Although often presenting without symptoms, these aneurysms bear the potential for life-threatening complications, primarily from the looming risk of rupture. We present the case of a 42-year-old Malay gentleman with a history of bilateral pedal edema and dyspnea on exertion who was diagnosed with a ruptured sinus of Valsalva aneurysm. The patient underwent successful surgical repair of the aneurysm, leading to symptomatic improvement and favorable outcomes. This case highlights the importance of early diagnosis and prompt surgical intervention in managing this uncommon condition.展开更多

Multifactorial aetiology contributes to its refractoriness. Functional endoscopic sinus surgery (FESS) is the most common surgical technique preferred in CRS not responding to medical management, showing high success rates. However, some failure has been noted, requiring revision FESS. CT (Computed Tomography) is a diagnostic tool for CRS, and aids in improving surgical outcomes. Combined with the Lund-Mackay scoring system, CT can help stage the CRS, predicting the need for revision surgery. <strong>Methods:</strong> In our paper, we aimed to study the relationship between severity of CRS using radiological staging and revision of functional endoscopic sinus surgery, assessing outcome after at least 1 year of follow-up. There was a single centre retrospective study involving 150 patients selected by random sampling, to study the correlation between the severity of chronic rhinosinusitis and revision of functional endoscopic sinus surgery (FESS). The study was conducted in the ENT department of King Hamad University Hospital, Bahrain for a time period of 6 months. Records were scanned and scored using Lund-Mackay system. Lund Mackay score of 10 and above was considered severe. The relation between increased severity with Lund Mackay score on the CT scan and the need for revision sinus surgeries was then determined. <strong>Results and Conclusion:</strong> This study concludes that LMS score in CT scans can be used to predict the outcomes of primary FESS procedure and the need for revision surgery in the management of CRS.展开更多

Their clinical presentation may range from being asymptomatic as an incidental finding on cardiac imaging to symptomatic presentations related to the compression of adjoining structures or intracardiac shunting caused by rupture of the SOVA mostly into the right side of the heart. The compression leads to findings of tricuspid valve regurgitation, right ventricular outflow tract (RVOT) obstruction and rarely complete heart block (CHB). Dissection or erosion into interventricular septum is one of the rarest complications of SOVA. The symptomatic presentation is almost always a surgical emergency. Here we present a case report of a patient with unruptured sinus of valsalva originating from right sinus dissecting into interventricular septum causing complete heart bock. In this case after surgical correction the complete heart block reverted to sinus rhythm.展开更多

Their mechanism is most commonly triggered activity from delayed after-depolarizations and successful ablation is performed at the site of earliest endocardial activation. Re-entrant mechanisms have been rarely described. We report a case of an otherwise healthy patient who ultimately underwent six electro-physiology studies (EPS) and suffered numerous implantable cardiac defibrillator (ICD) discharges prior to the successful radiofrequency ablation (RFA) of two idiopathic VOT tachycardias. During the sixth EPS, a proximal aortogram demonstrated a left aortic sinus of valsalva (LASV) aneurysm. Subsequntly, a novel and successful RFA strategy of aneurysm isolation was undertaken. The presence of multiple clinical or inducible VT morphologies and the characterization of a VT as re-entrant should raise concerns that a complex arrhythmogenic substrate is present and defining the anatomy with angiography or an alternative imaging modality is essential in achieving a successful ablation strategy.展开更多

Endoscopic Sinus Surgery (ESS) is one of the surgeries which need a clear field and the amount of bleeding profoundly impacts the ability of surgeons. Current study was designed to evaluate the effect of remifentanil combined with propofol versus Isoflurane on blood loss during ESS and its possible interaction with Depth of Anesthesia. Fifty one patients comprising 15 females and 36 males undergoing ESS were chosen for this study. One group received propofol and remifentanil to induce and maintain anesthesia and the second group received Isoflurane. Mean Arterial Blood Pressure (MAP), Depth of Anesthesia and total blood loss were recorded for the patients of both group. Data were analyzed using t-test, Repeated Measures ANOVA and Pearson’s correlation. P 0.05 was considered statistically significant. Both agents induced hypotension during surgery. No significant difference was observed in total blood loss between two groups. DA was decreased in both groups, but no significant correlation was found between DA and MAP or DA and blood loss. There is no significant difference between remifentanil combined with propofol and Isoflurane in decreasing blood loss during ESS, thus we suggest usage of hypotensive anesthetic agent regardless of its type is ESS.展开更多

We have developed a detailed concept on training these surgical skills on the lamb's head. This simple and extremely cheap model offers the possibility of training even more demanding and advanced procedures in human endonasal endoscopic surgery such as: frontal sinus surgery, orbital decompression, cerebrospinal fluid-leak repair followed also by the naso-septal flap, etc. Unfortunately, the sphenoid sinus surgery cannot be practiced since quadrupeds do not have this sinus. Still, despite this anatomical limitation, it seems that the lamb's head can be very useful even for the surgeons already practicing EESS, but in a limited edition because of a lack of the experience and dexterity. Only after gaining the essential surgical skills of this demanding field it makes sense to go for the expensive trainings on the human cadaveric model.展开更多

CT scan evaluation of aero-digestive tract in the immediate post-operative period was done to ascertain the cause pertaining to any surgical trauma or anaesthesia related complications. Such a case previously unreported has been included in this study. A simple close monitoring after establishing the cause is usually sufficient in management of such related or unrelated complications during FESS which in our case was likely to be anaesthesia related. Published data of such a complication assists in building up a good and effective medical audit based on ethical practice. This paper stresses the importance of immediate CT scan of aero-digestive tract in evaluating the cause.展开更多

