Water Hammer Effect

Vertebrobasilar dolichoectasia is a clinical entity associated rarely with obstructive hydrocephalus. We present a 48-year-old male with a profound dilatation of the ventricular system due to a dolichoectatic basilar artery, as appeared in imaging studies. The patient suffered from longstanding hydrocephalus and presenile dementia. The underlying mechanism for obstructive hydrocephalus due to vertebrobasilar dolichoectasia is considered to be both a <em>water-hammer effect</em> and a direct compression of adjacent structures. We suggest prompt surgical intervention upon diagnosis as a first choice treatment in order to avoid further complications.

AbstractSurgical intervention for umbilical diseases in calves, when indicated, is a complementary and indispensable therapeutic resource for the treatment of umbilical conditions and is commonly performed using celiotomy. However, laparoscopy has demonstrated feasibility in many diagnostic and therapeutic procedures. The aim of this study was to assess the feasibility of the techniques and the surgical time of laparoscopy and celiotomy used in intra-abdominal resection of the umbilical vein and urachus of bovine fetuses (cadavers). Resection of the umbilical vein and urachus using laparoscopy and celiotomy was performed in 26 anatomical specimens (bovine fetuses obtained from an official slaughterhouse). Resection of umbilical structures was feasible with both techniques, but shorter surgical time and minimal tissue damage were achieved using laparoscopy. Laparoscopy requires specialized training and appropriate instruments and is an important tool for diagnostic and therapeutic exploration of the umbilical structures, liver, bladder, and associated/adjacent structures.

Background Thoracic outlet syndrome is described as a group of distinct disorders producing signs and symptoms attributed to compression of nerves and blood vessels in the thoracic outlet region. Purpose To describe the exercise-induced scalenus anticus syndrome attributed to the anterior scalenus hypertrophy as a thoracic outlet syndrome underlying mechanism and to give recommendations for a safe and effective surgical treatment. Study Design Case series; Level of evidence, 4. Methods Twelve young professional athletes admitted for thoracic outlet syndrome (8 cases of neurologic thoracic outlet syndrome, 4 cases of mixed neurologic and vascular thoracic outlet syndrome) who reported numbness, tingling, early fatigue, muscle weakness, and pain were enrolled in the study. Scalenus hypertrophy was suspected to be the causative factor. Scalenectomy was performed in all cases. Results All patients had moderate to severe hypertrophy of the anterior scalenus muscle. Scalenectomy was performed, and there were no intraoperative or postoperative complications. Full activity was quickly achieved, and no recurrence of symptoms was documented. Conclusion Surgical intervention for scalenus anticus syndrome can allow an athlete to return to full activity and improve quality of life. Surgical intervention seems to be the treatment of choice in terms of restoring quality of life and physical activity.

Paranasal sinus mucocele is a slowly growing benign cystic lesion. It usually involves the frontal and ethmoid sinuses and can extend to adjacent structures, especially to the orbit, skull base and brain parenchyma. Prompt surgical intervention is needed when symptoms occur. Complete resection of mucocele is approached via endoscopic sinus surgery, while marsupialization is also widely considered. Recently, we encountered a case of spontaneous brain herniation and cerebrospinal fluid leakage during endoscopic marsupialization of ethmoid sinus mucocele. Herein, we report the case with a review of the literature.

Epignathus is a rare congenital orofacial teratoma that arises from the sphenoid region of the palate or the pharynx. It occurs in approximately 1:35,000 to 1:200,000 live births representing 2% to 9% of all teratomas. We present the case of a newborn of 39.4 weeks of gestation with a tumor that occupied the entire oral cavity. The patient was delivered by cesarean section. Oral resection was managed by pediatric surgery. Plastic surgery used virtual 3-dimensional models to establish the extension, and depth of the tumor. Bloc resection and reconstruction of the epignathus were performed. The mass was diagnosed as a mature teratoma associated with cleft lip and palate, nasoethmoidal meningocele that conditions hypertelorism, and a pseudomacrostoma. Tridimensional technology was applied to plan the surgical intervention. It contributed to a better understanding of the relationships between the tumor and the adjacent structures. This optimized the surgical approach and outcome.

Abstract Introduction Some neurosurgeons believe that doing a trephine craniotomy (TC) decreases the chance of recurrence in chronic subdural hematoma (cSDH). But this is not supported by any evidence. Methods A retrospective analysis of patients who were operated for cSDH from 2014 to 2019 at our institute was done. Factors causing recurrence were studied. Results A total of 156 patients were operated in the given period, among which 88 underwent TC and 68 patients underwent burr hole drainage (BHD) for evacuation of cSDH. All patients underwent two trephines or two burr holes placed according to the maximum thickness of the hematoma. Rate of recurrence in trephine group was 12.5% and in burr-hole group was 11.76% and was not statistically significant. Significant factors for recurrence included nontraumatic cSDH, anticoagulant use, presence of membranes, preoperative computed tomography (CT) showing iso- or mixed-density subdural collection and SDH volume > 60 mL. There was selection bias for the procedure. Patients with subdural membranes were preferentially taken for TC as the percentage of subdural membrane found intraoperatively was significantly greater in trephine group (51.1%) than burr-hole group (17.6%) (p value < 0.001).When all the patients who showed membranes in CT scan were excluded, there was no statistical difference in the base line characteristics of both the groups. After excluding the patients with membranes in preoperative CT scan, there was no significant difference in recurrence rate between the two groups.In TC group with membranes, 8 out of 45 had recurrence, whereas in burr-hole group with membranes, 8 out of 12 had recurrence. This difference was statistically significant. (p value < 0.001). Conclusion Surgical intervention in both modalities improves patient outcome with an overall recurrence rate of 12.17%. In the absence of any identifiable membranes in preoperative CT scan, BHD is the preferred surgical intervention. We prefer TC as first choice for patients with membranes in CT scan.
