Mu C, Song Z, Yu S. Delayed epistaxis after endoscopic transnasal pituitary tumor resection: clinical characteristics, risk factors, treatment and prevention. World J Surg Oncol 2024; 22:146. [PMID: 38822349 PMCID: PMC11143569 DOI: 10.1186/s12957-024-03428-z] [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: 03/12/2024] [Accepted: 05/27/2024] [Indexed: 06/02/2024] Open
Abstract
BACKGROUND Delayed epistaxis after endoscopic transnasal pituitary tumor resection (ETPTR) is a critical complication, tending to cause aspiration or hemorrhagic shock. This study assessed clinical characteristics, risk factors, and provide treatment and prevention advice of this complication. METHODS This was a retrospective monocentric analysis of 862 patients who underwent ETPTR. Statistical analyses of clinical data revealed the incidence, sources and onset time of delayed epistaxis. Univariate analysis and binary logistic regression were used to identify risk factors. RESULTS The incidence of delayed epistaxis was 2.78% (24/862), with an average onset time of 20.71 ± 7.39 days. The bleeding sources were: posterior nasal septal artery branch of sphenopalatine artery (12/24), multiple inflammatory mucosae (8/24), sphenopalatine artery trunk (3/24) and sphenoid sinus bone (1/24). Univariate analysis and binary logistic regression analysis confirmed that hypertension, nasal septum deviation, chronic rhinosinusitis and growth hormone pituitary tumor subtype were independent risk factors for delayed epistaxis. Sex, age, history of diabetes, tumor size, tumor invasion and operation time were not associated with delayed epistaxis. All patients with delayed epistaxis were successfully managed through endoscopic transnasal hemostasis without recurrence. CONCLUSIONS Delayed epistaxis after ETPTR tends to have specific onset periods and risk factors. Prevention of these characteristics may reduce the occurrence of delayed epistaxis. Endoscopic transnasal hemostasis is recommended as the preferred treatment for delayed epistaxis.

Cancers (Basel) 2023; 15:cancers15082235.

Abstract
The evolution of endoscopic trans-sphenoidal surgery raises the question of the role of transcranial surgery for pituitary tumors, particularly with the effectiveness of adjunct irradiation. This narrative review aims to redefine the current indications for the transcranial approaches for giant pituitary adenomas in the endoscopic era. A critical appraisal of the personal series of the senior author (O.A.-M.) was performed to characterize the patient factors and the tumor's pathological anatomy features that endorse a cranial approach. Traditional indications for transcranial approaches include the absent pneumatization of the sphenoid sinus; kissing/ectatic internal carotid arteries; reduced dimensions of the sella; lateral invasion of the cavernous sinus lateral to the carotid artery; dumbbell-shaped tumors caused by severe diaphragm constriction; fibrous/calcified tumor consistency; wide supra-, para-, and retrosellar extension; arterial encasement; brain invasion; coexisting cerebral aneurysms; and separate coexisting pathologies of the sphenoid sinus, especially infections. Residual/recurrent tumors and postoperative pituitary apoplexy after trans-sphenoidal surgery require individualized considerations. Transcranial approaches still have a critical role in giant and complex pituitary adenomas with wide intracranial extension, brain parenchymal involvement, and the encasement of neurovascular structures.

Abstract
BACKGROUND Landmarks for transsphenoidal surgery have been described to facilitate resection for pituitary lesions. However, carrying out sphenoidotomy for access to the sellar floor could still be challenging, especially for young surgeons during the steep learning curve. OBJECTIVE We describe the LUTH (Lagos University Teaching Hospital) line as a simple anatomic guide to avoid missing the trajectory to the sella during anterior sphenoidotomy in microscopic transsphenoidal pituitary surgery. METHODS We identified this line as an impression on the floor of the sphenoid sinus across the point at which the floor of the anterior cranial fossa and the bony projection from the clivus meet. We carried out a literature review of articles describing landmarks for anterior sphenoidotomy using data obtained from PubMed and Ovid MEDLINE databases according to PRISMA guidelines. RESULTS A total of 80 patients were operated using the LUTH line as a guide for anterior sphenoidotomy during microscopic transsphenoidal pituitary. We did not find any previous description of this anatomic landmark over the anterior sphenoid sinus in the literature. The LUTH line was clearly identified in all 80 cases. The line was used as a bony landmark to the sphenoid sinus in all cases and was found to be consistently accurate. CONCLUSIONS The LUTH line is a consistent and easy-to-identify landmark that could be useful in preventing potential complications of access to the pituitary sella through the sphenoid sinus. We believe it to be useful in the absence of intraoperative guidance, especially for young surgeons who are just starting off their career in pituitary surgery.

Abstract
PURPOSE Endonasal resection is the first-line treatment for patients harboring growth hormone (GH)-secreting pituitary adenomas. The complexity of the parasellar neurovascular structures makes pre-operative diagnostic imaging essential to understanding the anatomy of this region. We aimed to describe vascular anomalies in acromegalic patients and emphasize their relevance for surgery and preoperative planning. METHODS A systematic review following the PRISMA statement was performed in July 2021. RESULTS Thirty-three studies were evaluated. Elevated GH and insulin-like growth factor-1 (IGF-1) levels are linked to the occurrence of cardiovascular risk factors. This is attributed to endothelial dysfunction, mainly caused by changes in flow-mediated dilatation (FMD), which is probably the main cause of vascular anomalies in acromegaly. The occurrence of protrusions of the internal carotid artery (ICA) (35-53%), a narrow intercarotid distance, and an asymmetrical course was described. In 13-18% of acromegalic patients, the presence of an intracerebral aneurysm could be reported (incidence in the general population:0.8-1.3%). The selected studies were however performed with a small patient sample (range:1-257). We present a case report of a 57y/o male patient with anomalies of the ICA ("kissing carotid arteries") harboring a GH-secreting adenoma, which was resected via an endoscopic endonasal approach. CONCLUSIONS There is an association between acromegaly and endothelial dysfunction, which increases cardiovascular risk factors and vascular anomalies. Preoperative vascular imaging, e.g., CT angiography, should be implemented as a standard to identify patients at risk and estimate surgical morbidity. However, no evidence-based recommendations exist so far, so future studies are necessary.

Abstract
OBJECTIVE The most common surgical technique for the management of pituitary adenomas is the endoscopic endonasal transsphenoidal approach (EEA). preoperative neuroimaging along with detecting surgical landmarks of the sphenoid sinus during surgery is important for making a successful operation. METHOD This study includes 1009 patients with pituitary adenomas who underwent EEA between 2013 and 2020. We evaluated the anatomical features of the sphenoid sinus through a panel of items obtained from imaging and intra-operative findings. RESULTS Our result includes 57.38% nonfunctional, 8.42% cushing, 12.39% prolactinoma, and 21.8% acromegaly patients who had undergone endoscopic endonasal transsphenoidal surgery. The mean age of the patients was 45 with a male to female ratio of 1.2:1. Sellar sphenoid type was the most common (91.8%) with only 12% symmetrical inter sphenoid septa, Internal carotid artery dehiscence was found in 1.7% of the cases. Apoplexy was present in 6.3% of patients, which was found more prevalent in nonfunctional adenomas (9.67%, Odds ratio: 4.85, 95% CI 2.24-11.79) and further investigation revealed a significant association between apoplexy and sphenoid mucosal edema and hemorrhage (Odds ratio: 43.0, 95% CI 22.50-84.26), and between apoplexy and cystic lesions (OR = 4.14, 95% CI 1.87-8.45, P-value < 0.0001). Acromegaly is associated with the increased number of lateral recces (Odds ratio: 11.41, 95% CI 7.54-17.52), septation of the sphenoid sinus (Marginal mean: 3.92, 95% CI 3.69-4.14), edematous sinonasal mucosa (Odds ratio: 6.7; 95% CI 4.46-10.08), and higher bony (OR: 4.81, 95% CI 2.60-8.97, P-value < 0.001) and cavernous (OR: 1.7, 95% CI 1.13-2.46, P-value < 0.01) invasion. CONCLUSION The present study provides anatomical data about the sphenoid sinus and its adjacent vital structures with adenomal specific changes that are necessary to prevent complications during endoscopic advanced transsphenoidal surgery.

