Abstract
SIGNIFICANCE Surgical microscopes provide adjustable magnification, bright illumination, and clear visualization of the surgical field and have been increasingly used in operating rooms. State-of-the-art surgical microscopes are integrated with various imaging modalities, such as optical coherence tomography (OCT), fluorescence imaging, and augmented reality (AR) for image-guided surgery. AIM This comprehensive review is based on the literature of over 500 papers that cover the technology development and applications of surgical microscopy over the past century. The aim of this review is threefold: (i) providing a comprehensive technical overview of surgical microscopes, (ii) providing critical references for microscope selection and system development, and (iii) providing an overview of various medical applications. APPROACH More than 500 references were collected and reviewed. A timeline of important milestones during the evolution of surgical microscope is provided in this study. An in-depth technical overview of the optical system, mechanical system, illumination, visualization, and integration with advanced imaging modalities is provided. Various medical applications of surgical microscopes in neurosurgery and spine surgery, ophthalmic surgery, ear-nose-throat (ENT) surgery, endodontics, and plastic and reconstructive surgery are described. RESULTS Surgical microscopy has been significantly advanced in the technical aspects of high-end optics, bright and shadow-free illumination, stable and flexible mechanical design, and versatile visualization. New imaging modalities, such as hyperspectral imaging, OCT, fluorescence imaging, photoacoustic microscopy, and laser speckle contrast imaging, are being integrated with surgical microscopes. Advanced visualization and AR are being added to surgical microscopes as new features that are changing clinical practices in the operating room. CONCLUSIONS The combination of new imaging technologies and surgical microscopy will enable surgeons to perform challenging procedures and improve surgical outcomes. With advanced visualization and improved ergonomics, the surgical microscope has become a powerful tool in neurosurgery, spinal, ENT, ophthalmic, plastic and reconstructive surgeries.

Location-based treatment of intracranial aneurysms in moyamoya disease: a systematic review and descriptive analysis. Neurosurg Rev 2020; 44:1127-1139. [PMID: 32385590 DOI: 10.1007/s10143-020-01307-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Revised: 04/12/2020] [Accepted: 04/23/2020] [Indexed: 12/20/2022]
Abstract
We conducted a systematic review of the literature to evaluate the efficacy of various treatment modalities for intracranial aneurysms (IA) in patients with moyamoya disease (MMD) based on anatomical location of IA. A comprehensive review of studies documenting single cases or series of MMD patients with concomitant IA was conducted. Aneurysms were classified into two primary anatomical categories: those of the Circle of Willis (CoW) and those of peripheral "moyamoya" collateral vessels. Conservative, endovascular, and open surgical treatment modalities and their outcomes between each anatomical subgroup were descriptively compared. A total of 124 studies consisting of 275 patients with 313 IA were included. Of all IA, 59.6% were located on CoW vessels, 33.7% on peripheral vessels, and 6.7% in "other" locations. Of all CoW IA, 87.2% treated with endovascular techniques had no or minimal deficit at follow-up as compared with 56.7% of those treated with open surgery. Ninety-five percent of patients with peripheral aneurysms treated with endovascular therapy had no or minimal deficit, in contrast to open surgery (69.6%). Of peripheral IA treated conservatively with or without revascularization, 65.7% had spontaneous resolution as compared with 12.0% IA of the CoW. Our results support the use of endovascular techniques for direct treatment of both CoW and peripheral IA. Aneurysms of peripheral vessels respond well to indirect treatment through surgical revascularization as opposed to CoW aneurysms. The quality of evidence is limited due to heterogeneity of included studies and IA management in MMD patients should be considered in a case-specific manne.

