The surgical treatment of unilateral vocal cord paralysis (UVCP): qualitative review analysis and meta-analysis study.

PURPOSE: The objectives of this meta-analysis were to summarize the key surgical procedures for UVCP and to evaluate which of these is associated with better results in terms of vocal improvement. METHODS: A systematic review of the literature was conducted in search of articles focused on the comparison of voice outcome between different techniques for the UVCP treatment. Then, a quantitative analysis was carried out for papers published from 2013 onwards, reporting only adult patients with unilateral paralysis for each study, and each surgical technique was evaluated for its capability of achieving good functional outcomes in terms of GRBAS-I scale and maximum phonation time in seconds (MPT). RESULTS: The search identified 1853 publications. A total of 159 articles were stratified and included according to our selection criteria. 21 out of 159 articles were selected for quantitative synthesis. For trans-oral techniques: the mean GRBAS-I scale were 2.33 before injection and 0.41 after injection. The mean MPT before injection were 4.78 and 12.50 after injection. For open techniques the mean GRBAS-I scale were 2.43 before surgery and 0.68 after surgery. For open technique, the mean MPT were 3.50 before surgery and 12.40 after surgery. CONCLUSIONS: The two types of techniques lead to an improvement in terms of vocal outcomes emphasizing that from the examined literature an indication emerges to perform an early injection because this could reduce the possible need for a more invasive intervention of permanent medialization in the future.

Outcome in excised thymomas: role of prognostic factors and impact of additional malignancies on survival.

BACKGROUND AND AIMS: Although the management of thymomas has been extensively evaluated, the value of prognostic factors in the outcome of these patients remains unclear. METHODS AND RESULTS: The medical records of all patients who underwent resection of thymoma between January 1985 and September 2010 at a single thoracic unit were reviewed. Patients were followed up with reference to disease recurrence and development of additional malignancies (AM). Total thymectomy was performed in all 68 cases. Mean follow-up time was four years. Mean survival was 63.9 months. Mean disease-free interval was 13 months. Factors affecting prognosis were Masaoka staging and WHO histological sub-type. Patients with thymomas had a higher risk of developing AM when compared with a control population of individuals with other tumours (p = 0.0002). Among thymomas, the cortical subtype was associated with a higher risk of AM (p = 0.047) and mortality (p = 0.001). CONCLUSIONS: This data confirms that Masaoka staging and WHO histologic sub-type are the most important prognostic factors in patients with thymoma. Moreover, thymomas predominantly arising from the thymic cortex are associated with a higher risk of developing other malignancies and with poorer survival. The cortical origin of thymoma could therefore be considered as a significant prognostic factor.

Pleural granuloma mimicking malignancy 42 years after slurry talc injection for primary spontaneous pneumothorax.

BACKGROUND: Talc poudrage is considered a safe pleurodesis technique to improve the results of video-assisted thoracoscopic surgery in cases of primary spontaneous pneumothorax (PSP). METHODS: We report the case of a patient with left pleural pseudo-nodular plaque and a high metabolic rate upon PET scan suspected for malignancy, occurring 42 years after slurry talc injection for conservative treatment of PSP. The patient presented with coughing, chest pain and weight loss. Thoracotomy was required to obtain a diagnosis and perform a complete pleurectomy. RESULTS: Histology was conclusive for pleural talc granuloma. CONCLUSIONS: Indications and possible complications of talc use in young patients with PSP, and the management of possible consequent pleural lesions suspected for malignancy, need to be investigated.

Combined Percutaneous and Endovascular Treatment of Symptomatic Aneurysmal Bone Cyst of the Spine: Clinical Six Months. Follow-up of Six Cases.

We describe the usefulness of endovascular and direct percutaneous treatment as a therapy option for aneurysmal bone cysts (ABCs) of the spine. From January 2007 to December 2008, we treated six consecutive patients with symptomatic ABCs resistant to continuous medical management or with acute clinical onset of paraparesis at cervical, thoracic and lumbar spine level. Two patients were treated after emergency laminectomy. All patients were studied with an MRI protocol and multidetector CT with MPR reconstructions followed by angiographic control before treatment. The procedure was performed under general anaesthesia for all patients. Under CT or fluoroscopy guidance, percutaneous treatment was performed either by direct injection of Glubran(®) diluted at 30% with Lipiodol(®) only, or combined with endovascular treatment by Onyx® injection. Clinical and X-ray follow-up was performed at three and six months. Combined endovascular and percutaneous treatment for ABCs was successful and led to an excellent outcome in five out of six patients with clinical improvement. There were no periprocedural or subsequent clinical complications and the glue resulted in successful selective permanent occlusion with intralesional penetration. Direct sclerotherapy resulted in immediate thrombosis of the malformation with no progression of symptoms. Complete healing was observed in five out of six aggressive lesions. No major complications were noted. At six month follow-up the symptoms had completely resolved and X-ray control showed a partial or total sclerotic reaction of the lesion with stable clinical results (no partial or clinical abnormalities). One patient had a recurrence of the ABC with spinal cord cervical clinical symptomatology. Combined endovascular and percutaneous treatment or direct percutaneous sclerotherapy with glue alone are important, safe, effective therapy options for symptomatic aneurysmal bone cyst. Results are stable and confirmed by clinical and X-ray follow-up six months after treatment.

