1/15. Cotton gauze foreign body granuloma following microvascular decompression.We describe a case of a cotton gauze foreign-body granuloma developing 2 months after microvascular decompression for trigeminal neuralgia and hemifacial spasm. This complication has not been previously described. Moreover, the patient's initial clinical and radiological findings were suggestive of an acoustic neuroma or meningioma at the time.- - - - - - - - - - ranking = 1keywords = cotton (Clic here for more details about this article) |
2/15. Silicone prosthesis prevents vertigo due to the defect at the mastoid process after mastoidectomy: a clinical report.This clinical report describes a 64-year-old woman with a bony defect in the mastoid process after mastoidectomy and who experienced vertigo on cold and windy days during winter. The patient noticed that packing a piece of paper or cotton into the defect prevented the vertigo. The patient refused surgical repair, so a silicone prosthesis was fabricated to fill the defect completely. electronystagmography confirmed the effectiveness of the prosthesis to prevent nystagmus. Although surgical repair is ideal, prosthesis repair of the defect may prove to be effective in some patients.- - - - - - - - - - ranking = 1keywords = cotton (Clic here for more details about this article) |
3/15. Gossypiboma--"a surgeon's legacy": report of a case and review of the literature.Gossypiboma (from Latin gossipium cotton and Kiswahili boma place of concealment) or retained surgical sponge is a ubiquitous medical error that is avoidable. It can cause serious morbidity and possibly even mortality. Because it is not anticipated, it is frequently misdiagnosed, and often-unnecessary radical surgical procedures are performed. It should be considered in the differential diagnosis of any postoperative case with unresolved or unusual problems.- - - - - - - - - - ranking = 1keywords = cotton (Clic here for more details about this article) |
4/15. Textiloma of the thigh presenting as a sarcoma.Textiloma is defined as a tumor composed of cotton matrix surrounded by granulomatous reaction. It occurs following operations in which surgical sponges were inadvertently left behind. We describe a case of a 59-year-old man presenting with a pathologic fracture of the proximal left femur. The results of the biopsy, unlike diagnoses suggested by radiographs, CT scan and magnetic resonance imaging revealed a textiloma of 23 years of evolution. Because of major bone loss, resection of the involved bone was performed followed by ipsilateral fibular bone graft.- - - - - - - - - - ranking = 1keywords = cotton (Clic here for more details about this article) |
5/15. Progressive visual loss due to a muslinoma--report of a case and review of the literature.Intracranial internal carotid artery (ICA) aneurysms are frequently treated either by microsurgical clipping of the aneurysm neck, by endovascular coiling of the aneurysm sac or by balloon occlusion of the parent vessel. For some broad-based aneurysms that may not be suitable for any of these options, microsurgical wrapping of the aneurysm wall with muslin or gauze rarely is applied. We report the case of a patient who suffered from a minor stroke because of arterio-arterial embolism from an intracranial ICA aneurysm. The aneurysm was treated by wrapping muslin material. After 12 months, he experienced progressive visual loss. Cranial magnetic resonance testing magnetic resonance tomography (MRT) revealed a granulomatous inflammation surrounding the site of the aneurysm and affecting optochiasmatic structures. A muslin-induced optic neuropathy is a rare but serious complication of a chronic inflammatory reaction in response to muslin or gauze used in intracranial aneurysm wrapping. If the foreign body inflammatory reaction to muslin or gauze leads to a mass formation, the term muslinoma or gauzoma is applied. Various treatment strategies include surgery, steroids and cyclophosphamide, but recovery of the vision is not predictable. As a consequence, muslin or cotton gauze should only be applied with great caution in neurovascular surgery.- - - - - - - - - - ranking = 1keywords = cotton (Clic here for more details about this article) |
