Abstract
Pituitary apoplexy (PA) is an emergency condition caused by sudden hemorrhage or infarction and characterized by sudden sella turcica compression, intracranial hypertension and meningeal stimulation. PA usually occurs secondary to pituitary adenomas and can serve as the initial manifestation of an undiagnosed pituitary adenoma in an individual. In the present study, a case of PA following surgery for cervical stump adenocarcinoma was reported. The patient experienced an abrupt onset of headache and drowsiness on postoperative day 1 (POD1), and developed blurred vision and blepharoptosis of the left eye on POD4. Pituitary MRI confirmed the diagnosis of PA, prompting the initial administration of hydrocortisone to supplement endogenous hormones, followed by trans-sphenoidal resection. At the six-week follow-up, the patient had fully recovered, with only mild residual blurring of vision. Diagnosing PA post-surgery can be a challenging task due to its symptomatic overlap with postoperative complications. The existing literature on PA after surgery was also reviewed, including the symptoms, time of onset, imageological examination, management, potential risk factors and outcome to improve on early detection and individualized treatment in the future.

Abstract
CD44 is a ubiquitous leukocyte adhesion molecule involved in cell-cell interaction, cell adhesion, migration, homing and differentiation. CD44 can mediate the interaction between leukemic stem cells and the surrounding extracellular matrix, thereby inducing a cascade of signaling pathways to regulate their various behaviors. In this review, we focus on the impact of CD44s/CD44v as biomarkers in leukemia development and discuss the current research and prospects for CD44-related interventions in clinical application.

Gupta B, Singla D, Gupta A, Mahaseth R. Incidence and Risk Factors for Postoperative Visual Loss after Cardiac Surgical Procedures: A Systematic Review. Ann Card Anaesth 2024; 27:101-110. [PMID: 38607873 PMCID: PMC11095781 DOI: 10.4103/aca.aca_85_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 08/18/2023] [Accepted: 09/20/2023] [Indexed: 04/14/2024] Open
Abstract
ABSTRACT Postoperative visual loss (POVL) is an infrequent yet consequential complication that can follow cardiac surgical interventions. This systematic review aims to provide a comprehensive analysis of the incidence of POVL after cardiac surgery and to delineate the associated risk factors. A comprehensive search was conducted in major medical databases for relevant studies published up to September 2022. Eligible studies reporting on the incidence of POVL and identifying risk factors in patients undergoing cardiac surgery were included. Data extraction was performed independently by two reviewers. The pooled incidence rates and the identified risk factors were synthesized qualitatively. POVL after cardiac surgery has an overall incidence of 0.015%, that is, 15 cases per 100,000 cardiac surgical procedures. Risk factors for POVL include patient characteristics (advanced age, diabetes, hypertension, and preexisting ocular conditions), procedural factors (prolonged surgery duration, cardiopulmonary bypass time, and aortic cross-clamping), anesthetic considerations (hypotension, blood pressure fluctuations, and specific techniques), and postoperative complications (stroke, hypotension, and systemic hypoperfusion). Ischemic optic neuropathy (ION) is an uncommon complication, associated with factors like prolonged cardiopulmonary bypass, low hematocrit levels, excessive body weight gain, specific medications, hypothermia, anemia, raised intraocular pressure, and micro-embolization. Diabetic patients with severe postoperative anemia are at increased risk for anterior ischemic optic neuropathy (AION). Posterior ischemic optic neuropathy (PION) can occur with factors like hypertension, postoperative edema, prolonged mechanical ventilation, micro-embolization, inflammation, hemodilution, and hypothermia.While the overall incidence of POVL postcardiac surgery remains modest, its potential impact is substantial, necessitating meticulous consideration of modifiable risk factors. Notably, prolonged surgical duration, intraoperative hypotension, anemia, and reduced hematocrit levels remain salient contributors. Vigilance is indispensable to promptly detect this infrequent yet visually debilitating phenomenon in the context of postcardiac surgical care.

Abstract
Pituitary apoplexy, a rare clinical syndrome secondary to abrupt hemorrhage or infarction, complicates 2%-12% of pituitary adenomas, especially nonfunctioning tumors. Headache of sudden and severe onset is the main symptom, sometimes associated with visual disturbances or ocular palsy. Signs of meningeal irritation or altered consciousness may complicate the diagnosis. Precipitating factors (increase in intracranial pressure, arterial hypertension, major surgery, anticoagulant therapy or dynamic testing, etc) may be identified. Corticotropic deficiency with adrenal insufficiency may be life threatening if left untreated. Computed tomography or magnetic resonance imaging confirms the diagnosis by revealing a pituitary tumor with hemorrhagic and/or necrotic components. Formerly considered a neurosurgical emergency, pituitary apoplexy always used to be treated surgically. Nowadays, conservative management is increasingly used in selected patients (those without important visual acuity or field defects and with normal consciousness), because successive publications give converging evidence that a wait-and-see approach may also provide excellent outcomes in terms of oculomotor palsy, pituitary function and subsequent tumor growth. However, it must be kept in mind that studies comparing surgical approach and conservative management were retrospective and not controlled.

