Puncture Wound Hemostasis and Preparation of Samples for Montaged Wide-Area Electron Microscopy Analysis.

Hemostasis, the process of normal physiological control of vascular damage, is fundamental to human life. We all suffer minor cuts and puncture wounds from time to time. In hemostasis, self-limiting platelet aggregation leads to the formation of a structured thrombus in which bleeding cessation comes from capping the hole from the outside. Detailed characterization of this structure could lead to distinctions between hemostasis and thrombosis, a case of excessive platelet aggregation leading to occlusive clotting. An imaging-based approach to puncture wound thrombus structure is presented here that draws upon the ability of thin-section electron microscopy to visualize the interior of hemostatic thrombi. The most basic step in any imaging-based experimental protocol is good sample preparation. The protocol provides detailed procedures for preparing puncture wounds and platelet-rich thrombi in mice for subsequent electron microscopy. A detailed procedure is given for in situ fixation of the forming puncture wound thrombus and its subsequent processing for staining and embedding for electron microscopy. Electron microscopy is presented as the end imaging technique because of its ability, when combined with sequential sectioning, to visualize the details of the thrombus interior at high resolution. As an imaging method, electron microscopy gives unbiased sampling and an experimental output that scales from nanometer to millimeters in 2 or 3 dimensions. Appropriate freeware electron microscopy software is cited that will support wide-area electron microscopy in which hundreds of frames can be blended to give nanometer-scale imaging of entire puncture wound thrombi cross-sections. Hence, any subregion of the image file can be placed easily into the context of the full cross-section.

P. aeruginosa infection of the ulna, a rare complication after arterial puncture.

Pseudomonas aeruginosa, a Gram-negative bacterium known to induce severe infections, is seldomly reported in scientific literature as a contributor of osteomyelitis. In this case report, a 71-year-old woman exhibited recurring infections and enduring forearm pain. A subsequent MRI revealed osteomyelitis in the distal ulna, linked to an arterial blood gas sample taken months earlier. Despite undergoing multiple extended courses of antibiotic treatment, the patient eventually underwent surgery on her left forearm. Biopsy cultures conclusively confirmed the presence of P. aeruginosa.

Development and evaluation of an algorithm for peripheral venous catheter placement (ALCOV): protocol for a quasi-experimental study.

INTRODUCTION: Multiple punctures during peripheral venous catheter (PVC) placement increase the risk of complications. Scoring for adult difficult intravenous access (A-DIVA Scale) exists but has never been assessed in the framework of a care algorithm (scoring associated with a new decision-making tree for puncture conditions, the A-DIVA Tree). We seek to implement an catheter placement algorithm to decrease the mean number of punctures per patient. The algorithm will be adjusted based on obstacles and levers revealed by the analysis of clinical data. The benefits of the algorithm will be assessed using a step-by-step implementation of the approach. METHODS AND ANALYSIS: 794 PVC placements will be recorded in two inclusion centres (50%/50%). In phase I, 297 PVC placements will be collected, and 16 individual semistructured interviews will be conducted to evaluate the centres' practices. In phase II, 200 PVC placements will be recorded to assess the impact of the A-DIVA Scale alone. The interphase will allow preliminary results based development of the A-DIVA Tree. In phase III, 297 PVC placements will be recorded to assess the impact of the algorithm on the mean number of punctures per patient. ETHICS AND DISSEMINATION: The study and related consent forms were approved by an institutional review board (Comité de Protection des Personnes Sud-Méditerranée I) on 25 April 2023 under reference number 2023-A00223-42. The results will be disseminated in the form of original articles, presentations and guidelines. TRIAL REGISTRATION NUMBER: NCT05935228.

Treatment of acute basilar artery occlusion by retrograde puncture via the vertebral artery approach: A care-compliant case report.

