Dural Tears In Patients With Depressed Skull Fractures.

BACKGROUND: The presence of skull fracture in patients sustaining traumatic brain injury is an important risk factor for intracranial lesions. Assessment of integrity of dura in depressed skull fracture is of paramount importance because if dura is torn, lacerated brain matter may be present in the wound which needs proper debridement followed by water tight dural closure to prevent meningitis, cerebral abscess, and pseudomeningocoele formation. The objective of this study was to determine the frequency of dural tear in patients with depressed skull fractures. METHODS: This cross-sectional study was conducted at Department of Neurosurgery Ayub Teaching Hospital Abbottabad. All the patients of either patients above 1 year of age with depressed skull fracture were included in this study in consecutive manner. Patients were operated for skull fractures and per-operatively dura in the region of depressed skull fracture was closely observed for any dural tear. The data were collected on a predesigned pro forma. RESULTS: A total of 83 patients were included in this study out of which 57 (68.7%) were males and 26 (31.3%) were females. The age of the patients ranged from 1-50 (mean 15.71±13.49 years). Most common site of depressed skull fracture was parietal 32 (38.6%), followed by Frontal in 24 (28.9%), 21(25.3%) in temporal region, 5(6.0%) were in occipital region and only 1 (1.2%) in posterior fossa. Dural tear was present in 28 (33.7%) patients and it was absent in 55 (66.3%) of patients. CONCLUSIONS: In depressed skull fractures, there are high chances of associated traumatic dural tears which should be vigilantly managed.

Decompressive Craniectomy For Acute Subdural Haematoma With Expansile Duraplasty Versus Dural-Slits.

BACKGROUND: Traumatic subdural hematoma is one of the lethal injuries to brain. Various surgical techniques are used to evacuate the acute subdural hematoma. The hematoma evacuation can either be done by opening of dura by multiple slits or by opening of dura in single large c shape and then doing the expansile duraplasty. Present study aimed to compare both these techniques. METHODS: This randomized control study was conducted in department of neurosurgery, Ayub Medical College, Abbottabad from July 2011 to July 2013. A total of 59 patients were included in this study, which were randomly allocated in two groups (i.e., group A and group B) for decompressive craniectomy. Thirty-one patients were operated by craniectomy with full dural flap opening (Group A), and 28 patients were operated by craniectomy with multidural-slits (Group B). Glasgow Outcome score (GOS) at 6 weeks after the surgery was used to determine the outcome. RESULTS: Mean age of the patients was 33.4±12.8 years. Majority were males. In group A 51.6 % (16) of the patients survived out of which a favourable outcome (GOC 3-5) was observed in 41.9% of the patients, and 9.1% of patients ended up in vegetative state. While in group B 46.4% (13) of the patients survived among which favourable outcome was seen in 39.3% of patients and 7.1% of patients ended up in vegetative state. The difference in outcome measure is insignificant. CONCLUSIONS: There was no statistically significant difference among the two groups as regards the mortality, GOS, frequency of complications and hospital. While the duration of surgery was significantly shorter in patients operated with dural slits.

MICROVASCULAR DECOMPRESSION FOR TRIGEMINAL NEURALGIA.

BACKGROUND: Trigeminal Neuralgia (TGN) is the most frequently diagnosed type of facial pain. In idiopathic type of TGN it is caused by the neuro-vascular conflict involving trigeminal nerve. Microvascular decompression (MVD) aims at addressing this basic pathology in the idiopathic type of TGN. This study was conducted to determine the outcome and complications of patients with idiopathic TGN undergoing MVD. METHODS: In a descriptive case series patients with idiopathic TGN undergoing MVD were included in consecutive manner. Patients were diagnosed on the basis of detailed history and clinical examination. Retromastoid approach with craniectomy was used to access cerebellopontine angle (CP-angle) and microsurgical decompression was done. Patients were followed up for 6 months. RESULTS: A total of 53 patients underwent MVD with mean age of 51.6±4.2 years and male predominance. In majority of cases (58.4%) both Maxillary and Mandibular divisions were involved. Per-operatively superior cerebellar artery (SCA) was causing the neuro-vascular conflict in 33 (62.2%) of the cases, anterior inferior cerebellar artery (AICA) in 6 (11.3%) cases, both CSA and AICA in 3 (5.6%) cases, venous compressions in only 1 (1.8%) patient and thick arachnoid adhesions were seen in 10 (18.9%) patients. Postoperatively, 33 (68%) patients were pain free, in 14 (26.45%) patients pain was significantly improved whereas in 3 (5.6%) patients there was mild improvement in symptoms. Three (5.6%) patients did not improve after the primary surgery. Cerebrospinal fluid (CSF) leak was encountered in 7 (13.2%) patients post-operatively, 4 (7.5%) patients developed wound infection and 1 (1.8%) patient developed aseptic meningitis. Three (5.6%) patients had transient VII nerve palsy while one patient developed permanent VII nerve palsy. CONCLUSION: MVD is a safe and effective surgical option for treating patients with idiopathic TGN with better surgical outcome and fewer complications.

A ten year review of emergency peripartum hysterectomy in a tertiary care hospital.

BACKGROUND: Emergency peripartum hysterectomy (EPH) is a life saving procedure considered in cases of severe haemorrhage unresponsive to medical and conservative surgical procedures. The aim of present study was to review the frequency, indications, maternal morbidity and mortality associated with emergency peripartum hysterectomy in a tertiary care hospital in a developing country. METHODS: This was a cross sectional study in which data was retrospectively collected from January 2000 to December 2010. Main outcome measures were maternal morbidity and mortality associated with EPH. RESULTS: The incidence of EPH was 10.52/1000 deliveries. The main causes of EPH were rupture uterus 76 (34.86%), atonic uterus 65 (29.81%), placenta accreta 19 (8.71%), placenta previa 17 (7.7%), and placental abruption 36 (16.5%). Mostly subtotal hysterectomy was the preferred method done in 196 (89.9%) of cases, while total abdominal hysterectomy was done only in 22 (10.09%) of cases. The over all complication rate was 81.2% which included both minor and major complications like hypovolemic shock 180 (82.5%), febrile morbidity 108 (49.5%), wound infection 40 (18.3%), bladder injury 6 (2.75%), and thrombophlebitis 22 (10.09%). The maternal mortality in present review was (10.5%). CONCLUSION: Frequency of EPH was found to be high in this study. Obstetricians must be skilled in it particularly in developing countries where the main indication of hysterectomy is rupture uterus.