Abstract
Pituitary tumour apoplexy (PA) is a rare clinical syndrome that occurs as a result of acute haemorrhage and/or infarction within a frequently undiagnosed pituitary tumour. The sudden enlargement of the pituitary mass undergoing PA is responsible for a wide range of acute symptoms/signs (severe headache, visual loss, diplopia, hypopituitarism, impaired consciousness) which, together with the radiological evidence of a pituitary lesion, establish the diagnosis. The optimal care of PA requires involvement of a multidisciplinary team including endocrinologist, neurosurgeon, neuroophthalmologist and the management strategy that depends on the clinical manifestations, as well as the presence of co-morbidities. Prompt surgical decompression is initially indicated in cases with severe or progressive impairment of the visual acuity or the visual fields or with altered mental state and leads to visual and neurological recovery in most of the patients. The patients with mild, stable clinical picture (including those with isolated ocular palsies) can be managed conservatively (support of fluid and electrolyte balance and stress doses of steroids in most cases) with favourable visual and neurological outcome. Frequent reassessment is mandatory because the clinical course can be unpredictable; if progression of symptoms occurs, later elective surgery is indicated and is beneficial, especially in terms of visual outcome. The endocrinological outcome is less favourable, irrespective of the treatment option, with many patients remaining on long-term replacement therapy. Despite the above guidelines, clear proof of optimal outcomes in the form of randomised controlled trials is lacking. Regrowth of the pituitary tumour years after a PA episode is possible and patients require long-term surveillance.

Abstract
Incidence estimates for perioperative vision loss (POVL) after nonocular surgery range from 0.013% for all surgeries up to 0.2% following spine surgery. The most common neuro-ophthalmologic causes of POVL are the ischemic optic neuropathies (ION), either anterior (AION) or posterior (PION). We identified 111 case reports of AION following nonocular surgery in the literature, with most occurring after cardiac surgery, and 165 case reports of PION following nonocular surgery, with most occurring after spine surgery or radical neck dissection. There were an additional 526 cases of ION that did not specify if the diagnosis was AION or PION. We also identified 933 case reports of central retinal artery occlusion (CRAO), 33 cases of pituitary apoplexy, and 245 cases of cortical blindness following nonocular surgery. The incidence of POVL following ocular surgery appears to be much lower than that seen following nonocular surgery. We identified five cases in the literature of direct optic nerve trauma, 47 cases of AION, and five cases of PION following ocular surgery. The specific pathogenesis and risk factors underlying these neuro-ophthalmic complications remain unknown, and physicians should be alert to the potential for loss of vision in the postoperative period.

Abstract
OBJECTIVE To report a case of silent pituitary infarction that occurred after a coronary artery bypass grafting procedure and review the relevant literature. METHODS We describe a female patient with silent pituitary infarction several months after a coronary artery bypass operation and discuss her presentation, clinical findings, and laboratory evaluation. We also review similar cases in the literature. RESULTS A 73-year-old woman presented with generalized fatigue, weakness, and an elevated creatine kinase level several months after she had undergone a coronary artery bypass procedure. The findings on laboratory evaluation were consistent with hypogonadism, growth hormone deficiency, central hypothyroidism, and adrenal insufficiency. Magnetic resonance imaging of the pituitary fossa showed an empty sella turcica and no sellar enlargement. The patient had no headaches, no neuro-ophthalmologic symptoms, and no focal neurologic deficits. The presentation was slow and insidious. The patient received glucocorticoid and thyroid hormone replacement therapy, after which her clinical status improved substantially. Silent pituitary infarction after coronary artery bypass grafting has been reported previously in 3 male patients, but our current case is the first such report in a female patient. CONCLUSION Silent pituitary infarction can be a complication of a coronary artery bypass grafting procedure, with a delayed and insidious presentation.