6/15. Optochiasmal arachnoiditis following cotton wrapping of anterior communicating artery aneurysm treated by surgical removal of granuloma.We report the case of a 50 year old female who presented with visual disturbance due to optochiasmal arachnoiditis and foreign body granuloma 9 months after cotton wrapping for ruptured anterior communicating artery (AcomA) aneurysm. magnetic resonance imaging (MRI) revealed enhanced mass lesion around AcomA complex and hyperintense signal on optic chiasm and right optic tract by fluid-attenuated inversion recovery image. Despite the repeated steroid pulse therapy, she deteriorated and MRI showed expansion of the granulomatous lesion over 5 months. Surgical removal of foreign body granuloma resulted in marked improvement of visual disturbance as well as of the MRI findings. We conclude that the use of cotton sheet close to the optic nerve should be avoided, and that surgical removal of the granuloma would be the optimal choice especially for the patient in whom steroid therapy fails to improve clinical symptoms.- - - - - - - - - - ranking = 6keywords = cotton (Clic here for more details about this article) |
7/15. Neuropraxia of the cutaneous nerve of the cervical plexus after shoulder arthroscopy.This article presents uncommon cases of neuropraxia of the lesser occipital nerve and the greater auricular nerve after arthroscopic surgery of the shoulder in the beach-chair position under general anesthesia. The lesser occipital nerve and the greater auricular nerve are superficial ascending branches of the cervical plexus. These 2 superficial nerves may be easily vulnerable because of their superficial anatomic locations. We assumed that the severity of the neuropraxia of superficial branches of the cervical plexus was related to the degree of rotation and deviation of the head and neck, the duration of the procedure, and compression by head strap and elastic bandage used for fixing the head to the rectangular-shaped headrest of the beach-chair device. We recommend that during surgery in the beach-chair position, the auricle be protected and covered with cotton and gauze to avoid direct compression and the position of the head and neck be checked and corrected frequently. We hope for a new design of the headrest of the beach-chair device to prevent neuropraxia and to attach the head firmly and safely.- - - - - - - - - - ranking = 1keywords = cotton (Clic here for more details about this article) |
8/15. Lintene granuloma following microvascular decompression mimicking a cerebellopontine angle tumour.We describe a case of foreign body granuloma caused by lintene (cotton gauze), placed during microvascular decompression of the fifth nerve for trigeminal neuralgia. At presentation, the clinical and radiological findings were suggestive of a tumor. This is only the second case in the literature of a foreign body granuloma occurring owing to the placement of a lintene pledget during microvascular decompression.- - - - - - - - - - ranking = 1keywords = cotton (Clic here for more details about this article) |
9/15. Intraretinal gray lesions as a sign of reversible visual loss following prolonged ophthalmic artery hypoperfusion.A 49-year-old woman developed severe unilateral visual loss following carotid artery ligation for a carotid-cavernous fistula. The pathophysiology was presumed to be an ophthalmic artery steal caused by the fistula. This was confirmed when visual acuity was restored by a subsequent ligation of the ophthalmic artery, despite 2 weeks of profound visual loss and ocular ischemia. Superficial cotton-wool spots and deep gray intraretinal lesions developed in the retina during the period of ocular ischemia. We postulate that the deep intraretinal lesions are clinical manifestations of a zone of retinal microvascular watershed ischemia, and that their presence may be an important diagnostic guide to the presence of reversible ocular ischemia.- - - - - - - - - - ranking = 1keywords = cotton (Clic here for more details about this article) |
10/15. Iatrogenic microemboli of pulmonary arteries in infants.The identification of emboli of the pulmonary arterioles with foreign bodies by means of morphologic examination was made in 5 infants aged from 8 days to 5 months. Positive results of special staining procedures of foreign bodies, particularly when applying for the first time a dye Siriusrot F3B, used in the textile industry, permitted an identification of the bodies localized both intra- and extravascularly as cotton fibres. The origin of fibres, tissue reactions, and the pathogenetic significance of the emboli due to foreign bodies are discussed.- - - - - - - - - - ranking = 1keywords = cotton (Clic here for more details about this article) |
