Lymphorrhea is a rare but potentially severe complication that occurs after various surgical procedures. Untreated lymphorrhea may lead to wound dehiscence, infection, and prolonged hospital stay. Currently, there no standard effective treatment. Early management usually includes leg elevation, drainage, pressure dressing. However, these methods are associated with recovery high recurrence rates. We report case of from calf endoscopic great saphenous vein (GSV) harvesting for coronary artery...
Afferent loop syndrome (ALS) is a rare complication of gastrectomies and gastrointestinal reconstruction. This can predispose patients to fatal conditions, such as cholangitis, pancreatitis, duodenal perforation with peritonitis. Therefore, emergency decompression necessary prevent these complications. Herein, we report two cases in which transcholecystic drainage, an alternative treatment, was performed ALS without bile duct dilatation. Two who underwent distal gastrectomy Billroth II...
Esophagojejunal varices occurring after total gastrectomy are rare but potentially fatal in cases of variceal bleeding. Owing to their rarity, treatment strategies for this condition not well established. Here, we describe the case a 48-year-old woman who presented with hematemesis and melena. Four years prior, she underwent gastric cancer. bleeding supplied by dilated jejunal vein, along liver cirrhosis, was diagnosed as per endoscopy computed tomography findings. Initial attempts at...
To evaluate the efficacy and safety of Amplatzer Vascular Plug 4 (AVP4) embolization in pulmonary arteriovenous malformations (PAVMs) with small- to medium-sized feeding arteries (<6 mm) identify factors affecting persistence main patterns after embolization.
Cardiac hemangiomas account for only 2.8% of primary cardiac tumors and are caused by the abnormal proliferation endothelial cells excess blood vessels. Typical radiological findings hemangioma demonstrate intense contrast enhancement.Here we report case a 69-year-old man who presented with right atrial mass found incidentally multimodal imaging findings, including echocardiography, computed tomography (CT), magnetic resonance (MRI). This poor enhancement within on dynamic contrast-enhanced...
Low-grade myofibroblastic sarcoma (LGMFS) is a rare type of sarcoma, and its manifestation as radiotherapy (RT)-induced following RT for breast cancer even more unusual. To date, only one case RT-induced mammary (MFS) has been reported. Here we present the 49-year-old woman with LGMFS after undergoing breast-conserving surgery invasive ductal carcinoma (IDC), history 16 years prior. Due to rarity this disease, previous studies have focused primarily on pathological findings MFS. In report...
The efficacy of bronchial artery embolization (BAE) for Dieulafoy's disease (BDD) has not been well established.This study aimed to evaluate the safety and BAE in patients with clinically suspected BDD presenting major hemoptysis, describe angiographic findings.17 (all men; mean age, 53.5 years) diagnosed by bronchoscopy (n = 7) or CT angiography (CTA) 10) who underwent after directional segmental localization target bronchus were enrolled. was performed at culprit traveling toward bronchus,...
Gastrointestinal arteriovenous malformation (AVM) is reported as one of the possible causes intestinal bleeding, and its occurrence in rectum rare. We report case a rectal AVM patient who experienced uncommon symptoms anal pain tenesmus was treated successfully with percutaneous transarterial ethanol sclerotherapy.
