1/5. Carotid body tumors: the role of preoperative embolization.

    Resection of carotid body tumors (neck paragangliomas) carries inherent risks of injury to the cranial nerves and other structures as well excessive blood loss. Preoperative embolization has been used to lessen the morbidity in tumors that are larger than 2 cm in diameter. Two female patients presented for treatment with large asymptomatic carotid body tumors-one 4 cm and one 5 cm in diameter. Both patients had preoperative angiography the day before surgery that revealed the feeding arterial vessels so that successful embolization could be accomplished with gel. Success was judged by diminution of the angiographic blush. Both patients had an uneventful surgical excision the following day with the carotid body tumors being able to be resected periadventitially without damage to either the external or internal carotid artery. The cranial nerves were preserved in both patients and blood loss was only 200 cc in both cases. We conclude that preoperative embolization is an important adjunct in treating patients with large carotid body tumors. The surgical exploration proceeds much smoother, the blood loss is minimal, and patients have minimal morbidity.

2/5. New approach to preoperative vascular exclusion for carotid body tumor.

    We report a new approach to preoperative vascular exclusion of a carotid body tumor. Before surgery, covered stents were placed in the external carotid artery, resulting in vascular exclusion of the tumor. Subsequent surgical excision was uneventful, with operative blood loss less than 200 mL and no neurologic complications postoperatively. This technique deserves further consideration as a reasonable alternative to conventional embolization.

3/5. Direct percutaneous embolization of a carotid body tumor with n-butyl cyanoacrylate: an alternative method to endovascular embolization.

    We report ultrasound-guided direct percutaneous injection of n-butyl cyanoacrylate for preoperative embolization of carotid body tumor in a 50-year-old patient. Angiographic road map assistance was used for protection of parent arteries during the injection. After embolization, complete devascularization of the tumor was achieved without complications. The tumor was removed surgically with minimal blood loss. This procedure is effective and promising for preoperative embolization of carotid body tumors.

4/5. Embolization: an adjunctive measure for removal of carotid body tumors.

    Small carotid body tumors that do not encircle the internal carotid artery are excised with relative ease and minimal risk by the conventional subadventicial approach. Large carotid body tumors frequently encircle the internal and external carotid arteries, and extensive bleeding often complicates the resection, increasing the risk of carotid artery rupture and damage to major cranial nerves. Recent improvements in surgical techniques and selective embolization have lessened the risks of surgical excision, decreased the blood loss, and diminished the time required for resection. Experiences in the resection of carotid tumors with and without embolization are compared. Early resection of carotid body tumors, before involvement of the internal carotid artery and carotid bulb, is advocated.

5/5. Preoperative embolization for paraganglioma.

    We have applied a new method of preoperative embolization to an intravagal and to carotid body paraganglioma, using estrogen dissolved in absolute alcohol and polyvinyl alcohol particles, which diffusely embolizes vessels from capillaries to main feeders. Total resection of the tumors after embolization was successively performed without postoperative complications; total blood loss was 205 and 130 ml, respectively, and the surgical time was approximately 3 hours in both cases. The technique, characteristics, and advantages of this method are discussed.