Abstract
A peripheral cerebral aneurysm is known to develop at collateral vessels as a result of hemodynamic stress by the occlusion of the intracranial major arteries. We report a case of successful embolization of a ruptured aneurysm through a transdural anastomotic artery. The aneurysm formed at the developed collateral vessel from the meningeal branch of the occipital artery (OA) to the posterior pericallosal artery. A 59-year-old man presented with acute-onset headache, and computed tomography revealed subarachnoid hemorrhage and intracerebral hemorrhage at the splenium of the corpus callosum with intraventricular hemorrhage. Digital subtraction angiography demonstrated a ruptured aneurysm located at a transdural anastomotic artery from the right OA to the posterior pericallosal artery. The patient underwent endovascular treatment for the aneurysm through the transdural anastomotic artery with a coil and n-butyl-2-cyanoacrylate. Because it was impossible to navigate a microcatheter to the aneurysm through the right anterior cerebral artery because of the occlusion of its proximal portion, it was advanced through the transdural anastomosis from the right OA. The aneurysm was completely occluded without complications. Endovascular embolization is a useful treatment option for a peripheral cerebral aneurysm developed at a collateral vessel with intracranial major artery occlusion.

Abstract
A 77-year-old woman with arteriovenous shunt for hemodialysis in the left forearm suffered from subarachnoid hemorrhage due to the rupture of a saccular aneurysm located on the left lateral wall of vertebrobasilar junction. Her left subclavian artery was severely stenosed and subclavian steal phenomenon was demonstrated on the digital subtraction angiography. Embolization of the parent artery including the aneurysm using detachable coils resulted in the successful obliteration of the aneurysm through the revascularized left subclavian artery. This is the first case in which the vertebrobasilar junction aneurysm would be caused by the hemodynamic stress due to the subclavian steal phenomenon combined with the shunt for hemodialysis in the left forearm.

Abstract
Direct surgical intervention to treat ruptured basilar tip aneurysms in patients with moyamoya disease has rarely been attempted, and patients who have undergone such treatment have not fully recovered. We review six cases of surgically treated ruptured basilar tip aneurysm associated with moyamoya disease, including our own case to illustrate aspects of surgical intervention and the difficulties encountered. Patients who underwent surgery after 4 weeks of the onset of symptoms showed impressive results. Of the patients who underwent surgery in the acute stage, two died, including our patient, and one showed excellent recovery. It is emphasized that to achieve satisfactory surgical outcome, the following factors should be considered: (i) delayed operation is preferable, with extracranial-intracranial bypass in selected patients; (ii) careful preservation of moyamoyas and transdural collaterals is mandatory; (iii) intraoperative rupture of the aneurysm should be avoided; and (iv) using a neuroanaesthetic technique of induced hypothermia and hypertension may be preferable.

Abstract
Unruptured intracranial aneurysms (UIAs) are a major public health issue. These lesions have become increasingly recognized in recent years with the advent of advanced cerebral imaging techniques. Epidemiological evidence from multiple sources suggests that most intracranial aneurysms do not rupture. Therefore, it is desirable to identify which UIAs are at greatest risk of rupture when considering which to repair. It is important to compare size-, site-, and group-specific natural history rates with size-, site-, and age-specific morbidity and mortality associated with UIA repair because increased natural history risk often is associated with increased risk of aneurysm repair. Patient age is crucial in decision making because of its major effect on operative morbidity and mortality; however, it does not substantially affect natural history. The effect of age is most notable in patients about 50 years of age and older for open surgery and about 70 years of age and older for endovascular procedures. In general, rupture risk is lowest for patients in asymptomatic group 1 (no history of subarachnoid hemorrhage) with UIAs less than 7 mm in diameter in the anterior circulation. Surgical morbidity and mortality are most favorable for asymptomatic patients younger than 50 years who have UIAs less than 24 mm in diameter in the anterior circulation and no history of ischemic cerebrovascular disease. Endovascular morbidity and mortality may be less age dependent, and this could favor endovascular procedures, particularly in patients aged 50 to 70 years. An important issue is determining immediate vs long-term risk regarding treatment effectiveness and durability. This issue emphasizes the importance of long-term follow-up in patients after surgical and endovascular procedures.

