Nexplanonectomy-the surgical removal of an embolized implanted contraceptive device: a case report and review of the literature.

BACKGROUND: Nexplanon implants are a common hormonal contraceptive modality. Though rare, these devices can embolize into the injured wall of the basilic vein, through the right heart, and finally wedge itself into a pulmonary artery. With adherence to the arterial wall over time, it becomes less amenable to endovascular retrieval. Patients may present with symptoms mimicking a pulmonary embolism, or without any symptoms at all. In asymptomatic cases, endovascular retrieval and/or surgery is required when patients wish to begin having children prior to biological inactivity. The current literature showed as little as nine case reports detailing lung tissue removal in the aim of reversing a patient's implanted contraceptive device. CASE PRESENTATION: A 22-year-old asymptomatic active-duty Caucasian female presented for elective outpatient Nexplanon removal. The suspicion of possible implant migration arose when it was discovered to be non-palpable in her left arm. After plain film x-rays failed to localize the implant, a chest x-ray and follow-up Computed Tomography (CT) scan revealed that the Nexplanon had migrated to a distal branch of the left pulmonary artery. Due to the patient's strong desires to begin having children, the decision was made for removal. Initial endovascular retrieval failed due to Nexplanon encapsulation within the arterial wall. Ultimately, the patient underwent a left video-assisted thoracoscopic surgery (VATS) for exploration and left lower lobe basilar S7-9 segmentectomy, which successfully removed the Nexplanon. CONCLUSIONS: Implanted contraceptive devices can rarely result in migration to the pulmonary vasculature. These radiopaque devices are detectable on imaging studies if patients and clinicians are unable to palpate them. An endovascular approach should be considered first to spare lung tissue and avoid chest-wall incisions, but can be complicated by encapsulation and adherence to adjacent tissue. A VATS procedure with single-lung ventilation via a double-lumen endotracheal tube allows surgeons to safely operate on an immobilized lung while anesthesiologists facilitate single-lung ventilation. This patient's case details the uncommon phenomenon of Nexplanon migration, and the exceedingly rare treatment resolution of lung resection to remove an embolized device.

A rare complication of tension band fixation of olecranon osteotomy: Distal migration of K-wire.

Tension band wiring (TBW) is one of the most commonly used fixation techniques to fix olecranon osteotomies. Hardware prominence has been the most commonly reported complication of TBW. However, distal migration of Kirschner (K)-wire after TBW fixation for olecranon osteotomy has not been reported. In this case report, we presented distal migration of K-wire detected nine months after initial surgery in a 46-year-old male patient. The patient was operated on for an intraarticular distal humerus fracture using an olecranon osteotomy. The osteotomy was fixed with TBW fixation. The patient missed routine follow-ups and presented to the outpatient clinic with a complaint of skin irritation at the elbow nine months after the surgery. On radiological examination, distal migration of one K-wire was detected. The K-wire was surgically removed without any complication. Physicians should be aware of possible complications of TBW and remove fixation after fracture union to avoid unexpected complications.

A Rare Case of Small Bowel Obstruction due to Migration of a Percutaneous Biliary Stent.

Biliary endoprostheses are widely used in the treatment of biliary lithiasis, malignant and benign strictures, and occasionally in long-lasting biliary fistulas. They can be placed endoscopically during endoscopic retrograde cholangiopancreatography and radiologically (percutaneous) when the endoscopic route is not feasible. Complications associated with the endoscopic placement of biliary endoprostheses are well described in the literature, with migration being the most common. Intestinal obstruction is a rare complication associated with the migration of these devices. There are no reports in the literature of this complication occurring after percutaneous placement. We present a case of a patient who arrived at the emergency department with ileal obstruction secondary to the migration and concurrent embedding of a covered stent placed radiologically to treat a biliary leak after surgery. The patient underwent diagnostic laparoscopic and ileal resection, revealing a lithiasic concretion at the tip of the stent, causing the small bowel obstruction.

Intrathoracic Needle Migration from the Mediastinum into the Thoracic Cavity.

Intrathoracic needles are rarely used in clinical practice. They can migrate within the body, injure large blood vessels and other organs, and cause severe complications. We report an interesting case of intrathoracic needle removal using video-assisted thoracoscopic surgery. The needle was inserted under the left clavicle, penetrated the mediastinum, and migrated into the right thoracic cavity. Although pneumothorax developed during the disease course, no severe complications were observed. This rare case illustrates the course of needle migration from the mediastinum into the thoracic cavity. Prompt imaging and surgical removal of foreign bodies are necessary in cases of intrathoracic foreign bodies.

