Ablation in Pancreatic Cancer: Past, Present and Future.

The insidious onset and aggressive nature of pancreatic cancer contributes to the poor treatment response and high mortality of this devastating disease. While surgery, chemotherapy and radiation have contributed to improvements in overall survival, roughly 90% of those afflicted by this disease will die within 5 years of diagnosis. The developed ablative locoregional treatment modalities have demonstrated promise in terms of overall survival and quality of life.

Ultrasound-Assisted Catheter-Directed Thrombolysis for Submassive Pulmonary Embolism.

Purpose: Catheter-directed thrombolysis (CDT) is a relatively new therapy for pulmonary embolism that achieves the superior clot resolution compared to systemic thrombolysis while avoiding the high bleeding risk intrinsically associated with that therapy. In order to examine the efficacy and safety of CDT, we conducted a retrospective cohort study of patients undergoing ultrasound-assisted CDT at our institution.

Methods: The charts of 30 consecutive patients who underwent CDT as a treatment of pulmonary embolism at our institution were reviewed.

Late endovascular removal of Günther-Tulip inferior vena cava filter and stent reconstruction of chronic post-thrombotic iliocaval obstruction after 4753 days of filter dwell time: a case report with review of literature.

Chronic post-thrombotic obstruction of the inferior vena cava (IVC) or iliocaval junction is an uncommon complication of long indwelling IVC filter. When such an obstruction is symptomatic, endovascular treatment options include stent placement with or without filter retrieval. Filter retrieval becomes increasingly difficult with longer dwell times.

Transsplenic portal vein reconstruction-transjugular intrahepatic portosystemic shunt in a patient with portal and splenic vein thrombosis.

Portal vein thrombosis (PVT) is a potential complication of cirrhosis and can worsen outcomes after liver transplant (LT). Portal vein reconstruction-transjugular intrahepatic portosystemic shunt (PVR-TIPS) can restore flow through the portal vein (PV) and facilitate LT by avoiding complex vascular conduits. We present a case of transsplenic PVR-TIPS in the setting of complete PVT and splenic vein (SV) thrombosis.

Acute tumor lysis syndrome after proximal splenic artery embolization.

Preoperative splenic artery embolization for massive splenomegaly has been shown to reduce intraoperative hemorrhage during splenectomy. We describe a case of tumor lysis syndrome after proximal splenic artery embolization in a patient with advanced mantle cell lymphoma and splenic involvement. The patient presented initially with hyperkalemia two days after embolization that worsened during splenectomy.

Irreversible Electroporation (IRE) in Renal Tumors.

Small renal masses (SRMs) have been traditionally managed with surgical resection. Minimally invasive nephron-sparing treatment methods are preferred to avoid harmful consequences of renal insufficiency, with partial nephrectomy (PN) considered the gold standard. With increase in the incidence of the SRMs and evolution of ablative technologies, percutaneous ablation is now considered a viable treatment alternative to surgical resection with comparable oncologic outcomes and better nephron-sparing property.

Proximal Splenic Artery Embolization in Chemotherapy-Induced Thrombocytopenia: A Retrospective Analysis of 13 Patients.

Purpose: To determine if proximal splenic artery embolization (PSAE) provides a safe and effective alternative to alleviate chemotherapy-induced thrombocytopenia (CIT), allowing patients with cancer to resume chemotherapy regimens.

Materials And Methods: Thirteen patients (9 men, 4 women; mean age, 63 y) with underlying malignancy (pancreatic adenocarcinoma, n = 6; cholangiocarcinoma, n = 5; other, n = 2) complicated by CIT underwent PSAE. Mean platelet counts were calculated before the initiation of chemotherapy, at the nadir that resulted in discontinuation of chemotherapy before the PSAE procedure, at peak values after the procedure, and at a mean follow-up of 9.