Abstract
Growth Hormone-secreting adenomas exhibits variable biological behavior and heterogeneous natural history, ranging from small adenomas and mild disease, to invasive and aggressive neoplasms with more severe clinical picture. Patients not cured or controlled after neurosurgical and first-generation somatostatin receptor ligands (SRL) therapy could require multiple surgical, medical and/or radiation treatments to achieve disease control. To date, no clinical, laboratory, histopathological, or neuroradiological markers are able to define the aggressiveness or predict the disease prognosis in patients with acromegaly. Therefore, the management of these patients requires careful evaluation of laboratory assessments, diagnostic criteria, neuroradiology examinations, and neurosurgical approaches to choose an effective and patient-tailored medical therapy. A multidisciplinary approach is particularly useful in difficult/aggressive acromegaly to schedule multimodal treatment, which includes radiation therapy, chemotherapy with temozolomide and other, recent emerging treatments. Herein, we describe the role of the different members of the multidisciplinary team according to our personal experience; a flow-chart for the therapeutic approach of difficult/aggressive acromegaly patients is proposed.

Abstract
The endoscopic endonasal approach (EEA) provides a direct trajectory to ventral skull base lesions, avoidance of brain retraction, and clear visualization of cranial nerves as they exit skull base foramina. Despite these benefits, the EEA is not without complications. Here, we review published literature highlighting complications associated with the EEA including cerebrospinal fluid (CSF) leak, cranial nerve (CN) dysfunction, pituitary gland dysfunction, internal carotid artery (ICA) injury, infection, and others; we place special emphasis on discussing the prevention of these complications. As widespread adoption of the EEA continues, it becomes critical to educate surgeons regarding potential complications and their prevention while identifying gaps in the current literature to guide future research and advances in clinical care.

Abstract
BACKGROUND During skull base surgery, intraoperative internal carotid artery (ICA) injury is a catastrophic complication that can lead to fatal blood loss or secondary cerebral ischemia. Appropriate management of ICA injury plays a crucial role in the prognosis of patients. Neurosurgeons have reported multiple techniques and management strategies; however, the literature on managing this complication from the anesthesiologist’s perspective is limited, especially in the aspect of circulation management and airway management when patients need transit for further endovascular treatment.
CASE SUMMARY We describe 4 cases of ICA injury during neurosurgery; there were 3 cases of pathologically proven pituitary adenoma and 1 case of cavernous sinus endothelial meningioma. After the onset of ICA injury, all four patients were immediately transferred for endovascular therapy under general anesthesia with vital signs monitored and mechanical ventilation. Three patients were transferred to the hybrid operating room, and one patient was transferred to the catheter operating room. Three patients underwent covered stent implantation, and one patient underwent embolization. All four patients experienced hypovolemic shock and received blood products infusion and vasoactive drugs to maintain stable circulation. After the neurosurgery, one patient was extubated and returned to the ward, and the other three were delayed tracheal extubation and returned to the intensive care unit. One patient died from serious neurological complications after 62 d in the hospital, but the other three showed good clinical outcomes.
CONCLUSION ICA injury imposes a high risk of massive hemorrhage and subsequent infarction. Immediate treatment is critical and requires interdisciplinary collaboration among neurosurgeons, anesthesiologists, and interventional neuroradiologists. Effective hemostatic methods, stable hemodynamics sufficient to ensure perfusion of vital organs, airway safety during transit, rapid localization and implementation of appropriate measures to occlude the damaged vessel are strong guarantees of patient safety.

Abstract
PURPOSE Endoscope-assisted transsphenoidal surgery over the last few years has led to more radical excision of pituitary adenomas (PAs) with a low complication rate. Systematic registration of complications by experienced surgical teams could help to improve this technique while ameliorating the patients' quality of life. MATERIALS AND METHODS One hundred ten endoscopic procedures were performed in 94 patients with PAs (37 functional) by the same neurosurgical team of a tertiary center during the period 2014-2019. Post-surgical complications were analyzed and compared with data published during the last 5 years in the PubMed and Cochrane databases by performing a systematic review and meta-analysis of the literature. RESULTS The overall complication rate in our series was 23.4%. Diabetes insipidus (DI) and intraoperative cerebrospinal fluid (CSF) leakage were the commonest complications (12.8%), followed by postoperative hypopituitarism (9.2%) and hematoma (8.5%) during the follow-up of 2.15 ± 1.4 years. Syndrome of inappropriate antidiuretic hormone secretion, meningitis, deep vein thrombosis, and hyposmia were rare (< 3%). Postoperative hypopituitarism was significantly associated with incidence of hematoma. No statistically significant association was found between PAs Hardy and Knosp scale grading or between patients' characteristics with the occurrence of postoperative complications. Our meta-analysis including nine studies found no significant differences comparing the complications of endoscopic versus microscopic surgery. CONCLUSION The endoscopic approach is safe when performed by experienced surgical teams. CSF leakage and DI were the commonest complications in our series; however, confirmation by larger studies is required. Meta-analysis showed no statistically significant differences in complication rates comparing endoscopic versus microscopic surgery.

[PMID: 35654330 DOI: 10.1016/j.wneu.2022.05.059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 05/12/2022] [Accepted: 05/13/2022] [Indexed: 12/01/2022]
Abstract
BACKGROUND We evaluated the frequency of nasal pathologies and the significance of surgical access to the sellar region in patients who underwent an operation for sellar mass using the endonasal and microscopic transsphenoidal approaches. METHODS We retrospectively evaluated all patients who underwent surgery for pituitary macroadenoma using microscopic (n = 78) and endonasal (n = 20) transsphenoidal approaches. Patients' epicrisis, preoperative, and postoperative imaging as well as their operative notes were reviewed. Nasal pathologies and surgeries performed before or during the pituitary surgery were also documented. All endonasal surgeries were binostril and performed jointly by an ear, nose, and throat specialist and neurosurgeon. To determine the feasibility of endonasal and microscopic approaches, we developed an algorithm using the septum deviation classifications to determine the need for septoplasty. RESULTS The most common nasal pathology was septum deviation (n = 17; 17.3%). Of the other nasal pathologies, 6 cases (6%) were chronic sinusitis and 2 were (2.1%) middle turbinate bullosa. CONCLUSIONS The preoperative evaluation of patients undergoing endonasal transsphenoidal surgery by an ear, nose, and throat surgeon allows for the detection and treatment of nasal pathologies that may lead to serious perioperative and postoperative complications. Evaluating patients with septum deviation using our classification will help determine the necessity of preoperative or perioperative septum surgery, depending on the preferred pituitary surgical method.

Abstract
Acromegaly is a disease that occurs secondary to high levels of GH, most often from a hormone-secreting pituitary adenoma, with multisystem adverse effects. Diagnosis includes serum GH and IGF-1 levels, and obtaining an MRI pituitary protocol to assess for a functional pituitary adenoma. Attempted gross total resection of the GH-secreting adenoma is the gold standard in treatment for patients with acromegaly for a goal of biochemical remission. Medical and radiation therapies are available when patients do not achieve biochemical cure after surgical therapy.

Abstract
Internal carotid artery (ICA) injury is a catastrophic complication of endoscopic endonasal surgery (EES). However, its standard management, emergent endovascular treatment, may not always be available, and the transnasal approach may be insufficient to achieve hemostasis. A 44-year-old woman with pituitary adenoma underwent EES complicated with the ICA cavernous segment injury (CSI). In urgent intraoperative angiogram, a good collateral flow from the contralateral carotid circulation was observed. Due to the unavailability of intraoperative embolization, emergent surgical trapping was performed by combined transcranial and cervical approach. The patient recovered but later developed a giant cavernous pseudoaneurysm. During the pseudoaneurysm embolization, ICA was directly accessed via a 1.7-F puncture hole using a bare microcatheter technique. Then, both the aneurysm and parent artery were obliterated with coils. At the 4-year follow-up, the patient was asymptomatic without a residual tumor. To our knowledge, this is the first case of ICA-CSI during EES successfully treated with ICA trapping as a lifesaving urgent surgery that achieved a complete recovery after a pseudoaneurysm embolization. Although several studies reported that EES-related ICA-CSIs with percutaneous carotid artery access, neither our surgical salvage technique nor our carotid access and tract embolization techniques were previously described.

