A fatal iatrogenic right vertebral injury after transoral odontoidectomy and posterior cervical stabilization for a type II odontoid fracture.
2014
Abstract The authors present a singular case of an iatrogenic right vertebral artery injury, involving a 67 year-old man, who reported a type II odontoid fracture (Anderson and D'Alonzo Classification) and posterior atlantoaxial dislocation following a road traffic accident. A small injury involving the right vertebral artery occurred as a consequence of transoral odontoidectomy and posterior cervical stabilization. It was caused by bone spicules of spinal origin and their presence was confirmed by the histological section of the right vertebral artery at the level of C1–C2. The case confirms how iatrogenic vertebral artery injuries during cervical spine surgery may be potentially lethal, e…
Severe odontogenic infection: An emergency. Case report
2017
Odontogenic infections (OI) are a major reason for consultation in dental practice. They affect people of all ages, and most of them respond well to current medical and surgical treatments. However, some OI can spread to vital and deep structures, overcome the host immune system - especially in diabetic, immunocompromised or weakened patients - and even prove fatal. Ludwig's angina is a severe form of diffuse cellulitis that can have an acute onset and spread very rapidly, bilaterally affecting areas of the head and neck, and may prove life threatening. A case of severe dental infection is presented in which emphasis is placed on the importance of airway maintenance, followed by surgical de…
Spontaneous Meckel's cave hematoma: A rare cause of trigeminal neuralgia
2015
Background: The most common etiology of classic trigeminal neuralgia (TN) is vascular compression. However, other causes must be considered. Among these, spontaneous hematoma of the Meckel′s cave (MC) causing symptomatic TN is very rare. Case Description: We present the case of a 60-year-old woman with a 2-month history of left TN and diplopia. Neuroradiological examinations revealed a well-defined hematoma in the left MC. The patient underwent surgical decompression with a progressive neurological improvement. Conclusion: Despite the number of lesions potentially affecting the MC, spontaneous hemorrhage is rare but should be taken into account in the differential diagnosis.
An Atypical Case of Taravana Syndrome in Mediterraneo
2010
Dysbaric accidents are usually referred to compressed air-supplied diving. Nonetheless, diving accidents are known to have occurred among breath-hold divers also and some cases are reported in medical literature. A male professional breath hold diver (57 year old) presented neurological disorders as dizziness, sensory numbness, blurred vision and left phronto-parietal pain after many dives to a 30-35 meters seawater depth. He went home after the regression of the symptoms and runned 8 Km the following morning. Pain, sensory numbness and dizziness occurred after running. He went by himself to the hospital where he had a grand mal seizure and lost consciousness. A magnetic resonance imaging o…
Abdominal Compartment Syndrome: diagnostic evaluation and possible treatment
2020
BACKGROUND: Abdominal compartment syndrome (ACS) is a clinical condition caused by an increase in intra-abdominal pressure. The incidence is variable, based on the type of patients taken into consideration, increasing exponentially in critical conditions, such as traumatized, burned patients in shock. The syndrome can also follow surgical procedures like transplantation of abdominal organs, for example configuring rare pictures such as RACS (post-transplant kidney syndrome). In most cases the symptoms are non-specific and varied according to the different etiology of the ACS, therefore the diagnosis may not be immediate. AIM: The aim of this work is to evaluate the best therapeutic approach…
Carbon dioxide levels during pre-hospital active compression–decompression versus standard cardiopulmonary resuscitation
1998
Abstract In a prospective randomised study we investigated end-tidal carbon dioxide levels during standard versus active compression–decompression (ACD) cardiopulmonary resuscitation (CPR) assuming that the end-tital carbon dioxide reflects cardiac output during resuscitation. In each group 60 patients with out-of-hospital cardiac arrest were treated either with the standard or the ACD method. End-tidal CO 2 ( p et CO 2 , mmHg) was assessed with a side-stream capnometer following intubation and then every 2 min up to 10 min or restoration of spontaneous circulation (ROSC). There was no difference in p et CO 2 between both patient groups. However, CO 2 was significantly higher in patients wh…
Tissue Sparing Posterior Cervical Indirect Decompression and Fusion in Foraminal Stenosis
2016
Treatment for patients with cervical foraminal stenosis that present with cervical radiculopathy has experienced rapid progress. Cervical spine surgical options have improved through advances in imaging, instrumentation, implant innovations and novel surgical techniques. While historical treatments are largely safe, comorbidities associated with procedures such as ACDF, TDR, and posterior foraminotomy beg the question if these procedures are too much surgery for select patients that could benefit from a tissue sparing approach. This chapter will introduce a novel, less disruptive surgical technique for achieving indirect decompression and fusion utilizing an intervertebral cervical implant.…
Equilibrium and disequilibrium degassing of a phonolitic melt (Vesuvius AD 79 “white pumice”) simulated by decompression experiments
2007
Abstract Equilibrium and disequilibrium degassing of a volatile phase from a magma of K-phonolitic composition was investigated to assess its behavior upon ascent. Decompression experiments were conducted in Ar-pressurized externally heated pressure vessels at superliquidus temperature (1050 °C), in the pressure range 10–200 MPa using pure water as fluid phase. All experiments were equilibrated at 200 MPa and then decompressed to lower pressures with rates varying from 0.0028 to 4.8 MPa/s. Isobaric saturation experiments were performed at the same temperature and at 900–950 °C to determine the equilibrium water solubility in the pressure range 30–250 MPa. The glasses obtained from decompres…
The Role of Endoscopy in the Treatment of Acute Traumatic Anterior Epidural Hematoma of the Cervical Spine: Case Report
1997
OBJECTIVE AND IMPORTANCE: Epidural hematoma (EDH) of the spine represents an uncommon neurosurgical disorder that sometimes requ;res emergent surgical decompressive therapy. Traumatic EDH of the cervical spine is exceedingly rare. The hematoma is usually located dorsally in the epidural space. We present one case of acute EDH located ventrally in the cervical spine. Special emphasis is placed on the role of spinal endoscopy in surgical treatment. CLINICAL PRESENTATION: After a fall from a tree, a 69-year-old man with rapidly increasing tetraparesis was referred to our institution. Plain films of the cervical spine revealed nothing abnormal. The results of computed tomography were highly sus…
Trigemināla neiralģija: ārstēšanas analīze pēc mikrovaskulāras dekompresijas ķirurģijas
2017
Ievads: Trigemināla neiralģija (TN) ir sindroms, kas izsauc ļoti stipras lēkmjveida sāpes, kas izstaro sejā un ko var raksturot kā durošus, līdzīgus elektriskai strāvai paraksizmus. Ir uzskatīts, ka TN etioloģijas pamatā ir hroniskais neirovaskulārais kontakts (t.s. neirovaskulārais konflikts) starp asinsvadu un nervu. Rezultātā asinsvads spiež uz nervu, veidojas nervu mielīna apvalka bojājums, pastāvīgs nervu šķiedru nociceptīvo receptoru kairinājums, kas izpaužas ar sāpēm. Visbiežāk patoloģiju diagnosticē diezgan vēli. Terapija sākumposmā ir Carbamazepine (CBZ), Un ja tas nav efektīvs, tad jādomā par operatīvo ārstēšanu. Ņemot vērā, ka vaskulārā kompresija ir visbiežākais iemesls primārai…
