Background: Unfractionated heparin (UFH) has been conventionally used during coronary angiography (CAG). Whether to use unfractionated heparin or not, has been unanswered. Methods: Hundred patients who underwent CAG through femoral route were assessed. CAG was performed without using unfractionated heparin and embolic or thrombotic event and vascular complications were observed during and after procedure. Results: The right femoral approach was used in 92% of cases and the left in 8%. Those patients who underwent radial route were excluded. Male (65%) were exceeded the female and smoking (50%) was the major predisposing factor. There were no embolic or thrombotic event and vascular complications such as bleeding, heamatoma, pseudoaneurysm formation, A-V fistula and retroperitoneal bleeding during or after procedure. Conclusions: Routine elective CAG have shown no significant complication during or after the procedure without UFH.

Introduction: The aim of this study was to present the incidence of the vascular complications that had to be surgically treated during the two-year period of transfemoral cardiac catheterization procedure and to identify the risk factors associated with the complications.Methods: A retrospective two-year study of post-catheterization complications with the six-month postoperative follow-up and analysis of risk factors was done. Patients with cardiovascular diseases who underwent therapeutic or diagnostic coronary angiography in the period of 2012-2013 were included in the study. A total of 1320 patients were subjected to catheterization for coronary angiography, of which 24 had vascular complications that had to be surgically treated. Indications for operative treatment included rapid growth of pseudoaneurysm, hemorrhage, large hematoma, hemodynamic instability, failure of the targeted compression therapy.Results: Twenty-four patients experienced some kind of post-operative complication. Infection and dehiscence of surgical wound were the two most common complications. There were no fatalities. The average length of a hospitalization was 4 days. The important risk factors are gender (women more than man), obesity, concomitant use of anticoagulation therapy and antiplatelet therapy after catheterization.Conclusion: Insufficient length of the compression of the punctured place and increased risks of a pseudoaneurysm formation, such as female gender, obesity, and use of a combined anticoagulant therapy are the main causes of these complications. Late vascular complications are not uncommon.

Highlights The distal ulnar palmar approach for both coronary angiography and intervention was safe, feasible, and reliable in our case series of 15 consecutive patients. The distal ulnar palmar approach was not a technical limitation for coronary angiography and interventional procedures in our cohort of patients. Further studies are needed to understand the potential benefits for patients and avoid medical futility. Abstract Background: Transradial and translunar approaches, associated with fewer bleeding and vascular complications than transfemoral access, have been adopted and increasingly utilized following a “radial-first strategy.” Approaches that are innovative and more distal than standard radial approaches are available, even if their clinical utility is under debate. At the price of a more difficult puncture and risk of access failure, there are possible ergonomic advantages, with lower risk of upstream artery occlusion and shorter hemostasis. Aim: The study was aimed at proving the preliminary feasibility, safety, and reliability of the right distal ulnar palmar approach in 15 consecutive patients. Results: In 15 out of the 17 patients enrolled, the distal ulnar access in the palmar artery was feasible, safe, and reliable. The diameter of the distal ulnar artery was greater than that of the distal radial in the anatomical snuff box. There were no significant complications. Conclusion: The distal ulnar palmar approach for both coronary angiography and intervention was safe, feasible, and reliable. It was not a limitation for coronary angiography and interventional procedures in our cohort of patients

Simultaneous ST-segment elevation (SST-SE) in anterior and inferior leads in the setting of ST-segment elevation myocardial infarction is often confounding for a cardiologist and further more challenging is the angiographic localization of the culprit vessel. SST-SE can be fatal as it jeopardizes simultaneously a larger area of myocardium. This phenomenon could be due to “one lesion, one artery,” “two lesions, one artery,” “two lesions, two arteries,” or combinations in two different coronary arteries. We have discussed an index case where we encountered a phenomenon of SST-SE and coronary angiography demonstrated “two lesions, one artery” (proximal occlusion and distal critical diffuse stenoses of the wrap-around left anterior descending [LAD] artery) and “two lesions, two (different coronary) arteries” (previously mentioned stenoses of the LAD artery and critical stenosis of the posterolateral branch of the right coronary arteries). We have also described in brief the possible causes of this phenomena and their electroangiographic correlation of the culprit vessels.

