Abstract
Type 1 diabetes mellitus (T1DM) is a chronic autoimmune disorder characterized by the destruction of insulin-secreting beta cells in the pancreas, resulting in metabolic disturbances and long-term complications. While subcutaneous insulin remains the primary approach for achieving normoglycemia, pancreatic transplantation has emerged as an effective intervention for long-standing T1DM, providing insulin independence and normalized glycosylated hemoglobin levels. However, complications associated with pancreatic transplantation are frequent, necessitating thorough evaluation using diverse imaging modalities. This manuscript presents an overview of complications encountered with pancreatic transplantation, including vascular complications such as arterial and venous graft thrombosis, vessel stenosis, pseudoaneurysm, arterio-enteric fistula, and arteriovenous malformations. Additionally, the manuscript discusses other associated complications such as pancreatitis, pseudocyst formation, fistulas, pseudo-thrombosis of the iliac vein, post-transplantation lymphoproliferative disorder, and fluid collections. The integration of various imaging modalities plays a crucial role in diagnosing and managing these complications, with interventional radiologists assuming a vital role in employing image-guided procedures. Moreover, the manuscript explores pancreatic islet cell transplantation as a promising cellular-based therapy for T1DM, offering stable long-term glycemic control and decreased reliance on exogenous insulin in a significant proportion of recipients. This minimally invasive procedure involves the image-guided transcatheter infusion of islet cells obtained from deceased donors into the recipient's liver. The importance of interventional radiologists in managing complications related to pancreatic transplantation is underscored, with endovascular or image-guided approaches being utilized to address the diverse spectrum of encountered complications. Furthermore, the potential of islet cell transplantation as a minimally invasive alternative to traditional pancreatic transplantation is emphasized, as it offers the prospect of preventing many associated complications.

Abstract
Diabetes management has continued to evolve with new treatments and technology. This article discusses the approach to evaluation and management of two distinctive subsets of patients: (1) patients who manage their diabetes with an insulin pump (artificial pancreas) and (2) patients who have received a pancreas transplant. The most current literature is reviewed and pearls and pitfalls distinctive to these two patient populations are discussed. Relevant diagnostics are reviewed with emphasis on recognition of complications faced in the emergency department management of these unique patient populations.

Abstract
Pancreatic transplantation is an established treatment for patients with type 1 diabetes patients and select type 2 diabetes patients, with excellent survival rates as graft health is evaluated through regular imaging and early detection of complications. Amongst the various imaging methods that may aid in diagnosis of pancreatic transplant complications, ultrasound is a widely available, quick, portable, and cost-effective technique, often used as the sole method to assess for pancreatic transplant complications. When assessing a patient with a pancreatic transplant, the radiologist should be methodical in assessing the vasculature, the pancreatic parenchyma, and the peripancreatic regions. Complications can be categorised based on time from transplant and type of complications, and include vascular, parenchymal, and enteric/anastomotic complications. Doppler has a major role in the diagnosis of vascular complications including arterial and venous thrombosis, arterial stenosis, pseudoaneurysms, and haematomas. Pancreatic complications include rejections and pancreatitis, and are often diagnosed through a combination of clinical, laboratory, and imaging findings, such as pancreatic heterogeneity or the presence of pancreatic pseudocysts. Enteric/anastomotic complications include leaks and bowel obstructions, and may require cross-sectional imaging in addition to ultrasound. This review covers the most common and high-impact vascular, parenchymal, and enteric/anastomotic complications that should be considered in every radiologist's search pattern when assessing a pancreatic graft, as well as their respective postoperative timeframes.

