) is a rare, benign disease of blood vessels which most commonly affects the popliteal artery. Less than 50 cases of CAD affecting veins have ever been described in the literature to date. We report the case of a 56-year-old woman who presented with unilateral lower extremity swelling and varicosities due to CAD of her common femoral vein. Resection and reconstruction with a venous interposition graft, employing a polytetrafluoroethylene graft and arteriovenous fistula in order to maintain venous bypass patency, were performed successfully. The patient recovered well without any evidence of recurrence or postoperative complications.

Ischemic Toe Ulceration Due to Foreign Body Embolus From Hydrophilic Polymer-Coated Intravascular Device.

Hydrophilic polymer coatings are now widely applied to catheters and other intravascular devices used in neurovascular, cardiovascular, and peripheral vascular procedures. Emboli consisting of these materials have been previously identified in biopsies and autopsies following pulmonary infarction, stroke, gangrene, or death. We report a case involving a nonhealing foot ulcer that appeared following cardiac catheterization, stenting, and automatic implanted cardiac defibrillator (AICD) implantation in a patient without other evidence of significant peripheral artery disease. An 85-year-old woman with chronic atrial fibrillation, aortic valve stenosis, and coronary artery disease underwent coronary stenting and AICD implantation for ventricular tachycardia and syncope. She developed a toe ulcer shortly thereafter, which did not respond to standard treatment. A histological examination following amputation of the toe found amorphous basophilic material in capillaries adjacent to the edge of the ulcer, which was similar to material associated with hydrophilic polymer coatings. Ischemia and infarcts following endovascular procedures should not be presumed to result from thrombus or vascular disease, even if intravascular devices appear intact or properly placed after the procedure. To help establish the incidence of ischemia caused by hydrophilic polymer device coatings, if excision of ischemic or infarcted tissue after endovascular procedures using coated devices becomes necessary, the tissue should be evaluated microscopically. Surgeons should also consider the tolerance of distal organs to infarct or ischemia when selecting coated intravascular devices.

Overuse of Previsit Ultrasound in Patients Referred for Treatment of Inguinal Hernias.

Inguinal ultrasound (US) has a high sensitivity and specificity for the diagnosis of inguinal hernias but is often performed unnecessarily, adding cost and time to treatment. The aim of our study was to assess the rate and necessity of US before clinical examination by a hernia surgeon. Medical records of patients referred for an inguinal hernia from April through July 2017 were reviewed. These cases were analyzed for patient demographics, physical examination (PE) findings, previsit imaging, health-care system of surgeon, and case outcome. Twenty-nine per cent of patients had an inguinal US before visiting a surgeon. Sixty-three per cent of patients who underwent an US had a palpable hernia on PE, and 76 per cent had a positive PE by the surgeon. Patients without a hernia on referring provider's PE underwent US 59 per cent of the time. Inguinal USs are being ordered unnecessarily by referring providers. Physical examination by referring providers and surgeons should be the primary tool for diagnosis of an inguinal hernia.

Endovascular Coil Migration Into the Intestinal Lumen: Two Cases of Successful Nonoperative Management.

Endovascular embolization of visceral arteries is commonly performed as treatment for aneurysms, pseudoaneurysms, and emboloradiation of liver tumors; while considered relatively safe, it is not without complications. We are reporting 2 cases of coil migration into the gastrointestinal tract. Patients were successfully managed without endoscopic or surgical coil removal. Patients were followed after discharge and noted to have no further complications from their migrated coils. These cases highlight the success of expectant management for coil migration. We recommend against invasive intervention for coil removal as first-line treatment for endovascular coil migration into the intestinal tract. We urge providers to weigh the risks and benefits of coil removal, prior to invasive intervention.

Do Histopathologic Variables Affect the Reporting of Lymphovascular Invasion in Testicular Germ Cell Tumors?

OBJECTIVES: Identification of lymphovascular invasion (LVI) in testicular germ cell tumors (GCTs) is a challenging yet important aspect of cancer staging that can alter therapeutic management. Our study aimed to identify pathologic features that affect the reporting of LVI. METHODS: Pathology report and slide review of orchiectomies performed at our institution between 2007 and 2013 for testicular GCTs were performed. RESULTS: Seminomas grossed by residents had a higher rate of reported LVI compared with specimens grossed by pathology assistants (46% vs 15%). Tumor displacement artifact was more frequent in seminomas vs mixed GCTs (60% vs 38%). LVI concordance was high upon review (κ = 0.77), with displacement artifact present in all discrepancies. Tumor emboli from cases reported to have LVI had a higher frequency of tumor cohesiveness, smooth contours, and adherence to vessel walls compared with tumor emboli that were considered pseudo-LVI. Presence of fibrin and RBCs were features found at a similar frequency in emboli that were reported as LVI compared with those deemed artifactual. CONCLUSIONS: Grosser type, tumor subtype, tumor displacement artifact, and characteristics of tumor emboli are pathologic features that affect the interpretation of LVI in testicular GCTs. Pathologists should be aware of these variables to more accurately diagnose LVI.