Abstract
✓ Almost 50 years of research on moyamoya disease (1957–2006) has led to the development of a variety of surgical and medical options for its management in affected patients. Some of these options have been abandoned, others have served as the basis for the development of better procedures, and many are still in use today. Investigators studying moyamoya disease during this period have concluded that the best treatment is planned after studying each patient's presenting symptoms and angiographic pattern.
The surgical procedures proposed for the treatment of moyamoya disease can be classified into three categories: direct arterial bypasses, indirect arterial bypasses, and other methods. Direct bypass methods that have been proposed are vein grafts and extracranial–intracranial anastomosis (superficial temporal artery–middle cerebral artery [STA–MCA] anastomosis and occipital artery–MCA anastomosis). Indirect techniques that have been proposed are the following: 1) encephaloduroarteriosynangiosis; 2) encephalomyosynangiosis; 3) encephalomyoarteriosynangiosis; 4) multiple cranial bur holes; and 5) transplantation of omentum. Other options such as cervical carotid sympathectomy and superior cervical ganglionectomy have also been proposed. In this paper the authors describe the history of the development of surgical techniques for treating moyamoya disease.

Abstract
Four patients presented with familial intracranial aneurysms and familial moyamoya disease, including one patient with both familial intracranial aneurysm and moyamoya disease. Basilar bifurcation aneurysms were present in two patients, moyamoya disease in one, and both basilar bifurcation aneurysm and moyamoya disease in one. These events are most likely to arise from different genetic abnormalities associated with basilar bifurcation aneurysm and moyamoya disease.

Abstract
The authors describe the case of a patient with a symptomatic giant aneurysm of the posterior communicating artery (PCoA) associated with bilateral idiopathic occlusion of the internal carotid artery (ICA). The presence of severe tortuosity of the vertebral arteries (VAs), both at their origin from the subclavian artery and at the level of the third segment, impeded navigation of the catheter for embolization of the aneurysm with Guglielmi detachable coils (GDCs). A direct surgical approach was considered to be a high-risk procedure because of the bilateral occlusion of the ICAs and the size of the aneurysm. The following therapeutic strategy was therefore adopted: 1) balloon occlusion test of the left VA; 2) vertebro-vertebral bypass with saphenous vein graft to provide a pathway for subsequent embolization; 3) ICA-left middle cerebral artery bypass to ensure blood flow in the event that embolization resulted in closure of the PCoA; and 4) GDC embolization of the aneurysm via the posterior circulation graft to ensure complete exclusion of the lesion from the arterial circulation and preservation of the PCoA. At 3-month follow-up review the patient did not present with any neurological deficits; at 1-year control examination, magnetic resonance (MR) imaging and MR angiography both confirmed complete exclusion of the aneurysm and patency of the two bypasses.

Abstract
We describe a patient with moyamoya disease associated with an unruptured basilar tip aneurysm which was treated by endovascular embolization using Guglielmi detachable coils (GDCs). A 53-year-old man presented with left hemiparesis persisting for 3 mon ths before admission. Cerebral angiography revealed occlusion of the bilateral middle cerebral arteries and the left anterior cerebral artery, stenosis of the right anterior cerebral artery, and basal moyamoya vessels. In addition, a saccular small aneurysm was seen at the top of the basilar artery. The aneurysm was completely embolized by intraaneurysmal GDCs. Direct surgical clipping is often selected for the treatment of posterior fossa aneurysms in moyamoya disease. However, complete clipping is usually difficult due to the difficulties in operative technique associated with moyamoya disease. We suggest that the endovascular treatment using GDCs is comparatively safe and effective for the treatment of surgically difficult aneurysms in patients with moyamoya disease.

Abstract
A 58-year-old female was admitted unconscious to a local hospital. Computed tomography demonstrated subarachnoid hemorrhage. Cerebral angiography revealed evidence of moyamoya disease and a saccular aneurysm at the tip of the basilar artery. The patient was transferred to our hospital for embolization of the basilar tip aneurysm. Endovascular embolization was performed using Guglielmi detachable coils (GDCs), and the aneurysm was completely occluded with preservation of the parent artery. No change in the patient's neurological status was seen during and after the procedure. Endovascular treatment using GDCs appears to be particularly suitable for ruptured cerebral saccular aneurysms in patients with moyamoya disease.

