Background: During aneurysm microsurgery, the aneurysmal sac is excluded from circulation by placing one or more clips at the base of the aneurysm. In some cases of complex aneurysms or subarachnoid hemorrhage history, transient clipping before definitive clipping is necessary. The closing force of the transient clip is less than the permanent clip; however, it is sufficient to stop circulation to the aneurysmal sac. The aim of the following work is to analyze and describe histological changes caused by transient and permanent clipping of the abdominal aorta in Wistar-type rats, to study the correlation between the closing force of the clip and the time, it remains on the vascular tissue structures. Methods: Six groups were formed, with 10 rats each, whereby temporary clipping of the abdominal aorta was performed with subsequent sampling of the site where the vascular clip was placed. The groups were: control and temporary clipping with: 2, 5, 10, and 15 and permanent clipping with 5 min. Results: Resection samples of the 3 μm thick aorta were obtained through the routine histological technique and special histochemical techniques (Masson’s Trichrome and orcein) from the six groups. Transmural changes were found from Group II–VI. Conclusion: There is a vascular histological effect after both transient and permanent clipping. The sum of time and strength of the clip induce vascular changes visible at 5 min.

“…Most of the papers showed that a partial surgical excision provides for seizure control only for a limited period of time [ 64 ]. Compared with extracranial malformation, the ligation of the affluent artery affected by the malformation is sufficient to decrease the flow of the lesion and the depletion of the mass of the malformation [ 71 ].…”

“…Although there is a debate between the choice of a surgical approach or sclerotherapy and embolization as the first lines of treatment, there is agreement on the need to adequately characterize the lesions in order to determine the most appropriate management, guided by clinical data, imaging, and histopathological data. The data are mainly gathered during the transoperative period that is associated with the delimitation of resection sites [ 44 , 71 , 78 , 80 , 83 , 84 ].…”

Vascular malformations are frequent in the head and neck region, affecting the nervous system. The wide range of therapeutic approaches demand the correct anatomical, morphological, and functional characterization of these lesions supported by imaging. Using a systematic search protocol in PubMed, Google Scholar, Ebsco, Redalyc, and SciELO, the authors extracted clinical studies, review articles, book chapters, and case reports that provided information about vascular cerebral malformations, in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 385,614 articles were grouped; using the inclusion and exclusion criteria, three of the authors independently selected 51 articles about five vascular cerebral malformations: venous malformation, brain capillary telangiectasia, brain cavernous angiomas, arteriovenous malformation, and leptomeningeal angiomatosis as part of Sturge–Weber syndrome. We described the next topics—“definition”, “etiology”, “pathophysiology”, and “treatment”—with a focus on the relationship with the imaging approach. We concluded that the correct anatomical, morphological, and functional characterization of cerebral vascular malformations by means of various imaging studies is highly relevant in determining the therapeutic approach, and that new lines of therapeutic approaches continue to depend on the imaging evaluation of these lesions.

“…For instance, the evaluation of DECRA (Decompressive Craniectomy in Patients with Severe Traumatic Brain Injury) through RESCUEicp (Randomized Evaluation of Craniectomy Surgery for Uncontrollable Elevation of Intracranial Pressure) and RESCUE-ASDH (Randomized Evaluation of Craniectomy Surgery for Patients undergoing acute subdural hematoma evacuation) has shown increased rates of disability in survivors after traditional DC. 5 Therefore, articulated craniotomy (HC), also called "hinge" or "floating" type, is presented as an alternative to traditional DC. This surgical technique enables adequate decompression and reduction of intracranial pressure while eliminating the need for a secondary cranioplasty, with improved outcomes anticipated (Table 1).…”

A 38-year-old male patient with multiple skull injuries caused by a small-caliber firearm projectile whose entry hole was the right eye after being attacked when leaving his home. Consequently, he presented head trauma with multifragmented fracture of the cranial vault causing exposure of the brain mass in the bilateral frontoparietal region and complete injury to the right eyeball with fracture of the orbit in its posterior, lateral, medial, roof and floor walls. He was transferred to the General Hospital of Axapusco, where the patient was received with 8 points on the Glasgow scale and a simple tomography of the skull was performed, observing injury to both hemispheres, bilateral subarachnoid hemorrhage, parasagittal hemorrhagic contusions and cerebral edema, predominantly affecting to the corpus callosum and cingulum. Therefore, hinge-type decompressive craniectomy and debridement in the first 12 hours of trauma were determined as surgical treatment. It should be noted that a favorable recovery was obtained without associated complications. It is concluded that the surgical treatment of choice is early decompressive craniectomy when the patient presents less than 9 points on the Glasgow Coma Scale at admission, the injury along the path of the wound is bihemispheric and posterior fossa, the time that elapses from the injury to the performance of the surgery is within the first 12 hours, there is pupillary reactivity and the age of the patient is greater than 35 years.
