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.

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.

Ultraselective arterial embolization of vasa recta using 1.7-French microcatheter with small-sized detachable coils in acute colonic hemorrhage after failed endoscopic treatment.

Objective: The purpose of this article is to document our experiences with ultraselective arterial embolization to manage acute colonic hemorrhage using a 1.7-French microcatheter with small-sized detachable coils and to discuss the feasibility and clinical efficacy of this new technique.

Conclusion: We achieved technical success in all four patients with the sole use of short-segment embolization of the long branch of the vasa recta.

Bell-shaped sensory impairments of all modalities in a neurosarcoidosis patient.

We describe a 45-year-old man with neurosarcoidosis complaining of bell-shaped tightening and pain with sensory disturbance of superficial and deep sensations. The patient showed subacute progressive sensory impairment in bilateral C7-Th12 dermatomes. Triceps and patellar tendon reflexes were decreased.