Abstract
OBJECTIVE Perioperative management of patients with sellar lesions is complex, requiring input from a multidisciplinary team of specialists for ongoing management of both endocrinological and neurosurgical issues. Here, the authors reviewed the experience of a single multidisciplinary center over 10 years to identify key postoperative practices that ensure positive outcomes for patients with sellar lesions who undergo transsphenoidal surgery. METHODS The authors performed a retrospective review of all transsphenoidal operations carried out by the senior author at a single center from April 2008 through November 2018. They included only adult patients and recorded perioperative management. They also reviewed the evolution of clinical practices for perioperative care at their institution to identify strategies for ensuring positive patient outcomes, and they reviewed the literature on select related topics. RESULTS In total, 1023 operations in 928 patients were reviewed. Of these, 712 operations were for pituitary adenomas (69.6%), and 122 were for Rathke cleft cysts (11.9%). The remainder included operations for craniopharyngiomas (3.6%), arachnoid cysts (1.7%), pituitary tumor apoplexy (1.0%), and other sellar pathologies (12.2%). Among the reviewed operations, the median hospital stay was 3 days (IQR 2-3). Patient management details during the pre-, intra-, and postoperative periods were identified, including both shared characteristics of all patients undergoing transsphenoidal surgery and unique characteristics that are specific to certain lesion types or patient populations. CONCLUSIONS Patients with sellar lesions who undergo transsphenoidal surgery require complex, multidisciplinary perioperative care to monitor for common adverse events and to improve outcomes, but there is a dearth of high-quality evidence guiding most perioperative practices. Here, the authors reviewed practices at their institution across more than 1000 transsphenoidal operations that may help ensure successful patient outcomes.

Incidence and Factors Associated with Postoperative Delayed Hyponatremia after Transsphenoidal Pituitary Surgery: A Meta-Analysis and Systematic Review. Int J Endocrinol 2021; 2021:6659152. [PMID: 33936198 PMCID: PMC8055398 DOI: 10.1155/2021/6659152] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 03/02/2021] [Accepted: 03/08/2021] [Indexed: 12/12/2022] Open
Abstract
INTRODUCTION Postoperative delayed hyponatremia is a complication associated with transsphenoidal pituitary surgery. Due to a wide spectrum of symptoms, the reported incidence and predictors of postoperative delayed hyponatremia vary among studies, and this deserves to be reviewed systematically. METHODS PubMed, EMBASE, and CENTRAL databases were searched until September 1, 2020. Studies were included when (1) the event number of delayed hyponatremia after transsphenoidal pituitary surgery was reported, or (2) the associated factors of such complication were evaluated. RESULTS A total of 27 studies were included for meta-analysis. The pooled incidence of overall and symptomatic delayed hyponatremia was 10.5% (95% confidence interval (CI) = 7.4-14.7%) and 5.0% (95% CI = 3.6-6.9%), respectively. No overt variations of the pooled estimates were observed upon subgroups stratified by endoscopic and microscopic procedure, publication year, and patients' age. In addition, 44.3% (95% CI = 29.6-60.2%) of unplanned hospital readmissions within 30 days were caused by delayed hyponatremia. Among the predictors evaluated, older age was the only significant factor associated with increased delayed hyponatremia (odds ratio = 1.16, 95% CI = 1.04-1.29, P = 0.006). CONCLUSION This meta-analysis and systematic review evaluated the incidence of postoperative delayed hyponatremia and found it as a major cause of unplanned readmissions after transsphenoidal pituitary surgery. Older patients are more prone to such complications and should be carefully followed. The retrospective nature and heterogeneity among the included studies and the small number of studies used for risk factor evaluation might weaken the corresponding results. Future prospective clinical studies are required to compensate for these limitations.

Abstract
BACKGROUND Endoscopic skull-base surgery (ESBS) is employed in the management of diverse skull-base pathologies. Paralleling the increased utilization of ESBS, the literature in this field has expanded rapidly. However, the rarity of these diseases, the inherent challenges of surgical studies, and the continued learning curve in ESBS have resulted in significant variability in the quality of the literature. To consolidate and critically appraise the available literature, experts in skull-base surgery have produced the International Consensus Statement on Endoscopic Skull-Base Surgery (ICAR:ESBS). METHODS Using previously described methodology, topics spanning the breadth of ESBS were identified and assigned a literature review, evidence-based review or evidence-based review with recommendations format. Subsequently, each topic was written and then reviewed by skull-base surgeons in both neurosurgery and otolaryngology. Following this iterative review process, the ICAR:ESBS document was synthesized and reviewed by all authors for consensus. RESULTS The ICAR:ESBS document addresses the role of ESBS in primary cerebrospinal fluid (CSF) rhinorrhea, intradural tumors, benign skull-base and orbital pathology, sinonasal malignancies, and clival lesions. Additionally, specific challenges in ESBS including endoscopic reconstruction and complication management were evaluated. CONCLUSION A critical review of the literature in ESBS demonstrates at least the equivalency of ESBS with alternative approaches in pathologies such as CSF rhinorrhea and pituitary adenoma as well as improved reconstructive techniques in reducing CSF leaks. Evidence-based recommendations are limited in other pathologies and these significant knowledge gaps call upon the skull-base community to embrace these opportunities and collaboratively address these shortcomings.

Abstract
OBJECTIVE Internal carotid artery (ICA) injuries during endoscopic endonasal surgery (EES) are catastrophic complications. Alongside the advancements in medical instrumentation and material, there is a need to modify previous treatment modalities and principles. METHODS A retrospective review of 3658 patients who underwent EES performed at the authors' institution between January 2012 and December 2017 was conducted. Ultimately, 20 patients (0.55%) with ICA injury following EES were enrolled for analysis. Data collection included demographic data, preoperative diagnosis, injury setting, repair method, and immediate and follow-up angiographic and clinical outcomes. RESULTS Among the 20 patients, 11 received immediate endovascular therapy and 9 were treated only with packing. Of the 11 patients who received endovascular treatment, 6 were treated by covered stent and 5 by parent artery occlusion (PAO). The preservation rate of injured ICA increased from 20.0% (1 of 5) to 83.3% (5 of 6) after the Willis covered stent graft became available in January 2016. Of the 20 patients in the study, 19 recovered well and 1 patient-who had a pseudoaneurysm and was treated by PAO with a detachable balloon-suffered epistaxis after the hemostat in her nasal cavity was removed in ward, and she died later that day. The authors speculated that the detachable balloon had shifted to the distal part of ICA, although the patient could not undergo a repeat angiogram because she quickly suffered shock and could not be transferred to the catheter room. After the introduction of a hybrid operating room (OR), one patient whose first angiogram showed no ICA injury was found to have a pseudoaneurysm. He received endovascular treatment when he was brought for a repeat angiogram 5 days later in the hybrid OR after removing the hemostat in his nasal cavity. Of the 4 surviving patients treated with PAO, no external carotid artery-ICA bypass was required. The authors propose a modified endovascular treatment protocol for ICA injuries suffered during EES that exploits the advantage of the covered stent graft and the hybrid OR. CONCLUSIONS The endovascular treatment protocol used in this study for ICA injuries during EES was helpful in the management of this rare complication. Willis stent placement improved the preservation rate of injured ICA during EES. It would be highly advantageous to manage this complication in a hybrid OR or by a mobile C-arm to get a clear intraoperative angiogram.

