“…19 The primary hemodynamic alteration observed in APH is an increase in afterload (systemic vascular resistance [SVR], systolic blood pressure [SBP], and diastolic blood pressure [DBP]), with or without tachycardia; there is no difference in cardiac index, left ventricular stroke volume, or left atrial pressure compared with normotensive patients. 8,11,[24][25][26][27] These findings are consistent with a predominant sympathetic-mediated rise in MAP secondary to vasoconstriction. Many preoperative patient characteristics and operative factors may be associated with an increased risk of APH, and several postoperative factors may precipitate increased sympathetic activity, and therefore cause or aggravate APH.…”

Introduction Between 20-50% of neurosurgical patients may develop early perioperative complications, and 25% have more than one clinical complication. The most commons are high blood pressure (25%) and cardiovascular events (7%). Intraoperative hypertension is characterized by an increase of 20% in basal blood pressure. Objectives The aim of this paper is to review and discuss the pathophysiology, diagnosis and treatment of perioperative hypertension in patients undergoing neurosurgery, and to propose one table with therapeutic options. Methods A review using Scielo, PubMed, Ebsco and Artmed databases with inclusion and exclusion criteria. Articles published from 1957 to 2015 were selected. Discussion Five factors were established as causes: arterial hypertension, clinical conditions, surgical procedures, and operative and anesthetic factors. Specific causes preoperative, intraoperative and posoperative. The pathophysiology may have some relationship with catecholamines and sympathetic nervous system stimulation. Conclusion Perioperative hypertension in neurosurgery may have many causes, some of them recognizable and preventable. This increased pressure may be associated with intracranial hematomas in some cases. The recognition and treatment of this disease can be helpful in the management of the postoperative period.

“…We believe that slow and progressive elongation through external fixation helps avoid the sudden stretching of the sympathetic nerves located around the blood vessels, which are believed to be the main etiology of this complication [36,37]. We observed pin track infections in 69% of our cases, which is not very different from the percentage (between 30 and 83%) reflected in the bibliography [28][29][30]32].…”

There were no superficial or deep infections, and no fractures or distal sensory-motor alterations. There was one case of arthrodiatasis of the knee (6.3%) which was resolved when the fixator was removed, and 11 cases of pin-track infection (68.7%) which were resolved with local care and oral antibiotics. To conclude, spastic knee flexion contracture can be treated gradually with monolateral external fixator with distraction devices, and with distraction modules which prevent acute stretching of the posterior neurovascular structures of the knee.

An adolescent boy with spastic diplegic cerebral palsy presented with crouch gait. He had bilateral severe flexion deformities of knees and hips. He was treated with single event multilevel surgery for the correction of deformities. Surgical procedures included bilateral adductor release, iliopsoas lengthening, bilateral femoral shortening and patella plication. Persistent hypertension was noted in the post-operative period. All causes of secondary hypertension were ruled out. Having persistent hypertension following the femoral shortening procedure is unusual. Antihypertensive medication controlled his blood pressure 15 months after surgery. Hypertension following correction of knee flexion deformity and limb lengthening is well known. Hypertension has not been described with the shortening osteotomy of the femur. Hypertension is a rare complication following the corrective surgery for the treatment of crouch gait. Blood pressure should be monitored during the post-operative period to detect such a rare complication.