Abstract
BACKGROUND Aneurysms of the posterior circulation are challenging lesions to neurosurgeons, despite improvements in microsurgical techniques and advances in skull base approaches. We present a rare case of a posterior cerebral artery (PCA)-posterior communicating artery (PcomA) junction aneurysm associated with bilateral internal carotid artery (ICA) occlusion successfully treated with an endovascular procedure. CASE DESCRIPTION A 57-year-old female presented with sudden onset of severe headache and loss of consciousness. CT scan showed diffuse subarachnoid hemorrhage and acute hydrocephalus. The patient developed severe neurogenic pulmonary edema and shock. Although her neurogenic pulmonary edema did not resolve, she recovered from shock. However, her general condition was so critical and her vital signs so unstable, that direct surgery under general anesthesia was considered too risky. A cerebral angiogram showed complete occlusion of both internal carotid arteries without any Moyamoya vessels. A saccular aneurysm located at the right PCA-PcomA junction was seen. To obliterate the aneurysm and prevent rerupture, the patient underwent coil embolization via an endovascular approach under sedation with local anesthesia. The balloon remodeling technique was useful to prevent occlusion of parent arteries. Finally, four interlocking detachable coils (IDC) with a total length of 44 cm were used to completely obliterate the aneurysm using the balloon remodeling technique. The patient made a full recovery after treatment and the aneurysm remained obliterated 2 years after coil embolization. CONCLUSIONS We emphasize the advantages of the endovascular approach for the patient in critical condition. We believe that this is the first report of a PCA-Pcom junction aneurysm associated with bilateral ICA occlusion without moyamoya disease.

Abstract
Moyamoya disease is often accompanied by intracranial major artery aneurysms in the posterior circulation which acts as collateral channels in place of the stenotic internal carotid arteries. These major artery aneurysms are considered to have high risk of enlargement and rupture due to increased hemodynamic stress. Direct surgical intervention has been recommended for the treatment of these aneurysms, but the direct approach to them is often difficult due to interference by intertwined abnormal vessels. We have performed direct surgery for seven major artery aneurysms in five patients with Moyamoya disease. Of these three aneurysms located in the anterior circulation were successfully clipped via pterional or interhemispheric approach. Of four posterior circulation aneurysms (two at the junction of the basilar artery and the superior cerebellar artery and two at the P1-P2 junction of the posterior cerebral artery), one was approached via pterional route because collateral vessels in the basal cistern was judged not to be rich on angiograms. However, the operative field was interfered by abundant fragile collateral vessels and it was difficult to reach the distal portion of the basilar artery. In contrast, in the other three cases in which the subtemporal approach was employed, there weren't any problems in exposures of the aneurysms. Our experiences indicate that subtemporal approach is superior than the pterional approach to reach the distal portion of the basilar artery in patients with Moyamoya disease.

Abstract
A retrospective analysis of 111 patients with aneurysms associated with Moyamoya disease is presented. The subjects comprised of our 12 cases and 99 other well-documented cases. These 111 cases had 131 aneurysms. There were 48 males and 63 females. The average age was 40.3 years. The clinical manifestations were intracranial haemorrhage in 99 cases (89%), and ischaemic events in 9 cases (8%), but no mention was made of these in the last three cases (2%). The Hunt and Kosnik grades were grade 1 in 8%, grade 2 in 23%, grade 3 in 31%, grade 4 in 35%, and grade 5 in 3%. Of the 131 aneurysms, 73 (56%) were found distributed around the circle of Willis, 24 (18%) in the basal ganglia, 29 (22%) on collateral vessels, and 5 (4%) on other vessels. Forty-six percent of the cases were treated surgically, 51% conservatively, and 3% by endovascular procedures. The surgical procedures for the aneurysms were; neck clipping in 49%, aneurysmectomy in 18%, wrapping of the aneurysm in 11%, coating or cautery of the aneurysm in 7%, and revascularization only in 11%. The outcomes were Glasgow Outcome Scale 1 in 30%, 2 in 22%, 3 in 11%, 4 in 1%, and 5 in 25%. The main reasons for the unfavourable outcome were initial poor clinical grade and rebleeding. Follow-up angiography of 25 aneurysms demonstrated that all aneurysms in the basal ganglia or on the collateral vessels disappeared. We recommend surgical intervention for aneurysms associated with Moyamoya disease to prevent rupture or rebleeding, especially for aneurysms around the circle of Willis. However, direct surgery is not recommended for aneurysms found in the basal ganglia or on the collateral vessels.

