Retrospective Analysis of Implant Success Rates and Bone Volumetric Changes After Lateral Window Sinus Augmentation with β-Tricalcium Phosphate

Insufficient bone volume is a common problem encountered in the rehabilitation of the edentulous posteriormaxilla with implant?supported prostheses. Although adequate bone height can be achieved using variousmaxillary sinus augmentation techniques, these procedures have been practiced successfully. However,significant complications occur such as perforations or tearing. To maintain the integrity of Schneiderianmembrane subsequently increasing the success rate a retrospective analysis is carried out on varioustechniques with complications which occur during and after treatment. This review will help the readers tounderstand the intricacies of sinus augmentation by using direct techniques.

Endoscopic Dcr

Objective To compare the outcomes of various techniques of endoscopic dacryocystorhinostomy (DCR). Study Design Retrospective case record analysis. Settings Tertiary care referral center. Subject and Methods Retrospective analysis of case records was carried out pertaining to the period from January 1996 to September 2017 with respect to patients who had undergone endoscopic DCR with either the standard technique or one of its modifications. Case notes showing well-documented preoperative evaluation, operative details, postoperative assessment, and minimum 6-month follow-up were considered. The outcomes were measured on the basis of patients’ postoperative symptoms, clinical examination, and sac-syringing results. Results A total of 423 patients were included in the study. Of these, 169 underwent standard endoscopic DCR; 87, endoscopic DCR with stent; 19, endoscopic DCR with mitomycin C; 62, powered DCR; 29, laser-assisted DCR; and 57, balloon DCR. There was no statistically significant difference in success rates, recurrences, or complications of various techniques at 3 or 6 months. Mean operating time was lowest for balloon DCR (mean ± SD, 27.1 ± 3.1 minutes), followed by standard endoscopic DCR (38.2 ± 3.6 minutes; P = .001). Conclusion Standard endoscopic DCR and its more sophisticated modifications were equally effective and safe in managing distal nasolacrimal drainage obstruction. Balloon DCR, followed by standard endoscopic DCR, was significantly faster than other techniques.

Abstract Objective: To evaluate the success and complication rates of ultrasound-guided renal biopsy at a tertiary care hospital. Materials and Methods: This was a retrospective analysis of 97 ultrasound-guided renal biopsies, all performed by the same radiologist, between 1 March, 2017 and 31 October, 2019. Results: Of the 97 biopsies evaluated, 87 had a definitive pathological diagnosis. In five cases (5.4%), the biopsy results were inconclusive and a second procedure was required. In seven procedures (7.6%), there were complications, all of which were properly resolved. Conclusion: Ultrasound-guided renal biopsy has proven to be a safe, effective method for the diagnosis of nephropathies, with high success rates.

Procedural Success

Abstract Background: There is a consensus, that transradial-access (TRA) for coronary procedures should be preferred over transfemoral-access (TFA). Previously, forearm-artery-angiography was mainly performed when difficulties during the advancement of the guidewire were encountered. We explored the implication of a standardized forearm-angiography (SFA) on procedural success rates of TRA.Methods: 1191 consecutive cases were assessed retrospectively. Primary TFA rates, crossover to TFA, reasons for forearm-artery-access (FAA) failure, the prevalence of kinking at the level of the forearm and the occurrence of vascular complications were analyzed.Results: Primary FAA access was attempted in 97.9%. Crossover to TFA after a primary or secondary FAA attempt was necessary in 2.8%. Severe kinking was the most frequent cause of FAA failure and occurred in 3.0%. A second or third FAA attempt to avoid TFA was successful in 81%. Severe kinking at the level of the forearm was reported in 1.8%.Conclusion:This is the first study to provide detailed success rates of a primary FAA strategy combined with SFA. While severe kinking proved to be a rare but relevant challenge for FAA success, the prevalence of arterial spasm was marginal. Multiple attempts of FAA to avoid TFA might be safe possibly due to collateral blood supply.