BACKGROUND: Vertebral artery stump syndrome (VASS) is a cause of acute stroke. Owing to the particularity of the pathogenesis of VASS, interventional treatment of VASS is difficult. Common mechanical thrombectomy approaches include femoral and radial artery approaches. However, conventional approaches may not be suitable for VASS. If effective measures are not taken to open offending vessels in time, this can lead to a high rate of disability. In recent years, no consensus has been reached regarding surgical methods for treating VASS. PATIENT CONCERNS: The patient presented to the emergency department with a 2-hour history of disturbance of consciousness. DIAGNOSIS: After neurological and magnetic resonance imaging examinations, the patient was diagnosed with acute large vessel occlusive posterior circulation cerebral infarction. METHODS: The patient's symptoms were not relieved after intravenous infusion of argatroban (10 mg) at a local hospital. We first attempted to open the occluded vertebral artery through normal approaches but failed. We then punctured the vertebral artery, successfully opened the occluded vertebral artery, and performed mechanical thrombectomy. RESULTS: The patient underwent successful vertebral artery puncture and mechanical thrombectomy, with no evidence of postoperative bleeding or vascular injury at the puncture site. The patient regained consciousness the day after surgery but remained impaired in physical activity. After 4 months of rehabilitation, the patient recovered completely. CONCLUSION: When the conventional approach cannot meet the requirements of mechanical thrombectomy, reverse puncture of the vertebral artery is a feasible surgical method for patients with VASS. However, due to the small number of cases, a series of safety problems such as potential puncture failure, hemorrhage after puncture, and vascular occlusion still need to be further explored.

Neuroendoscopy-Assisted Entire-Process Visualization Technique of Ventricular Puncture for External Ventricular Drainage.

OBJECTIVE: This study aimed to investigate the feasibility, safety, and efficacy of the neuroendoscopy-assisted entire-process visualization technique (NEAEVT) of ventricular puncture for external ventricular drainage. METHODS: Eighty-eight patients with cerebral hemorrhage who underwent unilateral ventricular puncture for external ventricular drainage in our hospital from June 2021 to June 2023 were analyzed. Patients were grouped according to puncture technique: NEAEVT (30 patients), freehand (30 patients), and laser-navigation-assisted (28 patients). Operation time, drainage tube placement, and catheter-related hemorrhage incidence were compared between the groups. RESULTS: Mean operation time significantly differed between the freehand, NEAEVT, and laser-assisted groups (17.07, 18.37, and 34.04 min, respectively; P <0.0001). The position of the drainage tube was optimal or adequate in all patients of the NEAEVT group; optimal/adequate positioning was achieved in 80% of the freehand group. No catheter-related hemorrhage occurred in the NEAEVT group. Three freehand group patients and 2 laser-assisted group patients experienced catheter-related hemorrhage. CONCLUSION: The NEAEVT of ventricular puncture is accurate and achieves ventricular drainage without significantly increasing surgical trauma, operation time, or incidence of hemorrhage.

The Short-Term Results of the Modified Concentric-Needle Technique for Single-Puncture Arthrocentesis: A Preliminary Study.

OBJECTIVE: To determine the clinical applicability of the modified concentric cannula technique (CCT), focusing on the duration of the arthrocentesis, the number of reposition of cannula, and the occurrence of complications. STUDY DESIGN: Descriptive study. Place and Duration of the Study: Department of Oral and Maxillofacial Surgery, Ankara Yildirim Beyazit University, Ankara, Turkiye, between September 2021 and May 2022. METHODOLOGY: Forty patients with Wilkes III temporomandibular joints (TMJ) internal derangement were identified and 13 patients who met the inclusion criteria were reviewed. The main outcomes regarding the clinical applicability of modified CCT included the duration of arthrocentesis, the number of reposition of cannula, and the occurrence of complications. RESULTS: The values of maximum mouth opening (MMO) without pain and MMO without assistance measured in the immediate postoperative period and at the 4th and 8th postoperative weeks were found to be significantly higher than the pre-arthrocentesis values. The values of MMO with assistance measured in the immediate postoperative period and at the 8th postoperative week were also significantly higher than the baseline values. Compared with preoperative values, notable decreases in pain scores were observed at the 4th (p = 0.003) and 8th (p = 0.002) postoperative weeks. The assessment of the jaw dysfunction also revealed significantly lower scores at the 4th (p = 0.024) and 8th (p <0.001) postoperative weeks. CONCLUSION: Modified CCT of arthrocentesis substantially decreased pain and improved mandibular functions in patients with internal derangement of TMJ. Additionally, this technique could be performed with a reduced number of cannula relocations and required a shorter operative time even with the use of a higher irrigation volume during the lavage procedure. KEY WORDS: Arthrocentesis, Temporomandibular joint disorder, Temporomandibular joint.