Abstract
BACKGROUND For the precise removal of pituitary tumors, preserving the surrounding normal structures, we need real-time intraoperative information on tumor location, margins, and surrounding structures. The aim of this study was to evaluate the benefits of a new intraoperative real-time imaging modality using indocyanine green (ICG) fluorescence through an endoscopic system during transsphenoidal surgery (TSS) for pituitary tumors. METHODS Between August 2013 and October 2014, 20 patients with pituitary and parasellar region tumors underwent TSS using the ICG fluorescence endoscopic system. We used a peripheral vein bolus dose of 6.25 mg/injection of ICG, started with a time counter, and examined how each tissue type increased and decreased in fluorescence through time. RESULTS A total of 33 investigations were performed for 20 patients: 9 had growth hormone secreting adenomas, 6 non-functioning pituitary adenomas, 3 Rathke's cleft cysts, 1 meningioma, and 1 pituicytoma. After the injection of ICG, the intensity of fluorescence of tumor and normal tissues under near-infrared light showed clear differences. We could differentiate tumor margins from adjacent normal tissues and define clearly the surrounding normal structures using the different fluorescent intensities time changes and tissue-specific fluorescence patterns. CONCLUSIONS The ICG endoscopic system is simple, user-friendly, quick, cost-effective, and reliable. The method offered real-time information during TSS to delimit pituitary and parasellar region tumor tissue from surrounding normal structures. This method can contribute to the improvement of total removal rates of tumors, reduction of complications after TSS, saving surgical time, and preserving endocrinological functions.

Abstract
PURPOSE To assess and quantify the prevalence and co-occurence of a sellar floor lowering and empty sella phenomenon in patients with GH (growth hormone)-secreting pituitary adenoma. METHODS A total number of 159 acromegalic patients were included in this study, as well as two control groups (150 patients with non-GH-secreting adenomas and 50 patients without pituitary adenomas). Magnetic resonance images of all patients were evaluated for presence of an empty sella, downward and lateral tumor extension, and maximum superoinferior diameter of the mass. Additionally, these values were correlated with growth hormone and IGF-1 levels. RESULTS The empty sella phenomenon was detected significantly more often in patients with a GH-secreting adenoma with a prevalence of 22% vs. 5.3% in non-GH-secreting adenomas (p < 0.001) or 8% in the healthy control group (p = .036). Moreover, GH-secreting adenomas presented with a significant rate of downward tumor extension (74.8% vs. 35.5%; p < 0.001), whose extent correlated inversely but weakly with the GH hormone level (r = - 0.17; p = .036). It was also found that a decreased superoinferior diameter and higher ratio of intrasellar to suprasellar extension are predictive quantitative values for the presence of a GH-secreting adenoma (area under curve, 0.712). CONCLUSIONS GH-secreting pituitary adenomas are frequently associated with an empty sella phenomenon. Moreover, GH-secreting adenomas are frequently accompanied by an enhanced, quantitatively measurable impression of the sellar floor. Hypothetically, this is caused by tumor-induced local bone remodeling processes.

Abstract
Objectives Perioperative airway management may be particularly challenging in patients with acromegaly undergoing trans‐sphenoidal pituitary surgery (TSS). Management for airway obstruction is required prior to pituitary surgery to minimize perioperative hypoxia. The purpose of this retrospective study was to evaluate airway obstruction by simulation of computational fluid dynamics (CFD) using computed tomography (CT) images in patients who had undergone TSS. Methods CT images of the nasopharyngeal airways of patients with acromegaly (n = 5) or nonfunctional pituitary adenoma (n = 6) undergoing TSS from April 2012 to January 2017 were used to construct these airways in three dimensions. Estimated airflow pressure and velocity in the retropalatal airway (RA), oropharyngeal airway (OA), and hypopharyngeal airway (HA) were simulated using CFD. Results Estimated pharyngeal airflow pressure in the HA, OA, and RA was significantly greater in patients with acromegaly than in those with nonfunctional pituitary adenomas whereas the estimated pharyngeal airflow velocity was significantly impaired only in the RA of patients with acromegaly. Minimum postoperative SpO2 both within 3 hours and from 3 to 12 hours after the end of anesthesia was significantly lower in the patients with acromegaly. Additionally, estimated volume of tongue and pharyngeal airflow pressure in the HA, OA, and RA correlated with minimum postoperative SpO2. Conclusion Pharyngeal airflow pressure estimated from CT images is high in patients with acromegaly, and these values correlate with postoperative minimum values for SpO2. Preoperative evaluation of CT images by CFD can predict difficulty in airway management and perioperative hypoxia. Level of Evidence 4.

History, Current Situation, and Future Development of Endoscopic Neurosurgery in China. World Neurosurg 2017; 110:270-275. [PMID: 29180086 DOI: 10.1016/j.wneu.2017.11.103] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2017] [Revised: 11/16/2017] [Accepted: 11/18/2017] [Indexed: 11/22/2022]
Abstract
OBJECTIVE During the past few decades, Chinese endoscopic neurosurgery has rapidly developed in synchrony with the rest of the world. The aim of this article is to review the development of Chinese endoscopic neurosurgery, including its birth, growth, current situation, and prospects. METHODS The history of Chinese endoscopic neurosurgery development can be divided into 3 stages: cognition and initial stage (1964-1995), exploration and maturity stage (1995-2006), and rapid development and promotion stage (2006-present). RESULTS In the first stage, we mainly began to become aware of endoscopic neurosurgery from the translation and review of literature. In the mid to late 1990s, Chinese neurosurgery pioneers began using neuroendoscopic techniques. In the following decade, many leading neurosurgeons made persistent efforts to push the development of Chinese endoscopic neurosurgery forward, focusing on advocating for and promoting and popularizing neuroendoscopic technology. In the rapid development and promotion stage, many representative national and regional neurosurgical centers became skilled and efficient in the application of neuroendoscopic technology and became new advocates of the technology. The number of cases, level of technology, and treatment effectiveness are gradually nearing international standards. However, future development requires promotion of balanced development to decrease regional disparities, further strengthen international exchanges, follow the latest developments, and constantly innovate for continuous improvement. CONCLUSIONS Following the dramatic efforts of several pioneers, development of Chinese endoscopic neurosurgery has been considerable, and it has become an important component of neurosurgery worldwide.

Abstract
PURPOSE The goal of this study was to quantified the results of microsurgery, in all the patients with acromegaly treated by the same endocrinologist and the same surgeon between 1975 and 2015. METHODS A series of 548 patients with acromegaly were operated and followed-up from 6 months to 40 years. Patients were selected according to five criteria: (1) Operated by the same surgeon. (2) No previous treatment. (3) Complete endocrinological preoperative studies including GH, OGTT, IGF-I, PRL test and TC/MRI. (4) Complete postoperative endocrinological evaluation for at least one determination of GH, OGTT, PRL test and IGF-I six months after surgery. (5) All the patients were supervised by the same endocrinologist. RESULTS Microadenomas were present in 119 patients and 109 (91,5%) achieved remission. Non invasive macroadenomas were present in 200 patients and 164 achieved remission (82%). Results were worse for invasive macroadenomas but even with great invasions some patients achieved clinical remission. Follow-up range from 6 months to 40 years (mean 3.3 ± 2.3) A long term follow-up of 15 years was achieved in 61 patients. Four of them had a recurrence 4, 7, 8, 12 years after surgery (6.5%). There was not mortality and the rate of complications was low. CONCLUSIONS Surgery remains the first line of therapy for a majority of acromegalic patients. This series proves to be very valuable in circumscribed adenomas but also in invasive tumours. Levels of GH and IGF-I were decreased in almost all the patients without remission.

Abstract
Objective To evaluate the intercarotid distance (ICD) of patients with pituitary macroadenoma and compare to heatlhy controls. Method We retrospectively reviewed contrast-enhanced MRI images from twenty consecutive patients diagnosed with non-functioning pituitary macroadenoma, measured the ICD at two different levels (petrous segment - ICD1 and horizontal cavernous segment - ICD2) and compared to twenty paired controls. Results There was no statistically significant difference of the mean ICD1 between the groups and subgroups. For the ICD2 there was statistically significant difference between the case and controls. However, there was no significant difference between the patients with smaller adenomas and the controls. In contrast, the patients with giant adenomas showed statistically significantly higher ICD2 than the controls. Conclusion The ICD at the horizontal segment of the cavernous carotid tends to be wider in patients with giant pituitary adenomas than in healthy individuals or patients with smaller adenomas.

