OBJECTIVE: To evaluate the safty and feasibility of the D2 radical resection of omental bursa and No.12p and No.8p for gastric carcinoma (GC). METHODS: Clinical data of 1801 GC patients undergoing D2 radical resection of omental bursa and No.12p and No.8p at Fujian Medical University Cancer Hospital from January 2000 to January 2010 were analyzed retrospectively. Inclusion case criteria: (1)age of 18 to 90 years;(2)pathologically diagnosed as GC and receiving D2 radical resection of omental bursa and No...

We present the case of a 54-year-old male patient diagnosed with a right upper lobe lung cancer and was referred for resection. Positron emission tomography-computed tomography scan showed a prominent vascular structure in the right lung, suspicious for vascular malformation. A computed tomography angiography was done, demonstrating an intercostobronchial trunk-pulmonary artery fistula. There was also non-tapering dilated wandering pulmonary artery coursing through the right lower lung without any abnormal connection with pulmonary veins and were supplying normal lung parenchyma...

Giant coronary artery aneurysms related to coronary fistula are rare, and the precise mechanisms by which they occur are unknown. We present a case of giant coronary artery aneurysm of the left coronary artery to the pulmonary artery fistula with a lack of internal and (or) external elastic lamina and medial degeneration.

Branch pulmonary artery stenosis is one of the most common complications late after the arterial switch operation. The pathophysiology of stenosis in these circumstances is very different to that encountered in with normally related great vessels. The LeCompte manoeuvre leaves the pulmonary arteries straddled and stretched over the aortic root which contributing significantly to the degree of stenosis encountered. Unilateral branch pulmonary artery stenosis rarely leads to significant symptoms in young patients with biventricular repairs; however, significant discrepancies in the split flows between right and left lung may place the patient in an unfavourable physiological position as they move in to middle age...

We report a rare case of right heart failure caused by distal aortic aneurysm. Although aortopulmonary fistula is a common complication of giant aortic arch aneurysm, right heart failure caused by mechanical pressure by aneurysm is very rare. A 79-year-old female patient presented dyspnea. Contrast computed tomography (CT) of the thorax delineated a 78 mm aortic arch aneurysm pressing the main to left pulmonary artery and a 40 mm pericardial effusion at maximum depth at posterior side. Echocardiography showed the acceleration flow from main to left pulmonary artery and moderate pulmonary hypertension...

A 39-year-old Japanese woman was diagnosed with a pulmonary arteriovenous fistula (PAVF) complicated by paradoxical cerebral infarction during pregnancy. She received an inferior vena cava filter (IVCF), but it was difficult to indwell because of the risk of repeat thromboembolism via PAVF. Therefore, we temporarily occluded the pulmonary artery with a balloon to prevent free thrombi from reaching the IVCF. Detection and treatment of PAVF are recommended in fertile young women. Obstruction of the pulmonary artery trunk with a balloon catheter may be useful during IVCF removal in patients with untreated PAVF...

RATIONALE AND OBJECTIVES: This prospective study aimed to evaluate the diagnostic performance of dual-input computed tomography perfusion technique (DI-CTP) in identifying the bronchial-pulmonary artery fistula in patients tuberculosis with massive hemoptysis. MATERIAL AND METHODS: Twenty patients with tuberculosis with massive hemoptysis were enrolled from January 2015 to December 2015. The association between DI-CTP parameters and the diagnostic outcomes of digital subtraction angiography was assessed...

The formation of a fistula between the right pulmonary artery and the left atrium via a sac is a very rare cyanotic congenital cardiopulmonary defect. A fistula between the pulmonary artery and left atrium may cause cardiac failure in utero. It can safely be treated surgically and in selected cases closure can be performed with transcatheter insertion of a device. In this article, we present a case with a fistula between the right pulmonary artery and the left atrium that was considered unsuitable for transcatheter closure and was safely treated surgically...

Coronary arteriovenous fistula in continuity with the aortic arch by abnormal vessels running along the surface of the pulmonary artery is rare. We describe two cases of this rare and unique arteriovenous network and discuss the issue of diagnosis and treatment with a review of the literature.

Abdominal aortic aneurysm (AAA) is most commonly defined as a maximal diameter of the abdominal aorta in excess of 3 cm in either anterior-posterior or transverse planes or, alternatively, as a focal dilation ≥ 1.5 times the diameter of the normal adjacent arterial segment. Risk factors for the development of AAA include age > 60, tobacco use, male gender, Caucasian race, and family history of AAA. Aneurysm growth and rupture risk appear to be associated with persistent tobacco use, female gender, and chronic pulmonary disease...

BACKGROUND: Guidelines allow percutaneous pulmonary valve implantation (PPVI) in conduits above 16mm diameter. Balloon dilatation of a conduit to a diameter>110% of the original implant size is also not recommended. We analyzed patients undergoing PPVI in such conditions. METHODS AND RESULTS: Nine patients (May 2008-July 2016) from 8 institutions underwent PPVI in conduits <16mm diameter. Five patients with 16-18mm conduit diameter underwent PPVI after over-expansion of the conduit>110%...

OBJECTIVES: Systemic left-to-right shunting causes pulmonary arteriopathy, leading to progressive cardiopulmonary failure and a poor prognosis. In this study, we examined the extraglycemic effect of a synthetic glucagon-like peptide, exendin-4, on pulmonary arteriopathy regression and cardiopulmonary function in nondiabetic rats. METHODS: Pulmonary hypertension (PH) was induced by monocrotaline (60 mg/kg, subcutaneous) injection followed by the creation of an aortocaval fistula...

OBJECTIVES: With the increasing use of multi-detector CT, the number of detected cases with coronary-to-pulmonary artery fistula (CPAF) has increased. Several previous studies reported severe cases of angina, but no appropriate tests to evaluate myocardial perfusion for patients with CPAF have been established. We evaluated the hemodynamic characteristics of CPAF using thallium-201 (Tl-201) single photon emission computed tomography (SPECT). MATERIALS AND METHODS: Tl-201 SPECT was performed in 17 patients with CPAF, but without evidence of coronary artery disease on coronary computed tomography angiography (CCTA) (age, 58...

The neck, being not protected by skeleton, is vulnerable to external trauma and injury which can involve blood vessels, muscles, nerves, and trachea. Carotid injuries can be potentially life-threatening by hemorrhage and stroke. We present a case of a 26-year-old manual worker who presented a neck injury caused by a metallic projectile. The injury involved the right common carotid artery with an internal jugular vein fistula, and tracheal damage. The patient was managed with surgical repair of the tracheal lesion, reconstruction of the carotid section using a PTFE graft bypass, and ligation of the internal jugular vein...

Tracheobronchomalacia is a rare but clinically troublesome condition in paediatrics. The softening of the major airways - which can include some or all of the tracheobronchial tree can lead to symptoms ranging from the minor (harsh barking cough, recurrent chest infections) to severe respiratory difficulties including prolonged ventilator support and 'near death attacks'. The causes are broadly divided into intrinsic softening of the airway wall which is considered a primary defect (e.g. syndromes; post tracheo-oesophageal fistula repair; extreme prematurity) or secondary malacia due to external compression from vascular structures or cardiac components...
