Clinicopathological Evaluation of Postpancreaticoduonenectomy Hemorrhage with Endovascular Treatment.

Introduction: Postpancreaticoduodenectomy hemorrhage (PPH) is a serious complication. Fatty or nonfibrous pancreas, or both, is a risk factor for pancreatic fistula. This study assessed various prognostic factors for interventional procedures for PPH, also focusing on the degree of pancreatic fatty infiltration/fibrosis evaluated histopathologically.

The infrapatellar plica of the knee: analysis of relationship with femoral trochlear chondrosis using radiographs and 3.0-T MRI.

Objective: To assess the relationship of the infrapatellar plica (IPP) with femoral trochlear chondrosis (FTC) using radiographs and 3.0-T MRI.

Materials And Methods: Four hundred eighty-three knees of 476 patients undergoing radiography and MRI were reviewed, and 280 knees of 276 patients were included.

Ultraselective embolization using a 1.7-Fr catheter and soft bare coil for small intestinal bleeding.

Objective: We aimed to evaluate the safety and efficacy of embolization using a 1.7-Fr catheter and soft bare coil to treat acute small intestinal bleeding.

Material And Methods: Subjects were five consecutive patients who experienced onset of melena with small intestinal bleeding and underwent transcatheter arterial embolization with 1.

Endovascular Management of Intractable Postpartum Hemorrhage Caused by Vaginal Laceration.

Purpose: We evaluated the management of transcatheter arterial embolization for postpartum hemorrhage caused by vaginal laceration.

Materials And Methods: We reviewed seven cases of patients (mean age 30.9 years; range 27-35) with intractable hemorrhages and pelvic hematomas caused by vaginal lacerations, who underwent superselective transcatheter arterial embolization from January 2008 to July 2014.

Management of visceral artery embolization using 0.010-inch detachable microcoils.

Transcatheter coil embolization is used primarily to treat arterial hemorrhages, tumors, aneurysms, and vascular malformations. However, conventional microcatheter systems cannot always be employed in difficult cases. In this technical note, we describe how small-diameter primary coils and microcatheter tips that are thinner than normal can be used to increase the safety and reliability of coil embolization.

Follow-up of true visceral artery aneurysm after coil embolization by three-dimensional contrast-enhanced MR angiography.

Purpose: We aimed to evaluate the outcomes of coil embolization of true visceral artery aneurysms by three-dimensional contrast-enhanced magnetic resonance (MR) angiography.

Materials And Methods: We used three-dimensional contrast-enhanced MR angiography, which included source images, to evaluate 23 patients (mean age, 60 years; range, 28-83 years) with true visceral artery aneurysms (splenic, n=15; hepatic, n=2; gastroduodenal, n=2; celiac, n=2; pancreaticoduodenal, n=1; gastroepiploic, n=1) who underwent coil embolization. Angiographic aneurysmal occlusion was revealed in all cases.

A newly developed double lumen microballoon catheter with a side hole: initial experience of intraarterial infusion chemotherapy and/or embolization.

Purpose: To introduce a newly developed double lumen microballoon catheter with a side hole for intraarterial infusion chemotherapy and/or embolization.

Methods And Materials: Seven patients with malignant tumors, for whom superselective catheterization was considered difficult or had failed, underwent intraarterial infusion chemotherapy and/or embolization with the 3.3-Fr microballoon catheter.

Hepatic arterial infusion chemotherapy with a coaxial reservoir system using a non-braided spiral tip microcatheter.

Purpose: To evaluate the efficacy and safety of a coaxial reservoir system with a non-braided spiral tip microcatheter and exclusive port for hepatic arterial infusion chemotherapy.

Materials And Methods: In vitro evaluation included evaluation of pressure tolerance/flow rate of the coaxial reservoir system, and the strength of connection between the 2.7-F catheter and port.

Bronchioloalveolar carcinoma with fluctuating extent of consolidation on chest radiography.

We report a case of bronchioloalveolar carcinoma that required approximately 1 year to diagnose due to alternating periods of exacerbation and improvement of abnormal opacity on chest radiography. It is important to consider the diagnosis of bronchioloalveolar carcinoma when consolidative opacities simulating pneumonia show an alternating pattern of worsening and improvement.
