Flow Reduction–Aided Thrombin Injection for Complex Femoral Pseudoaneurysms: Case Series and Review of the Literature

Nandakumar Menon, Charles B. Drucker, Abhishek Bhardwaj, Richa Kalsi, more

Annals of Vascular Surgery > 2018 > 46 > C > 367.e1-367.e6

Peripheral pseudoaneurysms are a known complication of vascular access procedures. Complex lesions—those with short, wide necks or other complex arrangements—would conventionally require open repair, but we believe that even these lesions could be managed with an endovascular approach.Four patients with complex pseudoaneurysms were offered an open repair or thrombin injection with the use of flow-reducing...

Donald G. Harris, Anthony Herrera, Charles B. Drucker, Richa Kalsi, more

Journal of Vascular Surgery > 2017 > 66 > 5 > 1511-1517

The paradigm of acute care surgery has revolutionized nonelective general surgery. Similarly, nonelective vascular surgery may benefit from specific management and resource capabilities. To establish the burden and scope of vascular acute care surgery, we analyzed the characteristics and outcomes of patients hospitalized for vascular surgical procedures in Maryland.A retrospective analysis of a statewide...

Functional status predicts major complications and death after endovascular repair of abdominal aortic aneurysms

Donald G. Harris, Ilynn Bulatao, Connor P. Oates, Richa Kalsi, more

Journal of Vascular Surgery > 2017 > 66 > 3 > 743-750

Endovascular aneurysm repair (EVAR) is considered a lower risk option for treating abdominal aortic aneurysms and is of particular utility in patients with poor functional status who may be poor candidates for open repair. However, the specific contribution of preoperative functional status to EVAR outcomes remains poorly defined. We hypothesized that impaired functional status, based simply on the...

Management and outcomes of carotid artery extension of aortic dissections

Adriana Laser, Charles B. Drucker, Donald G. Harris, Tanya Flohr, more

Journal of Vascular Surgery > 2017 > 66 > 2 > 445-453

Aortic dissection (AD) is the most common aortic catastrophe. Carotid artery dissection due to extension of AD (CAEAD) is one severe complication of this condition. Despite years of refinement in the techniques for repair of AD, the optimal management strategy for CAEAD remains yet to be described. We hypothesized that CAEAD eventually resolves on antiplatelet therapy with a low but not insignificant...

Thoracic Endovascular Repair of Blunt Thoracic Aortic Injury in the Setting of an Aberrant Right Subclavian Artery

Donald G. Harris, Michael E. Huffner, Luqman Croal-Abrahams, Laura DiChiacchio, more

Annals of Vascular Surgery > 2017 > 42 > C > 302.e15-302.e20

Blunt thoracic aortic injury (BTAI) in a patient with an aberrant right subclavian artery (ARSA) presents unique challenges for patient management and aortic repair. Specific considerations include the need to treat coincidental ARSA, subclavian revascularization, and ARSA exclusion. Despite the rise of endovascular repair as the primary modality for aortic repair for BTAI, reports of this technique...

Chronic Type B Aortic Dissection: Endovascular and Hybrid Aortic Management

Ali Khalifeh, Nandakumar Menon, Richa Kalsi, Scarlett Hao, more

Current Surgery Reports > 2017 > 5 > 1 > 1-11

Purpose of Review Chronic and subacute type B aortic dissection (TBAD) management has advanced drastically over the past decade. We review the major progress reported in the scientific literature. Recent Findings Since early twenty first century, endovascular aortic repair has been on the rise for management of chronic and subacute TBAD. The technique has shown a mortality benefit in comparison...

Percutaneous Treatment of Multiple Recurrent Thromboembolization from a Descending Thoracic Aortic Intimal Sarcoma

Angelina S. June, Donald G. Harris, Christine Yoo, Danon Garrido, more

Annals of Vascular Surgery > 2017 > 38 > C > 321.e5-321.e8

Aortic intimal sarcomas are rare tumors that may result in distal embolic ischemia. Here, we present a patient who presented with crescendo lower extremity and mesenteric ischemic events from malignant macroembolism. Management with percutaneous pharmacomechanical thromboembolectomy enabled restoration of distal perfusion and minimally invasive collection of tumor sample to confirm the suspected diagnosis...

