Gastrointestinal bleeding from small-bowel varices is a rare and difficult to treat complication of portal hypertension. We describe the case of a 79-year-old female patient with recurrent severe hemorrhage from small-bowel varices 30 years after a complicated cholecystectomy. When double balloon enteroscopy was unsuccessful to reach the site of ...

Angiography has become an integral tool in the management of patients with gastrointestinal bleeding. It is used for localizing the site of bleeding and then for controlling the bleeding when more conservative methods of treatment are unsuccessful.

Localizing active sites of bleeding within the small intestine remains a difficult task. Endoscopic, angiographic or scintigraphic studies may point to the small intestine as the site of blood loss, but at operation, without a palpable lesion, the exact site of bleeding remains elusive. ...

Trocars used in laparoscopic surgery occasionally produce serious complications, such as bleeding, visceral injury, or incisional hernia. We report the evaluation of a new, potentially safer laparoscopic access device in which the cutting obturator of a standard trocar is replaced by a blunt, radially expanding device. Conventional and radially expanding ...

A patient is described who had coagulopathy and clinically intermittent gastrointestinal bleeding. The bleeding site was clearly shown on renal and bone imaging performed at a time when the patient was considered clinically to have stopped bleeding. A bleeding gastric ulcer was subsequently ...

For over one decade Glycoproteins IIb/IIIa inhibitors (GPI) have been administered to prevent coronary artery thrombosis. Initially these agents were used for acute coronary syndromes and subsequently as adjunctive pharmacotherapy for percutaneous coronary interventions (PCIs). Most benefit of GPI emerged from reduction of ischemic events: mostly non-q-wave myocardial infarctions (NQWMIs) during ...

A pelvic radionuclide angiogram (PRAG) was obtained in addition to Tc-99m-labeled red blood cell scans in 18 studies (16 patients) of gastrointestinal bleeding.

Brachial artery access is a good alternative for performing percutaneous transluminal angioplasty when femoral access is contraindicated or not feasible. Although several closure devices are available for femoral access, haemostasis for brachial artery access is still achieved by manual compression with several ...

Temporary hemodialysis is conventionally performed by accessing either the jugular, the femoral, or the subclavian veins. Repetitive or chronic use of these venous sites may lead to complications such as thrombosis of the superior vena cava. Alternative venous accesses have been described. The purpose of this acute experiment is to ...

Massive rectal bleeding from the appendix, considered a rare case of lower gastrointestinal bleeding, is not easily recognized by various diagnostic modalities.

BACKGROUND:Treatment of symptomatic coronary artery disease with percutaneous intervention requires antithrombotic therapy. Patients with elevated thromboembolic risk benefit from therapy with glycoprotein IIb/IIIa inhibitors. The safety and effectiveness of glycoprotein IIb/IIIa inhibition have been well documented in clinical trials. Drug-induced bleeding complications in ...

BACKGROUND: Complications at the vascular access sites are among the most common adverse events in congenital cardiac catheterization. The use of small-gauge catheters may reduce these events; however, other factors can contribute to the development of vascular complications. OBJECTIVES: To determine factors associated with the development of vascular ...

Upper gastrointestinal bleeding is a life threatening condition in children. Common sources of upper gastrointestinal bleeding in children include variceal hemorrhage (most commonly extra-hepatic portal venous obstruction in our settings) and mucosal lesions (gastric erosions and ulcers secondary to drug intake). While most gastrointestinal ...

A cross-sectional survey of haemophilia B carriers included a multiple ...

OBJECTIVE: Primary percutaneous coronary intervention (PPCI) has been acknowledged by the most recent European guidelines to be the preferred treatment for ST elevation myocardial infarction (STEMI). Patients undergoing PPCI are expected to receive a broad spectrum of anticoagulants and antiplatelet agents, which increases the risk of bleedings, in most cases, at the ...

Before ten years, radial artery was discovered as a useful vascular access site for percutaneous coronary procedures. It has the advantage of reduced access site complications but is associated with specific technical challenges in comparison with the transfemoral approach. Although earlier data from a ...

We report what is believed to be the first case of life-threatening rectal bleeding following this procedure, which was successfully treated by endoscopic intervention through placement ...

The experience with 62 /sub 99m/Tc-labeled in vivo scans performed for lower gastrointestinal bleeding is discussed. Thirty-seven scans were deemed positive. The tendency of scans to become positive correlated with observations of active bleeding. Five patients had fulminant hemorrhage, necessitating emergency operation. In this group, scanning accurately ...

Iatrogenic injuries to blood vessels in joint replacement surgery are rare events that occur as few per thousand. Howe- ver, their sequelae are serious. The patient may either bleed to death, because vascular injury is not obvious and therefo- re difficult to diagnose, or lose the limb due to ischaemia. The highest risk of vascular injury is associated with repeat sur- gery ...

Abdominal wall bleeding may complicate any laparoscopic procedure. Piercing or laceration of vessels transversing the abdominal wall during trocar placement is generally the cause. Bleeding may occur at the very beginning of the surgery but, in some cases, it may go unrecognized for a while complicating the operation and the postoperative course. Planned ...

The spectrum of dengue infection varies from dengue fever to more severe forms such as dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). In DHF bleeding may be overt (external) or internal. At time bleeding can occur at unusual sites. We report one such case of DHF in which bleeding occurred within ...

A case of gastrointestinal bleeding in a 73-year-old man secondary to vascular ectasia is presented. The use of the 99m technetium-tagged erythrocyte scanning to localize the bleeding site and arteriography to document a vascular malformation strongly suggested this diagnosis.

Metastasis from lung cancer, often found in the adrenal glands, bone, liver, brain, and kidneys, have been thought to be rare in the digestive system. When a metastatic tumor is found in the intestine, it is most commonly metastatic melanoma or carcinoma of the cervix uteri, ovary, or breast. Yet, intestinal metastases have been described in 11% of lung cancers at autopsy. These metastases may ...

Introduction:Acute coronary syndromes and non-Q-wave myocardial infarction are often initiated by platelet activation. Eptifibatide is a cyclic heptapeptide and is the third inhibitor of glycoprotein (Gp) IIb/IIIa that has found broad acceptance after the specific antibody abciximab and the nonpeptide tirofiban entered the global market. Gp IIb/IIIa inhibitors act by inhibiting the final common ...

Little has been written about acute blood loss from hemodialysis vascular access.