Continuous Bleeding

Ascending aortic aneurysms involving the proximal aortic arch, arising anywhere from the aortic valve to the innominate artery, represent various problems in which open surgery is generally required. Surgical options include excision of the aortic pathology or wrapping the aneurysm shell with an aortic Dacron graft. Intervention using the latter method can lead to extravasation of blood along the suture lines resulting in continuous bleeding within the periprosthetic space. The Cabrol technique was developed as a method for decompression of postoperative leaks by the formation of a conduit system from the periprosthetic space to the right atrium. The coronary ostia are anastomosed to a second graft in an end-to-end fashion, which is then anastomosed to the ascending aortic conduit side to side. The native aorta is then sewn around the prosthesis, hereby creating a shunt to drain anastomotic leakage. This shunt reduces postsurgical risk of pseudoaneurysm formation and normally closes a few days following surgery. We discuss the case of a patient who underwent Cabrol’s variation and six months later was demonstrated to have a patent shunt.

Objective. Left circumflex (LCx) artery originating from the right coronary arterial (RCA) system has been reported as the most common form of anomalous origination of a coronary artery from the opposite sinus (ACAOS). However, some studies claim that RCA originating from the left coronary sinus (LCS) is the most frequent form. The aim of this study was to determine the most common type of ACAOS in a single center.Materials and Methods. The database of the catheterization laboratory was retrospectively searched. All patients who were performed coronary angiography between 1999 and 2006 were included to registry. All examinations were carefully analyzed to determine the most frequent type of ACAOS.Results. We detected ACAOS in 35 cases (16 RCA originating from the LCS, 13 LCx from the RCS or the RCA, and 6 others) out of 5165 coronary angiograms. The most common form was RCA originating from LCS. Moreover, we revealed that 5 cases with RCA originating from the LCS were previously misdiagnosed and not reported as a coronary anomaly.Conclusions. RCA originating from the LCS was the most common form of ACAOS in our registry. The high change of misdiagnosis or underreporting of this anomaly could have biased the true prevalence.

The most common testicular neoplasms in dogs are seminoma, leydigocytoma and sertolioma, affecting middle--aged and elderly dogs, where cryptorchidism is a predisposing factor, as well as some breeds. It can occur alone or, less fren-quently, concurrently, generally affecting the same testicle. This study aimed to report the case of a non-cryptorchid 14-year--old mixed breed dog diagnosed with seminoma and sertolioma, each in a testicle. The animal showed an increase in scrotal volume, with no changes in other clinical parameters on physical examination. On ultrasound examination, it was possible to observe alterations suggestive of neoplasia in both testicles and prostatic alteration suggestive of benign prostatic hyperplasia. Complementary blood count and biochemical tests were performed and, as treatment, orchiectomy was performed. Fragments were collected from both testicles and sent for histopathological examination. Microscopy of the left testicle showed the presence of round cells, multiple and evident nucleoli, cells in different phases of mitosis and binucleation, these changes being compa-tible with seminoma. In contrast, in the right testicle, spindle and elongated cells (pseudo-lobular) were observed, presence of long cytoplasmic projections with rounded ovoid nucleus, spindle cells and degeneration of seminiferous tubules, compatible with sertolioma. It was observed that physical examination associated with ultrasound was efficient to detect the presence of neoplasms, being validated by histopathological examination. Orchiectomy was an assertive treatment indicated for this case.

BACKGROUND: Ehlers-Danlos syndrome (EDS) type IV is a heritable disorder of connective tissue that is mainly associated with vascular maladies such as aneurysms, pseudoaneurysms, and dissections with or without spontaneous rupture. Historically, vascular complications in EDS IV have been treated conservatively whenever possible, due to the high morbidity and mortality after vascular interventions, whether open or endovascular. We present a case of a ruptured pseudoaneurysm of the right common iliac artery in a 18-year-old male, who was successfully treated by endovascular approach and later diagnosed with EDS type IV. CASE PRESENTATION: A 18-year-old male patient was admitted in ER with sharp pain in the right hypogastrium, hypotensive and with reduced blood parameters. Multiphasic modern computed tomography (MDCT) scan of abdomen and pelvis revealed massive ride sided pelvic and retroperitoneal hematoma. The presence of pseudoaneurysms on both common iliac arteries (CIA) was detected, with small ulcer on the right side and a focal dissection on the left side. An urgent endovascular repair of the ruptured pseudoaneurysm on the right CIA with covered stent was performed. Patient’s laboratory parameters and clinical status improved significantly within the next few days. CONCLUSIONS: Vascular repair in EDS-IV patients carries significant risk and should be indicated very carefully. Endovascular treatment for these patients is feasible and should be considered as an alternative to open surgery in some challenging cases as this one.