Abstract
Pituitary tumor apoplexy is an uncommon event heralded by abrupt onset of severe headache, restriction of visual fields, deterioration of visual acuity, and weakness of ocular motility frequently coupled with clinical indications of decreased endocrine function. Hemorrhage into or necrosis of a preexisting sellar mass, usually a pituitary macroadenoma, produces an expansion of sellar contents. Compression of adjacent structures elicits the variable expression of symptoms referable to displacement of the optic nerves and chiasm and impingement of the third, fourth, and sixth cranial nerves. Damage to or destruction of the anterior pituitary leads to multiple acute and/or chronic hormone deficiencies in many patients. Medical management may be used in rare cases in which the signs and symptoms are mild and restricted to meningismus or ophthalmoplegia deemed to be stable. In patients with visual or oculomotor lability or an altered level of consciousness, expeditious surgical decompression, accomplished most commonly through a transsphenoidal approach, should be performed to save life and vision and to optimize the chance of regaining or maintaining pituitary function.

Abstract
We describe the management of a 71-yr-old man with pituitary apoplexy and severe angina pectoris who underwent treatment of an intra-cranial haemorrhage and open-heart surgery requiring anticoagulant therapy within a very short period. Subtotal removal of the pituitary tumour was undertaken under stable cardiovascular conditions. But ventricular fibrillation occurred after the neurosurgery in the intensive care unit. After the patient was defibrillated, intra-aortic balloon pumping was necessary to assist coronary artery blood flow. Twenty hours after neurosurgery, oozing from the surgical wound stopped and coronary artery bypass grafting with full heparinization was performed uneventfully.

Abstract
Pituitary apoplexy in patients with pituitary macroadenomas can occur either spontaneously or following various interventions. We present a case of a 71-year-old woman who developed third, fourth, and sixth cranial nerve palsies following administration of the four hypothalamic releasing hormones for routine preoperative testing of pituitary function. The MR examination showed interval tumor growth with impression of the floor of the third ventricle. There were also changes in signal intensity characteristics of the mass, suggestive of intratumoral bleeding. A transsphenoidal surgery with subtotal resection of the pituitary adenoma was performed. Microscopical examination revealed large areas of necrosis and blood surrounded by adenomatous tissue. Third, fourth, and sixth cranial nerve palsies completely resolved within 4 months. We conclude that MR imaging is useful in the demonstration of pituitary apoplexy following preoperative stimulation tests, but we suggest that these tests should be abandoned in patients with pituitary macroadenomas.

Abstract
Apoplexy of a previously asymptomatic pituitary macroadenoma may occur in the setting of intensive thrombolytic, antithrombotic, or anticoagulant therapy for acute myocardial infarction. Classic clinical findings may initially be nonspecific and a high index of suspicion is therefore required for early diagnosis.

Abstract
Coronary artery bypass surgery (CABS) is a common operation, which is often complicated by neurological sequelae. Disturbances of cerebral blood flow have been reported up to eight days after surgery and pituitary apoplexy has previously been reported. We report a case of hypopituitarism without pituitary apoplexy, which developed after a period of sustained arterial hypotension, during coronary artery bypass surgery.

Abstract
From the literature and our own experience, 11 cases of hemorrhage or infarction of a pituitary adenoma associated with cardiac surgery have been identified over a 13-year period. Males outnumbered females by 10 to 1. Symptoms observed were headache, lethargy, confusion, obtundation, unilateral ptosis, meiosis, and opthalmoplegia involving cranial nerves III, IV, and VI, visual field deficits, and hemiparesis. Diagnosis in most recent cases has been confirmed with computerized tomography or magnetic resonance imaging. All patients received adrenocortical steroid therapy initially. Eight patients underwent transsphenoidal hypophysectomy and all survived. One patient underwent decompression craniotomy and died. Intracranial surgery was deferred in 1 patient who survived and in another who died of a massive stroke. Residual neurological deficits were noted to be either absent, minimal, or resolving in 7 of the 9 patients who survived their initial hospitalization. While numerous mechanisms have been proposed to explain the hemorrhage and necrosis of a pituitary adenoma during heart surgery, no direct cause has been clearly identified. Surgical treatment is commonly necessary since untreated pituitary apoplexy is often fatal. Transsphenoidal hypophysectomy with decompression is the preferred method of treatment with a low perioperative mortality and fairly good long-term prognosis.

Abstract
A case of pituitary apoplexy, which presented with hyperaesthesia in the distribution of the ophthalmic division of the left trigeminal nerve and a left sixth nerve palsy following cholecystectomy, is reported. Computed tomography and magnetic resonance imaging revealed a large intrasellar mass which extended laterally into the left cavernous sinus and showed evidence of old and recent haemorrhage within the tumour. This case demonstrates that patients who present with unusual neurological symptoms involving the cranial nerves after general anaesthesia, should undergo neurological and radiological investigations.