Complicaciones perianales causadas por agentes modeladores inyectados en glúteos / Perianal complications caused by gluteal injection of modeling agents

En este reporte presentamos tres pacientes en quienes ocurrieron condiciones inflamatorias perianales tardías, luego de la administración de sustancias modeladoras no identificadas en los glúteos. El diagnóstico inicial y supuesto no fue correcto, ya que no se investigó durante la evaluación preliminar el antecedente de la administración de elementos modeladores. Recomendamos que los pacientes con patologías inflamatorias del ano, sobre todo aquellos cuyo curso es extraño, se les pregunte acerca de la administración de agentes modeladores en los glúteos. Esta práctica puede contribuir a la eficacia del diagnóstico de manifestaciones perianales caracterizadas por flogosis, que se presentan de forma inusual. (AU)

In this report we present three patients in which late perianal inflammatory conditions occurred after administration of unidentified modeling agents to the buttocks. The initial diagnosis was not correct because of the administration of modeling agents was not investigated during the initial eval-uation. We recommend inquiring patients with inflammatory pathologies of the anus, especially those whose course is unusual, about the adminis-tration of modeling agents to the buttocks. This approach can contribute to the efficiency of the diagnosis of perianal complaints characterized by inflammation, but rare in its appearance. (AU)

A Natural Flat Volumized Lips Filler Technique: Retrospective Analysis of 920 Patients.

BACKGROUND: Traditionally, hyaluronidase (HYAL) is used after hyaluronic acid (HA) injection to dissolve the undesired migration of product. OBJECTIVE: To describe a novel lip augmentation technique that uses HA and HYAL simultaneously in patients who previously had HA migration. METHODS AND MATERIALS: Nine hundred twenty female patients were included. In the first group ( n = 793), HA injections were performed in subcutaneous plane of the lips. In the second group who had previous product migration ( n = 127), 7.5 units of HYAL is injected in 4 points in ergotrid area before proceeding with HA injection. RESULTS: The medicis lip fullness scale scores after 2 weeks improved in all patients, while 92% of patients perceived the results as "very much improved" with Global Aesthetic Improvement Scale ( p ˂ .001). There was no difference between 2 groups regarding the patient satisfaction rates ( p ˃.05), while filler migration was seen in 0.2% ( n : 15) of patients in the first group during the follow-up period. CONCLUSION: The new vertical injection approach provided an increased vertical height, optimal eversion, and an incisor display on the lips. The simultaneous use of HYAL before HA injection seems to be a safe and effective practice in 1-stage treatment of the previously injected lips with filler migration into ergotrid area.

Intrapulmonary migration of a fractured acupuncture needle: a case report.

BACKGROUND: Acupuncture, a traditional Chinese medical treatment, has been gaining popularity over the years. However, it also presents certain risks. We report a case of a patient who discovered a foreign body in their lung several years after undergoing acupuncture. CASE PRESENTATION: A middle-aged woman presented to our hospital with chest pain. An X-ray revealed a needle-like foreign body in the middle lobe of her right lung. The patient had previously undergone acupuncture treatment for local pain in her lower back and lower extremities many years prior. Based on the imaging findings and her medical history, we hypothesized that the foreign body in her lung was a result of a dislodged acupuncture needle. Through preoperative 3-dimensional reconstruction and indocyanine green localization, we were able to locate the foreign body in the lateral segment of the right middle lobe. We successfully removed the foreign body via wedge resection, and the patient made a smooth recovery post-surgery. CONCLUSION: Acupuncturists and surgeons should remain vigilant about the potential risks associated with acupuncture.

Inferior Vena Cava Filter Long Term Complications and Retrieval Techniques: A Case Series and Literature Review.

INTRODUCTION AND IMPORTANCE: Long-term mechanical complications after inferior vena cava (IVC) filter placement include embedded or tilted filters, erosion of the vena cava, filter thrombosis. In the setting of caval thrombosis, patients may subsequently develop venous hypertension and post-thrombotic syndrome (PTS). Here we present three unique cases of IVC filter complications and surgical management. CASE PRESENTATION: A 30-year-old female presented with acute abdominal pain, revealing a duodenal perforation caused by an IVC filter eroding into her duodenum. A 42-year-old female with an IVC filter in place for 20 years due to a prior pulmonary embolism underwent laser-assisted retrieval of the filter due to concerns of caval adherence. A 48-year-old male with a history of DVT, venous stasis ulcer, and an IVC filter presented for filter retrieval. CLINICAL FINDINGS AND INVESTIGATIONS: The surgical techniques described in this report include complicated IVC filter retrieval, performed in cases of filter complications including migration, fracture, duodenal perforation and IVC thrombosis resulting in PTS. One case, requiring open retrieval, is explained and the surgical technique is provided. There are images and videos of these procedures to enrich the learning experience. INTERVENTION AND OUTCOMES: The surgical techniques described in this report include complicated inferior vena cava filter retrieval, performed in cases of filter complications including migration, fracture, duodenal perforation and IVC thrombosis. One case, requiring open retrieval, is explained and the surgical technique is provided. There are images and videos of these procedures to enrich the learning experience. RELEVANCE AND IMPACT: Endovascular retrieval of long-term complicated IVC filters is challenging, but it can be a safely performed in many patients. However, open surgery may be necessary in selected patients.

