Abstract

Abstract BACKGROUND Craniopharyngioma (CP), although slow growing and histologically benign, carries considerable morbidity, particularly in the postoperative period: hypothalamus-pituitary dysfunction and electrolyte disorders represent common complications. Moreover, in these patients, the increased risk of deep venous thrombosis (DVT) and the possible development of fusiform intracranial aneurysms are well known. However, data are still poor, especially in the pediatric population. The aim of our study was to describe the occurrence and timing of DVT and other vascular alterations in neurosurgical operated CP patients and to evaluate the role of predisposing factors in the development of post-surgical and late vascular events. MATERIAL AND METHODS This was a single-center, retrospective study. We investigated 19 patients (11 males, 8 females, mean age 10.47±4.29) diagnosed with CP, who had been subjected to neurosurgery between December 2016 and August 2022 in Meyer Children’s Hospital IRCCS in Florence. Demographic and clinical characteristics and surgical data were recorded for each participant. RESULTS Five patients (26.3%, 3 females, 2 males, median age 15 years) presented vascular events, all during sodium imbalance. Calcium at lower limits was detected in four of them. Three DVT (two with associated pulmonary embolism, including one female patient’s death) developed after surgery, more frequently at 7-10 days (two patients were central catheter carriers, one obese patient showed hypercholesterolemia and hypertriglyceridemia). In a patient in hyponatraemic state a vascular parietal alteration compatible with pseudoaneurysm was described soon after neurosurgery, requiring vascular stenting and prolonged intensive care. Superficial vein thrombophlebitis was a late complication in an overweight female patient on estrogenic replacement therapy. CONCLUSION Patients with CP undergoing neurosurgical brain tumor resection are at a higher risk of developing DVT and vascular alterations, thus careful follow-up should be done in these patients. In our study, we found that the phase of transition from central diabetes insipidus (CDI) to syndrome of inappropriate antidiuretic hormone secretion (SIADH) is probably a significative time for developing this complication; so, we recommend careful monitoring of symptoms suggestive of vascular events in CP operated patients. However, we suggest the execution of a deep vein ultrasound examination in the post-neurosurgical two-four weeks for an early diagnosis of this problem for reducing the risk of severe complications.
