Complex Aortic, Visceral and Renal Arteries Reconstruction with a Four-Branch Dacron Graft for Middle Aortic Syndrome Secondary to Takayasu's Arteritis.

The middle aortic syndrome (MAS) is an uncommon clinical expression as a result of isolated stenosis or complete occlusion of the descending thoracic and/or abdominal aorta; Takayasu's arteritis (TA) is a rare vasculitis and a recognized etiology of MAS. We herein present the case of a 52-year-old woman with refractory renovascular hypertension and progressive bilateral lower extremity claudication; she had known history of TA. A computed tomography angiography demonstrated an aortic occlusive lesion compromising the origin of the celiac trunk, superior mesenteric, and bilateral renal arteries. The patient underwent a complex aortic reconstruction with visceral and renal vessels revascularization utilizing a back-table hand-crafted 4-branch Dacron graft through a left thoracoabdominal approach. The patient recovered uneventfully and was discharged on postoperative day 5, and at 36 months from her surgery, she remains symptoms-free and without antihypertensive agents.

Viabahn-assisted sutureless anastomosis (VASA) repair of a complex internal carotid artery aneurysm.

Extracranial carotid artery aneurysms (CAAs) are extremely rare and often require surgical intervention to avoid complications such as local compression symptoms and thrombo-embolization. We present the case of a 63-year-old man with a history of hypertension, meningioma, and an incidental finding of a right saccular internal carotid artery aneurysm at the base of the skull. He underwent open surgical repair; nonetheless, end-to-end anastomosis was not feasible. As bailout, the internal carotid artery was successfully reconstructed with a novel Viabahn-assisted sutureless anastomosis technique (GORE, Viabahn). Postoperative clinical assessment revealed no complications, postoperative computed tomography angiography revealed a patent reconstruction, and the patient was discharged home uneventfully with 1-year clinical and computed tomography angiography follow-up without remarks. Hybrid procedure is a viable option for technically challenging carotid anastomoses near the skull base.

Complex and Successful Management of a Symptomatic Isolated Abdominal Aortic Aneurysm in a Pregnant Woman with Marfan Syndrome.

Aortopathies associated to Marfan syndrome (MFS) are important causes of maternal death during pregnancy. We present a 27-year-old and 24-week pregnant MFS woman who arrived to the emergency department with increasing abdominal pain; an obstetric ultrasound showed an Abdominal Aortic Aneurysm (AAA), a multislice computed tomography angiography (CTA) confirmed and demonstrated a 7.3 centimeter (cm) infrarenal AAA without evidence of dissection. A multidisciplinary committee determined that an open repair would lead to a significantly high maternal-fetal morbidity and mortality. Although endovascular repair (EVAR) in MFS patients remains controversial, an urgent bridge therapy was considered to be the best option. She was transferred to the angiography suite for EVAR to prevent AAA rupture and ensure a satisfactory pregnancy. The patient and fetus presented no complications during the procedure and were discharged 3 days later. She continued her pregnancy without eventualities and an elective C-section was performed on week 36. A CTA imaging at 12 months revealed type 1A and 3 endoleaks, we decided to perform endograft explant and a definitive open repair, there were no complications during the procedure, the patient is currently asymptomatic. Our case illustrates a complex decision and management that successfully avoid morbidity and mortality of a MFS mother and her product; additionally, this experience reinforces the need for lifelong and close surveillance in these patients.

Subclavian-Brachial Bypass for Chronic Limb Threatening Ischemia Associated with an Old Motorcycle Accident.

Chronic limb-threatening ischemia is rarely associated with previous traumatic injury. We present a case of a 28-year-old male with progressive digit ulcers, a weak pulse, cyanosis, and a cold limb. Eight months prior, he had a motorcycle accident resulting in a right clavicle fracture and brachial plexus injury. Computed tomography angiography revealed occlusion of the right subclavian artery near a surgically implanted reduction plate. The patient underwent an open subclavian-brachial bypass with a reversed saphenous vein graft. His postoperative recovery was uneventful. After 3 months, he had a euthermic right hand with a palpable pulse and his ulcers had completely healed. This case reinforces the need for patients with a neurological deficit in the upper extremity caused by blunt trauma to undergo thorough vascular examination to identify potential arterial injury and compromised perfusion.

Surgical Management of a Type II Extracranial Internal Carotid Aneurysm near to the Skull Base.

