Carotid Body Tumors

OBJECTIVECarotid body tumors (CBTs), extraadrenal paragangliomas, are extremely rare neoplasms in children that often require multimodal surgical treatment, including preoperative anesthesia workup, embolization, and resection. With only a few cases reported in the pediatric literature, treatment paradigms and surgical morbidity are loosely defined, especially when carotid artery infiltration is noted. Here, the authors report two cases of pediatric CBT and provide the results of a systematic review of the literature.METHODSThe study was divided into two sections. First, the authors conducted a retrospective review of our series of pediatric CBT patients and screened for patients with evidence of a CBT over the last 10 years (2007–2017) at a single tertiary referral pediatric hospital. Second, they conducted a systematic review, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, of all reported cases of pediatric CBTs to determine the characteristics (tumor size, vascularity, symptomatology), treatment paradigms, and complications.RESULTSIn the systematic review (n = 21 patients [includes 19 cases found in the literature and 2 from the authors’ series]), the mean age at diagnosis was 11.8 years. The most common presenting symptoms were palpable neck mass (62%), cranial nerve palsies (33%), cough or dysphagia (14%), and neck pain (19%). Metastasis occurred only in 5% of patients, and 19% of cases were recurrent lesions. Only 10% of patients presented with elevated catecholamines and associated sympathetic involvement. Preoperative embolization was utilized in 24% of patients (external carotid artery in 4 and external carotid artery and vertebral artery in 1). Cranial nerve palsies (cranial nerve VII [n = 1], IX [n = 1], X [n = 4], XI [n = 1], and XII [n = 3]) were the most common cause of surgical morbidity (33% of cases). The patients in the authors’ illustrative cases underwent preoperative embolization and balloon test occlusion followed by resection, and both patients suffered from transient Horner’s syndrome after embolization.CONCLUSIONSSurgical management of CBTs requires an extensive preoperative workup, anesthesia, and multimodal surgical management. Due to a potentially high rate of surgical morbidity and vascularity, balloon test occlusion with embolization may be necessary in select patients prior to resection. Careful thorough preoperative counseling is vital to preparing families for the intensive management of these children.

Abstract This case is a 66-yr-old woman with a 2-mo history of left-sided tinnitus. Workup with magnetic resonance angiography showed early opacification of the left sigmoid sinus and internal jugular vein as well as asymmetric and abundant opacification of the left external carotid artery branches, suspicious for a dural arteriovenous fistula (dAVF). Diagnosis was confirmed with cerebral angiography, consistent with a left-sided Cognard type I dAVF.1 Initial treatment attempt was made with transarterial 6% ethylene-vinyl alcohol copolymer (Onyx 18) embolization of feeders from the occipital and middle meningeal arteries. However, embolization was not curative and there was a recurrence of a highly bothersome tinnitus 3 wk following treatment. Angiography redemonstrated the transverse sinus dAVF with new recruitment arising from several feeders, including the left external carotid artery, middle meningeal artery, and superficial temporal artery, now Cognard type IIa. Definitive treatment through a transvenous coil embolization provided permanent obliteration of the fistula without recrudescence of symptoms on follow-up. In this video, the authors discuss the nuances of treating a dAVF via a transvenous embolization. Patient consent was given prior to the procedure, and consent and approval for this operative video were waived because of the retrospective nature of this manuscript and the anonymized video material.

Abstract Cerebral revascularization is the treatment of choice for select complex intracranial aneurysms unamenable to traditional approaches.1 Complex middle cerebral artery (MCA) bifurcation aneurysms can include the origins of 1 or both M2 branches and may benefit from a revascularization strategy.2,3 A novel 3-vessel anastomosis technique combining side-to-side and end-to-side anastomoses, allowing for bihemispheric anterior cerebral artery revascularization, was recently reported.4  This 2-dimensional operative video presents the case of a 73-yr-old woman who presented as a Hunt-Hess grade 4 subarachnoid hemorrhage due to the rupture of a large right MCA bifurcation aneurysm. The aneurysm incorporated the origins of the frontal and temporal M2 branches and was deemed unfavorable for endovascular treatment. A strategy using a high-flow bypass from the external carotid artery to the MCA with a saphenous vein (SV) graft was planned to revascularize both M2 branches simultaneously, followed by clip-trapping of the aneurysm. Intraoperatively, the back walls of both M2 segments distal to the aneurysm were connected with a standard running suture, and the SV graft was then attached to the side-to-side construct in an end-to-side fashion. Catheter angiograms on postoperative days 1 and 6 demonstrated sustained patency of the anastomosis and good filling through the bypass. The patient's clinical course was complicated by vasospasm-related right MCA territory strokes, resulting in left-sided weakness, which significantly improved upon 3-mo follow-up with no new ischemia.  The patient consented for inclusion in a prospective Institutional Review Board (IRB)-approved database from which this IRB-approved retrospective report was created.

Abstract Objective: Access to the high cervical internal carotid artery (ICA) is technically challenging for the treatment of lesions in and around this region. The aims of this study were to analyze the efficacy of approaching the high cervical ICA through the retromandibular fossa and to compare preauricular and postauricular incisions. In addition, the relevant neural and vascular structures of this region are demonstrated in cadaveric dissections. Methods: The retromandibular fossa approach was performed in four arterial and venous latex-injected cadaveric heads and necks (eight sides) via preauricular and postauricular incisions. This approach included three steps: 1) sternocleidomastoid muscle dissection; 2) transparotid dissection; and 3) removal of the styloid apparatus and opening of the retromandibular fossa to expose the cervical ICA with the internal jugular vein along with Cranial Nerves X, XI, and XII. Results: The posterior belly of the digastric muscle and the styloid muscles were the main obstacles to reaching the high cervical ICA. The high cervical ICA was successfully exposed through the retromandibular fossa in all specimens. In all specimens, the cervical ICA exhibited an S-shaped curve in the retromandibular fossa. The external carotid artery was located more superficially than the ICA in all specimens. The average length of the ICA in the retromandibular fossa was 6.8 cm. Conclusion: The entire cervical ICA can be exposed via the retromandibular fossa approach without neural and vascular injury by use of meticulous dissection and good anatomic knowledge. Mandibulotomy is not necessary for adequate visualization of the high cervical ICA.