[Expert consensus on ultrasound guided thyroid and neck lymph node puncture (2023 edition)].

Thyroid nodule and cervical lymph node biopsy is the main clinical method for evaluating the condition and determining the follow-up treatment plan. The literature on thyroid nodule puncture predominantly focuses on thyroid fine needle puncture, and there are limited systematic articles on coarse needle aspiration for thyroid-related diseases and needle biopsy of thyroid-related cervical lymph node diseases. However, this shortage of articles does not reflect the diagnostic value of coarse needle aspiration in thyroid biopsy and cervical lymph node-related diseases. Currently, different departments of many hospitals in China are conducting or planning to perform needle biopsy of thyroid and cervical lymph node-related diseases to improve the standardization and safety of related operations. Standardization is needed for the indications, contraindications, perioperative period, postoperative complications management, puncture specimen processing, and related genetic analysis of thyroid and cervical lymph node puncture. For this purpose, Interventional Ultrasound Committee of Chinese College of Interventionalists organized a panel of domestic experts in the field of thyroid diseases to discuss and formulate a consensus. Based on the latest research progress, combined with the clinical realities in China, this Expert Consensus on Ultrasound Guided Thyroid and Neck Lymph Node Puncture (2023 edition) is released.

Inadvertent Puncture of Dilated Right Ventricle During Transversus Thoracic Muscle Plane Block: Lessons Learnt.

ABSTRACT: The transversus thoracic muscle plane (TTP) block is gaining widespread recognition in cardiac surgery, particularly in facilitating fast-tracking. Here, we report a case of inadvertent puncture of the right ventricle (RV) during the administration of ultra sound-guided (USG) TTP block in a 3-year-old child posted for atrial septal defect (ASD) closure and mitral valve repair. We also discuss the care that should be taken to avoid such complications and such cases require extra caution during TTP block.

Ultrasound-guided renal puncture followed by endoscopically guided tract dilatation vs standard fluoroscopy-guided percutaneous nephrolithotomy for non-opaque renal stones; a randomized clinical trial.

This study was designed to evaluate the non-inferiority of ultrasound puncture followed by endoscopically guided tract dilatation compared to the standard fluoroscopy-guided PCNL. Forty patients with non-opaque kidney stones eligible for PCNL were randomly divided into two groups. The standard fluoroscopy-guided PCNL using the Amplatz dilator was performed in the XRAY group. In the SONO group, the Kidney was punctured under an ultrasound guide followed by tract dilatation using a combination of the Amplatz dilator based on the tract length and an endoscopically guided tract dilatation using a bi-prong forceps in cases of short-advancement. The primary outcome was successful access. In 90% of cases in the XRAY and 95% in the SONO group access dilatation process was performed uneventfully at the first attempt (p = 0.5). In 45% of cases in the SONO group, bi-prong forceps were used as salvage for short-advancement. In one case in the X-ray group over-advancement occurred. One month after surgery, the stone-free rate on the CT-scan was 75% for the X-ray group and 85% for the SONO group (p = 0.4). There were no significant differences in operation time, hospitalization duration, transfusion, or complication rates between the two groups. We conclude that ultrasound-guided renal puncture, followed by endoscopically guided tract dilatation can achieve a high success rate similar to X-ray-guided PCNL while avoiding the harmful effects of radiation exposure and the risk of over-advancement.

Contact aspiration for basilar artery occlusion safely reduces the puncture-to-recanalization time.