Abstract
Pancreatic graft thrombosis (PAT) is a major surgical complication, potentially leading to graft loss. The recently proposed Cambridge Pancreas Allograft Thrombosis (CPAT) grading system provides diagnostic, prognostic and therapeutic recommendations. The aim of the present study was to retrospectively assess computed tomography angiography (CTA) examinations performed routinely in simultaneous pancreas-kidney (SPK) recipients to implement the CPAT grading system and to study its association with the recipients' outcomes. We retrospectively studied 319 SPK transplant recipients, who underwent a routine CTA within the first 7 postoperative days. Analysis of the CTA scans revealed PAT in 215 patients (106 grade 1, 85 grade 2, 24 grade 3), while 104 showed no signs. Demographic data of the patients with and without PAT (thrombosis and non-thrombosis group) were not significantly different, except for the higher number of male donors in the thrombosis group. Pancreatic graft survival was significantly shorter in the thrombosis group. Graft loss due to PAT was significantly associated with grade 2 and 3 thrombosis, while it did not differ for recipients with grade 0 or grade 1 thrombosis. In conclusion, the CPAT grading system was successfully implemented in a large series of SPK transplant recipients and proved applicable in clinical practice.

Abstract
A 51-year-old patient with type I diabetes and end-stage renal disease was qualified for a simultaneous kidney and pancreas transplant. The procedure was performed in a typical manner: arterial anastomosis to the right common iliac artery, the graft's portal vein with inferior vena cava, and side-to-side duodenal intestinal anastomosis. The kidney was implanted retroperitoneally. Six months after the transplant, the patient reported pain in the right lower abdomen, and imaging examinations revealed arterial anastomosis. Reconstruction of the right common iliac artery was performed with a Gore-Tex prosthesis and the pancreatic artery reanastomosed to the right external iliac artery. After the surgery, the function of the transplanted pancreas deteriorated, the level of C-peptide was decreased, and the patient required low doses of insulin. After another 8 months, the imaging studies revealed an aneurysm located in the bifurcation of the aorta up to the anastomosis of the pancreatic graft artery with the iliac artery. The patient was qualified for the implantation of an endovascular of 2 prosthesis, which improved the graft's function. After another 2 months, the presence of an aneurysm at the endovascular prosthesis was found again. The patient was requalified for endovascular prosthesis implantation. Currently, there is no aneurysm but the function of the pancreas graft is impaired, though the kidney graft function is good. Patients after simultaneous kidney and pancreas transplant are a group of patients with an increased risk of vascular complications. Treatment should take place in a multidisciplinary center.

Contrast extravasation on computed tomography angiography in patients with hematochezia or melena: Predictive factors and associated outcomes. Diagn Interv Imaging 2021; 103:177-184. [PMID: 34657834 DOI: 10.1016/j.diii.2021.09.006] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Revised: 09/23/2021] [Accepted: 09/23/2021] [Indexed: 12/18/2022]
Abstract
PURPOSE The purpose of this study was to identify variables associated with extravasation on computed tomography angiography (CTA) in patients with hematochezia/melena and compare the outcome of patients with extravasation on CTA to those without extravasation. MATERIAL AND METHODS Ninety-four patients (51 men, 38 women; mean age, 69 ± 16 [SD] years) who underwent CTA within 30 days of hematochezia/melena were included. Variables associated with extravasation on CTA were searched using univariable and multivariable analyses. Outcomes of patients with visible extravasation on CTA were compared with those without visible extravasation. RESULTS One hundred and one CTA examinations were included. Extravasation was observed on 26/101 CTA examinations (26%). At multivariable analysis the need for vasopressor drugs (odds ratio [OR], 7.6; P = 0.040), high transfusion requirements (> 2 blood units) (OR, 7.1; P = 0.014), CTA performed on the day of a hemorrhagic event (OR, 46.2; P = 0.005) and repeat CTA (OR, 27.8; P = 0.011) were independently associated with extravasation on CTA. Extravasation on CTA was followed by a therapeutic procedure in 25/26 CTAs (96%; 26 patients) compared to 13/75 CTAs (17%; 68 patients) on which no extravasation was present (P < 0.001). No patients (0/26; 0%) with contrast extravasation on CTA died while 8 patients (8/61; 13%) without contrast extravasation died, although the difference was not significant (P = 0.099). CONCLUSION Extravasation on CTA in the setting of hematochezia or melena is especially seen in clinically unstable patients who receive more than two blood units. Presence of active extravasation on CTA leads to more frequent application of a therapeutic procedure; however, this does not significantly affect patient outcome.
