“…The development of angiographic suites, catheters, guidewires, and materials for embolization has offered alternative therapeutic options for patients prior to surgery [12] . The fi rst elective embolization of the renal artery was performed in 1973 [9] , and since then several reports have been published [4,11,[13][14][15] .…”

Introduction: Renal hemorrhage is a major life-threatening condition that can be caused by trauma, operation, biopsy, as well as sudden spontaneous rupture of renal tumors or aneurysms. We report our experience with superselective segmental renal artery catheterization and embolization as therapeutic options for such cases. Patients and Methods: Over the last 8 years, 28 patients with severe renal hemorrhage were admitted for evaluation and possible further treatment. Twenty of them had a history of previous biopsy (6 of them one of a transplanted kidney), 1 patient had a recent percutaneous nephrostomy, 4 patients presented with renal mass ruptures (2 patients renal cell carcinoma, 1 patient angiomyolipoma, 1 patient hemorrhagic cysts), 1 patient had rupture of a renal aneurysm during delivery, 1 patient suffered bleeding after partial nephrectomy, and 1 patient was hospitalized after a car accident. They all presented with clinical signs of hemodynamic instability. Angiographic investigation of the kidneys preceded further intervention in all cases. 26 out of the 28 patients underwent superselective embolization of the specific bleeding vessel with the use of microcoils and/or Gelfoam particles. Results: All patients treated by superselective segmental renal artery embolization had a successful outcome, including a steady renal function and a stable clinical course. No complications occurred. Conclusion: Superselective segmental renal artery catheterization and embolization is a safe and efficient method for the treatment of patients with severe renal hemorrhage, preserving healthy renal parenchyma and renal function.

“…The reported rate of complications associated with palliative embolization is as high as 10-20%, with a mortality rate of 3.3%; the overall rate of complications (palliative and preoperative TAE) is 4.9%, with a mortality rate of 1.2% [13,30]. The major reported complications are renal failure and renal abscess.…”

“…TAE has produced good initial results, but is generally used for the palliative treatment of tumor-related signs and symptoms, such as gross hematuria, in patients with advanced RCC [29]. Moreover, some researchers have reported that TAE has yielded disappointing results with a high rate of complications [13,30]. Our study was based on the premise that TAE may contribute to longer survival provided it is as effective as nephrectomy.…”

Pilot study of transcatheter arterial ethanol embolization under closed renal circuit for large renal cell carcinomas

The safety of a new technique, designated "transcatheter arterial embolization (TAE) with aspiration via a balloon-occluded renal drainage vein" (TAE-ABOD), for the management of large renal cell carcinomas (RCCs). The subjects were 25 patients with RCC who underwent a total of 27 sessions of TAE-ABOD. This TAE-ABOD technique incorporates two procedures: balloon occlusion of renal drainage vein and infusion of absolute ethanol into the tumor-feeding arteries during aspiration of blood via a balloon catheter, thereby reducing leakage of absolute ethanol into the systemic circulation. Our primary endpoint was to establish a safe regimen for high-dose ethanol injection therapy, and our secondary endpoint was to assess global survival of the patients. The administered dose of ethanol ranged from 0.2 to 0.5 ml/kg [median: 0.34 (SD: 0.10) ml/kg], increased in a stepwise manner. The systemic ethanol concentration was measurable in 14 patients, and was less than 0.1 mg/ml in 12 and from 0.1 to less than 0.2 mg/ml in two. There were no major complications such as renal failure or renal abscess. TAE-ABOD can safely deliver a high dose of absolute ethanol for the treatment of large RCCs.

In this paper we present the first palynomorph and mollusc assemblages from the sediments in three different sections. From east to west, these are the Şevketiye (northern Biga Peninsula), the Tayfur (Gelibolu Peninsula) and the Kuzu harbour (Gökçeada) (parts of the Danişmen Formation) sections in the south and south-western side of the Thrace Basin (north-west Turkey), with the aim of obtaining information about the composition and structure of vegetation and climate during the Oligocene. The stratigraphic interval extends from late Rupelian to Chattian. The Danişmen Formation in the Şevketiye section yielded a palynomorph association with abundant coastal palms (Arecaceae; Lepidocaryoidae), and mangrove pollen (Pelliciera). A similar assemblage from the Kuzu harbour section was also obtained, with minor contributions of mangrove elements Nypa and Acrostichum aureum, Arecaceae type palm, undifferentiated dinoflagellate cysts and microforaminiferal linings. These palynomorph assemblages, combined with the mollusc data, indicate that low-lying coastal environments prevailed. In contrast, the palynomorphs from the Tayfur section represent a non-marine environment lacking mangrove elements, palm trees, dinoflagellate cysts and microforaminiferal linings. The diversity of angiosperm taxa in the Tayfur palynoflora, which form the bulk of the assemblage, indicates terrestrial vegetation. Quantitative palaeoclimate analyses are based on the Coexistence Approach method, and yield over 22 °C at the coast as indicated by mangrove elements and palms in the Şevketiye and Kuzu harbour palynofloras. For the Tayfur palynoflora, mean annual temperature ranged between 16.5 and 21.3 °C. This indicates a climate cooling, corresponding to the transition from Rupelian to Chattian, and resulted in the pollen changes from mangrove bearing coastal deposits to more inland vegetation.