OBJECTIVE: Effective thrombectomies in the posterior circulation remain controversial. Previous reports have demonstrated the superiority of contact aspiration in anterior circulation. Aspiration catheters and stent retrievers are often used alone on a global scale, while combined techniques are commonly used in Japan. This study evaluated the effect of first-line contact aspiration with other strategies for the treatment of basilar artery occlusion. METHODS: The primary outcome was the frequency of the first-pass effect, and the secondary outcome was the time from puncture to the first-pass effect. A multicenter observational registry including 16 Japanese stroke centers was used. Between December 2013 and February 2021, enrolled patients underwent endovascular thrombectomy for basilar artery occlusion. The efficacy of contact aspiration compared to other methods (including stent retrievers and combined techniques) was evaluated. RESULTS: Eighty-four patients were included, all of whom had achieved effective recanalization. Twenty-six patients were treated with contact aspiration, 13 with combined technique, and 45 with stent retrievers. The two groups: contact aspiration and non-contact aspiration, had different backgrounds. Both had similar frequencies of effective recanalization and first-pass effects. The contact aspiration group experienced better functional outcomes without statistical significance, while this strategy was significantly associated with a shorter puncture-to-recanalization time (38 vs. 55 minutes, P=0.036). In particular, in the 55 patients with the first-pass effect, multivariate Cox proportional hazard analysis showed that contact aspiration was significantly associated with a shorter time from puncture to first-pass effect, independent of age and etiology of large-artery atherosclerosis (hazard ratio 2.02, 95% confidence intervals 1.10-3.69, P=0.023). CONCLUSION: This study suggested that contact aspiration for basilar artery occlusion may shorten the puncture-to-first-pass effect, compared to stent retrievers and combined techniques.

Cross-Seal IDE Trial: Prospective, Multicenter, Single-Arm Study of the Cross-Seal Suture-Mediated Vascular Closure Device System.

BACKGROUND: An increasing number of interventional procedures require large-sheath technology (>12F) with a favorable outcome with endovascular rather than open surgical access. However, vascular complications are a limitation for the management of these patients. This trial aimed to determine the effectiveness and safety of the Cross-Seal suture-mediated vascular closure device in obtaining hemostasis at the target limb access site following interventional procedures using 8F to 18F procedural sheaths. METHODS: The Cross-Seal IDE trial (Investigational Device Exemption) was a prospective, single-arm, multicenter study in subjects undergoing percutaneous endovascular procedures utilizing 8F to 18F ID procedural sheaths. The primary efficacy end point was time to hemostasis at the target limb access site. The primary safety end point was freedom from major complications of the target limb access site within 30 days post procedure. RESULTS: A total of 147 subjects were enrolled between August 9, 2019, and March 12, 2020. Transcatheter aortic valve replacement was performed in 53.7% (79/147) and percutaneous endovascular abdominal/thoracic aortic aneurysm repair in 46.3% (68/147) of subjects. The mean sheath ID was 15.5±1.8 mm. The primary effectiveness end point of time to hemostasis was 0.4±1.4 minutes. An adjunctive intervention was required in 9.2% (13/142) of subjects, of which 2.1% (3/142) were surgical and 5.6% (8/142) endovascular. Technical success was achieved in 92.3% (131/142) of subjects. Freedom from major complications of the target limb access site was 94.3% (83/88). CONCLUSIONS: In selected patients undergoing percutaneous endovascular procedures utilizing 8F to 18F ID procedural sheath, Cross-Seal suture-mediated vascular closure device achieved favorable effectiveness and safety in the closure of the large-bore arteriotomy.

Pneumothorax risk reduction during CT-guided lung biopsy - Effect of fluid application to the pleura before lung puncture and the gravitational effect of pleural pressure.