For the recent 10 years, we summarized the experience of the rhinology unit of our department regarding orbital injury and complications of ESS for sinonasal inflammatory disorders. One thousand seventy-three patients (1869 sides) from January 1, 2003 to December 31, 2012 undergoing ESS for sinonasal inflammatory diseases were enrolled in the present study. The age of the patients ranged from 8 to 81 years, mean age 49 years. Orbital injury and complications were observed in 13 patients (13 sides), which corresponded to 0.7% of the operated sides and 1.2% of the patients. Eight patients showed herniation of orbital fat alone through the injury of the lamina papyracea. The protruding orbital fat was snipped and cut using forceps in 2 patients. Removal of exposed orbital fat using powered instruments was performed in 3 patients, two of whom transiently showed periorbital edema postoperatively. No permanent complications were observed. Meticulous preoperative and perioperative planning is critical to prevent orbital complications. Especially, exposure of the periorbit and herniation of orbital fat after lamina injury with powered instrumentation dramatically increases the potential for more severe complications.展开更多

Methods: A retrospective analysis of 41 patients undergoing FESS for CRS was performed. All patients underwent pre-operative computed tomography (CT). Patients with fungal sinusitis, allergic fungal sinusitis, and eosinophilic sinusitis were excluded. After FESS, normalized sinus mucosa was confirmed by CT and endoscopy in all patients. Postoperative antibiotic therapy consisted of first-line and second-line regimens. Garenoxacin (GRNX), or clarithromycin (CAM, 400 mg/day) was used as the first-line regimens and low-dose macrolide therapy (CAM, 200 mg/day) was used as the second-line regimen and was prescribed at outpatient visits based on our clinical criteria. Results: Second-line antibiotic therapy (low-dose CAM) was not necessary in 12 of 41 (29%) patients, while it was prescribed in 29 of 41 (71%). The mean duration of low-dose CAM therapy after FESS was 36 days (range 7 to 122 days;median, 25 days). Patients who received second-line therapy (n = 29) were divided into two groups based on the choice of first-line therapy, a GRNX group (n = 13) and a non-GRNX group (n = 16). Those in the non-GRNX had longer periods of postoperative CAM therapy than those in the GRNX group. Conclusion: GRNX was associated with a shorter duration of low-dose macrolide therapy after FESS, and 29% of patients did not need any low-dose macrolide therapy postoperatively. Therefore, macrolide antibiotics should not be routinely prescribed after FESS.展开更多

Method: A total of 90 cases of patients with CRS were randomly divided into control group (n=45) and observation group (n=45) according to the lottery method. Both groups were treated with endoscopic sinus surgery. On the basis of this, control group was given Budesonide suspension and observation group was treated with Desloratadine Citrate Disodium combined with Budesonide suspension. The change of serum IgE, EOS and inflammatory factors were measured before and after operation in all subjects. Results: There was no significant difference in IgE and EOS levels between control group and observation group before treatment. After treatment, the levels of serum IgE and EOS in the two groups were significantly lower than those before treatment. Moreover, after treatment, observation group was lower than control group, and the difference was significant. There was no significant difference in inflammatory factors level between control group and observation group before treatment. After treatment, the levels of serum IL-6, IL-8, TNF-α and hs-CRP were significantly lower than those before treatment. After treatment, observation group was lower than the control group in the same period, the difference was significant. Conclusion:Combined Desloratadine Citrate Disodium treatment for CRS patients on the basis of endoscopic sinus surgery and Budesonide Nasal Spray treatment, it can more effectively reduce serum IgE and EOS levels, decrease the inflammatory response. Therefore it was a potential effective treatment for patients with CRS.展开更多

Those in the non-GRNX had longer periods of postoperative CAM therapy than those in the GRNX group. Conclusion: GRNX was associated with a shorter duration of low-dose macrolide therapy after FESS, and 29% of patients did not need any low-dose macrolide therapy postoperatively. Therefore, macrolide antibiotics should not be routinely prescribed after FESS.
文摘Objective: To observe the clinical application of Desloratadine Citrate Disodium combined with Budesonide suspension in patients with chronic rhinosinusitis CRS after endoscopic sinus surgery, and analyze the change of serum immunoglobulin E (IgE), eosinophils (EOS) and inflammatory factors level in patients. Method: A total of 90 cases of patients with CRS were randomly divided into control group (n=45) and observation group (n=45) according to the lottery method. Both groups were treated with endoscopic sinus surgery. On the basis of this, control group was given Budesonide suspension and observation group was treated with Desloratadine Citrate Disodium combined with Budesonide suspension. The change of serum IgE, EOS and inflammatory factors were measured before and after operation in all subjects. Results: There was no significant difference in IgE and EOS levels between control group and observation group before treatment. After treatment, the levels of serum IgE and EOS in the two groups were significantly lower than those before treatment. Moreover, after treatment, observation group was lower than control group, and the difference was significant. There was no significant difference in inflammatory factors level between control group and observation group before treatment. After treatment, the levels of serum IL-6, IL-8, TNF-α and hs-CRP were significantly lower than those before treatment. After treatment, observation group was lower than the control group in the same period, the difference was significant. Conclusion:Combined Desloratadine Citrate Disodium treatment for CRS patients on the basis of endoscopic sinus surgery and Budesonide Nasal Spray treatment, it can more effectively reduce serum IgE and EOS levels, decrease the inflammatory response. Therefore it was a potential effective treatment for patients with CRS.
