[The use of platelet gel for repair of a cerebrospinal fluid fistula of the skull base (a case report and literature review)]. / Primenenie trombotsitarnogo gelia dlia plastiki likvornoi fistuly osnovaniia cherepa (sluchai iz praktiki i obzor literatury).

Nasal liquorrhea is a serious problem in surgery of skull base tumors, which is associated with a high risk of purulent-septic complications. This paper presents a case of successful repair of a cerebrospinal fluid fistula with an autologous platelet gel in the postoperative period after removal of meningioma of the anterior cranial fossa base, which was accompanied by a purulent-inflammatory complication in the surgical wound area.

[Complications after endoscopic endonasal transsphenoidal removal of pituitary adenomas]. / Oslozhneniia posle éndoskopicheskogo éndonazal'nogo transsfenoidal'nogo udaleniia adenom gipofiza.

The use of endoscopic technique has significantly extended the indications for surgery using the transsphenoidal approach. Currently, more than 90% of pituitary adenomas are operated on transsphenoidally. Transnasal removal of giant pituitary adenomas has become possible. Transition to the endoscopic endonasal approach in removal of pituitary adenomas changed the rate and structure of postoperative complications. We analyzed potential complications after endoscopic endonasal transsphenoidal removal of pituitary adenomas. These include complications of the approach itself (nasal bleeding, perforation of the nasal septum, impaired olfactory function, atrophic rhinitis, synechiae, mucoperiosteal flap necrosis, and external nasal deformities), infectious complications (meningitis, intracranial abscesses), cerebral circulation disorder (subarachnoid hemorrhage, cerebral vasospasm, injury to large vessels, intracranial hematomas), neuro-ophthalmological complications (visual and oculomotor disorders), endocrine (hypopituitarism, diabetes insipidus, hyponatremia) and somatic complications, and nasal liquorrhea. In conclusion, it should be noted that despite continuous improvement of the technique for endoscopic endonasal removal of pituitary adenomas, there is a risk of serious complications, which necessitates the development of techniques for prevention of these complications.
