Ultrasound-Guided Percutaneous Removal of Wooden Foreign Bodies in the Extremities with Hydro-Dissection Technique.

ABSTRACT:

Objective

We described the technique of ultrasound (US)-guided percutaneous removal of the foreign bodies (FB) with hydro-dissection in the radiologic department and presented video files of several cases.

Materials and methods

Four patients referred to the radiology department for US evaluation and US-guided percutaneous removal of the FBs in the upper and lower extremities between November, 2006 and November, 2013 were included in this study. The procedures started with US evaluation for the exact location and shape of the FB. A 5 mm-sized skin incision was made at the site of the nearest point from the FB where no passing arteries or tendons were present. We adopted a hydrodissection technique to separate the FB from adjacent tissue using a 2% lidocaine solution. Injected anesthetics detached the FBs from surrounding tissue and thereby facilitated removal. After the tip of the mosquito forceps reached the FB, the wooden FBs were removed.

Results

The mean time required for the entire procedure was approximately 20 minutes. There were no significant complications during the US-guided removal or long-term complications after the procedure. All 4 FBs were successfully removed from the soft tissue under US guidance.

Conclusion

Ultrasound-guided percutaneous removal of the FBs with hydro-dissection in the radiology department is a less invasive and safe method over surgical removal in the operating room. Additionally, the use of a guide wire and serial dilator may help minimize soft tissue injury and facilitate the introduction of forceps.

Removal of full-thickness vertical corneal stromal wooden foreign bodies: An innovative ab-interno technique.

Project description:A 28-year-old male presented with three full-thickness stromal wooden foreign bodies vertically oriented in the left cornea. An innovative intracameral approach was used. Paracentesis was done and healon was injected into the anterior chamber. Iris repositor was introduced into the anterior chamber and the area of foreign bodies was pushed up to compress the stroma. The wooden foreign body projected above the corneal surface and were picked up one by one using McPherson forceps. One of the foreign bodies has penetrated through the Descemet's membrane resulting a corneal perforation. A corneal perforation was confirmed by observing egress of the irrigating solution, injected into the anterior chamber through the paracentesis opening. The corneal perforation was sealed with corneal glue. He achieved 6/9 BCVA (OS) at 8 weeks and maintained it during18 months follow-up.

Evaluation and management of urethral foreign bodies and description of a novel ultrasound-guided catheter-based extraction technique.

Project description:There are numerous reports in the medical literature documenting urethral foreign bodies with nearly all cases found in men and often associated with underlying psychiatric disorders, autoerotic stimulation, and/or intoxication. Patients most commonly presented with localized penile pain, hematuria, dysuria, and occasionally obstruction. Although endoscopic removal by a urologist is often the first-line treatment, this report describes evaluation and management considerations and presents a novel extraction technique that may allow emergency physicians in consultation with urology to perform removal of some unusual urethral foreign bodies in the emergency department. We report a novel extraction technique using a pediatric foley catheter under ultrasound guidance that has been applied during multiple encounters with 2 individuals who have each presented multiple times at a single emergency department (ED) for evaluation because of urethral foreign body insertion. The foreign body materials have ranged from small pieces of rubber to cellophane to styrofoam and most commonly plastic utensils. Urologic extraction may be required in some cases, but ED removal can be considered. A final discussion of the creation of a multidisciplinary care plan to address resource use concerns also is described.

Minimally Invasive Surgery for the Removal of Posterior Intraocular Foreign Bodies.

Project description:This is a prospective clinical assay that included six patients who were diagnosed with penetrating corneal injury, traumatic cataract, and posterior segment intraocular foreign body (IOFB). Following anterior segment repair and extraction of traumatic cataract by clear cornea phacoemulsification, a standard 25-gauge transconjunctival pars plana vitrectomy was performed to find and release the IOFB. With active suction using a 25-gauge silicone tipped cannula, the foreign body was retrieved and safely placed in the anterior chamber. After stabilization of the anterior chamber with viscoelastic injection, IOFB extraction through the main phaco incision was easily performed, followed by placement of an intraocular lens. Of the six patients, 66.6% showed a significant improvement of visual acuity. No complications associated directly with the surgical procedure occurred. Our surgical technique is a safe alternative for handling and removing a posterior IOFB. There was no need for a scleral incision.

Percutaneous ultrasound-guided MANOS carpal tunnel release technique.

Project description:Ultrasound (US) is used with a minimally invasive cutting device to perform carpal tunnel release with a 3 mm wrist incision. US localizes tendons, arteries, and median nerve for safe introduction of the device into the wrist. The device is inserted in a blunt configuration under the flexor retinaculum, and a cutting wire is deployed that advances a 0.9-mm needle in the palm. The surgeon releases the flexor retinaculum from the inside out through the two skin punctures. Flexor retinaculum release is confirmed with US.

A Cross-Knotted Suture Basket Technique for Large Nonmagnetic Intraocular Foreign Body Removal.

Project description:Purpose:To report a novel technique of cross-knotted suture basket and to test its effectiveness in large nonmagnetic intraocular foreign body (IOFB) removal. Methods:A 7/0 Vicryl suture was cut in half and cross-knotted, and four ends were introduced into a 23G needle to form a basket. Pig eyes were used to set up the IOFB model, and the effectiveness of the suture basket in the removal of large nonmagnetic intraocular foreign bodies was tested. Results:Several modifications can be made to adapt to different situations. For the materials (stone, metal, glass, and wood) and shapes (irregular, spherical, and rectangle) of large IOFB tested, the cross-knotted suture basket successfully removed all kinds of IOFBs. Conclusion:The suture basket technique provides an accessible, safe, and effective alternative in large nonmagnetic IOFB removal. It can be adapted and interchangedand also worth's further clinical investigations.