Abstract
Objectives/Hypotheses Functioning pituitary adenomas may produce endocrinopathies such as acromegaly and Cushing syndrome. Both conditions lead to characteristic anatomic variations as a result of hormonally induced abnormal soft tissue deposition. We evaluate the anatomic differences between acromegalics and Cushing disease patients and compare these dimensions to controls. Design Radiographic review of preoperative magnetic resonance images (MRI) of the pituitary gland. Setting Tertiary academic medical center. Participants Patients who underwent transnasal, transsphenoidal surgery for pituitary adenomas found to have acromegaly or pituitary Cushing between January 1, 2007 and September 1, 2015. A total of 15 patients with similar MRIs and no history of pituitary or sinonasal disease were selected as controls. Main Outcome Measures Dimensions assessed were intercarotid distance; carotid canal width; piriform aperture width; distance from the piriform aperture to the anterior face of the sphenoid; sphenoid sinus height, width, and length; angle from anterior nasal spine to anteroinferior face of sphenoid sinus; choanal height; and nasal cavity height at the level of the vertical segment of the middle turbinate. Sphenoid sinus pneumatization patterns were recorded. Results There were 30 acromegalics and 31 Cushing disease patients. When compared with controls, both acromegalics and Cushing disease patients had significantly wider piriform apertures and a longer distance from the piriform aperture to the anterior face of the sphenoid sinus (p < 0.05). Acromegalics had a significantly less acute angle (19 ± 3 degrees) from the anterior nasal spine to the sphenoid (p < 0.05). Cushing disease patients had significantly lower sphenoid sinus length and shorter nasal cavity height (p < 0.05). There were no differences in intercarotid distance or carotid canal width. Conclusions As acromegalics and Cushing disease patients have known anatomic variations, the skull base surgeon should be aware of these differences and adapt their techniques and approaches as needed.

Abstract
OBJECTIVE Diabetes insipidus (DI) is a well-known complication of transsphenoidal pituitary adenoma surgery. However, the risk factors for DI after transcranial surgery have not been clarified. In this study, the clinical parameters for predicting DI after transcranial surgery were investigated. METHODS The perioperative records of 90 patients who underwent transcranial (TC) surgery at the authors' institution between November 2011 and March 2013 were chosen from 1657 patients with pituitary adenoma and retrospectively analyzed. The degree of deformation of the third ventricle and hypothalamus were assessed by preoperative magnetic resonance imaging. RESULTS Immediate postoperative DI was found in 30 patients (33.3%). Persistent DI was noted in 11 patients (12.6%). Compared with patients in the nonpostoperative DI group, those with postoperative DI had a higher degree of deformation of the third ventricle and hypothalamus (P < 0.001). In a binary logistic regression analysis, the degree of deformation of the third ventricle and hypothalamus (odds ratio [OR], 3.079; 95% confidence interval [CI], 1.600-5.925; P = 0.001) had a significant positive correlation with immediate postoperative DI, as well as postoperative hemorrhage (OR, 6.235, 95% CI, 1.457-26.689; P = 0.014). Postoperative hemorrhage (OR, 4.363; 95% CI, 1.021-18.647; P = 0.047) showed a positive correlation with permanent DI, as well as the degree of deformation of the third ventricle and hypothalamus (OR, 2.336; 95% CI, 1.005-5.427; P = 0.049). CONCLUSIONS The degree of deformation of the third ventricle and hypothalamus assessed by preoperative magnetic resonance imaging may help to predict postoperative DI. Postoperative hemorrhage might increase the incidence of postoperative DI, whether it is immediate postoperative DI or permanent DI.

Abstract
PURPOSE Acromegaly is a systemic disease which causes multiple bony alterations. Some authors reported that acromegalic patients have risk factors for an intraoperative vascular injury due to the specific anatomical features of their sphenoid sinus. The objective of our study was to analyze the anatomic characteristics of sphenoid sinus in acromegalic patients compared with controls, by evaluation of computed tomography (CT) findings. METHODS We examined 45 acromegalic (acromegaly group) and 45 non-acromegalic patients (control group) with pituitary adenomas who were matched for sex, age, height, tumor size, and cavernous sinus invasion (Knosp grade). Preoperative CT of the pituitary region including the sphenoid sinus was used to evaluate the following anatomic characteristics: type of sphenoid sinus (sellar or pre-sellar/conchal); intrasphenoid septa (non/single or multiple); carotid artery protrusion; carotid artery dehiscence; intercarotid distance. RESULTS Sixteen acromegalic patients (35.5 %) and 6 controls (13.3 %) had carotid artery protrusion. Additionally, 10 acromegalic patients (22.2 %) and 3 controls (6.6 %) had carotid artery dehiscence. Carotid artery protrusion and dehiscence were more frequent in the acromegaly group than in control group (p = 0.013 and 0.035, respectively). Other anatomic characteristics (type of sphenoid sinus, intrasphenoid septa, and intracarotid distance) showed no significant differences between acromegaly and control groups. CONCLUSIONS Our study suggests that carotid artery protrusion and dehiscence occur more frequently among acromegalic patients, compared with non-acromegalic patients. It is important for surgeons to be aware of these anatomic variations to avoid vital complications, such as carotid injuries, during surgery.

Abstract
OBJECTIVE Internal carotid artery (ICA) injury is a rare but severe complication of endonasal surgery. The authors describe their endovascular experience managing ICA injuries after transsphenoidal surgery; they review and summarize the current literature regarding endovascular techniques; and they propose a treatment algorithm based on the available evidence. METHODS A retrospective review of 576 transsphenoidal pituitary adenoma resections was performed. Cases of ICA injury occurring at our institution and transfers from other hospitals were evaluated. Endovascular treatments for ICA injury reported in the literature were also reviewed and summarized. RESULTS Seven cases were identified from the institutional cohort (mean age 46.3 years, mean follow-up 43.4 months [1-107 months]) that received endovascular treatment for ICA injury. Five injuries occurred at our institution (5 [0.9%] of 576), and 2 injuries occurred at outside hospitals. Three patients underwent ICA sacrifice by coil placement, 2 underwent lesion embolization (coil or stent-assisted coil placement), and 2 underwent endoluminal reconstruction (both with flow diversion devices). Review of the literature identified 98 cases of ICA injury treated with endovascular methods. Of the 105 total cases, 46 patients underwent ICA sacrifice, 28 underwent lesion embolization, and 31 underwent endoluminal reconstruction. Sacrifice of the ICA proved a durable solution in all cases; however, the rate of persistent neurological complications was relatively high (10 [21.7%] of 46). Lesion embolization was primarily performed by coil embolization without stenting (16 cases) and stent-assisted coiling (9 cases). Both techniques had a relatively high rate of at least some technical complication (6 [37.5%] of 16 and 5 [55.6%] of 9, respectively) and major technical complications (i.e., injury, new neurological deficit, or ICA sacrifice) (5 [31.3%] of 16 and 2 [22.2%] of 9, respectively). Endoluminal reconstruction was performed by covered stent (24 cases) and flow diverter (5 cases) placement. Covered stents showed a reasonably high rate of technical complications (10 [41.7%] of 24); however, 8 of these problems were resolved, leaving a small percentage with major technical complications (2 [8.3%] of 24). Flow diverter placement was also well tolerated, with only 1 minor technical complication. CONCLUSIONS Endovascular treatments including vessel sacrifice, coil embolization (with or without stent assistance), and endoluminal reconstruction offer a tailored approach to ICA injury management after endonasal surgery. Vessel sacrifice remains the definitive treatment for acute, uncontrolled bleeding; however, vessel preservation techniques should be considered carefully in select patients. Multiple factors including vascular anatomy, injury characteristics, and risk of dual antiplatelet therapy should guide best treatment, but more study is needed (particularly with flow diverters) to refine this decision-making process. Ideally, all endovascular treatment options should be available at institutions performing endonasal surgery.

