Gastric arterio-venous malformation emerging from splenic artery
In this case report, we present a patient who suffered from gastrointestinal bleeding. The bleeding source was a gastric arterio-venous malformation emerging from the splenic artery. Attempts to stop the bleeding failed and therapeutic angiography succeeded in occluding the vessel. A search at the literature has not yielded any other case report describing this anatomical anomaly
Hemobilia due to hepatic artery aneurysm as the presenting sign of fibro-muscular dysplasia
Fibro-muscular dysplasia (FMD) is a rare but well documented disease with multiple arterial aneurysms. The patients, usually women, present with various clinical manifestations according to the specific arteries that are affected. Typical findings are aneurysmatic dilatations of medium-sized arteries. The renal and the internal carotid arteries are most frequently affected, but other anatomical sites might be affected too. The typical angiographic picture is that of a "string of beads". Common histological features are additionally described. Here we present a case of a 47-year-old woman, who was hospitalized due to intractable abdominal pain. A routine work-up revealed a liver mass near the portal vein. Before a definite diagnosis was reached, the patient developed massive upper gastrointestinal bleeding. In order to control the hemorrhage, celiac angiography was performed revealing features of FMD in several arteries, including large aneurysms of the hepatic artery. Active bleeding from one of these aneurysms into the biliary tree indicated selective embolization of the hepatic artery. The immediate results were satisfactory, and the 5 years follow-up revealed absence of any clinical symptoms

Vascular Access via Peripherally Inserted Central Venous Catheters (PICCs): Experience in 40 Patients with Acute Myeloid Leukemia at a Single Institute
Reliable long-term vascular access is essential for the treatment of patients with acute myeloid leukemia (AML). Although peripherally inserted central catheters (PICCs) have been in use for many years, little data exist on their use in patients receiving intensive chemotherapy. We retrospectively reviewed all AML patients who had a PICC inserted between July 95 and May 98. Fifty two PICCs were inserted in 40 patients with AML. Thirty three PICCs were inserted during severe thrombocytopenia (platelets < 50 × 109/L), and 31 during severe neutropenia (neutrophils < 0.5 × 109/L). Mean catheter duration was 82 (median 63, range 3-441) days fora total of 4274 catheter days. A mean of 1.8 chemotherapy courses were administered via each PICC. There were 5 early complications of PICC placement. Other mechanical complications occurred in 14 catheters and phlebitis in 12. Twenty blood stream infections (BSI) occurred in 17 patients. All BSIs occurred during neutropenia. Seventeen PICCs were removed due to the following complications - phlebitis (11), possible catheter related BSI (4), mechanical reasons in 3 (2 with concomitant phlebitis) and persistent fever (1). PICC duration was significantly shorter in these 17 catheters (52.9 v 96.4 days in the other 35, p=0.0289). We conclude that PICCs provide long-term vascular access with an acceptable complication rate in patients with AML. However, a randomised trial is required before PICCs can be considered an alternative to tunneled central venous catheters in these patients
