We report the case of a 48-year-old man with neurofibromatosis presenting with sudden-onset abdominal pain, profound hypotension, and a drop in hemoglobin. CT scan demonstrated a massive hematoma within the right lobe of the liver with rupture into the peritoneal cavity. Angiography demonstrated diffuse abnormalities of the hepatic circulation with fusifom, ectatic, and stenotic segments. Acute extravasation from a peripheral branch of the right hepatic artery was identified and successfully embolized with subsequent hemodynamic stabilization of the patient. To the best of our knowledge this is the first case report of this kind in a patient with type I neurofibromatosis.

Fine needles with an end hole or multiple side holes have traditionally been used for percutaneous ethanol injection (PEI) of hepatomas. This study retrospectively evaluates the safety and efficacy of PEI of unresectable medium-to-large (3.5-9 cm) hepatomas using a multipronged needle and with conscious sedation. Twelve patients, eight men and four women (age 51-77 years; mean: 69) received PEI for hepatomas, mostly subcapsular or exophytic in location with average tumor size of 5.6 cm (range: 3.5-9.0 cm). Patients were consciously sedated and an 18G retractable multipronged needle (Quadrafuse needle; Rex Medical, Philadelphia, PA) was used for injection under real-time ultrasound guidance. By varying the length of the prongs and rotating the needle, the alcohol was widely distributed within the tumor. The progress of ablation was monitored by contrast-enhanced ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) after each weekly injection and within a month after the final (third) injection and 3 months thereafter. An average total of 63 mL (range: 20-154 ml) of alcohol was injected per patient in an average of 2.3 sessions. Contrast-enhanced CT, ultrasound, or MRI was used to determine the degree of necrosis. Complete necrosis was noted in eight patients (67%), near-complete necrosis (90-99%) in two (16.7%), and partial success (50-89%) in two (16.7%). Follow-up in the first 9 months showed local recurrence in two patients and new lesions in another. There was no mortality. One patient developed renal failure, liver failure, and localized perforation of the stomach. He responded to medical treatment and surgery was not required for the perforation. One patient had severe postprocedural abdominal pain and fever, and another had transient hyperbilirubinemia; both recovered with conservative treatment. PEI with a multipronged needle is a new, safe, and efficacious method in treating medium-to-large-sized hepatocellular carcinoma under conscious sedation. Its survival benefits require further investigations.

An aorto-caval fistula is a rare complication of a symptomatic or ruptured infrarenal aortic aneurysm having a frequency of 3-6%. Patients typically present with clinical signs of diffuse abdominal pain associated with increasing venous congestion and tachycardia, rapid cardiopulmonary decompensation with acute dyspnea, and an audible machinerylike bruit. Perioperative mortality is high, ranging from 20% to 60%. We report a case of an endovascular aortic repair in a patient with a symptomatic infrarenal aortic aneurysm and an aorto-caval fistula. Contrast-enhanced ultrasound seems to be a promising new diagnostic option for the diagnosis and preoperative treatment planning for patients with abdominal aortic aneurysms with rupture into the inferior vena cava. It is in addition to computed tomography angiography. It might allow a more rapid and noninvasive diagnosis, especially for patients in intensive care because of its bedside availability. Because the examination is dynamic, additional information about blood flow between the aorta and inferior cava vein can be evaluated.

We present a complex case of a splanchnic arterioportal vein fistula in a patient who presented with weight loss, abdominal pain, diarrhea, and pancreatitis. We report successful use of the Guglielmi Detachable Coil (GDC) and N-butyl cyanoacrylate glue for the therapeutic embolization of the fistula between the superior mesenteric artery, the common hepatic artery, and the portal vein. On the day following the procedure, the patient reported total remission of the abdominal pain and diarrhea. These results were maintained at 3 months follow-up.

Although cardiovascular mortality for men has been declining, the number of women dying from cardiovascular disease has slightly increased. Differences between women and men have been identified throughout the entire spectrum of ischemic heart disease, from risk factors to presentation and from diagnosis to treatment and outcomes. In the setting of an acute coronary syndrome or acute myocardial infarction, women are significantly more likely than men to report multiple non-chest pain symptoms, including dyspnea, nausea/vomiting, abdominal pain, back pain, neck pain, and jaw pain. Investigations into the pathophysiology of ischemic heart disease in women have broken away from the traditional thinking that coronary artery disease simply equals epicardial stenosis. In women, the new paradigm of coronary artery disease also focuses on diffuse atherosclerosis, endothelial dysfunction, and microvascular disease. Further research focusing on sex differences in cardiovascular disease is needed, but enough is currently known to offer a sex-based approach, which may ultimately lead to improved outcomes.

