Role Of Intra-Operative Ultrasound In Brain Tumour Surgeries, Mohammad Hamza Bajwa, Saqib Kamran Bakhshi, Muhammad Shahzad Shamim May 2021

Role Of Intra-Operative Ultrasound In Brain Tumour Surgeries, Mohammad Hamza Bajwa, Saqib Kamran Bakhshi, Muhammad Shahzad Shamim

Section of Neurosurgery

The use of intra-operative ultrasound remains a largely underutilized option in brain tumour surgeries. The widespread availability of neuronavigation may be the reason why such a useful modality has become less popular even though recent advances in ultrasound technology have greatly improved its utility. The available literature also clearly shows that it offers additional advantages especially when used with neuronavigation. Herein the authors have briefly touched upon the available literature on the role of intraoperative ultrasound in brain tumour surgeries.

Department of Neurosurgery Posters

Spinal arachnoiditis (SA) is an extremely rare and delayed complication of intracranial subarachnoid hemorrhage (SAH). SA is an inflammatory process leading to chronic fibrosis of the spinal cord. Possible pathophysiology is a two-staged disease of initial inflammatory reaction secondary to SAH, followed by a “free interval phase” prior to delayed adhesive phase (i.e. SA). The clinical course can be complicated and is the cause of major morbidity.

Section of Neurosurgery

Robotic surgery has been the forte of minimally invasive stereo-tactic procedures for some decades now. Ongoing advancements and evolutionary developments require substantial evidence to build the consensus about its efficacy in the field of neurosurgery. Main obstacle in obtaining successful results in neurosurgery is fine neural structures and other anatomical limitations. Currently, human rationalisation and robotic precision works in symbiosis to provide improved results. We reviewed the current data about recent interventions. Robots are capable of providing virtual data, superior spatial resolution and geometric accuracy, superior dexterity, faster manoeuvring and non-fatigability with steady motion. Robotic surgery also allows simulation of …

Delayed Spinal Cord Infarction Following Anterior Cervical Surgical Decompression, Muhammad Faheem Khan, Rashid Jooma, Fauzan Alam Hashmi, Muhammad Faraz Raghib

Section of Neurosurgery

Anterior cervical discectomy and fusion (ACDF) for cord compression is a safe and effective procedure with good outcomes. However, worsening of myelopathy is the most feared adverse event of the surgery. We report the case of a 36-year-old male patient who presented with an acute non-traumatic C5-6 cervical disc herniation causing incomplete quadriparesis. He underwent an uncomplicated ACDF at C5-6, and after an initial period of improvement, he developed a delayed onset of an anterior cord syndrome on day 3, without any discerning cause. We have reviewed similar cases reported in the literature and believe that our patient's postsurgical course …

Malignant Peripheral Nerve Sheath Tumor (Mpnst): An Overview With Emphasis On Pathology, Imaging And Management Strategies., Timothy C. Beer

Timothy C Beer

MPNSTs are rare malignancies that are classically associated with pre-existing plexiform neurofibromas in neurofibromatosis type 1 (NF-1) patients, but also occur in association with radiation as well as sporadically in patients with no known risk factors. The typical presentation of sporadic MPNST is a new painless enlarging mass. The typical presentation of MPNST in an NF-1 patient is rapid enlargement or new onset of pain associated with a pre-existing plexiform neurofibroma. Although both MPNST and benign neurofibromas share in common the absence of neurofibromin function due to loss of both NF-1 alleles, malignant transformation to MPNST requires several additional aberrations, …

Role Of Neurosurgery In The Management Of Stroke, Gohar Javed, Muhammad Zubair Tahir, Ather Enam

Section of Neurosurgery

Stroke is the second leading cause of death worldwide. The aim of treatment in stroke patients is to prevent further neurologic deterioration and prevent recurrence. Despite all advances in medical treatment, morbidity and mortality in stroke patients is still very high. The other alternative is surgical treatment, which still lacks class 1 evidence. However there is recent reconsideration of this form of treatment and ongoing trials are showing some promising results. In this review the recent advances in surgical treatment of stroke will be discussed along with recommendations from the latest randomized trials.