A Novel Microsnare and Microwire Coil Retrieval Technique.

Coil migration during endovascular embolization is a complication that can result in thromboembolic occlusion leading to potentially large infarcts if not removed. Microsnares are commonly used to remove migrated coils. Current techniques, however, struggle in cases where the microsnare is unable to loop over and secure a free end of the coil. We present a case in which a microsnare combined with a microwire successfully removed a migrated coil in a patient with a bleeding hepatic pseudoaneurysm post-embolization. This technique proved beneficial when traditional methods were insufficient, especially in small vessels or coil packs that cannot be snared. The synergy of the microsnare and microwire technique presents a promising solution for challenging migrated coil retrievals.

Spontaneous regression of migrated ventriculoperitoneal shunt catheter from scrotum to peritoneum: a case-based review.

OBJECTIVE: The incidence of scrotal migration of a ventriculoperitoneal shunt (VPS) catheter is rare and may lead to life-threatening visceral complications. Management requires prompt removal of the migrated portion of the shunt and closure of the scrotal sac. We report an interesting case of a young child who presented with asymptomatic unilateral swelling of his scrotum secondary to a migrated VPS catheter. A repeat X-ray prior to his surgery to remove the migrated catheter showed that the entire length of the distal VPS catheter was back in the peritoneal cavity. In view of this unusual phenomenon, the case is discussed in corroboration with published literature. METHODS AND RESULTS: A systematic search of publications in the English language is performed in PubMed and Google Scholar. Our findings show that there are 49 reported cases (including our patient) of scrotal migration of shunt catheters in patients less than 18 years old. There is only 1 other case of spontaneous resolution of shunt catheter from the scrotum. Favoured management of choice is repositioning the distal shunt catheter back into the peritoneal cavity and herniotomy in the same setting, if possible. Overall, the literature suggests this is a shunt-related complication that has a good prognosis if intervention is timely. CONCLUSION: Scrotal migration of a VPS catheter is a rare but potentially life-threatening complication in children. Our case report highlights the role of updated preoperative imaging and the need for consistent long-term shunt surveillance in children.

Outcomes of Hem-o-Lok clip migration at vesico-urethral anastomotic site post-robotic-assisted laparoscopic radical prostatectomy: a single centre experience.

BACKGROUND: Robotic-assisted laparoscopic prostatectomy (RALP) is the most preferred intervention for the management of prostatic malignancy worldwide. Hem-o-Lok clips (HOLC) are widely used for haemostasis and lateral pedicle ligation. These clips are prone to migrate and lodge at the anastomotic junction as well as inside the bladder causing lower urinary tract symptoms (LUTS) secondary to bladder neck contracture (BNC) or bladder calculi. The objective of this study is to describe the incidence, clinical presentation, management, and outcome of HOLC migration. METHODOLOGY: Retrospective analysis of the database of Post RALP patients who developed LUTS secondary to HOLC migration was done. Cystoscopy findings, number of procedures required, number of HOLC removed intra-operatively, and follow-up of the patients was reviewed. RESULTS: The incidence of HOLC migration requiring intervention was 1.78% (9/505). The mean age of the patient, BMI, Pre-operative Serum PSA were 62.8 years, 27.8 kg/m2, and 9.8 ng/mL, respectively. The mean duration of appearance of symptoms due to HOLC migration was 9 months. Two patients presented with Haematuria and 7 presented with LUTS. Seven patients required a single intervention while 2 required up to 6 procedures for recurrent symptoms secondary to recurrent HOLC migration. CONCLUSION: HOLC use in RALP may present with migration and associated complications. HOLC migration is associated with severe BNC and may require multiple endoscopic interventions. Severe dysuria and LUTS not responding to medical management should be treated using an algorithmic approach and there should be a low threshold for performing cystoscopy and intervention in these cases to improve outcomes.

[Intracardiac migration of the ureteral single-J : A case report and removal techniques]. / Migration intracardiaque de la sonde urétérale mono J : à propos d'un cas et techniques de retrait.

