Pelvic Pseudoaneurysm as a Cause of Severe Hematuria After Robotic-assisted Radical Prostatectomy

To alert the medical society regarding that hematuria after radical prostatectomy can be caused by pelvic pseudoaneurysm. Case report of a 61-year-old male underwent extraperitoneal robotic-assisted radical prostatectomy. He was readmitted on the 15th POD due to gross hematuria with resolution after bladder irrigation. It returned on the 21st POD. The CT angiography evidenced the pseudoaneurysm of the left internal iliac artery. Selective embolization was effectively performed, with no additional bleeding or pelvic ischemia. Endovascular therapy is the preferred method of treatment. The pelvic pseudoaneurysm is a rare, but serious complication that can cause severe bleeding. In our experience, we had 3 cases of persistent hematuria caused by pelvic pseudoaneurysm after 1810 robotic-assisted radical prostatectomy.

Application of interventional embolization in the treatment of iatrogenic pseudoaneurysms.

The present study aimed to investigate the clinical effectiveness and safety of endovascular embolization for the treatment of pseudoaneurysm secondary to previous abdominal and pelvic surgery or radiological percutaneous abdominal procedure. A retrospective review was performed on all patients with abdominal and pelvic pseudoaneurysm confirmed by CT angiography or digital subtraction angiography and treated with endovascular embolization. Different techniques of embolization with coils were applied and the outcomes, including clinical effectiveness and safety, were assessed. A total of 31 patients with a total of 32 pseudoaneurysms were included in the present study. Of these pseudoaneurysms, 23 were from the main trunks and branches of the gastroduodenal artery, 5 were from the splenic artery, 2 were from the common hepatic artery, 1 was from the right hepatic artery and 1 was from the right internal iliac artery. There were no serious complications observed and there was no occurrence of re-bleeding following embolization. The embolization of the pseudoaneurysms was successful in all patients. In conclusion, endovascular embolization is a safe and effective method for the treatment of secondary iatrogenic pseudoaneurysm in the abdomen and pelvis.

Institutional Review of Hemorrhagic Pelvic Emergencies Effectively Managed with Percutaneous Arterial Embolization.

Objective: Our aim was to review the results of pelvic arterial embolization (PAE) performed in the interventional radiology suite.Method: The data of all patients in whom pelvic angioembolization was performed was collected from July 2011 to June 2017. Procedures were performed by an experienced interventional radiologist. The clinical and laboratory data, as well as the outcome data, were obtained from the medical records of our hospital. The following parameters were collected for each patient, including the age, gender, presenting symptoms, site of bleeding, catheters used for embolization, material used for embolization, previous computed tomography (CT) scan and/or focused assessment with sonography for trauma (FAST) ultrasound, average hemoglobin before the procedure, and patient clinical status on discharge.Result: A total of 37 patients underwent pelvic angiography for acute hemorrhage at our institution. They had contrast blush, active extravasation, or abnormal vascularity from the branches of the internal iliac artery and underwent therapeutic transcatheter embolization. A total of 29 patients (78.3%) were male and 8 (21.7%) were female. The average age was 30.0 years (range: 6-90 year). Of these, 16 patients (43.2%) presented with road traffic accidents (RTAs), six with gunshot injuries (16.2%), six with iatrogenic injuries (16.2%), four with a history of a fall (10.8%), two with bomb blast injuries (5.4%), one with a history of a glass injury (2.7%), one had a history of a roof falling on her during an earthquake, and one patient had a pelvic pseudoaneurysm secondary to an abscess. The type of embolic material used for embolization included coils in 16 patients, polyvinyl alcohol (PVA) particles were used in eight patients, both PVA particles and coils were used in 11 patients, and glue was used in one patient. All were successfully embolized. Thirty-four were discharged while three patients expired during the course of hospital stay due to other coexisting morbidities.Conclusion: The management of pelvic injuries has always been a topic of debate, with multiple methods reported to date but growing evidence supports the use of pelvic arterial embolization in hemorrhagic pelvic injuries. The formulation of a standardized protocol is the need of the day.

Bleeding iliac artery pseudoaneurysm after colorectal anastomotic leak

Penetrating and blunt trauma, infection and dissection are all reported causes of abdominal pseudoaneurysms, which are usually managed by endovascular embolization. We report the first case in the literature of a pelvic pseudoaneurysm secondary to a colorectal anastomotic leak.

Trading scalpels for sheaths

The skill set of the acute care surgeon can be expanded by formal training. We report the first series of traumatic vascular injury (TVI) treated by acute care surgeons trained in endovascular techniques (ACSTEV). We retrospectively reviewed patients admitted to our trauma center with TVI over 5 months who survived for more than 24 hours and had catheter diagnosis and/or therapy by ACSTEV. Demographics, admission data, and outcomes were reviewed. Follow-up ranged from 0 day to 150 days. Most patients were male (63%) and sustained blunt mechanism (91%). Mean (SD) age was 48.2 (21.9) years, and mean (SD) Injury Severity Score was 32.1 (11.8). Mean (SD) admission systolic blood pressure, heart rate, Glasgow Coma Scale (GCS) score were 126.12 (30.4) mm Hg, 101.21 (28.2) beats per minute, and 10.8 (4.73), respectively. Forty-six patients underwent 48 endovascular procedures for TVI: 32 angiograms and 16 venograms were obtained. Two pelvic angiograms and one aortic arch angiogram were negative and required no treatment. One superficial femoral artery arteriogram showed minor luminal defects requiring anticoagulation only. Pseudoaneurysms were found in 17 vessels, vessel truncation in 4, active extravasation in 5, stenosis in 1, and dissection with thrombus in 1. Four patients had resuscitative endovascular balloon occlusion of the aorta performed before catheter intervention for pelvic hemorrhage. Procedures included aortic repair (4), pelvic embolization (13), splenic embolization (5), lumbar artery embolization (1), bronchial artery embolization (1), profunda artery embolization (1), common carotid artery stent (1), celiac artery stent (1), inferior vena cava filter placement (14) and retrieval (2), and pharmacomechanical thrombolysis (1). Treatment material included coils (12), Gelfoam (4), and nitinol plugs (3). No procedural or device-related complications occurred. Mortality was 14.7% unrelated to any endovascular procedure. One patient had repeat coil embolization of a pelvic pseudoaneurysm on postoperative Day 7. ACSTEV can safely treat TVI with good success. We performed nearly 10 procedures per month underscoring the role of the ACSTEV for training and care of TVI in a high-volume trauma center. Therapeutic study, level V.

