Vascular Tumors of the Neck in Adults: 10-Year Experience in a Tertiary Center.

INTRODUCTION: The diagnosis and management of vascular lesions of the neck is a challenging task that requires a multidisciplinary approach. This retrospective study assesses the single center experience of vascular tumors of the neck. MATERIALS AND METHODS: Patients diagnosed with a vascular tumor and/or a mass in close proximity to the carotid artery were identified from our records over a 10-year period. The demographic characteristics, clinical features, surgical approach, and outcomes were reviewed. RESULTS: Surgical excision of 17 vascular lesions were performed in 16 patients with a mean age of 51.56 ± 17.35 years at the time of operation. Intra- and/or postoperative clinical and histological assessment revealed unilateral glomus caroticum (N = 11), glomus vagale (N = 2), bilateral glomus caroticum (N = 1), cavernous hemangioma (N = 1), and carotid sheath tumor (N = 1). In three patients, internal carotid artery, common carotid artery and vagal nerve were sacrificed to facilitate complete tumor excision. During the follow-up period, no tumor recurrences were observed, and the morbidity and mortality were minimal. CONCLUSION: Preoperative evaluation concerning the size, extent, and anatomical relationships of the tumor thoroughly should be investigated. Multidisciplinary approach involving vascular surgery, otolaryngology, and radiology is preferred to treat these patients for better outcomes. Preoperative embolization in selected cases may decrease estimated blood loss and operative time.

Endovascular Repair of Iliac Artery Aneurysms: A Single Center Experience in 10-Years.

OBJECTIVES: Isolated iliac artery aneurysms (IAAs) are rare, but nonetheless life-threatening when ruptured. The endovascular approach has taken over open repairs in time. The reported data is constituted of a retrospective series. We reviewed our 10-year-long experience with elective endovascular treatment of iliac aneurysms. METHODS: Data regarding 22 patients with 24 IAAs treated with endovascular stent grafting between 2005 and 2015 were reviewed. RESULTS: Twenty-two patients (aged 68.4 ± 9.6 years, range 50-82) with 24 unilateral or bilateral iliac aneurysms were treated. Twenty patients (91%) were male. Two patients with unilateral IAA had prior abdominal aortic aneurysm (AAA) surgical repair. The mean aneurysm diameter was 4.8 ± 2.1 (3.8 to 7.1) mm. Procedural success rate was 100%, only one patient with an iliovenous fistula had periprocedural type II endoleak. Internal iliac artery coil occlusion was applied in 16 of 24 procedures (66%). Thirty-day mortality included one patient (4%). CONCLUSION: Endovascular repair is the preferred approach for isolated IAAs. Because of the retrospective nature of data sets, larger cohorts are necessary for better definition of morbidity and mortality rates.

Staged or Combined Approach for Carotid Endarterectomy in Patients Undergoing Coronary Artery Bypass Grafting: A 5-Year-Long Experience.

BACKGROUND: Optimal surgical approach for patients with hemodynamically significant carotid and coronary disease remains controversial. We analyzed our 5-year experience and compared early and long-term outcome following staged and combined carotid and coronary artery bypass. METHODS: 312 consecutive patients undergoing carotid endarterectomy and coronary artery bypass between 2008 and 2013 were prospectively enrolled in the study. Patients were scheduled for a staged (carotid endarterectomy followed by coronary artery bypass within 1 week) procedure (Group S) unless they were unstable in terms of cardiac status (were deemed to a combined procedure; Group C). All patient data including demographics, risk factors, immediate perioperative events, 30-day, and long-term outcome were prospectively recorded and then analyzed. Groups S and C were compared for pre- and perioperative data as well as immediate, 30-day, and long-term survival. A P value less than .05 was considered significant. Survival analysis was made using Kaplan-Meier method and log-rank test. RESULTS: Group S included 204 patients and Group C included 108 patients. Preoperative demographics and clinical data were similar in the two groups except that preoperative cerebrovascular events were more common in Group C (31.7% versus 22.22%, P = .036) and bilateral carotid disease was more common in Group S. The EuroSCORE was higher in Group C (2.91 versus 2.65, P = .013). Carotid surgery techniques were similar; intraluminal shunting was more frequent in group C than group S (33.33% versus 9.88%, P = .001). Additional cardiac procedures in addition to coronary surgery was predominant in Group C. 30-day neurological adverse event rates, ICU, and hospital stay were significantly higher in Group C. The 30-day mortality was also sigficantly higher in Group C (1.96% versus 4.62%, P = .001). CONCLUSION: Staged and combined surgical approaches yield comparable outcomes. A staged approach may provide a more favorable neurological outcome with significantly reduced need for intraluminal shunting. Long-term outcome is, however, similar.

Debranching solutions in endografting for complex thoracic aortic dissections.

BACKGROUND: Conventional surgical repair of thoracic aortic dissections is a challenge due to mortality and morbidity risks. OBJECTIVES: We analyzed our experience in hybrid aortic arch repair for complex dissections of the aortic arch. METHODS: Between 2009 and 2013, 18 patients (the mean age of 67 ± 8 years-old) underwent hybrid aortic arch repair. The procedural strategy was determined on the individual patient. RESULTS: Thirteen patients had type I repair using trifurcation and another patient with bifurcation graft. Two patients had type II repair with replacement of the ascending aorta. Two patients received extra-anatomic bypass grafting to left carotid artery allowing covering of zone 1. Stent graft deployment rate was 100%. No patients experienced stroke. One patient with total debranching of the aortic arch following an acute dissection of the proximal arch expired 3 months after TEVAR due to heart failure. There were no early to midterm endoleaks. The median follow-up was 20 ± 8 months with patency rate of 100%. CONCLUSION: Various debranching solutions for different complex scenarios of the aortic arch serve as less invasive procedures than conventional open surgery enabling safe and effective treatment of this highly selected subgroup of patients with complex aortic pathologies.

Fundamentos: O reparo cirúrgico convencional de dissecção da aorta torácica é um desafio devido aos riscos de mortalidade e morbidade. Objetivos: Analisamos nossa experiência no reparo híbrido do arco aórtico em dissecções complexas do arco aórtico. Métodos: Entre os anos de 2009 e 2013, 18 pacientes (idade média de 67 ± 8 anos de idade) foram submetidos ao reparo híbrido do arco aórtico. A estratégia de procedimento foi determinada individualmente para cada paciente. Resultados: Treze pacientes fizeram o reparo tipo I utilizando enxerto trifurcado; outro paciente utilizou um enxerto bifurcado. Dois pacientes fizeram o reparo tipo II com substituição da aorta ascendente. Dois pacientes receberam desvios extra-anatômicos de enxertia pela artéria carótida esquerda, permitindo a cobertura da zona 1. A taxa de implantação do stent foi de 100%. Nenhum paciente apresentou acidente vascular cerebral. Um paciente com desramificação total do arco aórtico após dissecção aguda do arco proximal faleceu 3 meses depois de realizar o reparo endovascular da aorta torácica (TEVAR), por insuficiência cardíaca. Não houve endoleak precoce ou a médio prazo. A média de acompanhamento foi de 20 ± 8 meses, com taxa de patência de 100%. Conclusão: Diversas soluções de desramificação, utilizadas em diferentes cenários complexos do arco aórtico, são procedimentos menos invasivos que a cirurgia aberta convencional e permitem o tratamento seguro e eficaz deste subgrupo, altamente selecionado de pacientes com patologias complexas da aorta. .