Abstract
BACKGROUND Acromegaly is a multisystemic disease that requires a multidisciplinary approach. The aim of this study was to determine early and late remissions of patients who underwent surgery at our center and to evaluate relations between pathologic and radiologic properties of adenoma and medical and radiosurgical treatments with remissions. METHODS The medical records of 103 patients with acromegaly who underwent endoscopic endonasal transsphenoidal surgery in Cerrahpasa Medical Faculty, Istanbul University, between 2007 and 2014 were reviewed. Clinical, biochemical, radiologic, and pathologic properties were determined. RESULTS The total median follow-up time was 38 months [interquartile range: 24-53.5 months]. Thirty-two percent of the adenomas were microadenomas and 68% were macroadenomas The early remission rate was 51.5% and late remission was 75.2%. The sellar floor invasion was significantly lower in patients with early and late remissions (P = 0.01 and P = 0.009, respectively). The initial growth hormone (GH; P < 0.001), first-day GH (P = 0.03), 3-month GH (P = 0.001), insulin-like growth factor-1 (P = 0.004), and 6-month insulin-like growth factor-1 (P = 0.02) levels were significantly greater in patients with sellar floor invasion. The late remission rates (P = 0.004) were greter and reoperation needs (P = 0.05) were lower in patients with Ki-67 <3% than in patients with ≥3%. Seventy (68.6%) patients needed medical therapy during follow-up. CONCLUSIONS Late remission was achieved using a multidiciplinary approach in 75.2% of 103 patients with acromegaly, and young age, male sex, high Ki-67 and mitosis indices, and cavernous sinus and sellar-floor invasion had negative effects on clinical and biochemical control of the disease.

Abstract
PURPOSE Hypopituitarism is a possible complication of the surgical treatment of acromegaly. However, there is a wide variability in the incidence rates of surgery-induced hypopituitarism. The purpose of this study was the systematic collection and synthesis of information on the incidence rates of hypopituitarism, panhypopituitarism, specific axis deficiencies and diabetes insipidus after surgery for acromegaly treatment. METHODS We systematically reviewed all the papers that have reported pituitary deficits after surgery for acromegaly published up until December 2014, in the PubMed database. We identified 92 studies enrolling 6988 patients. A meta-analysis was performed to evaluate the incidence rates. We also performed several subgroup analyses to evaluate the impact of both surgical technique, and treatment prior to surgery, on the results. RESULTS The weighted incidence rates were 12.79 % for hypopituitarism (95 % CI 9.88-16.00 %), 2.50 % for panhypopituitarism (95 % CI 1.24-4.15 %), 6.50 % for ACTH deficiency (95 % CI 4.07-9.44 %), 4.39 % for TSH deficiency (95 % CI 2.99-6.04 %), 6.70 % for FSH/LH deficiency (95 % CI 3.89-10.17 %), 14.95 % for GH deficiency (95 % CI 7.25-24.64 %), 10.05 % for transient (95 % CI 7.18-13.33 %) and 2.42 % for permanent diabetes insipidus (95 % CI 1.70-3.27 %). CONCLUSION Our study provides new data on the incidence rates of hypopituitarism, specific pituitary axis deficiencies and diabetes insipidus after surgical treatment of acromegaly. Somatotroph function appears to be more prone to deficit than the other axes. However, there is a high heterogeneity between studies and several factors may influence the incidence of hypopituitarism.

Abstract
OBJECT Oculomotor cistern extension of pituitary adenomas is an overlooked feature within the literature. In this study, 7 cases of pituitary macroadenoma with oculomotor cistern extension and tracking are highlighted, and the implications of surgical and medical management are discussed. METHODS The records of patients diagnosed with pituitary macroadenomas who underwent resection and in whom preoperative pituitary protocol MRI scans were available for review were retrospectively reviewed. The patient and tumor characteristics were reviewed along with the operative outcomes and complications. RESULTS Seven patients (4.1%) with oculomotor cistern extension and tracking were identified in a cohort of 170 patients with pituitary macroadenoma. The most common presenting symptoms were visual deficit (6 patients; 86%), apoplexy (3 patients; 43%), and oculomotor nerve palsy (3 patients; 43%). Lone oculomotor nerve palsy was seen in 2 patients without apoplexy and 1 patient with an apoplectic event. Gross-total resection was achieved via a microscopic endonasal transsphenoidal approach with or without endoscopic aid to the sella in 14%, near-total resection in 29%, and subtotal resection in 57% of patients in the data set. CONCLUSIONS Pituitary adenoma extension along the oculomotor cistern is uncommon; however, preoperatively recognizing such extension should play an important role in the surgeon's operative considerations and postoperative clinical management because this extension can limit gross-total resection using the transsphenoidal approach alone.

Abstract
OBJECTIVES/HYPOTHESIS Internal carotid artery (ICA) injury during endoscopic endonasal surgery (EES) is a known and feared complication of paranasal sinus and skull base procedures. These ICA injuries can result in stroke, cranial nerve palsies, and death. This review examines the setting of injury along with the treatment approaches, and patient outcomes. STUDY DESIGN Systematic review using PubMed/MEDLINE and EMBASE. METHODS The databases were searched for articles reporting cases of ICA injury during EES. Variables analyzed included patient demographics, operative approach, preoperative diagnosis, setting of injury, repair method, imaging studies, patient outcomes, and follow-up. RESULTS Twenty-five articles with 50 cases were included in this review. The EES approach was used for skull base procedures in 34 cases and for inflammatory disease in 16 cases. The most commonly injured ICA segment was the cavernous (34 cases), followed by the ophthalmic (three cases). Injuries occurred more commonly on the left (1.3:1). Injury occurred in the setting of various steps during EES with instruments. Stereotactic image guidance was reported in two cases. Initial hemostasis was achieved with packing in 35 cases, endoscopic clip sacrifice in four cases, bipolar coagulation with the intent to seal defect in three cases, and bipolar coagulation with the intent to sacrifice the ICA in one case. Intraoperative or immediate postoperative angiography was reported in 27 cases. CONCLUSIONS The incidence of reported cases of ICA injury during EES remains low. Left-sided injuries to the cavernous segment of the ICA occurred more frequently than injuries on the right. LEVEL OF EVIDENCE NA Laryngoscope, 126:582-590, 2016.

Abstract
Transsphenoidal surgery in the setting of acromegaly is quite challenging due to increased soft tissue mass, bony overgrowth, and bleeding. There is a debate on the endoscopic versus microscopic approach for these patients. The purpose of our study is to compare the outcomes for acromegaly after transsphenoidal surgery using both techniques. Retrospective review of 65 acromegalic patients who underwent transsphenoidal surgery in our department. Clinical remission was defined as resolution of typical acromegalic symptoms. Radiological resection was defined by volumetric criteria, and biochemical remission was defined as by the 2010 consensus on the criteria for remission of acromegaly. There was no significant difference in age, preoperative endocrine status, percent of macro adenomas, suprasellar, or infrasellar extension between both groups. Patients were assigned to both groups based on our existing referral pattern. Endoscopic approach was performed in 42 patients, while the microscopic approach was performed in 23 patients. No significant difference in remission rates was found between both groups (45.2 vs. 34.7 %, p = 0.40). The endoscopic group, however, had a significantly higher rate of gross total resections (61 vs. 42 %, p = 0.05). There was also a trend towards higher rates of gross total resections when cavernous sinus was present (48 vs. 14.2 %, p = 0.09). Postoperative diabetes insipidus occurred more in microscopic patients (34.7 vs. 17 %, p = 0.05), otherwise there was no significant difference in rates of complications. The median follow-up period was 56.6 months (range 6-156, mean 66.1). There is no significant difference in the rates of biochemical remission between the endoscopic and microscopic techniques. The endoscope technique, however, seems to be superior in achieving gross total resection especially with tumors invading the cavernous sinus.