Clinical Characteristics and Endoscopic Endonasal Removal of Foreign Bodies within Sinuses, Orbit, and Skull Base.

Project description:Foreign bodies within the sinuses, orbit, and skull base (FBSOS) are rare; hence, diagnosis and management guidelines are lacking. Endoscopic sinus surgery (ESS) removal is preferred because of the less invasiveness and minimal morbidity. This study was designed to summarize clinical experience with ESS management of FBSOS.We retrospectively reviewed clinical manifestations, imaging findings, treatment, and outcomes in consecutive patients with ESS removal of FBSOS between 2004 and 2015 at a tertiary academic medical center. The Chi-square test was performed to compare the infection rate between wooden and nonwooden FBSOS.There were 23 male and five female patients, with median age of 11 years. FBSOS were located within the sinuses (86%), orbit (75%), and skull base/intracranial region (46%). Wooden FBSOS had a significantly higher risk of infection (78%) compared with nonwooden FBSOS (5%, P < 0.05). Contrast-enhanced computed tomography (CT) plus three-dimensional reconstruction was sensitive in all cases. Twenty-seven (96%) FBSOS were removed by ESS alone, while 1 (4%) FBSOS was removed using the combined ESS and lateral cervical approach. Four of the nine intracranial penetrating FBSOS patients had intraoperative cerebrospinal fluid (CSF) leak and received endoscopic CSF leak repair. Twelve (43%) patients suffered complications (meningitis, diplopia, and vision loss).ESS is a minimally invasive, safe, and promising surgical approach for FBSOS removal. Contrast-enhanced CT is effective in preoperative diagnosis and intraoperative guidance. Wooden FBSOS had higher risk of infection, thus antibiotics are recommended.

Ultrasonography-guided removal of plant-based foreign bodies from the lacrimal sac in four dogs.

Project description:BACKGROUND:Dacryocystitis is an inflammation of the lacrimal drainage system. One of the most common causes of dacryocystitis in dogs is due to plant-based foreign bodies typically located in the lacrimal sac. The aim of this case series was to describe an ultrasonography-guided technique for dogs with plant-based foreign bodies in the lacrimal sac, as both a diagnostic and therapeutic tool. CASE PRESENTATION:Four dogs with clinically suspected plant-based foreign body in the lacrimal sac (with a total of five eyes affected) were evaluated by ultrasound with a multifrequency (8-14?MHz) linear probe. Under general anesthesia, the foreign body was removed using Hartmann alligator forceps inserted thorough the upper puncta. Ultrasound was used to guide the forceps in grasping the foreign body. Ultrasound was positive in four out of five lacrimal sac diseases. All identified foreign bodies were successfully removed by the ultrasonography-guided technique. CONCLUSIONS:The results show that ultrasound is a fast, non-invasive, and inexpensive method for the assessment of dacryocystitis due to foreign bodies in dogs. Ultrasound is also useful not only for identification, but also in the non-invasive removal of the foreign body from the lacrimal sac. To the best of authors' knowledge, this is the first study to describe the sonographic approach to the palpebral medial cantus as an initial diagnostic step in canine dacriocystitis.

Successful Percutaneous Coronary Intervention Using Intravascular Ultrasound-Guided Rewiring Technique in a Case of Spontaneous Coronary Artery Dissection Involving Left Main Bifurcation.

Project description:We herein describe a 49-year-old woman without significant cardiovascular risk factors who was transferred to our hospital with sudden onset of chest pain. The patient was diagnosed with non-ST-elevation acute myocardial infarction, and coronary angiography revealed a dissection at the proximal site of the left anterior descending artery (LAD) extending from the left main trunk (LMT) suggestive of spontaneous coronary artery dissection (SCAD). Because coronary flow was impaired after contrast injection and the patient had chest pain with ST elevation, urgent percutaneous coronary intervention was performed. The first guide wire was initially introduced from the LMT to the distal LAD, but intravascular ultrasound (IVUS) imaging revealed that the guide wire had passed through the true lumen of the left coronary artery ostium, false lumen at the ostium of the left circumflex artery, and true lumen of the distal LAD. We then reinserted another guide wire using an IVUS-guided rewiring technique from the true lumen of the LMT to the distal LAD. Finally, a drug-eluting stent was deployed to cover the dissected segment, and final coronary angiography revealed acceptable results with a patent left circumflex artery. This case report highlights that physicians should consider SCAD among the differential diagnoses in patients presenting with acute coronary syndrome, particularly in young women. In the present case, IVUS played a pivotal role in not only detecting the arterial dissection but also correctly introducing the guide wire into the true lumen.

Percutaneous Coronary Intervention in Spontaneous Coronary Artery Dissection: Role of Intravascular Ultrasound.

Project description:Spontaneous coronary artery dissection (SCAD) is a rare, life-threatening condition that usually manifests as an acute myocardial infarction. Diagnosing SCAD with conventional coronary angiogram can be challenging, particularly if the true lumen is severely narrowed. Our case highlights the challenges in performing successful percutaneous coronary intervention (PCI) in patients with SCAD. Intravascular ultrasound can prove to be a pivotal tool in the diagnosis and successful management of such cases by establishing the anatomic site of dissection, and confirming stent placement in the true lumen following PCI.