The techniques of derivation of the high urinary tract are indispensable in common practice for the management of ureteral obstructions. Like any surgical gesture, its techniques are not without complications; Among those common are hematuria, urinary incontinence, migration in the bladder and rupture of the probe. However, intracardiac probe migration has rarely been described. We report the case of a 68-year-old patient treated for cervical cancer who benefited from the rise of a bilateral single-J probe, admitted for accidental migration of the left probe into the heart. The diagnosis was made by plain abdominal X-ray and confirmed by thoraco-abdominal CT angiography. The patient benefited, in the catheterization room, from a withdrawal of the probe by endoscopic way and under radioscopic control successfully and without any incident.

Missing Bullets: Bullet Embolization Case Series and Review of the Literature.

PURPOSE: Bullet embolization is a rare but dangerous phenomenon. Based on the location of embolization, migration of bullets can cause limb or intra-abdominal ischemia, pulmonary infarction, cardiac valve injury, or cerebrovascular accident. Bullet emboli can present a diagnostic challenge given the varied nature of complications based on location of embolization, which may not coincide with the site of initial injury. The purpose of this study is to present several cases of bullet embolization from our busy urban trauma center and make recommendations for management. METHODS: We present 3 cases of bullet embolization seen in injured patients at our Level 1 trauma center. We describe our management of these injuries and make recommendations for management in the context of our institutional experience and comment on the available literature regarding bullet embolization. RESULTS: Two of our patients presented in extremis and required operative intervention to achieve stability. The intravascular missile was discovered intraoperatively in one patient and removed in the operating room, while the missile was discovered on postoperative imaging in another patient and again removed operatively after an unsuccessful attempt at minimally invasive retrieval. Our third patient remained hemodynamically stable throughout his hospitalization and had endovascular management of his bullet embolus. CONCLUSION: Bullet emboli present a challenging complication of penetrating trauma. We recommend removal of all arterial bullet emboli and those within the pulmonary venous system. In hemodynamically stable patients, we recommend initial attempts of endovascular retrieval followed by open surgical removal. We recommend open removal in cases of hemodynamic instability.

OFFICE MANAGEMENT OF OZURDEX IMPLANT DISLOCATION INTO THE ANTERIOR CHAMBER.

PURPOSE: To describe a novel office procedure that permits the repositioning of an Ozurdex implant from the anterior chamber back into the vitreous cavity. METHODS: Description of an office technique for Ozurdex repositioning using a 30-gauge needle. RESULTS: In both cases, the Ozurdex implant was successfully returned to the vitreous cavity. In Case 1, the patient's visual acuities 1 and 2 weeks after this were 20/70 and 20/40, respectively, and had no further complications. In Case 2, the patient returned 1 week later, with the implant remaining posterior and a visual acuity of 20/40. CONCLUSION: The success of this novel technique in these cases demonstrates the potential to avoid a surgical procedure in the event of Ozurdex implant migration to the anterior chamber, while at the same time allowing the Ozurdex implant to remain effective in the eye.

[A CASE OF PERIVESICAL ABSCESS CAUSED BY MIGRATION OF A FOREIGN BODY FROM THE INTESTINAL TRACT].

A 76-year-old woman was referred to our department because of high fever and bladder irritative symptoms. Computed tomography revealed the presence of a heterogeneous mass with indistinct borders on the left anterior wall of the bladder. The lesion contained a linear hyperdense shadow. We initially suspected malignancy, such as urachal carcinoma or soft-tissue sarcoma. However, upon review of previous computed tomography scans, it was confirmed that the linear hyperdense shadow had migrated from the intestinal tract to the bladder. Considering the possibility of abscess formation caused by a foreign body, we decided to perform a transurethral biopsy. The results of the pathological analysis showed abscess formation. The patient was diagnosed with perivesical abscess caused by accidental ingestion of a fish bone. Following the administration of antibiotics, the lesion markedly shrank. Although it is difficult to distinguish perivesical abscess from malignant disease, invasive treatment can be avoided by appropriate diagnosis based on imaging studies.

Migration of Broken Kirschner Wire to the Brachial Plexus after Fixation of Fracture Dislocation of the Acromioclavicular Joint.

A complication of Kirschner (K) wire fixation is the migration of the wire. We report a patient who had undergone fixation of a right clavicle fracture associated with acromioclavicular joint (ACJ) dislocation 15 years ago. He presented with features of pain and dysaesthesia in the right ulnar nerve dermatome on the movement of the neck and shoulder. Radiographic investigations showed a broken K-wire that had migrated to the lower brachial plexus. He underwent surgical removal of the K-wire and recovered uneventfully. We summarise the literature on K-wire migration reported following clavicle and ACJ injuries. Level of Evidence: Level V (Therapeutic).