Holmium Laser Enucleation of the Prostate and Iatrogenic Arteriovenous Fistula Treated by Superselective Arterial Embolization.

Iatrogenic pelvic pseudoaneurysm with concomitant arteriovenous fistula has been described as a rare and challenging complication, which may occur during transurethral resection of the prostate. We provide the first report of this complication after holmium laser enucleation of the prostate for the treatment of benign prostatic hyperplasia. The attempt to control the bleeding by conversion to open surgery and placement of haemostatic stitches into the prostatic fossa failed. Angiography with superselective arterial embolization proved to be a modern, quick, safe, and efficient treatment of this uncommon complication.

Postpartum Hemorrhage Resulting from Pelvic Pseudoaneurysm: A Retrospective Analysis of 588 Consecutive Cases Treated by Arterial Embolization

This study was designed to determine the incidence of arterial pseudoaneurysm in patients presenting with postpartum hemorrhage (PPH), to analyze the angiographic characteristics of pseudoaneurysms that cause PPH, and to evaluate the effectiveness of pelvic arterial embolization for the treatment of this condition. Eighteen women with pelvic arterial pseudoaneurysm were retrieved from a series of 588 consecutive patients with PPH treated by arterial embolization. Clinical files, angiographic examinations, and procedure details were reviewed. The incidence of pseudoaneurysm was 3.06 % (18/588; 95 % confidence interval (CI): 1.82-4.8 %). A total of 20 pseudoaneurysms were found; 15/20 (75 %) were located on the uterine arteries. Angiography revealed extravasation of contrast material from pseudoaneurysm indicating rupture in 9 of 18 (50 %) patients. Arterial embolization was performed using gelatin sponge alone in 12 of 18 (67 %) patients or in association with metallic coils in 5 of 18 (28 %) patients or n-butyl-2-cyanoacrylate in 1 of 18 (6 %) patients. Arterial embolization allowed controlling the bleeding in all patients after one or two embolization sessions in 17 of 18 (94 %) and 1 of 18 patients (6 %) respectively, without complications, obviating the need for further surgery. Pseudoaneurysm is rarely associated with PPH. Arterial embolization is an effective and safe procedure for the treatment of PPH due to uterine or vaginal artery pseudoaneurysm. Our results suggest that gelatin sponge is effective for the treatment of ruptured pseudoaneurysms, although we agree that our series does not contain sufficient material to allow drawing definitive conclusions with respect to the most effective embolic material.

Delayed Hypogastric Artery Pseudoaneurysm Following Blunt Trauma Without Evidence of Pelvic Fracture

Arterial pelvic bleeding caused by bony fragments is a common finding in patients with pelvic fractures after blunt trauma (Durkin et al., Am J Surg 2006;192:211-23). However, arterial injury in the absence of bony fracture is extremely rare, and in the event that it does occur, is immediately discovered on cross-sectional imaging. We present an unusual case of a 15-year-old boy who was involved in a bicycle accident, and who, a week after his injury, developed a delayed hypogastric branch artery pseudoaneurysm causing sciatic nerve compression with a right foot drop. Initial magnetic resonance imaging scan and pelvic X-ray at the time of the injury showed no evidence of pelvic fracture or vascular damage. The pseudoaneurysm was successfully treated with selective coil embolization and hematoma evacuation. This study represents only the second reported case of delayed pelvic pseudoaneurysm in the absence of pelvic fracture.

Pelvic pseudotumor and pseudoaneurysm in a pediatric patient with moderate hemophilia B: Successful management with arterial embolization and surgical excision

Development of pseudotumors is an unusual complication of hemophilia. Treatment is controversial, especially in patients with large proximal lesions. Surgery, while curative, can be associated with massive intra-operative bleeding, infection and amputation. Arterial embolization of blood vessels supplying the pseudotumor may reduce these complications. Herein, we report a 14-year-old patient with moderate hemophilia B with a pelvic pseudotumor and pseudoaneurysm that failed conservative management with factor replacement alone. He was successfully treated with Bead Block and coil embolization followed by surgical extirpation of the lesion 24 hr later.

Post-traumatic Pelvic Pseudoaneurysm and Arterio-venous Fistula: Combined Endovascular and Surgical Approach

Post-traumatic pelvic pseudoaneurysms are rare and challenging to manage. We describe the combined endovascular and surgical strategy used, to successfully treat a large internal iliac pelvic pseudoaneurysm combined with arterio-venous fistula, in a patient presenting 20 years following an elective caesarean section.

A pelvic pseudoaneurysm (a rare complication of oocyte retrieval for IVF) treated by arterial embolization

This is a case report of the diagnosis and treatment of a pelvic pseudoaneurysm in a patient. Her history leads to the conclusion that this developed following egg retrieval during in vitro fertilization six years earlier.