True aneurysmal disease in the carotid arteries is very uncommon, but individuals with this pathology face the grave risk of thromboembolism, which may consequently lead to cerebrovascular accidents. Clinical knowledge remains relatively limited owing to its rarity. We present the case of a 41-year-old obese female with a type II right extracranial internal carotid artery aneurysm incidentally found during imaging work-up. She underwent open surgical reconstruction with an autologous interposition graft from the common carotid artery to the internal carotid artery at the base level of the skull. Her postoperative period was uneventful, and the patient was discharged on postoperative day five with aspirin. At 12 months of follow-up, the patient remained symptom-free without complications.

Favorable Conservative Management of a Rare Primary Aortitis Secondary to Listeria Monocytogenes: Case Report and Review of the Literature.

Primary aortitis (PA) secondary to Listeria monocytogenes is extremely rare with only a few cases reported in the literature. Presently, there is no consensus concerning the best treatment when no complications are found in the thoracic computed tomography (CT) imaging. This report illustrates the clinical presentation and favorable clinical course of a rare case of PA secondary to Listeria monocytogenes in an 82-year-old diabetic woman, successfully treated with conservative management with 18 months of follow up. Included in this article, we additionally present a review of the literature of this uncommon etiology of infectious aortitis.

Comparison of axillary-atrial and axillary-iliac arteriovenous grafts for hemodialysis access creation.

OBJECTIVE: The aim of this study was to compare two complex vascular access techniques that utilize the axillary artery as inflow and accesses were created with early cannulation grafts: the axillary-atrial arteriovenous graft versus axillary-iliac arteriovenous graft. METHODS: This is a retrospective study of end-stage renal disease patients with occluded intrathoracic central veins that underwent complex hemodialysis access creation in our institution after failed endovascular recanalization attempts. Patients' demographics, comorbidities, number and types of previous accesses, intraoperative variables, and clinical outcomes were collected and compared. RESULTS: Four patients underwent axillary-atrial arteriovenous graft creation with Flixene™ (Atrium™, Hudson, NH, USA) grafts, through a midline sternotomy to expose the right atrium; all were successfully implanted and used for hemodialysis within the first 72 h; one patient developed a pseudoaneurysm in the mid-graft portion, requiring surgical repair, and it is currently functional. Eight axillary-iliac arteriovenous grafts were created; all grafts were patent and were utilized within 96 h after placement. At 6 months of follow-up period, five (62 %) of our patients underwent graft thrombectomy, one (12 %) balloon angioplasty at the vein anastomosis secondary to stenosis, and two (25 %) grafts were removed due to infectious complications. Axillary-atrial arteriovenous graft and axillary-iliac arteriovenous graft primary patency rates at 6 months were 75% and 48%, respectively; 6-month secondary patency of the axillary-atrial arteriovenous graft compares favorably against that of axillary-iliac arteriovenous graft (100% vs 75%, respectively). CONCLUSION: Despite the invasiveness, direct atrial outflow procedures remain a valid alternative in carefully selected patients with adequate cardiopulmonary reserve.

A case report of a concomitant total thyroidectomy and carotid body tumor resection in a 43 year old female.

INTRODUCTION: Carotid body tumors (CBT) are rare neoplasms with relatively; due to their malignant potential, the indicated treatment is surgical resection. There have been described some associations of carotid body tumors with other neoplasms, however, the concomitant presentation of CBT with multinodular goiter is rarely encountered. PRESENTATION OF CASE: We herein present the case of a 43-year old woman with the aforementioned association. As a part of the diagnostic evaluation, an ultrasound was performed, revealing both conditions simultaneously. The surgery took place with the aim of resecting both lesions during the same intervention. The patient was discharged without complications. DISCUSSION: The concomitant presentation of goiter and carotid body tumor is rarely reported but an extended Kocher incision could be enough to an adequate exposure and same surgical procedure resection. CONCLUSION: This case reinforce the concomitant assessment in two different pathologies. Although there is one case reported before, this case lead to improvement in the treatment of these patients.

Left Common Femoral to Right Common Iliac Venous Bypass Through a Retroperitoneal Exposure.

The endovascular recanalization of the iliocaval system has replaced venous surgical reconstructions as the primary treatment option in severe post-thrombotic syndrome (PTS). We herein present a 51-year-old female with previous deep venous thrombosis, complicated with PTS with a large and complex circumferential calf ulcer measuring 25 cm of length in the left lower extremity. Venogram revealed a complete and extensive occlusion in the left iliofemoral system. A surgical bypass from the left common femoral vein to the right common iliac vein was performed. Patient recovered well and after 12 months postoperation her large wound is healing favorably with a clean and well granulated bed. Iliofemoral venous bypass is a feasible treatment for non-healing ulcer of lower extremity.