An aorto-caval fistula caused by a ruptured false aneurysm of the abdominal aorta was reported. A 70-year-old male who had a history of aorto-femoral bypass was admitted because of right lower abdominal pain. Enhanced computed tomography scans revealed aorto-caval fistula. The patient exhibited high output heart failure and acute renal failure. Stent-grafting for abdominal aorta was performed. Intra- and postoperative examination revealed no leakage from the aorta to the vena cava. Endoluminal treatment for aorto-caval fistula is efficacious as less invasive treatment.

A patient was admitted because of severe abdominal pain, anorexia, and intestinal bleeding. Contrast-enhanced multidetector computed tomography demonstrated acute portal and superior mesenteric vein thrombosis (PSMVT). The patient was treated percutaneously with transjugular intrahepatic portosystemic shunt (TIPS), mechanical aspiration thrombectomy, and direct thrombolysis, and 1 week after the procedure, complete patency of the portal and superior mesenteric veins was demonstrated. TIPS, mechanical aspiration thrombectomy, and direct thrombolysis together are promising endovascular techniques for the treatment of symptomatic acute PSMVT.

We report the case of a 39-year-old woman who developed worsening dyspnea and abdominal pain 4 days after subtotal gastroresection. She underwent thoracic computed tomography scan and lung scintigraphy and was diagnosed with pulmonary embolism. Despite the fact that she was feverish, she was treated by the insertion of a vena cava filter and transferred to our Emergency Department. Twelve hours later, a beta-haemolytic Streptococcus agalactiae was reported to be growing in both bottles of blood cultures that had been taken. The patient underwent transthoracic two- and three-dimensional echocardiography, which showed a large pulmonary valve vegetation prolapsing into the main and right pulmonary artery during systole.

A 30-year-old man with severe back and abdominal pain was referred to our hospital because of a recurrence of acute type B aortic dissection. A computed tomography scan showed a 3-channel dissection and a severe narrowing of the true lumen of the descending aorta to the abdominal aorta because of the expansion of the newly formed second false lumen. Although laboratory testing, including creatine phosphokinase, lactate dehydrogenase, and lactate levels, indicated no visceral ischemia, abdominal pain requiring narcotics treatment had to be continued for more than 1 week. Based on the symptoms and computed tomography findings, the patient finally underwent aortic replacement, fenestration, and a reconstruction of the inferior mesenteric artery, after which the abdominal pain disappeared. Operative findings confirmed a pale shrunken intestine, indicative of mesenteric ischemia. The present case is a good demonstration revealing that mesenteric ischemia still remains a diagnostic challenge, and suggests that currently available laboratory markers are not sensitive enough to detect the presence of ischemia. A strong clinical suspicion for mesenteric ischemia may be the only key to preventing a catastrophic outcome in this condition.

Portal vein thrombosis is a rare but well-known complication after abdominal surgery. To our knowledge, there have been no reports about this complication after cardiopulmonary bypass surgery. This can probably be explained by the variety of clinical pictures and difficulties in the establishment of a diagnosis of portal vein thrombosis. Among the possible trigger factors, bacteremia, that is usually caused by Bacteroides fragilis or by Escherichia coli, has been assessed. In this case, several blood culture specimens and fluid from abdominal paracentesis consistently grew coagulase-negative staphylococci which have been proved to be one of the most common pathogens in postoperative infection after cardiac surgery. The patient received clopidogrel before and after coronary artery bypass grafting. We speculate that in this clinical situation associated with coagulase-negative staphylococcal bacteremia, clopidogrel resistance may play an important role. The natural history of portal vein thrombosis in this case is complicated by massive fatal gastrointestinal bleeding from rupture of the esophageal varices. Emergency endoscopic therapy with esophageal variceal ligation, injection of a sclerosing solution and using of vasoconstrictive agents helped only in the first episode of bleeding. Portal vein thrombosis after coronary artery bypass grafting is a serious complication. The clinical picture of portal vein thrombosis may vary greatly and the presence of this condition should be suspected when faced with abdominal pain with gastrointestinal bleeding of unknown origin and sepsis.