Repair of ruptured abdominal aortic aneurysm after cardiac arrest

Donald G. Harris, Danon Garrido, Connor P. Oates, Richa Kalsi, more

Journal of Vascular Surgery > 2016 > 64 > 5 > 1497-1502

Cardiac arrest in patients with ruptured abdominal aortic aneurysm (rAAA) is not uncommon and associated with significantly increased mortality. Although it has been suggested as a contraindication to aortic repair, the prognostic implications of preoperative cardiac arrest in the face of rAAA are controversial. The purpose of this structured review is to analyze the reported outcomes of patients...

Ethyl pyruvate modulates delayed paralysis following thoracic aortic ischemia reperfusion in mice

Bao-Ngoc Nguyen, Hassan Albadawi, Rahmi Oklu, Robert S. Crawford, more

Journal of Vascular Surgery > 2016 > 64 > 5 > 1433-1443

Delayed paralysis is an unpredictable problem for patients undergoing complex repair of the thoracic/thoracoabdominal aorta. These experiments were designed to determine whether ethyl pyruvate (EP), a potent anti-inflammatory and antioxidant agent, might ameliorate delayed paralysis following thoracic aortic ischemia reperfusion (TAR).C57BL6 mice were subjected to 5 minutes of thoracic aortic ischemia...

Nonoperative Management of Traumatic Aortic Pseudoaneurysms

Donald G. Harris, Joseph Rabin, Abhishek Bhardwaj, Angelina S. June, more

Annals of Vascular Surgery > 2016 > 35 > C > 75-81

Current blunt thoracic aortic injury (BTAI) guidelines recommend early repair of traumatic pseudoaneurysms (PSAs) due to risk for subsequent aortic rupture. Recent analyses indicate that early repair is required only in the setting of high-risk features, while delayed repair is safe and associated with lower morbidity and mortality in appropriately selected patients. To evaluate the appropriate indications...

Evolution of lesion-specific management of blunt thoracic aortic injury

Donald G. Harris, Joseph Rabin, Benjamin W. Starnes, Ali Khoynezhad, more

Journal of Vascular Surgery > 2016 > 64 > 2 > 500-505

Developments in diagnosis and treatment have transformed the management of blunt thoracic aortic injuries (BTAIs). For patients in stable condition, treatment practice has shifted from early open repair to nonoperative management for low-grade lesions and routine delayed endovascular repair for more significant injuries. However, effective therapy depends on accurate staging of injury grade and stability...

Identification and reduction of image artifacts in non–contrast‐enhanced velocity‐selective peripheral angiography at 3T

Taehoon Shin, Qin Qin, Jang‐Yeon Park, Robert S. Crawford, more

Magnetic Resonance in Medicine > 76 > 2 > 466 - 477

PurposeTo identify and reduce image artifacts in non–contrast‐enhanced velocity‐selective (VS) magnetization‐prepared peripheral MR angiography (MRA) at 3T. MethodsTo avoid signal loss in the arteries, double and quadruple refocused VS excitation pulse sequences were designed that were robust to a wide range of B₀ and B₁ offset. To suppress stripe artifact and background signal variation, we successively...

Quality of Life after Thoraco-Abdominal Aortic Aneurysm Repair

Robert S. Crawford, Richard P. Cambria

Thoraco-Abdominal Aorta > Specific Problems > 595-603

For thoraco-abdominal aortic aneurysm (TAAA) repair, the focus on traditional perioperative outcomes has expanded to include investigations on quality of life. Additional impetus for such data comes from increased public awareness about the availability of healthcare resources and also from the introduction of new, less-invasive endovascular alternatives to TAAA repair. Although the amount of data...
