retroperitoneal AND (hematoma or haematoma or hematoncus) AND obstruction

Sickle cell anemia (SCA) is an autosomal recessive disorder caused by a mutation in beta globin gene. Hepatobiliary system is affected in 10-40% of patients with SCA and has a multifactorial etiology. The authors present a child with SCA and conjugated hyperbilirubinemia due to biliary obstruction. He underwent endoscopic retrograde cholangiopancreatography (ERCP) and biliary stenting, had complications of post sphincterotomy bleed, retroperitoneal hematoma and post laparoscopic cholecystectomy sepsis with acute sickle hepatic crisis...

Spontaneous retroperitoneal hematoma is rare and can cause duodenal obstruction. We report four cases of spontaneous retroperitoneal hematoma with duodenal obstruction, wherein endoscopic ultrasound was useful for diagnosis. The patients complained of vomiting with stable vital signs. Computed tomography, esophagogastroduodenoscopy, and endoscopic ultrasound findings were similar in all cases. Contrast-enhanced computed tomography revealed a low-density mass around the 2nd to 3rd part of the duodenum. Esophagogastroduodenoscopy showed an edematous, reddish, but non-neoplastic duodenal mucosa with stenosis of the lumen...

Hepatic Portal Venous Gas (HPVG) is the abnormal presence of gas in the portal venous system. It is associated with life-threatening conditions and is a sinister radiological sign. This case report aims to evaluate the significance of HPVG as a radiological sign. Our case involves a 49-year-old man who was admitted to the hospital following a one-day history of severe epigastric pain and haematemesis. Investigations showed extensive HPVG, gastric pneumatosis, a large retroperitoneal haematoma, and an obstructive lesion between the first and second part of the duodenum...

Spontaneous retroperitoneal haemorrhage (SRH) is rare. It may present with abdominal or back pain with or without haemodynamic instability. Aggressive resuscitation while investigating the cause of bleeding and providing haemostasis are the standard of care. Subsequent close monitoring is necessary to identify early complications.This study reports three patients who presented to our institution within the last 5 years with SRH from a ruptured pancreaticoduodenal artery (PDA) aneurysm. Each patient had a unique presentation, complications and treatment demonstrating the variability and complexity of SRH...

BACKGROUND: Catheter-directed thrombolysis (CDT) has been associated with rapid recovery of right ventricular (RV) function. The Bashir catheter was developed for enhanced thrombolysis in large vessels such as the pulmonary arteries (PAs) with lower doses of tissue plasminogen activator (tPA). OBJECTIVES: The aim of this study was to evaluate the efficacy and safety of tPA infused using a pharmacomechanical (PM) CDT device called the Bashir endovascular catheter in patients with intermediate-risk acute pulmonary embolism (PE)...

Central venous catheters (CVCs) are often crucial in managing severely ill patients, especially those in the intensive care unit. It is estimated that over 5 million CVCs are inserted per year in the United States. The internal jugular, subclavian, or femoral veins are the most used access sites. The catheter is advanced until its tip lies within the proximal third of the superior vena cava, the right atrium, or the inferior vena cava. Unfortunately, the use of CVCs is not without its drawbacks, and multiple immediate and delayed complications have been described...

A 41-year-old female with a previous history of chronic obstructive pulmonary disease (COPD) and polycythemia presented to the emergency department with worsening shortness of breath and cough which progressed to respiratory distress requiring mechanical ventilation. During her hospital stay, she developed abdominal distention followed by a fever and a four-point decrease in hemoglobin. A non-contrasted abdominopelvic CT scan was ordered which showed a very large retroperitoneal hematoma adjacent to the right colon with subtle active bleeding...

INTRODUCTION: Kidneys are one of the most commonly affected retroperitoneal organ in trauma cases despite its relatively well-protected location. Renal trauma occurs in 80-95% of urogenital trauma cases and 8-10% of abdominal blunt trauma. Renal trauma in hydronephrotic kidney due to ureteropelvic junction obstruction (UPJO) is a rare entity, despite of high risk of trauma urogenital due to large size and thin parenchyma. In this case we reported blunt renal injury with a congenital abnormality of the kidney...

Introduction: Pelvi-ureteric junction (PUJ) obstruction was traditionally treated with open pyeloplasty. In recent decades, the development of minimally invasive techniques, including laparoscopic and later robotic surgery, has transformed treatment. The transperitoneal approach has most commonly been undertaken, with a few institutions reporting outcomes of the retroperitoneal approach. We report our 10-year experience of retroperitoneal robotic-assisted laparoscopic pyeloplasty (R-RALP). Methods: A prospective database of 160 patients undergoing RALP between February 2010 and November 2019 was analyzed...

Objectives: To compare the therapeutic effect of retroperitoneoscopic dismembered pyeloplasty and open ureteropelvic junction plasty on the ureteropelvic junction obstruction (UPJO) in children. Methods: After the retrospective analysis of clinical data, 78 children with ureteropelvic junction stenosis treated from January, 2012 to June, 2018 were divided into two groups: OP (open pyeloplasty) group (38 cases) and LP (laparoscopic dismembered pyeloplasty) group (40 cases) according to the surgical methods...