Abstract
Aim To report the results of a series of patients undergoing pure endoscopic endonasal pituitary surgery and to evaluate the efficacy and safety of this procedure. Materials and methods The data of 1,166 patients that underwent endoscopic endonasal transsphenoidal adenoma removal between December 2006 and June 2013 were retrospectively reviewed. Pre- and postoperative hormonal status (3 months after surgery) were analyzed and compared with the clinical parameters originally presented by the patients. The incidences of tumor removal, hormonal control, and tumor removal complications were retrospectively analyzed. Result Out of 577 nonfunctioning adenomas, 180 were growth hormone (GH) secreting, 308 prolactin (PRL) secreting, 26 mixed GH/PRL adenomas, 68 adrenocorticotropin secreting, and 7 thyroid-stimulating hormone-secreting adenomas. The gross total removal of pituitary adenomas was achieved in 98 % of microadenomas, 92 % of macroadenomas, and 76 % of giant adenomas. Hormonal control was achieved in 47 (69 %) cases of ACTH adenomas, 119 (66 %) GH adenomas, 262 (85 %) PRL adenomas, and 6 (86 %) TSH adenomas. Postoperative complications were observed in 168 (14.4 %) patients. The most frequent complications were diabetes insipidus (7 %), epistaxis (1.7 %), hyposmia (1.5 %), anterior lobe insufficiency (1.3 %) ,and CSF leaks (0.6 %). Conclusion The pure endoscopic approach is a safe, efficacious, and minimally invasive technique for the removal of pituitary adenomas. A higher gross total resection rate is vital for non-functional and functional adenomas. For patients with functional adenomas, while hormonal remission is unlikely to be achieved by surgery, the use of adjuvant therapy is advocated to obtain long-term hormonal control.

Abstract
Among the major complications of transsphenoidal surgery, less attention has been given to severe postoperative epistaxis, which can lead to devastating consequences. In this study, we reviewed 551 consecutive patients treated over a 4 year period by the senior author to evaluate the incidence, risk factors, etiology and management of immediate and delayed post-transsphenoidal epistaxis. Eighteen patients (3.3%) developed significant postoperative epistaxis - six immediately and 12 delayed (mean postoperative day 10.8). Fourteen patients harbored macroadenomas (78%) and 11 of 18 (61.1%) had complex nasal/sphenoid anatomy. In the immediate epistaxis group, 33% had acute postoperative hypertension. In the delayed group, one had an anterior ethmoidal pseudoaneurysm, and one had restarted anticoagulation on postoperative day 3. We treated the immediate epistaxis group with bedside nasal packing followed by operative re-exploration if conservative measures were unsuccessful. The delayed group underwent bedside nasal hemostasis; if unsuccessful, angiographic embolization was performed. After definitive treatment, no patients had recurrent epistaxis.

Growth hormone secreting pituitary microadenomas and empty sella - An under-recognized association? Clin Neurol Neurosurg 2014; 126:18-23.

Abstract
OBJECTIVE To describe an association of growth hormone (GH) secreting pituitary microadenomas and empty sella (ES), which has been described in case reports - the underlying mechanisms are unclear. METHODS We retrospectively analyzed patients operated for GH-producing pituitary adenomas between February 2004 and February 2009. Magnetic resonance imaging (MRI), computed tomography (CT) imaging, and pituitary function testing were performed. All cases underwent transsphenoidal surgery (TSS). Mean follow up was 38 months (range 12-80 months). RESULTS Out of 152 patients with acromegaly due to GH-producing pituitary adenomas (female:male=73:79; age range 17-63 years), 69 patients had microadenomas (45.4%; 38 females, 31 males). We found 14 cases (14/69, 20.3%), all microadenomas, with presurgical evidence of ES - 10 females (71%) and 4 males (29%) (female:male=2.5:1). When compared with 103 patients with GH-negative microadenomas treated in the same time period (ES in 4 of 103; 3.9%), ES was highly significantly associated with GH production by the microadenoma (p=0.001). In acromegalics with empty sella, no cases of ectopic adenoma were found. Postoperatively, GH and IGF-1 levels fell in all patients, and 7 cases had random GH and IGF-1 levels consistent with cure. CONCLUSION The combination of GH-producing microadenomas and empty, enlarged sella is not rare. In this setting, preoperative CT scans are very useful and the transsphenoidal approach is efficient and safe. The mechanism underlying the association of GH-producing microadenomas and empty sella remains unclear and requires further studies.

Abstract
We describe a modification of the combined transseptal/transnasal binostril approach using a two-surgeon, four-handed technique (modified Stamm's approach) for pituitary lesions in patients with narrow nasal spaces. This approach comprises of a transseptal route through one nostril and a transnasal route without harvesting a pedicled nasoseptal flap (NSF) through the other. On the transseptal side, the nasal septum was removed using an endoscopic septoplasty technique. On the transnasal side, the mucosa containing the septal branch of the sphenopalatine artery over the face of the sphenoid and nasal septum was preserved for harvesting the NSF if an intraoperative cerebrospinal fluid leak was encountered. This approach was performed in six patients with pituitary lesions, including four non-functioning macroadenomas, one growth hormone-producing macroadenoma, and one Rathke's cleft cyst, all of which were associated with a severe deviation of the nasal septum and/or narrow nasal space. The meticulous and comfortable manipulation of an endoscope and instruments were achieved in all six patients without surgical complications. Our findings, although obtained in a limited number of cases, suggest that the modified Stamm's approach may be useful for selected patients, particularly those with a severe deviation of the nasal septum, without considerable damage to the nasal passages.

Abstract
PURPOSE To report our experience with intraoperative complications involving the internal carotid artery (ICA) during trans-sphenoidal surgery and their outcome with reconstructive endovascular management. METHODS A retrospective review was conducted of patients with an ICA injury related to trans-sphenoidal surgery from 2000 to 2012. Demographic data, clinical charts, indications for treatment, radiographic images, lesion characteristics, operative notes, endovascular procedure notes and post-procedure hospital course were reviewed. RESULTS Three men and one woman of mean age of 52 years (range 33-74) were identified. The lesions included two macroadenomas, one meningioma and one chondrosarcoma. Risk factors for ICA rupture included two patients with carotid dehiscence, one with sphenoid septal attachment to the ICA, two with revision surgery, one with prior radiation to the tumor, one with bromocriptine treatment and two with acromegaly. In three patients, covered stent placement achieved hemostasis at the site of injury within the ICA. One patient developed delayed bleeding 6 h after covered stent placement and underwent successful endovascular occlusion of the ICA but died 6 days after the injury. The fourth patient had an intraoperative ICA stroke requiring suction thrombectomy, thrombolysis, stent placement and evacuation of an epidural hematoma. At 1-year follow-up, two patients had a modified Rankin score (mRS) and National Institute of Health Stroke Scale (NIHSS) score of 0; in the patient who had a stroke the mRS score was 1 and the NIHSS score 2. CONCLUSIONS Endovascular management with arterial reconstruction is helpful in the treatment of ICA injuries during trans-sphenoidal surgery.

Abstract
Object
Acromegaly is a disease that has significant morbidity and mortality related to high levels of growth hormone (GH) and insulin-like growth factor–I (IGF-I), and is usually caused by pituitary adenomas. The goal in this study was to investigate the role of endoscopic transsphenoidal surgery and surgical experience in the treatment of GH adenoma cases in relation to surgical results and hormonal cure rates, and to perform a review of the literature.
Methods
The authors present a retrospective analysis of 214 GH adenoma cases. Restoration of IGF-I levels to normal for age and sex, suppression of GH levels below 0.4 μg/L on the oral glucose tolerance test, and demonstration of the total removal of the tumor on MRI studies obtained after administration of contrast material at the 3-month postoperative follow-up visit were the criteria for cure.
Results
In total 214 patients with a mean age of 41.9 ± 12 years (range 17–75 years) and a male/female ratio of 106/108 were enrolled in the study. Cure was achieved in 134 (62.6%) of 214 patients. One hundred sixty-nine patients were primary cases, and of these 109 (64.5%) were cured, whereas 61 patients were previously operated cases and of these 25 (41%) were cured. With a 51.1% decrease in the 1st month postoperatively, IGF-I levels were found to be predictive of cure (74.4% sensitivity and 73.7% specificity). Cut-off values for GH levels in predicting cure for the 1st day, 1st week, and 1st month postoperatively were 2.33, 2.05, and 2.25 μg/L, respectively.
The cut-off value for surgical experience was 57 for primary surgeries (58.5% cure rate before this cut-off value compared with 72.6% after it; p = 0.025) and 108 for all operations (45.8% vs 79.4%, p = 0.037). Although 28 patients were found to be in remission according to the criteria in 2000, they were not in remission according to the new consensus criteria. Nine of these cases (32.1%) had random GH levels < 1 μg/L at the 1-year follow-up. The 1-year IGF-I and GH levels in these 28 patients showed no significant difference when compared with the cases defined as cured according to the current criteria.
Conclusions
In acromegaly treatment, transsphenoidal endoscopic surgery performed by an expert senior surgeon and increased surgical experience are important for higher cure rates. Random GH levels < 2.33 μg/L after the 1st day postoperatively and a > 50% decrease in IGF-I levels after the 1st month postoperatively are predictive of cure. Moreover, there is no urgency for additional therapy in patients with GH levels of 0.4–1 μg/L and MRI sequences showing no tumor at the 3-month follow-up, because for these cases remission can be achieved at the 1-year follow-up.