PURPOSE: This study investigated strategies to reduce pneumothorax risk in CT-guided lung biopsy. The approach involved administering 10 ml of 1 % lidocaine fluid in the subpleural or pleural space before lung puncture and utilizing the gravitational effect of pleural pressure with specific patient positioning. METHOD: We retrospectively analyzed 72 percutaneous CT-guided lung biopsies performed at a single center between January 2020 and April 2023. These were grouped based on fluid administration during the biopsy and whether the biopsies were conducted in dependent or non-dependent lung regions. Confounding factors like patient demographics, lesion characteristics, and procedural details were assessed. Patient characteristics and the occurrence of pneumothoraces were compared using a Kurskal-Wallis test for continuous variables and a Fisher's exact test for categorical variables. Multivariable logistic regression was used to identify potential confounders. RESULTS: Subpleural or pleural fluid administration and performing biopsies in dependent lung areas were significantly linked to lower peri-interventional pneumothorax incidence (n = 15; 65 % without fluid in non-dependent areas, n = 5; 42 % without fluid in dependent areas, n = 5; 36 % with fluid in non-dependent areas,n = 0; 0 % with fluid in dependent areas; p = .001). Even after adjusting for various factors, biopsy in dependent areas and fluid administration remained independently associated with reduced pneumothorax risk (OR 0.071, p<=.01 for lesions with fluid administration; OR 0.077, p = .016 for lesions in dependent areas). CONCLUSIONS: Pre-puncture fluid administration to the pleura and consideration of gravitational effects during patient positioning can effectively decrease pneumothorax occurrences in CT-guided lung biopsy.

Inhibitory mechanisms of decoy receptor 3 in cecal ligation and puncture-induced sepsis.

Despite its high mortality, specific and effective drugs for sepsis are lacking. Decoy receptor 3 (DcR3) is a potential biomarker for the progression of inflammatory diseases. The recombinant human DcR3-Fc chimera protein (DcR3.Fc) suppresses inflammatory responses in mice with sepsis, which is critical for improving survival. The Fc region can exert detrimental effects on the patient, and endogenous peptides are highly conducive to clinical application. However, the mechanisms underlying the effects of DcR3 on sepsis are unknown. Herein, we aimed to demonstrate that DcR3 may be beneficial in treating sepsis and investigated its mechanism of action. Recombinant DcR3 was obtained in vitro. Postoperative DcR3 treatment was performed in mouse models of lipopolysaccharide- and cecal ligation and puncture (CLP)-induced sepsis, and their underlying molecular mechanisms were explored. DcR3 inhibited sustained excessive inflammation in vitro, increased the survival rate, reduced the proinflammatory cytokine levels, changed the circulating immune cell composition, regulated the gut microbiota, and induced short-chain fatty acid synthesis in vivo. Thus, DcR3 protects against CLP-induced sepsis by inhibiting the inflammatory response and apoptosis. Our study provides valuable insights into the molecular mechanisms associated with the protective effects of DcR3 against sepsis, paving the way for future clinical studies. IMPORTANCE: Sepsis affects millions of hospitalized patients worldwide each year, but there are no sepsis-specific drugs, which makes sepsis therapies urgently needed. Suppression of excessive inflammatory responses is important for improving the survival of patients with sepsis. Our results demonstrate that DcR3 ameliorates sepsis in mice by attenuating systematic inflammation and modulating gut microbiota, and unveil the molecular mechanism underlying its anti-inflammatory effect.

Understanding transcatheter edge-to-edge repair "knobology": Advanced catheter steering for different scenarios of transseptal puncture.

Following the introduction in the latest European and American guidelines, transcatheter edge-to-edge repair has become a valid alternative to surgery for ineligible patients. Among the available technologies, MitraClip (Abbott) was the first to be introduced for the percutaneous treatment of mitral regurgitation with the edge-to-edge technique. Although its safety and effectiveness has been widely demonstrated, the optimal procedural results are highly dependent from operators' experience. In this manuscript, we provide a full guide of advanced steering maneuvers of MitraClip in different scenarios of transseptal puncture.

Primary tracheoesophageal puncture in stapler-assisted laryngeal closure: a surgical modification.

