Methods to remove retained peripheral nerve catheters range from non-invasive techniques to open surgical procedures. This study reviews two cases requiring surgical intervention for catheter remnant removal after catheter breakage and presents a systematic review describing the diagnosis and treatment of retained perineural catheters. While still very rare, our case report and systematic review demonstrate that retained nerve catheters can occur as the result of kinking or knotting, but also from catheter breakage. We recommend risk mitigation strategies for providers placing or caring for patients with regional nerve catheters.

Hydrophilic polymer embolism (HPE) is a rare iatrogenic complication of the use of polymer-coated intravascular devices, which may affect several organ systems including the skin. Herein, we present a patient who developed a cutaneous eruption with associated neurologic manifestations secondary to localized HPE. This is a potentially underdiagnosed, life-threatening complication and physicians should consider HPE when evaluating skin eruptions in patients who have undergone endovascular procedures.

This report describes a very rare but life-threatening complication that occurred in a 43-year-old woman after an acupuncture (AC) for lumbago. The patient presented to the emergency department displaying symptoms indicative of shock. Physical examination revealed the absence of breath sounds on the right thoracic side, further investigations indicated the presence of a hemothorax. Emergency surgery was performed to evacuate the hemothorax and control bleeding from two intercostal veins. Although AC is often considered a gentle form of medicine, it is important to recognize that it can occasionally result in severe complications, especially when acupoints are used on the thorax.

Introduction: The Bacillus Calmette-Guérin (BCG) used as anti-tuberculous vaccine is also a well-known therapy for superficial urothelial cancer. Local or general side effects can occur, although it is generally well tolerated. Case: We present the case of a 65 year-old caucasian man consulting for gross hematuria and lower urinary tract symptoms. Magnetic resonance imaging (MRI) demonstrated a non-invasive urothelial carcinoma (NMIBC) and Prostate Imaging–Reporting and Data System (PIRADS) IV lesions. Transurethral resection of the bladder tumor revealed a non-invasive transitional cell carcinoma. Intravesical Bacillus Calmette Guerin (BCG) therapy was provided. After 6 intravesical instillations, the patient presented with prostato-epididymitis. Forthcoming BCG instillations were canceled, and cancer treatment was switched to epirubicine. Treatment with ethambutol, rifampicin and isoniazid was started with rapid resolution of the symptoms. Urinary and semen cultures grew Mycobacterium tuberculosis complex strain BCG. As prostate specific antigen (PSA) rose, prostate’s biopsies were performed showing extensive necrosis boarded by granulomas without signs of malignancy. Discussion: BCGitis is a rare complication in patients treated for non-invasive urothelial cancer. Several risk factors, local and systemic, should be considered prior to this immunotherapy. BCGitis (local or disseminated) or hypersensitivity reactions to BCG must be included in the differential diagnosis even if therapy was administered several years before the symptoms. Adequate treatment must be started as fast as possible to avoid serious complications.

Liver biopsy is the most accurate interventional procedure to diagnose hepatic diseases. According to the information provided by the Institute of Hygiene, 968 percutaneous liver biopsies were performed in Lithuania in 2022. The Lithuanian scientific literature does not, however, publish information on complications associated with this procedure. According to international literature, the frequency of complications after this procedure ranges from 2.4% to 9.5%. The most common are mild complications: hematomas, fever, pain at the biopsy site. Particularly rare are hemothorax, pneumothorax, damage to the organs of the thoracic and abdominal cavity, which occur in up to 0.04% of cases. This article presents an extremely rare complication – liver biopsy induced hemothorax, whose success was determined by early diagnosis and timely surgical intervention. [ABSTRACT FROM AUTHOR]

