Object. A wide variation in postoperative drainage volumes is observed during treatment of chronic subdural hematoma (CSDH) with twist-drill or burr-hole craniostomy and closed-system drainage. In this study the authors investigate the causes of the variation, the clinical significance thereof, and its influence on treatment outcome.Methods. A total of 175 cases were investigated between January 1991 and December 1997. Of these, 145 patients had surgery for CSDH, of whom 30 had bilateral lesions. The cases of CSDH were divided into five subtypes (low-density, isodense, high-density, mixed-density, and layering types) on the basis of the brain computerized tomography (CT) findings. Burr-hole craniostomies with closed-system drainage were performed in all patients and the drainage was maintained for 5 days, during which daily amounts of fluid were measured. The mean drainage volume over 5 days was 320 ml, with the largest volume (413 ml) seen in the low-density type and the smallest (151 ml) in the mixed-density type of CSDH. There were recurrences in six patients (seven instances, 4%). The mixed-density type had the highest recurrence rate (8.6%), whereas there was no recurrence for the low-density type. There were no recurrences in 81 patients in whom the total drainage volumes for 5 days were more than 200 ml, but there were recurrences in six (seven instances) of 94 patients in whom the total drainage volume was less than 200 ml.Conclusions. The postoperative drainage volumes varied greatly because of differences in the outer membrane permeability of CSDH, and such variation seems to be related to the findings on the CT scans obtained preoperatively. Patients with CSDH in whom there is less postoperative drainage than expected should be carefully observed, with special attention paid to the possibility of recurrence.

✓ A consecutive series of 32 adult patients with chronic subdural hematoma was studied in respect to postoperative cerebral reexpansion (reduction in diameter of the subdural space) after burr-hole craniostomy and closed-system drainage. Patients with high subdural pressure showed the most rapid brain expansion and clinical improvement during the first 2 days. Nevertheless, a computerized tomography (CT) scan performed on the 10th day after surgery demonstrated persisting subdural fluid in 78% of cases. After 40 days, the CT scan was normal in 27 of the 32 patients. There was no mortality and no significant morbidity. Our study suggests that well developed subdural neomembranes are the crucial factors for cerebral reexpansion, a phenomenon that takes at least 10 to 20 days. However, blood vessel dysfunction and impairment of cerebral blood flow may participate in delay of brain reexpansion. It may be argued that additional surgical procedures, such as repeated tapping of the subdural fluid, craniotomy, and membranectomy or even craniectomy, should not be evaluated earlier than 20 days after the initial surgical procedure unless the patient has deteriorated markedly.

✓ A simple method of bedside twist-drill craniostomy and closed-system drainage for evacuation of chronic and subacute subdural hematoma is introduced. The principles and theoretical considerations that form the basis for this technique are discussed. The technique was used in 21 patients with chronic or subacute subdural hematoma; it has produced results superior to those of the conventional methods used in our patient population. Possible mechanisms responsible for the better results with the simple twist-drill closed-system drainage are described.

Object. This study was conducted to determine the best position for the subdural drainage catheter to achieve a low recurrence rate after burr-hole irrigation and closed-system drainage of chronic subdural hematoma (CSDH).Methods. The authors studied 63 patients with CSDH in whom the drainage catheter tip was randomly placed and precisely determined on postoperative computerized tomography (CT) scans and 104 patients with CSDH in whom CT scans were obtained 7 days postsurgery. The location of the subdural drainage catheter, the maximum postoperative width of the subdural space, and the percentage of the ipsilateral subdural space occupied by air postoperatively were determined and compared with the postoperative recurrence and reoperation rates.Patients with parietal or occipital drainage had a higher rate of CSDH recurrence and much more subdural air than those with frontal drainage. In addition, patients with residual subdural air demonstrated on CT scans obtained 7 days postsurgery also had a higher recurrence rate than those without subdural air collections. Furthermore, patients with a subdural space wider than 10 mm on CT scans obtained 7 days postsurgery had a higher recurrence rate than those with a space measuring 10 mm or less.Conclusions. The incidence of postoperative fluid reaccumulation seems to be reduced by placing the tip of the drainage catheter in the frontal convexity and by removing subdural air during or after surgery.