Abstract
Diabetes insipidus (DI) after endoscopic transsphenoidal surgery (ETSS) can lead to increased morbidity, longer hospital stays, and increased medication requirements. Predicting which patients are at high risk for developing DI can help direct services to ensure adequate care and follow-up. The objective of this study was to review our institution's experience with ETSS and determine which clinical/laboratory variables are associated with DI in this patient population. The authors wanted to see if there was an easily determined single value that would help predict which patients develop DI. This represents the largest North American series of this type. We retrospectively reviewed the charts of patients who had undergone ETSS for resection of sellar and parasellar pathology between 2006 and 2011. We examined patient and tumor characteristics and their relationship to postoperative DI. Out of 172 endoscopic transsphenoidal surgeries, there were 15 cases of transient DI (8.7%) and 14 cases of permanent DI (8.1%). Statistically significant predictors of postoperative DI (p < 0.05) included tumor volume and histopathology (Rathke's cleft cyst and craniopharyngioma). Significant indicators of development of DI were postoperative serum sodium, preoperative to postoperative change in sodium level, and urine output prior to administration of 1-deamino-8-D-arginine vasopressin. An increase in serum sodium of ≥2.5 mmol/L is a positive marker of development of DI with 80% specificity, and a postoperative serum sodium of ≥145 mmol/L is a positive indicator with 98% specificity. Identifying perioperative risk factors and objective indicators of DI after ETSS will help physicians care for patients postoperatively. In this large series, we demonstrated that there were multiple perioperative risk factors for the development of DI. These findings, which are consistent with other reports from microscopic surgical series, will help identify patients at risk for diabetes insipidus, aid in planning treatment algorithms, and increase vigilance in high risk patients.

Abstract
BACKGROUND Surgeons undertaking transsphenoidal surgery in patients with acromegaly confront multiple unique challenges secondary to the anatomic alterations caused by growth hormone-secreting tumors. The senior author has noted a fusiform dilatation of the cavernous carotid artery in many acromegalic patients. The authors aim to quantify this dilatation and correlate it with potential contributing factors. METHODS Clinical and radiographic data were retrospectively assessed in acromegalic patients undergoing transsphenoidal surgery from 2000 through 2011. Randomly selected patients with nonsecreting pituitary adenomas were used as the control cohort. Demographic information, comorbidities, and preoperative growth hormone and insulin-like growth factor-1 levels were recorded. Magnetic resonance (MR) imaging variables included tumor size, diameters of the petrous, cavernous, and supraclinoid segments of the carotid artery, and extent and location of cavernous sinus invasion. Independent correlations between acromegaly and each variable were assessed with multivariate regression analysis. RESULTS Forty randomly selected patients with growth hormone-secreting adenomas who underwent surgery and had MR imaging with thin coronal slices of the pituitary region were enlisted in our study cohort. The mean age was 45.7 years. Forty-two males (52.5 %) were included in the study. Mean carotid artery diameter measurements for acromegalic and control patients, respectively, were 4.2 vs. 3.8 mm (petrous carotid), 5.0 vs. 4.0 mm (cavernous carotid), and 3.3 vs. 2.9 mm (supraclinoid carotid). Multivariate analysis showed only age and cavernous carotid diameter were statistically significant independent variables (p = 0.02, p < 0.001, respectively). Age, tumor size, growth-hormone or insulin-like growth factor-1 levels, and cavernous sinus invasion did not correlate with cavernous carotid artery diameter. CONCLUSIONS In patients with acromegaly, there is a fusiform dilatation of the cavernous carotid artery that must be considered when planning transsphenoidal surgery.

Abstract
Endoscopic endonasal trans-sphenoid surgery (EETS) is increasingly used for pituitary lesions. Pre-operative CT and MRI scans and peroperative endoscopic visualization can provide useful anatomical information. EETS is indicated in sellar, suprasellar, intraventricular, retro-infundibular, and invasive tumors. Recurrent and residual lesions, pituitary apoplexy and empty sella syndrome can be managed by EETS. Modern neuronavigation techniques, ultrasonic aspirators, ultrasonic bone curette can add to the safety. The binostril approach provides a wider working area. High definition camera is much superior to three-chip camera. Most of the recent reports favor EETS in terms of safety, quality of life and tumor resection, hospital stay, better endocrinological, and visual outcome as compared to the microscopic technique. Nasal symptoms, blood loss, operating time are less in EETS. Various naso-septal flaps and other techniques of CSF leak repair could help reduce complications. Complications can be further reduced after achieving the learning curve, good understanding of limitations with proper patient selection. Use of neuronavigation, proper post-operative care of endocrine function, establishing pituitary center of excellence and more focused residency and endoscopic fellowship training could improve results. The faster and safe transition from microscopic to EETS can be done by the team concept of neurosurgeon/otolaryngologist, attending hands on cadaveric dissection, practice on models, and observation of live surgeries. Conversion to a microscopic or endoscopic-assisted approach may be required in selected patients. Multi-modality treatment could be required in giant and invasive tumors. EETS appears to be a better surgical option in most pituitary adenoma.

Abstract
Endoscopic transsphenoidal surgery is emerging as a minimally invasive and maximally effective procedure for pituitary adenomas. In this report we analyzed the complications in 624 procedures of endonasal transsphenoidal endoscopic surgery in the treatment of 570 patients with pituitary adenomas. The leading author (MB) operated pituitary adenomas via pure endoscopic endonasal transsphenoidal surgery between January 2006 and August 2011 at the Hacettepe University, Department of Neurosurgery in Ankara. Complications were assessed in 624 surgical procedures under five groups; rhinological, CSF leaks, infection, vascular and endocrinologic complications. We observed a total of 76 complications (12.1%). Rhinological complications occurred in 8 patients (1.3%): 4 epistaxis (0.6%) and 4 hyposmia (0.6%). Postoperative CSF leaks occurred in 8 patients (1.3%), and infectious complications occurred in 8 patients: 3 cases of sphenoidal sinusitis (0.4%), 5 cases of meningitis (0.8%). Only 1 case of internal carotid aneurysm rupture during the opening of sellar floor (0.16%) was observed. Endocrinologic complications occurred in 51 (8.1%) patients: Anterior pituitary deficiency in 12 (1.9%), transient diabetes insipidus (DI) in 29 (4.6%), permanent DI in 3 (0.4%) and inappropriate antidiuretic hormone secretion syndrome occurred in 7 (1.1%). There was no mortality directly related to the surgical procedure. The complication rates observed in our study suggests that the endoscopic pituitary surgery is at least as safe as microscopic transphenoidal surgery. These rates were obtained with due experience and well-coordinated teamwork. To further improve these rates, new technological developments will be helpful.

Abstract
Among multimodality treatments for acromegaly, the goals of surgical intervention are to balance maximal tumor resection while preserving normal pituitary function and maintaining patient safety. The resection of growth hormone-(GH-) secreting pituitary adenomas in the hands of experienced surgeons results in hormonal remission in 50-70% of patients. Acromegalic patients often have medical comorbidities and anatomical variations complicating anesthesia and surgical management. Despite these challenges, complications such as CSF leak or new hypopituitarism following surgery remain uncommon. Over the past decade, endoscopic approaches to pituitary tumors have improved visualization and facilitated identification of additional tumor using angled telescopes. Patients with persistent acromegaly following surgery require continued medical and/or radiation-based interventions. The adjunctive use of stereotactic radiosurgery offers hormonal remission in 40-50% of patients. In this article, the current preoperative evaluation, indications for surgery, surgical approaches, role of radiosurgery, complications, and remission criteria following operative resection of GH adenomas are reviewed.