BACKGROUND: The true incidence and natural history of renal artery aneurysm (RAA) remain unclear and still exists controversy over indication for treatment. Several techniques of conventional surgical reconstructions are described in literature, and more recently endovascular therapies have been reported with satisfying results and lower complication rate. This paper aims to investigate the outcomes of both endovascular and open repair of RAA achieved in a single institution involving 3 medical teams (urology, vascular surgery and neuroradiology)...

Endovascular repair has become the most frequent approach in the management of the ruptured infra-renal abdominal aorta aneurysm. When managing the ruptured patient with a significant retroperitoneal hematoma, abdominal compartment syndrome is often a consideration. Duodenal obstruction from the hematoma is rare and not typically a consideration. In the case of our patient, the intra-abdominal pressures were successfully managed conservatively. The large retroperitoneal hematoma, however, encased and obstructed the duodenum ultimately requiring a gastrojejunostomy...

BACKGROUND: Robot-assisted pyeloplasty (RALP) for patients with clinically symptomatic ureteropelvic junction obstruction (UPJO) is increasing and needs assessment. METHODS: Patients who underwent RALP for UPJO in two academic centres were included. Demographic and perioperative data were collected retrospectively. UPJO was evaluated by imaging pre- and post-surgery. Patients had follow-up consultations 3,6 and 12 months post-surgery. Global success was defined as a clinical response plus radiographic evidence of no further obstruction 3-months post-surgery...

A neutered female cat presented with a 9-day history of hyporexia and depression. The referring veterinarian had identified moderate non-regenerative anaemia, haematuria and suspected unilateral obstructive ureterolithiasis. Subsequent ultrasonography revealed moderate distension of the left renal pelvis with echogenic material, ureteral distension and ureterolithiasis. A partial ureteral obstruction was suspected. After 4 days of medical management, there was further distension of the renal pelvis with well-delineated echogenic material and an accumulation of perinephric fluid...

The perinephric space is the middle compartment of the retroperitoneum, containing the kidneys and adrenal glands. Differential considerations for diseases involving primarily the perinephric space differ from those arising from the kidney itself, show variant imaging features, and require identification and characterisation by interpreting radiologists-an imaging diagnosis can be suggested in many cases. Lymphangiomas are congenital cystic lesions that may contain lipid-laden chyle, which may be detectable on magnetic resonance imaging (MRI)...

Idiopathic retroperitoneal haematoma is a rare clinical entity; resulting duodenal obstruction is even more occult. It can pose a diagnostic challenge due to variable presentations. Timely management requires a high index of suspicion and a multidisciplinary approach. Surgery is indicated in patients refractory to conservative treatment and failure of endoscopic or interventional radiology options. We report an interesting case illustrating the rarity and severity of this condition, with a review of the literature...

Retroperitoneal hematoma is a potential complication of femoral venous access that rarely leads to bilateral ureteral obstruction. We present the case of a 73-year-old woman who underwent an ablation procedure for atrial fibrillation complicated by laceration of an aberrant obturator artery during femoral venous cannulation, leading to a compressive retroperitoneal hematoma, bilateral ureteral obstruction, acute renal failure, and renal forniceal rupture. The patient was successfully treated with embolization of the inferior epigastric artery and aberrant obturator artery, hematoma evacuation, and ureteral stent placement...

OBJECTIVE: To compare two percutaneous techniques used in the treatment of malignant obstructive uropathy-antegrade double-J stent placement (JJ stenting) and percutaneous nephrostomy-in terms of their cost-effectiveness, from the perspective of the Brazilian public health care system. MATERIALS AND METHODS: In this cost-effectiveness analysis, we employed decision-analytic modeling. We calculated material costs from 2017 factory prices listed by the Brazilian Pharmaceutical Market Regulatory Board (for medications) and published in the journal Revista Simpro (for medical devices)...

INTRODUCTION: Intestinal hematoma is usually observed after an abdominal trauma or in patients treated with anticoagulant therapy. Conversely, idiopathic bowel hematoma is very rare, being colon involvement sporadic with few reports in the Literature. PRESENTATION OF CASE: The Authors report a case of idiopathic spontaneous large bowel hematoma. A 48-year-old man was admitted for a thoraco-abdominal pain and signs of acute abdomen and fever. After ruling out heart diseases, a CT scan revealed a marked thickening of the ascending colon wall, obstructing the bowel lumen...

Introduction: The interest in laparoscopy in the treatment of ureteropelvic junction obstruction (UPJO) in children under 12 months of age remains controversial. The aim of this study is to evaluate feasibility and benefits of retroperitoneal laparoscopy (RL) compared to open surgery in this age group. Materials and Methods: Between January 2012 and May 2017, we performed 222 pyeloplasties: 144 by laparoscopy and 78 by open surgery. From 2012, the choice of operative technique was decided according to the laparoscopic experience of the surgeon; two surgeons operated laparoscopically on all children <12 months of age, while others operated using posterior lumbotomy (PL)...