Abstract
We evaluated and analysed our own 31 cases of the haemorrhagic type of moyamoya disease to clarify the clinical features of this disease. The cases were divided into three groups. Group A consisted of 12 cases with aneurysms. Aneurysms on the circle of Willis were treated as ordinary saccular aneurysms. Group B consisted of 14 cases with intracerebral haemorrhage (ICH) without aneurysms. These were managed almost as spontaneous ICH. Group C consisted of 5 cases with intraventricular haemorrhage (IVH) without aneurysms or ICH. Twenty-two surgical procedures for aneurysms, ICH and IVH were done in 19 cases (62%). Nineteen procedures for preventing future strokes were undertaken in 11 cases (35%). The overall initial outcome was excellent in 12 cases (39%), good in 7 cases (23%), poor in 7 cases (23%), and death in 5 cases (15%). During the follow-up period (mean: 6.5 years), rebleeding occurred in two cases (8%), and ischaemic attacks in two cases (8%). The rate of rebleeding or ischaemic attacks was 1.19% per patient-year during the follow-up period. There was no ischaemic or rebleeding episode in cases treated by STA-MCA bypass with encephalomyosynagiosis (EMS) during the follow-up period. Management of the primary haemorrhage should be according to the clinical condition, type of haemorrhage, and source of haemorrhage. When the patient needs to undergo revascularization surgery to prevent future strokes, we recommend STA-MCA bypass with EMS instead of encephaloduro-arteriosynangiosis (EDAS).

Abstract
Transcranial Doppler sonography was performed on eight patients diagnosed as Moyamoya disease. Angiographically, the patients-four adults (mean age 42) and four children (mean age 7.7)-underwent a complete six- or five-vessel angiographic study. The results showed the following: (1) Despite the presence of stenosis, all middle cerebral arteries showed very low-flow velocity compared to their ipsilateral distal internal carotid arteries. In adult cases, the difference was very significant (p < 0.02). (2) Relatively high-flow velocity was observed in the posterior cerebral arteries of children, and in the ophthalmic arteries of adult cases. (3) In several occasions, very low-flow velocity values were still detected despite the fact that with angiography, the respective arterial segments were hardly opacified. The relation and discrepancy between these results and the angiographic findings, and the potential application of transcranial doppler in assessing and grading the severity of moyamoya disease are discussed.

Abstract
Three patients are reported with the rare combination of moyamoya disease and features of an associated arteriovenous malformation. Two of the patients developed ischemic symptoms, and the third patient presented with an intracerebral hemorrhage. All three patients fit the criteria of a stage III moyamoya syndrome on the basis of the angiographic classification described by Suzuki and Takaku. The patients were referred to this medical center following angiography with the presumptive diagnosis of arteriovenous malformation.

Abstract
Moyamoya disease is a rare neurovascular condition that affects both children and adults. Increasingly these patients present for surgical management to improve the cerebral circulation since medical therapy is essentially ineffective. Because of the precarious cerebral circulation, these patients represent an anaesthetic challenge. In this report we review the pathophysiology of moyamoya disease, summarize our experience with seven patients and discuss the anaesthetic management.

Abstract
We report a 6-year-old girl with an intracranial aneurysm associated with moyamoya disease. The patient did not have a subarachnoid hemorrhage but had an ischemic attack. The aneurysm, located on the proximal portion of the lateral posterior choroidal artery, disappeared after external carotid-internal carotid anastomosis. The characteristics of the aneurysms associated with moyamoya disease are briefly reviewed. We emphasize that the treatment of choice in moyamoya disease is cerebral revascularization, because it reduces the increased blood flow through the moyamoya vessels, basilar artery and other uninvolved cerebral arteries, the sites where the aneurysms in this disease frequently develop, as the blood flow through the external carotid system is increased by such an operation.