IntroductionIntra-abdominal gossypiboma, a cotton-based retained foreign body after an abdominal surgery, is associated with various clinical manifestations and complications. Its infrequent occurrence and unpredictability make its early diagnosis particularly challenging. We herein present an atypical case of intra-abdominal gossypiboma mistaken for a jejunal tumor.Case presentationA 33-year-old female presented to the emergency room with an acute episode of progressive abdominal pain and distention, nausea, and vomiting for 20 hours. She had undergone an urgent cesarean section due to fetal tachycardia seven years prior. The initial diagnosis of small bowel obstruction (SBO) due to a jejunal tumor was established by computed tomography. Subsequent to successful medical management of the SBO, a laparoscopy-assisted resection of the mass and the adherent jejunal segment was conducted, culminating in a primary side-to-side jejunojejunostomy. Examination of the excised tissue revealed an approximately spherical fibrous mass, 6 × 6 × 5 cm in dimension, embedded in the jejunal wall, housing a 20 × 20-cm gauze. Postoperative recovery and routine follow-up ensued without complications.ConclusionIn light of this case, the need for clinicians to maintain an elevated awareness and suspicion of gossypiboma should be accentuated when evaluating an intra-abdominal mass, especially in patients with a prior history of high-risk laparotomy. Laparoscopic surgery stands out as a technically proficient and minimally invasive strategy for diagnosing and treating intra-abdominal gossypiboma. Besides, it is imperative to emphasize the importance of meticulous surgical procedures and postoperative protocols to prevent such oversights, reaffirming the need for consistent intraoperative counts and checks of surgical items.

Abstract Although rare, right coronary artery (RCA) injury is a serious complication of tricuspid annuloplasty (TAP) and warrants close attention. We report a case of ST elevation myocardial infarction secondary to iatrogenic RCA occlusion during minimally invasive cardiac surgery (MICS). Electrocardiography (ECG) revealed ST segment elevation in lead II. Transesophageal echocardiography (TEE) revealed inferior wall hypokinesis after cardiopulmonary bypass, and coronary angiography revealed peripheral RCA occlusion. Intraoperatively, we detected an atrioventricular groove deformity during the second surgical procedure. Wall motion and ECG abnormalities showed normalization after TAP was reestablished. Vigilant monitoring using TEE and ECG is important to detect intraoperative myocardial ischemia during MICS-TAP.

Objective: Bone marrow biopsy complications are rare. Our aim is to study the association of improper palpation-guided iliac biopsy tract with complications. Materials and methods: This is a retrospective study of adult patients who underwent iliac bone marrow biopsy without image guidance at our hospital from January 2019 to January 2021, and have cross-sectional radiologic imaging of the pelvis within 30 days following the procedure. Electronic health records were reviewed for clinical data. Two radiologists reviewed images of the pelvis for assessment of biopsy tract and complications. Results: A total of 443 procedures were included in 309 patients, mean age 53.4 ± 18.1 years, 112 females (36.2%). In addition, 332 tracts were proper (75%), 97 improper (22%), and 14 unidentified (3%). All 11 complications occurred in procedures with improper tracts; nine bleeding, one fracture, and one facet joint injury. Improper tract was significantly associated with complications (p <.001). There was no statistically significant association between platelet count, international normalized ratio, antiplatelet use and anticoagulant use, and presence of complications (p >.05). Body mass index and subcutaneous fat thickness overlying posterior superior iliac spine were not associated with improper tract (p >.05). Procedures performed by providers with ≤ 12 months' experience were significantly associated with improper tract (p <.001) and hence associated with complications (p =.007). Conclusion: Improper tracts were common in palpation-guided iliac bone marrow biopsy and significantly associated with complications. No complications were encountered in proper tract procedures. Procedures performed by providers with ≤ 12 months' experience were significantly associated with improper tract and complications. [ABSTRACT FROM AUTHOR]

Diaphragmatic hernias have classically been reported due to congenital birth defects and blunt or penetrating trauma. We present a rare case of an intrapericardial diaphragmatic hernia after left-sided pericardial window surgery for chronic pericardial effusions. A 59-year-old female with a background of systemic lupus erythematosus and recurrent pericardial effusions underwent subxiphoid placement of a pericardial-peritoneal window. Postoperatively, she reported exertional shortness of breath. Imaging revealed a diaphragmatic hernia in the pericardial cavity. Open adhesiolysis between the abdominal organs and the heart was performed via a thoracoabdominal approach followed by suture and mesh repair of the defect. The postoperative course was uneventful. Pericardial hernias are rare, with few published cases. Their etiologies can be traumatic, iatrogenic, or congenital, with variable, non-specific symptoms that may occur at any time after the inciting event. With the potential for significant cardiac compromise, clinicians should be aware of this rare diagnosis, and surgical repair must be prioritized. This case documents the successful surgical management of this rare complication. Careful multidisciplinary planning is essential for surgical repair and should be tailored to patient-specific factors., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Purpose: To report a case of iatrogenic vitrectomy trochar-induced cyclodialysis cleft successfully treated with intraoperative argon endolaser. Observations: A 68-year-old Caucasian male with a history of high myopia underwent pars plana vitrectomy to clear symptomatic vitreous opacities but developed early postoperative hypotony that was recalcitrant to medical management for the first 6 postoperative months. Intraoperative gonioscopy demonstrated a cyclodialysis cleft and argon endolaser was applied to close the cleft. Conclusions and Importance: Endolaser is an effective treatment for cyclodialysis clefts and intraoperative gonioscopy allows direct visualization of the cleft in a controlled operating room setting. Placement of vitrectomy ports should be done with care in high myopes to avoid accidental piercing of the ciliary body and inducing a cyclodialysis cleft.

