Two cases of pituitary apoplexy were detected in the immediate postoperative period after cardiac surgery with extracorporeal bypass. Both patients had pituitary adenomas that were asymptomatic and previously undiagnosed. One patient, a 57-year-old man, had unilateral total ophthalmoplegia and blepharoptosis with sparing of the visual system. The second patient, a 55-year-old man, had headache, marked bilateral visual loss, and ophthalmoplegia with subsequent development of a hemiparesis. Pituitary apoplexy was confirmed pathologically in both cases. Hemodynamic instability during and immediately after surgery and anticoagulation are probable precipitating factors.

Pituitary apoplexy is rare endocrine emergency which can occur due to infarction or haemorrhage of pituitary gland. This disorder most often involves a pituitary adenoma. Occasionally it may be the first manifestation of an underlying adenoma. There is conflicting data regarding which type of pituitary adenoma is prone for apoplexy. Some studies showed predominance of non-functional adenomas while some other studies showed a higher prevalence in functioning adenomas amongst which prolactinoma have the highest risk. Although pituitary apoplexy can occur without any precipitating factor in most cases, there are some well recognizable risk factors such as hypertension, medications, major surgeries, coagulopathies either primary or following medications or infection, head injury, radiation or dynamic testing of the pituitary. Patients usually present with headache, vomiting, altered sensorium, visual defect and/or endocrine dysfunction. Hemodynamic instability may be result from adrenocorticotrophic hormone deficiency. Imaging with either CT scan or MRI should be performed in suspected cases. Intravenous fluid and hydrocortisone should be administered after collection of sample for baseline hormonal evaluation. Earlier studies used to advocate urgent decompression of the lesion but more recent studies favor conservative approach for most cases with surgery reserved for those with deteriorating level of consciousness or increasing visual defect. The visual and endocrine outcomes are almost similar with either surgery or conservative management. Once the acute phase is over, patient should be re-evaluated for hormonal deficiencies.

BACKGROUND Gastrointestinal endoscopic procedures are widely used for diagnostic and therapeutic measures. Analgesia and sedation/anesthesia are inseparable parts of these studies and their related complications are inevitable. METHODS In a retrograde descriptive study in Shahid Beheshti Hospital, affiliated to Qom University of Medical Sciences, Qom, Iran from March 2013 to March 2017, we gathered information regarding common anesthesia related complications and analyzed them. RESULTS 44659 procedures were performed during the study period and records of 21342 men (47.79%) and 23317 women (52.21%) were evaluated. Hemodynamic instability (9998; 22.39%), dysrhythmia (1600; 3.58%), desaturation (608; 1.36%), prolonged apnea (34; 0.08%), aspiration (43; 0.10%), postoperative nausea and vomiting (PONV) (636; 1.42%), headache (106; 0.24%), delirium (51; 0.11%), aphasia (1; 0.00%), masseter muscle spasm (1; 0.01%), myocardial infarction (2; 0.00%), and death (5; 0.01%) were seen in the patients. CONCLUSION Sedation/anesthesia is enough safe in gastrointestinal endoscopic procedures to enhance the patients' satisfaction and cooperation. If anesthesia with spontaneous breathing and unsecure airway is selected for this purpose, vigilance of anesthesia provider will be the key element of uneventful and safe procedure.