With the advancements in the medical field, many innovations in medical devices have happened. Using a surgical stapler to close the laryngectomy defect without opening the pharynx is particularly advantageous in a total laryngectomy (TL). However, performing the tracheoesophageal puncture (TEP) during stapler closure of the larynx has not been widely advocated, due to the fear of complications related to the procedure.We treated two male patients with advanced glottic malignancy who underwent a TL. To restore their ability to speak, we performed a primary TEP and immediate voice prosthesis placement. After the TEP, we closed the larynx using a stapler. The surgical technique used in this procedure has been thoroughly explained.The use of a surgical stapler for pharyngeal closure during a TL has several advantages, particularly with regard to the duration of surgery. The current techniques appear to be promising in reducing TEP-related complications during stapler-assisted laryngeal closure.

The axillary vein puncture for implantable cardiac defibrillator implantation: 14 years of experience. Analysis of the results.

BACKGROUND: Axillary vein puncture (AVP) is a valid alternative to Subclavan vein puncture for leads insertion in cardiac implantable electronic device implantation, that may reduce acute and delayed complications. Very few data are available about ICD recipients. A simplified AVP technique is described. METHODS: All the patients who consecutively underwent "de novo" ICD implantation, from March 2006 to December 2020 at the University of Verona, were considered. Leads insertion was routinely performed through an AVP, according to a simplified technique. Outcome and complications have been retrospectively analyzed. RESULTS: The study population consisted of 1711 consecutive patients. Out of 1711 patients, 38 (2.2%) were excluded because they were implanted with Medtronic Sprint Fidelis lead. Out of 1673 ICD implantations, 963 (57.6%) were ICD plus cardiac resynchronization therapy, 434 (25.9%) were dual-chamber defibrillators, and 276 (16.5%) were single-chamber defibrillators, for a total of 3879 implanted leads. The AVP success rate was 99.4%. Acute complications occurred in 7/1673 (0.42%) patients. Lead failure (LF) occurred in 20/1673 (1.19%) patients. Comparing the group of patients with lead failure with the group without LF, the presence of three leads inside the vein was significantly associated with LF, and the multivariate analysis confirmed three leads in place as an independent predictor of LF. CONCLUSION: AVP, according to our simplified technique, is safe, effective, has a high success rate, and a very low complication rate. The incidence of LF was exceptionally low. The advantages of AVP are maintained over time in a population of ICD recipients.

[Optimization of the puncture treatment method for acute bacterial maxillary sinusitis]. / Optimizatsiya metoda punktsionnogo lecheniya ostrogo bakterial'nogo verkhnechelyustnogo sinusita.

OBJECTIVE: Optimization of the method of puncture treatment of acute bacterial maxillary sinusitis (ABMS) through the development of original devices for drainage of the maxillary sinus (MS). MATERIAL AND METHODS: Registration and comparative analysis of the results of puncture methods of treatment of 120 patients with ABMS using developed new original devices for drainage of MS with one channels and with two channels in comparison with the Kulikovsky's needle (KN) was carried out. Based on the results of the analysis, the effectiveness of the original devices was assessed. During the clinical study, patients were divided into two groups: in group I, patients underwent of the MS puncture using KN, in group II, using original devices. Groups I and II, depending on the absence or presence of a block of the natural anastomosis MS, was divided into subgroups A and B, respectively. After puncture of the MS, the pain syndrome was assessed by patients using Visual Analogue Scale (VAS) and by doctors - using Touch Visual Pain (TVP) scale. RESULTS: Our study showed that when puncturing the upper jaw with an original needle with one channels and with two channels, compared with the use of KN, there is a decrease in pain (the average VAS score was 1.5±0.3 and 1.7±0.3 points, respectively; the average TVP scale score was 0.9±0.2 and 1.8±0.3 points, respectively, the difference is significant, p≤0.05). Patients of subgroup IB were manipulated with two KN, patients of subgroup IIB manipulated using the original device with two channels without an additional needle (the average VAS score was 3.0±0.4 and 1.3±0.3 points, respectively; the average TVP scale score was 2.7±0.4 and 1.0±0.2 points, respectively, the difference is significant, p≤0.05). The doctors also assessed the devices used for puncture of the upper jaw. As a result of the study, the high efficiency and safety of using new original devices was established.
