Vascular Resections in Association With Pancreatic Resections for Locally Advanced Pancreatic Cancer.

Background/aim: Locally advanced pancreatic cancer has been considered for a long period of time as an unresectable lesion and therefore, all patients have been traditionally addressed to the oncological services for palliative purposes. However, due to the wide usage of newer oncological agents in association with improved surgical techniques, radical surgical procedures became feasible. The aim of this study was to present the different surgical procedures that were performed in locally advanced pancreatic cancer patients in order to achieve radical resections.

Major Hepatectomy En Bloc with Cava Vein Resection for Locally Invasive Caudate Lobe Hepatocarcinoma.

Background/aim: Locally advanced liver tumours with vascular invasion have been considered for a long period of time as unresectable lesions, so the patient was further deferred to oncology services for palliation. However, improvement of the surgical techniques and the results reported so far came to demonstrate that extended hepatic and vascular resections might be safely performed in such cases and might significantly improve the long-term outcomes.

Materials And Methods: A 61-year-old patient was diagnosed with a caudate lobe tumour invading the inferior cava vein and the right hepatic pedicle.

Infra-hepatic caval resection en bloc with right nephrectomy followed by caval reconstruction for locally advanced caval leiomyosarcoma: A case report and literature review.

Retroperitoneal sarcomas often require complex surgical procedures in order to achieve complete resection; in such cases both vascular and visceral resections are needed. When it comes to the need for vascular reconstruction, the type of graft as well as the type of reconstructive process are chosen according to the length and location of the resected segment. Meanwhile, depending on the location of the resected segment, other vascular reconstructions may be needed such as the reimplantation of the renal veins.

Pancreatectomy With Arterial and Portal Vein Reconstruction for Locally Advanced Pancreatic Cancer - A Case Report and Literature Review.

Background/aim: Pancreatic cancer is still associated with poor survival rates due to the fact that it is most often diagnosed at advanced stages of the disease when local invasion is present. However, improvements of surgical techniques have enabled extended resections with curative intent. We present the case of a 43-year-old patient diagnosed with locally invasive pancreatic adenocarcinoma invading the portal vein and the common hepatic artery.

Distal Pancreatectomy With Splenectomy, Celiac Axis and Portal Vein Resection Followed by Arterial Reconstruction Using a Cadaveric Graft - A Case Report and Literature Review.

Background/aim: Locally advanced pancreatic body tumors invading the celiac axis and the portal vein have been considered since long as unresectable lesions; however, due to improvement of surgical techniques, in certain cases surgery with curative intent might be taken in consideration.

Case Report: We present the case of a 48-year-old female investigated for epigastric pain that was diagnosed with a locally invasive pancreatic body tumor. The patient was submitted to computed tomography which revealed the presence of a locally advanced pancreatic tumor with no demarcation line with the celiac axis and the portal vein.

Management of a Fulminant Upper Gastrointestinal Bleeding Exteriorized Through Hemobilia Due to Arteriobiliary Fistula Between the Common Bile Duct and a Right Hepatic Artery Aneurysm - A Case Report.

Right hepatic artery aneurysms are rare events that might remain asymptomatic for a long period of time. However, in cases presenting large lesions, symptoms might develop especially due to the association of compression of the surrounding elements. Most often these symptoms and signs include diffuse abdominal pain, jaundice or portal vein compression signs.

Successful Resection and Vascular Ligation of a Large Hepatic Artery Aneurysm - A Case Report and Literature Review.

The occurrence of hepatic artery aneurysms is rare and might be incidentally diagnosed, as the patient remains asymptomatic for a long period of time. However, due to the fact that these lesions are associated with a high risk of developing life threatening complications, such as intraperitoneal rupture, it has been stated that all cases should be submitted to treatment by endovascular or surgical approach. We present the case of a 68-year-old patient, who presented with recurrent upper digestive tract bleedings and was diagnosed with a large aneurysm of the common and the proper hepatic artery, and the gastroduodenal artery.

Ante-situm Liver Resection for Giant Hepatic Tumour - Case Report and Review of Literature.

Ex-situ liver surgery refers to complex liver resections involving hepatic vascular exclusion and a warm ischemia time (WIT) of more than 90 minutes that allows liver resection and vascular reconstruction in patients with giant liver tumours with a difficult approach . Ante-situm liver resections, otherwise called "œex-situ in-vivo" resections is achieved through externalization of the liver outside of the abdominal cavity by clamping and sectioning of the efferent pedicles (suprahepatic veins) ("ex situ") without cutting the afferent vascular pedicle ("in vivo"), thus leaving the hepatic pedicle intact. We present a case report of a 36 yo male patient diagnosed by MRI scan with giant liver tumor in the left hemiliver.

Pancreatoduodenectomy en bloc with portal and superior mesenteric artery resection--a case report and literature review.

Background: Pancreatic cancer is one of the most lethal malignancies and is associated with a very poor overall survival. However, it seems that the only curative option remains an aggressive surgical approach capable of obtaining a radical resection. Unfortunately, this desiderate is even harder to be obtained when it comes to pancreatic tumors with vascular invasion.

Status of the Southern Carpathian forests in the long-term ecological research network.

Air pollution, bulk precipitation, throughfall, soil condition, foliar nutrients, as well as forest health and growth were studied in 2006-2009 in a long-term ecological research (LTER) network in the Bucegi Mountains, Romania. Ozone (O(3)) was high indicating a potential for phytotoxicity. Ammonia (NH(3)) concentrations rose to levels that could contribute to deposition of nutritional nitrogen (N) and could affect biodiversity changes.

New international long-term ecological research on air pollution effects on the Carpathian Mountain forests, Central Europe.

An international cooperative project on distribution of ozone in the Carpathian Mountains, Central Europe was conducted from 1997 to 1999. Results of that project indicated that in large parts of the Carpathian Mountains, concentrations of ozone were elevated and potentially phytotoxic to forest vegetation. That study led to the establishment of new long-term studies on ecological changes in forests and other ecosystems caused by air pollution in the Retezat Mountains, Southern Carpathians, Romania and in the Tatra Mountains, Western Carpathians on the Polish-Slovak border.
