Rapid Formation and Hybrid Treatment of a Large Superior Mesenteric Artery Aneurysm.

BACKGROUND Superior mesenteric artery (SMA) aneurysms account for about 5.5% of all visceral aneurysms, and are most commonly secondary to infectious causes or dissection. They tend to expand and rupture.

Towards More Efficient Rényi Entropy Estimation.

Estimation of Rényi entropy is of fundamental importance to many applications in cryptography, statistical inference, and machine learning. This paper aims to improve the existing estimators with regard to: (a) the sample size, (b) the estimator adaptiveness, and (c) the simplicity of the analyses. The contribution is a novel analysis of the generalized "birthday paradox" collision estimator.

Influence of Selective Biochemical and Morphological Agents on Natural History of Aneurysm of Abdominal Aorta Development.

BACKGROUND The development of abdominal aortic aneurysm (AAA) is probably influenced by many factors. The role of some of these factors, such as intraluminal thrombus (ILT) or cystatin C serum levels, remains controversial. Proving their influence could have therapeutic implications for some patients with AAA.

Material And Methods: Over the last 18 months we operated on six patients with large adrenal gland cysts in our centre. This consisted of 8.2% of all patients treated in said period due to adrenal gland pathologies.

The local spread of pheochromocytoma after adrenalectomy with a rupture of the tumor capsule at the time of the surgery.

Introduction: We present a case of a 29-year-old patient treated due to fully symptomatic pheochromocytoma of the right adrenal gland.

Case Presentation: Patient was operated on and an open right-sided adrenalectomy was performed. At the time of the surgery, a rupture of the tumor capsule occurred.

Endovascular treatment of traumatic rupture of thoracic aorta: long term results.

Background: The aim of this study was to evaluate the endovascular treatment of acute post-traumatic thoracic aorta rupture. Rupture of the thoracic aorta is caused in a majority of cases by blunt trauma of the chest as a result of motor vehicle accident. Hypovolemic shock due to massive hemorrhage leads to death in almost 90% of victims.

Unilateral laparoscopic adrenalectomy following partial transsphenoidal adenomectomy of pituitary macroadenoma - life-saving procedure in a patient with ACTH-dependent Cushing's syndrome.

Introduction: Cushing's disease is the most common cause of endogenous hypercortisolemia, in 90% of cases due to microadenoma. Macroadenoma can lead to atypical hormonal test results and complete removal of the tumour is unlikely.

Case Report: A 77-year-old woman with diabetes and hypertension was admitted because of fatigue, proximal muscles weakness, lower extremities oedema, and worsening of glycaemic and hypertension control.

The effect of surgical treatment of phaeochromocytoma on concomitant arterial hypertension and diabetes mellitus in a single-centre retrospective study.

Introduction: Phaeochromocytoma is one of the numerous causes of secondary hypertension. Furthermore, phaeochromocytoma may first present with type 2 diabetes mellitus. The objective of our study was to evaluate the effects of adrenalectomy on patient recovery with regards to normotension and well-controlled glycaemia.

Location and incidence rate of anastomotic aneurysms--own clinical material and literature review.

Unlabelled: Anastomotic aneurysms occurs at various levels of arterial system. Determining their location and incidence rate required investigation of large patient clinical material.

Material And Methods: In the years 1989-2010 in local centre 230 anastomotic aneurysms were operated in 180 patients.

A spontaneous paraganglioma-pheochromocytoma syndrome.

We present a case of a 40-year old woman diagnosed with a four-place spontaneous paraganglioma-pheochromocytoma syndrome, which was treated surgically. The presence of the succinate dehydrogenase complex subunit D (SDHD) mutation that causes the pheochromocytoma was confirmed but no mutations in the family members were found. After the excision of the paragangliomas located in the areas of the division of carotid arteries, and mediastinum, as well as a tumor on the left site of the celiac trunk, the patient remains asymptomatic and is regularly followed-up.

Anastomotic aneurysms--20-years of experience from one center.

Unlabelled: Anastomotic aneurysms may develop after any type of vascular surgery, in different areas of the arterial system, and require reoperation. The frequency of occurrence of the above-mentioned is estimated at 1-5%.

Material And Methods: During the period between 1989 and 2010, 180 patients with 230 anastomotic aneurysms were subject to surgical intervention at the Department of General and Thoracic Surgery, Warsaw Medical University.

Laparoscopic adrenalectomy in a patient with situs inversus levocardia.

The article presents a case of an adrenal adenoma (Conn's syndrome) in a 50-year-old man with situs inversus with levocardia. Laparoscopic adrenalectomy was performed and the patient made a full recovery. It has been concluded that diagnostic assessment by means of imaging techniques providing details of the organ anatomy and the experience of the medical team are the key factors determining the outcome of such surgery.

Is tumour size a contraindication to laparoscopic adrenalectomy? Case report.

The authors present a case report of a patient with a large, hormonally silent tumour of the right adrenal gland. Due to the patient's numerous strains, the necessity of two gynaecological operations, and treatment of broken bones, adrenalectomy was contraindicated for 2 years. After that time, the size of the tumour reached 18 cm × 12 cm.

Laparoscopic treatment of Cushing's syndrome in a woman in late pregnancy - a case presentation.

Hypercortisolaemia during pregnancy constitutes a serious threat to life of the mother and fetus and may be associated with adrenocortical carcinoma. The objective of this study is to present the usefulness of laparoscopic procedures in treating adrenal tumours in such cases. One 21-year-old woman, 24 weeks pregnant, with hypertension and Cushing's syndrome due to a left adrenal tumour, underwent laparoscopic adrenalectomy followed by hydrocortisone replacement.

Laparoscopic adrenalectomy--assessing the learning curve.

Unlabelled: Laparoscopic adrenalectomy (LA) has become the "gold standard" for treatment of most of adrenal tumors in last few years. It has many benefits comparing to open surgery, but still is considered as complicated procedure requiring experienced surgical team.

The Aim Of The Study: was to assess the learning curve of laparoscopic adrenalectomy and the outcome of the first consecutive 154 LA.

The study presented three cases of patients diagnosed with adrenal tumors subject to surgical intervention during the past 6 months in our Department. The patients presented with radiological diagnostic difficulties, as to the character and location of the primary tumor. The aim of the study was to demonstrate differences between radiological examination results and the factual situation observed during the adrenalectomy.

Laparoscopic treatment of a huge mesenteric pseudocyst - case report.

Intra-abdominal cysts and pseudocysts are rarely occurring lesions. Their incidence is reported to be 1 per 100 000-250 000 hospitalizations. The lesions' rarity and their mostly asymptomatic development causes troubles in early recognition and treatment.

Life Threatening Complication during Treatment of Erysipelas due to Undiagnosed Ischemia of the Calf.

Erysipelas is a superficial skin infection due to streptococci strains, which usually responds well to conservative treatment. Coexisting undiagnosed ischemia of the extremity may lead to severe complications. 57-year-old man developed large, circumflex ulceration of his right calf within two weeks before the admission after three-month treatment of erysipelas.
