Side branch embolization before endovascular abdominal aortic aneurysm repair to prevent type II endoleak: A prospective multicenter study.

Purpose: The purpose of the study was to evaluate the efficacy and safety of pre-emptive transcatheter arterial embolization (P-TAE) of aortic side branches to prevent type II endoleak in patients with abdominal aortic aneurysm after endovascular abdominal aneurysm repair (EVAR).

Materials And Methods: This multicenter, prospective, single-arm trial enrolled 100 patients with abdominal aortic aneurysm from nine hospitals between 2018 and 2021. There were 85 men and 15 women, with a mean age of 79.

Retrospective study of thoracic endovascular aortic repair as a first-line treatment for traumatic blunt thoracic aortic injury.

Objective: This study sought to confirm if thoracic endovascular aortic repair (TEVAR) was an appropriate therapeutic strategy for blunt thoracic aortic injury (BTAI).

Methods: Between 3/2005 and 12/2020, 104 patients with BTAI were brought to our hospital. The severity of each trauma case was evaluated using the Injury Severity Score (ISS); aortic injuries were classified as type I to IV according to Society for Vascular Surgery guidelines.

[Pelvic arteriovenous malformation : a case report].

A 70-year-old male presented with intermittent macroscopic hematuria. There was no history of previous trauma or pelvic operation. At first, we were unable to clarify the origin of the hematuria, but 3D computed tomography revealed an arteriovenous malformation (AVM) consisting of multiple feeding vessels arising from the bilateral, especially right, internal iliac artery.

Endovascular uncovered Wallstent placement for life-threatening isolated iliac vein injury caused by blunt pelvic trauma.

Isolated iliac vein injury caused by blunt pelvic trauma is a rare condition that is difficult to diagnose and often fatal. We report a case of a 52-year-old female who presented with life-threatening isolated iliac vein injury caused by blunt pelvic trauma that was successfully managed with endovascular uncovered stent placement. Although further studies are warranted to clarify the hemostatic mechanism, uncovered stent placement can be considered as an alternative treatment option to covered stent placement for life-threatening iliac vein injury when a covered stent is not rapidly available.

Curved nitinol stent-graft placement for treating blunt thoracic aortic injury: an early experience.

Background: Blunt trauma-induced aortic injury traditionally has been treated with early open surgical repair. However, recently endovascular stent-graft technology is considered a less-invasive therapeutic alternative, and flexible stent-grafts, such as the Matsui-Kitamura stent-graft (MKSG), are being used widely. We report our experience with the curved MKSG in treating thoracic aortic injuries.

Ruptured hepatic abscess caused by fish bone penetration of the duodenal wall: report of a case.

The accidental ingestion of a foreign body into the gastrointestinal tract is not uncommon; however, the development of a hepatic abscess secondary to foreign body perforation is extremely rare. We report the case of a ruptured hepatic abscess caused by fish bone penetration of the duodenal bulb, resulting in generalized peritonitis. A 73-year-old man was admitted to our hospital with generalized abdominal pain and high fever.

Three-dimensional images of contrast-enhanced MDCT for preoperative assessment of musculoskeletal masses: comparison with MRI and plain radiographs.

Purpose: To evaluate the diagnostic capability of contrast-enhanced multidetector computed tomography (MDCT) for the preoperative assessment of musculoskeletal masses, in comparison with magnetic resonance imaging and plain radiographs (MRI+X-p).

Materials And Methods: Sixty-eight patients with musculoskeletal masses underwent plain radiography, MRI, and contrast-enhanced MDCT. The following five items were evaluated for all images: histological properties, vascularity, neurovascular involvement, calcification/ossification, and cortical/marrow involvement.

Use of the wallstent for symptomatic relief of malignant inferior vena cava obstructions.

Purpose: To report our experience with the Wallstent for the relief of congestive symptoms in patients with malignant inferior vena cava (IVC) obstructions.

Materials And Methods: We treated five patients with malignant obstructions of the IVC with a total of seven self-expandable stents. All obstructions were due to extrinsic compression; the procedures were indicated to relieve congestive symptoms in patients unresponsive to other therapies or in whom other treatments were contraindicated.

Transcatheter embolization of splenic artery pseudo-aneurysm rupturing into colon after post-operative pancreatitis.

Splenic pseudoaneurysms following chronic pancreatitis can rarely become a source of life-threatening bleeding by rupturing into various regions or components, including pseudocysts, the abdominal cavity, the gastrointestinal tract, and the pancreatic duct. In such cases, prompt diagnosis and therapy are warranted. We report herein the case of a 52-year-old man in whom a splenic pseudoaneurysm ruptured into the colon via a fistula with an abscess cavity, causing massive bleeding, which was successfully managed by trans-catheter arterial embolization (TAE).

Renal arteriovenous fistula with rapid blood flow successfully treated by transcatheter arterial embolization: application of interlocking detachable coil as coil anchor.

A 70-year-old woman presented to our outpatient clinic with a large idiopathic renal arteriovenous fistula (AVF). Transcatheter arterial embolization (TAE) using interlocking detachable coils (IDC) as an anchor was planned. However, because of markedly rapid blood flow and excessive coil flexibility, detaching an IDC carried a high risk of migration.

Prophylactic stenting of the inferior vena cava before transcatheter embolization of renal cell carcinomas: an alternative to filter placement.

Purpose: To report the use of the self-expanding Wallstent as an alternative to prophylactic inferior vena cava (IVC) filter placement before embolization of renal carcinomas with tumor thrombus.

Case Reports: Two patients, a 71-year-old man and an 88-year-old woman, were diagnosed with extensive tumor infiltration of the IVC secondary to renal cell carcinomas. Prophylactic placement of an IVC filter before transcatheter embolization was unsuccessful in both cases; a reduced space for deployment would have left part of the filter inside the right atrium.
