Objective: To evaluate the early outcome of endovascular management of iatrogenic vascular injury (IVI).
Methods: From July 2002 to July 2010, 21 cases of IVI undergoing endovascular therapy were studied retrospectively. There were aorta injury (n = 2), peripheral artery injury (n = 11), visceral artery injury (n = 5), arteriovenous injury (n = 1) and venous injury (n = 2). And the procedures included endograft implantation (n = 15), intravascular embolization with coil (n = 4), combination of endovascular balloon intervention and percutaneous thrombin injection (n = 1) and balloon compression for hemostasis (n = 1).
Results: Technical success was achieved in all patients. And clinical success, defined as arrested hemorrhage and hemodynamic stabilization, was obtained in 20 (95.2%) patients. There was one case of intra-operative mortality. After the procedure, there were cerebral infarction (n = 2) and partial renal infarction (n = 1). Among them, 19 patients received a median follow-up period of 23.9 months (range: 4 - 84 months). Only 1 patient with iliofemoral vein stent implantation developed stent collapse and thrombosis at Week 3. There were no other complications.
Conclusion: Endovascular therapy is an effective procedure in the management of different types of IVI. Despite its encouraging early results, the long-term outcomes require further follow-ups and observations.

Urology Department, Ankara University Faculty of Medicine, 06480 Ankara, Turkey.
Background: We aimed to assess the rates of urethral stricture in transplant recipients, analyse patients with urethral strictures and present the posttreatment follow-up outcomes.
Methods: Between 2004 and 2023, a retrospective examination was conducted on kidney transplant recipients who underwent removal of ureteral catheters through retrograde cystoscopy at our facility or referred from external centres. The collected data encompassed patient demographics, pre- and posttransplant maximum urinary flow rate, specifics of stenosis, surgical interventions and outcomes from a 1-year follow-up.

A cerebral spinal fluid (CSF) leak from the anterior skull base is a challenging neurosurgical issue that requires prompt recognition and treatment. Options for treatment include medical and surgical repair. A systematic review was performed screening for both retrospective and prospective clinical studies evaluating the efficacy of acetazolamide in the event of CSF leaks of the anterior skull base.

Background: Identifying fetal growth restriction and distinguishing it from a constitutionally small fetus can be challenging. The umbilical vein blood flow is a surrogate parameter of the amount of oxygen and nutrients delivered to the fetus, providing valuable insights about the function of the placenta. Nevertheless, currently, this parameter is not used in the diagnosis and management of fetal growth restriction.

Background: Neuroleptic malignant syndrome (NMS) is a rare yet potentially fatal iatrogenic syndrome that can manifest with life-threatening symptoms. Theorized to be caused by the dopamine-blocking effects of certain medications, such as antipsychotics, or the withdrawal of dopaminergic agents, NMS is characterized by hyperthermia, autonomic instability, altered mental status, and muscular rigidity. Most treated cases resolve within weeks; however, in some cases, residual catatonic symptoms can persist for months after the resolution of acute hyperthermic and hypermetabolic symptoms.

Thyroid cancer is a common malignancy that requires comprehensive clinical evaluation prior to adequate surgical management. Over the last three decades thyroid surgery has tripled and is considered one of the most commonly performed procedures in general surgery. These procedures are associated with potential postoperative complications with significant deterioration in the patient's quality of life.
