Type Of Surgery

Hemostatic options available to the surgeon in the late 19th and early 20th centuries were limited. The surgical ligature was limited in value to the neurological surgeon because of the unique structural composition of brain tissue as well as the approaches and operating angles used in this type of surgery. In this manuscript the authors review the options available and the evolution of surgical hemostatic techniques and electrosurgery in the late 19th and early 20th centuries and the impact of these methods on the surgical management of tumors of the brain and its coverings.

Abstract BACKGROUND Sonoelastography is an ultrasound imaging technique able to assess mechanical properties of tissues. Strain elastography (SE) is a qualitative sonoelastographic modality with a wide range of clinical applications, but its use in brain tumor surgery has been so far very limited. OBJECTIVE To describe the first large-scale implementation of SE in oncological neurosurgery for lesions discrimination and characterization. METHODS We analyzed retrospective data from 64 patients aiming at (i) evaluating the stiffness of the lesion and of the surrounding brain, (ii) assessing the correspondence between B-mode and SE, and (iii) performing subgroup analysis for gliomas characterization RESULTS (i) In all cases, we visualized the lesion and the surrounding brain with SE, permitting a qualitative stiffness assessment. (ii) In 90% of cases, lesion representations in B-mode and SE were superimposable with identical morphology and margins. In 64% of cases, lesion margins were sharper in SE than in B-mode. (iii) In 76% of cases, glioma margins were sharper in SE than in B-mode. Lesions morphology/dimensions in SE and in B-mode were superimposable in 89%. Low-grade (LGG) and high-grade (HGG) gliomas were significantly different in terms of stiffness and stiffness contrast between tumors and brain, LGG appearing stiffer while HGG softer than brain (all P < ·001). A threshold of 2.5 SE score had 85.7% sensitivity and 94.7% specificity in differentiating LGG from HGG. CONCLUSION SE allows to understand mechanical properties of the brain and lesions in examination and permits a better discrimination between different tissues compared to B-mode. Additionally, SE can differentiate between LGG and HGG.

Abstract INTRODUCTION Postoperative ischemia is a frequent phenomenon in patients with brain tumors and is associated with postoperative neurological deficits and impaired overall survival. Previous clinical and experimental studies have shown that the application of a brief ischemic stimulus not only in the target organ but also in a remote tissue can prevent ischemia. We hypothesized that remote ischemic preconditioning (rIPC) in patients with brain tumors undergoing elective surgical resection reduces the incidence of postoperative ischemic tissue damage and its consequences. METHODS Sixty patients were randomly assigned to two groups, with 1:1 allocation, stratified after tumor type (glioma or metastasis) and previous treatment with radiotherapy. Remote ischemic preconditioning was induced by inflating a blood pressure cuff placed on the upper arm three times for 5 minutes at 200 mmHg in the treatment group after induction of anesthesia. Between the cycles, the blood pressure cuff was released to allow reperfusion. In the control group no preconditioning was performed. Early postoperative MR images were evaluated blinded to randomization for the presence of ischemia and its volume. RESULTS >Fifty-eight of the 60 patients were assessed for occurrence of postoperative ischemia. Of these 58 patients, 44 (75.9%) had new postoperative ischemic lesions. The incidence of new postoperative ischemic lesions was significantly higher in the control group (87.1%) (27/31) than in the rIPC group (63.0%) (17/27) (P = 0.03). The median infarct volume was 0.36 cm3 (IR: 0.0- 2.35) in the rIPC group compared with 1.30 cm3 (IR: 0.29- 3.66) in the control group (P = 0.09). CONCLUSION Application of rIPC significantly reduced the incidence of postoperative ischemic tissue damage in patients undergoing elective brain tumor surgery. This is the first study indicating a benefit of rIPC in brain tumor surgery.

Abstract BACKGROUND AND IMPORTANCE: Disseminated intravascular coagulation is a relatively common complication in patients with trauma, sepsis, obstetric calamities, and certain malignancies. We report a rare case of DIC after embolization and surgery for a large meningioma. We also review the literature on coagulopathy during brain tumor surgery as well as the diagnosis and treatment of this complication. CLINICAL PRESENTATION: A 62-year-old woman presented with a 3-week history of aphasia, difficulty with handwriting, personality change, and right-sided weakness. Magnetic resonance imaging demonstrated a 6.3 × 5.4-cm multilobe and avidly enhancing mass within the left frontal region. The patient underwent preoperative transcatheter Onyx embolization of the tumor, followed immediately by craniotomy for resection of the tumor. Surgery was complicated by coagulopathy leading to substantial blood loss. The diagnosis of disseminated intravascular coagulation was established by intraoperative thromboelastography, after which the patient was treated with replacement therapy, Amicar, and modest hypotension. One year after surgery, the patient had fully recovered and had no focal neurological deficit. CONCLUSION: This case report adds to the few reported cases of disseminated intravascular coagulation as a complication of brain tumor surgery. This patient's successful outcome may be attributed to timely recognition of the condition and effective, prompt treatment.