Iatrogenic coronary artery fistula (CAF) can occur following acute myocardial infarction, percutaneous coronary intervention (PCI) procedures, and heart surgery. Iatrogenic CAF linked to PCI has a low incidence rate. Early diagnosis and treatment are crucial when an iatrogenic fistula develops, as it may lead to cardiac tamponade, myocardial infarction, or death. In this report, we present a case of iatrogenic CAF secondary to coronary perforation caused by guidewire-induced trauma, followed by stent implantation and balloon inflation in the context of acute coronary syndrome (ACS). It was successfully managed through prolonged balloon inflation within the previously implanted stent just prior to the rupture zone., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Iatrogenic bladder rupture is a rare yet serious complication associated with orthopedic surgical procedures, particularly those involving the modified Stoppa (MS) approach for acetabular fractures. We present a case of a 65-year-old patient who experienced iatrogenic bladder rupture during surgery for acetabular fracture fixation using the MS approach. Despite the challenges posed by this complication, prompt diagnosis and repair during the same surgical intervention led to favorable outcomes. Our case underscores the importance of perioperative vigilance in detecting and managing such injuries to mitigate the risk of urinary tract complications and late infections. Understanding the anatomical nuances and employing meticulous surgical techniques are essential for minimizing the risks associated with the MS approach., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Abstract An 8‐year‐old 24.6 kg mixed breed dog underwent bronchoscopy for evaluation of a persistent progressive cough. Bronchoscopy documented a markedly thick and irregular, cobblestone appearance of the mucosa. A bronchoscopic biopsy was obtained; immediately after the biopsy, a large amount of hemorrhage poured from the endotracheal tube. Multiple efforts to control the hemorrhage were unsuccessful and the dog suffered a cardiopulmonary arrest and could not be revived. A necropsy was performed, which was significant for pallor, evidence of prior heartworm disease, prominent bronchial arteries, and erosion of the submucosal vessels at the site of the biopsy. The cause of death was hemorrhage associated with transbronchial biopsy of an enlarged bronchial artery associated with heartworm disease. This report describes a rare complication of a routine diagnostic procedure.

The WHO Global Patient Safety Challenge: Medication Without Harm recognises medication-related harm (MRH) as a global public health issue. Increased life-expectancy coupled with multimorbidity and polypharmacy leads to an increased incidence of MRH, especially in older adults: at a cost of approximately £400 million to the National Health Service (NHS) in England. Harm from medicines has long been recognised by geriatricians, and strategies have been developed to mitigate harm. In general, these have focused on the challenges of polypharmacy and appropriateness of medicines, but impact on the quality of life, clinical and economic outcomes has been variable and often disappointing. The problem of MRH in older adults will continue to grow unless a new approach is adopted. Emerging evidence suggests that we need to take a broader approach as described in our conceptual model, where well-recognised physiological changes are incorporated, as well as other rarely considered psychosocial issues that influences MRH. Parallels may be drawn between this approach and the management of geriatric syndromes. We propose there must be a greater emphasis on MRH, and it, of itself, should be considered as a geriatric syndrome, to bring the spotlight onto the problem and to send a clear signal from geriatric experts that this is an important issue that needs to be addressed using a co-ordinated and tailored approach across health and social care boundaries. This requires a more proactive approach to monitor and review the medicines of older adults in response to their changing need. [ABSTRACT FROM AUTHOR]

Hemisection is the separation of the whole tooth from the mesial to distal in the upper molars and premolars and from the buccal to lingual in the lower molars, and removal of the pathological root together with the crown. Hemisection is an appropriate treatment option when caries, resorption, iatrogenic complication or periodontal damage is limited to one root and the other root is relatively healthy. Hemisection of the affected tooth helps to preserve alveolar bone which surrounding the tooth structure and supports fixed dentures. Therefore, when a molar tooth should be extracted only because of damage at one root, hemisection or root amputation treatment alternatives should be kept in mind. This case series describes hemisection as a successful treatment method to recover teeth with iatrogenic complications and irretrievable root caries were limited to single root.