Combined treatment with stenting and coiling for complex cerebral aneurysms: preliminary experience of twenty aneurysms treated by new generation intracranial stents.

We describe our preliminary experience of a combined treatment with stenting and coiling for ruptured and unruptured complex cerebral aneurysms (AA) using new generation stents (Enterprise(®), LeoPlus(®), Solitaire(®)). Eighteen patients, 20 AA, were treated by stenting and coiling. Some had sacciform wide-necked partially thrombosed aneurysms, other had fusiform AA. Six ruptured AA were treated early, while the other 14 were treated electively. In four out of 20 AA coiling was performed by Jailing technique and in three cases a remodelling technique was also performed. Patients with ruptured AA were previously administered a heparin protocol during the procedure and given aspirin (500 mg) after stenting. Patients with unruptured AA were administered plavix and aspirin for seven days before the procedure. Post-intervention medical therapy was plavix and aspirin for six months, then aspirin (100 mg). MRA and DSA at were performed after six to 12 months. Treatment was successfully performed in all cases. The stent could be navigated within the cerebral arteries without any exchange procedure, and thanks to its retractability, it was positioned accurately. No procedure-related complication occurred. Complete occlusion of the aneurysm was observed in 14/20 AA, partial occlusion with residual sac in 2/20. At four months a residual neck was observed in 4/20 with an increase in residual sac at one year in one case treated by coiling. At one year, MRA showed a reduction of the neck in one case and a stable residual neck in the other. Stenting and coiling for sacciform wide-necked or fusiform aneurysms is a safe procedure without complications. Medical-therapy pre and post procedure associated with follow-up are necessary to establish the occlusion rate.

Endovascular treatment of a fusiform cerebral aneurysm by stenting alone. Two case reports and literature review.

This paper illustrates two cases of stent-in-stenting treatment of unruptured, symptomatic, fusiform intracerebral aneurysms. Two unruptured symptomatic fusiform intracerebral aneurysms were treated by the stent-in-stent only technique. The first patient, a 35-year-old woman, had a partially thrombosed fusiform aneurysm in the left carotid siphon with the chief complaint of headache and left ophthalmoplegia. The second patient, a 60-year-old man, had a symptomatic fusiform aneurysm of the left V4 with recurrent transient ischemic attacks. No cervical trauma or infection was present in either patient. A CT, CTA and DSA were performed on hospital admission. Both patients were previously premedicated with Clopidrogel + ASA for five days before treatment. By DSA, both patients were treated under general anesthesia with a heparin protocol plus ASA (500mg) at stent placement. A double stent-in stent was placed in both patients. Post-intervention medical therapy was clopridogel and ASA for three months, then aspirin (100mg) daily for six months. CTA and DSA were performed at six and 12 months. Both stents were positioned without any difficulty and could be navigated within cerebral arteries without any exchange procedure, and thanks to their retractability, they were accurately positioned. No bleeding at post-treatment CT was noted. At 12 months follow-up, a complete disappearance of the aneurysm and preservation of the parent vessel was observed for both patients. No procedure-related complication occurred. No intra-stent stenosis or intimal hyperplasia was observed. Stenting for fusiform aneurysms is a safe procedure without complications. Medical therapy pre-post procedure associated with follow-up is necessary to prevent/establish the incidence of occlusion.

VATS for congenital lobar emphysema: a case report.

UNLABELLED: Congenital lobar emphysema (CLE) is a rare congenital lung disease consisting in overinflation of a pulmonary lobe. Adult onset of CLE is therefore unusual, often presented with mild symptoms. The authors report a very uncommon case of congenital segmental emphysema diagnosed in a 21-year-old non-smoking man because of recurrent right pneumothorax. Indication to pulmonary resection was established according to functional limitation, radiological findings of right upper lobe segmental emphysema with corresponding bronchial agenesia, scintigraphic result of extremely reduced ventilation and perfusion of lung emphysematous area and recurrency of pneumothorax. The intervention was carried out by 3-portal video-assisted thoracic surgery (VATS) using single-lung ventilation leading to determine precisely how much lung to resect thanks to the obvious and clear-cut distinction between functioning and non functioning parenchyma of the upper lobe. A stapler wedge resection by VATS was thus obtained, that, as far as the author's knowledge, it is the first case of endoscopic parenchymal sparing resection in CLE. Even though congenital lobar emphysema is rare, clinical awareness of this condition is important for early diagnosis and effective surgical treatment that in this case led to favourable RESULTS: The VATS procedure seems to be an advantageous approach.
