Objectives: We aimed to describe and compare the complications associated with different percutaneous radiologic gastrostomy (PRG) techniques. Methods: A retrospective and prospective observational study was conducted. Patients who underwent a PRG between 1995–2020 were included. Techniques: A pigtail catheter was used until 2003, a balloon catheter without pexy was used between 2003–2009 and a balloon catheter with gastropexy was used between 2015–2021. For the comparison of proportions, X2 tests or Fisher’s test were used when necessary. Univariate analysis was performed to study the risk factors for PRG-associated complications. Results: n = 330 (pigtail = 114, balloon-type without pexy = 28, balloon-type with pexy = 188). The most frequent indication was head and neck cancer. The number of patients with complications was 44 (38.5%), 11 (39.2%) and 54 (28,7%), respectively. There were seven (25%) cases of peritonitis in the balloon-type without-pexy group and 1 (0.5%) in the balloon-type with-pexy group, the latter being the only patient who died in the total number of patients (0.3%). Two (1%) patients of the balloon-type with-pexy group presented with gastrocolic fistula. The rest of the complications were minor. Conclusions: The most frequent complications associated with the administration of enteral nutrition through PRG were minor and the implementation of the balloon-type technique with pexy has led to a decrease in them.

A postnephrectomy renal acquired arteriovenous fistula (AVF) is a rare clinical entity that may cause high-output heart failure. Most of the cases are identified time along after surgery. We present a case of a postnephrectomy renal AVF treated with aortic customized stent-graft.

Solitary fibrous tumor (formerly known as hemangiopericytoma) is a rare soft tissue neoplasm, most frequently arising from the retroperitoneum and lower extremities. We present two cases of retroperitoneal solitary fibrous tumors diagnosed after surgical removal. We provide a literature review showing the basic clinical, pathologic and therapeutic features of these tumors.

Se presenta el caso clinico de una paciente de 39 anos con absceso tuboovarico diagnosticado por RM pelvica. Destacamos la importancia de esta tecnica de imagen para diferenciarlos de otros procesos pelvicos, principalmente neoplasicos

The persistent left-sided superior vena cava is a rare congenital venous anomaly. The existence of complications resulting from endovascular procedures in the context of this entity, requires knowledge of it. The evolution of imaging methods and the recent introduction of multidetector computed tomography allows easy diagnosis of this entity. We present a case of a 62 year-old-male with an incidental left-sided superior vena cava diagnosis as well as a short review of this uncommon entity.

Resumen Se presenta el caso clinico de una paciente de 39 anos, con hidrosalpinx diagnosticado por resonancia magnetica en el contexto de una enfermedad pelvica inflamatoria. Destacamos la importancia de esta tecnica de imagen para diferenciarlo de otros procesos pelvicos, principalmente neoplasicos.