Our two case reports represent endovascular treatment of feared and potentially devastating iatrogenic arterial injuries during orthopedic surgery of the hip and knee. First case describes an endovascular reconstruction of pseudoaneurysm of popliteal artery after total knee replacement. A selfexpandable stentgraft was implanted via endovascular approach and no other complications appeared postoperatively. Second case conveys a story of female patient with total hip endoprosthesis complicated by periprosthetic fracture. Upcoming operation resulted in superficial femoral artery occlusion, which was treated with thrombaspiration and selfexpandable stentgraft implantation. This patient however, owing to overall frailty, expired later by causes unrelated with endovascular procedure. Our paper briefly points that endovascular treatment is highly effective and safe method and should be considered as the option of the first choice. [ABSTRACT FROM AUTHOR]

Vasectomy is a surgical procedure for male sterilization. Despite being a minor operation, complications such as haematoma, infection and failed sterilization may occur. Urethrocutaneous fistula is a surgical complication usually occurring after hypospadias repair or secondary to treatment of a urethral growth. We present a case of iatrogenic urethrocutaneous fistula after vasectomy in a 32-year-old gentleman, treated successfully by non-operative management with suprapubic urinary diversion and to our knowledge is the first such case to be reported in literature.

Summary Yttrium-90-Ibritumomab Tiuxetan (Zevalin ® ) is used in the treatment of non- Hodgkin's lymphoma. Extravasation is an iatrogenic complication that is fortunately rare. However, the treatment of this complication is often complex due to the risk of extensive skin necrosis and unpredictable evolution of localized irradiation. This vesicant drug requires emergency management when extravasation occured. Radiations burns have specificities. Therefore, wound coverage involves specific plastic surgical techniques. Here, we report the case of a man presenting a chronic and extensive skin necrosis of upper arm treated with an antero-lateral thigh free flap. Moreover, we compare our experience of Zevalin ® extravasation management to other past publications and propose recommendations to prevent this unacceptable complication. [ABSTRACT FROM AUTHOR]

The article describes a case of iatrogenic complication as a result of the 26 tooth extraction in 50 year old female patient.

Chilaiditi syndrome is an occasional radiographic anomaly characterized by the interposition of the bowels between the liver and the diaphragm. The presence of Chilaiditi syndrome can cause serious problem on percutaneous endoscopic gastrostomy (PEG) procedure, because the anomalous position of the transverse colon can obstruct the procedure and might lead to occurrence of complications. Our report describes a PEG-induced gastro-colo-cutaneous fistula in a patient with Chilaiditi syndrome which resulted in minimally invasive laparoscopic gastrostomy. As most patients who need a PEG placement have impaired consciousness, the majority of PEG-related complications are overlooked or discovered long after the procedure. However, we recognized the complication immediately after the PEG procedure and successfully treated by laparoscopic surgery.

Despite the increasing use of carbon dioxide for endoscopies during the last years, ambient air is still used. The amount of air depends on several factors such as examination time, presumable diameter of the endoscope channel and of course active use of air by the operator. Although endoscopic complications due to ambient air in the gastrointestinal (GI) tract are a rare observation and mostly described in the colon, we report five cases in the upper GI tract due to insufflating large amounts of air through the endoscopes. All 5 patients needed an emergency upper endoscopy for acute presumed upper GI bleeding. In two cases both esophageal variceal bleeding and ulcer bleeding were detected; the fifth case presented with a bleeding due to gastric cancer. Due to insufflation of inadequate amounts of air through the endoscope channel, all patients deteriorated in circulation and ventilation. Two rumenocenteses and consecutively three laparotomies had to be performed in three patients. In the other two, gastroscopies had to be stopped for an emergency computed tomography. All critical incidents were believed to be a consequence of a long-lasting examination with use of too much air. Therefore in emergency situations, endoscopies should be performed with either submersion, low air flow pumps or even better by the use of carbon dioxide.