✓ Although chronic subdural hematoma (CSDH) is a well-known entity, its recurrence rate has remained uncertain. There is little knowledge concerning whether the results of radiological imaging can be used to predict CSDH recurrence or whether surgical methods can influence this rate. The first aim of this study is to evaluate the relationship between the recurrence rate of CSDHs and their appearance on preoperative magnetic resonance (MR) or computerized tomography images. The second aim is to evaluate by means of a prospective randomized method the usefulness of closed-system drainage. From January 1988 through June 1996, the authors surgically treated 257 consecutive adult patients with CSDHs. Data obtained in 199 patients who were evaluated preoperatively by MR imaging were analyzed. Thirty-one of these patients underwent bilateral operations and thus 230 operative sites of CSDH were included in the analyses. The cases of CSDH were separated into high- and nonhigh-intensity groups on the basis of the appearance on T1-weighted MR images. From July 1992 to June 1996, the authors conducted a prospective randomized study on the recurrence rate of CSDH in patients undergoing burr-hole irrigation with or without closed system drainage. The recurrence rate of 3.4% in the high-intensity group was significantly lower than the 11.6% rate found in the nonhigh-intensity group (p < 0.05). The recurrence rates following irrigation with and without closed system drainage were significantly different (p < 0.025): 3.1% with closed system drainage and 17% following burr-hole irrigation alone. The surgical procedures were correlated with the MR findings. In the high-intensity group, 1.1% of CSDHs recurred in patients in whom closed system drainage was used and 11.1% in patients without closed system drainage. In the nonhigh-intensity group, 8.1% of CSDHs recurred in patients in whom drainage was used and 23.1% in patients without closed system drainage. Magnetic resonance T1-weighted imaging was useful in predicting the propensity of CSDHs to recur. Closed system drainage significantly reduced the recurrence rate of CSDHs regardless of MR findings.

Abstract A consecutive series of 21 adult patients with chronic subdural hematoma was studied in respect to postoperative resolution of subdural collections and clinical improvement after burr hole evacuation without subdural drainage. This series was compared to a previously studied series of patients with chronic subdural hematoma in whom postoperative closed system drainage had been installed. Using the identical protocol for treatment and postoperative follow-up, we obtained identical results with respect to time-related neurological improvement and persistence of subdural collections in the undrained and drained series, except that the steadily progressive clinical improvement during the early postoperative phase (24 hours) in all cases of the drained series was not universal in the undrained cases. Our study suggests that, to avoid the possibility of early postoperative clinical deterioration, burr hole craniostomy and closed system drainage is advisable. We think that subdural drainage is not necessary when the installation of the drainage system seems to be technically difficult, as it may be in cases with considerable perioperative cortical expansion.

Background: A chronic subdural hematoma (CSDH) is a collection of blood and blood breakdown products between the surface of the brain and its outermost covering the dura for more than 21 days. The elderly patients are more likely to develop a subdural hematoma, particularly from trivial trauma. CSDHs have been evacuated by burr holes, twist-drill craniotomies and craniotomies. The treatment of chronic subdural haematoma by burr hole drainage has been performed usually without using a closed drainage system, the problem of intracranial air entrapment still persists and can cause a deterioration in the level of consciousness or seizures in the postoperative period. We wanted to compare the effects of patient with drain and those without drain. Objectives: our study is to compare the clinical outcome of CSDH with or without drain. Methods: This prospective study was carried out at CMH Dhaka from January 2017 to July 2018; total 70 cases were investigated for the effectiveness of subdural drain. Cases were randomly allocated in two groups. Data were collected by specially designed questionnaire and analyzed by SPSS. Results and Observation: 70 patients of CSDH were included in this study out of which 25 underwent burr hole with closed system drainage and 45 underwent burr hole without closed system drainage. They were divided into Group A and B, respectively. Among the total number of patients 14 (20%) had shown recurrence. Out of 14 patients, 12 belong to Group B (86 %) and 2 belong to Group a (14 %). Conclusion: It is concluded that, those with a closed system drainage recurrence rate is significantly lower than with burr-hole evacuation alone. Bang. J Neurosurgery 2019; 9(1): 26-32

Subdural Tapping

✓ The cases of 30 infants with chronic subdural hematoma treated surgically between 1978 and 1987 (after the introduction of computerized tomography) were reviewed. This series was limited to infants presenting with increased intracranial pressure, neurological deficits, or developmental retardation. Nineteen patients were male and 11 were female, ranging in age from 1 to 14 months (average 6.1 months). The surgical treatment was initiated with percutaneous subdural tapping which was repeated periodically, if indicated, for 2 weeks. If the patients failed to respond to subdural tapping, subdural-peritoneal shunting was installed. The follow-up periods were from 3 months to 9 years 8 months (average 4 years 10 months). Computerized tomography at that time disclosed disappearance or minimal collection of subdural fluid in 28 cases (93%) and a significant collection (> 5 mm) in two (7%). Neurological examination revealed that the patients were “normal” in 17 cases (57%), “mildly or moderately disabled” in nine (30%), and “severely disabled” in four (13%). The majority of disabled patients had lesions secondary to infantile acute subdural hematoma, child abuse, or hemorrhagic diathesis. These results indicate that the treatment protocol in the present series is acceptable for the elimination of subdural hematoma. Together, early diagnosis and treatment of the etiological conditions causing the lesion are indispensable for obtaining a satisfactory neurological outcome.

✓ Eighteen patients with chronic subdural hematomas were studied by both brain scans and echoencephalography. All cases were verified by cerebral angiography. Brain scanning was accurate in predicting hematomas in 93% of the cases, and echoencephalography in 44%. When hematomas were bilateral or when frontal clots caused no shift in the diencephalic midline, the routine echoencephalogram often was negative. The two procedures are complementary, and serial studies may be helpful in the study of changing clinical situations.
